Around room temperature, an ideal silicon transistor has a 60 mV/decade subthreshold swing, which (roughly speaking) means that a 10-fold increase in current requires at least a 60 mV increase in gate potential. There are some techniqu

Yes, someone will redistribute it without charge, but there are still ways you can make money from libre software: • selling physical media (e.g. an installation disk or drive) • selling downloads from a trusted, official server (with the b

"Free" here does not mean "free of charge", it means "libre" (guarantees the four essential freedoms [1]). The common quip is "free as in freedom, not as in free beer". [1] https://www.gnu.

The poorest 70–90% of Americans effectively have no representation – there is almost no correlation between their policy preferences and the voting record of their representatives. On the other hand, enacted policy aligns quite well with th

No problem! Same thing happens to me, where my eyes begin to gloss over things I've written (because I know what I mean to say). Thanks for the submission!

Caveat: this is going to be a meta comment rather than a comment about the topic proper, and so maybe not appropriate for HN, but I think it's worth discussing. > It sounds like you've been hurt by the some terrible management

Did you read the article? If anything, the author is arguing in favor of libraries. I may be misinterpreting your comment, though.

I mean this with sincerity (it's a genuine question). Why write such a lengthy comment telling someone you're dismissing them rather than just dismissing them? Is it to discourage their behavior, or to warn other readers? Or simpl

Although that's sort of like saying "if an ant can't survive being scorched by a magnifying glass, it was probably doomed to burn in the sun anyway". What you're saying may be true – I've no idea. But I'm

It's been a while since I used Lichess anonymously, but I suspect you do need an account to request a server analysis – that way they can limit the number of analyses per day for a user [1]. [1] 40 a day per https://lichess.

Variable-shift perfect hashing (fancy magic) is not especially slower than using pext/pdep, and in any case, there is little value in making move generation more performant. A decent move generator using perfect hashing can run at 40 m

The use of the term "bug" in engineering predates automatic computers by nearly a century; the Wiki article [1] on the topic gives a pretty good summary of its history. [1] https://en.wikipedia.org/wiki/Bug_(e

Modern capitalism is an exhibition of capital's dependency on the state. Without the state, who would enforce a corporation's claims to property? (the products of worker labor, intellectual property, and so on) And empirically,

Great write-up! There may be a typo in section 3: > It will happily retire instruction 6 before instruction 5. If memory serves, although instructions can execute out-of-order, they retire in-order (hence the "re-order buffer")

This is precisely the method used to undo screening and half-toning in one of the labs in 6.003 (the intro signal processing course at MIT). The technique works astoundingly well for its straightforwardness, and the exercise can be a lot of

It's worth noting that the term "exception" is in fact used for traps that aren't interrupts.

It's actually because of the 5-fold repetition and 75-move rules! The game is not necessarily over at 3 and 50 – you merely have the right to claim a draw.

Agreed, but we might be stepping outside the scope of the example. Likely, you can make most examples incorrect if you're allowed to add arbitrary code; I read this section of the article with the implicit assumption that "the thr
