I served as a kingdom herald when I was active in the Society for Creative Anachronism a few years ago. Learning blazon (the descriptive language of heraldry) was a lot of fun - the rigid syntax with its DRY goal of describing armory with as little repetition as possible reminded me somewhat learning a programming language.

LaunchBar[0], which predates Alfred but is similar in function, also has a fantastic searchable clipboard manager which includes a feature that I've not been able to find in any other clipboard manager: a push/pop stack.
With this feature you can, for example, copy a bunch of different items from a web page on to the stack, then paste them sequentially in a web form and pop them from the stack so that they're no longer in the clipboard history. With this workflow there's no hopping back and forth between pages, you do all of the copying at once in one place and all of the pasting at once in the other. It all happens via keyboard shortcuts, no interaction with the LaunchBar UI at all.
This feature is what's been keeping me on LaunchBar for almost 15 years now. Alfred looks great, but without this push/pop feature in the clipboard manager I'd have a hard time switching.
Their Emergent Task Planner kept me on track for years, and I still go back to it when I feel like my day is spiraling out of control. It's a great companion to my existing digital productivity tools.
From what I can tell this service will only check website certificates.
Can anyone recommend a similar service that doesn't have this limitation, ie one that can check certificates on SMTP, IMAP, and other protocols that aren't HTTPS?
Ah, very nice! Not sure it'll work, but you can specify any port for a website you want to check manually. See if https://www.haveibeenexpired.com/ssl/app.srsc.ru:8443 (replace the host name and port with what you need) works for you?
The automated monitoring (once you sign up and add domains/hosts) only checks HTTPS, so no dice there...
I really love the temporary installs feature of nix OS. Often I just want to try some software once and don't want to use it afterwards. The temporary install feature is perfect for that, to help avoiding building up bloat from forgotten uninstalls.
I think one thing that's interesting about "temporary" installation is that nix has this notion of "present" vs "installed."
When you run a nix-shell the program is downloaded and if necessary built and put into the nix store, after leaving the shell it's all right there on your disk ("present") just not "installed" into the environment.
This is why the first time you run nix-shell with something new it downloads stuff while subsequent invocations are immediate. It also means that if you liked ripgrep in a shell, installing it is just has nix write out some new symlinks.
