I've gotten into golang and rust to a certain extent, while I still do hack on typescript stuff all the time.
Latest - 2021
I use nvim, tmux and a bunch of servers off vultr/hetzner to run experiments and etl jobs.
- Made the move to golang around late 2020 and its paying off in multiples rn (April 2020)
- Working with a lot of core eth stuff - assmebly, custom contracts, trying to automate complex things on-chain (deleveraging, DSProxy, create2 etc)
- Slowly dipping my toes into things directly related to eth - kademlia, distributed peer tables, devp2p. This is super underexplored.
- Learn't the importance of looking at the yellowpaper so I don't get half assed answers elsewhere (wtf bro you said etherium is the future)
- Pipelining and data infrastructure is critical, even more so when it comes to crypto. Probably the single most important thing top of mind for me rn.
- I usually roll my own infra (either kube or docker compose) on servers. Build and run nodes from source so I can mod them easily.
- Turned my old CS:GO rig into a linux box, running i3 on there ocassionally
- SpaceVim and Neovim save my life, and sanity.
- Alacritty is a much faster, GPU backed terminal written in rust. Start using it. Now.
