What it does
Diary 3 is a diary with AI chat that uses your entries to provide personalized insights
A daily journal that gives you one page for today, then preserves it exactly as it was.
Open diary3 and write the day you are actually in. Add a sentence, a note, a photo, or nothing at all. Past entries stay intact. You can read them, search them, and trust that you are not editing the memory after the fact. Create a short-lived markdown link and paste it into ChatGPT, Claude, or Gemini. The link expires when you say. Set the day boundary that matches your life. Export everything whenever you want. Delete the account when you are done. Start with text for free. Upgrade only if your diary gets media-heavy. Because it already happened. Today is the only page you can change. The day stays blank. You don't get to rewrite it later — the gap is part of the record. Yes. Anytime,…from diary3.com

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
