One compromise that I can recommend is hosting the Email server yourself for incoming mail, but using an external SMTP relay such as SendGrid or SMTP2GO to send outgoing email. That way you never have to worry about your emails being blocked due to some misconfigured setting. Switching SMTP relay provider is easy so vendor lock-in is no issue.
Also, those services are mostly intended for broadcasting mass spam mails for better or worse, so for personal use their free tiers are almost too good to be true.
Here is my script gfm-preview [1], which I think is pretty cool since it implements a HTTP server in 50 lines of shell script (ab-)use with netcat.

The page will automatically update when the document changes using fswatch and HTTP long polling!
Spotify playlists are great but I would like to be able to shuffle from a combination of them. Playlist folders do not cut it because then all combinations must form a tree. So I made a shell script to create those combined playlists [1]!
I consider part of the blame to lie with React. The React source code structure is pretty obtuse. Compare that to the Inferno.js source code which is easy to understand and navigate for anyone familiar with how a VDOM library should work.
Gnome is also incredibly slow to allow one to select a particular window when Alt-Tabbing. It is a one second delay every time you want to change window.
In C89 is there a portable way to figure out the alignment requirement for a struct, to be able to, say, store it after the NUL terminator in the same allocation as a C string?
> you're going to hit some bumps if you haul an old code out of the vault and try to fire it up on a new system.
Most package managers have lockfiles that allow for some degree of determinism. Of course if a library introduces breaking changes you're going to have to rewrite, but only when explicitly upgrading the dependency.
