systemd have its own UUID generator:

systemd-id128 new --uuid -p

also kernel itself provides a UUID gen:

/proc/sys/kernel/random/uuid

simple linux prog that will take .zip file and print it as 16-bit unsigned integers (U16).

VT kmssink \ gstreamer experiments:

run that command run under VT:

 sudo gst-launch-1.0 videotestsrc ! kmssink

kmssink is a simple video sink that renders video frames directly in a plane of a DRM device.

check if you post-quantum ready

ssh -vv -o KexAlgorithms=mlkem768x25519-sha256 user@host

that key exchange default from openssh v10

about some fonts (monospace):

For people from the future: The ones that looked similar to FixedSys were:

Mx437_DOS-V_TWN16, Mx437_DOS-V_TWN19, Px437_DOS-V_TWN16 and Px437_DOS-V_TWN19

Fast way to test new font without changing anything in settings (using xfce4-term):

xfce4-terminal --disable-server --font="Fixedsys Excelsior 24" --hold --command fastfetch

transformer music, free, without sms, and wet pussies:

play -n synth 50 sine 50

play -n synth 50 sine 50 sine 52 vol 0.7

electrical transformer beat

its even funny with telegram rec:

play -n synth 50 triangle 220 triangle 222 triangle 262 triangle 264 triangle 330 triangle 332 tremolo 0.1 0.4 vol 0.6
