Companies like this have been around for years, and whenever I read about them I'm surprised that people would risk going to prison (or worse) just to get a discounted air fare. I wouldn't even carry a package for a friend unless I could see exactly what was inside, let alone carry a suitcase full of unknown stuff for a total stranger.

Also, an inevitable question when going through security checkpoints in some countries is "did you pack your own luggage". I assume that if you answer "no", you'd be subjected to a very thorough search for bombs or contraband.

Calling a company "Airmule" seems to be a particularly bad choice, since the term "mule" is commonly used to denote a person who carries smuggled drugs (sometimes concealed inside their body).

I cringe when I read such Trumpian tweets from a founder. The journalist reached out a few times and the response was unclear. So he writes his piece with a pretty clear warning to future customers. Get your PR and compliance straight if you want to avoid such pieces, don't complain afterwards while calling names.

Caveat emptor. Just those responses are a red flag, if the subject is legal risk surrounding smuggling to PRC. They don't want you to know.

If you can't answer a yes no question without wishy-washy flim-flam pr doublespeak then you don't get to complain that an article doesn't have facts.

and while i'm ranting. what is with founders presenting them selves as "bro's at the bar"?If the founders had bios that looked like they were from upper management at ibm i might be more likely to use their service.

I don't know anything about airmule's operation or China's customs/security, but the on-board courier industry is a legitimate one that has regulations and procedures that it's not clear the author of this article is aware of.

> "We have found contraband in [courier] shipments," says U.S. Customs official Bob Fischler, "but percentage-wise it is infinitisemal. And in any seizure we made, it was obvious that the on-board courier had nothing to do with it." In fact, at New York' JFK and at London's Heathrow airport, because of the sheer volume of courier shipments, all courier pouches go to a central location for clearance. The courier is typically dismissed before customs physically inspects the shipments.

I find responses like those given from the co-founder here infuriating for some reason - far more so than I realistically should. I've always valued transparency when it comes to business, so when I see people dancing around straight answers and then lashing out when people take issue with said responses it just seems so remarkably childish.

The founder is lame and as /u/wjnc mentioned he has a trump-like behavior. The question is very simple: If there is drugs in the shipment, does the traveller get a FREE pass?

The article is lengthy and kind of make this question vague. In my understanding it is a single question: Who bares the responsibility?

Well, it is you the poor traveller. There is no way in hell you can accept such a deal even if you are flying for Free. In fact, if you are, ask yourself the question: Do free meals really exist?

This makes me super curious about the pre flight baggage controls. How do they handle someone who picks up the extra bag, but winds up not taking the flight?

With baby formula, i'd just return the bag and apologize, eating the $99. Heroin on the other hand, i could probably move at a steep discount. $1k or so, not worth the risk. $10 or $20k? hmm. The bag needs to be worth at least $1000 in the target country, just to break even.

it seems like pretending to be a stoner, and setting up enough to buy a plane ticket could get you a lot of money for $99. Fake id and a prepaid credit card aren't that hard to come by. It's not like the ID needs to pass TSA inspection, as you're not taking the flight.

Seems like a very risky business. If your customers are willing to be pasties, it'll be ok. but just a couple of sharks completely change the risk profile. Doing stuff that precludes government enforcement of contracts is just crazy crazy risky.

I can just see it at the airport. "Did you pack your bags yourself?". I guess at 40 I'm not the target audience for this, but I'd be worried a younger person trying to save money might end up paying a high price.The name 'airmule' doesn't do it any favours either.

It's significant that the business is about shipments from the US to China. That seems to be hard. Getting stuff shipped from China to the US seems to be ridiculously easy and fast. You can order stuff off Alibaba and get fast delivery via China Packet, which is a postal service with really good rates for China to the US. Delivery in the US is via the USPS.The other direction is much more expensive and slower.

The US needs to renegotiate postal rates with China. China is still getting the "developing country" discount from the USPS.

Looks quite shady, especially given we're talking about China. Anything being wrong with the package - not even drugs - that'd be insanely bad - but I'm sure there are many other things which require special papers to get into China, or are prohibited, and if something is wrong, it's the courier's ass on the line. I don't see how it could be worth the risk of being imprisoned in China. I mean it's one thing to be in a "gray area" as an American in the US, with all legal protections and ACLU and so on, and another thing doing the same in China...

And I wonder what TSA thinks about people transporting things that they have little idea about in their luggage?

On their website they state "Airmule then manually inspects and verifies each item prior to packaging for a traveler."but I doubt this company that started last year has more experience finding contraband than law enforcement doing it their whole lives who have seen everything. Pretty asymmetric risk profile, save a couple hundred bucks for potentially your life.

I frequently fly international with zero checked bags and about 5lbs of carry on.

I would love to be able to do so for $99 if someone wants to on-sell my checked allowance.

After reading the article I see the pitfalls I had never thought of, and would obviously want some extremely, extremely clear legalities to make it very clear the bags are not mine, and I'm not bringing them into any country.

No, I did not pack them and, no, I am not bringing them into your country.

When I was studying in Taiwan in the early 80s, the island's high tariffs motivated travelers to carry suitcases full of stuff--Walkmans, cameras, Italian shoes, etc. Contact a guy in Hong Kong, he gives you a bag, a guy in Taipei picks it up and gives you NT5000, enough to pay for your ticket.

I never got up the courage to try it myself, but friends did. My girlfriend did it once.

Looking back, I realize how exceedingly stupid this was. Had there been heroin inside that camera, you were going to prison for the rest of your life. They didn't (and still don't) screw around.

I heard all sorts of stories. An Australian backpacker was caught at Korean customs with 50 Rolex watches stuffed in his shirt. He was sent up for ten years. Numerous young Americans and Europeans busted for drug smuggling were rotting in prison in Taiwan, Korea, and Japan. At the time, with these countries technically allied with us against Red China, execution was not a politically feasible alternative.

This Mule thing is just another respin of an old practice. Best to avoid.

The "clear as mud" answer from the founder "same as all OBCs" was a really weird thing to leave up to interpretation of the reader. Nowhere did the writer enlighten me about the actual rights of an On Board Courier. I found this article really lacking in substance, sorry.

Being alone and hiking and camping in the wilderness without human contact for longer period can be amazing experience. There can be initial anxiety and intense desire to go back after romance goes away and your internal shit comes to light. When there is constant need for do chores to survive but also free time and no human contact, no books, radio or music, mind gradually settles into itself.

It's like coming from bright light into a dark room. Gradually your eyes adjust and you start to see more. Coming back into the civilization is similar to someone pointing flashlight into your eyes. So much external triggers for behaviour. Realizing that I'm not actually me with other people and I'm disappearing into network of others. Me with others is mainly just bunch of triggers that fire based on conditioning.

If I can feel intense otherworldliness from just week or month alone, I imagine that if someone spends decades alone, civilization might seem like miserable alien ant colony. Everybody is responding to commands from others and carrying stuff they don't care about.

ps. It also can trigger psycosis, panic or some kind of madness (prairie fever, cabin fever) in some people. Romanticizing it as escape from all your problems might give people the wrong idea.

It baffles me that people think it's so shockingly outlandish that there are people who don't reactionarily buy into the tribalistic pressures around us to simply act like everyone else. Humanity is not homogeneous, yet some notions like these are always projected out to be considered an immutable, inescapable constant. I can only guess that's that same fear of being different shining through.

I presume that on sites like this, there's a higher percentage of people who attempt to be more intentionally decisive about themselves and their lives. We don't necessarily have to toss out everything like Knight did, but looking at life and all the weird social rituals and expectations built up, the dichotomy between those and what seems actually beneficial becomes apparent. That conflict causes a choice, we would seek to do the "better" thing, and that draws many people outside the superficial social norms.

I especially bristle at this quote: "Why dont we want to be alone? Because the stuff thats down there is stuff you dont want to see." Anybody who tries to intentionally better themselves knows what's down there. You have to assess what you are if you're going to change. Sure, you can deny and hide from all that and simply find comfort in floating along with everybody else in social inertia, but that seems to me to be a shameful waste of those conceptual abilities which (apparently) make us uniquely human.

I have the impulse to become a hermit myself, fundamentally because I'm tired of living up to other people's ideologies: going through schools and finding a job in a cubical. getting married at the right age and then raising the right amount kids, saving for their college fund and then for retirement.

but why?

I can't help but compare with my surroundings, even I have quit Facebook for many years. I can't be myself when I'm around others, but become a money maker for things I don't need. I can't concentrate on what makes me happy.

I recall what made me happy. it was when I finally understood some papers, some equations, some code. I just want to find a quiet place to do these. I hope to become an awesome painter and a guitar player too.

I just want to have enough to survive and focus my energy on these things. I don't care if I have successful kids or fancy cars.

The title IMO is far more interesting and thought provoking than the actual story. So this guy lived in the woods somewhat near people, and stole to get by...

I've personally always been fascinated by the topic as I have met several hermit monks, have a friend who lived as one for half a year, and contemplated it for myself. The history of religious asceticism and hermits is quite interesting, and many of history's most famous philosophers/religious leaders/prophets were either hermits, or had periods of reclusion. And nearly every single religion has these hermit figures.

Anyhow, the downside is that being alone is tough. Physically and mentally. Humans are social creatures. However I have personally benefited from periods of isolation and reflection, even if I'd much rather be around others.

> Years ago, I went to India for a ten-day, silent retreat. I wanted to make myself go where I was afraid to godeep down, inside my own head. I found it terrifying. Why dont we want to be alone? Because the stuff thats down there is stuff you dont want to see.

We live in a world in which who we are is defined by what we do. We are a role - parent, engineer, carer. Strip that away and all that remains is a who. That's the reward of solitude: a situation wherein you have nobody to bounce your 'self' off, nobody to define yourself in relation to, allowing you to surface.

Turns out that who you are is simply a sequence of reactions to experience - the external kind as well as that which bubbles up internally. Rather than terrifying, this should be seen as profoundly liberating.

The idea of introverts and extraverts being distinct groups of people with completely different neurological responses to social situations is a largely false one, created by self-help woo merchants to unhelpfully pathologise the feeling that EVERYONE has from time to time that they want to be left the fuck alone.

You know what? It's a normal, neurotypical part of life as a homo sapiens to want to be by yourself sometimes. And equally, it's a normal, neurotypical part of life as a homo sapiens to want to socialise sometimes.

We're a weird species like that, the way sometimes we want something and other times we want the opposite.

My personal theory for explaining hermits throughout history is simple, these people had/have aspergers. I have aspergers myself, and I can very easily see someone who has aspergers who for whatever reason no longer wants to socialize anymore getting up and doing their own thing out in isolation. I don't truly believe that any neurotypical person, and for that matter many aspies could do it, but if you're brain is wired in a way that socialization doesn't provide that reward that it does for most other people, either because you don't understand social interaction and have no desire to learn the rules so you can play the game, or simply because you have discovered the rules and simply have no interest exhausting the effort, going out into isolation and spending the rest of your days pursuing other things that give you fulfillment.

Snap Judgement did a nice podcast version of this story. http://snapjudgment.org/north-pond-hermit

The letters Knight & Finkel exchanged add an interesting angle.

Can't say I'm a fan of the author's choice for title of this post. It's Chris Knight's story, and nothing in this post presents any evidence for anyone else at any other time, aside from this single sentence "Think of Jesus, Mohammed, and Buddha: they all spent very long periods of time alone before introducing their religions." I totally believe there have always been people who want to be alone sometimes. Pretty much everyone wants to be alone sometimes. But ugh, this sentence & title seem to strain credulity and are so completely unnecessary and tangential to this story.

Its emotionally draining and stressful.Almost everything we do can be automated, but people still insist on face-to-face interaction(or at minimum voice/video chat) and there is this herding behavior that forces people to adjust their beliefs and thoughts to conform to current in-group paradigms(the comparison with ant colonies ITT is on point).All the 24/7 media exposure and rat race of consumerism eventually take their toll on mental health(the polar opposite of "hermit slowly losing their minds") with people becoming psychotic and dependent on pills to function.

Okay, I've been watching this for a few minutes, and... the 8 second delay is FAR too long.

Doom is simply too interactive. You need to be able to control it in realtime.

I recommend three things:

- Slow the delay right down, and possibly make it adjustable via chat commands. A 500ms-1s delay is honestly going to be the best possible thing here. Yes, some players will lag too much and won't be able to play at those latencies - which is why you make it adjustable.

- Show, inside the video stream, the command that is currently executing, and the username executing from. This will create a unique tuple that will allow players to figure out the sync for themselves.

- A consensus system that tallies up the next key to press, TpP-style, might be a good idea. Right now everyone's fighting to cooperate because it's concatenating everyone's actions together.

"I ended up between the Supermicro SSG-6048R-E1CR60L or the SSG-6048R-E1CR90L the E1CR60L is a 60-bay 4U chassis while the E1CR90L is a 90-bay 4U chassis. This nice part is that no matter which platform you choose Supermicro sells this only as a pre-configured machine this means that their engineers are going to make sure that the hardware you choose to put in this is all from a known compatibility list. Basically, you cannot buy this chassis empty and jam your own parts in"

This is a major departure from the Supermicro business model and practices and basically broke all of our next generation expansion roadmaps.

This was not a technical decision - it is the same old economic decision that every large VAR/integrator/supplier has succumbed to for the last 30 years. They aren't the first ones to try this trick and they won't be the last.

We (rsync.net) are not playing ball, however. After 16 years of deploying solely on supermicro hardware (server chassis and JBODs) we bought our first non-supermicro JBOD last month.

There are a couple needful tweaks to this BOM for anyone wanting to follow this..

Only populate one CPU socket. Zone allocation between two NUMA nodes is kind of hard, especially since Ubuntu 16.04 zfs is pre- OpenZFS ABD where memory fragmentation is reality.

I would recommend better NICs like a Chelsio T5 or T6. Aside from better drivers and a responsive vendor, you can experiment with some of the iscsi offloads or zero copy TCP.

Supermicro seriously under-provisioned I/O on that chassis. I'd add LSI/Avago/now Broadcom cards so you can get native ports to every drive. Even if it's just a cold storage box, it will help with rebuild and scrub times and peace of mind. The cost of this is not bad compared to the frustration of SAS expander firmwares. 2x24 or 3x16 and 4 drives on the onboard if you can skip the backplane expander. Supermicro will usually do things like this if you insist, or an integrator like ixSystems can handle it.

More subjectively, I would also recommend FreeBSD. It seems their main justification for Ubuntu was paid support, which can be had from ixSystems who sell and support an entire stack (Supermicro servers, FreeBSD or FreeNAS or TrueNAS, and grok ZFS and storage drivers to the tune that they have done quite a bit of development.

Zfs on linux and huge single servers, what could go wrong?

It's like a blog written by a 22 year old straight out of college that's never dealt with a real production deployment/failure

Zfs on Linux has data loss bugs. There's at least one unpatched and there are bound to be more.

Single huge servers eventually fail. Maybe it'll be a drive controller. Maybe it'll be CPU or ram with bit flips as a side effect. Downtime would be the least painful part of the eventual failure.

The most important line for me was "Today, you can run ZFS on Ubuntu 16.0.4.2 LTS with standard repositories and Canonicals Ubuntu Advantage Advanced Support. That makes the decision easy."

Its highly interesting that Canonical does this with ZFS. I'm not sure why they dont market this more.

Wow, so many wrong things with this answer...

Of course, it would not surprise me to learn that measuring IQ as a predictor for success (or at least what a measurer defines as success) is much more accurate than "measuring" EQ for the same purpose. It makes sense - IQ is demonstrably measurable while EQ is some vague concept "popularized by a journalist". However, to go from this to a broad statement that there is no such thing as EQ is just silly. You could just as well say that there's no such thing as beauty because there is no accurate test to quantify it.

For a simple demonstration that EQ is an important quality for prediction of "success", just think of all the successful people you know and ask yourselves whether you think they would be as successful if they had the emotional makeup of an 8 year old.

This Quora answer has too much of a "trust me, I'm an authority" vibe to it

edited: ok, removed stuff that upon reflection does not contribute to the discussion - my apologies for that. The main point however stands. The repeated claims of no such thing as EQ should be qualified with "in the field of psychology" - in that case, I have no objection to the answer.

This is super interesting but

 due to the per-CPU inode table structure, it is impossible to move a NOVA filesystem from one system to another if the two machines do not have the same number of CPUs.
seems like a dealbreaker. What use is a FS if it isn't portable? At least it sounds like they're very aware of this issue.

I'd be very interested to see what they end up doing to make this behave better prior to upstream consideration. I wonder if a linked list journal of inode table changes (with space drawn from per-CPU freelists) would be safe/fast enough. That could be periodically coalesced and remapped to the NOVA device's non-CPU aware inode table.

I was born and raised in Puerto Rico, but left to work in tech. As with any place, there's some good points and there's some bad points. Below are some points that someone moving to Puerto Rico might want to know.

In my opinion, their greatest achievement has been in its educational system. Despite its huge list of problems, UPR enables people of any background to receive an affordable high quality college education. In the US, you're basically forced to take out huge loans that might take decades to pay off. This should mean you'll get access to lots of highly educated individuals, although I don't know if that's the case in practice.

One of my biggest complaints is its poor representation in the US government. If you're living in Puerto Rico you can't vote in any of the US's elections, even though the actions of the president and congress could potentially affect you. e.g. You could get drafted and sent off to war.

Puerto Rico has its own constitution [0], which arguably grants stronger rights to its citizens than the US constitution. For example, wire-tapping is explicitly illegal. It also includes entries allowing employees to organize into associations and collectively negotiate with their employers, as well as go on strike.

An interesting point is that everyone is required to get a voter ID in order to participate in an election. This isn't seen as a problem, and getting one is incredibly easy. I found it incredibly surprising this wasn't the case in the US.

Food is amazing, but there's very little variety. Since there's so few people from different cultural backgrounds, you mostly get the same templates repeated everywhere. In the last decade it has been slowly improving. If you're a vegan or vegetarian, or if you require a gluten-free diet (i.e. coeliac disease), you'll have a hard time eating out.

Due to cabotage laws, you can't import directly to Puerto Rico. Everything has to go through a US port, which translates to increased costs.

Shipping stuff to Puerto Rico is usually more expensive than shipping stuff to the contiguous United States. I'd guess it's comparable to Hawaii.

Even though both English and Spanish are considered official languages, you'll have a very hard time living there if you don't know Spanish.

The question is not correctly formed: what we really want to know is if there are life-like beings that could operate on a totally different scale than ours (both time and size wise, including viruses and whales here). Self centered thinking, i.e. restricting our inquiry to only include protein-based lifeforms or other qualities required on our scale obviously prevents us from having the required open minded mindset.

It's answer of "No" is predicated on two assumptions: that the lifeform is not colonial in nature and that time is not a localized phenomenon. While on the surface that later assumption might sound absurd, our universe could very well be a Local Bubble of time. Time could even be a biological function of a higher dimensional being that is the size of the universe. There is also no way to disprove that without observing beyond the universe, which may get a bit dicey.

It's a thoughtful article, and I love the reference to Burroughs' Soft Machine. But it doesn't distinguish clearly enough between self-conscious organisms and the rest. It's true that consciousness and evolution thereof likely crap out when latency goes over a few hundred milliseconds.

However, I see no limit to the size of zero-gravity organisms like the honey fungus. Fungi are filamentous, so there's no unsurmountable problem with heat dissipation.

And even for self-conscious organisms, I can imagine hierarchical organization, such as Rajaniemi's "metaself" or Watts' Bicameral Order.

Since proteins cannot exist in space, then, using the currently accepted definition of "life" at the basic level as the complex of processes that allow protein molecules to exist, then the answer must be 'no'.

On the other hand, it is an interesting mental exercise to also consider other reasons why such creature might be impossible. One reason could be because the time needed for such creature to grow from something much, much smaller (as it usually happens in biology) would be longer than the age of the universe.

Another one is that nerve impulses travel slower than the speed of light, and so, again, it would take forever for a signal to reach the central nervous system. One could argue that the creature can be "decentralized", i.e. look more like a large colony of smaller organisms, but then the question arises as to what makes it a single creature in the first place.

Yet another issue concerns what drives the evolution of this particular species, and, again, the time it takes.

So far, all these considerations unavoidably lead to the answer 'no'.

When thinking about such things, you've got to ask yourself: under what circumstances would such a creature appear and under what circumstances could it die? What does it need? What constitutes a good or bad thing for it. How does it learn? How does it perceive? How does it act out its intentions? Does it have a self preserving instinct?

It doesn't make much sense for a creature the size of the galaxy. If it did, it would be extremely slow and alien to us.

A more plausible way would be if a human-scale civilization would create self replicating probes that would spread in the galaxy and bootstrap some sort of large biological or AI civilization.

A bit of tangent -- the article talks about powers of ten, and hints at how powerful a tool it is for analyzing everything around us. This resonates very strongly with me. The entire known universe, from the smallest particle to the width of the cosmos itself, fits within several dozen points on this scale. It's incredible.

Personally, the last few years, I have felt that working to understand how all phenomena can be sketched out on the log scale has helped me gain a deeper understanding of the world. Of course, this goes hand in hand with related ideas, such as having a generally skeptical mindset, seeking first principles, etc.

These ideas has been very powerful for me, and I thought it might be worth sharing.

P.S. the book "The Black Cloud", mentioned in the article, is a really fun and quick read. I recommend it for any sci-fi fans.

Then maybe if something like Von Neuman probes existed it could have colonized the whole galaxy (actually it could be done in a few hundred millions years) then those probes, while each one have is own brain, could communicate with the other probes and even if two probes at two opposite sides of the galaxy couldn't communicate, they would still be connected. Then maybe this network could be consider as a living creature.

It's a different topic, but related. I was marveling at the diversity of life on Earth, which led me wonder: to what extent does sustained life on Earth depend on that diversity? I.e., what would be required or different for a planet to host and sustain a single species of life?

Given the nature of evolution, and that one subscribes to it, life on Earth started with a single organism that replicated. From that point until a replication modified the organism into a different species, there would have been one species. But was it necessary to have multiple species in order to sustain life?

So this requires a few things,

First off, single organisms can have pretty advanced local processing of control. An octopus has a nerve cluster for each tentacle that can operate independently of the main brain [1]. So in at least one case, biological brains delegate work out to another region of the body. An argonaut octopus actually detaches part of it body, which as far as i can tell, keeps living for a while. it's kind of creepy. The only thing i can't find an example of, is remote control. A detachable body part, with a nerve cluster, that responds to light or sound seems like what would be needed for the base creature. Evolution hasn't stumbled on that trifecta here on earth. But it sure seems like something that could have come about.

The latency argument isn't compelling. If i can send one message, i can send another hundred billion messages along with it. So, sure only a few thousand round trips, but a fabulous amount of information transferred. There's no actual biological equivalent to a semi autonomous drone, so i'm not sure what that would look like before the creature took to the stars.

There's also no real obvious way for this lone detatched tentacle to consume the resources of a planet. But whatever. I think one entity with those three features might have a chance.

Also, is the creature smart? Does it get to genetically engineer itself? do cyborgs count? That greatly simplifies things as well. The detachable parts could have detachable parts, and recurse down to whatever arbitrary degree is useful.

Alternatively if you admit superorganisms, then everything is much easier.

So anyway, you don't really need to send many messages when the message is "here are the latest designs for industrial architecture to dismantle a solar system and send the resources back" It's up to the billions of lone tenticles and their machines to execute the will of the super brain.

On the other hand, yeah, there's not going to be a galaxy sized amoeba or panther or anything like that. maybe an incredibly fine mist of fungus or mold, but i think it'd be too hard to keep a system like that from collapsing in on itself from too much mass. a galaxy sized ring of spider silk orbiting a black hole sounds like great science fiction. but i can't imagine that working.

This article does not take into account quantum phenomenon. It's possible that instead of being limited by the speed of light transmissions, such a system uses quantum phenomenon for communication. Which then would make the whole argument that this article makes invalid. It's based on the premise that life would be based on the same sort of physics as life on Earth... which does not make sense as such life if it exists would evolve using a different set of rules which would include things such as limits on speed of light transmission in such large systems... so it would've learned to exploit quantum phenomenon for transmission.

edit:

Superluminal, or faster than light, communication is said not to work because it allows information to be sent into the past. There is however non-locality which is not the same thing. Sorry not an expert on this, but this seems to apply to the exact discussion.

The core idea is nice (using simple markup instead of code), but it seems developers these days are completely oblivious to the fact that HTML is extensible and was literally designed to do this kind of stuff. Markdown is better for simple text editing, JSON is better for simple data structures, but HTML is far superior for complex documents where you need to attach structure and behaviors to text.

Things it buys you out of the box:

 - No need to write a parser - You can make complex references via CSS selectors - Your structure (tags) has structure (attributes) - All the existing tooling will help you to debug if something goes wrong.
On this note, I regret that HTML5 had thrown away the good ideas from XML (syntax consistency and namespaces) along with the bad (weird sub-formats, entity definitions, directives and other complex crap no one used well anyway).

Here enough TLDR so that my comment makes sense: In the tropics, the distinction between agriculture and hunter-gathering less sharp than in temperate climates. Thus early signs of tropical agriculture (from 20-30 kyears ago) pre-date the traditionally understood rise of agriculture about 9 kyears ago).

This confirms my Sri Lankan bemusement at the term "temperate climate". The tropics can be a PITA in many ways, but they have no shortage of biomass. Subsistence gardens abound and are productive. Even more than in other gardens, the issue is less to make things grow, but to stop the wrong things from growing. It's hardly surprising if ancient jungle dwellers long ago to tilted nature's bounty in their direction.

But I do take exception to the somewhat hippy-dippy claim that ..."colonial, industrial societies" came from outside the tropics and tried "to practice monoculture, pastoralism, and urbanism within them." Those "evils" took place in the tropics for thousands of years before western colonialists turned up.

This was the truths scientists had discovered and it was unquestionable. It was printed in books to last forever.

But you grow up, and you realize that these things are malleable. It's more like as of 1998, Lucy is the oldest human remains we discovered, using x method.

I'm not saying it's a conspiracy or anything, but I think we should leave a little wiggle room in the way we make these statements from now on.

Off-topic, just had this (micro)-epiphany that I wanted to share:

It is well-known that a majority of programmers dread mathematics beyond something basic like high-school math, sometimes even less.

What these programmers don't know is that a significant fraction of mathematicians (probably majority of them) who haven't been involved with programming, computers, computer algebra systems etc, have a similar dread about programming, in addition to the envy of programmers getting paid at much better rates.

It's also said by many, though without universal consensus, that programming is more rigorous than mathematics (here 'rigor' means mathematical rigor, nothing to do with everyday usage of the term).

When you start as a math major after high school, you take computational classes like calculus and linear algebra. Then you move on to theoretical stuff and "high mathematics" like real analysis and abstract algebra. Then, at an even more advanced level, you get into logic and foundations of mathematics, and at some point you get familiarized with the concept of constructive mathematics.

What I just realized is that programmers are essentially doing constructive mathematics (as well as logic, to a fair degree) all along, without realizing it, the moment they start coding!!! and yet the same programmers dread mathematics. That is funny (although not to say it makes it any easier for those programmers to learn all the rest of mathematics; IMO mathematics is still harder than programming as a discipline).

I think this is one example of many, I've found over the years but can't recall of the top of my head, where an expert of a given discipline is so encumbered by the "underlying machinery" of their field, that they fail to see that once they reach a higher level of abstraction, it sometimes becomes easier, rather than harder, if you forget about the details while working at that level, or you hadn't gone through the harder path to get there.

Another example being electrical engineers toiling through the difficult issues of power electronics, analog and digital design, computer architectures, instructions sets, only to find out that computer science people, who don't know all these things, have a much easier time working at the assembly language level, and those who don't even know assembly-language either, have no problem just sticking to a higher level language like ruby, javascript, and not worrying about or even aware of how the whole machinery works.

The study method seems to be "rate the letters by how much you like them".

While it looks like the study has been repeated enough to not be total quackery, there is still the question of what's the point. Does your preference for a particular letter has an effect on your choices?

I doubt the research about people preferring brands with the names in their letters has properly ruled out other variables, or would prove to be significant.

How many people actually give thought about what letters they like the most? I'm guessing the study was the first time the subjects were ever exposed to the thought of liking a letter. As such, ot seems reasonable to go for some point of reference that is simple and available, auch as your own name.

You get hexagons because of close-packing.[1] Circles (or a 2D array of spheres) of the same size fit closest together when they are arranged in a hexagonal pattern. Push a bunch of marbles together and that's what you get.

The bees don't know anything about hexagons. They just make circles close together and then as the cells are filled, stepped on, and come into contact with other wax cells, they "ballon out" into a hexagon shape.

I felt like the attack on "traditional" emotional intelligence in the beginning was contrived and not really thought through.

Yes, it's true that we assume we can approximate the emotional experience of others, but I think a critical piece the author left is the verbal part of emotional intelligence - the words someone says that convey nuances that facial expressions/non verbal cues don't. And I'm not saying what a person says is what they really mean. You need to be cognizant of both to hear the "real message". That's at the heart of emotional intelligence. I feel like the beginning was just a contrived critique made to draw the reader into the meat of the article. Can't we just examine the existing literature and add our own thoughts without suggesting some grand "rewrite"?

Also internal and external emotional intelligence are very different, I feel like somewhere the author conflated the two without making a clear distinction although maybe I just didn't read it deeply enough.

That said, the discussion on emotional granularity is very interesting and I will definitely be reading more into it.

> How do you enable your brain to create a wider variety of emotions and improve your emotional intelligence? One approach is to learn new emotion words. Each new word seeds your brain with the capacity to make new emotion predictions, which your brain can employ as a tool to construct your future experiences and perceptions, and to direct your actions. Instead of perceiving someone as generically glad, learn to distinguish more specifics. Are they overjoyed or contented or grateful? Are they angry or indignant or resentful or bitter? More fine-grained emotions allow your brain to prepare for an array of different actions, whereas more generic emotions (angry, glad) confer less information and restrict your flexibility.

This part makes me very leery of the strength of any claims in the article. The general phenomenon of neuroplasticity is not evidence that any particular intervention will do what somebody claims or expects. Quietly jumping that gap is a favorite method of peddlers of neurobullshit. Dr. Barrett has certainly earned a bit more benefit of the doubt than, say, Lumosity, but that doesn't make this particular line of argument any less grating.

This is a very interesting article. However, I wonder if/how the concept (or skill) of emotional granularity can be obtained only from learning new words for emotions. It kind of reminds me of NLP (Neuro-Linguisting programming).

I'm also surprised to hear that there's scientific consensus that thought does not have an inhibiting effect on emotions. I wonder how that comments on Daniel Kahneman's observations of interacting system of cognition (System 1 & 2), where one may block the other? Is the author also saying that beliefs can't be changed to ultimately have a causal relationship with emotions?

xxxdarrenxxx 10 hours ago 2 replies      
I personally believe a lot of this can be learned like any other skill. You just need to approach it differently and actively, not passively.

That said, I think it's slightly overrated, because most people don't even understand their own emotions, and some don't even allow themselves to talk about emotions/cry in presence of friends/other's.

So if one doesn't even understand, allow or acknowledge his/her own feelings, how could one possibly begin to understand, observe or manipulate that in other's with accuracy.

And actually that's not even fully true.. (this is why I think it can also be learned) Someone with anti-social disorder (sociopath), contrary to popular believe has the same emotions as everyone else. It's their empathy which is less/nonexistent. Yet they tend to be very good in picking up nuances in social settings and perform on them.

A lot of it also depends on personality/upbringing. Parents who lie a lot to their children, potentially makes these children more apt in lying/bluffing and giving false trust themselves when they grow up, which is still a form off emotional intelligence, morality is a different aspect.

Another example; One with social anxiety could very well have a high emotional intelligence. They naturally spend way more time focusing on nuances of themselves as well as other's, as the innate fear will push their thoughts constantly (with all due respect to people who experience this)

So almost ironically they might be socially less present, but probably spot true feelings far faster and more precise than people who are more "in the moment".

* a small anecdote*

I spend a few years giving music lessons, and I told a student I could teach him to just hear the music then be able to play it by ear. They almost all said "I am not born with good ears".

I began to pick a guitar and play a few notes off a famous song. They recognized it as anyone would.

Then I played a song but played wrong notes randomly. He didn't spot the first one, but then he noticed.

I asked him, how did u know the song and recognize the wrong notes if your ears are shit? he laughed.

Thing is, our senses are all very good, everyone can hear when singers are out off tune, anyone can recognize a person by a voice or most songs by melody.

You just need to learn which sound fits which spot on the guitar, like pictures to words.

The hearing, just like empathy, or sight and smell for that matter is there, or will naturally develop if actively used, and more efficient with added knowledge and guidance.

It seems to also be a sort of repl or something that evaluates the code you write as you write it maybe? I'd have to look at this from my computer to understand, but it's not what I expected from the title.

Detecting Chrome headless antoinevastel.github.io

Your solutions in detecting Chrome headless is good.

But someone who really wants to do web scraping or anything similar will use a real browser like Firefox or Chrome run it through xvfb and control it using webdriver and maybe expose it through an API. I find these to be almost undetectable.. The only way you can mitigate this is to do more interesting mitigation techniques. Liie IP detection, Captchas, etc.

edit: when I say real browser, I mean running the full browser process including extensions etc.

I really don't think scraping should fall onto that list.

There isn't even a consensus in the IT world whether or not scraping should be able to be legally restricted.

So again someone wants to punish all the legitimate people using a web site to get some marginal benefit from detecting the remaining <1%. The inevitable false positives don't affect the "malicious" users. Only the legitimate ones.And how much will this bloat the page load by? Adding more code to an already overly large page isn't helping anyone.

Just let the web be the web, and stop trying to control it.

This looks like a list of bugs that need fixing; ideally, headless Chrome should be completely indistinguishable from ordinary Chrome, so that it gets an identical view of the web.

Leaving aside for a moment that many "malicious" use cases are actually fairly common and totally legitimate.

Headless Chrome is awesome and such a step up from previous automation tools.

The Chromeless project provides a nice abstraction and received 8k start in its first two weeks on Github: https://github.com/graphcool/chromeless

I do hope that these methods get patched, I tend to archive my bookmark collection with chrome headless to prevent loosing content when such a site goes offline. I hate it when a website requires me to play special snowflake to scrape them for this purpose.

I guess I disagree with the premise of this article.

How is web scraping fundamental malicious?

What rights/expectations can you have that a publicly accessible website you create must be used by humans only?

> var body = document.getElementsByTagName("body")[0];

You can just use document.body.

I also suggest to use a data URL instead. E.g. "data:," is an empty plain text file, which, as you can imagine, won't be interpreted as a valid image.

 let image = new Image(); image.onerror = () => { console.log(image.width); // 0 -> headless }; document.body.appendChild(image); image.src = 'data:,';
> In case of a vanilla Chrome, the image has a width and height that depends on the zoom of the browser

The zoom doesn't affect this. It's always in CSS "pixels".

Multiple dispatch is trivial in C++ using overloaded functions, the compiler will select the most specialized version for the supplied parameters without any visitor tricks. The "problem" is that it doesn't play well with polymorphism since it can't trigger specialized overloads for base class pointers/references, I think the real problem is polymorphism.

I have trouble understanding this mindset. It's like, if you were walking away from your car in a parking lot, and someone said "Hey! You've left your car unlocked!", and you yelled at them angrily "Stop looking at my car!!!". It makes no sense at all, and yet it's practically the universal response from people who don't know what they're doing.

People occasionally suggest that software engineers should be professionally licensed. I have a different proposal: I think that people who want to manage a business involving software development should have to get trained and licensed.

ETA: while my proposal is somewhat facetious when considered about all software development, perhaps it's not completely inconceivable that we could require businesses collecting any personal information from users to be licensed and audited. We already have PCI-DSS compliance rules for businesses using credit cards; this would be analogous, though it would have to be enforced by the government, as credit cards wouldn't necessarily be involved.

Heh! Nothing new in the behavior.

Mr. Feynman famously found you could lift the combo off a safe [with the a-bomb's secrets] when it was empty. When he alerted the Colonel not to leave his safe open, the response was to:

send a note around to everyone in the plant which said, During his last visit, was Mr. Feyman at any time in your office, near your office, or a walking through your office? Some people answered yes; others said no. The ones who said yes got another note: Please change the combination of your safe. That was his solution. _I_ was the danger!

Putting text on a page isn't hard stuff. The hard stuff is teaching computer security to an organization that mistakes responsible disclosure for a hack attempt, and thinks a Twitter block will protect them.

It's probably also hard to know what a good security audit looks like, unless you grasp basic security in the first place.

I have no idea what the solution is.

After so many decades in this industry nothing surprises me at all. Security is usually an afterthought that barely warrants spending more that a token amount. I once did a contract at a public university and found the app that every department used to verify with the state that money was appropriately spent used incrementing id's in the url and used GET to handle the delete button. I wound up fixing it for them on the way out (after weeks of telling me it wasn't a concern). A simple command line script would have deleted the entire database leaving the university with no budget for the upcoming year. Another place I worked kept production passwords in the code repository; when I complained they told me they passed their audits every year so it didn't matter. HIPAA company in the US no less.

So he answered along the lines of: I grew up in such and such home, my experience is totally different and I'll be happy to buy you lunch.

Answer: blocked.

Blocking is a power thing for some people. IIRC it used to be a thing in the old Usenet and of course it existed before that in other forms.

The solution to this is simple. Disclose everything. Have these companies destroyed. Have everyone who works for them fired and become unhirable. Have their houses foreclosed on because they cannot afford to pay the mortgages or rent.

That's the only way to ensure that the security is taken seriously.

Paranoia apart, I'll tend to agree with other comments here.

A device like Google glasses, well why not after all, since you can choose to put them in a drawer (not debating on the fact that you potentially record other people, which is really bad). But having a device you might loose control over and can't switch off ?

It's like those webcam on laptop that can be switch on by a hacker or your OS without you knowing it. First thing I do is to put a paper on it.

Security matters. And I'm finally perhaps a bit paranoid after all.
