    Here’s the source thread.

    Tldr: someone wants to put rust in the dma part of the kernel (the part that accesses memory directly)(it’s a memory allocator abstraction layer written in rust which rust code can use directly instead of dealing with the c allocator abstraction layer), is told that rust should use the extant methods to talk to the c dma interface, replies that doing so would make rust programs that talk to dma require some more code, gets told “that’s fine. We can’t do a split codebase”. The two parties work towards some resolution, then hector martin comes in and acts like jerk and gets told to fuck off by Linus.

    Martin is no lennart poettering but I don’t try to see things from his perspective anymore.

    It’s worth noting that Linus’ “approval” of rust in the kernel isn’t generally seen as a blanket endorsement, but a willingness to see how it might go and rust people have been generally trying to jam their code everywhere using methods that rival the cia simple field sabotage manual.

    I don’t think it’s on purpose (except for maybe Martin) but a byproduct of the kernel maintainers moving slowly but surely and the rust developers moving much faster and some seeing the solution to that slow movement as jamming their foot in the door and wedging it open.


  • It’s not p2p but at least many years ago:

    SMS.

    If the Internet outage is local then the towers would still work and you’d be able to get texts. I went through a few storms where wired home internet was down, the towers weren’t giving me a data connection (no mobile web browsing or anything), but I was able to send and receive texts.

    If you really care about what you’re asking after, do what someone else said and get a radio license. It’s 150 year old technology and every time something happens radio operators pop up some kind of emergency communications or bridge to the internet through repeaters or something.
