LLM.txt feels DOA indeed, we opted to serve it as the root for elastic.co/docs for text/plain and text/markdown to increase its usefulness.

Most coding agents websearches will do a rudimentary conversion of html to markdown though to preserve context. So the need becomes less unless you want to steer the markdown it sees without loss.

While very true for crawlers, coding agents websearch() do use content negotiation. So still very useful, the elastic.co docs render LLM specific markdown not just the raw sources. It's a chance for us to inject or condense context.

Pushed out Mermaider, render Mermaid diagrams to SVG in pure .NET.

Not just a DSL builder or browser wrapper, this is the full stack: parser, layout engine, and SVG renderer. No JS, no child processes.

Lightweight Sugiyama layout engine included. AOT-ready.

Love this! Looking forward playing around with it. From the mastadon post it sounds like its powered by a reactive/observable model? Will it use IObservable to call Func<Visual> ?

Submitted 2 security issues to NuGet and GitHub last year, finally heard back that they are low priority and not a big deal.

I did manage to publish this package to NuGet. A bunch of unicode in there, but it looks genuine, right? Nobody would discover this via search because of the unicode.

This is a disappointing response @nuget.org @blowdart.me not too late to harden the checks here. If only to harden your reserved namespace prefix checks.

Testing a Fresh Look for JetBrains IDEs | The JetBrains Platform Blog Visual context is always changing – and so should the look and feel of the tools you use every day. We know how much a familiar UI matters, and we’ve heard your feedback from past updates. That’s why

I'm loving this visual refresh for the JetBrains IDEs. I've been using it for a week or two already, and I'm a big fan of Many Islands, especially in dark mode. No functional or structural changes, just a nice, clean visual update. What do you think?
