The term "Newtype" more specifically describes a wrapper around a single type. It's like an alias. It's incorrect to describe an enum with two variants as a 'newtype'. I think the example was misunderstood from

> ADTs C++ is already a very complex beast as it is. ADTs (and pattern matching) make it concise to express many different programming things. But I'd imagine that adding it to C++ would be horrendous.

Well. Somehow (or for some reason), GIMP managed to get away with it. Though, the next crudest software name which comes to mind is "Git".

More generally, I'd think many/most mechanical keyboards are USB C. But I'd think that the budget, off-the-shelf keyboards would be USB A.

Elsewhere in the comments, someone said "I want dedicated keys for arrows / function keys, I use these frequently enough that I don't want to hold a modifier". Some programming languages type constants in UPPER_SNAKE_CAS

I liked the books emphasis on "interface" vs "implementation", and how this affects complexity. But one tidbit I did like from the book was along the lines of "if every use case involves the same action, it would be

I use an external keyboard, & haven't tried kmonad. I don't run into HRM even at over 100 wpm, on Dvorak. (I'd expect Dvorak to use home row more than qwerty), whereas one user in that thread said he needed to resort to a

There are tools like kmonad (and I think some others), although they do require a kernel extension (or driver extension). https://github.com/kmonad/kmonad/blob/master/doc/installatio...

I like putting the modifier keys (shift, ctrl, win, alt) underneath the home row keys using tap-hold functionality. (e.g. tapping 'f' outputs 'f', but holding 'f' acts as 'shift'). And Caps Lock'

I feel like Rust makes you pay a big cost upfront, and the benefits are often not worth that cost. It's easier to program if I don't have to worry about ownership/lifetimes. -- Garbage Collection allows not needing to worry a

I mainly use Evil mode on Emacs, but have switched to use Helix for when I need a terminal editor. It feels like the majority of Helix keybindings are the same as vim. Similar to how with vi-emulators, you'll bump into things you use t

This idea sounds nice. How big is your monitor? I just tried turning my monitor vertical. My initial impression is this left me with very little space with which to read text; and felt like it'd hurt my neck if I were to look up to the

Right. On Gnome, when I switch left/right between virtual workspaces, the animation provides some indication of the switch. When I tried xfce, there was no animation, it didn't feel like an improvement. Perhaps this is down to pre

Rust's enums are "sum types" or "tagged unions". Perhaps the most practical example of this is the Option type, where you can say an Optional value is either `Some(value)` or `Nothing`. With this, you don't hav
