Ask a Female Engineer: Thoughts on the Google Memo ycombinator.com

hedgew 1 day ago  replies      
Many of the more reasonable criticisms of the memo say that it wasn't written well enough; it could've been more considerate, it should have used better language, or better presentation. In this particular link, Scott Alexander is used as an example of better writing, and he certainly is one of the best and most persuasive modern writers I've found. However, I can not imagine ever matching his talent and output, even if I practiced for years to try and catch up.

I do not think that anyone's ability to write should disbar them from discussion. We can not expect perfection from others. Instead we should try to understand them as human beings, and interpret them with generosity and kindness.

Why We Terminated Daily Stormer cloudflare.com

We can make burglary illegal without any additional explanation of why burglary is "wrong". This is because it is part of understanding the concept of burglary to know that it is wrong. It's the same sort of logic that applies to Nazi propaganda: it is wrong simply because it is Nazi propaganda. We understand what it is and what they are saying, so we do not need to go to additional lengths to explain why it is wrong. It should be silenced for no other reason than that it is Nazi propaganda. To promote Nazi propaganda is to undermine the social contract itself about what constitutes free speech. It is a mistake of Enlightenment political philosophy to say that every decision we make about what constitutes right and wrong must derive ultimately from basic principles by logical reasoning. In many cases merely understanding a concept suffices to directly condemn an activity and Nazi propaganda is almost the best example of how we can, without further conversation, simply say "NO"... we are not going to help you promote this and we are not going to politely explain to you why we do not agree with your views. All this talk about free speech and Nazis is nonsense. I support Cloudflare's decision.

>Let me be clear: this was an arbitrary decision. It was different than what Id talked talked with our senior team about yesterday. I woke up this morning in a bad mood and decided to kick them off the Internet. I called our legal team and told them what we were going to do. I called our Trust & Safety team and had them stop the service. It was a decision I could make because Im the CEO of a major Internet infrastructure company.

U.S. judge says LinkedIn cannot block startup from public profile data reuters.com

I fully support this decision. If you're offering a service that is public, with the intent to your users that such information will be available publicly, you cannot then police what users of that data you consider to be "public" because it serves your business interest.

LinkedIn, of course, wants to get all the benefit of the public Internet with providing as little as they can. This, coming from someone who used to work at LinkedIn.

These companies have built their fortunes on the public Internet and now that they are successful they seek to not pay homage to the platform that give them their success. It's very clearly anti-competitive, and bad for users. LinkedIn should be forced to compete based upon the veracity and differentiation of their service, not because they have their users' public data held hostage from competitors.

This is just a preliminary injunction and the court has not even heard or ruled on this case. They just allowed HiQ to access the data while they wait for the scheduled court hearing to begin. The court may eventually rule very differently once they have heard all the evidence presented and weighed up existing applicable case law.

The judge who issued this injunction - Edward Chen, is also the judge presiding over the Uber drivers as independent contractors class action case.

Being a programmer not a lawyer, I like the idea of more rights for scrapers. I don't want to see the internet partitioned away and owned by a few companies, especially when that information is often called a "public profile".

LinkedIn has full control over this, it's their site. What they are fighting for is the ability to choose who gets public access to various pieces of information; which its member do not get control over.

This seems very at-odds with previous rulings (specifically, relating to craigslists many past dealings). Strikes me as being very unlikely to stand up to appeal. Also, linkedin will likely modify their websites behavior (make you click to agree before you view a profile) which would create a binding 'click wrap' stopping companies from scraping them.

razwall 2 days ago 1 reply      
From reading the ruling, the injunction was based on a finding that HiQ raised serious questions about whether LinkedIn blocking HiQ's scrapers constituted a violation of California's unfair competition law by violating the spirit of federal antitrust law.

HiQ argued that LinkedIn has a monopoly on "the professional networking market" and is unfairly exploiting that monopoly to gain an advantage in the data analytics market. HiQ showed that LinkedIn might be developing an analytics product that competes directly with their Skill Mapper product.

drngdds 2 days ago 1 reply      
I'm confused. Is the judge saying that LinkedIn can't use the law to ban HiQ from scraping their profiles or that they can't implement technology to block scrapers? The former seems reasonable but the latter seems like an unjustified restriction on how they operate their site.

thinbeige 2 days ago 0 replies      
Does the startup want to scrape the public profiles which you see when logged out of LinkedIn? If yes, this profile data is of little value because it's probably 5% of the real profile data (mainly just the summary) and often there are no public available at all, many times these profiles are turned off for public virw.

Or do they mean the 'public' profile which you see when logged in? If yes, this would be a real case because this is awesome data I would like to scrape and which you could build interesting business cases with.

This type of decision might also impact Yelp or any others in similar businesses. Currently their API limits a top few reviews per business via their API, and also prohibits "scraping" of data in other means.

I was going to do some experiments with larger datasets from businesses in a region, but quickly found that's not possible.

I do find it odd that LinkedIn is fighting this considering they outright steal your contact list and will spam your friends and family for years.

Recently I was setting up my new phone and thought about installing their app and I thought to myself, why?

Eventually that thought came back to me when I was attempting to update my profile and simply decided to delete it entirely.

Does anyone know how they do this scraping from a technical standpoint. The articles allude to it being the same as data Google/Bing spiders, which can clearly access more data that average internet IP for making their result summaries. I had assumed big sites whitelisted specific crawler IP ranges or User-Agents for the search giants. Do they somehow spoof this?

Well, good, right?

This is the same outcome most of us wanted between Swartz and JSTOR, and perhaps with Malamud and PACER. No technical control can be in the right place, but we can hope for a common understanding (maybe eventually law?) that terms of service may demand or prohibit some things but not anything.

I would prefer if my LinkedIn data was not public in the sense that one should have to be logged in to see it, and ideally I should be able to see who viewed it. If you have to be logged in to look, they can obviously limit the number of profiles you can view to prevent scraping.

On one hand, LinkedIn is like Twitter, Craigslist and Delicious in that it has sat on a treasure trove of data without helping users mobilize it. (All of the premium services they offer are outright lame; if there was a market for premium services we might seem some good ones.)

On the other hand, privacy is an issue too. LinkedIn lets you download a spreadsheet with the email addresses of all your connections, and if you have a lot of connections you will regularly get e-mail messages from life coaches, "managing directors", software development outsourcers, "SEO experts", and all kind of BS artists.

IANAL but I suspect the forthcoming GDPR will make this illegal for EU customer data. It gives users greater control over their data, so I wouldn't be surprised to find that it corresponds with this judgement, i.e. if a user determines data to be publicly available, it must be made to be so.

Anyone know whether this is right?

And BTW in case you're not aware, if you hold data from any EU citizens you'll be required to comply with the GDPR regardless of where you're located.

The question of "data protection" hasn't been discussed enough here - it may well be that Linkedin has no case against HiQ, but if HiQ is scraping people's PII in the EU they are required to have the permission of the data subjects.

I'm curious how a ruling in this might potentially impact Google (or not). Google is scraping those same profiles, but Linkedin clearly has no issue with that because it drives traffic to their site. But Google is also making money off of those profiles.

How can Linkedin argue that Google be allowed to scrap but other third party cannot?

Microsoft/LinkedIn has so much more juicy and actually private data that nobody can scrape, I don't understand why they would even make a scene and tarnish their image over scraping. They know who declines connection requests from whom, when a CEO starts looking for a new job, and so on.

When these decisions are made, I hope they come with technical guarantees on ease of accessibility to data.

For instance, "buried in 6 layers of obfuscated XML" and "accessible in O(N^3) time" would both be implementations that are not "blocking" the data but they would still be extremely difficult to use.

This is neat, but based on the title, I thought this was going to be a bit more informative about _how_ engines work, and how each subprocess contributes toward the end goal.

What I saw instead was a subset of subprocesses in isolation from each other, presented in an admittedly artistic fashion. It's impressive, and maybe the purpose is more to whet one's appetite for more information rather than be informative in itself, but that's not really what I was expecting or hoping for.

IMO what is really clever about this is that it is a "sales" video - except you dont realise you are being sold to until the end, by which time you've enjoyed the video so much, the pitch at the end is reasonable.

And you've shown what the value is long before I asked myself the question "how much" - which I usually ask early in the process - but not here.

At least that is how I found it... great work.

What I found surprising about the video was that it made an engine seem, somehow, less complex and daunting. I'm sure that's a bit of an illusion created by the way the engine is taken apart (and the fact that it's not in a car and therefore you can rotate it as you need it, etc), but amazing work.

I just subscribed to the video course and I can see the preorder offer is a no brainer, skimming through the PDF provided I can see there is enough value on it to easily make it worth the $20 by itself.

So as a suggestion: Highlight the PDF and its content on the preorder page, there is only one mention about it but it doesn't specify its contents.

One of funnest projects I worked on at Corel was called "Smart Graphics Studio" (I'm guessing most of the people who worked on it also read HN, so "Hi!"). It was an absolutely stupid idea: Some insane PGM read that XSLT could transform any XML into any other XML. Then they read that SVG was XML. They put 2 and 2 together and got a billion: You could draw a picture in SVG and then modify it intelligently (through XSLT) using some XML data set.

Of course the opposite is actually a brilliant idea (at least at a time when XML was still popular): Take an XML dataset and visualise it in SVG using XSLT transformations (well... yeah... doing it all in XSLT is still insane, but you get the idea).

Anyway, we built a very high performance SVG viewer (for the time, anyway) from scratch. We built an SVG/Javascript widget library. We built an incredibly impressive data manipulation library in XSLT (ok... yeah... insane).

Fun times. And all nearly 20 years ago. It really was ahead of its time. Of course the end finally had to come. The PGMs sold this thing to a certain aviation company with the promise that it would automatically build circuit diagrams from their XML chipset database (because.... XSLT!)

When Vector took over Corel, they very rightly dropped our division like a hot potato (we had something like 3 PGMs per developer). It was quite unfortunate because the developers and QA people I worked with there were some of the best I've every had the pleasure of working with. I've always waited for something to come of SVG and really wish we had been able to release something that wasn't crazy so that people could see what the potential was.

Edit: In my old age I'm losing track of time. It seems that Vector acquired Corel in 2003, so that's only 15 years ago :-)

This showcases what's wrong with SVG: It does way too much!

To be useful as a vector image format, there should be strict rules (and less cruft). Why is there no libsvg like libjpeg or libpng? Why have interaction as part of an image format?

SVG lives in an uncanny valley between jpeg and flash/js.

I think there is still a big need for a real vector interchange and display format. Right now people pick a "good" subset of SVG. Or even fallback to fonts.

My dream vector format:

- Pixel perfect across implementations at 50%,100%,200% renderings. At least grid aligned lines.

- Lossless roundtrip across apps. Start in Illustrator, edit parts in Inkscape, other parts in Animate, untouched things stay exactly the same.

- Standard zero dependency C reference implementation: Stream in, bitmap out.

SVG hits a performance ceiling as number of elements increases.Canvas, since it's rasterized image can handle a rasterized representation of millions of SVG elements.

However as Canvas dimension increase, it will hit a performance ceiling.

- loading bar until website is fully loaded

- animated buttons that bounce and flash

- full screen 2 second transitions from page to page

- all in one page, no urls!

While SVG can do a lot, there are certain things that it isn't optimized for. In particular animating lots of shapes simultaneously. The animation of the globe exploding into a bunch of triangles from the slides is a good (bad?) example of this. Also, there can also be inconsistencies is in the rendering of SVGs between browsers.

SVG is good as long as it's not abused.

All the kb saving are meaningless with performance issues caused by lots of nodes, gradients, etc.

It's great for responsive icons, but for a full interactive UI with illustrations bitmaps are the better choice IMO unless you really need dynamic scaling.

Just because you can do it doesn't mean you should.

I've used SVG to design custom PCBs using traces as magnetic coils, something that, surprisingly, doesn't have a good industrial software package for. Everything in PCB design software is geared toward routing wires conveniently between components, but if you try to actually use the wires as actual components, it's almost impossible to freely design. And even regular PCB design software feels almost unchanged since the 1980s or 1990s. Incredibly clunky.

Here's a good Hackaday article on converting SVG to PCB file formats:http://hackaday.com/2016/01/28/beautiful-and-bizarre-boards/PCBModE is one package I tried for a while:http://pcbmode.com/Boldport uses this toolchain to make beautiful PCBs relying heavily on SVG: https://www.boldport.com/

I had a hard time with all these packages, however, and ended up just hacking it together by hand with python code and outputting in KiCAD format. I wasn't even able to get KiCAD to read/render it properly (too many weird elements), but since OSH Park (where I got my PCBs from) takes KiCAD format directly and gives you a preview, that all worked fine, and when I ordered my PCBs, they arrived in working condition just fine the first time.

https://oshpark.com/

So yeah, SVG can do a lot, including make funky PCBs.

I wonder if we should encourage print designers to switch to svg (that is, if they don't already... it's not a world I know much).

I have in mind all those concerts or various events' png/jpeg files that are dropped on the web here and there. If they were svg files, it would be made easier for search engines to index their content.

Even without that, svg totally rocks. About a decade ago, I played with SVGWeb and made a showcase carousel presenting screenshots of projets with automated reflection on them (like it was common back then, a reverse image on bottom of actual image with a gradient from transparency to white to make an effect like if the ground was a mirror). I just had to upload a plain screenshot and everything was automated, I was mind blown, and surprised we seemed to go the canvas way instead (not so much, in retrospect).

Nowadays, I often make my icons as svg react components. It makes it so much easier to change their color or saturation on hover, this is very cool. We probably still have a long way to go to exploit all of svg potential.

Flash has the "advantage" that it's used almost exclusively for advertisments. Mostly pretentious people (artists, photographers etc) have websites made of flash. So, by turning off Flash, you block the bulk of annoying ads. And you lose little by disabling Flash.

Would the same be true for SVG ? Would it be used mostly for ads, too ? Or even, can you selectively block only the SVG used for advertisments ?

I've had a similar problem. In updating my portfolio site recently, I noticed a vast majority of links were dead. Not just live projects published maybe 3 years or more ago (I expect those to die). But also links to articles and mentions from barely one year ago, or links to award sites, and the like. With a site listing projects going back ~15 years, one can imagine how bad things were.

I had to end up creating a link component that would automatically link to an archive.org version of the link on every URL if I marked as "dead". It was so prevalent it had to be automated like that.

Another reason why I've been contributing $100/year to the Internet Archive for the past 3 years and will continue to do so. They're doing some often unsung but important work.

The article indicates that the "free" stuff on the internet was hidden away in weird places - ftp servers and the like. No google to find it for you, the only way was by word of mouth, or I guess via published book.

Answers a question I always had about "Snow Crash" by Neal Stephenson. The main character, Hiro Protagonist (I still giggle at that name), sometimes did work as a kind of data wrangler - "gathering intel and selling it to the CIC, the for-profit organization that evolved from the CIA's merger with the Library of Congress" (Wikipedia).

I always wondered what made that feasible as a sort of profit model, and I guess now I know - that was the state of the internet in 1992, when the book was published. Seems like a way cooler time period for Cyberpunk stuff, I'm almost sad I missed it :(

I don't think this is necessarily a bad thing. For one, the 80/20 rule applied back then just as it does today, so most of what's lost is crap to begin with. It's no different than in the real world: surely nobody's lamenting that you can't pick up a copy of Fordyce's Sermons anymore (and I presume that it'd be long forgotten if not for Austen). While some valuable resources were undoubtedly lost, most live on re-posted elsewhere, like memes, but in a "good" way.

Secondly, the book is more analogous to a map or dictionary, and it ought to be a descriptive source, not a prescriptive one. Some language purists may disagree, but I could care less :-). And similar to an old, outdated, map, you'd expect that the details may have changed, but the landmarks are most likely still accurate. NASA's still nasa.gov, MIT's still mit.edu -- well, IIRC www.mit.edu used to point to their library's portal, and web.mit.edu their main page; I see that's changed -- and CompuServ still...exists.

I wouldn't be surprised if private donations will eventually be responsible for the eradication of Malaria (1000 deaths daily, much more suffering and cost to society).

If you're in tech you're likely to be in a great position to create value beyond your company.

A different view on Gates' charity work: [1]

Some highlights:

"The first question concerns accountability... The Foundation is the main player in several global health partnerships and one of the single largest donors to the WHO. This gives it considerable leverage in shaping health policy priorities and intellectual norms..."

"Depending on what side of bed Gates gets out of in the morning, he remarks, it can shift the terrain of global health..."

"Its not a democracy. Its not even a constitutional monarchy. Its about what Bill and Melinda want..."

"In 2008 the WHOs head of malaria research, Aarata Kochi, accused a Gates Foundation cartel of suppressing diversity of scientific opinion, claiming the organization was accountable to no-one other than itself."

"As Tido von Schoen Angerer, Executive Director of the Access Campaign at Mdecins Sans Frontires, explains, The Foundation wants the private sector to do more on global health, and sets up partnerships with the private sector involved in governance. As these institutions are clearly also trying to influence policymaking, there are huge conflicts of interests... the companies should not play a role in setting the rules of the game."

"The Foundation itself has employed numerous former Big Pharma figures, leading to accusations of industry bias..."

"Research by Devi Sridhar at Oxford University warns that philanthropic interventions are radically skewing public health programmes towards issues of the greatest concern to wealthy donors. Issues, she writes, which are not necessarily top priority for people in the recipient country."

eradication of Malaria (1000 deaths daily, much more suffering and cost to society).

If great efforts are made to eradicate diseases in an area that has historically been subjected to various diseases such that the local population has adopted the reproduction strategy of having large amounts of offspring to counter premature deaths, but upon eradication/reduction of said diseases there is significant delay in the abatement of the overproduction strategy if it abates at all http://www.unz.com/isteve/the-worlds-most-important-graph/

if this population surge then expands beyond it's historical borders and causes mass societal disruption on a neighboring continent whose civilization has historically contributed great innovation and wealth to the world at large, and subsequently, said wealth and innovation contribution declines because of said societal disruption, do those who sought to eradicate the various diseases harbor some responsibility for the diminished prospects of the world at large?

Granted these are delicate questions but I believe their being asked has not just validity, but importance.

Certainly, simply ignoring pain, disease, and suffering is almost universally unpalatable.

But modifying one aspect of a complex system for what appears to be perfectly benevolent reasons, it is not at all surprising to find there could be downstream negative effects, negative enough to far outweigh whatever beneficent contribution you thought you were initially making. How do you make value judgments in such cases?

Gates himself has said it is far better to help people where they are regarding the recent unauthorized population influx events in Europe.

So I don't believe he is entirely blind to these potential downstream catastrophic effects.

Shouldn't this example of randomness still be pushed to the installation stage, instead of in the distribution. If Debian's binary package contains a "random" key, then we have a pretty large herd already using it.

Despite understanding and largely agreeing with the concerns against AMP Cache that get discussed any time an AMP article gets posted on HN, I cannot stress enough on how relieved I feel to see the lightning icon next to a mobile search result, especially on my now aging phone.

Most content websites have become such a massive crapfest of ad-bloat, bad UX, huge page sizes and general usability hell that it's nigh impossible that I'd be able to reach the actual content of a non AMP site in the first 5-10 seconds of clicking on its link. (On my phone that's an additional 1-2 seconds for registering the tap, and 1-2 seconds for navigating to the browser)

My click-throughs to non AMP websites have reduced considerably.

So say what you may, AMP (or FB Instant or its ilk) will prosper until the mobile web experience stops being so crappy.

(Edit: About a decade ago, when mobile browsers were in their infancy and data plans were slow and limited, I distinctly remember using Opera Mini for mobile browsing because it used to pre-render pages on the server and send a very light payload to the phone. This saved you both data costs and made mobile browsing even realistically possible)

Breaking down a few of the concerns in this article:

> With AMP [chat applications] cannot be used

True currently. There are no chat application amp extensions, yet. This could change in the future. Vendors interested in implementing one for AMP should get involved at http://github.com/ampproject/amphtml

> AMP does not have any markup specific to checkouts

Most web pages move from shopping cart to payment by changing URLs. This would work just fine with an AMP page. There is in fact at least one vendor who has integrated payments with AMP already: https://www.ampproject.org/docs/reference/components/amp-acc...

Also take a look at https://ampbyexample.com/advanced/payments_in_amp/

> AMP does not allow for use of forms

See https://www.ampproject.org/docs/reference/components/amp-for...

> They really do not support a logged in state, or user preferences. Things like recommended products, or recently viewed products will not work with an AMP page. None of the personalization aspects like Hi, Lesley are done with AMP.

See the (perhaps poorly named) https://www.ampproject.org/docs/reference/components/amp-lis... This supports loading content specific to the user, even on a cached amp document.

> if search and filtering are a large part of your sites mobile navigation, AMP will be useless.

This is exactly what amp-bind was built for:https://ampbyexample.com/components/amp-bind/

> Google Analytics is not supported on AMP

Google Analytics is fully supported in AMP. Here's the Google Analytics support page:https://developers.google.com/analytics/devguides/collection...

> If you use a different suite of tracking such as Piwik or kissmetrics, they will not work with AMP.

There is a large list of analytics vendors that have direct support here:https://www.ampproject.org/docs/guides/analytics/analytics-v...

Other vendors can be added with a small amount of configuration. Here's a guide for Piwik, for example: https://www.elftronix.com/guide-to-using-piwik-analytics-wit...

Alternatively, vendors can submit a configuration to the AMP project which is just a few lines of JSON, then the vendor will be supported more directly.

> Ad Revenue is Decreased

The link is to a single article from a year ago. There are many studies pointing to the opposite effect as well.

> A/B testing is not supported

See https://www.ampproject.org/docs/reference/components/amp-exp...

> Performance

I'm not sure what URLs the author used, but I tried to find a similar overstock recliner page that might be the right one. I found:

https://www.overstock.com/Home-Garden/Recliners/Leather,/mat...

The author tries to use a google.com/amp URL, but these redirect when not coming from a search click. Much easier is to take the CDN amp URL, which is served the same way:

https://cdn.ampproject.org/c/s/www.overstock.com/Home-Garden...

I loaded both of these in Chrome, simulated a mobile device, network tab, and throttling with Fast 3G. Here were my results:

* non-AMP: 42 requests, 1.1 MB transferred, Finish: 10.3s, DomContentLoad: 3.38s, Load: 9.52s

* AMP: 35 requests, 408 KB transferred, Finish 5.87s, DomContentLoaded 1.28s, Load: 5.88s

The AMP page is 60% smaller and hits the load event in 40% less time. However "loaded" is a funny term in the world of javascript driven websites and needs to be looked at more carefully.

I suspect that the author's referenced tool is reporting "fully loaded time" as the time that the last network event ended. AMP pages intentionally delay loading images below the fold to prioritize visible content. This results in some images loading later without impacting the user experience. For example, as I scrolled in the AMP page, the "Finish" time would move ahead to a new time as new images were loaded. With events like analytics triggers, looking at the time the last network event finished is typically a misleading metric and won't work correctly with most amp documents.

If you load filmstrips in Chrome's Performance Tab, you can see this more clearly. Filmstrips display what the page looked like at snapshots in time after loading starts. For my quick test with network throttling, the non-AMP page takes a little over 6s to finish reaching it's final state and the AMP page takes about 2.2s. So AMP here is nearly 3x faster as the user would perceive it on similar connection speed.

Conceptually I hate AMP. I wish they would just have guidelines for fast load times, and award better rank and a lightening badge next to pages that are adhering to those guidelines. I HATE that Google restricts design, re-formats pages, and serves your content.

That said, AMP clearly isn't for eCommerce. You want dynamic, personalized content for eCommerce. Recommendations based on past pages visited, or search terms, or your location... It's not just about fast loading pages.

Some eCommerce may fear that their sales will suffer if someone else gets a page that's in AMP and then Google's new rankings put that page over their own... But that's no reason to convert your site to AMP. It's a good reason to build out landing pages specific for search terms, do paid advertising around keywords, and just generally market your products / site.

Generally speaking, people who come in to product pages straight from Google are just doing price comparison anyway -- it's just a step in the decision journey, but if you've done a proper job of marketing your business, customers that buy tend to go straight to your site and do a search using your own search tools.

So, to avoid having to argue the same problems always again, heres a summary of some of the technical and antitrust issues with AMP:

1. You have to embed the AMP version from Googles servers, you cant self-host the AMP js, or run it from another CDN. This makes your site unavailable in, for example, China, relies on Googles systems, and ensures that Google knows every user of your site.

Source: https://www.ampproject.org/docs/reference/spec#required-mark...

> contain a <script async src="https://cdn.ampproject.org/v0.js"></script> tag inside their head tag.

2. You need to allow Google to cache the content, and all Google products will always link to the Google cache version. You can not opt out of this. You can not ensure users visit your own CDN version. You can not prevent Google from displaying modified versions of the pages (for example, the header UI of AMP pages in Google search, and the swiping between pages gesture).

Source: https://developers.google.com/amp/cache/faq

> Q: Can I stop content from being cached?

> A: No. By using the AMP format, content producers are making the content in AMP files available to be cached by third parties. For example, Google products use the Google AMP Cache to serve AMP content as fast as possible.

3. Pages that use AMP get a massive indirect ranking boost. Yes, they dont get directly boosted, but they get added to the AMP carousel, between the ads and the #1 result, or between the #1 and #2 result. If, for a given search term, none of the top pages have an AMP result, Google will boost the first 3-4 pages that have an AMP result to this place even if theyd organically rank on page 10 or later. In some situations, Ive seen results from page 13 boosted to #1.

This is ridiculous, Google just wants to restrict other ad networks' JS and recreates HTML/CSS/JS for no real reason.

APIs as infrastructure: future-proofing Stripe with versioning stripe.com

organsnyder 1 day ago 4 replies      
I work on a SOA team at a large healthcare enterprise. We currently write mostly SOAP APIs (yeah, I know, 2017 and all that...), and follow a typical pattern as what Stripe describes: Whenever we do a version bump (which is extremely frequent, since a WSDL breaks a contract the moment you sneeze at it), we create an XSLT transform from the new version back to the old. So if you're calling version 2, but the current version is 10, there will be transforms back for 10->9, 9->8, 8->7... all the way back to 2. It works well enough.

We're in the early stages of deploying a new RESTful stack, and versioning is a hot topic (along with getting people out of the RPC mindset and into a resource-based paradigm). While version bumps should be much less common, we'll probably end up doing something similar to our cascading transformations. Essentially, the old version becomes a consumer of the new version, and as long as the new version continues to hold to its API contract, everything should work with minimal fuss. Of course, that's assuming that we don't change the behavior of a service in ways that aren't explicitly defined in the API contract...

- https://news.ycombinator.com/item?id=13708927

It sounds like their YAML system has changed to be implemented in code instead, which maybe allows the transforms to be a bit more helpful/encapsulated. If anyone from Stripe is here, it would be awesome to know if that's true and why the switch?

I'm working on designing an API now that is based on Stripe's previous post from how they do versioning.

In general, the concepts employed by Stripe really encourage better design choices. All changes, responses, request parameters, etc should be documented and then handled automatically by the system. We took this approach in our design, although we don't do it with an explicit "ChangeObject" like Stripe does; it's a great idea though.

Hoping to be able to put out a blog post once we start implementing the system and getting feedback on what works and doesn't work well.

One question is, over the years, wouldn't you add a lot of overhead to each request in transformation? Or do you have a policy where you expire versions that are more than 2 years old, etc? (skimmed through parts of the article so my apologies if you already answered this)

3. Change in datatype.

In the above three cases, we had to force users to upgrade their versions.

All I saw was dumb-ass posts, ignorant comments, the passive aggressiveness, the "look at me doing this really mundane thing, but please like my picture so I can feel validated", etc... feels like a mouse-cat race to see which of us has a better life or something. I honestly feel bad for how much time I spent there when I could apply that time to learn new things.

After more than 6 months without FB, here's what I've learned:

- I still keep in touch with my closest friends, we chat on slack/iMessage every day. It's actually a good way to know who really misses you, during this time, only about 5% of my FB friends reached out to me through message or phone to ask how were things in life. The other 95%, I really don't even remember most of their names anymore. Just ask yourselves, why do we have to share so much of our lives with so many "friends"? I know we can filter, and create groups, etc.. but damn...do you really want to spend your life "managing" relationships, to see who sees what? I find that tiresome.

- I don't feel left out of anything, because I keep track of local events using other sources, I read news from faithful websites, and if I need to share anything I just use the old email or show face-to-face any pictures I need of my latest vacation from my phone without having to share anything with anyone.

- I gain more time, less stress, I don't feel overwhelmed to keep track of every social media update. I just don't care. If something important happens I will know it sooner or later.

- I no longer have this need to constantly keep posting photos of what I'm doing outdoors or whatever. I don't have the need to feel validated by anyone but myself.

- But most importantly, I regained my privacy, or at least my social footprint is bare none at this point. I'm using uBlock, Firefox, DuckDuckGo and other tools to keep trackers at bay.

I may never completely win this war, but at least my habits aren't being recorded and feed to any ML algorithm.

I don't understand the problem, you can use Facebook for adding friends and messaging them and it's free. You can use Facebook Messenger, not use the app and use website for adding people and getting their information. The newsfeed there can be turned off or customised, if you do install the app, all notifications can be turned off. This is a good and free service, but if people don't know hot to use it, maybe there is a point in writing about it. Messages about deleting Facebook account seem counterproductive, because why throw away a good tool if you use it rarely and it's useful?

This is a questionable assertion. Giant tech companies like Oracle and IBM don't tend to expand in this way, they make acquisitions of smaller companies, and use them to enhance the platform capabilities of the larger product.

I'm sure Zuck will be delighted if the "bottom billion" do all sign up and use Facebook, but they're never going to be massively profitable accounts.

Imo the acquisitions of Instagram and WhatsApp show the way that Facebook will go - Instagram adds a new and lucrative ad format, a profitable user segment and a base for adding in ideas from other platforms, such as Snapchat. WhatsApp builds out Facebook's graph and can be mined for intel.

One of the biggest wins here is this little tidbit:

A lot of the chrome interface libs about at the moment require you to maintain your own instance of chrome/chromium and launch the headless server with your command line, or require a pre compiled version, that can quickly get out of date (https://github.com/adieuadieu/serverless-chrome/tree/master/...). Having this taken care of is a blessing.

This is great, but it's sobering to see how hard it is to get a nice, "complete" PDF screenshot out of a modern site.

Here's a quick hack: https://gist.github.com/rcarmo/cf698b52832d0ec356c147cf9c9ad...

I'm using The Verge for testing because it lazy loads images, and am being clumsy about the scrolling, but it mostly works - I can get 90% of the images to show on the finished PDF.

What I can't seem to get right, though, is creating a single-page PDF where the page height matches the document height perfectly - it always seems to be off by a bit, at least on this site (mine works fine, _sometimes_).

Anyone got an idea of why this is so?

The API looks nice and clean, but I'm puzzled by this from the FAQ:

Is this true? Do teams write unit tests but only test them in a single browser? With test runners like Karma and Testem, running tests concurrently in multiple browsers is easy. You'd be throwing away huge value if for some reason you only decided to test in one vendor's browser.

Current working professional and an OMSCS student here. It highly depends on the context. Biggest pros are:1. This is perhaps the cheapest Computer Science masters in the United States from a premier school. The degree is exactly the same as offered to the residential program and the credits acquired are all legit and transferable to other universities. I had friends who transferred from OMSCS to a regular school and skipped one full semester due to the credits earned.2. An OMSCS qualification holds way more water than if you do random MOOC qualifications on Coursera and others.3. The coursework is the same as the residential program. So if you dont believe in studying an MS at all, then this program is nothing special. Its a Masters in Computer Science. So It's pros and cons are the same as a regular MS.4. If you are international, then having an OMSCS degree is equivalent to having a Gatech MS degree. It is a superb add-on to your profile and also qualifies you as a graduate level tech specialist for future Visa processing.5. If you are international and looking to stay and work in your own country, then your mileage may vary depending on your circumstances. OMSCS provides no visa support and no career counselling. It does have an online portal for jobs but its more geared towards residents.6. Other than that, it forces you to think and study new areas of research while you work so its extremely enriching.7. The program is more or less extremely well run with regular assignments, proctored exams, 1-1 sessions with professors and what not.8. Some companies reimburse your tuition, so its virtually free (at least for me)

Cmon guys, a US Masters for 7000 USD? Are you kidding me? Its totally worth it. In fact I feel blessed that such a thing even exists. GaTech has been a trailblazer in this regards.

Worth it -- based on what metric?

My wife did an online master's degree (at a legit university that also had an online program). You have to be very good at self-pacing, diligence, and learning autonomously. You have to be so good at it, in fact, that the type of person who would succeed in an online master's program is the same type of person who would succeed in self-learning without the master's program.

So if your only goal is to learn, then I say no, it's not worth it.

However, you're in Brazil and not a lifelong programmer. Credentials may work against you if seeking a job in the US. Many US companies look at South America as the "nearshore" talent, much better in quality than devfarms in India, but also still cheaper and -- because of that -- slightly lower in quality than US talent.

In that case, spending $7k and completing the program and getting the degree may help you get a $7k higher salary in your first (or next) job. It may give US companies more confidence in your abilities, as you received a US graduate school education.

So from a financial perspective and the perspective of job opportunities inside the US as a foreigner, then I think it may be worth it. If you don't care about getting US jobs then still probably not worth it.

Best of luck!

At 5K, the price is right (my in-person master's was 22K, although my employers covered most of it) but be aware it's not the missing piece to catapult you into superstar developer earning 170K/year.

Honestly I think your time is better spent working on real projects. In my CS master's program I met many students with no real-world experience. One was a paralegal before school, and after he graduated he became...a paralegal with a CS master's. Experience > degrees, every time.

There's value in the program (algorithms and data structures being the most applicable), but just go in with your eyes open knowing that the degree is not a glass slipper that'll turn you into Cinderella overnight. Too many IMHO falsely believed my program was a jobs program and really struggled to find work in the field.

If you can do it at night while working FT, great but don't take 1-2 years off work. It sounds appealing to be done ASAP but you're unlikely to make up that 60-120K/year in lost wages. Unless you're fabulously wealthy.

Good luck.

Logging in as a throwaway. The program only costs $5k but it was one of the most expensive things I've done in my life.

Got a job at Google directly because of this program (a few classes like CCA helped a lot with interviews). I'm aware of at least a couple dozen of us from OMS here.

The program cost me dearly. It cost me my relationship with the SO and it cost me my health (staying up late nights, lots of coffee).

* $5k cheap, it's nothing, the real way you pay for it is via your time.

* The teachers like the flexibility as much as we do. Many are top notch. I took two classes from professors that work at Google (Dr. Starner and Dr. Essa), one at Netflix (Dr. Lebanon), and a few others have their own startups.

* One of the classes was taught by Sebastian Thrun, with a TA at Google, but I think that's changed now.

* The lectures are good, but you have infinite ability to subsidize them with Udacity, Coursera etc.

* You learn squat by watching videos. The true learning happens at 2am when you are trying to implement something, and end up tinkering, debugging, etc. That's when things click.

* The hidden gem is Piazza and some of the amazing classmates that help you out. Lots of classmates that work in industry and can explain things a lot better. I.e: Actual data scientists and CTOs of Data Science companies taking the data science class. They were amazing and I owe my degree to them in part.

* Working full time and taking classes is not easy. Consider quitting and doing it peacefully.

* From within Google, I've heard from people that did the Stanford SCPD (I'm considering it) and also OMSCS. Lots of people that say the SCPD program wasn't worth the time and effort. No one yet that's said the same about the GT program.

I've heard from people that have done the program in-person, and they say the online lectures and materials are significantly better.

I'm halfway through the OMSCS in the machine learning specialization. It has been a great experience so far and definitely worth it for me.

A couple of things to consider: As you mentioned, it is more focused on Computer Science than Software Engineering/Development. There are a couple of Software Engineering/Architecture/Testing courses but I haven't taken them so I can't comment on how relevant I think they are to my day job.

It's an incredible bargain... 7-8K for an MS (not an online MS) from a top 10 school in CS. That on it's own makes it worth it for me.

It's not easy and it's not like a typical Coursera/Udacity course. Depending on which courses you take it can be quite challenging (which is a good thing). You typically don't have much interaction with the Professors but there are a lot of TAs and other students to help you along the way.

I have finished the OMSCS program and in some ways I have mixed feelings about it. My background has been primarily in mathematics/statistics and I didn't come from a "tradition CS" educational background.

Did I learn a lot?

I learnt a ridiculous amount. For the time+dollar investment it is amazing. The program is definitely not easy either.

It has been amazing to learn the concepts in ML (Dr. Isbell) and AI (Dr Starner) courses and then a few weeks later think "I think I can actually use these concepts in my workplace".

Why the mixed feelings?

Not all courses had the same quality to it. From the top of my head, AI, ML were probably the best 2 courses. Other well ran courses I would add was computational photography, edutech, introduction to infosec (besides the rote learning...), however some of the other courses I had a relatively negative experience.

The degree does suck up a lot of time and I would say it is the real deal.

Knowing what I know now I can't say 100% that I will "re-do" OMSCS - to be fair on GaTech I'm not sure whether the challenges that I feel above are due to an online program and I personally would be more suited to an in-person program but the experience has definitely been better than Udacity's nanodegree and any MOOC which I have sat.

Overall I would say if you do it for the sake of learning and that alone - OMSCS is worth it. For any other reason please don't do it.

As someone currently in the program and graduating this Spring, I have found this program to be incredibly rewarding.

It has been fantastic in my career development as well, allowing me to land a job in ML before I have graduated.

The program does have its hiccups here and there. Some courses have been reported as being poorly organized, but this is certainly the minority. Also, you may not receive as much individual attention as you would in a on-campus program. This is aided by the fantastic community of students in the OMSCS program which provide a support system for each other through online forums/chat. If you are not much of a self-starter and need specific guidance, this program may not be for you.

If you haven't been working as a software developer long and you don't have a background in CS, it's going to be difficult.

I'm about halfway through and many of the classes assume that you have the equivalent of an undergrad CS degree. It's not intended to replace an undergrad degree.

That doesn't mean you can't do it, but your going to spend a lot of time catching up. From what I've seen, the students without a CS degree, even those with significant industry experience, have had a much harder time with the more theoretical classes.

It's also a graduate program, and the classes are pretty rigorous compared to what I did in my undergrad CS degree.

Also keep in mind that admission is fairly competitive. And admission is only probationary. You have to complete 2 foundational classes with a B to be fully accepted.

I've completed the majority of the OMCS program. My specialization is 'Computing Systems'. I have a 4.0 GPA so far. I did not do CS as an undergraduate, but I've been programming since I was very young.

Here are my thoughts on what people need to succeed as an OMCS student:

 * Be able to program in C, C++, Python and Java at an intermediate level. And, know one of these very well. * Be able to use a debugger (GDB) and valgrind. * Be able to administer and configure Linux systems. * Understand data structures and examples (std::set in C++ is RB Tree backed, std::unordered_set is hash table backed) * Understand basic networking concepts and key technologies (TCP, UDP, IP, switching, routing, etc.). * Understand the x86 computer in general.
Finally, I think some of the classes are meant to weed students out. People may think that 'Intro to Graduate Operating Systems' would be an easy first course for CS beginners. It's not (unless they've changed it). It was primarily about writing multi-threaded clients, servers, caches and proxies in C, using shared memory (IPC, POSIX Shared Memory) and various other C/thread projects until you become a half-way decent C programmer. They deduct points for working code that has any errors (memory leaks, etc.) too. So don't be surprised if a seemingly easy OMCS course turns into... I had no idea. I'm going to have to drop this course. I saw that happen to several students.

I've done well so far, but I have the programming/logic background to do the work. If you don't, brush up on the skills listed above before enrolling.

Edit: The class projects are a lot of work. Be prepared to give-up your weekends and evenings. Even if you know the material and the language, it's a job to get through some of the projects.

I have been doing this for 2 years now. I enjoy this program. There are many students who are taking Gatech OMSCS and also taken MOOCs from Coursera, Udacity, and EDX. The defining characteristic of good students taking this course is, they are all self-learners, independent, and they want to learn Computer Science without giving up on the current full-time job. I have been keeping notes for the all the subjects that I have taken: http://www.coursedocs.org/gatech/index.html - Have a look at it to get a glimpse of the course work involved.

Cons: I've noticed some students who come to get their MS degree from a reputed institution because it is cheap. Due to coursework pressure, they take short-cuts, like doing group-work, discussing solutions when you are prohibited, plagiarizing in assignments, etc.

> I believe this program is a good complementary source of knowledge to become a better software developer.

That's something you could learn on your own. But your knowledge of "technologies" are more valuable to employers than CS degree - especially if you have work experience.

The tech industry isn't like academia ( economics ) where you have to build up credentials. Work on projects that deal with web technologies or even better learn the back end ( databases ) or even the middle tier/server code if you are a front-end developer.

Becoming a full-stack ( front-end, middle-tier and especially back-end ) is going to be far more important to employers than if you know what undecidability is or computational theory.

Degrees are very important if you want to break into the industry ( especially top tier corporations ). But if you are already work in the industry, employers want to see the technologies you are competent in.

If your employer is willing to pay for it and you have free time, then go for it. Learning is always a good thing. But if you want to further your career, go learn SQL ( any flavor ) and RDBMs technologies - SQL Server, Postgres, etc ( any you want but I recommend SQL Server Developer Edition if you are beginner on Windows OS as it is very beginner friendly from installation to client tools ).

A full-stack web developer is rare and you could even sell yourself as an architect/management. That's a difference from being a $60K web developer and a $200K full stack developer/architect.

Only a few data points as an outside observer, but...

1 - The people I've seen doing it are learning A LOT - more than another online program I've seen.

2 - They're also working A LOT - it intrudes on all aspects of their personal life. It's as much or more work than doing an in person CS degree.

3 - The folks I know don't have CS undergrads, which also makes it more difficult.

Net - it can be worth it if you missed CS as an undergrad, but you'll have to work. You need to ask if there are enough people in Brazil who value the credential (or implied skills) to make it worth the time. The time investment is more expensive than the $s. (It will be thousands of hours)

I'm considering the OMSCS because it would be the cheapest way to add credentials to my resume and because I'd rather not go back for a second bachelor's. (I don't mean to sound cynical--I'm interested in the subject matter, of course, but you can get all of that without going through a degree program.) Exchanging $7k for more legitimacy in the eyes of prospective employers is the main appeal of a formalized program. Does anyone have any experience with or thoughts on the signaling potential of the degree?

It really depends on where you are in your career. The GT MSCS is very well regarded, so it's an excellent credential - but frankly the education is quite haphazard and I don't see that improving any time in the future. Teaching quality varies highly, from great to excretable - for many classes, the model is "a little lecture, then lots of poorly-curated assignments". This consumes a lot of time, in a very inefficient manner. Yes, you will learn, but mostly by through your own effort. The very high workload is really not suitable for a professional MS program, where it has to be managed with a job. I find class workload expands without bound every semester and even one class will significantly impact career and relationships. There is no force causing workload to be decline, so I expect that the program is rapidly going to become dominated by early-career full-time MS students, in the U.S. and outside, who live with their parents and knock out an inexpensive, high-quality MS CS. For those students, it's a great choice. If you don't fit that profile, it's a poor professional choice. If you have the discipline to teach yourself via MOOC classes, you will get a better education delivered much more efficiently - but that doesn't carry the credential. So in short - if you need the credential and can devote full time, it's an excellent choice. If not, I do not suggest it.

I've been entertaining the idea of going through this course as well. I graduated 2 years ago, BS in CS, and part of me misses being in school. Plus my employer has a decent tuition reimbursement program.

Would anyone who works full time and gone through this program care to share their thoughts?

Working pro with 12 years experience. Absolutely not worth it. Most of your classmates will have not coded before.

The classes are cheap. The hours are long. In the end your grade depends on teammates who haven't been vetted. Three teammates who can't code? You get a C and don't pass.

Course content is extremely dated. UML and SDLC paradigms from the 70's with xerox pdfs distributed to "learn" from.

This is a money grab.

Not to be harsh, but you probably won't get accepted. You'll need to do some CS nanodegrees first, or something equivalent (a full undergrad CS/maths degree is obviously ideal). I know people in similar positions, even one with a physics degree, who could not get in due to lack of academic experience.

Otherwise, I think OMSCS is totally worth it. It is hard though. Really hard. I have a family, significant engineering experience, and I find the workload intense. It puts pressure on my family at the same time because I'm not available as much. So I'm taking it very slow, no more than 2-3 courses a year.

It feels great to be 'back at school' after so many years. I love learning new stuff and the challenges of hacking away at low level things. The kind of thing you rarely get to do professionally unless you're very lucky (or not getting paid much). Almost makes me wish I had done a Ph.D.

I don't know if it will help me get a better job or whatever, but it definitely fulfills my own internal itch.

I have a regular old masters in CS from GT. It's probably worth it from a career standpoint (if nothing else it signals that you care about self-improvement and take active steps to doing it). I would expect you'd miss some of the 'grad school experience' (for better or worse) and networking opportunities. The actual content itself can probably be gotten for free from other courses on the web if you take a syllabus from a CS dept to get an overall program. That path wouldn't have the benefit of access to teachers and would require a lot of discipline.

I don't know how it would be looked at in Brazil or what the economic cost/benefit are in terms of your own income. I did know a few folks from the University of Sao Paulo that did grad and postdoc work while I was at GT though, so clearly some people are aware of GT in Brazil. That might be another avenue to get opinions from. I would be interested to hear how the costs compare to an institution that was local to you.

As a secondary question, for those who did complete the program, what was the general time commitment per (semester or class) vs. how long you were in the program? I see that you must take 2 classes in the first year, but didn't see any other further requirements on speed of completion.

edit: Answered my own question - You can't have two consecutive semesters "off"[1]. I.e. the slowest possible pace would be 2 classes in the first year, then 1 class every other semester. So I suppose it would be:spring/summer 'xx: 6 credits, 24 remaining, spring 'xx + 1: 9 credits, fall 'xx +1 : 12 creditsetc.

I'm speaking from my past experience as a hiring manager at a start up with outlier standards for performance and trajectory in software engineering and machine learning. I estimate I've screened tens of thousands of resumes and interviewed at least a thousand people in my career.

First and most important: your internships and work experience, and what you accomplished during those jobs. They should tell a story of increasing and accelerating personal growth, learning, challenge and passion. If you can share personal or class projects, even better.

After your experiences, your degrees will be considered based on the number of years each typically requires, with early graduation and multiple majors being notable.

 1. PhD, if you have one. A STEM PhD was particularly helpful for ML/Data science positions, but not required. 2. BS/BA (3-4 year degree) 3. MS/MEng (1-2 year degree)
Put another way, if you don't have a PhD, the MS/MEng program is a tiebreaker compared to your experience and undergrad credentials.

International students get a raw deal. The online masters will barely help you get a job or launch a career in the US. US universities appear to offer the chance to work for major US companies with a notable university (such as Georgia Tech) on your resume, only to feed their graduates into our broken immigration and work authorization system, H1-B indentured servitude and no replies from the countless companies that have an unspoken higher bar for those needing sponsorship.

To round out a few other contexts HN readers might experience:

If you are an international considering an on-campus MS/MEng, US universities are charging full price while giving you a credential of limited value and utility. Apply the same comments above but at a much higher price than GA Techs OMSCS.

If you are completing/just completed a less notable undergrad degree, paying for a masters program at an elite CS school (like GA Tech) is usually a bad deal. If it not a requirement for the positions you seek, it won't help your career chances much.

If you have an undergrad degree and your employer will pay/cover your MS/MEng at night/personal time (and that is your passion), awesome and go for it! It will be a lot of work and lost sleep to get everything out of the experience, but a lifelong investment in your growth and experience.

If you are completing/just completed a notable undergrad degree (tier-1, internationally recognized program), you don't need the masters. Feel free to get one for your learning, sense of self and building research connections while you ponder getting a PhD. The hiring and salary benefit will be very small--you are already the candidate every company wants to meet. If you decide to get a PhD, that will open some new doors but take 5+ years to get there.

At my previous company, we made it our forte and team passion to get authorization for employees--given a global pool of candidates and a hiring bar to match. I'm really proud of our effort here given the broken and unfair system. Sadly, many companies do not share this value or cannot justify the time, effort and expense, or cannot scale such a program to a larger number of employees across a less selective bar.

If you like Proton features and want to move away from Gmail, consider Mailpile[1]. It's almost ready, there's a release candidate and packages for Debian/Ubuntu; it offers to protect your data with a master password like Proton; it supports GPG which with all its problems is still the way to encrypt your emails; and you can run it on your own server. Best of all it's open source and written in Python. You can know exactly what it does with your messages.

Mailpile is an email client (MUA) so you will need a server (MTA). At first you can try it out with your regular ISP, even Gmail. Later you can set up your own server. Setup is a little involved but much less than people tell you and, if you choose a competently run distro, requires very little ongoing maintenance.

With your own server, you can have it working exactly as you like. Export feature? No problem, you have direct access to the maildir, mailbox or the database. Want a catch-all? One switch in the config. You will have little trouble finding a provider who accepts your preferred method of payment, too.

Love to see more Kubernetes success stories.

I work for an ISP and we are trying to write another success story ;) As an ISP, we have tons of constraints in terms of infrastructure. We're not allowed to use any public cloud services. At the same time, the in-house infrastructure is either too limited, or managed via spreadsheets by a bunch of dysfunctional teams.

For my team, Kubernetes has been truly a life saver when it comes to deploying applications. We're still working on making our cluster production-ready, but we're getting there very fast. Some people are already queuing up to get to deploy their applications on Kubernetes :D

What I especially love about Kubernetes is how solid the different concepts are and how they make you think differently about (distributed) systems.

It sure takes a lot of time to truly grasp it, and even more so to be confident managing and deploying it as Ops / SRE. But once you get it, it starts to feel like second nature.

Plus the benefits, in almost any possible way, are huge.

Really exciting stuff, happy to see the Github team launch this.

Kubernetes is becoming the goto for folks needing both their own physical metal presence and cloud footprint too. And the magic of Kubernetes is that it has APIs that can actually give teams the confidence to run and reuse deployment strategies in all environments. Even across clouds.

If you are like Github and want to use Kubernetes across clouds (AWS, Azure, etc) & bare metal and do deploy/customize that infra using Terraform checkout CoreOS Tectonic[1]. It also tackles more of the subtle things that aren't covered in this article like cluster management, LDAP/SAML authentication, user authorization, etc.

How hard (and how realistic) it is to actually get a reasonable understanding (and then stay up-to-date) with Kubernetes internals? Is there any go-to reading material?

We had ran another large-footprint container management system (not K8s, but also popular), and when its DNS component started to eat all the CPU on all nodes, best I was able to do fast,was just scrapping the whole thing and quickly replacing it with some quick-and-dirty Compose files and manual networking. At least, we were back to normal in an hour or so. Obvious steps (recreating nodes) failed, logs looked perfectly normal, quick strace/ltrace gave no insights, and trying to debug the problem in detail would've taken more time.

But that was only possible because all we ran was small 2.5-node system, not even a proper full HA or anything. And it had resembled Compose close enough.

Since then I'm really wary about using larger black boxes for critical parts. Just Linux kernel and Docker can bring enough headache, and K8s on top of this looks terrifying. Simplicity has value. GitHub can afford to deal with a lot of complexity, but a tiny startup probably can't.

Or am I just unnecessarily scaring myself?

Would love to hear more about this was accomplished. I'm currently exploring a similar issue (pulling per-namespace Vault secrets into a cluster). From what I've found, it looks like more robust secrets management is scheduled for the next few k8s releases, but in the meantime have been thinking about a custom solution that would poll Vault and update secrets in k8s when necessary.

I'd be interested in hearing what kind of autoscaling system they use for their Ruby pods.

We're running a few (legacy we're moving to Go) Ruby apps in production on Kubernetes. We're using Puma, which is very similar to Unicorn, and it's unclear what the optimal strategy here is. I've not benchmarked this in any systematic way.

For example, in theory you could make a single deployment run a single Unicorn worker, then set resources:requests:cpu and resources:limits:cpu both to 1.0, and then add a horizontal pod autoscaler that's set to scale the deployment up on, say, 80% CPU.

But that gives you terrible request rates, and will be choking long before it's reaching 80% CPU. So it's better to give it, say, 4 workers. At the same time, it's counter-productive to allocate it 4 CPUs, because Ruby will generally not be able to utilize them fully. At the same time, more workers mean a lot more memory usage, obviously.

I did some quick benchmarking, and found I could give them 4 workers but still constrain to 1 CPU, and that would still give me a decent qps.

Author here with just a quick note that writing this was a pretty great learning experience. Postgres has always been the ultimate black box it does some amazing things, but I generally have no idea how.

I read a lot of Postgres code to get this finished, and I'm happy to say that for a codebase with so many authors, the quality of Postgres' is very high. Like any complex program it can be a little hard to trace through, but most of the naming is pretty self-explanatory, and it comes with some really amazing comments that walk you through the high-level design. I'd definitely recommend taking a look if anyone is curious.

Thank you for the article, but I do have one quibble:

As much as I like Postgres, I also like SQLite, which uses a simple file lock and yet is utterly acidic (https://www.sqlite.org/transactional.html). From SQLite's FAQ:

 > SQLite allows multiple processes to have the database file > open at once, and for multiple processes to read the database > at once.

"Every transaction in the database is applied in serial order, with a global lock ensuring that only one is being confirmed committed or aborted at a time." Is this true? I assumed you could transact in parallel, if there was no conflict, e.g. different tables were involved or maybe even different rows.

Postgres is entirely designed around the idea of durability, which dictates that even in extreme events like a crash or power loss, committed transactions should stay committed.

Although if I had a $100 for every time I've had DB corruption in Postgres over the years...

That being said, since 9.4 (or maybe 9.5) these incidents have mostly stopped happening and it's been remarkably stable.

My brother was diagnosed with a rare form of sarcoma (cancer) at age 35. Basically was given about a 10% to live. 180 servings of chemo/radiation later we started lining up hospice and he prepared to say goodbye to his 2 young kids and wife.

Last ditch effort was an experimental drug. Out of 150 people in the trial, he's the only one alive 12 years later. 6 years ago he started a company that is about to hit 8 figures in revenue and over 300 employees.

With much sensitivity to the physical and emotional turmoil the author must be experiencing right now, I disagree with his advice:

> Stop just assuming you have a full lifetime to do whatever it is you dream of doing.

Rare and catastrophic events like this that can severely shorten your life are ones you should not plan for. If they occur, that's very unfortunate, and maybe you'll still have a contingency plan that can rearrange your plans to fit the remainder of your life, but he was still right to have arranged his life from the start to maximize his expected (in the statistical sense) impact:

> Before this diagnosis Id been thinking of my 1st 35 yearsaside from being a ton of fun and travelas preparation. I felt like I was building a platform (savings, networks, skills, experience) that I could then use in my second act to make a real contribution, to make my mark

"Most of the time", he would have been right to use the early part of his life to make long-term investments in his development. It's just that this time it turned out to be the wrong choice.

PSA for anyone reading this: Colorectal cancer for younger people seems to be on the rise. They don't seem to know why.

My father had colon cancer and was not expected to survive it. I think he was 69 when he was finally diagnosed. He had put off seeing a doctor because he thought it was "just old age" and it was quite advanced by the time he was diagnosed. He did survive it and died, iirc, just short of his 89th or 90th birthday.

A lot of my relatives have had cancer, some of them more than once. Few of them have died from it. So, I tend to be biased in assuming that it can be conquered, even when the doctors say the odds are long against.

I know I have seen quotes on HN about how the odds are long against startups and other things, but how you can work to overcome those odds. I think it is a bit like that.

Good luck in your journey. Best wishes on your outcome.

Remember that the anecdotes on here serve two purposes.

(i) to show that the aggregate does not inform the individual. As a species we are too influenced by aggregate stats. There is huge variation in individual responses.

(ii) history is written by the winners. Those people who did not survive cancer are not here to write about it and those surrounding them tend to want to forget and move on. Survivor bias is a real thing.

Not only is this story a reminder that life is short, but also that we must battle each day to keep perspective when the world and our human limitations are always trying to skew our views.

Given the tensions in the world, seeing things from the other points of view has never been more important.

The doctor is likely to recommend a colonoscopy. Removal of polyps (a likely source of bleeding) reduces the chances of cancer developing and can only be done during a colonoscopy.

Thankfully ALL has a very high success rate for treatment and long term survival, but it has certainly made me realize how unpredictable life can be. I was putting things off that I wanted to do with my life and once I finish recovering, I certainly will work to correct that.

Do your research. I'm not an expert, not even close, but a buddy of mine pushed his wife's curve way, way out. Maybe you can too.

She has stage 4 lung cancer, it's spread to her brain. If she gone to Stanford, like she wanted, they would have done whole brain radiation to try and blast the brain tumors. The problem with brain tumors is that there is that barrier that keeps bad stuff out of the brain and it only lets small stuff through, chemo tends to be large.

My buddy started researching and asking questions (he's business/sales but I think he's an engineer). The 5 year survival rate is less than 1% for stage 4 lung cancer. So he started asking doctors and hospitals "what's your 5 year survival rate". Everyone pointed him to national stats and he said "no, I know those numbers, what are yours?". El Camino Hospital publishes their numbers because they are much, much better: 15%. I know, 15% isn't great but it is a boat load better than under 1%.

So they went there. El Camino has a different approach to this sort of situation, they use some chemo (avastin maybe?) that is small celled and gets through the brain barrier. They also did pin point radiation.

The results: it's 2 years out, I think 2 years and 1 month, and my buddy's wife isn't fine but she's damn close. She's on an every 3 week chemo cycle, she typically gets 11 good days and 10 crappy-bad days. They both retired (I still pay his health insurance which is a big deal) and bought a travel trailer, do 2-5 days trips up and down California. They are fully aware that they are trying to cram all of their retirement into a few years and so far are doing a great job, their doctor loves it (apparently a lot of cancer patients sit on their butt, just waiting for the next chemo session).

If she had gone to Stanford, while the radiation would have likely wiped out the tumors, it also has this little side effect called dementia, happens very quickly. So this outcome is much, much better and it only happened because my buddy did his homework.

And one sort of cool thing happened: this all started before my company imploded and I gathered the team and said "I want to send Bob on vacation. We've only got so much runway left so if you don't want to use some of that money on Bob, I get it, I won't judge, I'll pay for the vacation myself." It was unanimous, they wanted the vacation to be from the team (I was so proud of them, that's the team I wanted). So we sent them back east to see the fall colors, they had a great time.

It's worth stating that I've watched my mother-in-law and my father die of cancer (and while my love for my dad is pretty obvious, I loved my mother-in-law as well, we got along great). The thing that I've learned is the second you know you have something that is life threatening do whatever you want to do RIGHT NOW. I pushed for the vacation thing for Bob because my mother-in-law didn't want to have friends over "until she was better". I deeply regret not just arranging to have all her friends come in. She died pretty quickly.

So I don't want to be morbid, or show any lack of hope, but there is the possibility that OP is in the best shape he's gonna be. So use that time to have some fun, build some memories, whatever you think is good. If you kick cancer's ass you'll have some memories to look back on, if you don't, your family will have some to hold onto. Do not listen to the doctors, they tend to be overly hopeful and give you a false sense of hope (I get it, it's kind of all they can do, but we would have liked a more realistic view. They let my mother-in-law think she was going back to work).

Good luck, cancer sucks.

Edit: explain that lots of patients don't live between chemo sessions and a typo.

Something I wish my parents had told me when I was growing up:

You, the thing listening to this advice, is just a small part of a greater whole, much of which you (the thing listening to this advice) are not consciously aware of. This is because you were built by your genes to be good mainly at one thing: reproducing. That's all your genes care about. They don't care about your happiness or achievements or having a fulfilled life. In fact, they don't even really "care" about reproducing, except the same way that water cares about flowing downhill.

Your negative emotions are real. The pain you feel is real. But it's not you. It's something that is being done to you. In that regard it is exactly the same as physical pain, which is also not part of you, but rather something done to you. The fact that you're depressed is no more a character flaw than the fact that it hurts when you skin your knee.

I'm gonna feel sad whatever I do, and I may as well make some time to give in to really feeling sad and getting it out of the way.

When I feel bad I generally do a quick mental checklist: Have I drunk any water lately? Have I eaten? Have I had my pills? Usually the answer to at least one of those is 'no' and I feel better after correcting them. Then since my need for a warm place to sleep is pretty well settled, it jumps up a few notches to checking when the last time I cuddled someone was, how I feel about my current project, etc.

How does one determine that someone is really "feeling bad about feeling bad" or whether they're satisfying some expectation of the experimenter or doing something else? And moreover, cause and effect can be slippery, maybe those with more extreme problems tend to be caused to do the thing the experimenter thinks is a mistake rather what they do having an effect.

This effect is at the root of homesickness, I think. In my experience you're never really homesick when you're happy - homesickness only happens when you're sad for some reason and you can't separate it from the place/situation you're in. That reason is only sometimes a direct result of that situation, but your instinctive response is to think "this would be better if I were at home" regardless.

Getting over homesickness seems to be about being able to accept the bad thoughts as you would do at home and move on, rather than "feeling bad about feeling bad" in the form of wishing you could just go home.

I'm fortunate enough to have never experienced it, but I imagine serious grieving is like this too.

It feels like a "duh" thing to me.

Emotions are adaptations. They trigger in particular circumstances and they cause particular behaviors. The entire point of having an emotion is to engage in emotionally appropriate behavior until the circumstance has passed. Positive emotions are attractors towards the triggering class of circumstances, while negative emotions are repellers.

"Feeling bad about feeling bad" pretty much works out to be something like "naive gradient descent on the function that maps attention onto emotional valence". This doesn't solve the underlying situations that cause you to feel bad - it's like not looking at pictures of your dead wife, rather than grieving, getting support from friends and family, and then moving on with your life.

This is very good news for Emscripten / WebAssembly developers. One of the main limitation in ASM.js / WASM based applications is a size of emulated HEAP. It has to be a contiguous memory block, what is so unlikely to allocate by browser (from my tests it's ~10% of users cannot allocate 256MB for HEAP). It's that due a memory fragmentation.

Having 64 bit by default fixes such problem. That's a good move. Well done moz://a

Bravo! This is overdue.

Back in the early 80's my dad ( a chess teacher from Odessa ) immigrated to NYC ( with just $150 ). My mom worked 3 jobs to put him through Yeshiva Uni where he learned Cobol, JCL, and Fortran.

He ended up getting hired right away by Lehman Bros, and realized he was sitting on a gold-mine. Tons of well-educated immigrants were coming onto the golden-paved shores, with 0 knowledge of computer programming.

So we upgraded our family 1.5 bdrm apt in Jackson Heights, Queens, to a modest 3 bedroom tower apt in Forest Hills, where he proceeded to lecture evening and weekend classes by the droves.. (all on 1 white board!) * my job ( i was 13 at the time ) was to serve everyone instant coffee and bagels.

One day I was curious and asked him Dad, these folks can barely speak english.. how are they going to even pass their interviews? he looked up from his hand-drawn spreadsheet he kept a strict record of students..Oh that part is easy I already know all their future managers It was the perfect funnel.

best of luck fellas!

In the registration process:

Are you legally authorized to work in the United States?Just a note: We are currently unable to offer income-based repayment outside of the United States. You can still attend Lambda School, but you would have to pay at least $10,000 up-front

$10,000 - that's about as expensive as a high quality bachelor's degree (in Germany) at private university via distance learning, where someone can pay flexibly btw. Additionally: We are talking about 6 semesters worth of material and study, study time can be extended for free.

What you are offering is a 6-month crash course where someone will have _NO_ degree whatsoever afterwards. I also doubt how much computer science you can teach in that time. Normal CS curriculum spends about one module (one semester's worth) on just the introduction to programming, has probably 2 modules (that you would do in 2 semesters) of computer science basics like computer architecture et cetera... there are so many good resources already available, including lectures of incredibly professors from some of the greatest universities.

Also: You have to create the learning resources once and can take on as many students as you want w/out any additional cost, great for you, seems like selling snake oil to me. I am unsure besides the resources and apparently online group working ("group work happens live and interactive") what it is you provide for possibly 30k$ in cash? 1 success finances the cost you have w/ an incredible amount of failures, and it's not clear to me if that one guy finding a job will have done so bc of your awesome curriculum and support?

It seems to me like anyone who can possibly finance proper education some other way should (and I want to repeat: it's a 6-months crash course, not a degree)

I feel it's misleading, it's naming feels like its coat tailing off implying something like a university comp sci degree ( with a practical bent), and this seems more of a React web/mobile app design course with a bit of C++ and some basic algorithms ( presumably so they can pass interviews that seem to be obsessed with such things )

$30k seems steep, and while 0 $ upfront is appealing, that kind of strategy can be exploitative( like 0% deposit financing ). It can be super appealing to someone who doesn't have much money, but they end up paying a lot more than they really should be.

Not saying this is bad (maybe it's good thing), but when look through it, I'm getting alarm bells.

I also have questions about the quality of instruction. There are some big name institutions listed, but that doesn't necessarily indicate quality instruction. The best researchers are often emphatically not the best instructors, and for this venture instructors are much more important.

I sincerely hope this is successful; perhaps this can prompt traditional institutions to be more innovative (in delivery, instruction, finance, all of it).

I'm going to play devils advocate here. I don't think I'd be in your target market primarily because I feel for 15k a year I can achieve a decent education just by online resources alone. It would be just as well recognized; I'd even think that a local community college could be cheaper. Granted, upfront cash is a luxury that few without the bank of mom and dad can access.

An Irish degree costs 3000 euros a year to enroll. Even for four years that would be cheaper than what's on offer here with a world wide recognized qualification.

On the whole, it seems like a very American solution to an American problem, education is just far too expensive in the states. * I'm a beneficiary of free state education from Ireland.

Best of luck in the effort, I do applaud you for it especially in the US where there are always tech shortages but...I really wish your country was in a place where your type of business didn't have to exist. A country where only those who can afford to be educated can receive education. I'm saying this as someone living in Nepal where those who can't pay can't learn either.

I really wish education was subsidized, worldwide! Alas, never going to happen.

'austenallred is a cool individual, and this seems like it could be a particularly good take on the code school model, but I always wonder if programs like this help on the margin. That is, do they help people succeed (i.e. get a job in software) who otherwise wouldn't, or do they just accelerate the success of those who would, one way or another, eventually succeeded regardless of their participation in the program? I think the latter might be likely simply just because for good programs (like this one) demand far outstrips supply, so they can be extremely picky about who they accept and only accept individuals who are destined to succeed.

Not that accelerating the success of those destined to succeed is in any way a bad thing (it is, undoubtedly, a good thing, and can certainly make for a good business), but my interest is much more in helping those succeed who otherwise wouldn't. That seems like a much harder challenge and one that can have more interesting ramifications for things like social mobility and income inequality.

I've thought a bit about how you would structure something like this as a pro-bono service instead of a paid service. The thing I always struggle with is how to get people who currently lack the basic computer skills, math, and logic skills and get them to the point where they could benefit from a bootcamp. Most people I know who've made it through a bootcamp successfully already had some sort of exposure to coding before starting.

You'd almost need a skills camp before the bootcamp that would be less choosy and take the top 20-30% of those students into a further bootcamp... but at that point the economics start to break down (why it'd likely need to be pro-bono).

Anyway, that was a big tangent! I think what you're doing is interesting. Do you have a twitter account set up if we're interested in following along?

What these programs need most of all are cheap dormitories that offer room and board. (Close proximity to students can also help provide one another with a support network.)

I think this is an excellent idea. There definitely is a gap in the market for non-CS grads who want to get a more robust grounding than a ten-week bootcamp can offer.

I'm interested in how you select applicants but your website doesn't let me look at the application process. Your funding model means selecting the right students is crucial as you carry the risk. How do you select from the candidates? Are they meant to be already quite experienced? I looked through the curriculum and it seems very intense even for someone with a bit of coding experience. How do you make sure people keep up the pace?

Amazing! I'm pleased to see that there are startups out here trying to solve this type of problems. Taking the risk is ballsy and should be rewarded!

Questions!

- Do you plan to extend the syllabus to something more fundamental? Asking because you have some C++ and already go further than bootcamps, so I'm wondering if you intend to pursue this direction and get closer to a formal CS education.

- Do you plan to work on giving some sort of degrees later? Some countries require degrees for immigration, which is a door that bootcamps do not open. By offering degrees, you open the global market to your students, and in an increasingly connected world, it can make a huge difference. I basically owe my quality of life to the mobility I got thanks to my degree, and this is something I wish to everyone.

Massive Kudos to you guys! I hope you will eventually offer the same service to students outside of the US. The market is large.

This is similar to how all university tuition fees in the UK work, with slightly different numbers. A very sensible solution to the astronomical cost of education, provided people want to get jobs.

In the current UK scheme you pay 9% of the amount you earn over 21,000, or nothing while you earn less than that. Debt written off after something like 25 years if unpaid.

Brilliant, I've long thought that all universities should run under this model (although when applied to the humanities I can hear in my head the 3000 years of the land owning, non-laboring intelligentsia protesting about the noble virtues of an education uncorrupted by the banalities of productive yada yada...) But anyway back to CS.

1) Risk is pooled in the institution rather than distributed amongst the students, which is the textbook way to deal with uncorrelated risk.

2) The incentive of the university and the student are aligned as much as possible

3) By putting costs and benefits into a form with equal time horizons, disadvantaged students no longer need to rely on the generosity of governments or private lenders for upfront cash.

The only thing I'd always questioned was whether such a scheme as described above could pass legal muster, as it bears a resemblance to involuntary servitude, as well as requiring access to income statements. I've never heard of anyone but the govt placing liens on income. I'm hoping a workaround has been found, because from a strictly incentive based analogy, this model has the potential to do to modern education what patent law did to manufacturing

This is poorly thought out and edited, because I have to run, but I thought it worth posting. I've been thinking more about libraries lately. I really think it is time to reinvigorate and expand them. Pretty sure I'm preaching to the converted here about the power of information; I think what some folks miss is just how incredibly valuable libraries are. No, they aren't a panacea, but they are a cheap source of immense social good.

A lot of people see a building full of books and wonder why it can't be replaced by a bank of terminals and Google. I won't get in to the relative merits of dead trees vs. electrons, and largely don't care about it. What that line of thought misses is two-fold: the librarians and the community space.

Decent librarians are hugely underrated resources. Great ones can be incredible. Maybe natural language systems will become good enough in my lifetime to handle some of the vague requests librarians routinely manage to match to the right book, but the leaps of association to related topics, the knowledge of the edge cases of information classification to navigate them well, and the general mass of knowledge they accumulate is massively useful to have on hand. And so few people take advantage of it.

Meeting spaces in this context (both formal, sign-up-for-your-group and informal) serve an important role as well. It seems[1] like they're becoming rarer as government buildings use security as an excuse to close to the public, and in calling around to private groups with spaces that previously did that sort of thing have been much more reluctant to do so when I've tried to organize things over the last several years.

To personalize this a bit, I grew up in a poor family. One thing that was heavily emphasized to me was the value of learning - I think it was reaction to missed opportunities. Who knows what would have happened, but I do know that my college essays (written referencing library books, building on interests fostered in the math and the American Lit sections) would have been very different without them, and I kinda doubt I would have gotten a free ride to a top-10 school if I had been only drawing on what public school offered.

I'd love to see more experiments with libraries. I know some are playing with becoming more "maker-space"-ey, which is a decent thing to explore. I think finding a way to offer peer-classes in whatever - learn Javascript, fancy knitting techniques - would be an interesting thing to try as well. But I'm bad at seeing opportunities like this. I wonder what people with that super power could come up with.

The modern day equivalent of a public library (storing information history) is the internet archive.

I think donating to the internet archive would be a better donation which a lot more benefit to society than funding physical libraries.

Libraries solve one of the worlds most important problem - keeping societies important information history safe. Websites are not immune to this problem. They require maintenance. When a webpage goes down its gone forever. Without something like the internet archive, we would not have a modern day library equivalent for the web. We are losing a lot of important information. Physical libraries today are in comparison much less important than digital ones.

The problem libraries solved, mostly access to information, has largely been monopolize by the internet. Most, including the third world impoverished, have access to the internet. Therefore the necessity of a library has been largely diminished and inevitably libraries will disappear. Complaining about libraries when people have no sanitation and access to clean tap water sounds largely like a first world problem, as much as I dislike the term.

Libraries should evolve with the change of technology and move their function from curation and access to information to something that is able to benefit more people. Books occupy volume and removing them would make more room for desks and rooms where people with no access to quiet areas could use to be more productive.

I think this is a good idea. I would add YMCAs and similar places.

I think one of the best places for a mega-philanthropist to invest would be in the time and places that kids spend outside of public schools. Many of the biggest disadvantages in opportunities for kids are created when they fall behind before and after school and during summers, relative to kids who are better off socioeconomically. These disadvantages compound and are lasting. Safe places to engage in healthy recreation, productive endeavors, and getting something nutritious to eat that they wouldn't otherwise have access to would go a long way for underprivileged youth and have an impact for the rest of their lives.

As much as I hate books, I love public libraries. Our local library (Northside branch santa clara) gives a big conference room every saturday to a team of passionate locals trying to teach themselves programming. My friends and I go there every Saturday to help people who are stuck and give them guidance (what to learn next, how to prepare for interviews, what language is best suitable for what they are trying to do, etc).

Talk about diversity, the library is a place where you get to see people from all walks of life outside the silicon valley bubble (different race, age, handicap). It builds a learning community where people have the opportunity to help each other at a more human level.

Here's a better idea...and one that will ultimately benefit libraries as well: start buying out all the evil academic publishers, overhaul their technology, get rid of copyright assignment, and offer free access to anyone.

Then do the same with legal records, although that is more of a legal problem than a money problem.

I don't know how it is in the US, but for instance German libraries offer to loan ebooks: http://www.onleihe.net/

Donating ereaders and rights to ebooks to libraries seems more effective than printed books.

Big caveats here are Amazon's monopoly position, DRM and copyright and loans for ebooks vs. physical books.

Strengthening public libraries is an excellent idea, with lots of public benefits. Libraries are one of the most trusted public institutions in the US and provide a range of key social services including access to education, internet, health information. They also reach and support a demographic that is currently not well served through online-only programs.

I co-founded Peer 2 Peer University [1] a non profit that brings people together in learning circles to take online courses. When we switched from online-only to face to face meetings in public libraries we started teaching adults who had fallen out of the education system and who were not benefiting from online courses. And I can't say enough positive things about the librarians who we work with.

No offense to the author, but what a tremendously stupid idea.

With technology becoming cheaper and cheaper, right now, you can get a good enough computer to access all the world's information (the Internet) for $25. I can imagine that price being more like $5 in the next 10 years.

Since the goal of investing is planning for the future, it'd be an enormous waste to spend all of that money on the antiquated concept of a library. It will be about as useful as investing the money in VHS tapes.

Better education-related goals for billionaires: make more of the copyrighted information available for free public use. Help increase access to good quality internet and computers in poor communities.

I think public libraries would be a wonderful beneficiary of Jeff Bezos' fortune, but I would hope that in the (admittedly unlikely) event that it happens, the bulk of the donated funds are not thrown at shiny "library of the future" initiatives. Not after-school STEM programs, not summer Minecraft redstone programming camps, not 3D printer labs.

Just books, staff and facilities: the three things that libraries always need, won't become obsolete in a few years, and are equally available to all patrons in an area.

Yes, public libraries need to evolve to meet their community's needs as they change. But just as a new coat of paint or solar-powered lighting doesn't strengthen an aging bridge, focusing on the flair rather than the core of what makes a library a library would be foolhardy.

tzs 1 day ago 1 reply      
I'd like to see some billionaire put a lot of money into abortions. The political fight over abortion keeps messing up other things, and a billionaire could fix that.

For example, I don't think many on the right disagree that funding prenatal care is a good thing--but some major prenatal care providers, such as Planned Parenthood, also provide abortion services and so some politicians want to cut all their funding to make sure none of the Federal money goes to abortions. A whole bunch of women's health services get cut in order to make sure there is no chance the money ends up helping abortions.

So I'd like to see some billionaire, or some well-funded charity like the Gates Foundation, build several clinics that provide free abortions around the country in the states with the least restrictions on abortions, and fund a program that provides free travel to and from those clinics for women in the states with restrictive laws that have forced most such clinics to close.

Then organizations like Planned Parenthood can get completely out of the abortion business, taking away the major excuse that is used to cut their funding.

State legislators can stop spending a lot of time coming up with new ways to try to shut down abortion clinics in their states (because shutting down such clinics will no longer stop the abortions), and state attorney generals can stop wasting time defending those attempts in court, and maybe they will finally realize that the best way to reduce abortions is to make it so people don't need them in the first place. Maybe then states like Texas can drop their idiotic "abstinence only" approach to sex eduction (which has resulted in soaring teen pregnancy rates...) and switch to something actually effective.

Edit: any down voters care to name specific objections? That Planned Parenthood provides a lot of useful women's health services that are not related to abortion should not be controversial. That abortion is the main reason Congress wants to completely defund PP should also not be controversial. That "abstinence only" programs are a massive failure is pretty well documented. That many states keep passing abortion restrictions which then get challenged and often struck down as unconstitutional is not controversial.

I tried cgo, .so files, and the like, bit this was a lot more trouble and had issues on both Windows and alpine-flavored linuxes.

Is there some issue with this approach that I'm missing? Is the additional process overhead really enough that it's worth bending over backwards to avoid it?

For example, I suspect I should be saving g before the jump, the stack size is completely arbitrary, and shrinking the trampoline frame like that will probably confuse the hell out of debuggers.

So when you actually fix all those things you might be back where CGo was at the beginning.

This guy comes across as a classic "but i wanna be cool" hacker who discovers that when you bypass all the normal protections in a library and make some kind of direct custom call, things can be faster.

I wouldn't get your hopes up, biosythensis is a much messier and less defined process than chemical synthesis, meaning the route to market is much more rugged. There are some cool use cases that may arise - such as rust eating bacteria - but in general I'd expect an experienced synthetic chemist to be a more economy favorable route to most chemicals. Partial synthesis, where a chemist works with a partial product produced in yeast, might yield good results in some edge cases.

This includes automatic migration of the schema, constraints, indexes and obviously data. It leverages fast bulk loading tools like mysqlimport, and PostgreSQL's COPY FROM. It doesn't need any config. Just plug and play.

The tool uses SQLAlchemy to abstract column types, and handles various column type conversions between any flavor of SQL.

The one thing it needs are tests, and scalability support for tables bigger than a few GB!

One of the main things I ran into when migrating from MySQL to postgres was that the default text columns (TEXT, VARCHAR, etc) behave differently when searching. MySQL matches text case insensitive, while postgres matches it case sensitive. This resulted in searches for content suddenly not returning data. Luckily there's an official CITEXT extension for postgres [1], which matches text case insensitive and adds the correct indices for doing so efficiently.

I'm not against the idea of using postgres, but I have a sneaky suspicion, that you could have gotten that 30% speed benefit from MySQL, if you did some performance work on it. Or in other words, I don't feel that migrating from one relational database to another similar relational database was worth that much trouble.

The lesson to take away from this regardless of your political leanings is that whatever power you give the state to go after a group you may disagree with will always, eventually be used against you.

It makes no difference if the target groups are alleged terrorists, alt-right, alt-left or or any other group. When you expand the power of the state that diminishes the privacy rights of the citizen that law applies to you, your family and your friends also.

I've been off Caffeine for a good two years now and have no plans of going back.

Life runs too fast for me on caffeine, yes I can blow through work faster, but when I was on caffeine it would feel like days, weeks, months would go by in the blink of an eye.

I wasn't enjoying the moment.. and then I stopped drinking caffeine.

Life became more present for me, not slower in the bad sense, but that I was able to relish every moment more, more aware... more conscious of what was going on around me. My fuse also got really short when I was consuming caffeine, I'd get into a lot of fights and arguments, since I've stopped, it's really helped.

I still get all my work done and have time to spare, I'm working, going to school and have an infant at home. So life after caffeine is definitely possible.

What the author didn't mention, and I haven't seen mentioned in these comments, are the extremely beneficial health effects of coffee (not caffeine, decaf has shown the same benefits). Most significantly, studies have shown that coffee reduces overall mortality rates significantly, with the reduced chance of dying from any cause increasing with coffee consumption (up to a point).

>Compared with nonconsumers, participants in the highest quartile of coffee consumption had statistically significantly lower all-cause mortality (men: HR, 0.88 [95% CI, 0.82 to 0.95]; P for trend < 0.001; women: HR, 0.93 [CI, 0.87 to 0.98]; P for trend = 0.009). Inverse associations were also observed for digestive disease mortality for men (HR, 0.41 [CI, 0.32 to 0.54]; P for trend < 0.001) and women (HR, 0.60 [CI, 0.46 to 0.78]; P for trend < 0.001). Among women, there was a statistically significant inverse association of coffee drinking with circulatory disease mortality (HR, 0.78 [CI, 0.68 to 0.90]; P for trend < 0.001) and cerebrovascular disease mortality (HR, 0.70 [CI, 0.55 to 0.90]; P for trend = 0.002) and a positive association with ovarian cancer mortality (HR, 1.31 [CI, 1.07 to 1.61]; P for trend = 0.015). In the EPIC Biomarkers subcohort, higher coffee consumption was associated with lower serum alkaline phosphatase; alanine aminotransferase; aspartate aminotransferase; -glutamyltransferase; and, in women, C-reactive protein, lipoprotein(a), and glycated hemoglobin levels.

http://annals.org/aim/article/2643435/coffee-drinking-mortal...

In addition, according to other studies, coffee prevents and/or reverses liver damage due to alcohol consumption. One study suggested an extremely significant (44%) reduction in occurrences of cirrhosis among those who drink 2 cups of coffee a day.

When considering whether or not to give up your morning coffee, consider the good with the bad.

One of the more interesting comments in the article is in regards to the social stigma of only consuming water during meals - people who have quit alcohol for various reasons have faced the same stigma when going out with friends.

I've found that ordering something that has little to no calories or substance goes a long way to alleviate these fears (like tonic or sparkling water).

Because something like this still costs money, it helps convince the purchaser that they aren't appearing to be "cheap" by only ordering water. Topo Chico (a sparkling water similar to San Pellegrino) is a favorite among recovering alcoholics in my area.

I am a coffee drinker but I don't really get boost or anything. Nor do I feel tired or anything else that could be called withdrawal during the weekends, when I don't drink it.

For me, making a cup of coffee is just a... ritual of sorts. Weighting the beans, pouring over water, all these things. And I really enjoy the taste, trying different beans. I don't want to sound pretentious, it's just a hobby for me.

Maybe there are some alternatives to it (tea?) that have lower impact on health over time, but I haven't really explored it.

Things like this generally make me wary. Not so much because of them causing side effects that are harder to disentangle, but their adoption indicating that the author is fairly stabilized, which is a giant side effect in itself.

I drink coffee because I enjoy it, not to give me a "boost" in the morning. I limit myself to 1 large mug per day, with the (very) occasional afternoon cup. I don't notice any difference between my energy levels before / after my morning coffee, nor on days I skip it. I get a headache in the early afternoon when I skip it, though, so I'm definitely addicted.

I wonder if the author's energy level issues were due to his "ever-increasing consumption".

I occasionally quit caffeine as a way to recalibrate the tolerance that develops over time. But, within certain limits (my general consumption is 1-2 coffees a day, sometimes 3-4 if super tired or when exercising), there's very few negatives for most people, and quite a number of benefits. Nice explanatory video on the matter: https://www.youtube.com/watch?v=OTVE5iPMKLg

Quit coffee 6 months ago after 20 years on the daily (generally 2 very strong home made double or triple espressos).

It's not so much that eliminating caffeine is a life changing experience, but rather, you're unchained from the necessity to, above all else, get your caffeine fix. Some people can take it or leave it, go without for days at a stretch, which was not at all the case for me -- the only time I ever went without was when bed ridden or on a meditation retreat.

In terms of energy, the reserves are deeper, since the energy depleting caffeine rush is gone. Also, quit consuming refined sugar, which may be a bigger win than quitting caffeine -- I think it's closer to the natural state that humans experienced long before concentrated Xs came into being.

You have to want to quit. If you're younger you probably can withstand the racing heart, having to urinate frequently, insomnia, mood swings, and other negative side effects that inevitably affect the aging caffeine drinker.

I love coffee, "wake up and smell the coffee" has a true meaning to me. I usually drink one or two cups of black (no sugar) coffee every morning, and 2 espressos during the rest of the day.

I exercise on a daily basis, I eat well and I go to bed on time and I usually sleep between 7-8 hours.

I don't have the same side-effects most people talk here, thankfully, because the smell of a just made home-made coffee is one the best things ever :P

Quitting caffeine is hard, but I found a workaround: get the flu.

If you're like me, when you're sick in bed, the last thing you'll want is coffee. By the end of your flu, you'll also have gotten off caffeine and you'll have ascribed the withdrawal symptoms to the flu. Done! Now go buy some decaf :-)

I only drank coffee regularly for a few months in my life and the past five years I've removed all caffeine (that I'm aware of) from my diet except for special occasions where I need to stay up for safety reasons, usually driving long distances (extremely rare). It definitely helps as I have insomnia. The insomnia did not go away, but I have noticed a huge improvement. When I do have caffeine it wires me up the whole day into the night, even if I drink it in the morning. I have no problems with energy or anything like that and also sometimes do the intermittent fasting the author talks about. All in all, I agree that it's a huge improvement. I'm also not dependent which is a huge plus and it saves money. I think it's definitely worth trying, especially for people that are consuming many cups of coffee throughout the day. Of course, as the author points out, if you are going to try it, make sure you get enough sleep. Focusing on getting enough sleep, I find, is a much better energy boosting technique (for the next day) than caffeine or anything else for that matter.

I've also been off of caffeine for about two years, for a few reasons (anxiety reduction, desire to be free of chemical dependencies, and especially sleep improvement). It took me about three weeks of depression and lethargy, but was totally worth it. My sleep especially is much-improved, and I'd say that my anxiety levels are generally lower.

The main thing is that you need to get enough sleep at night.

If you're interested, I found some support on reddit, http://www.reddit.com/r/decaf.

I love coffee ... when I'm addicted to caffeine. I found when I get off of caffeine my love of coffee disappears.

I've been on/off caffeine numerous times. Mostly because I have a big backpack trip where obtaining caffeine is a pain. It takes exactly a week for me with days 3-6 being miserable. I feel I am not fully "there" almost as if I'm an observer in my own body.

There are two advantages I see in being off caffeine. First you are not dependent on a drug. Second, if you do need the drug for a rare occasion (maybe driving late into the night etc.) it is there for you. Being off caffeine then drinking a cup of coffee gives you a huge jolt.

I got back on caffeine recently to see if it would help me lose weight. It did not. Now I'm fat and addicted.

The good thing about going off caffeine is that it works well when you have some from time. For example, when I have a long drive ahead of me I get some Starbucks. I am so sensitive to caffeine now that it keeps me awake the whole drive (and a few hours more unfortunately).

One thing that was striking to me when quitting caffeine (after drinking coffee consistently for years every day) was how after a week or two the feeling you have when waking up is completely different. I had always assumed when you wake up it was normal to feel terrible until the morning coffee. Not so. Off caffeine, a proper nights sleep will have you up and active right away.

I "quit" caffeine while dealing with a mysterious and persistent nausea which ended up being mild food allergies.

Either way, before I knew what was going on, I got frustrated at my textbook healthiness yielding no answers, went off the low-carb deep and and cut out grains and sugars almost entirely from my diet.

Because my insulin/glucose levels have now moved from the penthouse to a basement apartment, I no longer have dramatic swings in energy throughout the day. My energy at 7AM is roughly the same energy I have by half after 4. I don't need caffeine or sugar to push me though a tired spell, and I haven't felt a caffeine/insulin crash in months.

Caffeine control is one thing but insulin is the body's top dog energy regulator. If you have energy issues, start by focusing on insulin, not caffeine.

I love coffee-- the smell, the ritual, the taste, but even 1 cup turns my anxiety from a normal 2/10 to a 7/10.

On top of that I don't even feel more focused or productive from caffeine. Actually I get easily overwhelmed and rather indecisive. My brain is not made for stimulants, as adderall makes me tired.

I'm going to try taking theanine with a cup tomorrow, if that doesn't improve things then I'm off caffeine for a long time.

I only started drinking coffee two years ago. First it was once or twice a week, then it became everyday.

About 6 months ago I started having slight muscle tremors, my doctor said it could be because of stress. I didn't tell him I started having too much coffee (nor he asked me).

But the tremors kind of increased slowly. I read on HN about some guy who had similar problem with caffeine shots. It then struck them that coffee could be the problem.

Now I rarely drink coffee and tremors are also gone.

I think the supplements and alternatives, which are mentioned in the article are a bit weird...I think those are sports-products, and not real alternatives to coffee.

I also want to reduce my caffeine/coffee intake, but I want to have the "same feeling" as when I drink coffee...

For this I drink the following:* My girlfriend showed me Caro Coffee (wheat-basis):http://amzn.to/2w8RhDu You make it like instant coffee with hot water (and milk/sugar)

* Yogi Tea (chocolate-taste)http://amzn.to/2wZCVSPUsually I drink this in winter.. But I'm not sure whether it is completly caffeine free.

* Eimalzin (malt-cocoa)http://amzn.to/2i3bTrsok thats just cocoa.. still I like it from time to time

* Zotter (various drinking chocolates)http://amzn.to/2w5W7SDhmm very tasty! but a bit "heavy", so I only drink them from time to time.

But I am always happy to find good tasting alternatives to coffee... Do you have any suggestions?

This article reminds me of what I have been wanting to do for a while, but have not succeeded yet in spite of having tried this a few times. The goal is to prevent large fluctuations in energy and mood. My plan is to:

- Quit caffeine

- Quit sugar (in all forms e.g. refined sugar, honey, fructose syrup etc.)

- Consume alcohol only occasionally

- Consume white flour only occasionally

- Meditate

> I dont think the ketones are necessary, but it helps me with running while fasted.

Our body generates ketones when carbohydrate intake is reduced enough, and it feels great. Perhaps the author's tinnitus may benefit from reduction in carb intake [1]. It is a common misconception to attribute certain benefits to presence of ketones while the actual benefit comes from the absence of sugar metabolism.

I have a lot of problems trying to quit caffeine. Ever since I was a young child, they gave me really powerful amphetamines to get me to focus. Then when I turned 18 it became much more difficult to obtain.

In the US, Ritalin/dexadrine/adderall are all class II controlled substances with similar restrictions to cocaine or fentynal, so in order to get it I would need to have a doctor's appointment every month, which wasn't only inconvenient but super expensive once I lost my mom's insurance.

So, dipshit that I am, I replaced it with megadoses of caffeine. At my peak, I was consuming 1g (yes, gram) of the stuff every day in the form of energy drinks. I am now down to 280-560mg per day on average. I have tried not drinking any, but the inability to focus and headaches mean that trying to cutback seriously puts my job at risk.

I really wish I could just get back on ritalin or something so that I can give my poor heart a rest, but I am afraid to walk into a doctors office after not going for years and asking for drugs.
