The database app in LibreOffice, based on the Firebird database engine, can do all that.

I use Brevo as well. Free tier: 300 emails per day.

Very happy with them.

My wife pointed out to me a couple of years ago that I was simultaneously the oldest person on our Dev team, and the youngest person in our church.

I see that Focalboard stopped reviewing or merging pull requests since last September, though.

Back in the 1980s, before MS Word was the unquestioned king of the desktop, there was a DOS word processing program called WordPerfect. Everyone used it.

WP had a feature where you could press a special key combination and the screen would split. The top would have your text (not WYSIWYG, that was way in the future, although WP could show an approximation).

In the bottom part you could see your text, along with every control coffee code that turned bolding in or off, marked text for a table of content, etc.

Not only could you see it, you could navigate through it and delete codes, or watch the codes change as you edited text in the to half of the screen.

It gave you a control that I still miss these days. No more wondering why your word processor is doing columns wrong, or why the image you inserted doesn’t line up properly.

Check it out (starting at around 4:20).

Oh, to have “reveal codes” like WordPerfect!

I used to use Rainlendar. Not FOSS but the lite version is free.

In the Pulitzer prize-winning book “The Soul of a New Machine”, Tracy Kidder writes about a microcode programmer having to deal with timing in nanoseconds. One day his desk was empty and there was a note on the monitor saying that he was going to live in a commune, and no longer deal with any duration shorter than a season.

It could be that this is a habit left over from pascal, where result is a reserved word, and is automatically made the return value of the function.

If it is in the context of a short function, I don’t see that it’s all that bad.

I am a big fan of MyNoise, which mixes real-life recorded sounds, but you have a ridiculous amount of control over almost everything.

It’s browser-based, so compatible with any device. Once it has downloaded the sounds, it doesn’t use any more bandwidth.

Definitely worth supporting with a donation.
