Amazing work! I'll definitely visit more often, these are great.

Minor quibble: the "Binaural Beat Machine" does not produce binaural beats. It plays two notes at the same time, to both ears, which produces an actual beat in each ear (pull off one headphone - you can still hear it). A nice example of how it should sound: http://en.wikipedia.org/wiki/Binaural_beats
When you asked people at Adzerk the questions you mention at the bottom of the paste, what did they say?
I think Perl 5´s syntax got in the road too much for some people.
Personally, I feel like the reason they're not more widely used is familiarly and upfront cost--familiarly being the biggest (seeing you mentioned being scared).

Practice wise, they really seem on par with cartridge, IMHO. I don't feel like I have any fancier technique or am especially careful when using it. I really use it like a would a cartridge. Changing blades means loosening a nut instead of popping off the blade--but I much prefer having 100+ cheap spares so I don't give a second thought to swapping for a sharp blade compared to only having a dozen cartridges onhand (because I lament spending $25) and having to remember to buy more. The only clear downside is flying (in which case, use cartridges when on the road until TSA lightens up).
The Administrative Office of the U.S. Courts has recommended, and many (most? all?) of the federal circuits now have an official policy of, saving web page links to PDF and filing them along with opinions. The Supreme Court tends to do its own thing, but I think that's a simple effective solution.
You say "Lavabit had no such guarantees."

Without me arguing one way or another whether that's true -- do you think if they had better guarantees, that anything would be different here? That the government would say "oh no, we'll back down now"?

Cool idea, suddenly want to buy bitcoins just to participate :)

1,648,531 GH/s is the current target. I can bet below or above that. It maybe sound odd, because I am not really into the Bitcoins, but what (in the very uncertain case) if the target is hit (neither below or above)?
Even if you're really that set on using Microsoft Word, you can use Office Web Apps with Skydrive.

On the Skype front, until WebRTC is mature enough (soon), Microsoft is stuck using browser plugins if they release a Skype Web App. I'd say chances are near zero that they'd have a Chromebook compatible plugin. Complaining that Skype doesn't work on ChromeOS is like complaining that there's no Google Hangouts app for Windows Phone. The market share is too small to be worth the effort, unfortunately.

Now if Google would only open up Hangouts to video bridging solutions like www.bluejeans.com, www.vidyo.com (which.. is the tech powering google hangouts video), etc.
They are only ordering to redirect the domain to a sole ip address? Not serving HTTPS? Should links point to secure versions of seized domains or simply to attest their identity. I think it's ok to say they are the criminals on the internet and not necessarily the other way. Not that requests cannot be legitimate but at least a basic level of quality must go into the actual process because here it just looks awkward. Not to mention shitty html behind it: if you takedown domains, please show some style :)

Very cool visualization, I'd like to see how this sort of technique could be applied to other real world problems.
Also, for anyone reading Shalizi's article, please note that he uses the term "statistical myth" in a non-standard way. By his definition, any aggregate quantity derived from a microstructure model (e.g. temperature, pressure, climate, electric current) is a "statistical myth".

This is not to dispute his calculations or model - they seem solid. I'm just pointing out that his definition is probably not what most people think when they hear the term.
I switched from electric to safety razor and found it easy to use, you can use gel or cream that you already use or try to go fancy with the brushes and poraso in a bowl.

The main thing is that you don't apply pressure you just let the razors weight and sharpness of the blade do the work. Only nicks I have ever gotten is when I messed up my hand placement due to lack of attention when flipping the razor and the corner of the blade got me.

I don't know how long the multiple blade razors take but if I have a weeks growth of hair it takes me 3 times going over to have a smooth shave (once with the grain, once across the grain, and once against the grain) though I usually forgo the against the grain and the shave is pretty good.

Overall time it takes is 10-15 minutes including filling the sink with warm-hot water, lather, shaving, and cleanup.
Heritability is related to the degree to which a trait is genetically determined. The relationship is far from trivial.

Skin color makes this much easier to understand. Imagine a couple, where the man and the woman each have one Scandinavian parent and one Bantu parent. Their children could have almost any skin shade.

If they have identical twins, those twins will have the same shade of skin. Skin color is genetically determined but the heritability varies.

Imagine two people who have the same skin color as our first two, but they come from an island population founded by Norwegians and Nigerians exclusively. They are 20th generation, or 50th. Now, it is likely the skin color of their children will be the same as their own.

Intelligence inherits upon many factors. Even identifying those factors proves to be elusive and hard. The good evidence that intelligence is genetic is twin studies: the good evidence that it is variable in heritability is every family you've ever known.
Boring. The effect size of the variants is too small to find with n=10,000, hence any positive findings are almost certainly false positives which will fail to replicate. That's why the 3 SNPs found recently (http://infoproc.blogspot.com/2013/05/first-gwas-hits-for-cog...) were in a sample of n=101,000.

There's nothing here to undermine the view that genetics causes much of variation in intelligence, it's just that the variation wasn't as clustered on a few genes as people hoped because it would make the research so much easier.
They're very different from typical HTTP requests: very long lived and generally cannot be buffered.
I've spent some time researching shaving and tried out everything from cutthroat razors to electric ones, and my conclusions are these: If you are using cartridge razors, you are being ripped off. Learn to use a double edged razor, shave at a cost of pennies per month (do get the platinum coated blades though), get a better shave and produce so much less waste.

Pro tip: For most skin types, bar soap works equally well or better than any shaving cream/butter. For the rest, shaving oil will do the trick.
Looks interesting! Waiting for the weekend to try this! :)
I ran into something similar interviewing at an NYC lab; loved the culture, loved the pre-screening interview, team was great, did well at the interview, didn't get the offer. I couldn't be happier at my current job, however.

Just have to roll with the punches! It's a little Bioshock-y, but I'm a firm believer that regardless of where you are, things will end up pretty similarly.

P < 0.05 means that the probability of seeing the observed results if there is no difference is less than 1 in 20. So, if you run the experiment 20 times, you'd expect to see a link once, even if there is really no link.
It seems silly to me that people spend money on spurious insurance. You're effectively betting in a Casino (you're not the house). Unless you think you have some sort of edge on their team of actuarials, or you think you're an outlier (w/ exceptionally bad circumstances), you're better off keeping the premium (along with its expected profit).

I suppose if you want to be super technical, you should weigh the risk/reward factor of the profit margin in the costs and the value that would be paid out. I'd argue few of us are capable of doing that math well, nor would it be profitable to spend our time doing it (because we have a business to run/build)

In my case, the only insurance I carry is that which is required by law, or offered for "free" (eg, employer paid insurances). I'd still prefer to have my money. I'm betting that Im quite normal.

Electric shavers are awful for getting any sort of reasonable shave, which is probably why they aren't used much.
Not necessarily. We had access to the entire group and whilst this particular candidate was clearly the strongest, the average level of talent and potential was exceptionally high.
This really isn't true on a wide scale. There are exceptions but most hunter-gathers tend to be very egalitarian. There were no permanent leaders, and everyone worked together as a team.

I'm not being sarcastic, but I wonder what the intersection of the sets of people who leave smoke detectors disabled for convenience and people who are willing to pay $120 for a smoke detector looks like.

As an aside, I genuinely have no idea what the fuss is about. In my entire life, I have never been bothered by a low battery smoke detector alert. I take 5 minutes and change the batteries in my detectors twice a year and they never ever beep.
I was shocked when I saw the ad free version priced at $49.99 for new subscribers!

The point isn't that it would be hard to shut down a particular node. The point is that it would be hard to retrieve evidence from one.

Also, "easy to shut this down by triangulating the source of these transmissions" -- currently this isn't so easy for domestic US law enforcement. The government could equip law enforcement to do so, but at significant expense. Also, keep in mind that "these transmissions" are just regular broadband and wifi signals.

EDIT: It would be easy for telcos to figure out where the mobile broadband nodes are. What if you put them on trucks, and only had them in an "active" state capable of decrypting their own hard drives while they are mobile?

Haha, given the daily hash rate volatility can be +/- 300,000 GH/s, there is a 1/300,000 chance that'll happen.

This is an interesting demonstration of the dangers of mutability in the presence of shared state.
Not to be at all dismissive of the findings and their significance, but this was a study funded and interpreted by a company that sells posture support products. Not done in conjunction with an academic research lab, but done on a company generated survey with no public access to the results. Call me a skeptic - not of the findings, but of the research methodology.
Frankly, they're not mediocre. I've been a DSC subscriber for about 8 months, and they sell nice products. I can't use a Safety razor, my skin's too sensitive and I break out, so the multi-bladed comfort razors work well for me and theirs are just as good as anyone else's at a lower price.
Agreed, but it's in the statutes, so the board has to abide by them (or risk liability). It's also non-trivial to change the statutes of a foundation ("stiftelse") in Sweden.
It was frowned upon because what Enron was doing was both illegal and immoral. What Lavabit was doing was neither. Further, Lavbit's founder took a stand on a believe in the right to anonymous communication. Compare this to Enron, where destruction of evidence was purely in an effort to hide evidence of culpability by those who ordered the destruction.
Yeah, the few times I used one, I still had a 5 o'clock shadow.
Often placing it sufficiently far away from the kitchen isn't possible. I have a fairly large—by NYC standards—apartment. Our smoke alarm is around 3 corners and 20 feet down the hallway, but it goes off LIKE CRAZY. Basically if the stove gets hot, it's going to go off. We have 11' ceilings, and nothing I can stand on in the apartment is tall enough for me to reach it. After waving towels at it and poking at the silence button with a broom handle ad nauseam, I borrowed a ladder and took it down before cooking a big dinner for guests. I know I should reinstall it, but the silence has been fantastic.

So yes, I think the Nest smoke alarm does have a major upside: people in my situation would actually use it.
Nice that it has an IPS panel!

I bought an 11" ThinkPad X131 but quickly returned it because the viewing angles were woeful. The hallmark of a garbage spec panel is noticeable vertical shift even when looking at it dead on.
Very cool! I'm curious what tech/lib/api/sdk you're using to automate sending payments (ie. in the case you stated of someone betting over 1btc)?
Good point in the article about how people should not start a startup by saying they are going into startups. Many of my friends (including myself) made this mistake :P Problem, Solution, and then the rest ...
Suppose that Lavabit sold smart cards for end-to-end encryption, and as a service would store ciphertexts for you. The government shows up with a warrant, Lavabit says, "Sorry, we cannot comply because we cannot access secret keys or decrypt messages by some other means." What exactly does the government do after that?

The point is that Lavabit's architecture did not resist these kinds of demands at all. At best all Lavabit could do is protect your mail until you log in.

Not really, since it relies on Emacs' docview mode, which can display the pages of a pdf file; I'm not aware of a way of doing that with vim. If I were doing it in the terminal, I'd probably use w3m in Emacs to roughly render the HTML. I don't know if that's possible in vim either, but it seems more likely.

You could give Pixtulate a try (http://www.pixtulate.com). Detecting the client's properties (pixel density, screen size, etc) would still have to be done via JavaScript on the client, but then just append those properties as query parameters on the img's src attribute and the image will get converted on the fly to whatever your visitor needs. Not only do you not have to pre crop or scale your images, every image is specifically tailored to your visitor...not just a simple 1x vs 2x.

Ambulance sirens don't rarely have false positives, because there's a human operating them. If ambulances frequently drove around with their sirens on while not actually in a hurry, people would find it obnoxious, and they would quickly learn to not actually trust the sirens as a signal of a real emergency.

The appeal is price. Gillette blades are dramatically overpriced, even in bulk, which is what created the opportunity.

Of course, DSC is overpriced compared to Dorco, for exactly the same product.
There are a whole lot of product types where an adequate one from Walmart costs $20, but plenty of people spend $100+ on better ones. For instance, anything you can put in a kitchen. Not sure why so many objections to this product even existing.
The problem is the decision to do this is never in the hands of the wage-earners...

Read the instructions on your CO or smoke alarm about where to place it. It's true that most CO detectors are designed to be placed on walls, but combo detectors are often built to be placed like smoke detectors, on or near the ceiling. You want to prevent both false negatives and false positives.
IQ becomes more heritable the more homogeneous an education and development a group has. So it is probably less heritable in a very poor country where there is a large disparity in the kind of nutrition and education someone has access to (lots of very rich and very poor people).

> Making obnoxious sounds is a feature not a bug.

Making them only once every thirty minutes is a bug not a feature.

I was awakened in the middle of the night by one of my smoke detectors beeping once because its batteries were low. But it stopped beeping, and did not flash or give any other noticeable indication that its batteries were low. There was no way to determine which smoke detector it was. (Or at least, none that I could figure out at 2:00 am.)

Any possible action was useless (I had no batteries handy), so I went to bed.

Thirty minutes later, same thing again. Awakened, couldn't tell by which smoke detector. I could think of nothing to do other than to remove all the batteries in all of my smoke detectors.

Bad UI.

Actually, we're using Network Hash Rate rather than difficulty. Difficulty changes every ~2 weeks.

This is the API endpoint we're polling is https://blockchain.info/q/hashrate

Hash Rate is an inferred number though. See http://bitcoin.stackexchange.com/questions/11139/how-is-the-...
The competition factor is also very important: if the world population (and entrepreneurs) growth by 400% it is possible that the "same" few companies will reach the billion (adjusted by inflation)
However, it's quite easy for us to believe our aptitude will make us the exception. Adding a numerical grain of salt is helpful for the evaluation.
"Silicon Valley Syndrome". Yeah because only people in Silicon Valley suffer from sitting too much...
Being legally bound to give up the information is equivalent to being forced. If it wasn't forcible, why did Lavabit have to choose between compliance and shutting down?

Could you clarify what you mean by "How was it a handwave if it actually worked?" Lavabit, like Hushmail, has had no problem giving up information to law enforcement in the past.

sort of.

if i have 10 coins, 9 of which have 44.4% chance of heads and 1 has 100% chance, choosing a coin at random and flipping it has 50% chance of heads overall. sure, there is one outstanding coin.

the "fallacy" is true when you look at the whole rather than the individual factors, which include aptitude in some cases so i guess you're correct on the last point.

Samsung phones and tablets face US import ban
I imagine that many people on HN would wither in a six-figure corporate job, and virtually all are aware of the rarity of the $1B exit. I'd take a self-sustaining entrepreneurial situation over the day-to-day corporate grind any time. You're still a rare hero if your exit is $100M or "only" $10M. Even a $1M payout would put you ahead about twenty years compared to that corporate job, provided you don't live like it's your new salary.
Stream of blades? Maybe if you work at a barbershop. Even if you only get one shave out of a blade (I think most guys will get 3-5), a hundred pack is tiny and will last 1/3 year. For most people, that's at least a year supply.

Unlike shampoo and other bulky disposable products, razors are quite tiny.
If you want to step it up a notch, get Feather blades (if they work for your skin). I've tried half dozen blades, and stuck with Feathers for their sharpness. They are considerably pricier, though still cheap in comparison to any regular cartridge, and they last a few shaves without dulling. I've purchased 50 over 2 years ago, and I'm finally on my last 5-pack. This time I'll be buying 100 for about $25.
Not to sound too snarky, but I would look at your cooking technique. Also, as others have mentioned, a better smoke alarm may also alleviate the problem.

A Little Graph Theory for the Busy Developer
I use a standing desk for 100% of my workday, but I'm getting really tired of the "humans weren't meant to sit" line. Humans weren't really meant to do anything, we evolved over time to adapt to situations as they happened. We can stand, we can sit, we can run. The only problem is that specializing in one area for 8 hours a day means neglecting the other areas, and that's where the problems come in. The key is not to say "humans weren't meant to sit", but "humans lose muscle tone and flexibility if they only sit" or something more quantifiable.
