Refix: Fast, Debuggable, Reproducible Builds

What makes it really fast is a small Rust program called refix that post-processes your build outputs (if you don't want to compile from source, here's a static Linux binary .)

Receive push notifications from your rice cooker

I have a lovely, and reasonably priced, Mini Panda Rice Cooker. It does not have any SmartHome features. You put in water and rice, press a button, it cooks rice. Nice!

Why Vim uses hjkl keys as arrow keys

I was reading about vim the other day and found out why it used `hjkl` keys as arrow keys. When Bill Joy created the vi text editor he used the ADM-3A terminal, which had the arrows on hjkl keys. Naturally he reused the same keys and the rest is history. Here is how the `hjkl` keys looked. ADM-3A keyboard's hjkl…
