  • betaflight

    Open Source Flight Controller Firmware

  • Project mention: GPS lost signal suddenly and recover | /r/fpv | 2023-12-09

    Op, it seems your gps has m10 chipset, am I right? Because the m10 is not supported on betaflight. Or rather, it works, but betaflight sets it up incorrectly. There is a fix, but not released yet, or you have to set gps to 10hz in ucenter and disable auto convig in betaflight (and lose some features). See https://github.com/betaflight/betaflight/issues/12737 for more information. This might not be your issue, but it might be related.

  • htop

    RIOT-OS is somewhat popular in academia, it tries to be very approachable but there are still plenty of low hanging fruits with all kinds of hardware and you can use it for software and thesis projects.

  • LXC

    LXC - Linux Containers

  • Project mention: LXD Moves into Canonical | news.ycombinator.com | 2023-07-06

    I hope this doesn't affect LXC negatively.

    LXC and LXD share plenty of contributors.

    https://github.com/lxc/lxc/graphs/contributors

    https://github.com/canonical/lxd/graphs/contributors

    I use an "unprivileged LXC container" setup on several Debian bullseye hosts. It works fantastic, and each LXC container feels like a real server.

    Compare that to Docker's "one-container-one-process" philosophy, reinventing the wheel by awkwardly composing multiple containers.
