  • GitHub repo flameshot

    Powerful yet simple to use screenshot software :desktop_computer: :camera_flash:

    Project mention: A screen recording software that captures and uploads to Gfycat/Imgur | reddit.com/r/linuxquestions | 2021-10-16

    Flameshot has it baked-in.

  • GitHub repo tiled

    Flexible level editor

    Project mention: Digital Graph Program | reddit.com/r/gamedev | 2021-10-12

    Would you ever consider Tiled Editor?

  • Scout APM

    Scout APM: A developer's best friend. Try free for 14-days. Scout APM uses tracing logic that ties bottlenecks to source code so you know the exact line of code causing performance issues and can get back to building a great product faster.

  • GitHub repo nodegui

    A library for building cross-platform native desktop applications with Node.js and CSS 🚀. React NodeGui : https://react.nodegui.org and Vue NodeGui: https://vue.nodegui.org

    Project mention: Electron Adventures: Episode 75: NodeGui React | dev.to | 2021-10-06

    Let's continue exploring Electron alternatives. This time, NodeGui. NodeGui uses Qt5 instead of Chromium, so we'll be leaving the familiar web development behind, but it tries to not be too far from it, as web development is what everyone knows.

  • 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.

  • GitHub repo MuseScore

    MuseScore is an open source and free music notation software. For support, contribution, bug reports, visit MuseScore.org. Fork and make pull requests!

    Project mention: transposing apps | reddit.com/r/saxophone | 2021-09-26

    Musescore. The app is free and awesome. But pay the token cost to join, because the library of scores is worth it, and it's a non-profit, so much of the money goes to the artists.

  • GitHub repo QtScrcpy

    Android real-time display control software

    Project mention: How to boot straight from Bios to samsung dex on a regular laptop? | reddit.com/r/SamsungDex | 2021-09-11

    I was watching a video by u/MRP_yt https://www.youtube.com/watch?v=ns5oaWUFnZ8&t=518s that shows some software that forces windows to recognise galaxy tab devices that don't have dex as a dex device https://github.com/barry-ran/QtScrcpy. Potentially this software could help along with winpe or linux distro in getting this idea to work.

  • GitHub repo olive

    Free open-source non-linear video editor

    Project mention: GraphSCAD – A User Friendly Nodal Editor for OpenSCAD | news.ycombinator.com | 2021-10-10

    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.
