@RyanRodemoyer2 I think I’m leaning towards: ”Some warnings as errors”, basically using editorconfig to up the severity to error where it make sense.

Ever since .NET Framework 3 was released, whenever I see a changelog of the .NET versions, I try to understand what "CardSpace" was.

To this day, I still don't get it.

We are alarmed by reports that Germany is on the verge of a catastrophic about-face, reversing its longstanding and principled opposition to the EU’s Chat Control proposal which, if passed, could spell the end of the right to privacy in Europe.

@shahidux Lots of reading to do 😀 Looks great!

Chat Control är åter på bordet i EU. Regeringen säger åter ja till att förbjuda helkrypterade tjänster.

Frågade i torsdags försvarsministern om Chat Control ökar eller minskar vår förmåga att försvara Sverige?

Svaret blev att försvaret inte använder Chat Control.

Va? Men? Hur?!

No disrespect to Linus Torvalds, but this guy is the greatest geek alive 🫡

Created UNIX in 1971 when he was 28 years old.
Created Go in 2009 when he was 66 years old.

He also developed the B programming language (which led to C), created UTF-8 encoding (making international text possible online), and designed essential tools like grep that developers still rely on daily.

He also helped with the development of Multics (that led to UNIX), Plan 9 from Bell Labs and Inferno operating systems.

That's 4 operating systems in total... Most people don't even use these many OS.

Pretty impressive resume, right?

And it's a shame that many people, even the ones in the IT and tech industry, don't know him.

Ken Thompson.... Remember the name 🙏

🇬🇧Public pressure works: Belgium, Finland & Czechia will NOT approve the #ChatControl mass surveillance law in October. But other governments whose vote is crucial are still on the fence. Urge them to protect our digital privacy and encryption now: https://t.co/I5NJcJAHR8
