  • Serial-Studio

    Multi-purpose serial data visualization & processing program

    Project mention: Can't find a way to create AppImage for Qt6 programs | reddit.com/r/QtFramework | 2022-10-04

    I recommend moving away from linuxdeployqt, and use linuxdeploy (almost the same name, but without the "qt" at the end). It has a Qt plugin, and it's as easy to use. Check how a real world application is using it, and it's with Qt 6.

  • hotspot

    The Linux perf GUI for performance analysis.

    Project mention: How to interpret a flamegraph? | reddit.com/r/rust | 2022-08-03

    Flamegraphs alone aren't a full picture of what your application is doing, but it can give you hints as to where to look. Another tool I often use is Hotspot which can open the perf.data file and provide more options for filtering and digging into the gathered data beyond the single flamegraph.

  • notes

    Note-taking application, write down your thoughts. (by nuttyartist)

    Project mention: Note taking app written in C++ - an alternative to all those Electron memory-eaters | reddit.com/r/linux | 2022-09-16

  • qgroundcontrol

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

    Project mention: BlueRov2 Firmware Problem | reddit.com/r/rov | 2022-06-03

    I expect you’re running into this issue, although it’s also possible you’re using a QGroundControl version that’s poorly set up to work with ArduSub (or your particular ArduSub version). If you’re not already it’s likely best to use the software version(s) recommended by Blue Robotics.

  • gqrx

    Software defined radio receiver powered by GNU Radio and Qt.

    Project mention: Crossfire low range?? RX Loss & RSSI DBM?? Beeps?? | reddit.com/r/fpv | 2022-10-24

    Some of the Crossfire modules have a rudimentary spectrum analyzer function on them that might help you identify if there are other devices operating in the 900MHz band around that area, but I'm not sure the nano TX is one of them. I have a couple RTL-SDR dongles or equivalent I'd use with GQRX as a cheap spectrum analyzer if possible.

  • edb-debugger

    edb is a cross-platform AArch32/x86/x86-64 debugger.

    Project mention: Desperately looking for graphical debugger (IDE, gdb plugin, you name it) for linux that works similarly to Visual Studio (showing hex, dec, binary, etc). | reddit.com/r/asm | 2022-01-29
  • openauto

    AndroidAuto headunit emulator

    Project mention: [Theme] Kustom UI with tasker integration. Server monitor, Car Page, Traffic Cams and more! | reddit.com/r/kustom | 2022-11-17

    It would take a lot of time don't get me wrong & it can replace your infotainment center with a touchscreen & a rPi3B running OpenAutoPro but if you look at that feature set in the repo you'll see why it's wayyy better & integrates your android on multiple abstraction layers instead of just bluetooth. Plus the user interface is fully customizable with Qt (all open source)

  • antimony

    CAD from a parallel universe

    Project mention: Interesting examples of visual programming? | reddit.com/r/lisp | 2022-08-09
