Since Claude is down we probably can see a traffic spike on Pornhub for all the vibe coders.

Nice one! Just checked out your website... out of curiosity: What kind of music are you DJing?

Apple has a private CSS property to add Liquid Glass effects to web content I have an incredibly boring summer hobby: looking at the changelog for the WebKit Github repo. Why? Because I spend a chunk of my professional life working with webviews inside mobile apps and I like ...

TL;DR Even Appe is so lazy that they're using Webviews in their apps for displaying liquid glass - but you can't:

Appleโ€™s new Liquid Glass: stylish effect with fluid animations - reviving early-2000s Aqua vibes. Critics see issues: accessibility, wasted GPU power, and nostalgia instead of innovation. Apple's goal? Reinforce native apps over web. But real fix needed is App Store economics, not just UI tweaks.

Mistral launched Magistral, a reasoning model. Glad to see a european model provider. A bit sad that only the small one is open weight and that it's lagging far behind Deepseek. The medium one is quite good.

OpenAI released Codex; Iโ€™ve been underwhelmed by Sonnet lately: I asked an agent to implement Rails/Turbo drag-and-drop, but it produced subpar code with a nasty page reload instead of Hotwire. Only step-by-step instructions yielded an acceptable solution. Let's see how it measures up to Codex.

AI Blindspots Blindspots in LLMs Iโ€™ve noticed while AI coding. Sonnet family emphasis. Maybe I will eventually suggest Cursor rules for these problems.

To all the vibe coders out there. A nice compilations of blindspots that an AI has while developing software:

Mistral OCR | Mistral AI Introducing the worldโ€™s best document understanding API.

I've dabbled with a lot of vision models (ChatGPT Vision, LLAMA Vision) to replace our OCR chain (Google Document Cloud and then an LLM to clean and process). Unfortunately they were hallucinating too much or gave suboptimal results.

Mistral OCR looks really promising:

Package Version MCP Server - For AI Tools Help AI tools like Cursor to automatically use the correct package versions when adding dependencies to your projects. Supports Hex, RubyGems, and NPM packages.

Yesterday, I released a tiny MCP server that allows Cursor Editor to get up-to-date version information for external Hex dependencies. Someone suggested doing a version for #RubyOnRails, so I built a more generic version that supports Ruby Gems, Hex, PyPI, and NPM.

I'm trying to do importmap only. But it's really hard. Especially when you need some js at build time.
