Ask HN: What are you currently trying to figure out?

3•gooob•1y ago
i'm trying to figure out why elden ring started stuttering and freezing during gameplay recently, and why the windows operating system has so many little dumb things wrong with it.

how's that going? what are your current options?

How to build a segmentation model based on a sample of data that needs to be representative of the population.

Trying to figure a workaround in ksh for space-delimited filenames:

  for f in $(ls "/mnt/dir"); do
    cp -v "$f" /elsewhere
  done
Because -R doesn't handle retries when cp(1) errors out intermittently (USB MTP to phone). I don't remember it being this hard in bash, or Android just is like this. Hopefully can figure it out without going to perl or C. Maybe dump(8).

Even though 54 GB partition created, it only takes up 22 GB or so. Either missing a lot of files or FFS compacts it well.

turtleyacht•1y ago
Pipe and read per line:

  ls /mnt/dir | while read line; do
    cp -v "$line" /elsewhere
    # substitute with something fancy
    # [ $? -eq 0 ] || cp -v "$line" /elsewhere
  done

If there’s transmission errors, I would recommend using rsync rather than cp. that will keep transferring and running checksums until everything matches.
turtleyacht•1y ago
Thank-you. After installing openrsync(1) (and rsync), files transferred for a bit but failed and dumped core with error 138 (bus error). Maybe a quirk with OpenBSD 7.6, or interaction between simple-mtpfs and the fusefs mount.

In the meantime, after a few retries, the failures are written to a log for a second sweep.

MD5 check helps skip extra copying, but it's overall much slower. It seems okay for a long-running batch job; maybe something we can return to after getting the pictures to display.

The pattern is like

  cp ... || \
    { sleep 2; cp ... ; } || \
    ... || \
    ... || echo "$file" >> retry.log
Not the best way. It has failed before all four times. Going to let it run overnight to see if it completes.

navigating personal 'unemployment' while obsessively hoarding whatever money I can to run experiments / train, finetune models to leverage RL and environment-building in order to use computers, learn tasks, learn from each other, and scale to managing companies (simple, SaaS at first, and eventually, potentially to real-world operations downstream task sets)

I arrived tired to a pre wedding photo shoot this morning, my prospective wife yelled at me, and cancelled the shoot. I walked out because I don’t like people yelling at me. So I am trying to figure out whether I still want to marry her.
