Anders Hejlsberg (@ahejlsberg) is a living legend: he created Turbo Pascal, Delphi, C# and TypeScript (and today TypeScript is the most-used programming language, globally, as per GitHub.)

@turbopuffer – a vector and full-text search engine built on object storage. It’s fast, cheap, and extremely scalable. https://t.co/w9y67GsFZJ

Four things that stood out to me:

1. “10x better for 1/10th of the price” is a proven winner.

This is what Turbo Pascal did: it sold for $49.95 when competing compilers cost $500, and it was faster and more interactive than competitors’ products. Conveniently, the low price tag also killed off piracy

2. C# might have not existed without a famous court case.

Microsoft originally hired Anders to architect its Java tools (Visual J++), but the Sun versus Microsoft lawsuit (1997-2001) meant Microsoft could not build on top of Java, as the company that owned Java’s IP (Sun) sued MS for alleged unauthorized changes to the Java language. Microsoft realized it had to build a new language that combined VB’s productivity with C++’s power. This led to C# and .NET.

3. TypeScript exists because Anders refused to build Script# for the Outlook .com team.

Microsoft’s Outlook .com team asked Anders’ C# team to productize “ScriptSharp,” a language to cross-compile C# to JavaScript. Anders and the C# team pushed back, suggesting that a better approach was to fix JavaScript. Anders felt strongly that to be attractive to the best-of-breed developers in the JavaScript ecosystem, you want people to write JavaScript, and not another language like C#.

4. Designing a programming language is a 10-year play.

As Anders puts it: “Version one is great, but has all sorts of issues. You’ve got to do version two, but it’s not until version three that it really starts to be great. Then you’ve got to convince people to adopt it.”

Avalonia 12 support was added to Mapsui 5.1.0-beta.7 🎉We had quite some requests for this.

Can I have some cheers from the Avalonia community?

Big thanks to everyone who reported this and helped debug — especially in issues. 🙏

🗺️ Mapsui 5.1.0-beta.6 fixes rendering of Chinese, Arabic, Japanese, Korean and other non-Latin scripts in labels, callouts, and widgets. No more □□□ boxes! Here's how 🧵

[Mapsui @Mapsui]

Root cause: SkiaSharp's default font has no glyphs for CJK, Arabic, Devanagari, etc. — characters appeared as empty boxes ("tofu"). It's how system font resolution works under Skia, not a Mapsui bug per se.

[Mapsui @Mapsui]

Fix: Font.FontSource - point it at a font file that covers your script.
FontSource = "file:///fonts/NotoSansSC.ttf"
Works for LabelStyle, CalloutStyle, and now Widgets too.
Tip: Google's Noto fonts cover virtually every script. https://t.co/JOvJWfazSq
Requires experimental mode.

Making TextBlock measure 333x times faster (yes its 33x times faster) in Avalonia thanks to PretextSharp

[Bert Temme @berttemme]

Built a static transit app for the Netherlands — 52,000+ stops, all operators, no backend. Because all other planners are pure shit 💩

I love how "being written in rust" is now part of the selling point of many dev tools... 🙃🙃🙃

Me: Do this thing
AI: This is a massive task
Me: Yeah, do it
AI: It’s truly massive and requires editing 205 files
Me: Yeah, Microsoft is 10x’ing their price. Now get to work!

[Simon Willison @simonw]

Is there still a widespread belief that LLMs and coding agents are good for greenfield development but don't help for maintaining large existing codebases?

I don't think that idea holds up any more
