How fast is N tokens per second really?
Every local-LLM benchmark reports throughput: "47 tok/s on an M3," "180 tok/s on a 4090," "500 tok/s on Groq." Unless you've actually watched tokens stream at those rates, the numbers are hard to internalize. This is the rendering.

The Eternal Sloptember
I’m calling it now, the adoption of AI agents into software development will be one of the most costly mistakes in the field’s history. Agents cannot program, and it’s taking longer and longer to realize that they can’t. They are a highly sophisticated statistical model designed to mimic the distribution of…

I don't care how well your "AI" works
The other day I was sitting on the doorstep of a hackerspace, eating a falafel sandwich while listening to the conversation inside. The topic shifted to the use of “AI” for everyday tasks, people casually started elaborating on how they use “chat assistants” to let them write pieces of code or annoying emails. The…
