I updated "Jitsi Hacks" to work with the new Jitsi Meet user interface.

My brain: "Hey, instead of adding 5 lines to this pile of legacy code you could refactor it and finally create proper tests" – Three weeks of refactoring later. "See, that wasn't so bad. Now add your 5 lines over there. Don't bother testing them. That code is trivial." 🥴

@eighthave The Wikipedia page on the one in vienna mentions they planned the monument before even entering the city. Seems like making sure people don't forget who defeated the nazis was not an afterthought.

"Your E-Mail Validation Logic is Wrong"
https://www.netmeister.org/blog/email.html
Interesting read if you like email (address) trivia. Don't expect practical advice on how to do email address validation, though.

Hey guys, Thunderbird is STILL hiring developers. You can help modernize an application used by ~20,000,000 people and growing!
The open source community can make something better than Outlook, but only if folks come and build it.
So the answer depends on the context in which the address is used. SMTP servers that still support the obsolete parts of RFC 821 will accept \@@example.com as sender or recipient address. However, in the email's header the address has to be written as "@"@example.com, because \@@example.com is not permitted there.
The local part of an email address is allowed to consist of a single @ character. However, it must be encoded, e.g. as "@"@domain.example. RFC 821 (SMTP) allows using a backslash to escape a character even outside of quoted strings. RFC 822 (internet message format) explicitly states that this syntax is not permitted for the local part of an email address. All successor documents to these RFCs do not permit "backslash escaping" outside of a quoted string in the local part either.
@fedops I'm awarding 2 of 5 points for this answer.
@fedops Don't try this with K-9 Mail. It'll fall over faster than you can say oops 😉
@fedops I can confirm that some MTAs do funny things when confronted with "@"@example.com 😀
Quiz time: Is \@@domain.example a syntactically valid email address? Why (not)?

Recent developments, everywhere is dealt with and okay 👍
As you may or may not know, Tusky was temporarily removed from the Google Play store, and it has since been reinstated.
We will always appeal against any removals that we see as incorrect, or fix something that we view as fixable. If for some reason the app can't stay on the Play Store we won't stop the development just because of it, we'll find other ways to reach you.
Thank you for reaching out while that whole mess was going on. 🙏

After well over a decade of building the #AOSP at home, and building #Android firmware for a number of devices, I thought it was time to write up a few tips from things I've learnt about what makes a good AOSP firmware build machine. https://www.alsutton.blog/post/2021-aosp-build-machine/
Last week I finally got around to setting up my own #matrix server. It was surprisingly easy thanks to matrix-docker-ansible-deploy ❤️
