Discogs Updated +Created
The IMDb of music! They actually have a reputation system apparently. And sneaked in a vinyl marketplace as well.
The website name sounds like play on words: disc + hog, with hog in the sense "memory-hog", i.e. something that consumes all your computer's memory.

Discord email notifications Updated +Created
Discord is useless if you want to participate in more than one large group because of this. It is impossible to get email notification for selected threads you care about.
Ubuntu 21.10 does not wake up from suspend Updated +Created
Does not happen every time, only some times. Can't figure out why. Usually happens when has suspended for a longer time.
bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-470/+bug/1946303 sounds like a likely report, Nvidia driver version 470, but can't find those error messages anywhere. The last line of:
journalctl -o short-precise -k -b -1
once was:
PM: suspend entry (deep)
which is when sleep starts.
This suggests that it is not a video bug then, seems that it is not waking up at all? Gotta try to SSH into it. OK. I did SSH into it, and that was fine, so it is just the video that won't start.
PM: suspend exit
bugs.launchpad.net/ubuntu/+source/linux/+bug/1949977 is another possible bug, based on kernel version. I'm running 5.13, which is one of the failing versions on the report. Can't find any interesting dmesg though.
In another crash:
journalctl -o short-precise -k -b -1
had the following interesting lines:
nvidia-modeset: WARNING: GPU:0: Lost display notification (0:0x00000000); continuing.

Discrete logarithm Updated +Created
NP-intermediate as of 2020 for similar reasons as integer factorization.
An important case is the discrete logarithm of the cyclic group in which the group is a cyclic group.
Discrete logarithm of the cyclic group Updated +Created
This is the discrete logarithm problem where the group is a cyclic group.
In this case, the problem becomes equivalent to reversing modular exponentiation.
This computational problem forms the basis for Diffie-Hellman key exchange, because modular exponentiation can be efficiently computed, but no known way exists to efficiently compute the reverse function.
DNA detection Updated +Created
DNA detection means determining if a specific DNA sequence is present in a sample.
This can be used to detect if a given species of microorganism is present in a sample, and is therefore a widely used diagnostics technique to see if someone is infected with a virus.
You could of course do full DNA Sequencing to see everything that is there, but since it is as a more generic procedure, sequencing is more expensive and slow.
The alternative is to use a DNA amplification technique.

Erdős' conjecture on powers of 2 Updated +Created

Unable to lock screen on Ubuntu Updated +Created
Happened on P14s on Ubuntu 23.10, which started with fresh Ubuntu 23.10 install.
However it did not happen on Lenovo ThinkPad P51 (2017) also on Ubuntu 23.10 which had been upgraded several times from God knows what starting point... At first one had X11 (forced by Nvidia drivers) and the other Wayland, but moving to p14s X11 changed nothing.
Both were running GNOME Display Manager.
Same happens with Super + L, but also CLI commands: askubuntu.com/questions/7776/how-do-i-lock-the-desktop-screen-via-command-line

Some of the contributions are subjectively self evaluated based on:
  • How many significant lines changed (no indentation changes, moves, mass refactoring, trivial tests, etc.):
    0only trivial changes

    2< 150
    3
    150
  • How hard it was to make it. 4 algorithmic lines are harder than 100 web development/documentation lines.
