i am playing around with random number generation and found that the same number kept being generator regardless of what seed i used. not sure if a bug, but definitely surprised me.
i was able to produce this is a minimal example https://github.com/JanCVanB/roc-random/issues/14. i realized i posted in the wrong repo, but the repo for the fork im using (https://github.com/lukewilliamboswell/roc-random) doesn't allow issues
Luke Boswell (Dec 17 2023 at 19:47):Fuxed that, should be able to add issues. This looks like the first one :grinning_face_with_smiling_eyes:
Luke Boswell (Dec 17 2023 at 19:50):I'm not sure how quickly I'll be able to investigate this issue. I'm definitely not familiar with roc random, I just revived @JanCVanB work and packaged it so it was useable.
Lorentz Lasson (Dec 17 2023 at 19:58):ah cool, moved the issue over :+1: no rush at all from my side, i've worked around it
is there a recommended way to generate seeds during runtime? didnt find anything in the docs so just went with Utc.now millis
Luke Boswell (Dec 17 2023 at 20:12):Not sure about reccomend or anything, but I've been using Utc too
Luke Boswell (Dec 17 2023 at 20:17):What platform are you using? Maybe we should add a Task for getting properly random seeds? That's a pretty easy to do if your interested.
jan kili (Dec 17 2023 at 20:52):I've been unavailable to the Roc community for a year or so now, but I'm slowly re-entering! I hope to take a look this week :)
jan kili (Dec 17 2023 at 20:53):I didn't do any work on seed generation, just left that to the consumer - millis sounds reasonable
jan kili (Dec 17 2023 at 20:55):Luke, did I ever get you the permissions/config you wanted? I'm afk today, but I imagine there's some friendly PR from you that I've completely ghosted
jan kili (Dec 17 2023 at 20:56):Lorentz, nice job finding a workaround
Lorentz Lasson (Dec 17 2023 at 21:12):i'm on linux.
a task to get a properly random seed sounds lovely :heart:
jan kili (Dec 17 2023 at 21:15):Unfortunately there's no such thing ;)
jan kili (Dec 17 2023 at 21:16):If you had it, you wouldn't need the library!
