> I'd be more interested in understanding the long-term effects of insufficient sleep.

I will confidently guess it involves more infections/sick-days. More zits, and general inflammation. Higher cortisol/stress/angst. Higher rates of gastro-intestinal complaints (IBS, heart-burn).

If I skimmed the article correctly it measured ability to concentrate for a short time exclusively and ignored these others metrics.
Where has anyone ever said that a sentence cannot be started with "however," which is an adverb?
This is my favorite quote about market research.
Ask HN: Would you pay for daily motivation? Personal trainers for goals?
People on this site always talk about having people that you don't want to let down. I'm thinking a daily call, email or Skype for a few minutes with someone with the aim of them making sure you work towards your goals!

Kind of like personal trainers, except for your goals.

if you want to play in HFT you want 1) wicked chops 2) collocation with exchange computers to pick up nickels faster than anyone else (was going to say sub-millisecond but my knowledge is not that granular) 3) access to historical tick data to analyze, which is expensive to subscribe to and manage (was going to say petabytes but my knowledge is not that granular)

The way to think of a big part of HFT is really just automating the old function of market-making, adjusting the bid-ask on many securities to keep things in line.

In the old days if you wanted to trade, you called a broker who took it off for a price, the bid-ask, and you tried not go get ripped off too much. Now institutions who want to trade look for ways to feed them into the maw of HFT without getting ripped off too much, and HFTs try to figure out how to get as much of a bid-ask as possible.

Surely the biggest consumers of processing power are the data centers of Google, Amazon etc... Places like Goldman have sizable clouds but I don't think they compete yet.
Seems useful.

Is there a way to integrate this with a development version of Django? I.e. the Client() is really useful to test the backend but it could be great to also use this library to test the front-end. I mean, it's a bit "late" to test the front-end if it's already live no?

No, you couldn't.

No Java compiler has ever generated the kinds of error messages that every single C++ compiler did for template errors. Feel free to give me an example of Java compiler error message that takes 2 screens and fails to give you useful information.

If you compared the complexity of clang C++ front-end with complexity of any Java compiler front-end, you would see a huge difference in complexity (size of the code, time it took to develop).

The first checkin in clang code base was in 2006-06-17. It took almost 5 years and more than 31 thousand checkins to get to current state which is: not done (http://clang.llvm.org/cxx_status.html).

A fully functional, fully compliant Java compilers have been written in fraction of this time by much smaller dev teams.

The facts do not support your claim that "proper design" is enough to write fully compliant C++ front-end in a reasonable amount of time. 5 years of effort of top-notch, highly paid developers to not achieve the goal is not reasonable and it's fully the result of C++ complexity.

You seem to be holding on to your established site, almost with nostalgia, and I can understand that, but that's not the way to be effective when it comes to building traffic. You have to be prepared to start out on the right course, even if it's new.

Try "inertia" and "lack of time/energy". I don't think nostalgia has any significant positive part of this. (I have lots of negative feelings about the kind of negative attention the site has gotten me, which is the primary reason I frequently consider abandoning it altogether.)

Again, thank you very, very much. I am working on some of these issues. This has all been extremely good feedback.
Wow, reading through that, and looking at Utropic, it's amazing how similar our projects were. We had many of the same aims, ambitions, problems, and results.

I think your analysis of the situation (No Co-Founder, Not fully invested) was true for both of us, but I also, particularly after reading your ioFeed post.. We're creating technical solutions to problems.

That's not enough. Saying "I can improve on Facebook" doesn't take into account the huge network effect, and it doesn't solve the problem of getting people onto your site.

It's a good reminder that the tech isn't enough by itself.

> It's okay for functions to have unknown behavior that I have to learn about before using them, because I'm used to that, but it's not okay for types to have any kind of unknown behavior, because I'm used to C,

It is not an issue of behavior but of understanding.

In C++, a large number of things can be happening in a single line: an operator being called, a type conversion, a template instantiation, an overriden function in one of a dozen of classes, a constructor called in some part of the hierarchy, in some namespace... who knows. You have to be smart enough to figure out what is going on in each of these cases. As you code base grows, this makes it increasingly hard to understand what is going on.
If my live front-end breaks, I certainly want to be the first to know that.

Yes. I have cron-jobs running tests on live sites looking for broken things.

I smell politics. This is the university equivalent of how municipalities cut police, fire, and teachers first, regardless of whether they are the actual budget problem. It's designed to get people screaming and get their budget restored so they don't have to make any cuts.

Barring sudden changes in the economy, though, this probably won't work to avoid cuts from the legislature. There's a lot of ways this could play out. I suppose my real point is to look to the larger picture; this isn't occurring in isolation and I think there's a great deal more going on here than just the first-order story.
One thing to always consider is that even when the housing market makes money there are ways to benefit from it without owning a house.

For instance, buy an index with a low maintenance fee that tracks the REIT. It's also a lot quicker (and easier) to get out of that index fund than it is to get out of your home. https://personal.vanguard.com/us/FundsSnapshot?FundId=0123&#...

The key is, you can invest in real estate without owning a home and better still: be diversified into multiple kinds of real estate. A home is a very homogeneous investment vehicle. Think of it more like a savings account with a maintenance fee but you can live inside it.
If this becomes common, it will certainly be a test of bitcoin's legal status. Seeing how the IRS and Social Security calculate what taxes, if any, you have to pay will be interesting...

Again all of this assumes unifrom distribution. The files used in dropbox are not guaranteed to be random or uniformly distributed. As I already said in my initial comment, various different files types have internal structures which may (again if you are unlucky) result in multiple different files of those types tending to have similar hashes.
Troubleshooting is just the art of isolation. You isolate areas of the system and experiment until the problem becomes apparent.

Why would I add 1.8K of possibly buggy minified code, compiled from 247 lines of possibly buggy un-minified code, to my web app, just in order to avoid having to write

function after(seconds, fn) { return setTimeout(fn, seconds * 1000); }
function every(seconds, fn) { return setInterval(fn, seconds * 1000); }
var MINUTE = 60, HOUR = 3600;

in my program?

I do like the naming and argument order better than the standard functions, but the cost-to-benefit ratio of this library seems off by two orders of magnitude, given the ability to get the same benefit in two or three lines of code instead of 200 or 300.

The only way out of this "Perfect Storm" is to empower the people with a tool that will allow them to use their skills, talents, abilities, and knowledge to make money. This would encourage and create skilled, smart, talented, and able individuals of any walk of life, compete with local businesses and other individuals for gigs, projects, jobs, and more. Something like that would balance the market and make it more efficient while giving everyone the opportunity to do the things they love and have a passion for. That is what we are working on. This tool is already available at http://www.hiredfor.com/
C++11 has made things more complicated, not less. All these criticisms are still valid and can be extended with some added new stupidities (for example needing to explicitly specify capture in lambdas, a new and entirely unique way to shoot yourself in the foot; or user defined numeric literals which brings the joys of parsing C++ down the stack making even tokenizing it difficult).
You don't take academic sites with paywalls seriously? You don't take O'Reilly subscription eBooks seriously? You don't take curated commercial data feeds seriously? You don't take licensed film/Netflix style sites seriously?

People want free information, but people don't act like free information has any value.

If I tell you about the feeling elimination technique, which is useful where you imagine a situation and feel a sudden physical feeling (e.g. imagine a being in an aircraft and feel your stomach tense up and you get anxious, or imagine eating fish and your face screws up in disgust, or imagine confronting someone and wanting to curl up and hide, that kind of thing).

That the technique involves imagining one situation hard, noticing the physical reaction in your body, focusing on what you're imagining to intensify the physical response - like grasping a nettle hard - then holding that state while counting backwards from your age to 0 (start in 5 year increments to age 5, then 1 year increments to age 1, then month increments to -9 months) and each time pause a couple of seconds and ask yourself if you still feel this way.

That's it. It exists, it works, if you practise doing it you can get rid of some kinds of automatic fears which have been a deep set part of your life for decades, and you can do so in minutes. This is free, potentially life changing information. I would bet money that you wont even try it, and think it probable that you wont even take seriously the idea to try it and plan to do so "one day" and never do. That nobody who reads this will give it a second thought.

But if you'd paid good money to meet a consultant about some fear you have, and they told you about it, you would think hard about it, try it, and when you fail the first time, you would try again. And if you can't do it, you would try a different fear assuming it was you at fault not the idea. But if it's free, you're much more likely to try it once and if you can't get it to work first time on one fear, assume it's bunk.
I didn't claim that Rösler is chancellor. In theory, he could still become prime minister of a state or chancellor. As you probably know the Green Party just got their first prime minister, so small parties can grow big. And really, going from 15% to 24% doesn't look that impossible at all. He is still very young.

Anyway, my point was, that place of birth plays no role in Germany. And, certainly the vice president must meet the same requirements as the president since he automatically takes over if something happens to the president. I think this true for most organizations, no?

I just forgot, that PG was English born. So this submission of mine was clearly bullshit. By the way I don't advocate that the US changes this law. I think there are plenty of good candidates anyway.
Debug.Trace, for instance.

More generally, the fact that execution time and memory usage (tail recursion!) sometimes depend on how well the compiler can turn your stateless algorithm into a stateful one, in ways that don't make sense from the perspective of the abstract machine.
Myth: Digital signals can't degrade except in an all or nothing way.

Simple experiment you can do at home: Take your favorite audio source, convert to uncompressed 16-bit samples (just like you'd find on a CD), and clip the high bit to always be 0. Congratulations, you just degraded a digital signal.

Oh, the article then says "While processing artifacts can occur and gaps in the signal can cause blocky effects". If that isn't gradually degrading, what is?

"it's like saying you can get better-looking YouTube videos on your laptop by buying more expensive Ethernet cables." Anyone who's ever used a damaged ethernet cable before knows how wrong the author is on this point. It doesn't take many dropped packets before you can't stream HD video.

I 100% agree with conclusion, but there's something about the words "digital signal" that somehow makes people think they aren't signals.
When you are talking about longer distances it matters a bit, but not much. We bought a long (50 or 100ft, can't remember) pricy cable for my friends parents, and the signal loss was so great that the TV only recognized the signal half the time, but it was all or nothing.

but yeah, 3/6/10 ft isn't gonna make any difference.

There have been some interesting comments here since I posted this article just before I took my son to his soccer tournament. Now that I'm back, I see some commenters have suggested that some of the occupations identified in the submitted article as probably not needing state licenses (as indeed they don't need in many states) do need licenses. Those suggestions by my fellow HN participants are often made on the basis of hypothetical examples or imagined worst cases.

My own sister has formal training in interior design from a baccalaureate program at a state university, and she has pursued that occupation since graduation for more than two decades. I am aware from my sister's work in commercial interior design in a big city with skyscraper office buildings that some interior designers have somewhat of an influence on the safety of public spaces. But it's ludicrous to think that Florida's pattern of regulation of interior designers is in any sense motivated by public safety concerns. If there are such huge public safety concerns from interior designers not being state licensed, why do we not hear news stories from other states with different patterns of regulation about all the people who die from entering buildings that are owned by owners who hired unlicensed interior designers?

The experiment in federalism that has been going on in the United States offers a wonderful comparative laboratory of policies. Unfortunately, for reasons well explored by public choice theory,

http://www.econlib.org/library/Enc/PublicChoice.html

state legislatures often ignore the real-world experience of other states in setting policy, preferring instead to listen to rent-seeking

http://www.econlib.org/library/Enc/RentSeeking.html

lobbyists who divert attention from real-world experience to focus on hypothetical harms that could (maybe) happen if they don't obtain their favorite kind of special treatment. So I would respectfully suggest to my fellow HN participants that if someone wants to make a case that some occupation (e.g., hacking to build web-based SaaS businesses?) should be regulated by state-issued licenses, the persuasive way to make that case is to refer to detailed statistics about actual benefits or harms to the general population, rather than referring to imagination or common fears.

P.S. The one time I had to shop for a surgeon, for my wife, I asked my mom, an operating room nurse who has worked with some world-famous surgeons, to help me find the best doctors in town. That she was readily able to do. People always work the best network they can for the other people they care about most, and life will always be this way, regulation or no regulation. My wife had a completely uneventful and full recovery from her surgery.

One of the goals of a good hash is a uniform distribution. The source files don't have to be random at all. I wouldn't put any money on the odds of by accident hitting a systematic flaw that security researchers haven't yet found in analyzing the hash.

That said, I think it will be possible to deliberately create a collision in SHA256 at some point in the future.
Macros are expending in the typing process. In macro you can use compiler API to type some untyped AST (for example, argument of macro).

For example, "foreach" macro use compiler API to infer type of collection. This macro generate specialized code for different collection kind (array/list/IEnumerable).
