I feel it should just roll over after 9,999. On a more serious note why is unread uppercase on iOS and lowercase on macOS? Was there HIG guidance on this at one time?

This country's obsession with eggs cracks me up. At this point I 💯 prefer a tofu scramble over eggs, and flax eggs for cooking. Tofu is tastier, healthier, cheaper, safer (UTIs, bird flu), more worker friendly, more environmentally friendly, and less cruel. #wfpb #vegan #tofu
Here's the complete nutritional comparison between eggs and tofu

otool is an easy way to see what frameworks an app is using. Here we list all the shared libraries, and then pipe the output through grep.

I'm really liking my new Mail.app configuration. I drag action items into Reminders.app and archive so I don't typically need the sidebar. I've used it for so long I know most of the keyboard shortcuts. The only issue with this set up is having to show the toolbar prior to searching. #macOS

The ping time difference is random, otherwise the new travel router is much faster on the same connection. Now we just need a better internet provider.
