I fine-tuned a Llama model on my own notes to build a chatbot that mimics my voice — and discovered that AI is less magic and more data pipeline than I expected.

Round four. Same rules as May and June: dig up what tech leaders said about AI in a given month, hold it against what actually happened. 🍷 aged like wine, 🥛 aged like milk, 🤷 jury’s still out.…

Every year I dread coming back from vacation not because of the work, but because I have no idea where I left off. A failing test, a well-written TODO, and a slow first day back are all you need to…

Books and some interesting pages I read in June 2026 This month I decided to not finish a book after reading the first 100 pages, so I just finished a single book. The warm weather and outdoor…

A number that sat still for most of my life just moved: the 1099 threshold jumped from $600 to $2,000 for 2026, and almost no one noticed. What changed, the timing that trips people up, and the catch…
