>Studies like this make you question how much of our folk knowledge and wisdom is false

If you really start to try making hypotheses and then test them objectively, and keep an eye on your track record, it starts to become surprising that folk wisdom ever turns out to be true. A maddeningly small minority of plausible hypotheses are actually true, and confirmation bias is strong. If you haven't already, you should probably just go ahead and cut your confidence about everything you think you know in half - especially if it isn't backed by hard science.
Quora: Is it possible to buy a country?
I was with him until he said that. Is an excuse to give up on anything. You might as well believe in destiny and that your entire future has already been written. Who believes something like that? Seriously. Does he believe that that girl woke up one day and started drawing like that? He is wrong on this count. What you need is perseverance.
Did they floss?
CEO...sure, but how about a founder? Entrepreneur? CEO who is the original founder? I could guarantee the figures are far different.
No native browser offers anything resembling a matrix API (or even a complete mathematics api; JS's Math api is pretty minimalistic). People implement it themselves, using libraries like glmatrix.
Ask HN: Questions about your career.
I have some questions for those of you working or interning. I'm an undergrad CS major about to graduate and I'm asking these as part of a business communication course at my university. I am particularly interested in hearing from those of you who are starting your own company or are involved in recent startups. Thanks in advance; I look forward to learning more about y'all.

Tell me about the company you work for.

What is your role at this company?

What do you like most about your current job?

What do you like least about your current job?

What advice would you give to a CS student graduating next month?

What have been some of the biggest roadblocks in your career?

How do you recommend finding mentors and networking with fellow computer scientists and entrepreneurs?

Tell me about your favorite project you have worked on or contributed to.

Who within our industry serves as a role model to you?

What is your primary goal you have set for yourself professionally?
How did you find your sales agent?
You're missing my point. The Culture and the Azadians were very anatomically similar. That's silly and lacks imagination.
Well... has flossing been shown to be useful for human health?

ETA: quick Google, found one meta-study. Results:

"Trials were of poor quality and conclusions must be viewed as unreliable. The review showed that people who brush and floss regularly have less gum bleeding compared to toothbrushing alone. There was weak, very unreliable evidence of a possible small reduction in plaque. There was no information on other measurements such as tooth decay because the trials were not long enough and detecting early stage decay between teeth is difficult."

http://summaries.cochrane.org/CD008829/flossing-to-reduce-gu...

So, pretty weak evidence, though perhaps mostly from lack of trying. It can't be considered as important as brushing.

Then again, how do we know brushing is important? Time to find some other studies...
It may be interesting to note that I didn’t stumble on this from a compsci perspective. Rather, I was wondering to myself, what could source control do if it understood the code it was managing?
The artist he linked to is exactly the kind of art that one can get better at with practice and a good teacher and curriculum, and does not require much in the way of mystical innate talent.
There is some information I did not know about there. However, regarding this:

> It is also not the case that only one person has been prosecuted over cartoons but no real child pornography; there have been at least two notable cases so far (and likely others that have not made the news):

The Hadley case is the one that I was referring to where he plead guilty. In the Whorley case, he was in fact found to have "14 digital photographs depicting minors engaging in sexually explicit conduct" (http://caselaw.findlaw.com/us-4th-circuit/1431669.html)

As for there being other cases that haven't made the news, I doubt it. This is something that free speech advocates are paying close attention to, after all.

In any case, I agree with the rest of your point.
Yes. Apple doesn't let you do the parts that make a browser tick.
You'll end up with every loadbalancer needing a near-instantaneous perception of every server's queue

But that's not true. Only the loadbalancers concerned with a given application need to share that state amongst one another. And the number of loadbalancers per application is usually very small. I.e. the number is <1 for >99% of sites and you need quite a popular site to push it into the double digits (a single haproxy instance can sustain >5k connect/sec).

Assigning pooled loadbalancers to apps while ensuring HA is not trivial, but it's also not rocket science. I'm a little surprised by the heroku response here, hence my question which constraint I might have missed.

My understanding is that Apache Zookeeper is designed for slowly-changing data.

Dyno-presence per application is very slowly-changing data by zookeeper standards.
Try charging by value?
It's scary because, knowing only one language means that he can only think about, and express solutions to, any problems in terms of that language. In this case, he was not expert at Perl either, so the net result was ... not good. I remember seeing Perl programs that would have been better written as very short shell scripts.

Note that "mainly just knows Perl" is quite different from "only knows Perl".

Since then, I have never met another programmer who knows only one language; I think they are pretty rare. As for proving the case, I don't think I can: there may well exist a good monolingual programmer out there. It's just not likely.
And disables the generation of type checks and bailouts in the output, yes?
I'm a long time reef keeper so I instantly jumped on this with the kickstarter campaign. Like many that bought this tank they were littered with issues and flaws in the design that sent the jellyfish to their death.

I consider my reefing keeping ability as advanced with a 220 gallon main display. This tank was also advertised for beginners. As someone who understands the ecosystem, how to mix the salt/water and test for common parameters I would highly discourage this tank and jellies to beginners.

This tank had too many issues.

There are competitors:

They may cost more but the reviews are much better.
Flossing supposedly helps fight gum disease, halitosis (by removing some of the gunk stuck between the teeth that toothbrushes can't get at) and other mouth afflictions.

How much of that "research" and "science" is actually funded by Colgate, Johnson and Johnson and the like I don't know though...
People create throwaway accounts all the time. Allow people a limited number of posts per day to anonymize their screen name. I think you'll get much more candor on some topics. And with this you can better sort comments and stories since HN will still have access to karma and other signals. And perhaps on an anon post, we could see an anonymized version of their karma (what range their karma is in, say 0-49, 50-399, 400-999, 1000+). This might allow us to take someone's anon comment more seriously.
"You're better off setting yourself on fire -"

That plainly isn't true. Why come to HN to make hyperbolic generalisations about cancer therapy? There are many people with advanced widespread disease who choose to have treatment. Are you suggesting that they are all foolish or coerced by doctors? Really? Would you be happy to come down to my cancer hospital and tell the 33 year old woman with 2 young children that she is better off "setting herself on fire" than having chemotherapy?

Your last statement also is incorrect. I spend just as much time talking about stopping therapy and options that don't involve chemotherapy as I do about giving chemotherapy.

Webkit was the only thing the mobile web had that apps did not: a mostly un-fragmented codebase. Now developers will have to test their mobile web-apps against even more browsers reducing time-to-market efficiency. Hopefully competition will lead to faster improvements by top players (Google), but the more likely scenario is the least incentivized player (Apple) will drag their feet re-creating an IE6 scenario where one browser will slow mass adaption of standards.
I heard once that Airbnb thought the "breakfast" in Airbed and Breakfast was a crucial element of the experience for the first year or so. It took them awhile to realize no one cared about the breakfast.

Perhaps the Jellyfish aren't the crucial piece of the experience for Jellyfish Art? With your anecdote plus the story about the restaurant keeping the tank and using it for fish, perhaps there's something there.
> But even more interesting, they also reported that they felt less stable and more unbalanced after the stretching than when they didn’t stretch.

I find it somewhat suspect that the study doesn't say they in any way tested the athletes stability or balance, just that they took them at their word. It sounds suspiciously like it might even be the Dunning-Kruger effect in action.

Another thing which is suspect is that these studies are done on very short time-frames. It's quite common that things that are beneficial in the long-term result in short term problems. I'd be very interested to see some multi-month or even multi-year studies, especially studies working with more dynamic metrics (for example, taking populations of sports teams and comparing win/loss numbers.)

In general I think stretching is important in a variety of ways for physical activity, and these studies are all focusing in on some very narrow artificial activities I don't personally do very often. I guess this validates that I don't stretch before getting on my bicycle, but it doesn't really speak to stretching before dancing or anything other than strength tests that hit very specific muscles for a short period.
As part of feeding the type info, it is clear that various type checks are not needed, yes.
I can't help myself. You were literally shocked?
The problem is one of cost benefit: the costs are high in terms of tooling while the benefits do not seem to be big enough. Intentional Software was a whole company founded on this idea and it hasn't really gone anywhere.

There is a small trend back toward looking at structured editors; in that case you have no choice but to serialize a tree.
Can't speak for the rest of the world, but at least 99% of India doesn't floss. Just sayin' :-)
The point is that you are overstating the security benefit of your solution. A breach of the server will now only compromise wallets of anyone who logs in until the breach is detected instead of all wallets instantly.

Definitely feel the same as you, but I feel I'm more healthy now than at a 9-5 salaried job. I can get go for run anytime I feel like it, 2pm run for 2 hours? Why not?

The downsides are definitely there though. Trying now to build a product that generates passive income to stay sane during the times in between contracts.
Can I ask your age and what you studied java or c++? thanks.
Running faster may use more power but it generally uses less energy which is the constraint in a battery-powered device.
I know an entrepreneur that bought a well known franchise. He told me he worked without a day off for the first year before finally taking a Sunday off. My gut was to call bullshit. Employees around from that time confirm. He's very successful today.

That's gotta fuck up the average.
When you don't pay for it, Spotify interrupts your music with shitty commercials for country music, while Rdio just cuts you off after awhile. Hence, Rdio was the one I ended up using long enough to decide to subscribe.
I didn't really feel like I could chime in to this thread at first, because I don't play the latest COD or Bioshock, or whatever the latest gen games are.

Then I saw your comment.

The most fun I've had with a video game in a long time was Braid. A novel concept of the old side-scroller. I'd throw my wallet at the screen for a new Braid with even a few new time-altering features. It was relaxing and fun.

That isn't quite the "1 programmer, 1 artist, 1 sound engineer," you mentioned, but glancing at Wikipedia, it was close to that.
The advantage to FPGAs is that they can be designed rapidly. ASICs are cheaper to manufacture and usually run faster.
I'd rather be cut off honestly than hectored into subscribing by having my music continuously interrupted with advertising.
You didn't have context. It's not an article, it's notes for a talk I gave. The audience were a bunch of Las Vegas hacker kids and entrepreneur types, who tend to be forty drinkers anyway. It was shorthand for "sit and chill outside". Which I think they understood.

On the other hand, I've spent a lot of time being poor and being around poor people -- in the ghetto, in rural trailer parks, etc -- and actually, in my extensive experience, poor people do tend to be heavy drinkers. Are you seriously suggesting that sitting around in the hood getting your beer on isn't a staple of working class life? If so, we've been experiencing completely different parts of America.
I pulled my old joystick out I'd kept for the last ten years, only to realise my PC doesn't have a serial port. Warning!

(I've no idea how long I haven't had a serial port. Which makes it worse.)
I think geo-tarded is OK; something retarded is delayed. Geo-limited is probably more realistic in many cases though.
Nope. If Google wanted to push things through it would certainly be possible as the single largest contributor, but that's not a productive way for anyone to participate. Instead, it's just a matter of simple project divergence. Apple landed the WebKit2 layer a few years ago, which was largely incompatible with the Chrome architecture that predated it by several years. Some minor efforts were made to unify parts, but WebKit2 continued to move in a direction that was increasingly incompatible with the existing Chrome architecture. Rather than burden everyone by continuing to maintain a codebase between these increasingly divergent approaches, it made sense to split.
Ask HN: What does a job-seeking start-up developer use for a "resume" today?
I've always spent immense amounts of time on my resume, perfecting every line and making it look nice and crisp on one page. But I've always had my resume geared towards big business and government, since that's where I've generally worked. All of my programming work has been for myself or freelance, where I could simply show a project portfolio and didn't need to have a formal resume on hand.

Thinking about getting a job at a start-up instead of continuing work on my own, I realized that I don't know what passes for a resume these days in start-up-land. Is a formal, crisp one-pager still required? Is it Linkedin? Do I simply send over my Github profile? Is it basically a requirement to keep a blog now and self-promote?

The question arises from the fact that all of my programming expertise was outside the context of a formal job, so my one-page resume doesn't tell the "developer" story you'd expect. On the otherhand, my Github isn't standalone, since most of the work I've done as been closed-source for clients.

What do you think? Could you provide examples of what you've seen or what you give out? Do you even use a resume?

Rails. Enough said :) You won't get it till you use it.
Many exercises are simply not safe if your muscles are tight or you lack the flexibility to do them properly. Swimming, weight lifting, most sports come immediately to mind.

What about stretching in between?

Like you, I abandoned pre-workout and post workout stretching without any ill effect.

I often stretch in between though, and have found it can be effective in relieving chronically tight muscles. For example, I had a 'permanently' tight hamstring that I fixed with 30 seconds of targeted stretching per day for about a month.

I use it for either imbalances, or for soreness from weight-lifting. However, I'm less certain of the usefulness of what I'm doing compared to my hamstring fix.

Those stretches were provided by a physiotherapist, and worked very well. My previous hamstring stretches had achieved nothing. The ones he gave me were generally dynamic stretches.
I suspect our diet has changed considerably since our ancestors' time. So all the extra sugars and processed food we shovel in our mouths is bound to affect our oral health in ways that might necessitate additional cleaning measures (e.g. flossing).
It has almost nothing to do with the domestic IT product market and everything to do with demand. Australia has a very high demand for talented programmers at all levels. It really surprised me when I came back just how many companies are using node.js or Ruby on Rails. The steam games, etc, has more to do with regional pricing. So many products are more expensive in Australia for almost no reason other than that people will still pay for it.
FPGAs are the same speed as GPUs but cost more, so they're only better if you're paying a lot for power.
Haha that's neat!
Meh. Diving a little bit more into the results on how well the hash kernels algorithm did with UCI Adult Names data set is mildly disappointing. Take a look at the results (http://archive.ics.uci.edu/ml/machine-learning-databases/adu...) and you'll see that hash kernels rank 14 of 17.

To be fair, I would definitely like to see how this algorithm does with other data sets as well.

All I see this algorithm doing is basically a projection of a highly dimension feature set onto a random n-d projection via a hashing function. Another words, it's not clear to me how an optimal classification boundary can be constructed using this random projection. I feel comfortable with understanding the performance characteristics of techniques such as SVM or vector quantization since they both focus on implementing algorithms that optimally reduce the dimensionality of the feature space. However, random projects are, in my humble opinion, overrated.

Also, there are two additional sources of parameterization that might make it difficult to use this tool: the selection of a hash function (and accounting for the information loss via a random projection) along with the arbitrary hash kernel array size. That makes it somewhat difficult to train and validate a model.

However! I really do like the ideas presented here and look forward into diving into this and other variants. I really appreciate the OP for taking the time to piece together this cool tool and compare it's performance with other algorithms.

If you are responsible for the security of any kind of system and have not read this book you may want to fix that asap.
Like a couple people have said, this is nothing new--it's an affirmation at most. But what also is missing is that it is completely reliant on the individual. Warmups are RELATIVE to YOU, the athlete.

I played 3 varsity sports--soccer, swimming, and track--throughout my 4 years of high school but made sure that I did a dynamic stretch of MY OWN before getting into any stretching/exercise with the rest of my team. I stayed healthy throughout high school. When I got to college, I decided to play ultimate frisbee and made the A team. I became lazy and started stretching with the team--the coach had us do a relatively rigorous dynamic stretch. I wasn't a fan but went along with it (again, I was lazy). About 5 weeks in, I pulled my hamstring badly and it took me about 6-8 weeks to fully recover. I don't want to jump to the conclusion that not doing an individual dynamic stretch was THE reason for my injury, but it definitely was a large contributing factor. From the time I came back until now, I make sure to do my own dynamic stretch before getting into any exercise, light or intense--it works.

WHY?

The whole point of stretching is really to get your muscles moving and to be comfortable. Only I can decide when I feel I am ready to go...and only you can decide when you are. So do what you feel is best for you first, then immerse yourself in activities that your peers or team is doing. And I promise, this will not be held against you as doing something that the team is not. Hell, I was the captain of my swimming and soccer teams for my junior and senior years. If you're helping yourself, you're ultimately helping the team--especially in this context.

Top 20 Tech Venture Capital Firms of 2012
In the case of Venus, the Soviets had sent several probes (Venera) from the 60s into the mid-80s. When the first probes were sent to land on the surface, it was discovered that the atmospheric pressure induced (about 100x the pressure here on Earth at sea level) was crushing the probes before they even touched down.

It took until 1970 for the Soviets to succeed and the landing device lasted a grand total of a half hour once it had landed on the surface. In fact, it barely survived due to the fact that the parachute broke and it ended up hitting the surface at 60 KM/h. It registered CO2 levels of 97% during its descent.

Venera 9 was similar in concept to the Viking landers and landed five years later, but it managed to last for almost an hour before failing due to the immense heat. The longest any Venusian surface programme by the Soviets was just shy of two hours.

Let's compare this to the Americans' probes to Mars: all of them have managed to out-last their stated mission. We have a rover that was intended to do its job within a 90-day period which instead has defied its masters and instead continued on to this very day.

The reason why I completely discount Venus as a place we'll ever visit or colonise for that matter is because it comes down the old principle that I like to follow: it's easier to bundle up than to bundle down. I can put on layers to keep my body heat in, but I cannot do much without expending energy to cool myself down.

Venus is not a backup.
