AI did this β€” Yohan Lasorsa Inaugural blog post β€” thoughts on finally having my own space, and how AI coding agents changed everything.

After 18 years without a personal website (last one was from my student days πŸ˜…), I finally have my own corner of the internet. Blog, projects, all built in 2 days with AI coding agents, without writing a single line of code. First blog: thoughts on this shift.

Spec-driven development with AI: Get started with a new open source toolkit Developers can use their AI tool of choice for spec-driven development with this open source toolkit.

Spec Kit shifts workflows from code-first to intent-first: an evolving spec drives plan, tasks, implementation so agents (Copilot, Claude, Gemini) stay aligned. Clear checkpoints, less guesswork. Worth a read: github.blog/ai-and-ml/ge...

Screenshot of a GitHub Codespaces VS Code interface showing a README.md file for codespaces-llm repository. The file describes a GitHub Codespaces environment with LLM, Python 3.13, uv and the GitHub Copilot VS Code extension. It has a "Launch Codespace" button. Below shows a terminal tab with the command "llm 'Fun facts about pelicans'" which has generated output listing 5 pelican facts: 1. **Huge Beaks:** about their enormous beaks and throat pouches for scooping fish and water, some over a foot long; 2. **Fishing Technique:** about working together to herd fish into shallow water; 3. **Great Fliers:** about being strong fliers that migrate great distances and soar on thermals; 4. **Buoyant Bodies:** about having air sacs beneath skin and bones making them extra buoyant; 5. **Dive Bombing:** about Brown Pelicans diving dramatically from air into water to catch fish.

GitHub Codespaces provides a free web-based development environment backed by a Linux container... and it turns out it also includes a GITHUB_TOKEN environment variable that provides free API access to the GitHub Models collection of LLMs
