Update in 2024
In 2024 I'm actually having a good time using mupdf.
About my experience with mupdf:
It's written in C, but you can use it in many ways. Command line, python lib (pymupdf), js, and others.
I still coundn't find issues that I had with other tools and weird broken PDFs, so I'd say pretty good.
I was looking for a SVG Optimizer tool, cli tool preferably. SVG generated when converting from pdf to svg are kinda big.

SVGO is awesome, you can get thin svg files from it. =]
It's a cli tool, but keep in mind it's a nodejs tool, so you have to install node, it doesn't have an official compiled binary. https://github.com/svg/svgo
brew install ImageMagick
ffmpeg -ss 14:55 -i video.mkv -t 5 -s 480x270 -f image2 %04d.png
- -ss 14:55 gives the timestamp where I want FFmpeg to start, as a duration string.
- -t 5 says how much I want FFmpeg to decode, using the same duration syntax as for -ss.
- -s 480x270 tells FFmpeg to resize the video output to 480 by 270 pixels.
- -f image2 selects the output format, a series of still images — make sure there are leading zeros in filename.

The STM32CubeMX tool is written in portable java, but unfortunately it is distributed as a Windows executable embedded in a Windows installer.
To install it on Linux:
sudo java -jar SetupSTM32CubeMX-4.11.0.exe- install the tool somewhere in your home, eg:
/home/you/stm32/cubemx sudo chown -R you:you /home/you/stm32/cubemx
