"One of the new AT&T plans will cost $25 per month and offer two gigabytes of data per month, which AT&T says will be enough for 98 percent of its smart phone customers. Additional gigabytes will cost $10 each."

This is in 2010.

Today that $25 will actually get you HALF the data it did in 2010, five years ago.
All of these are generalizations with a kernel of truth. In real life, I imagine the frequency of occurrence of various hiring techniques falls into something like a normal distribution. Similarly with hiring results.

My thoughts:

1. It's perceived by some to be a maximally objective and efficacious measure of skill and experience. This might be true in principle, but in practice, reading code carefully takes a tremendous amount of time and making judgements about someone's work based on a commit log probably doesn't happen much. My intuition is that this gets more lip service than anything. I imagine employers are looking for lots of green boxes and lots of commits, if anything.

2. All the time. The virtues of open source software often outweigh the perceived loss of revenue and control.

3. The interviewers just don't have the time. They are too busy going to design meetings. Or doing dozens of interviews with a minimum of prep or decision time.

I agree with the statement that startups are like biological organisms evolving in the broth of an economic environment. In @pmarca's words "the market needs to be fulfilled and the market will be fulfilled". Once we move on from this fact (that we can't create startups out of thin air without there being an underlying wave ...without a "why now"), the rest of the actionable advice here will work better for an investor and/or the entrepreneur who views herself more as an investor than say a hacker. Alternative advice is to "live in the future" as PG would say it or to be different as Peter Thiel would imply. What I think this means is to ask yourself how similar what you do for fun/ for projects is to what everyone else is doing[similar --> bad]. How often do you work on that stuff? Do you collaborate with people? I am convinced ideas emerge as a natural consequence of working on ideas at the fringe with interesting people. What is hard is a) working on ideas and b) finding interesting people to work with. Another thing that doesn't help is committing to a company prematurely. Easier said than done, but i think if we as entrepreneurs took it a little less serious...we'd net out with more successful companies.

How come the neutrinos can reach us before the light does? I thought that neutrinos traveled at the speed of light?

Sorry if this is a stupid question.
It's amazing to me how many people miss this point.

I bought a month's worth. I only eat it for dinner around 4 - 5 times a week, meaning it will last me 3 months. My time is worth a lot to me, and I would much rather spend the free time I have after work doing things I love to do than things I don't (which include cooking).

I am a bit of a foodie. I love good good, I love going out to dinner, I love trying new restaurants, and I love eating with friends. Soylent does not affect this in any way, because I don't eat out or eat with friends every night of the week.

Side note: People look at the cost of Soylent and don't factor in the cost of the time it takes to gather ingredients and prepare / clean up meals, which is pretty short sighted in my opinion. This cost is not insignificant.

The No Free Lunch Theorems don't apply in reality anyway, as explained at https://en.wikipedia.org/wiki/No_free_lunch_in_search_and_op...

Essentially: NFL says the performance (1 / number of trials are required to find a solution), when averaged over all fitness functions, will be the same for all optimisation algorithms. However, most fitness functions require more computational power than the Universe to evaluate; making even a single trial impossible to perform.

Since those problems are already impossible, it doesn't matter how many trials our optimisation algorithm would require when tackling them. We can use this unobservable bad performance to offset some observable good performance, to remain within the average dictated by NFL whilst still becoming objectively better.

In fact, one of this paper's authors (Shane Legg) has used this fact to define a general intelligence test which favours performance on simple functions http://arxiv.org/abs/0712.3329
Two things:

It's annoying that they are selling a 2G model. It'll be useless about a year after they start shipping.

The data rates are absolutely comedy. Considering EU roaming laws mandate that carriers have to sell at a wholesale level at 5 eurocents/MB, that is a giant markup. Perhaps there is some level of basic admin on the accounts, payment processing etc, but charging 20x the wholesale regulated cost isn't great.
The Geography of Melancholy
There was another Hacker News thread last month about a 32-floor prefab apartment skyscraper in Brooklyn[1]. Many commenters said the promise was hyped and that construction was slow. It was disappointing because this seems like a good solution for places like the Bay Area where armies of single professionals would happily live in small, private units with common space amenities instead of sharing a $4-5k/mo two-bedroom with a roommate.

Does anyone know whether these apartments would be legal in California? I did a cursory search and it looks like all apartments need one 120sqft room and at least 70sqft for any other living rooms (not storage?). Oakland has some additional requirements about partitions separating kitchens, but it's unspecific about how an "efficiency apartment" designation modifies that. Not sure about SF regulations, assuming they're even more onerous.

Rome's "Authority and command"? We're talking about the late 15th century here. The Western Schism had only ended in 1417. Conciliarism had been strong throughout the 15th century. All the powerful monarchs of Europe were trying to consolidate their power, and wanted, as much as possible, to get money from the Church. The conflict between the papacy and the English king wasn't as harsh as that between the papacy and the French or Spanish king because England was far away from Rome, and the English had been left to do mostly what they wanted.

Spain was ruined by the Hapsburg's wars, in which Catholic France (and its very-Christian king) allied with protestant powers to become the dominant continental power.

We don't use Vagrant for an easy to setup dev environment. It's for two main reasons:
1. Consistent environment across all developers, even in my case which is only 4 devs. One person being a version ahead on node could cause problems.
2. The same environment as production. Getting rid of almost all problems that come from moving from dev to qa/staging due to environment change has been a god send.

Of course it's going to take awhile to setup. It seems like the main argument to push away from it is time spent on setting it up, but this article even says setting up MAMP can be difficult at first. Ever tried to get MAMP to work with non-standard PHP extensions? Good luck. apt-get install php-redis is much simpler.

You do need buy in from the whole team to really get the time out of it, but that seems like a problem with tool consistency across the team - nothing to do with vagrant specifically.

As a user, my impressions is that the latency involved with routing mobile data around is a lot higher (more like a second, even with LTE) than the latency involved with the physical transmission. Mobile data connections are generally more reliable than WiFi, but usually there is a significant lag before results are returned. Is that not correct?

Hey solve, I thought the exact same thing you did! But then -- as someone who recently joined the Google Flights team -- I helped lead some research that included this topic... and was honestly surprised to find that about 40% of the folks searching on Google Flights DON'T pick the cheapest flight.

Price, certainly, is still a huge factor in folks' decision, but convenience plays a very significant role. And, from anecdotal evidence (not part of the same research), brand loyalty is definitely a factor as well (a very price sensitive travel blogger I know still prefers to fly on American, for instance).
I do find it a bit annoying that, on top of the expectation to even have open source work readily available to criticize, there's an expectation that any particular project should act as a de facto resume.
Licensing hardware under the GPL doesn't make any sense. The GPL was written to be applied to software written in compiled languages; it refers to its subject as "the Program", and places requirements on how you may "copy and redistribute" it, or make use of its "source code". It's not clear how this even applies to some types of computer applications (e.g, interpreted scripts), let alone to physical artifacts like a circuit board.

Sometimes you'll see a cluster of links from the same site -- that happens when I find a new RSS feed and backfill some good stuff.

Any suggestions are appreciated.

That's basically MIRI's ethos - basically, once they figure out how to build it safely then everyone will be permitted to go start building it. You can see how ridiculous this is on it's face.
Something related to keep in mind when it comes to p-values is the false discovery rate:

> If you run lots of phase 2 trials with different drug candidates where only a minority (lets say 10%) actually work, then with standard trial statistics (80% power and 5% false positive rate) you will get 4.5% false positive and 8% true positives – so less than 2 out of every 3 positive trial results were real. A much lower success rate than the 5% error rate commonly assumed.

Here are some hard problems to crack then, in particular Value Learning: https://intelligence.org/research-guide/
One thing that took me the longest to figure out was the value of half-assed work. It's actually possible to build things of value with enough half-assed work. I think that's one of the ideas behind the "worse is better" philosophy. Sure, it will take orders of magnitude more man-hours, and sure the end-result won't be nearly as elegant and perhaps not as robust as if something else created by a super talented team. But not everything needs to be created by "rockstars", sometimes you just need stuff that works well enough after a sufficient application of development effort.

I'm not sure I agree. If YouTube is publicly seen to turn a profit, it's more likely to create a feeding frenzy by copyright-owners than it is to pad the bottom line.
> Sodium and chloride levels have been increased slightly, to 1,640 mg and 2,300 mg, respectively. In the past, Soylent has not fully met the Institute of Medicine’s recommended sodium intake levels, due to the challenges of providing recommended daily sodium values without creating an unpleasantly salty flavor.
>
> Thanks to the addition of isomaltulose, Soylent 1.4 can now meet the IOM’s recommended levels for sodium and chloride while maintaining a balanced flavor profile.

I should point out, here, that the IOM's recommendation is controversial, and that many would consider 1.64g sodium per day to still be inadequate. (Luckily, getting sodium elsewhere is easy.)

Where else would it be? We know where the Sun is, with high precision.

Interstellar distances get more and more uncertain the further away things are from the Solar System. Using the Sun as the origin gives a built-in estimate of the error. If we used, say, the center of the galaxy as the origin then the uncertainty in its location would overwhelm any calculations about the distance from the Sun to, say, Barnard's Star.

Lab in Berkeley Accidentally Discovers Solution to Fix Color Blindness
Hey! I'm a New Yorker who has definitely lived in apartments this small. I currently live in a studio that's 325 sq ft.

I also live pretty minimally, so it's actually not that bad. I have room for a bed, a small desk, a small dining table, some chairs, and a TV.

I might be able to fit a small couch in here, but it would be pretty tight at that point.

It's not as bad as you'd think. The biggest drawback is that you basically start using your bed as a couch, which can make things difficult if you're someone who needs really strict sleep hygiene.

If you're someone who collects a lot of stuff, it's definitely not for you. I can move my entire apartment (minus furniture) in 3-4 medium boxes, so it's perfect for me.

It also goes without saying that you don't entertain much at a place like that. You either go out somewhere, or have maybe a couple people over, but any more than 4 people (including yourself) starts to be totally unmanageable.

spinchange, thanks for the love!

Short answer re price discrepancies: it's complicated. It's absolutely in our interest and the airlines' interest to get pricing 100% right, and we do work really hard to eval and improve on this.

One situation that can happen is that an airline has, say, 3 seats remaining at one fare and 1 seat remaining at a cheaper fare; when you selected the flights or immediately before, that 1 seat was still available, but by the time you click through, it's not, so you get the pricing for the fare with 3 seats left.

One of the things that's amazed me in my flights education after joining the team is just how super-dynamic pricing is.

No, to my knowledge it's not based on your referrer or cookies or anything like that ;). I'm just talking -- person-independent -- pricing from hour to hour.

On a related note, I used to think that airline pricing was pretty capricious and random; now I realize that the airlines hire some of the smartest folks to develop pricing strategies, and nothing is left to chance ;).
Protecting Yourself During User Research
Assuming you're on google.com/flights, I'm fairly sure that using a VPN, changing your IP, flushing your cookies... none of that should change the availability and pricing you see on Flights.

And no, don't bother trying to time your bookings. It's kinda like the stock market; trying to beat the market, er, optimize your flights purchase time is likely to lead to sorrow and regret. From the research our Google Flights team did recently, we found that if you wait a week, on average you're gonna pay more for the same flight.

And no, we didn't see any universal discount on Tuesdays, either ;)

That's pretty cool (especially the ending of Tetris!), but the crucial difference is that it's trying to learn by observing what happens during a known-good run, then it sounds like some game-specific learning is performed. In contrast, the Arcade Learning Environment (the benchmark used in TFA) is completely autonomous; there is no human guidance or game-specific learning: anything it learns must work well across all of the games (ie. it's either generally useful, or it gets surrounded by a bunch of conditionals).
