* jinja2 as general purpose templates * org mode * yaml (sorry but I like it and write it without more errors than the other formats) * docker / docker compose * rss * rofi -dmenu * .http files to keep requests * sentry * ansible * atom hydrogen - the most comfortable programming environment where I can execute my code as I write it, there are other solutions but they are worse for me * spreadsheets * vuejs works as compiled framework, but integrates everywhere - userscripts, jupyter notebook, app prototypes, etc etc
