@klaatuFunny you should mention Chromebooks on #gnuworldorder, because I just got a new one just a couple of weeks ago for GPU driver development:https://www.google.com/intl/en_us/chromebook/device/lenovo-chromebook-duet/I'm still using Chrome OS as I haven't got a usb-c to usb-a adapter, but I already built a new 5.10-rc kernel for it, which took all of 13 minutes on the 8 cores of the MT8183, a lot faster than 40 minutes on my old Chromebook.

@klaatu When questioning Chrome OS design decisions, it's important to remember that the priority is on security.Because of this, the Linux support uses a custom VM image so the VM (crosvm) can be simpler and have a smaller attack surface. The VM image does not support root, but the chronos user can manage LXD containers. Btrfs is used for the filesystem image (it's at /home/root/*/crosvm/*.img), though the host kernel doesn't have btrfs compiled in, so it can't be directly mounted. :(

@klaatu File sharing uses 9p for Chrome OS to Linux sharing, and sshfs for the other direction.9p for sharing on CrOS has the advantage that sshd doesn't need to be running on the Chrome OS side, and using sshfs for sharing back into CrOS means that the client is running as an ordinary user and can't expose files as setuid etc.You can enable accelerated OpenGL through virgl by enabling "Crostini GPU support" in about:flags.Microphone support can be enabled in the Linux settings.

@klaatuBy default, everything is mounted with noexec except for /usr/local, so if you try installing your own executables, put them there.You can avoid the beeps on startup with ctrl-d.To hard reboot, you can hit Alt+VolumeUp+R, which is useful as you can read the kernel logs before reboot as /sys/fs/pstore/console-ramoops-0.

@klaatu Chrome OS uses its own audio server, CRAS. You can disable/enable it with 'sudo stop/start cras'.I managed to get jackd running from CrOS, but netjack couldn't see the Linux VM. Maybe it would work if I used the proper hostname (penguin.linux.test) instead of localhost...I should also try PipeWire, which I've had good experiences with on my old Chromebook which runs Void Linux.(PipeWire is aiming to be the replacement for both JACK and Pulse, and it provides its own libjack.so).

@klaatu The android support in just in a container, with no VM (yet...).There is a "Show all Play folders" in the file manager settings, so you can see what shared folders actually exist in the android container.You can find the android storage at /home/root/*/android-data/data, useful for extracting files stored in android apps.The actual root is at /opt/google/containers/android/rootfs/root/, but is immutable unless you do tricks with 'mount --bind'.

@Seirdy @xerz Except that many container engines are *not* designed to run as setuid… bubblewrap is one that is explicitly designed to be used as such (or with unprivileged namespaces if the binary is not setuid).

@iron_bug @alcinnz Modern GPUs (i.e. anything supporting WebGL) have enough isolation that malicious code shouldn't be able to do anything worse than a denial-of-service by causing GPU timeouts.(But even that can kill the display server with some drivers.)It's not like any GPU would have a vulnerability allowing modification (and possibly reading) of another process' graphics memory, right? Right?(Hint: some do)

@seb Especially when you don't set a password so it lets you execute the command anyway after three fingerprint mismatches.

@alcinnz @be @ilovecomputers https://github.com/browsermt/bergamot-translator seems to be what you want.But it appears that the only supported platforms are x86 and WASM, getting it to work on other architectures might be a bit of work.

@vik @lightweight @thelinuxEXP Who needs USB drivers when WebUSB exists?(Though I've found that WebUSB in Chrome on Windows is a buggy mess compared to Linux. Okay, maybe I was trying to abuse parts of the USB spec to do things, but still…)

@thor Actually, you can see that it is moonrock:— it is grey— it has craters like the moon does— it is round like the moon

@thor In New Zealand, swimming lessons are very common. I don't remember anything about saving drowning people though; perhaps the assumption is that if you don't know how to swim, it's your own fault if you drown…

@thor Perhaps the takeaway from that would just be that "Eccentricity level" is not the correct metric to use?

@neanderthalsnavel @thor I think you're supposed to *listen* to it, not watch it.
