  • tiled

    Flexible level editor

    Project mention: How to build maps efficiently | /r/gamedev | 2023-11-27

    A more sophisticated approach may be to use something like Tiled (https://www.mapeditor.org), but it typically takes a lot of code to to parse a Tiled map, so I wouldn’t start there. The exact needs of your game will dictate the approaches you use. Starting simple means you can make good, visible progress getting your game to work. And I’m sure that plenty of real games have shipped where the levels are just text files.

  • mixxx

    Mixxx is Free DJ software that gives you everything you need to perform live mixes.

    Project mention: How to create a playlist of tracks in Ableton Live Lite? | /r/ableton | 2023-06-11

    There are quite a few DJs that use Ableton for DJing (or hybrid sets). Of course, Ableton wasn't made with DJing as its main function in mind but you totally can use it for that purpose and (with some tweaking) do everything and more that would be possible in a dedicated DJing software (like Traktor or Rekordbox or Mixxx)

    There's an issue open for this: https://github.com/gqrx-sdr/gqrx/issues/1104

    I could really use some help from a software build expert. Gqrx and all its dependencies would need to be built in CI with Apple silicon support, and I don't know how to do that.

  • qgroundcontrol

    Cross-platform ground control station for drones (Android, iOS, Mac OS, Linux, Windows)

    Project mention: DJI Virtual Flight (iOS) has been broken for five months | news.ycombinator.com | 2023-09-09

    For Disco you're in luck, there are some really decent ardupilot-based projects out there[1]. Plus, unlike the Bebop camera which is inaccessible via the shell (you can only use the Parrot SDK), the Disco camera can be commanded to stream/record with a few simple commands, and even bound to controller inputs.

    A caveat with the controller: it needs to have custom firmware[2] to get it communicating with ardupilot, and to get the firmware onto the controller you need telnet/adb into it via SkyController→usb→ethernet→usb→Laptop adaptor(s).

    For a ground control system (GCS), there's three to choose from: Mission Planner, APM Planner, and QGroundControl[3] (ignore the rest, use this one).

    For configuring the drone, mission planner is pretty good... but you can also just use MavProxy[4] which is a fantastic commandline program that all the GCSes use in some way, and can even be installed in Termux/Android.

    Project mention: What would be required between my car's wiring harness and a mini-pc/raspi to handle media and map steering wheel buttons? | /r/CarAV | 2023-03-14

    Options are limited. Look here: https://github.com/f1xpl/openauto

  • strawberry

    :strawberry: Strawberry Music Player (by strawberrymusicplayer)

    Project mention: clementine back in AUR | /r/archlinux | 2023-07-03

    Strawberrry (https://www.strawberrymusicplayer.org/) is the fork, but I don't think it will do everything you want as far as plugins go. I would also like something that is Clementine but not 7 years out of date.
