This is why transaction fees will increasingly be important as BTC matures, after all 21 Million are gone the only reward for "mining" will be the award of all transaction fees paid for transactions in that block, so much like the old west, mining is gradually replaced with banking/processing :-)

>When it's found in "soil", it's due to bacteria and small animals (insects, mites) that are in the soil.

I'm not sure what your point is.

>Any B12(-like) substances that are in plants (e.g., spirulina) are unlikely to be in a form that's bioavailable to human beings.

Yes, this is true.

>Vegans have to take B12 supplements of some sort or eat foods that have been fortified with B12. That's just a fact.

Modern vegans do need to take supplements, yes. The question is whether vegans in the ancestral environment would have gotten sufficient B12 from eating unwashed vegetables and roots. As far as I know, research is lacking on that point, but it is plausible.

We've heard this a lot, and I think many of us on the team do still have a soft spot for the current site. It has served us well over time, but it's really time to grow the site along with Python - the language, the community, and everything that goes with it.

One of the biggest parts of this redesign is happening on the back end. One thing I look after on the site is the PSF board resolutions and minutes pages. Oh you see a typo in the latest page? Here's how you fix it:

Get to machine that has the checkout > svn up > edit file > rebuild website locally > run webserver and check local instance > svn ci > wait for server cron job to catch the change and update the live site > confirm on live site

That sucks. For me it's not unworkable because it's not far from what I do as a developer, but it's definitely a hassle more times than not. However, getting less technically savvy contributors is not very easy. We had an administrator who was tasked with updating the pages I look after, and this person didn't know what an SSH key was (not their fault). The whole thing became a non-starter.

The new backend will continue to support the developer-like workflow (which really is good in some cases), and it'll support online editing which will be nice for a lot of things as well.
>It's probably more likely that aliens took his phone, broke it, and placed it back on his counter, than the glass having shattered from thermal shock.

Completely agreed. That's exactly why I said "shattering from thermal shock is absurd, and the glass must be under some kind of stress from how it's secured to the phone" in the parent comment.

To further your explanation a little, the reason the outermost layer is put into compressive stress is that, when it's scratched, the stress will cause the crack to "close up" and so the glass doesn't shatter. Unfortunately, the interior of the glass is under tensile stress as a result, and so if the scratch happens to be deep enough to reach that tensile-stressed layer then the glass will shatter. Putting the glass in a case which alters this carefully managed stress state, i.e. by trying to attach it to a rim that's acting to pull it slightly apart, is what can cause this kind of failure.

But this is all speculation on my part, and even if true the reality might be more subtle.

The article does not explain why Git is that much more efficient. It has some thoughts in the right direction though.

Obviously, SVN and Git have different delta-compression techniques. For a given SRC and DST files, Git's algorithm puts COPY instruction from any position at SRC file. Subversion however restricts COPY instructions to be sequential, i.e. the consumer of generated instruction stream doesn't perform random reads at SRC in order to produce DST.

For the sake of simplicity, let SRC='aabc' and DST='aaxyaa':

Git instruction stream:

COPY 'aa'
INSERT 'xy'
COPY 'aa'

SVN instruction stream:

COPY 'aa'
INSERT 'xyaa'

As result delta-encoded DST file is more compact in Git repository than in Subversion. What are the drawbacks of Git's approach? Good exercise for the reader.

Not with the C++11 by itself but with better compilers we've got since about 2000 (don't forget that the earliest C++ standard is from 1998):

1. Member initialization order being broken in the constructor initialization is a warning pretty much everywhere (except Microsoft compilers, I think).

2. Having a virtual function and no virtual destructor - a warning even in Microsoft compilers.

3. Trivial infinite recursion (i.e. Manager::print() { print(); } is a warning at least in some compilers. I have seen only a handful of projects where such code existed at all so I cannot say how widespread this warning (For me it popped due to problems with scripts generating code, people don't write this stuff ).

This is just from glancing over the article, I am sure if you tried all pitfalls with a modern compiler like clang or even gcc, you'd get a few more warnings.

Though I agree with the main point the author is trying to make - C++ is not just Java with pointers so if you are coming from Java background you should be very careful not to assume the conventions you've got used in Java are the same in C++.

"than the standard 'seeking unix ninja rockstar' stuff"

People do that because they are mimicking seeing others do that and additionally haven't seen it enough (apparently) to realize how annoying and cliche it sounds. If the ads that the wannabees read said something different repeatedly (like "extremely talented c/c++/unix developers" and then listed 20 specifics for example) they might be mimicking that instead.
SpaceX are absolutely right to be using tried-and-tested technology in their rockets, and so Elon Musk's scepticism is sensible in context of what they're trying to achieve. The technology mentioned in this article is more applicable 10, 20 years down the line; the R&D costs would be prohibitive to make it cost-effective to be used by SpaceX now, even if they could get it to work reliably and secure the IP rights.

I've long wondered about this, how long does it take to process a transaction if you add no fee? The fee is pretty significant (especially for microtransactions), and I'm not in a hurry, so I can wait a few minutes/hour.

TL;DR: What's the wait like if you're stingy?
The BBC article, http://www.bbc.co.uk/news/science-environment-20510112 has some nice explanatory graphics.

It appears they are using a liquid nitrogen boiler to chill a helium loop through their heat exchanger and in turn chill the air.

So, perhaps someone better at these calculations can help out, cooling incoming air by 160°C by moving nitrogen from -195°C to -15°C is going to require them to haul up liquid nitrogen and cool a bunch of atmospheric nitrogen that they don't really need. The heat of vaporization is the key that will make their solution win, but by what factor? How many grams of nitrogen must they haul to chill a gram of atmospheric oxygen?
I'm not sure what exactly you mean when you say "debunk what happened to the Hindenburg". The thing became engulfed in flames and crashed. Not much debate on that. Or are you talking about debunking the claim that hydrogen airships are fundamentally unsafe, a claim I didn't actually make? (Incidentally, the fact that other hydrogen airships didn't suffer the same fate doesn't mean they were actually safe. Lots of homes have aluminum wiring but have managed to avoid burning down. You'd still be wise to replace any aluminum wiring you find in your home.)

Obviously a modern hydrogen tunnel would be much different than a zeppelin, and have different challenges. Still, 400 miles of 10-foot diameter tunnel would have plenty of opportunities for problems (whether it's evacuated or filled with hydrogen or something else). I'm not sure an evacuated tunnel is necessarily worse from a safety standpoint, though. It might be harder to engineer, but the failure mode seems safer. A hydrogen tunnel means that a leak will mix hydrogen with an oxidizer. If it's at 0 PSI, this could mean a leak lets oxygen into the tunnel (either due to high-pressure weather or due to hydrogen rising from the leak, leaving a low-pressure environment in the tunnel). If you wanted to fill a tunnel with hydrogen, I think it would be wise to keep at least a small positive pressure to ensure than any leaks are outward only.

I'm totally unclear why methane stored at thousands of PSI is relevant. Is there some 400-mile long, 10-foot diameter, above-ground methane tunnel I'm not aware of?

I'm in a similar situation, although I actually bought a GPS, just 'cause I'd been out of country for so long that the roads had changed.

I've a Blackberry, but with no services active except for voice and text, via AT&T's GoPhone plan - pay $2 on the days you use the phone, and get unlimited text and voice on those days; pay nothing on the days you don't use it.

It's an immense savings, and I'm by no means in a low-wage job or a college student - I just look at it this way: why pay for a plan which would otherwise fund a round-trip for two to Europe, every year?
HN does not support post down-voting. You can however down-vote comments - as long as they are not replies to a comment of your own. Even then, the number of down votes is limited.

With a certain Karma threshold (the value changes over time) you can flag inappropriate posts and comments for moderation and I understand that a certain number of such flags set before a post reaches a minimum up-vote value will cause that post to be deleted.

Personally I see no need for down voting.

Bitcoin is looking increasingly less practical. The size of the block chain is becoming massive. Recently I tried downloading the official client, and after 2.8GB of downloading with the progress bar only about half way through I gave up. If Bitcoin becomes more popular in future the block chain really isn't going to scale well, and that's going to result in a more centralized system in which there are fewer block chain "banks".
Some people also wanted to make sure that their particular transaction was included in this block for posterity. Paying a fee increases the priority (https://en.bitcoin.it/wiki/Vocabulary) of the transaction to make it more likely to be included.

My guess is that they inject liquid hydrogen into the hot air, so the cooling is actually done in free "air" rather than on the surface of a traditional metal heat exchanger - that would explain how they cool it so fast and help explain how they prevent frost in the heat exchanger during the cooling.

This reformulates the problem into "how do we prevent the injectors from..."

a) Melting (liquid hydrogen inside would help a lot).

b) Preventing the liquid hydrogen inside the injectors from boiling and rupturing the piping and injectors.

c) Avoid all the standard hydrogen problems (e.g. embrittlement).

In this guess, (a) and (b) would be a delicate engineering balance to keep the injectors cold enough to retain their strength yet warm enough to not ice up. (c) has known solutions.
In all of the mess about Windows 8/WP8, sometimes you read something that brings reason to a lot of what they're doing. This is one of those moments.

A yearly updated OS that is released simultaneously to desktop and phone is a great proposition. It's basically a more tightly-coupled version of what Apple does, and should pay dividends to people who create apps that span both mobile and desktop.

Of course, it relies on the mobile efforts and Win8 gathering traction. We'll see.

I don't quite agree, although I won't completely disagree yet either. Learning a valuable skill like programming will make you employable and may even have a better ROI than college[1], but going through a "developer crash course"-style program is akin to a trade school or apprenticeship. You might say that going to a trade school to learn to weld is a better investment than college, using the same metric.

College should not be considered a place where you go to get a better job. It used to be that way, but some major problems like grade inflation and the simple fact that a greater percentage of the just-graduated-highschool population is going in to college means that a degree doesn't distinguish you as much as it used to. But there are still major benefits, including lifelong friendships, intellectual stimulation, and learning tertiary skills that are required to be a "well-rounded" person".

[1] Back-of-envelope calculation: $100,000 tuition for an average $1,000,000 increased lifetime earning means that college ROI is about 10x not counting the time-value of money. $10,000 dev school plus personal investment for (let's say) a $40k/yr salary increase over a 25 year career is also $1,000,000, for an ROI of 100x.
