On a more generic front, there's always libeatmydata which forcibly disables fsync. I've used it in the past for doing, eg, faster database restores. Run mysqld under it, do the restore, manually force a sync, shut down MySQL, res

Sorry, I guess I'm coming across wrongly somehow? I think 120m towers are crap as an energy storage solution. Maybe they could shove them inside skyscrapers that are being built, but that seems like a reach, especially given the size

I was experimenting with some dynamic programming 0/1 knapsack code last week. PyPy available through the distro (7.3.9) was making a reasonable speed up, but not phenomenally. Out of curiousity I grabbed the latest version through pye

It's a python runtime that contains a JIT, as a result it can be phenomenally faster. Like with any JITted runtime, it depends a bit on what your code is doing, and how long you're running it for as there is a little (but honestl

I appreciate there is nuance, and some checks would be computationally expensive, but something like training data and evaluation data being literally identical seems like it would be pretty straightforward to check for and a very simple qu

Well... yeah. S3 has checksums and all sorts of fixity checks right throughout. At no stage do they ever rely on a single mechanism. If there's one thing they're insanely paranoid about, it's data correctness and durabilit

We came up with that idea in Glacier during the run up to April one year (2014, I think?), half jokingly suggested it as an April Fool's Day Joke, but Amazon quite reasonably decided against doing such jokes. One of the tag line ideas

Yes, I remember tcp checksumming coming up as not sufficient at one stage. Even saw S3 deal with a real head-scratcher of a non-impacting event that came down to a single NIC in a single machine corrupting the tcp checksum under very speci
