When the Damore memo came out, people have calculated that to explain the only 20% women working for google, the average IQ of google engineers needs to be 160. That is laughable.

An ASCII char would have its MSB 0 in UTF-8, and any byte in UTF-8 which is not a single ASCII char has its MSB as 1.

What? No. The c in cpython was not meant to signal performance. The c was added after alternative implementations were created to mean "the original/reference implementation". Python's competitors perl ruby and php are l

Eh, copyright law in most countries is the way it is because of pressure from the richest countries (like the US) to conform or lose all trade (or even get a visit from a Marine expeditionary force).

ppmd will get you better compression on text (better than zstd and even better than lzma), but it is slow to compress and decompress. Use `7z a -m0=PPMd demo.7z demo.txt`

This sounds really slow to me. What is the overhead of "disable EPT and go back to shadow paging", or what was the performance win of EPT?

Linux kernel has a compatibility guarantee to the user space visible API, so static binaries will continue to run. If the static binary is so old it does not know about vdso and uses regular syscall to query time, it will be slowed down.

I don't doubt your story, but modern CPUs can perform AES-GCM at gigabytes per second per core (5GB/sec on my laptop). Disk encryption is a different block cipher mode, but it shouldn't be much slower. So if implemented corre

But come on, if US intelligence agencies recovered metallurgy from Russian hypersonic missiles or something like that, why would they use UFO for cover? And why would they store it outside of AFRL? I think it's just a way to funnel tax

If you use 1024 bit DH with a common group (old/misconfigured web and email servers do this) then it is suspected nation states can break the DH, get the shared symmetric key and decrypt all traffic. For ECDHE over P-256, they would ne

SSL and TLS before 1.3 had a key exchange mode that used RSA encryption, without any DH, DHE, ECDHE, etc [1]. The client would generate a secret, encrypt it to the server's public key (from the certificate) and send that to the server.

Why is Arabic twice harder than Hebrew, as hard as Chinese? Hebrew and Arabic are closely related (the alphabet (well, an abjad) is almost the same, grammar is almost the same).
