WikiAlpha by Ciro Santilli 37 Updated 2025-07-16
WikiAlpha is an alternative to Wikipedia, where the main difference is that our deletion policy is far more lenient with regard to notability requirements. Basically, WikiAlpha is a near-indiscriminate collection of information in the form of articles on any topic: you can create an article about the band you just started, your pet dog, yourself, your house - as long as your content does not fall under our speedy deletion policy, it will likely remain on the site forever!
Delft OpenCourseWare by Ciro Santilli 37 Updated 2025-07-16
They have a lot of stuff, well done.
CC BY-NC-SA by default unfortunately, but what can you do...
For synthesized streams like sine we can do it e.g.
ffplay -autoexit -nodisp -f lavfi -i '
sine=frequency=500[a];
sine=frequency=1000[b];
[a][b]amerge, atrim=end=2
'
but it does not seem to accept multiple -i for some reason. So is there a way to open a file from some filter? E.g.:
ffplay -i tmp.wav -i tmp.mkv -filter_complex "[0:a]atrim=end=2[a];[1:v]trim=end=2[v]" -map '[a]' -map '[v]'
fails with:
Argument 'tmp.mkv' provided as input filename, but 'tmp.wav' was already specified.
JAVA_HOME by Ciro Santilli 37 Updated 2025-07-16
This ultimately determines which Java is used by a bunch of tools.
TODO is there a way to update it sanely in Ubuntu: askubuntu.com/questions/175514/how-to-set-java-home-for-java to always match the default java executable?
lspci by Ciro Santilli 37 Updated 2025-07-16
lspci is the name of several versions of CLI tools used in UNIX-like systems to query information about PCI devices in the system.
On Ubuntu 23.10, it is provided by the pciutils package, which is so dominant that when we say "lspci" without qualitication, that's what we mean.
