Linux

I haven't used this yet, but the design described in the readme makes it look very convenient compared to the usual array of tools required.

Behold, a Linux maintainer openly admitting to attempting to sabotage the entire Rust for Linux project:

https://lwn.net/ml/all/[email protected]/

The good news is this doesn't affect drm/asahi, our GPU driver. The bad news is it does affect all the other drivers we're (re)writing in Rust, two so far with a third one coming.

Another choice quote, calling R4L "cancer": https://lore.kernel.org/lkml/[email protected]/

Personally, I would consider this grounds for removal of Christoph from the Linux project on Code of Conduct violation grounds, but sadly I doubt much will happen other than draining a lot of people's energy and will to continue the project until Linus says "fuck you" or something.

As for how to move forward, if I were one of the Rust maintainers, I would just merge the patch (which does not touch code formally maintained by the dissenter). Either Linus takes the pull, and whatever Christoph says is irrelevant, or he doesn't, and R4L dies. Everything else is a waste of everyone's time and energy.

Edit: Sent in my 2 cents: https://lore.kernel.org/rust-for-linux/[email protected]/T/#m1944b6d485070970e359bbc7baa71b04c86a30af

I've inherited a systemd service and it uses BindReadOnlyPaths to make certain paths available to the service (doc)

A bind mount makes a particular file or directory available at an additional place in the unit's view of the file system. Any bind mounts created with this option are specific to the unit, and are not visible in the host's mount table.

The service is running using a specific user and I would like the user to access those read-only paths outside of the service. Is there an possibility within systemd that would allow me to do that?

Edit: solved it with a systemd bind mount

I use Ollama with continue.dev in code-server, and I wanted a way to hit Cntrl-Shift-Alt-T to get a "top" of sorts that would show CPU, IO, GPU, loaded models, and logs, all in one place quickly.

Set up the below screenrc file and created the shortcut above in Debian. Tab switches between CPU and IO, and Cntrl-a q quits all screens and closes the Gnome shell.

Screenrc:

termcapinfo xterm* ti@:te@
startup_message off
defscrollback 10000

bind q eval "kill" "quit"
caption always "%{= rw}%-w%{= KW}%n %t%{-}%+w"
defbce on

# Start htop and focus
screen -t "HTop" htop
focus

# Split horizontally to put nvtop under htop
split
focus
screen -t "NVTop" nvtop

# Split vertically to put ollama next to nvtop
split -v
focus
screen -t "Ollama PS" watch -n5 'docker exec -ti ai-ollama ollama ps'

# Split horizontally to put logs underneath ps
split
focus
screen -t "Ollama logs" bash -c "docker logs -f --tail 100 ai-ollama | grep -Ev '\"/api/ps\"|\"/\"'"

# Resize PS, then get back to logs
focus up
resize -v 6
focus down

# Get back to htop
focus

The atop script that runs with Cntrl-Alt-Shift-T:

#!/usr/bin/env bash

if [ "${1}" = "new" ]; then
    gnome-terminal --geometry=200x50+0+0 --maximize -- /data/system/bin/atop
else
    screen -c /data/system/setup/common/screenrc-status
fi

Happy to share my htop config as well if anyone wants it.
