Well, plenty of traders are out there selling without actually owning -- that's something market makers and only market makers are allowed to do, and it's certainly possible that market makers algos were selling too low along with high frequency traders.

But regardless, when you have a derivatively priced security like RSP (which holds actual stocks -- it has some inherent worth at all times that's knowable) any selling at a discount is supposed to be arbitraged away. In these cases, it wasn't,because the trading windows were too short.

Docs Without Borders: Sync Google Docs to Your Dropbox
The single stock circuit breakers were put into effect after the 2010 "flash crash" and they're designed to "let cooler heads prevail" when stocks or ETFs go wonky. The problem is that in a real panicky freefall, it just makes the window where the stock is trading very very small (it halts for 5 minutes, opens, hits the next breaker, halts for another 5 minutes, etc.)

It happens both up AND down. This last monday was really the first time they'd been tested en mass.
Google OnHub Review
One scenario would be to gum up the market during a volatile time - eg to retain "value" while investors are panicking.

But I would lean towards the halts being an unintentional (as in: not well thought through) consequences of all the layers of regulation and counter-regulation.
Microservice Architectures aren’t for Everyone
After $2.5B buyout, Minecraft creator has never felt more isolated
So Mesos 0.23 (current stable) supports the FrameworkInfo for dynamic reservations and persistent resources (https://issues.apache.org/jira/browse/MESOS-1554). This allows for a framework to request that a chunk of disk space is persistent and if the process is killed, it gets restarted on the same mesos slave (assuming that slave is still online).

Now if I remember the talk from MesosCon this year correctly, 0.24 will have the quota integration with the persistent resources, and 0.25 will have the administrative api additions. With 0.25 admin tools can be written to manage the persistent resources manually.

Like Mysos does currently, your best bet is streaming replication and persist snapshots to a shared filesystem such as HDFS. Unfortunately, until all of the persistent resource bits are fleshed out a bit more, that is your only option.
What is exactly wrong with piping curl into bash? I'm trusting RVM anyway. As for functional package managers, I'll believe it when I see it. The reason things are brittle is that any time something in the middle of a dependency chain changes the whole chain may break. The more you freeze things, the greater chance there is to freeze up a security hole (see what is going on with Docker). So you have two choices: be ok with the freeze, or update the whole chain. In this respect I prefer the latter, and I especially prefer the way Ruby does it where, due to the global namespace, I'm forced to upgrade the gem everywhere so I end up fixing things and keeping the whole project up to date. While this seems frustrating at first, once you realize that everyone in the Ruby community is doing it, you realize that the reason it is usually painless to update your gems is because other people have fixed those other holes. What is especially nice is that you only have to remember things that are broken at T0, unlike, say, Node, where a popular nested node_module may have 10 different versions in your dependencies and you keep hitting the same bug or security hole over and over again.
You make a good counterpoint, for barbershop. It's definitely a form designed to bring out the effect of these microintervalic adjustments. Of course, those cords are sung in just intonation, not well temperament :)

I probably could have phrased my comment a little bit more delicately, but my point was in reaction to the article, not the overall concept of tunings and temperaments. What drives me nuts are these "you're doing it all wrong" types articles about something that really makes very little difference to most people. Especially this one, in which the author really didn't bother to provide any auditory demonstration of a purely auditory phenomenon.
Actually, as I mentioned, /tmp is (AFAIK) everywhere a tmpfs mount, which means these files are kept in RAM and stored to disk only if their pages are swapped.

I call bullshit. Given how little a department actually spends on employees that report to PIs, it would be interesting to know how this happened! Further, H1B is not a zero-cost or low cost proposition for universities and departments, especially for short term appointments! He said she said can provoke discussions, but should also be viewed with skepticism! It might work for large companies because the upfront cost ($10k attorney, filing, etc.) amortizes over the several years the h1b is likely to be employed.

Javascript minification seems like a classic case of premature optimization. I'm not a front-end developer so maybe I'm missing something, but wouldn't simple, transparent gzip compression via your webserver — one line in a config file — get you something like ~90% of the benefits of minification, for free?

I'm sure there are some additional gains to be made from knowing the syntactical structure of the language you're minifying, since no generic compression scheme can know that. But that seems really marginal — and, as the article in question shows, opens up potential security vulns.

A stop with a limit is perfectly fine. It's essentially saying "If the stock trades below X, sell it, but not unless its above Y." So if you bought at 80, its now at 100, and you want to make sure you make some profit, you could put in a stop loss that was at, say, 90/85. So you sell if it goes below 90, but only at better than 85.

The issue there is that in a fast moving market, you might not get filled. When the stop triggers, the order "becomes" another limit order in the limit order book, and if the market's already moved bellow your limit, you dont execute.

Also, Market Orders are ALWAYS executed before limit orders, even if the limit makes it executable. That's just the priority system of the market.

Hmm ... I am very skeptical when people report numbers of 350-400K. Apart from Netflix, which claims it pays at the top of the market, I didn't think other companies paid this much in base salary to mid-level tech employees. Glassdoor, etc. suggest the numbers for base salary are closer to 150-170K.

I remember being a little bit obsessed with the "Nightmare" movies as a kid (like maybe around age 11-12). I think part of it was that those gory, R-rated movies were "forbidden" as they were meant for older kids and my dad didn't like me watching them. But a big part of it was the mix of dark humor and some of the more genuinely frightening concepts I'd ever seen in a monster movie at the time.

Admittedly my experience with the genre was limited at that age but up until then, I just thought of horror movies as the stereotypical "stalking monster" type thing. Monster is out there somewhere. Protagonist has to escape the monster and hopefully learn how to kill it or at least stop it.

The thing that always got to me about those early viewings of the Nightmare movies was that the protagonists were teenagers (often troubled ones) so there was the element of "the grownups will never believe me". As a kid you're familiar with the disconnect between children and adults so that's already a source of anxiety that the movies tap into.

The other part was that you couldn't escape the Big Bad by hiding in your house or even in a fortress. Freddy came after you in your dreams and sleep is something you just can't avoid. So many times the hero would think they were safe only to see something weird happen and realize that they were still trapped in a dream. It was that sort of surreal, almost Lovecraftian idea of the sinister, evil reality that exists alongside this one which legitimately scared the crap out of me as a kid. I'm pretty sure that when I first watched those movies, I wondered if I'd have the courage to fight a "Freddy" or whether I would just commit suicide rather than live in a world with no certain realities where I was forever in fear of my life and sanity.

I think that's true; many people do avoid Ph.D.s because they aren't a good investment. Whether or not that's progress depends on your goals: if you just care about more people having more money, then sure, more Ph.D.s doesn't equal more progress in the short run.

But at least in the US, there's a huge problem that the problems we have that can be solved are increasingly technical, requiring more and more education. Meanwhile, the incentives we're providing incentivize not getting more education. If we're going to continue the charade that capitalism is meritocratic, we need to align the incentives with the needs of our culture and economy, or the results will be disastrous.
"Seriously, those things should just be banned from retail investment and retail investment education."

The problem is we aren't just talking about ETFs...there were similar effects happening in individual stocks where they were down much, much greater than this ETF. We should just ban stocks for retail investors?

What's wrong with people learning about things before they throw money into something they don't understand? Banning this and banning that blindly just makes people more dependent on someone else doing their homework for them. People need to take responsibility for their own actions and read up on stuff before dumping money into something.
Also, I forgot to point out, I have an autoinstall script for bmake and bsdowl, it is here:

https://github.com/michipili/anvil/blob/master/subr/anvil_travisci_autoinstall.sh

It will install both of them under ~/.local, so that you need to tweak your path accordingly, but you can choose another prefix with the `-p` flag, like

sh anvil_travisci_autoinstall.sh -p "${HOME}"

If you want to customise it, you can trim most of the script (autoinstall_opam*) because you do not need this. :) And if you need something more specific, just ping me on the issue tracker for instance. :)

I read, just recently, that they gave novices and expert players chess positions to remember. The experts remembered real positions better. There was no difference in recall between the experts and the novices when they weren't real positions. This suggests that the ability for recall is highly contextual.

I once had a silly argument with a hydrogen fanatic (who insisted he built a working hydrogen fuel cell in his garage in the 70s, but we'll get to that) which was back and forth like this:

Hydrogen Fan: But the exhaust is only water!
Me: All electric cars have no exhaust!
Hydrogen Fan: Well they do at the coal plants!
Me: So we are going to count electric production? What about Hydrogen production? Today it uses fossil fuels and outputs carbon and methane worse than coal plants.
Hydrogen Fan: But the real exhaust is only water! And you could eventually get the hydrogen back out of the water!
Me: That's not how Chemistry works. Where does the energy come from to split the water molecules?

That's about when I gave up on the conversation as it derailed into the aforementioned beliefs that the guy built a Hydrogen Fuel cell that somehow fueled on water, spit out water as exhaust, and was capable of driving a car in the 70s but then his garage experiments were stopped by a government conspiracy. (I presumed drugs were heavily involved in the actual reality of this story, this was a middle aged guy working in a hardware store.) This entire conversation felt like par for the course when dealing with people that think hydrogen powered cars are anything but a ruse. You even hear variations on it from the Big 3 car companies. ("Well we almost had hydrogen working in the 70s but the government stopped us." Yup, it was clearly the government and not, say, the basic laws of chemistry and physics.)

His essay "Sabbath" is a graceful look at what that tradition meant to him. It has inspired me to start a practice of "Technological Sabbath", putting away items of technology each Saturday evening at sunset and not picking them back up until Sunday at sunset. This has allowed me to focus more on family, friends and meaningful activities outside my normal viewpoint. Definitely recommend reading it and other works of Sacks.
And as someone who also was acquired by BMC, the interesting bit for me was that the acting CEO of Boundary was a guy named Larry Warnock, who had another company that was acquired by BMC, Phurnace, for what I expect is roughly the same amount of money as Boundary was acquired.

The whole point of the back-dooring js blog post was that you can create "deniable" bugs that are hard if not impossible to see by inspecting the unminified source, and can't prove intention. They already have great reasons to require source, so it's ironic this would be the catalyst to start, no?

This process has been going on for over a century. Ever since the introduction of the phonograph, the social importance of sharing music around a piano has been in significant decline.
Part of the benefit of minifying is obfuscating the code, the only way to strip out all meaning is to have a minifier that understands the syntax.
I'm a front-end developer and you are absolutely right.
How long does a piano last? Surely the market is saturated at some point, especially for extremely expensive pianos like these.

What i don´t understand is - there are arbitrage players, who calculate "real value" of the single stocks in each ETF. Aren´t they liquid enough? Because if they were, the price would not drop that much, would it?
I'd literally never heard of "Notch" until five minutes ago, and I'm a techie who obsessively follows tech news, so there are obviously innumerable people who've never heard of his "wide impact" and couldn't care less about it -- there's no barrier whatsoever to him living a "normal" life.
Well you can call bullshit but I have the math and you can't argue with it. The Post Doc was 1 year away from being promoted to Instructor, which meant they were at the upper bound of the Post Doc salary. Also, if the Post Doc was promoted to Instructor, they would become Faculty and would be unable to be shit-canned during a Reduction In Force (RIF) scenario. The Chair made all of this clear. So, if you're going to call me a liar, you can go pound sand because that's not how I roll.

Thanks to a little tool I found here on Hacker News, I was able to look up the number of H1-B Visa applications for this Top 60 Research University, and in one year alone, they applied for 70+ Post Doc H1-B Visas. Obviously they know how to pull it off.

Besides, everybody in science knows that students / Post Docs are expected to be like slave labor, and as many have pointed out, the conditions of the H1-B are extremely beneficial to the employer in the context of pressure to perform and retention. Skepticism is fine, but it's not bullshit. Your rebuttal is ineffectual and belongs in the circular file.
>For most people, they're not going to die or starve to death if their startup fails.

My wealth is pretty much the value of my home. Any risk to losing that is fairly serious. No, my family won't starve, but losing years of equity/value and being forced to move to a shittier part of town and shittier school system, more crime, etc is a demotivator. This is why you see so many startups being kids directly from college. They have much less to lose and they're still young and energetic and haven't been beaten down by the 9-5 grind yet.

>Pick your battles carefully, and never give up.

Agreed, but now I do smaller and less ambitious side-projects than a big dramatic "We quit our jobs and now work out of a garage" type startup stereotype. Its not nearly as sexy or potentially life changing as "I'm selling a small application that targets $boring_industry and solves $boring_problem, but may be a nice small passive income if things go perfectly."

I think using the term 'not sexy' to describe a nation that is undergoing internal conflict and massive economic contraction is using the wrong connotations. Refugees flee a terrible life to find stability. Not even native Greeks have stability. Clearly the EU refugee rules are not fair to border nations. It seems that yet again the rules of the EU benefit the richest, most powerful countries most.
Minified js doesn't need decompressing whereas gzip would, but I'll admit it's probably a minuscule amount of CPU even on a smartphone, especially if you cache the decompressed version.

If you have ADHD or are close to someone with it, do yourself a favor, sit down and watch this lecture series by Dr Russell Barkely: https://www.youtube.com/playlist?list=PLzBixSjmbc8eFl6UX5_wW...

It's geared a little more towards childhood ADHD, and it's quite long (I needed to be medicated in order to watch the whole thing, of course..) but this Dr is a fantastic expert on the topic and doesn't hold back on explaining the disorder in clear medical terms. He also does not sugar coat anything or tell you what you want to hear. It's a very pragmatic and thorough explanation of what ADHD means, and really opened up my eyes in many ways.

One of the important takeaways from that lecture is that ADHD is not simply attention problems, there are a myriad of related issues with executive function that are just not as apparent. Learning that ADHD is more than attention can fundamentally change your coping strategies. Well worth investing time into deeper education
Not to mention that Mitsubishi and others are working on good solutions for inductive chargers that could be mounted into the street, making the parking spot itself the charger, at which point nearly every parking spot in a city has the space to be electric (it just needs the infrastructure investment).
