I am always looking for ways to improve my workflow, and therefore I am curious about new tools and approaches. This section reflects what I have settled on for the time being.
While I am not one of the "living in Emacs" types, I certainly have a good chunk of my computing life in Emacs. I use it as my programming editor, with lsp-mode taking care of integrating with various programming languages. It also holds my notes using org-mode and org-roam. My configuration is based on doom-emacs.
I have so far avoided bringing into Emacs things that I feel are outside the scope of an editor, such music playback (emms) or email (mu4e), although the work by Nicolas Rougier on nano-emacs and nano-mu4e, has been tempting me to change that position.
I have been using Linux for almost a decade now, and most of that time has been spent on Arch Linux. I loved the minimal base system, and how it would get me to experiment with my computing setup; I was always trying different window managers and writing little utility scripts to manage various things about my computer. This, however, was also the reason I moved away from it. I felt I was spending too much time experimenting with my setup and not enough time getting actual work done. When it came time to work on my Master's thesis, I realised that would be a problem. Switching to a curated environment like Fedora got me to stop tweaking my tools and actually use them instead — and I still have Emacs to scratch my tweaking itch with.
My language of choice for personal projects for the last few years has been Haskell, which I was using to develop Kima. Rust has been on my radar for a long time and I have been intrigued by its promise of combining modern language features with the performance of C/C++. I finally got around to using it for a project and I have to say it is everything I was hoping for. You get great performance writing "obvious" code, and there is a clear path for further optimising from there — as opposed to my experience with Haskell where optimising could mean starting at GHC Core. At the same time, it provides high level language features like traits, sum types (enums), and sane macros (unlike the C preprocessor). The combination sometimes makes the performance of the resulting executables seem like magic.
