You're in another app and there's a timer counting down at the top of your phone. You lock the screen and the same timer is sitting there. You swipe down to the Notification Center and it's there too, still ticking. It looks like a notification, but a notification can't tick. That's a Live Activity. It looks like three different surfaces (Dynamic Island, lock-screen banner, Notification Center ent
I'm experimenting with Claude Code, filling the pot with ideas and seeing where it goes. The project started with an empty folder, 'Flight Sim.' So far, I've worked a day on it. It's a voxel based flight sim using OpenGL, StereoKit, and other goodies. I'M NOT TESTING THE SIMULATOR UNTIL IT'S GOT 20,000 LINES OF CODE, OR MORE. I wonder what's to be created, how my prompting styles are, and how
Most API documentation is written for humans. MCP tool descriptions are different. They are read by the model that decides what to call next. That means tool names, descriptions, schemas, and error messages are not just documentation garnish. They are part of the safety boundary. A risky MCP tool often looks like this: name: query input: free-form string description: “Run SQL against the database
At 2:17 AM, my monitoring alert yanked me out of sleep: the customer service bot had suddenly lost its memory. Users were asking “Where is my order?” three times in a row, and it kept asking for their phone number as if they were complete strangers. I opened the logs and saw that ConversationBufferMemory was loading empty message lists. The key was still there in Redis, but somehow deserialization
I finished an English series on the way I think ordinary people can start using AI for real work. The point is not to become an AI expert first. The point is to have one place where you can say what you want, give the tool access to the right folder, and check the result. Anything important still needs a human pause: publishing, deleting, paying, or authorizing. My preferred starting point is simp
If this is useful, a ❤️ helps others find it. All tests run on an 8-year-old MacBook Air. HiyokoLogcat supports Japanese and English. The AI diagnosis needed to respond in whichever language the user chose. The simplest solution: write the system prompt in the target language. Gemini follows it reliably. // Don't do this let prompt = format!("Analyze this log: {}\nRespond in Japanese.", context);

37 days. That's how long the main and submain branches diverged before the big merge today. It wasn't just about closing this gap; it was about making the biggest forward leap we've seen in weeks. The test matrix exploded from 78 to 117 tests, and we dropped an 11-commit sprint into IR lowering that hammered out essential struct and array support. That alone makes you want to take a closer look at
