Project mention: Autoconf makes me think we stopped evolving too soon | news.ycombinator.com | 2024-04-03A better solution is just to write a plain ass shell script that tests if various C snippets compile.
https://github.com/oilshell/oil/blob/master/configure
https://github.com/oilshell/oil/blob/master/build/detect-pwe...
Not an unholy mix of m4, shell, and C, all in the same file.

These are the same style as a the configure scripts that Fabrice Bellard wrote for tcc and QEMU.
They are plain ass shell scripts, because he actually understands the code he writes.
https://github.com/qemu/qemu/blob/master/configure
https://github.com/TinyCC/tinycc/blob/mob/configure
OCaml’s configure script is also “normal”.
You don’t have to copy and paste thousands of lines of GNU stuff that you don’t understand.

Project mention: Building a faster hash table for high performance SQL joins | news.ycombinator.com | 2023-12-20Worth pointing out that this can depend a lot more on fiddly details than you might expect. In particular, you're dealing with a small fixed width allowing the hash to be stored in the table instead of the key. The article emphasizes variable-length keys, and I don't see any specialization on key sizes (if 4- and 8-byte keys aren't common then this makes sense; if they are then I'd expect dedicated table code for those sizes to be valuable). And set lookups are also just a bit different from value lookups. I think these cases are different enough that I have no idea if the results would carry over, although I can see how the bidirectional approach would reduce probing more than RH which seems good.
...and since I've done a lot of work with Robin Hood on small-key lookups, I can point out some little tweaks that have made a big difference for me. I have 8-byte lookups at just over 3ns/lookup[0], albeit at a very low load factor, typically <50%. A key step was to use the maximum possible hash as a sentinel value, handling it specially in case it shows up in the data. This way, instead of probing until finding an empty bucket or greater hash, probing just finds the first slot that's greater than or equal to the requested key's hash. So the lookup code[1] is very simple (the rest, not so much). The while loop is only needed on a hash collision, so at a low load factor a lookup is effectively branchless. However, these choices are specialized for a batched search where the number of insertions never has to be higher than the number of searches, and all the insertions can be done first. And focused on small-ish (under a million entries) tables.
