Amtrak has shown no evidence of planning to use batteries similar to what is in the Nissan Leaf or Tesla automobiles for the Richmond-DC or New Haven-Springfield portions of the Northeast Regional runs, instead apparently planning to continue to swap between diesel and electric locomotives at DC and New Haven. There should be plenty of battery powered cars on the road that can cover far longer ranges than DC-Richmond or New Haven-Springfield by the time Amtrak starts taking delivery of these locomotives.
Do you find that most applicants have volunteer experience, is it very common in Canada to volunteer in hospitals? I'm really curious about this, it seems quite strange to me that this should be prevalent and also that you'd find it detrimental particularly (even if they're a bit full of themselves). At the normal Uni entry age most in my country wouldn't have done any volunteering not least in a hospital.

>Why not just call it what it is? It's a strip search.

Personally if they really want to see me naked they can. It's just a hunk of meat. But you're lying, it's not a strip search unless you take off your clothes, ie "strip".

It's a scan of your body. You're perfectly right to object if you don't like it but it's silly to lie about it IMO.
is this true? its not uncommon to see an early 20something drink a decent amount regularly on weekends for years and still end up okay. I find it hard to believe adrafinil could do more damage than that.

As an update: Python 3k solves the namespace issue you mention. (And I hope more and more dev's will finally move on, I love it and only can say it is 100% worth the switch! I'll never again code in pre-3k if not forced to.)

And no, I am not saying that Python outperforms Java, obviously. But it can provide very decent performance at very low LOCs. And then you can identify the bottlenecks and implement that part in C. Overall, a much faster approach than writing in Java (and, obviously, than writing in pure C) with final performance rates beating a JVM easily.

EDIT: No, that is actually even too complicated than what I mostly need to do: For the real bottlenecks I usually just need to find the C library that solves that hard part (e.g., some number-crunching stuff I am doing) and already has a Python wrapper, or you generate one (hello SWIG), or, worst case, you really have to write one (yet have to find that case, although).
"Will make money" is basically what I meant by merit, presuming that the goal of the trade of screenwriting is to produce artifacts (scripts) that serve as force-multipliers for the success of the movies that use them. If scripts are not being selected by their merit, then, it is either because the studios are irrational, or because the screenwriters are using a bad definition of merit, and that in reality it is not that there is a surplus of good content, but rather a surplus of crap no one would pay to see.

"The adult organ has 100 billion liver cells," Baptista says. "The number we seeded is 100 million. We are quite far away from required number. But our aim is to reconstitute only 30% of the full-size adult liver, because that is the bare minimum needed to sustain a person.

So it's not a full human liver but still really cool either way. Although its deceiving when articles compare large numbers like that...would have better to say we only seeded 0.1% of a full liver, we need 30%.

Ask HN: why do you run this Linux distribution?
Howdy fellow Linux fans.

I'll be brief: what is the point of linux distros other than Debian-derived ones, Arch and Gentoo? Those 3 all have very distinct characteristics are are very different from each other, so...

I have a computer I can play with and I was thinking about tinkering with a new Linux distro just for fun. I've used Ubuntu, Gentoo and Arch in the past (settled on Arch and love it), so why would I want to try out SUSE, Fedora or Mandriva? Their descriptions on distrowatch are quite vague.
Companies come and go. If one company that contributes its own patented tech to a project like LLVM gets acquired by a troll, what protection users would have?

I see no reason to trust a company to behave responsibly towards a community if and when it no longer needs it.

Your insistence in stating the obvious - that nothing protects users from third-party patents - while refusing to acknowledge the question of how much BSD-like licenses protect users from patents owned by those who contribute code to BSD-licensed projects is disturbing.
This looks quite suspicious, yes. :)

Very easy to say.

I also like how you attacked with full prejudice anyone who might attempt to contradict you.

You're attacking the wrong people. Did these TSA people in the terminal get up one day and decide that they wanted to do pat-downs on everyone? I'm pretty sure it's been very hard for some of them to stay in their post with the new conditions but they're there because they do have families to feed and rent to pay, etc.. They're people too.

So, yes we do have to talk about the reason that you think you can dismiss people for not simply quitting their jobs because of enforced change that is not their fault and not their choice. We do have to talk about why you feel they should be potentially impoverished.

Why don't you leave your job in protest? That would be as effective as a TSA officer leaving theirs I'm sure.

Yes if all people in your country refused to do security pat-downs then this wouldn't happen. Also no flights would leave the ground (for at least a time).

IMO if you feel so strongly that you're demanding other people leave their jobs then you need to be doing 2 things. You need to be directly supporting those people leaving their jobs financially, and you need to be lobbying hard for a change in the rules/law.

If you're doing both those things then more power to you, TSA people will be happy you're paying their wages whilst they find work.

So, there you have it, in your opinion the "[worst] in the history of all-time worst rationalizations for behavior".

For various reasons I need a throwaway for this but I can confirm I've ordered with United a few times and it has been smooth sailing each time. Their ModAlert is also genuine (compared packaging and job numbers over time and with other vendors) and remarkably cheap. Only prob I had once was they didn't accept my Visa card, but tried again with another and was OK.

It's worth noting that the "retail price" from the original pharmacy is stamped on the packaging. It's in Indian rupees, but it comes out to something like £1.50 per 10.. so they're still making a nice markup.

I know nothing about the entertainment industry, but this idea of 'putting in your dues' by working your way up from a menial position based on personal relationships has always seemed naive.

I get very, very worried when I see "contribute to OSS" as career advice, for exactly this reason. No, we won't pay you, but if you could grind out some boring glue code for the frameworks that our for-profit businesses use to make money, that would be great. Why, if it turns out that you're good at it, we might even look upon that favorably in an interview... some day.

Exactly, basing the assumption that computers are only about data in->do something->data out, is a bit of an old-fashioned way of thinking. These days, the vast majority of computation involves execution loops:

1 - Display something (perhaps put some data out)
2 - Receive input
3 - do something (perhaps combine input with data in)
4 - goto 1

This is true of everything from video games to operating systems.

Dataflow models are simply a subset of the models of computation we deal with these days...they are extraordinarily useful models, but still limited in what they do.
> The problem is that encryption with larger key sizes is computationally much more than 2x expensive. In fact, compute costs are based on a cube of key size, meaning encryption using a 2048 bit private key can be as much as 30x more expensive than 1024 bit.

How'd you get 30? From what you said, it sounds like it should be 2^3 = 8 times as expensive.
I cancelled my satellite service last week. We were paying $100/month for hundreds of channels, and all it amounted to was a backlog of DVR'd Family Guy and Simpson's reruns. I'm much happier so far with Netflix and AppleTV, with the occasional torrent or Blu-ray for the things they don't carry. It takes a lot of AppleTV rentals to match what were spending on satellite.
Perhaps not coffee, but caffeine, the active ingredient, is a "neural enhancer." Wikipedia defines it as a "psychoactive stimulant drug" and says that it "has a generally disinhibitory effect on neural activity." You would have done better to call out the comparison between using drugs and a text editor ;-)
>You've somehow managed to bring two logical fallacies in the same sentence — the straw man and the false dichotomy.

You're misreading.

I presented two possibilities, but nowhere did I claim that they were the only two possibilities -- ergo, no false dichotomy. You aren't clear about where exactly you believe that I presented a straw man, so I can't respond to that one. If you're saying that modern union shops do not result in the sort of inefficiencies I mention above, then the kindest response I can find is that we must have very different experience of union shops. I invite you to examine the union-imposed rules at, e.g., Yale Medical School, which is what I was particularly thinking of when I wrote that.

> The purpose of unions has always been to bargain collectively in situations where individual actions alone would result in a greater detriment to each worker.

Thank you for that basic restatement of the definition of "union." You did, however, leave out the important bit: that the nature of union bargaining is always the workers of a corporation demanding policy changes from the owners of a corporation.[1] These changes always involve a cost which reduces the bottom line profit of the corporation -- e.g. higher pay, shorter hours, etc. From a strictly short-term, monetary POV, anything that reduces the bottom line is non-optimal. In the long term, however, or when other measuring sticks are used (social health, GDP, etc) these changes may be enormously better than the policies they replace, because they result in more total wealth in the hands of the consumer, more leisure time in which to consume / innovate / create / be healthy / etc.

This is exactly what I said in my original post. Hopefully you will more clearly understand the more spelled-out version.

> A corporation is by nature this same mechanism [for using collective action when individual action would be sub-optimal] applied in the market, so which side you prefer — the worker or the owner — is fundamentally one of politics in the end.

While this is technically true (as in, it does not contain an explicit inaccuracy), there are some significant differences between a corporation and a union. Most notably, the benefits of being in a union accrue essentially equally to all members, whereas the benefits of being in a corporation do not -- the owners and top officers reap far more of the rewards than the "bottom rung" employees. Furthermore, their incentive structures are very different -- a tech support guy is paid $N/year as long as he shows up for work and the company doesn't go bust (incentive to keep the status quo), but the CEO is making most of his money off of stock options and/or bonus (incentive to change the status quo).

[1] I'm using the word "corporation" loosely here because it's more commonly applicable and it's easier than naming the various possible employing bodies (government, NGO, non-profit, etc). Most often it's a corporation per se.
HN Version of the comment I posted on your site:

_ _ _ _ _ _ _ _ _

As a teacher in Milwaukee Public Schools, I tend to think that there is a direct correlation between socioeconomic status (SES) and student performance. Students who come from homes where their parents are educated and have jobs and take care of their kids likely are not in the lowest SES categories so they are expected to do well and work hard on school. Kids in this situation generally meet their learning goals.

Kids that have no parental support are common in the lowest SES situations. These kids basically have to raise themselves and their younger siblings because mom or dad aren't there. It takes a lot of training and an amazing school environment to lift kids out of these situations and keep them on pace with their learning.

The big reason why performance based pay for teachers is such a hot issue (besides the fact that teachers WILL cheat on their students tests to get their bonuses) is that every community has such a wide array of challenges to overcome. Kids from one area of Milwaukee have very different environments from the kids across town, for example. It's hard to determine benchmarks for performance when the kids are operating at such different stages of development.
Boston to NYC is about 220 miles. Say a "real" high-speed train averages 180mph then the train trip is 90 minutes. Fewer would make the 4 hour drive. It would also reduce the need for those Nyc/Boston shuttle flights.

Ask HN: Community nurturing
I help run a moderately popular website, Gamers Unite! (http://gamersunite.com), a forum for Facebook social game lovers. It's a slightly controversial site because we also provide tools for gamers to help them advance more quickly which some view as cheating.

We have a member who was helpful in the beginning in the sense that he very vocal in his support and evangelizing of our site and in defending us against "haters" of our site.

However, once he gained status within our site, he started publicizing his own self-serving pyramid-scheme links (not uncommon on Facebook). When we banned his posts containing such links, he started directing his anger at us, to the point of making personal attacks against our admins and spreading untruths.

Nurturing a vibrant community is clearly essential to our success. Any advice? On this specific issue and community nurturing in general?
My initial reaction was that 'millions' must be an exaggeration here. Surely, I thought, there were far fewer than a million cars sold that early. But I would have been wrong: "From 1908 to 1927 Ford produced more than 15 million Model T automobiles." http://www.modelt.ca/faq.html#2

Thanks for the good example!
If the last two digits are divisible by four, the entire number is divisible by four. For instance: 62857724. 24 is divisible by four, so the whole thing is.
Is it fair to sum up the Startup School meeting by saying there's more than one way to surgically remove the epidermis of a feline?
I know:

* 2 - if it ends in 0,2,4,6,8, it's divisible by 2

* 3 - if the sum of the digits is divisible by 3, so is the number

* 4 - Ignore everything but the last 2 digits. If the last 2 digits make a number that's divisible by 4, the whole number is (eg. anything ending in 52 is divisible by 4 because 52 is divisible by 4)

* 5 - If it ends in 0 or 5, it's divisible by 5.

* 6 - do an and of the 2 and 3 tests.

* 8 - Same as the 4 test, only last 3 digits.

* 9 - same as 3, only the digit sum needs to be divisible by 9 instead of 3

* 10 - If it ends in 0, it's divisible by 10.

So I guess the only one I don't know is 11.
For this to be the case you would have to assume that the main reason that a 2,000 year old building is not around is because it fell down due to structural flaws. I think in Rome and Athens there is a lot of evidence that people knocked their houses down to build something fancier, or they were destroyed during war or civil unrest.

So it's not a simple case of survivorship bias, though undoubtedly that is one factor.

Fedora, unlike Ubuntu, has zero proprietary software in its repositories. It, however, has firmware included with it which is why it's not on the FSF's list of approved distros.

Perhaps I misspoke, but I essentially meant it in regards to the way they launch new products. In more ways than not, Google is ultramegacorp. They're buying companies left and right, striking deals with Telecoms and sitting on who-knows-how-many companies' boards.

But, when it comes to launching something new, they definitely have no qualms about throwing the proverbial pasta against the metaphorical wall, and seeing if it sticks, hypothetically.
Do I understand correctly that just physically extracting a certain piece of DNA from a cell ("purifying" it) makes it patentable? That seems silly.
I do math contests competitively, so I remember these things. Here are some rules:

Divisibility by 2: Last digit is divisible by 2 (0, 2, 4, 6, or 8).

Divisibility by 3: Sum of digits is divisible by 3. (You can repeatedly sum the digits until the sum is small enough to manage easily.)

Divisibility by 4: Last two digits are divisible by 4 (00, 04, 08, 12, ...). If you don't know your multiples of four, you can divide the two digits by 2 and then see if it's even.

Divisibility by 5: Last digit is divisible by 5 (0 or 5).

Divisibility by 6: Divisible by 2 and by 3. (Works similarly for all composite numbers, of course. Like 10, 14, 15, etc. Make sure the factors you're checking are relatively prime (share no common factors), or it won't work. For example, divisibility by 2 and 6 does not imply divisibility by 12.)

Divisibility by 8: Last three digits are divisible by 8 (000, 008, 016, ...). Probably faster to divide the last three by 2 at least once then check divisibility by 4.

Divisibility by 9: Sum of digits is divisible by 9. (You can repeatedly sum the digits until the sum is small enough to manage easily.)

Divisibility by 11: Alternating sum of digits is divisible by 11. (Almost always turns out to be -11, 0, or 11. Example: 66374. 6 - 6 + 3 - 7 + 4 = 0, so 66374 is divisible by 11.)
A different perspective - but definitely worth being analyzed. What do you think?
Seconded. I suggest getting on an even keel before making yourself obligated to others. Having a good routine that keeps the level of social interaction normal and healthy is a very very good thing to have before taking on investors' money. The stress only increases :-)
