In case it might be useful to someone, here are the tools I’m using at the moment.
MacBook Pro + Magic Mouse + Magic Keyboard + BenQ GW2470HL monitor + Invision MX150 monitor arm + Omoton vertical stand.
My first choice for low-level research is Swift + Xcode Playgrounds. When I need higher-level abstractions I use Python + Jupyter Notebooks + TensorFlow.
Hugo + Skeleton + GitHub Pages.
Fork.
zsh + Oh My ZSH! + Powerlevel10k.
