  • GitHub repo PlotJuggler

    The Time Series Visualization Tool that you deserve.

    Project mention: Ask HN: Software for Time Series Data Manipulation | news.ycombinator.com | 2021-02-17

    Based on your comment, I assume you mean a GUI program for interactive exploration and manipulation, rather than a library?

    This was posted on HN a few months ago and came to mind: https://github.com/facontidavide/PlotJuggler

    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 crow-translate

    A simple and lightweight translator that allows you to translate and speak text using Google, Yandex and Bing.

    Project mention: Ported my translator application to mobile Linux | reddit.com/r/PinePhoneOfficial | 2021-03-12

    The application can translate and speak text using Google / Bing / Yandex. Also it can recognize text from screen using Tesseract library. Available for Windows, Desktop Linux and now for Mobile Linux thanks to Pinephone. The application was written in Qt Widgets (the application was originally developed for the desktop) and switching to QML would require rewriting all the code. So I decided to keep using widgets. It may not look as good as it does on Kirigami, but it is not depends on KDE and works fast. The source code is available on GitHub. You can download rpm (`aarch64`) or deb (`arm64`, apt uses different arch naming conventions) packages for PinePhone from the releases page. For ArchLinux / Manjaro users the app is available in AUR. Hope you like it :)
