Two Soyuz, actually. They need two because the ISS now has a six person crew and one Soyuz has only space for three people.

Using the Space Shuttle would also not be practical because you can’t swap it out. Those Soyuz don’t stay permanently attached to the ISS, they are swapped out whenever a new Soyuz arrives (every few months). The Soyuz spacecraft is only rated for six months in space (the Space Shuttle is likely rated for much, much less time).

50 years. The wright brothers flew in 1903, by 1953 there had been tens (maybe even hundreds) of thousands of aircraft built, and millions of people had flown on them. Commercial jet aircraft and supersonic military aircraft were being introduced. Air travel was expensive but within the reach of even the middle class with some savings, 20 million people a year were flying.

"Only fifty years", indeed.

Congrats on the success! A simple, elegant app that just gets shit done -- and with a revenue model.

Bit of a blast from the past here, but I want to thank you for some unintentional inspiration you gave me 6 years ago when Steve & I launched reddit. You see, I've always kept a "wall of negative reinforcement" (basically negative commentary that I print out and stick on the wall) that I find quite inspiring.

You deleted the post, but "Y Combinator’s 2005 Summer Founders Program: A Complete Dud" was one of the things that always gave me a boost during some of reddit's darker days.

It may sound ridiculous, but I really do appreciate it. I've been fortunate to have had immensely supportive people in my life - namely my parents - yet I've always relished criticism & negative feedback (maybe it's from growing up with a girl's name?) as motivation to push myself harder to better both my work and myself. Thank you.
> I don't pay more than I legally need to.

Well that's what I meant. You have no particular wish to pay taxes. You wouldn't mind stop paying them. You would mind stop having sex though. I'm talking about motivations that can't be shut off and don't need to be taught to every new kid, because you are born with them. We need to somehow harvest them to make working together attractive.

I would argue that all successful policies somehow come down to the fact that people want them in place. In that regard, taxes are clearly a failed experiment. You cannot force people to do anything (not for long, not forever as we can see from history). The only really effective law, is the one that people love to obey.

Non-blocking sockets and poll are supported in the underlying APR library. There just doesn't seem to be support for the apr_poll stuff in lua-apr yet:

I've been using a similar scheme but without a database. Just a bcrypt hash of my password using the website/systems name as a salt, and then formatted according to an alphanumeric alphabet with symbols.

It also has support for sub passwords (such as "work/twitter") where it simply generates the "work" password and uses that to generate the twitter password. That way I can give the work password to anyone who needs it and they can get into twitter/etc, while not needing to remember it myself.

This is useful because I can upload the password generator to a website, along with keeping copies on my phone and pc.

I'd be interested in knowing the cryptographic security of this scheme, but I'd assume its pretty good.

It almost goes without saying, but one of the biggest benefits in my opinion is that you get to have a different strong password for each set of credentials. Thus, god forbid, if some site you have an account with doesn't encrypt your password in their DB and gets hacked, you don't have to worry about changing all your other logins.
This is right on. Many recent grads have such a strong identity associated with their job that of course it's soul sucking if you don’t like it. But if your life is actually your family, then working a mediocre job to pay the bills and send your kids to baseball practice and live in a safe suburb isn't so bad.
Once you can get on the board and ride, you'll chase the wind for free - trust me :) ... But yeah you can become an instructor or run a kite school, or run Kiteboarding tours or travel around the world in a yacht chasing the trade winds and have people pay a hefty sum for the privilege of staying on your boat (google "best odyssey").

You'll live on the prettiest beaches in the world, meet beautiful women, be in great shape but you won't have money. And from what I've seen, most people who have this lifestyle are VERY happy.

The term 'Cobra effect' stems from an anecdote set at the time of British rule of colonial India. The British government was concerned about the number of venomous cobra snakes. The Government therefore offered a reward for every dead snake. Initially this was a successful strategy as large numbers of snakes were killed for the reward. Eventually however the Indians began to breed cobras for the income.

When this was realized the reward was canceled, but the cobra breeders set the snakes free and the wild cobras consequently multiplied. The apparent solution for the problem made the situation even worse.

A similar incident occurred in Hanoi, under French colonial rule, where a program paying people a bounty for each rat pelt handed in was intended to exterminate rats. Instead, it led to the farming of rats.

If the intention was to decrease the incidents of Cobras/rats causing problems to humans, then isn't Cobra effect a success?
Ask HN: Where did you learn Web Development?
A lot of (young) people ask me where I learned HTML/CSS, and front end web development. I tell them to check out W3schools or tizag.com, but they often ask me if theirs an easier way, and something (not-so-boring).

So I asked myself whats a better spot than HN to ask this question?

Where did you guys learn basic (and moderate) Web Development?
How did you guys practice programming? (Create websites, watch tutorials on Youtube, etc)

It will be interesting to learn from the community itself.

I suppose I should be clear from this point on: I am against Google+ forcing people to show their gender.

"Well... that's the point. I really don't want to talk about it as an ethical decision, and I guess I can avoid that by pointing out that it is more obviously a good business decision."

In this case, I don't like making it a business decision for two reasons:

1) It is all but certain that Google considered the business repercussions of forcing people to show their gender. They almost certainly balanced the number of people they would not be able to get against the fact that the data is not indexed and searchable and concluded that, from a business point of view, it was worthwhile to force people to show gender. In the end, without real data, there is probably not a good way to make the business argument in a way that convinces google that they are wrong from a business point of view. (Of course, while testing, if the data they gather says that this is killing their business, they'll probably change the way it works).

2) If we can make the moral argument, and Google busy it, they are less likely to start changing their default privacy settings, etc... on people just because its good business.

Of course, I realize there is strength in making something a business decision. It means that even if they don't buy the moral argument, we still get the outcome we want. But, in this case, I think the two reasons stated above outweigh this (especially point number 2 given the experience with facebook).

I'm having some trouble connecting your last few paragraphs ("An conception of the idea..." onward), which are very general in nature, to the specific topic here. As far as I can tell, you are basically arguing for some sort of rules based morality. Without getting into if that's desirable or not (though in many cases, I agree it is), its not clear to me what rules you are in favor of. Please do explain...

(On your moral argument and discussion of perceived risk, I essentially agree).

I'm onboard. You know that group that "discovered" that chronic fatigue was caused by retroviruses? And how that discovery was later shown to most likely have been due to contamination of their reagents? That's the sort of shit that you fear when doing research. Although of course you avoid sharing not because of that, but because others didn't share the same superstitions when handling the reagents. :)

I'm interested to hear how much penetration G+ has had amongst everyone's social groups.

Personally I just have one circle right now made up of work friends. They're all pretty technical; about 60% of them were on both my Facebook and Twitter, and the other 40% were just on Facebook. I was looking forward to using a social tool where I could share and hear more from that other 40%, but they haven't been posting much at all. My reasoning is that if they were big sharers they'd probably already be on Twitter.

My friends who aren't in web or game development have shown no interest in G+ though. I feel like the tool's purpose is to connect with people that I know in real life, so I'm less likely to connect with random but interesting people like on Twitter.

As a result of all this I don't get a lot of updates on G+, and those people who are posting seem to be doing it out of hope that it'll encourage use of the service - they're getting more engagement on Twitter.

Early days and all that jazz, I'm just curious to see if it's taken off for anyone yet.

It seems that they have been working on this for a long time, as you can see in this video that they've put up in March:
http://www.youtube.com/watch?v=hPhFc6GqVdU#t=97s

I think it's really interesting to see what huge amounts of time goes into these redesigns at a company like Google. It's very different from what I do.

It's also interesting to see how the design has evolved from what they showed in March to what they finally arrived at.

Consumer prices and manufacturing costs are not necessarily related. Consumer prices include the costs of R&D, marketing, logistics, management, the profit margins and so on. Moreover, saving $0.50 here and there can greatly reduce the costs of manufacturing. Often these little savings can make the difference between making a loss and making a nice profit.
Oh big surprise.
Consider this: probably the majority of "enterprise" developers today are working in Java. And they would rather run their code in a JVM on a PC than on a dedicated JavaStation/SunRay/whatever. That's the kind of entrenchment you would have to overcome.
Not sure that matters too much? I can still identify myself through other means. For example if my online bank password is lost that's an inconvenience. If someone else gets it, that's a nightmare.
As aw3c2 points out, backups and export options can resolve two of the issues you cite.

As for "if your database gets stolen", that is covered by the encryption of the data and the login method: a password that you know (this one you would have to remember, obviously) and a key file (this may or may not (probably not) be counted as two-factor authentication, depending on how you manage the key file). The thief would not be able to open the database to find your credentials.

If the credentials store and the credentials required to access it are both compromised, so someone does have access to all the data stored within, then you have the problem of changing all those credentials before anyone malicious does something with them. With a backup of the database you have a convenient list of everything that needs to be changed so you don't forgot something important (though anyone else with access to the compromised data also has this list...).

While having a central key store creates its own problems if it itself is not secure, I think that little extra risk is small compared to the risk from other password management (using easy-to-remember things that are thus probably easy to guess, and/or even worse: using the same credentials for many uses). The risk of compromised password store is a local issue, so is something you can control (and hopefully mitigate) locally - no one can try brute force my keepass DB remotely unless they somehow get hold of a copy (which is possible I suppose, but not easy and would require them to be specifically looking for my credentials rather than a more general hacking attempt), but they could try brute force any of my many online accounts or just hack a poorly coded online application and read badly protected credentials.

Bad password managers (or good ones badly used) are a problem as you describe, but if used right a good credentials store with unique random long passwords for every service/account is (IMO) better than any other suggested solution I've come across.

I suppose it depends on what it takes for the police to be allowed to forcefully open a safe. If the police obtains a warrant to search your premises, are they already allowed to forcefully open safes? I don't expect so, since they have only established 'probable cause' and are looking for evidence, contraband or what-have-you in general, but are not looking for anything specific of which they can reasonably suspect it is hidden in the safe.

I wouldn't expect the case law to be predicated on the fact that most safes can in fact be opened even if the combination is not supplied, specifically because, as you point out, there are safes that would destroy the evidence in such a case. The justification "meh, who cares if he gives the combination, we'll just open it forcefully and obtain the evidence anyway" doesn't hold for, probably the more important, cases.
They call it a new method, however God created it. Funny isn't it when we discover somtething it is new?

I they think that Web Development is boring, i would say them: "quit, now, and never try again.", Developing, anything, it's not boring, it's thinking, working, studying, you always learn something, you can always make better.

Developing isn't "fun", but it's great to build something on your own and see you product to evolve.

As i said, you never stop learing if you are a hacker and not just a programmer that can only make those couple things he was teached, so there is only one way to learn:

Find something you like,

Check how it's done,

Try do it yourself, try to UNDERSTAND what a code does.(you do not really understand something untill you think it's obvious)

Make it better.

Repeat.

If you are not passionate about what you do you will always find it boring.
I don't know of a book reference, but if you sit down for half an hour and play though the algebra of stddev you can figure it how to combine multiple standard deviations into a single stddev. It's fairly simple and quite satisfying. The sum of squares can be computed by multiplying the mean with the number of elements. So, by storing the number of elements, mean of those elements and the population stddev of those elements, you can take two or more sets of numbers and compute their combined standard deviation as a simple formula based on their stddev, mean and nelems.

There's a wikipedia entry in combining standard deviations (Standard_deviation#Combining_standard_deviations) but it's dense if you don't have a math background (I don't have one). The crux of it is, to compute the stddev of a set you need to compute the average, then sum of squares of the delta [ie sum([elem[i] - avg] for 1 .. i)]. You don't have the individual elements any more so you can't compute the sum of squares of mean_deltas, but using the stored stddevs, means and averages you can recompute that information out when computing the new stddev.

Well, it's a lot of easier to explain with a whiteboard. You're basically subtracting out the information you don't have based on the stddev/mean-aka-avg/nelems data you do have, you're subtracting out infinite series and it all works out perfectly.

numsum1 = SUM(nelems[i] * (stddev[i]^2 + mean[i]^2))

numsum2 = SUM( nelems[i] * mean[i] )^2 / SUM(nelems[i])

combined_stddev = SQRT((numsum1 - numsum2) / SUM(nelems[i]))
