It's impressive to see how many of the complaints have been addressed by C++11, actually, and how many others have been addressed by compatible changes to the compilers and standard libraries (in particular, template related error mess

The distinction is meaningless. It is always the case that the currently economically active part of the population pays for those who aren't active. [1] If you prefer thinking in monetary terms (as most people do), think about somebod

The Apollo project is historical precedent that shows that precisely this type of project can go much faster, given the required budget and focus. The second part here is also important, of course. Just pouring more money onto a problem isn

I guess the libc that comes with Ubuntu doesn't count as a good implementation.

Wow, thanks for pointing this out. I just tried it out for myself, and indeed "rep movsb" is consistently (and sometimes significantly) faster than the standard C memcpy for aligned copies larger than 16KB or so on my Intel Core i

The fact that modifying the observed public key doesn't change timing is not surprising: If the CPU is intended to verify the integrity of the microcode update using public-key cryptography, then the public key used to verify the signa

I guess somebody downvoted you for the shortness of your comment. You probably know this, but repne movsb is actually a fairly slow approach to copying data compared to the various SSE assembly implementations that libc and friends have. Th

It is misleading to claim that this does nothing for the lows, because everything that's happening here is symmetric. Let's say that aluminium production currently draws a permanent base load of 1GW. Let's say that the minimu

The interesting thing about the table shown in the article is that even while the author laments it, it actually illustrates a good development: the table has an "hourglass" structure. There is a stable part (fundamental technol

People legitimately object to accepting a patch that fixes one issue but can lead to other problems down the line. IMHO, even not accepting the patch, but with suggestions for additional improvements would have been better behaviour. As i

Interesting, thanks for sharing that graph. The thing is, though: the Japanese government isn't trying to debase the Yen because of their high debt . The reason they're trying to debase the Yen is to encourage growth via exports

While I appreciate your comment, why don't we think outside the box a bit? Isn't it good when people save a lot of money? As long as the savings are fairly well distributed, this means people become more economically independent

Yes. This whole "deflation makes customers delay their purchases" thing is annoying precisely because there really are much better reasons for worrying about deflation, and serious economists are warning against deflation all the

Your response completely misses quanticle's point. Quanticle was talking about the choice between inflation and default . (So, when it comes to your life-savings, both can be utterly destructive.) Instead of actually addressing quanti

Japanese government creditors as a whole will never want to get rid of Japanese bonds in the kind of mass-selloff that you're implying unless the Japanese government does tell its bondholders that they're not going to be repai

To be fair, "real GDP" has a somewhat precise economic meaning as measuring GDP while taking inflation into account; i.e., take nominal GDP and divide it by some measure of inflation (it is only somewhat precise because one can qu

I would replace recommendation #5 with: use a different key on each physical machine. My home desktop has a different private key than my private laptop, and at work I have yet another SSH private key. This makes more sense to me than separ

Git is one of those things where it pays off immensely to understand the underlying object model. Learn about commit objects, tree objects, and file blobs. Then learn about the staging area. There are some things layered on top of or next t

Realistically speaking, I suspect that if this does take off (and it is a very cool idea), they won't actually install those things in living rooms due to noise concerns. Those racks are going to be in the basement where the other heat

The important part is that the anonymity set - the amount of traffic among which those with a need for anonymity can hide - becomes larger no matter what the people without a need for anonymity do. Consider the extreme case where Tor is on

Tor has the goal of being high bandwidth and low latency, and relays on home connections can be problematic. Many home connections have rather low upstream bandwidth, for example, so that circuits through such relays would be limited to few

I'm not bigiain, but an obvious motivation would be that the more people use Tor for obviously mundane reasons, the more plausible deniability exists for all Tor users. After all, the fact that you're using Tor cannot be hidden,

Another aspect that makes me hopeful about Rust as a way forward for C++ programmers is that it is designed to play well with the C (if not C++) ecosystem. Go is in this weird place where they insist that you have to be 100% Go or not at al

Why did you not address a key point of the comment you were replying to, which was that income taxes allow taxation to correlate with how well one is able to carry the burden? It would be nice (and helpful to the overall signal-to-noise rat

Actually, no. Proving that finding the has is NP-complete would require a proof that any boolean formula (the SAT problem) can be translated into a Bitcoin block such that a nonce yielding a small hash (which is what Bitcoin asks for) would

It means that this section contains example code, but is not actually part of the standard. From an operative point of view, this means that if it conflicts with anything else in the document, the "anything else" takes precedence.
