    Project mention: A good screenshooting tool for a minimal install of archlinux | reddit.com/r/archlinux | 2021-06-13

    Also chiming in here to sing praises for flameshot. It's FOSS too: https://github.com/flameshot-org/flameshot

  • GitHub repo tiled

    Flexible level editor

    Project mention: Professional dungeon design | reddit.com/r/DnDGreentext | 2021-06-08

    There is actually a new GUI framework based out of Qt (a C++ GUI framework) that I have found recently : https://docs.nodegui.org/

  • GitHub repo LiteIDE

    LiteIDE is a simple, open source, cross-platform Go IDE.

    Project mention: CodePerfect 95 – A fast IDE for Go | news.ycombinator.com | 2021-06-07

    If this is the kind of thing you are interested in, I would strongly recommend LiteIDE:



    It's actively developed, FOSS (LGPL), native C++ (Qt), runs on Windows/macOS/Linux, supports go.mod, and uses gocode/gotools for intellisense instead of gopls. It has integrated debugging, go to definition/usages, and some refactoring support.

    Project mention: I'm new | reddit.com/r/saxophone | 2021-06-07

    Join musescore. The software is free and awesome, and the download library is large and a non-profit operation.

  • GitHub repo olive

    Free open-source non-linear video editor

    Project mention: Lycopene supplements UK | reddit.com/r/olive | 2021-05-27

    Yes: You're lost. This is the subreddit for the Olive Video Editor: https://github.com/olive-editor/olive

  • GitHub repo Mapbox GL

    Interactive, thoroughly customizable maps in native Android, iOS, macOS, Node.js, and Qt applications, powered by vector tiles and OpenGL

    Project mention: Maps Offline? | reddit.com/r/gnome | 2021-02-15

    But vector tiles is indeed the way to go, but it's also much more complicated. Everyone that has worked on Maps so far has done it either as a SoC / Outreachy student or on weekends and evenings. Look at https://github.com/mapbox/mapbox-gl-native if you want to get a feel for the complexity of a client side implementation of rendering vector tiles.

  • GitHub repo qTox

    qTox is a chat, voice, video, and file transfer IM client using the encrypted peer-to-peer Tox protocol.

    Project mention: [Filter] Block "New! Messenger App for Windows" on Facebook Messenger | reddit.com/r/uBlockOrigin | 2021-05-11

    Facebook zucks and I rate it 0/10, do not use if at all possible. Unfortunately, non-tech-savvy people don't tend to use alternatives. Best I can recommend at the moment is DeltaChat, since everyone's got email, or qTox for video and audio.

    AndroidAuto headunit emulator

    Project mention: [Discussion] Android Auto Alternative or Replacements, or Workarounds? | reddit.com/r/fossdroid | 2021-05-05

    I dunno if this is the proper place to ask about this, but; we already know Android Auto is pretty locked down to Googly's services, and requires their apps for the extra functionality. I'm aware of some progress being made to work around it; someone did get Android Auto Running in MicroG as well as AACS and the wonderful reverse engineered OpenAuto

  • GitHub repo Serial-Studio

    Qt Base (Core, Gui, Widgets, Network, ...)

    Project mention: Copying data files to the build directory with qmake | reddit.com/r/QtFramework | 2021-04-12

    The one I was thinking about is not INSTALLS, but COPIES. See an example in Qt's docs for how to use it, and the implementation in case you want to know what it does.

  • GitHub repo otter-browser

    Otter Browser aims to recreate the best aspects of the classic Opera (12.x) UI using Qt5

    Project mention: Vivaldi 4.0: Vivaldi Translate and Vivaldi Mail, Calendar and Feed Reader | news.ycombinator.com | 2021-06-09
