My preferred language at the moment is Rust, which I'm still exploring the use cases of. So far it's proving to be a very adequate replacement for C and C++, although I need more practice to fully grasp the semantics of it and how it works internally.
My other languages are C++, C, Python, TS/JS with React, Java, and F#, in order of experience.
The C and C++ go somewhat hand-in-hand (although they're definitely not the same language). I use C++ where I can because RAII is wonderful for memory management, as well as the fact that the STL exists, but sometimes C is unavoidable. I'm a better C++ programmer than a C programmer.
TypeScript and React I've used in a professional capacity, and I enjoy the simplicity of them.
Python I find incredibly useful for quick scripting, prototyping, and other automations
Java is fine. Just fine. It works, the ecosystem is very mature, and it's hard to mess up other than in the performance department.
F# I use profesionally, and is generally very nice to use once you get your head around thinking functionally (learning Rust first helped with that transition)
Other Cool Technologies
I use Powershell a lot for automating simple processes or creating basic command-line "applications". The fact that it's basically just a C# interpreter makes it extremely easy to use but quite powerful
I'm currently having a look into Docker and Containerisation, as I want to learn more about microservices and how they can be leveraged in practical contexts. Kubernetes will probably be where I go next if this research looks promising
I primarily use Arch Linux on my personal machines, although I'm also pretty good with Debian/Ubuntu and RHEL
Extra Facts
Currently I'm working on an MMORPG in Rust as a learning exercise, which may at some point become a public repository
My favourite colour changes far too often for me to reliably put it here, but if I had to hazard a guess it would be ~#4f424f.
My favourite colour of paint is Valspar's Sleepy Kitten in Matte with 4000K lighting, which I'd strongly recommend getting the Premium Walls & Ceilings version of because you'll get away with only two coats as opposed to the Classic which can take more than three.
