Yes and no. You can definitely run arbitrary C code on AMD's GCN ISA if you're so inclined (and I expect every other modern GPU, but I know less about those...). There are all the usual assembly instructions, there are pointers, y

Though if it is dynamic programming, then it should be possible for you to answer dogecoinbase's question using not much more computational power than you used to count them in the first place, right? If you think of dynamic programmin

Price controls are fairly widely spread, actually. Some examples that come to mind immediately: taxis in most countries, fees of medical doctors, lawyers, and some other professionals (e.g. real estate agents) in Germany and probably many o

Wealth tends to translate into power. Multi-generation wealth transfer translates into dynasties. Dynasties are the antithesis of democracy. Hence, multi-generation estates are anti-democratic. Of course there is nuance in the extent of the

The article does mention it, though without going into detail - it's called lag compensation.

Apple isn't selling technology, though, they're selling a brand. There are different dynamics in play.

Note that nuclear is also not exactly grid-friendly, since you cannot quickly change the power output of a nuclear power plant. They are useful for base load and nothing else.

I can't speak much for other countries, but for the Germany I suspect that a big part of the difference ultimately derives from a different voting and representation system that is much less focused on individual politicians, and there

Nice explanation - I just wish that people started to include IPv6 setup by default in their examples.

It's not clear without more digging who the original author of the code is. Somebody pointed out that it's from drivers/usb/core/hub.c, but the blame history doesn't go further than the initial commit of the re

The trick is to not squash everything into one giant commit, but to use rebase -i liberally to squash/fixup those typo fix commits where they belong.

Your post is a good example for why cascades are so dangerous. hash1(hash2(...)) is not as secure as the stronger of the hash functions, it may only be as secure as the weaker of the hash functions. Your example is sha1(md5(...)). Well, md5

Keep in mind that most features at 7nm would be quite a bit larger than 7nm. For example, in the 22nm technology I have worked with, a standard wire on the lowest metal layer might be around 40nm wide (higher metal layers use even wider wir

The context here is events originated by a single actor, so wallclock is much more reasonable than in the general distributed system case. You might still be worried about the user accessing your system simultaneously from multiple devices,

Indeed, the expected number of fix points is the same for both permutations and mappings. Quite curious when you think about it, because the distribution of fix points is obviously different! (Consider the case n = 2 for the simplest exampl

The expected number of fixed points in a random permutation is 1. This is an application of linearity of expectation: for a random permutation f of size N and a given input X, the probability that f(X) = X is 1/N, i.e. the probability

The thing is that the first tens of thousands of "self-reproducing robots" do not have to be entirely self-reproducing. If you can produce 99% of a robot's mass from materials available in space (on the moon or some asteroid)

Most importantly, the whole point of having a driver do compilation for you is compatibility. AMD's GCN, for example, currently has three different generations out, and there are small differences in the set of supported instructions

You can get the main motivation for glProgramBinary right from the horse's mouth (i.e. https://www.opengl.org/registry/specs/ARB/get_program_binary... ): This is a very useful path for applications that

No. If their transactions add up to a net outflow, banks use the money that is already in their BoE accounts to make transactions in favour of the BoE accounts of other banks or the FPS (those where the net outflow went to). Since thi

The money in accounts at the Bank of England is created when the BoE buys assets and it is destroyed when they sell the assets again - traditionally, those assets are mostly bonds issued by the treasury (or repurchase agreements or other de

Kind of, but it's a chain. It works by shifting bits through all flip-flops until they've all "dropped out" of an I/O pin. So you don't need any expensive muxes or crossbars. It's actually one of the large

It is fairly easy to develop software in such a way that the correctly initialized version of most structures is mostly zero. If you get in the habit of designing your code that way, calloc is clearly superior: you get much faster initializ

Yeah, this is the part of the essay where I really did a double-take. He actually writes: "Can you have a healthy society with great variation in wealth? What would it look like? Notice how novel it feels to think about that." T

It's interesting that you focus on the individual when it comes to wealth creation. This is not random, and it predisposes you to believe that there is a pie fallacy going on when in fact there might not be one. The truth is that almos

Trying to put in the effort to get a bump in salary is very different from the kind of creation that is the main benefit of startups to society. To counter your anecdote with another one, if only half of the characterization of Steve Jobs

The interesting thing is that if the potential outcome of founding or working at a startup were less, salaries at Google would likely be lower, too. After all, those Google salaries are so high in part because of competition by startups.

Please stay with the facts. Price controls are a very different and much dumber idea than a job guarantee or the basic income.
