Well, it certainly is nice to see that Netflix's promise of securing higher-quality content is at least partially coming to fruition.

Also, it is nice to see a content creator finally start talking seriously about internet streaming versus traditional cable as a means of content delivery.

Blowing his horn and chasing Cape Horn dreams, Harry [Mitchell] sails out of Charleston on September 17 1994. 'For the rest of your life don't waste any time. Make the best of what you may before you turn into clay,' he told students before he left Sydney for the Southern Ocean.

(Harry Mitchell, age 70, was lost at sea in the Southern Ocean in the 1994 BOC solo around the world yacht race).

-- Paul Gelder, The Loneliest Race

I began to understand the struggle and the despair in the simply written ships' journals, in the monochrome prose that could suddenly bloom with feeling:

March 29, 1913: Terrible heavy NW gale. Lost mizzen upper topsail and main lower top gallant sail. Got two men hurt. All hands on deck all night.

30th. 6 AM: quick shift from NW to SW with hurricane force, with terrible heavy cross sea. Ship under two lower topsails and under water. Lost outer jib. Washed off the boom.

31st: wind SW. Very heavy gale.

April 1st: terrible heavy WNW gale, ship under two lower topsails and drifting to the eastward, and my heart is broken under these heavy gales all the time.

So reads the log of the Edward Sewell, 263 days out from Philadelphia to Honolulu, battering to westward in the grip of The Horn for 67 days.

-- David and Dan Hayes, My Old Man and The Sea

How Bad Boards Kill Companies: HP mondaynote.com

_delirium 1 hour ago 0 replies      
Boards are really not set up to do any sort of serious monitoring of a complex multinational corporation, especially if they're supposed to be doing it independently of the executives they immediately supervise (CEO/CTO/COO/etc.).

Nearly every major company's board is full of people who have more-than-full-time day jobs, plus sit on 3-5 other boards. There is really no way they can do a proper job in that situation; in practice, they devote one day a month to doing the bare minimum to fulfill the responsibilities of each board position they hold, if that.

For example, after a story about Cisco acting badly (http://news.ycombinator.com/item?id=2789540), I was motivated to look at who was on Cisco's board who might exercise some oversight. What I found didn't seem likely to be a group of people spending much time on the matter. One of the board members is the President of Stanford University, which I assume is a pretty busy job to begin with. Another is the now-former CEO of Yahoo mentioned in this piece. One more is the CEO of Mercer, the world's largest H.R. consulting firm. How much time do you think these people each take out of their day jobs to really understand how Cisco operates? I would wager very close to zero.

So this seems (to me) much more of a structural problem with how large companies are run, than an HP-specific problem. They may have gotten particularly unlucky roll of the dice, but this style of corporate governance isn't set up to favor good outcomes.

A friend of mine works in the publishing business. He equated the previous few CEOs of his (large) company to locusts.

They move through, cut cost by laying of people. That leads to great profit increases for a quarter or two, after which the lack of qualified employees shows its toll.

By the time that problems become apparent the CEO collected a huge bonus and moved on, leaving the mess for somebody else to cleanup.

The author is correct to blast the board, but the claim that Whitman "has zero background in tech" suggests that she comes to the HP job as an old-school industrialist. Starting in 1998, she spent 10 years growing eBay, which required an understanding of market dynamics and making some smart technology hires and acquisitions (including PayPal) along the way.

this is a perfect example of when checks and balances go wrong. While CEOs and boards may not see eye to eye on every decision they sometimes forget that they are not enemies. They should be working together toward common productive goals. Even though these are billion-dollar companies, they cannot afford to continue to destroy themselves from within, sooner or later profits will dwindle and they will be no more. Mistakes are bound to happen. But according to this article, HP doesn't seem to learn from theirs. They are thoroughly living the definition of insanity as if it were a religion!

I hate to bring politics into this, but regardless of whatever side you're on Congress and the president seem to be doing the same thing. Although they're supposed to watch each other. They forgotten that they're on the same side. It should be working together to get things done. Internal fighting and derision can kill governments, as well as companies.

For anyone who found this tale interesting, "Poorly Made in China" is a well-written and eye-opening account of similar antics.

http://www.amazon.com/Poorly-Made-China-Insiders-Production/...

Much like the kickstarter project mentions, this book covers repeatedly broken promises, misleading claims (like the laser etching that turned out to be CNC), continuous reassurances followed by convenient disappearances, completely mythical factory sites and machinery, supposedly mechanical processes that turn out to be skilled hand-labor, and the need for vigilant and cynical quality control. It makes a convincing argument that once you account for the cost of all these shenanigans, export manufacturing is nowhere near as good a deal as it seems.

I'm amused at the mindset of trying to do low-volume and hence (for the factory) low-profit manufacturing runs in China and complaining when it turns out to be more difficult than uploading a file and waiting for a box of Apple-quality products to arrive at your front door.

Simple economics - if it was easy, everyone could do it.

Pen Type-A is a stainless steel replacement for the Hi-Tec-C's cheap plastic housing. To us, the Hi-Tec-C cartridges deserve a more durable home.

This is kind of funny, I sort of did the same thing -- though my solution was much cheaper. I write a ton with ink and I had a hell of a time finding a pen that wrote smoothly, was gel, was rectractible (pen tops are a PITA), didn't smear, gave consistent lines, and was available at office stores for an affordable price. Well, the Pentel Energel pens met these requirements but the pen casing is flimsy and fat and very cheap feeling. So I just buy the refills and put them in a Sarasa SE pen casing. My only gripe is I would prefer a finer point. The Pentels only go to 0.7mm and I'd like at least 0.5mm, but this is good enough. Every gel pen I've used that size has problems (scratchy, suffers roller ball blowouts, etc.) so maybe good gel roller balls at that size present engineering problems.

Oh, and I also tried that Mont Blanc "hack" where you modify the refill cartridge so it fits in a cheapo Pilot G2 casing. I'm not willing to regularly pay $10-$15 for 2 ink refills, I just wanted to see what the fuss was all about. The writing was mediocre at best. Most noticeable was the problems I had with skipping and inconsistency. The value of Mont Blanc pens certainly does not come from the ink cartridges.

How much of this kind of thing is a by-product of marketers as well? I've seen more then a few events where the people who actually did the development were excluded to accommodate business partners and clients. It's not that marketing necessarily wants to exclude developers, but space and resources are limited, and socializing is an important tool in the marketer tool kit. Not that I condone this (having been on both sides of this equation), but it does speak to the shifting sands of prioritizing the goals of these kinds of events (is it a company celebration to thank employees, or a marketing event?)

Small non-exclusive company rails against big companies who shield their developers / have become exclusive, news at 7.

I'm all for companies that can keep developers and engineers up at the front, being deeply technical involved and interacting with their communities. But that's not going to be all companies, and Facebook in particular is one of those companies that is by their nature a closed system that builds itself not out in public (ala, say Mozilla), but through the proxy of press releases and new features dropped onto users' and 3rd partys' laps.

The other big factor I'd pitch would be consistency: how much technical content is there, and what amount is appropriate for a developer to be showing off? If the event is not inherently a technical event, a fifteen or thirty minute segment from a developer might seem really out of place. Developers are to be respected, but Facebook isn't a technical company, it's a networking company.

I have never had any desire to go to any conference, ever. What I tend to find is that talking gets very little done, and often not much is learned beyond a few truisms. If I want to talk to people I do it online, it is just more time-effective. At a conference, I don't necessarily know who a given person is, but online I have full access to their information (typically), and I only talk to the people I want to.

If I want to get into a good party (which is seldom), I go to whatever club is the current flavor of the month and shove a filthy wad of cash in the bouncer's hand. I could give two shits about an "exclusive" SV party, and I would hope most Facebook employees feel the same way.

The reality of the situation is that a party with 10, 100, 1000, 10000, and 100000 people feel completely different. With social dynamics being what they are it's difficult to invite everyone and still retain the atmosphere sought by the planner. I have no insight into the mindsets of the planners but I have a feeling the situation is probably the result of the realities of party planning rather than a desire to exclude certain individuals, or a class of individuals.

The situation with the B-list party could probably have been handled better with regard to musical talent and an obvious discrepancy between the talent invited.

I'm not so happy with the result. The parchment is too three-dimensional, which clashes with the font. I'd recommend regular (or calligraphy) paper (maybe printed with a non-white background, if your printer is good enough), and then "aging" it. Tea or coffee is usually a good method, although simple crumpling might suffice.

Also, either for a medieval source or a 1920s document, block lettering seems a bit off.

But this really shows what's possible if you have programmatic control over your typesetting. I really should do some (La)TeX again…

People really mean different things when they say "simple".

For someone it may be "the abstraction is so clean, small and self-contained that I don't have to look at the implementation", for others "the implementation is so clean, small and self-contained that I don't need any abstraction". The author of this post clearly subscribes to the latter philosophy.

I guess many flamewars on mailing lists ultimately boil down to this culture clash.

One of my favourite quotes from C.A.R. Hoare seems relevant:

"There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult. It demands the same skill, devotion, insight, and even inspiration as the discovery of the simple physical laws which underlie the complex phenomena of nature."

This is awesome -- a wise man.

However he is only able to do this because he writes in C. Python and Ruby are not slow, but they have terrible startup time, which causes a huge amount of overhead for CGI. They probably do 1,000,000x the work of a C program before getting to main(). I bet he statically links his binaries (or at least has few dependencies on share objects) because that has a pretty big cost too.

I wonder if he writing the CGIs in Lua would have the same efficiency. In Lua you would pretty much have to fork because it doesn't have threads and the interpreter is not thread-safe (no global interpreter lock). Or maybe v8 would work too.

Though it sounds simple, binary search is a minefield of edge cases and I've seen textbooks that do it wrong.

So when I read the GetMimeType function, I didn't think "how nice and simple"...I thought "Hmm, I bet that doesn't work."

To answer a few of the database questions that keep popping up in this thread:

1. Is it worth understanding relational algebra? Yes. Definitely. It's not that hard, there's more or less a one-to-one mapping of relational algebra to SQL. Relational algebra is both a useful mathematical tool and indispensable when trying to understand query optimization. Relational algebra is also necessary to be able to read pretty much any of the database literature, if that's one of your goals. (Just be thankful you don't have to learn Relational Calculus or Datalog.)

2. Is it worth learning XML features like XML DTDs, XPath, XML Schema, and XQuery? Yes, definitely. I don't like XML, but there are tons of places where you can use XPath. (The most interesting thing about XQuery is probably how similar it is to SQL, though.)

3. Is it worth learning about SQL triggers? Probably. Ultimately, the web development world is split between people for whom separation of concerns means doing more in the database, and those for whom separation of concerns means doing less in the database. If you think doing validation and transactions in the database is sensible, triggers are also a sensible thing to learn about. However, people like DHH disagree and want validation in your app server with a dumber backend.

4. Is this vocational training? Well, this is the first in a three class sequence at Stanford. This class is mostly about schema and query languages, so in some sense, it's the most useful to practitioners (or at least, non-DBA practitioners). The second class is about systems and implementation (on-disk layout, indexing structures, query optimization). In the third class, students either learn about distributed databases or actually build their own from scratch. However, schema and query languages have enough theory behind them, and enough generality, that I wouldn't consider it any more vocational training than a class on compilers.

If you're interested in this stuff, there is a "Camp DevOps" in Chicago next month.

http://campdevops.com/

Involves some of the same folks who put on the excellent Erlang Camp I attended last year, on the basis of that experience, I'd expect this to be a good value.

Speaking of deployment, anyone has a good suggestion for a simple deploying system in AWS? Ideally a generic EC2 instance is booted up with an apptype passed in, and based on the apptype it downloads the app code from S3 and starts up the app. The code is pushed to S3 by dev when it's ready. Is there such a system?

The part of the essay that stood out for me is this:

--
The panopticon was a building design dreamed up by the philosopher Jeremy Bentham, and in its most basic form, it's a prison scheme which allows observers (i.e., prison guards) to have a constant view of the inmates if they so desire, without the inmates knowing for sure if they are being watched. The effect, of course, is feeling that one is always being watched, resulting in altered (more “normal,” acceptable) behavior. Bentham's idea was, he said, applicable to poor houses, hospitals, schools, and mad houses " though he ultimately devoted his time to designing for prisons. The express purpose of the panopticon is behavior modification, what Bentham described as “a new mode of obtaining power of mind over mind, in a quantity hitherto without example.” No such prison was ever built to Bentham's specifications.
--

The author hit the nail on the head in drawing that comparison to Facebook.

I have long been unsure how the usage of such a version of Facebook would affect us. The answer might lie in the psychological effects of living in a Panopticon.

And at the bottom of the article is the call to "Like" it. And a button that has already told Facebook that I've read the article.

(Don't get me wrong, the web page has also told Google (via Plus and Google Analytics), Twitter, Chartbeat, and a bunch of ad platforms I was there. And a couple of CDN platforms, too, I guess. It's not just Facebook here.)

There's at least three points to be made here: There's a irritating design choice that doesn't let you easily specify a granular enough privacy setting (although this is weighed against the general pain of making choices). There's the fact that having a private or counterfeit or incomplete public online identity is getting ever harder these days. And there's the fact that large corporations are collecting ever more data on us, and this data is increasingly hard to evade.

I predict that Google+ won't win over Facebook in the classical sense, but force Facebook to reveal how exposed all of your content on Facebook actually is.

As Facebook embraces the "frictionless sharing" of Timeline and this auto-share (esp. for links clicked from other Facebook posts), they will eventually cross a line where users get dramatically less willing to share (as it's all on your behalf without your explicit command).

The way that Facebook termed this "Frictionless Sharing", along with the video game achievement image, was a marvelous piece of PR. Who doesn't like things to be easier, and who wouldn't object to their game achievements being automatically posted?

I predict it'll be a matter of weeks before people discover that they really do not want apps to transparently post all of their activities for the world (or even their 'friends') to see and there's a public outcry.

Tangential to the main point:

The OP just learned a valuable lesson in what computers actually do. The single char oops is usually programmers' first insight into what it really means when we say "computers do exactly what they are told nothing more or less". This is one of those things we all have had frustrate us to no end. Similar mistakes abound, and are one of the those things that cause a lot of people to give up on the programming thing all together. Here's a real kicker about it: they don't stop with experience, we just get better at noticing them faster.

For example about 2 years ago -- 5 years into a programming career and 12 years into programming in general, I had this code give me trouble:

   // C Code:
if (test_fails)
do_crashy_thing();

So I decided to throw a quick printf in there (the situation was such that learning the debugging tools available to me would take a couple weeks, so printf was my quick solution here). I should note that I hade been working heavily in python for the preceding 3 months. My code looked like this now:

   // C Code:
if (test_fails)
log("info about test");
do_crashy_thing();

Which caused my code to crash every time instead of sometimes. C coders will know that multi-statement conditionals need to be wrapped in { } but single statement ones don't. Further python if statements are indent scoped. The recent python work sort of made me blind to the problem in the code. After 3 days of WTFing, talking to the rubber duck, and so on, I called over a colleague and he pointed out the mistake in something like 40 seconds. A younger me would have been embarrased, but this just happens in programming.

My point is: these things happen, and I'm glad to see a blog post about this, without the demoralization that normally comes with it. I think it should be more openly discussed in tutorials and other newb oriented posts.

A few tips for anyone who is experiencing this sort of thing and not sure what to do:

Get a rubber duck (or whatever) and start employing the rubber-duck debugging technique: http://en.wikipedia.org/wiki/Rubber_duck_debugging it really helps!

Be willing to include colleagues early and often. Experienced programmers understand and won't think less of you. Doubly so if you are new. (The will tease you a bit about it, but in that shared experienced bonding way, not in the "mock the outsider" way).

Realize that as you are chasing the bug by getting down and dirty with other bits of the program, you aren't wasting time, you are most likely fixing other bugs that would have otherwise just manifested later anyway.

He's right, the "walking away" trick does work wonders some time. It gets you to relax, take a step back, and see the big picture.

The other aspect to this is reliance on Google. This is part stood out to me...

  I start to panic a little bit...I turn to google hoping
for a quick fix and copy/paste one of my error messages
into the search box.

Unless Ruby/Rails error messages these days are completely anemic (I haven't worked with Rails in a while), then the line number and error message should provide enough clues to debug a misspelling without having to go to Google.

Trust your analytic abilities -- it will keep you from that "panic" state.

Instead of seeing an error and panicking, be like Stanley Moss in Wag the Dog -- "This is nothing" :) Eventually you'll get to a point like Paul Graham where debugging relaxes you:

  I like debugging: it's the one time that hacking is as
straightforward as people think it is. You have a totally
constrained problem, and all you have to do is solve it.
Your program is supposed to do x. Instead it does y. Where
does it go wrong? You know you're going to win in the end.
It's as relaxing as painting a wall.

Um, very true, but this would also be a sign that they need to read their stack traces / test outputs, and probably try a debugger.

Seriously. Debugger. For tests, it's as simple as `gem install rdebug` and put `debugger` in the failing test(s). When it stops on that line, type `eval instance_variables`, and viola - your array contains "@microposts" and not "@micropost". Running it against a full Rails application, especially with, say, Passenger, is a bit trickier, but it's still worth the initial effort.

When I first started programming, I wasn't able to do this. Walking away meant I kept thinking about it. Trying to go to bed was impossible. I -needed- to solve the problem before I could sleep.

Now, if I get frustrated, I'm much more likely to walk away and do other things and come back with a fresh mind later. It has almost always been helpful.

I think the key here is the low quality work at the end of the day. I often knock off when I detect that I'm running at a very low productivity rate. Invariably the next day the overwhelming and seemingly massive task from the night before takes just a few minutes for the well rested brain.

There's also something about the "self control as a finite resource" that comes in to play here.

I'd say this wasn't counterintuitive nor particularly abnormal.

Sometimes you can, for whatever reason, get so close to something - a project, a situation, a problem, a case, etc. - that you get tunnel vision and fail to appreciate the bigger picture. That's just a product of focus, determination, and ambition, I think.

Once you step out of that tunnel and focus on something else, you can release the frustration you had before and return to the problem with a clear mind and even a totally fresh outlook.

The problem doesn't matter as much as your own wellbeing, so there's no point in stressing yourself out over one when there are million other things you could be doing. Such a laid back approach may allow you to be more productive, hence in that case it would be intuitive.

One comment that I saw on the original thread was talking to people. I wanted to highlight this because it has helped me more times than anything else. Even explaining step by step what my program should do to my girlfriend, who has very little computer expertise in general and usually gives me a blank stare, can help a lot.

I remember finding an image on reddit a while back of a programmer laboring over his code for hours only to find a greater than which was supposed to be a less than sign, my thought was 'a mistake we will all learn again and again'.

While solving problems on your own is a great way to learn things, another solution to this is to just talk to someone. They don't have to be an expert in the field, they just need to be there for you to confirm your base assumptions are sound. In fact, often the act of explaining the problem to them will force you to think through your problem differently, leading to the solution. Like Kent Beck said, "Once a problem is described in sufficient detail, its solution is obvious."

I, like the rest of the commenter's here, do certainly agree that a break can be all you need. However, I think the OP is missing a valuable lesson, which is that not only should they focus on getting the code to work they need to understand what was wrong and importantly - how to spot the symptoms that it was wrong. In this case, it was a misnamed variable. It's great that that's been fixed, but it's very easy to go hurtling on into the next problem. A few minutes of reading the error message again (and perhaps trying to cause it somewhere else in purpose) goes along way in building up a much more reactive way of working.

Quake is also responsible for changing my life: after years of muddling around in BASIC and LOGO I started writing mods in QuakeC, which required me to write code, design a website, design and build models, and test and test and continually tweak and iterate on the experience. For the first time I was writing large code and doing serious graphics work, and I loved it deeply.

It lead me towards building websites and writing about games, and out of the Quake community I met people who ran Unreal websites - they gave me a copy of their CMS, and I ended up learning PHP/MySQL from it and building and designing bigger and better websites.

I dropped out of my Mechatronics/CS degree to pursue programming for a living - which lead to my first exposure to the then-revolting idea that programming and design were different disciplines. I spent years bouncing back and forth between the two, never quite fitting in, but learning a ridiculous amount along the way.

Now I'm at Google, technically employed as a software engineer but leading the design of a large product. I probably would have ended up somewhere in the software industry anyway, but I believe that I'm in this exact position, the best job I could possibly imagine, because of a chain of coincidences that were kicked off by Quake and its modding tools.

The quake community and game changed my life. Of course, when I started, it was mplayer. I had just traded my Playstation 1 for a 486DX, a huge mistake in everyone's eyes. I used my rich friend's grandmother's AOL login to get online. (This continued for 3-4 years, my mother still wonders what the "weird noise" was on the phone lines past midnight).

The broken physics and quirks of Team Fortress in QuakeWorld is what really caught my eye. I was hooked like a fiend. I was recruited by many guilds and known for my 9600BP lagging , teleporting and fragging! Not to mention my 1MB cirrus logic integrated video card, it chugged along at ~12FPS in 320x200(?).

I got interested in manipulating Quake. Living in MS, there were no mentors for learning to program or script. I went in blind and came out with a few mods.

Years later, I ported team fortress with quakeworld physics into Enemy Territory, (Feb/Mar 2004?), but never found anyone interested in doing the sound or graphics.

Obviously, my original endeavor into quakeC led to a whole new world of coding and languages!

At this point, I had a few life changes. I made a handful of lifetime friends from IRC and my old clans.

Now, looking back, it was Quake and my natural ability to tinker that led to my pursuit of a degree in computer science/bioinformatics. I am currently in my junior year.

I emailed John Carmack a few times asking for legal advice regarding using shareware Quake 1 models in a development version of my port of QuakeWorld to ET. He gave me good advice and has been a great influence.

Oh, and trying to figure out how to make VIS run faster on a BSP map was the end of me. VIS took forever, and I mean forever, to run on my 100mhz computer.

I wouldn't say it changed my life, but the first pretty serious piece of software I ever wrote was a game loader for Doom/Doom II/Heretic/Hexen. You could select which game you wanted to play, and which WADs you wanted and if the WADs were originally created for a different game it would run them through a conversion script for the game you wanted.

Later on I added support for DeHackEd so you could modify the exe to change things like weapon speed power. Pretty sure I had support for setting up multiplayer games as well.

It was all written in Turbo Pascal and had a really nice GUI where I programmed all the primitives (radio boxes/check boxes/scroll boxes/buttons/etc) myself from scratch.

I really really wish I still had source code to the thing, but I lost it years ago. I was really proud of it.

Grappling hooks, bots, friendly attack dogs, Quake Rally which converted it into a racing game, Air Quake which added pilotable helicopters and tanks... I didn't get into coding until UnrealScript, but Quake 1 definitely got me into the internet.

I started out with tools like Deluxe Paint and Animation and QBASIC. I learned 3D modeling long before I touched a level editor, using tools like POVRAY and some crappy Windows 3.1 3D rendering/modeling package. I think the first level editor I used was Ken Silverman's for Duke Nukem 3D. But if I had to point out a game that really changed my life, it was Ultima 7 - it inspired me to learn art, programming, design, etc. It was so far ahead of its time and even was more interactive than many games are today. It was the closest thing to a "sandbox" game at that point in time, I think.

I like to receive emails and texts at 11pm), which it reserves the right to sell. And for a website that doesn't have an obvious charging mechanism, what else can I assume except that their revenue stream will be selling my data?

This article is so typically dork-disconnected-from-world that it's a bit sad, really.

Any site that uses SOAP violates HTTP (use POST also for GET-style requests). Any site that has delete links (as opposed to buttons) violate HTTP (barring onclick ajax action, that is). The big mega bucketload of sites violating HTTP this way (GET having severe side effects) is the very reason offline browsing and prefetching never took off much. Every site that uses comet very much violates HTTP.

This is no "message to the future to Mark Zuckerberg". It's just using the available tools for the job to their limits.

Note, I'm just as much against the whole frictionless sharing thing as most people here. But the moment we allow geek nonsense like this to overtake the real arguments is the moment the world will stop taking it seriously. This is what happened to the net neutrality debate ("net neutrality"? who made up that term? how will i ever make my mom care about that?), let's not let it happen here.

Sorry, but this really feels like hyperbole to me. For two reasons:

1) Before any action is shared back from the site to Facebook, the user has agreed to authorize that site (application) and add it to their timeline. Part of that dialog shows what's going to happen (https://developers.facebook.com/docs/beta/authentication/).

2) There are plenty of other examples around the web where submitting a HTTP GET request results in an action. For example, clicking an up arrow on Hacker News submits a GET request which increases the karma score on another author. What becomes more important is how you protect against XSRF and crawlers not accidentally changing state within your app.

michael_dorfman 9 hours ago 1 reply      
The important distinction here is that the user did not request the side-effects, so therefore cannot be held accountable for them.

But the user did request the side-effects, when he installed the app, and approved the TOS which specifically said that there would be "frictionless sharing".

Personally, I'm not interested in oversharing, so I'll avoid these apps; but, hypothetically speaking, if I were the kind of person who wanted his friends to know what he was listening to on Spotify, it would be a major pain in the ass to have to manually post a separate update to share the title of each song every three minutes. For this use case, it makes much more sense to install an app that will auto-post the songs, giving prior approval up front, and skipping the friction of asking again with each song.

To suggest that this violates HTTP seems more than a bit hyperbolic.

dasil003 6 hours ago 0 replies      
I'm always happy for another article denouncing frictionless sharing, but I think it's a weak argument.

On one side you have the fact that this is not technically an HTTP violation, because it is not the GET request itself that is triggering anything. It's javascript running in a loaded page after the GET request is completed.

On the other side you have the fact that Facebook does not care about what some tiny group thinks. Even if it were a true technical violation, Facebook doesn't give half a fuck about what web purists think; they will only change their behavior when there is a massive uprising among a significant portion of their user base.

Attempting to make it a technical issue detracts from the social contract argument which is the real issue, and also one that can be explained to anyone: you read a page and Facebook posts it to your newsfeed. Even your mom understands that explanation, and it probably freaks her out. We need more people trumpeting this from the tree tops (outside of geek blogs too) because I think Facebook is ruining it for the rest of us who would like to use some of these techniques to provide actually useful services instead of shitting all over user's privacy to make a quick buck before the government decides to get involve and lock everything down.

zhoutong 9 hours ago 2 replies      
If it's only a protocol violation, I guess Facebook can use JavaScript to generate a POST request instead. And in fact, they should be doing so.

The permissions and responsibilities of a user should not be associated with the type of request. Although it's true that users should not be responsible for a GET request, but the retrieval is based on the web page itself. The Facebook SDK will generate other requests automatically because the permissions have already granted. The GET request is only the trigger. (Imagine you have already agreed to post everything on ReadWriteWeb to Facebook through their reader app by a POST request, all these are hidden until you read an article. The side effects were already generated.) So I think this is not a protocol violation.

Let's stop for a moment and consider how the web actually works. Your browser sends an HTTP GET request for a page. The response for this page contains HTML and JavaScript. The browser then executes the JavaScript, often making other requests (GET and/or POST) in order to do its work. In the case of most Facebook operations (I haven't looked at this one specifically), JavaScript executed by your browser makes these requests on your behalf to communicate with and display information from Facebook. Google Analytics works this way too, making additional requests to a different server from the page you directly requested.

Unless the website in question has a back channel directly to Facebook, through which it communicates information about the GET requests you've made, the initial GET request has nothing to do with the data sent to Facebook. Furthermore, because of browser security limitations, this back-channel approach is not always even possible, since the original site does not typically know your Facebook ID (this may not be true for some sites with which Facebook has special partnerships, e.g. Yelp and TripAdvisor). Only requests made to facebook.com would have the cookie information that identifies you.

In summary, the HTTP GET request you make to fetch a web page has nothing to do with the information sent to Facebook, and HTTP's recommendations about GET requests have nothing at all to do with these other requests.

Also, people have been senselessly abusing HTTP for years.

What a bunch of nonsense. 'GET' must be idempotent, that is all.

Facebook is big enough that all sorts of sophists are going to come out of the woodwork and make plausible-ish arguments against everything they do. The motivation to do this isn't that it is good or something, it's because if you can say something bad about facebook, your comment can become news. That doesn't mean they shouldn't be scrutinized, but it also doesn't mean that we should pay attention to stupid articles like this. Or does the 'andothernoise' author think that collecting analytics 'violates http'?

A big reason for this is that it breaks a fundamental contract of web interaction, in place since the beginnings of the web, that users have come to rely upon.

How have users come to rely on GET? Ok, it makes a useful "Would you like to resubmit this action?" popup when you click the back button. And it can be useful to prevent XSF attacks. But neither of these is really relevant to frictionless sharing. Really the only thing I can think of that may be problematic is the possibility that spammers might be able to use it for spam. But then again, I'm pretty sure I violate HTTP on a daily basis. Maybe I'm one of the bad guys.

In regards to violating HTTP, Frictionless Sharing isn't in any way different from every other non-RESTful service/site on the internet. Facebook could have just as easily implemented the same service RESTfully (not violating HTTP), and it wouldn't be any different.

GET requests have the stateless/idempotence constraint so that they're cacheable, and timing between requests, out-of-order requests, and multiple requests don't become an issue. The 'accountability' referred to in the post is about users of the API - they shouldn't be expected to be aware of server state/side effects, in the same way that users of a function call shouldn't be expected to be aware of its implementation/side effects. It's an engineering constraint - it's not about honorably keeping end-users unaccountable for reading your webpage.

There is no violation of RFC 2616. Two points:

1. The implementors RFC 2616 is concerned with are: (i) of the server involved in a connection, (ii) of the client to that connection, and (iii) of the network that joins the two. Facebook's involvement as a server ended before these connections became live, and so is not one of (i)-(iii).

2. The notion of safety here is in the sense that inserting arbitrary get requests into a sequence of transactions between client and server will not change the semantics of those transactions. It does not have anything to do with what code the user might have asked the browser to run on receipt of the results of a GET request.

See, e.g., Mozilla's documentation of HTTP: A safe method is a method that doesn't have any side-effects on the server, from https://developer.mozilla.org/en/HTTP#Safe_methods

A quick look over the tutorial, it seems that a HTTP POST is actually made to declare that an "action" (e.g. read, watched, listened) took place.

You would also need to be authenticated into Facebook and the app would have to be authorized to post the action as others have pointed out.

Does a URL shortener violate HTTP when it offers analytics on GET links to the public?

I think the OP should understand that HTTP is a leaky abstraction.

GET requests always have some side effect, either on the server end or the client end.

Server A and Server B.

A GETs B's data and and offers a mutated version of it, which B GETs, and further mutates. Side effects with no POSTS! This is natural too, in a distributed environment, since each agent should be responsible for mutating its own state, rather than have B POST something to A. You can't abstract this dynamics into HTTP, but you can use HTTP to handle the underlying communication mechanics, like caching and authorization.

Using this argument, essentially every website that uses Google Analytics violates HTTP. The GA javascript triggers a GET request every time you visit a page that it's installed on, and the GET request has the side effect of recording your visit.

Like it's so hard to differentiate between a GET that user was not responsible for and which didn't complete, to the one the user was responsible for. As long as facebook makes it easy for an user to turn off an app that's spammy or the one that knowingly posts "I read an objectionable content", I think we are fine. Agreed, apps have more power but as long as users and Facebook have more, they will behave and internet will become a better place.

"This extension can access: Your data on all websites"

This part made me chuckle a bit. We are so afraid of Google and Facebook tracking our searches/web pages, yet we freely install plugins from 3rd party developers that can easily gather everything that Google and Facebook can get, and more. In theory, I could make a Facebook Disconnect 2, which secretly sends data back home about what pages have been visited, and nobody except the most vigilant (enough to read the source of the plugin) would know.

Why do we not trust large corporations who have billions of dollars at stake, but trust independent developers who have little skin in the game? Is it because we are those developers, so there's some form of camaraderie?

Absence of malicious history/intent doesn't render them incapable of being (directly or indirectly) dangerous. One could easily pose a rational argument for users to take prophylactic measures (e.g., Facebook Disconnect, Ghostery, and the other browser plug-ins) based solely on the increasing number of data breaches.[1][2]

However, this is a relatively weak argument, as it requires making an underlying assumption that the leaked data is dangerous. We have no evidence to support the assertion that leaked information of the kind shared on Facebook would pose any danger to the affected users. This is fundamentally different from the dangers of data breaches concerning health and financial records; these records contain information necessary to steal identities and engage in other nefarious operations. Facebook doesn't collect social security numbers or other extremely sensitive personally identifiable information.

Facebook does, however, collect evidence of our predispositions and predilections. Arguably, this information is far more dangerous than mere personally identifiable information, because rather than identifying us outright, it gets to the heart of what makes each of us unique. We are incapable of imagining the complete set of scenarios where this information could be used nefariously, and as such, its dangers fall within the scope of ``unknown unknowns''

Compare this situation to the case of a breach of financial data: the uses of this data are well-enumerated, and one could argue that the cost of the next health information data breach is a known unknown. Based on historical evidence, we know that another breach will occur, and we know how criminals use the leaked information. With data on Facebook, however, we don't know whether this information could be used maliciously. Moreover, if it could be used maliciously, we don't know how it might be used. Therefore, it deserves as much privacy (if not more) as one's financial and health records.

The committee was unaware that Google mixes two distinct services: key word search and question answering.

Key word search approximates your question and returns approximate answer. The amount of interpolation of approximations forces to display a long list of links. Here, the job can be done by simple ranking algorithm.

On the other hand, if we want to answer a concrete question we need to provide a concrete information. Watson would not win Jeopardy if "he" provided just a ranking. Here, the job is done by understanding the question. After that we just need a look up table. Google is not secret about their data model. If your web site is fully annotated with OWL and RDF, surly Google can use it for question answering look up resource.

To solve your customers' problems well, you have to understand their problems from their point of view. This is why technical people often need a business co-founder: one who understands the domain well.

I had a brief stint as a teacher (three years in a private school) so while my experience is not vast, I do have a sense for the teacher's point of view.

Teachers often do resent spending their own money on their classrooms, but it's not out of a sense of entitlement. Often the budget is tight, so teachers have to buy pencils, classroom posters, etc. out of their own small paycheck. Also, simple things like how many copies you can make are limited.

So imagine a software shop where each developer:

(1) had their bandwidth per month capped

(2) if they wanted an extra monitor, productivity software, or anything beyond the standard developer setup they'd likely have to pay for it themselves

(3) has their salary cut in half (or by two thirds)

So it's not a case of entitlement at all; it's a case of scarce money.

About teachers not wanting technology solutions: as a teacher I had very little time during the day. There were some days where I very literally did not have five minutes to spare and had trouble finding time to go to the bathroom (other days were more sane). My personality is one that craves change, but as a teacher I found that I was juggling so much work that I did not necessarily welcome changes to existing procedures. So I think there may be some truth to this in that teachers may not have the time resources to adapt to a lot of new technology. That said, target the teachers in the summer. They've got time to make changes then.

My fear is that just as interest in ed-tech is waxing, the field will be flooded by these want-a-be founders who fail miserably and then blame their failures on parent, teachers and children. Education is a complex and difficult market that will requires a founder to have deep knowledge of its inner workings.

practicality beats purity, even though the Python
frameworks are moving away from the "MVC" term it always
felt like "MVC" to me, in that there are three distinct
components - data objects (model), some kind of "load the
model in response to a URL and display a template"
(controller, what better name is there, I think "view" is
a crappy name for that since it doesn't define
presentation), then the "template", seems like a view to
me - it's the thing you're viewing!

That the model isn't notifying the view through an event
system is splitting hairs. The GOF book is much maligned
I think because people insist on taking each pattern
completely literally down to the last detail. GOF's
pattern (GOF didn't create it but they discuss it on page 4, I thought I was crazy until I just checked just now) is specifically "MVC, and because we only know
about C++^H^H^H Smalltalk graphical libraries and not very much about
stateless HTTP systems yet in 1993, the model notifies
the view of changes too, how else would it work ?" IMHO.
It's an implementation detail, it's not the essence of
the pattern.

So if a JS framework is now doing MVC that includes the
concept of "model notifies the view", sure call it
"classical MVC" or "model-notify-view-controller" (MNVC).
Shrugs.

I don't see the point in making these subtle pattern distinctions. The model notifying the view is not significant enough of an architectural criteria to merit its own term. I submit that there are dozens of such architectural variances between MVC frameworks and that defining high-level terms to codify those differences isn't helpful. I'll even take it a step further and suggest that a focus on taxonomy diminishes ones ability to think fluidly about the low-level architecture and how to improve it to solve different problems.

This is quite different from (for example) the debates about the definition of REST. In that case there is a seminal paper and all kinds of subtle points leading to material benefits in web apps. What does Model2 have to teach us?

extension 10 hours ago 1 reply      
Here is my personal understanding of the principles of MVC, without regard to any specific platform or implementation:

The model is an API to the domain of the application that is not coupled to anything else. It is suitable for use with a user interface, automation, or as a component of a larger model. If the application domain is about storing data, then the model will provide access to that data and enforce its validity. But the domain could also be something that is not stateful per se, like interfacing with hardware.

A view is an independent component of a user interface for the model, and is tightly coupled to it. It allows humans to interact with some part of the model in some way.

The controller organizes views into a complete end-user application by instantiating them and connecting them to models. It should be minimally coupled to the details of views and models, and is optionally composable.

He is correct, but I doubt there is much confusion. The term MVC is used mainly to illustrate the separation of concerns, which is, IMO, the number one task for any framework.

Also, as far as I recall, the MVC pattern does not require communication between the models and the views, although it certainly allows it.

Looking at it from another perspective, MVC is a huge buzzword nowadays. It's simply not worth it to be conceptually correct for such a little gain.

The last time we tried to use MVC in GWT app, it didn't work out quite well. We decided to use MVP + EventBus instead.

These days the MS camp came up with MVVM (a variation of MVP or more closely related to Presentation Model, which I think MVVM is borderline architecture astronaut, but meh, I might be biased).

Something about this gives me the willies... It feels like a language designed on indie game forums for non-programmers who can about wrap their heads around the basics of ActionScript. The value it brings doesn't really make sense for a non-trivial project-- compiling for, say, Flash and <canvas> sounds nice, but in what circumstance would I really want the same code to target PHP, AS3, and C++?

Even the name seems to be saying "Using this will make your game cooler!"

On the other hand, when I say that out loud, I probably sound like quite the elitist... it's not doing any harm to me, and getting more people into coding has gotta be a net good. Maybe I'm just not looking at it right as a programmer rather than someone less technical who just wants to get their game out to as many people as possible. Can anyone set me straight on this?

Whoever is downvoting me is exactly who I mean.

Apparently there are technologies that can compile this to C++, javascript + CSS, Flash, webOS, and Android.

I haven't used this, but javascript + types (with type inference) is very appealing.
