A super deep and informative post as always Victor. I'm still digesting it, also cross-referencing it with the ZFS section of your Hetzner drive failure write up of December 13th. https://vadosware.io/post/handling

I'm interested in learning more about the performance possibilities of mmap for the case read-only X 64-bit-only and found this interesting article by Justin Willmert [0] from 2020-11-05 on using the Linux-specific MAP_POPULATE flag to

Apple also has a question mark attached to its commitment to privacy in China. Even though the Twitter thread below is by a NYT reporter, it sounds directionally credible given how embedded Apple is in China, both from a manufacturing point

I understand why Brave are subject to the Apple AppStore TOC. What I am not clear about is why Brave would be subject to YouTube’s TOC.

Essentially then, the LU decomposition of P is just the matrix form of Vandermonde’s - which I recall now. So I’m surprised that Timothy Gowers didn’t just write that down.

I've watched the video as far as Timothy Gowers sets out the problem. Now here's my attempt at a mental-arithmetic solution plan: 1. For any n, attempt to do an LU decomposition of the Pascal matrix P into the product of lower-tr

Actually, they do give a comprehensive analysis of infection points and singularities for the cubic polynomial segment with given endpoints, tangents and magnitudes. There's a diagram of square with some (maybe superficial) similarity

Yeah! If you go back far enough real programmers didn’t see the point of this new fangled assembly language making things too easy. https://forum.osdev.org/viewtopic.php?t=28852

Thanks for those ideas.

IIRC, in your thesis, the method of approximating Euler spirals is exact at the midpoint and has errors at the end. Say if instead, one wanted the reverse - an Euler spiral approximation that was exact at the endpoints and was allowed error

Fair enough - aware that you're not a fan of biarcs from your thesis. >The simplicity of the arc as primitive curve has some nice features though, for example the fact that parallel curve is nearly trivial. Yes. Also, IIRC, Alexey K

You probably didn't. You seem a concientious author and I thought that, from having read your thesis, you were probably not aware of the book and might like to know about it. There's interesting material in there on nonlinear spli

Aren't these sort of articles from tech media whataboutism to distract from their own lack of diversity? This article gives some perspective: https://oonwoye.com/2020/07/31/tech-journalism-is-less-diver..

Thank you for that reply - particularly the informative explanation. I was sort of assuming it must be a reference to the parallel schemes because with SHA256(MD5(x)), once you had an MD5 collision you would be done.

For clarity, which part of petertodd's comment are you replying to? (I'm learning a little cryptography from this thread, so the above is a straight question.)

Actually, I'm generally pro-freedom where there is no obvious victim. But that's not true in this case. The way I see it is you can suffer the more modest loss of freedom of mask wearing now. Or you can ignore that and have loc
