The one-liner:

dd if=/dev/zero bs=1G count=10 | gzip -c > 10GB.gz

This is brilliant.

No, but that's an interesting question. Ultimately it probably comes down to hardware specs. Or depending on the particular bot and it's env the spec of the container it's running in

Even with macos's style of compressing inactive memory pages you'll still have a hard cap that can be reached with the same technique (just with a larger uncompressed file)

How long would it take to be considered an inactive memory page? Does OOM conditions immediately trigger compression, or would the process die first?

[–] tdawg@lemmy.world 1 points 1 day ago

So I'm not an expert but my understanding is the flow is roughly:

  1. Available memory gets low
  2. Compress based on LRU rules
  3. Use swap
  4. OOM

So it's more meant to be preventative afaik
