actually a lot of people don’t know this—if a cop demands to know whether your parser uses a context-free or context-sensitive grammar, you do NOT have to answer.
thinking about writing a parser from scratch. It’s not illegal. If a cop asks you “are you writing a parser from scratch” and you say “yes” they still can’t do shit.

You know I’m a Food Guy, and Paprika is where all my recipes live. It’s a no-nonsense, pragmatic, workhorse kitchen app. If you know what a mise is, this is the recipe app you want.
The single most useful cooking app I use, Paprika, is on its annual sale
You give it links and it pulls and formats the recipe for you so you can save it and look at it in the future without ads or long narratives
I use it on my phone, so here’s the link apps.apple.com/us/app/papri...

If you installed the Visual Studio 2026 preview and were getting lots of errors trying edit C# code…sorry about that. We shipped a fix an hour ago so go check for updates in your Visual Studio Installer.

Hey so Visual Studio 2026 Insiders is out, and it's very exciting, but if you edit Razor files I have a personal favour to ask. For the last ~18 months I, and a few of my friends, have been working on a new foundation for the Razor editor called "Cohosting". I'd love for you to try it out.
