I guess there is also the approach, not favored by cryptography engineers, which is to decide for some projects that you don't care about efficiency, you would securely combine too many primitives. Like stream chunks for bulk encryptio

Every P-256 or X25519 ECDH operation uses a new ephemeral single-use key breaking which is about as hard as brute forcing AES-128. Global bitcoin hash rate is something like 90 bits per year. People think NSA doesn't have more hardware

Eventually a private key will leak, and without forward secrecy, that private key will probably decrypt all past messages to that person, and all future messages to that person, until they give all their correspondents a new key. With email

He doesn't want to ignore the error, he wants exceptions-like behavior where the exceptions just propagate up by themselves if you don't catch them inside the function. Like Java or Python exceptions.

It's obsolete. DEFLATE format is limited to 32KB LZ window with huffman coding. Zstd can use a much larger window (8MB recommended) and a much better entropy coder: https://github.com/Cyan4973/FiniteStateEntropy

The designers leave themselves an ability to override any instruction using the microcode so they can patch any instruction. They don't use the microcode only to implement complex instructions that require loops.

You can hand out uuidv4 to clients without revealing anything.

Even if you want to use a compression algo for this, you probably want to use lz4 with optimal parsing, you don't need the entropy coding and you don't need the checksum something like gzip (or more modern zstd) provides.

Because AESNI and CLMUL, AES-GCM is faster than a SIMD implementation of ChaCha20Poly1305. In theory, ChaCha20 is overkill, 8 rounds would have been enough and people do use 12 rounds for disk encryption.

order by stored uuidv4 will get you the same rows the next time you run it. If you sample using where random() < 0.001 (or something like that) you'll get different rows each time.

Some libraries have x86 SIMD code but no ARM SIMD code, so benchmarking real world use cases you compare SIMD vs scalar code and x86 is much faster. Server side libraries for ARM are a less mature situation than x86.

I don't think so. There is no pipeline for them. Nobody can make a career of working temp jobs for long hours and make 15K a year. These people need to switch careers. Professional managements don't hire from among the PhDs who we
