As is often the case, the nix defaults for ls are spartan. I finally got around to wrestling my ls color settings into submission. On macos/zsh, gdircolors gave inconsistent results, so I set the LS_COLORS environment var directly.
brew install coreutils
if [[ "$(uname)" = "Darwin" ]]; then # macos uses a different 'ls' export CLICOLOR=1 source "$XDG_CONFIG_HOME/zsh/.dir_colors" alias l="gls -ahF --group-directories-first --color=always" else alias l="ls -ah --color --group-directories-first" fi

Just switched from rbenv to chruby using this guide, and my zsh startup time improved by about 10 seconds. I’d been meaning to debug why it was taking so long — bonus!
Here’s the offending lines that were removed from ~/.zlogin:
export PATH="$HOME/.rbenv/bin:$PATH" eval "$(rbenv init -)"
Internet-connected devices are increasingly supplied without a USB tethering option. While I presume this cuts down on manufacturing complexity and improves form factor, the wifi setup user experience is often terrible.
I recently acquired a FitBit Aria scale which has the completely undocumented quirk of only being able to connect to 802.11b wifi. My router defaults to n. I had to dig through the router settings and enable dual-band. There is absolutely no way a muggle would ever figure this out.
To compound the issue, their activation API was suffering a bug that returned a cryptic JSON error when using a Mac or iOS Safari to register the scales. I have no Wintel, so I finally got it working using iOS Chrome.
Googling revealed loads of posts by angry consumers who had returned the product as defective. I wonder how much this poor design choice cost FitBit’s bottom line? Omitting a USB setup option might have seemed clever but it backfired badly – perhaps it would have been fine if their wifi onboarding experience wasn’t so flawed.
And after enabling dual-band support on my router my Kindle Paperwhite would no longer connect to the wifi network. I had to manually enable WPS discovery mode on the router to pair it again. Oy!
