The tools that are stroked out are the ones I used in the past but not so much anymore in favor of others.

Operating Systems

  • Windows 7/8/10
  • Ubuntu GNU/Linux
  • Linux Mint
  • Raspbian with Pixel, Raspbian Lite

I still have to use Windows in school and at work, and my OS actually looks like a dark macOS, so I'm not completely unfamiliar with that too

IDEs/Editors

  • PyCharm for bigger Python Projects > 3 files
  • Android Studio for Android Apps
  • Brackets Atom for web development
  • Visual Studio at work
  • Notepad++ nano for all the other things, not vi

Web development

  • Sass, Sass, Sass!
  • Webpack 2 for speed
  • ESLint
  • Babel for some projects
  • A bunch of Atom plugins for automation and integration of the above
  • Web services including "Am I responsive" and Google PageSpeed

Other

  • Git. Even though I'm not a git expert, I use it for some while now with GitHub and Gitlab. I'm running my own, slooow GitLab server on a Raspberry Pi 2 which was laying around.
  • Almost forgot mentioning the Terminal, often more instances than I can control. And yes, I know that most Linux Terminal applications can have multiple Tabs open, same as the file manager. Still Windowfied (No, i actually managed using tabs lately...)

For now that's it. I bet this list is far from being complete, I will edit whenever I have something new in mind.
