this is extra tricky because they did not specify the exact kernel. mainline could be any of the kernels tagged as stable that you can build from linus’ git tree. i know that in the past you could run a mainline linux on intel 368 chips but today you probably can not because official support was dropped a while ago.
JXL rocks! Its so sad that some browser vendors are seemingly trying to kill it. It has basically all the features you could want for a JPG replacement and also has a reference implementation that implemented all that stuff as free software and with good documentation without any patent bullshit attached.
woah this is awesome!
maglevs need classical wheel systems anyway because there might be a power outage, so simply having wheels that are compatible with the local rail system is a brilliant idea.
add in a tiny propulsion system so they can use the normal tracks at low speed without the help of the maglev tracks and you can sort of blend the two systems together in critical locations like switches and train stations.
OpenWRT does not use liblzma or systemd so i think that one is pretty safe. I would also be surprised if Android included OpenSSH server binaries in that way.
