I’d say hand-crafting pixel-perfect icons with different versions for extreme sizes is worthwhile (and I don’t believe in simple rasterization from vector for the same reason), but not every developer would have resources to spare for that.

I was lucky enough to oversee a project replacing seven hundred icons back in 2017, and we hand-adjusted the low resolution versions of 16x16 and 24x24. > “…notice that the icons are not simply the same image scaled up or down. TTrackBar is a good example of this: at each size, the small indicator marks are different. An icon designed for 16×16 or 32×32 won’t resize and scale to look good at 24×24, because the pixel…

I'm curious why the Bluetooth is required? Requiring WiFi makes (so the phone/computer is on a network and can communicate with the other devices), but what's the benefit of Bluetooth? Does it only work when the phone and computer are near each other?

Bluetooth is used to discover peers and to initiate communication. Thus handoff works even on a wifi network that blocks broadcasts. It even works when no wifi network is present, by setting up an ad hoc network for the connection. (Disclaimer: This is all I know. The details seem rather murky, as handoff is a proprietary Apple protocol.)

And I have one that unifies _both_ to `clip` so you can put the same command in both sides of the pipe, e. g. to turn a line-delimited blob on your clipboard to a space-separated one: clip | tr '\n' ' ' | clip https://github.com/svieira/dotfiles/blob/a3654d6a194e3689978... # Use clipboard in shell pipelines # clip | xargs echo # uses pbpaste # ps -A | grep search | clip # uses pbcopy clip() { [ -t 0 ] && pbpaste || p…

So to check if there's anything sitting on stdin without reading it I've been using `if read -r -t0; then` # returns true if there is data but times out instantly so it doesn't consume any Is `[ -t 0 ]` more idiomatic? Apparently it fails on this case: function `read -r -t0` is Bash-only though and not POSIX, but it will work regardless of what type of data is on stdin

Not a bad list of basic macOS specific cli tools. For a more in depth list, I usually reference https://ss64.com/osx/ .

A tad outdated. At a glance I see it’s missing `networkQuality` (introduced in Monterey) and `realpath` (added in Ventura).

`pbcopy` and `pbpaste` are one of my most-loved in the list. Dealing with some minified json, switching to iTerm, doing `pbpaste | json_pp | pbcopy` and having a clean output is _so_ nice.
