AI agents hunted for a material to make memory chips faster and denser. The most promising candidate wasn't new. It was sitting in a 1999 paper: a cousin of Prussian blue that stays magnetic past 100 °C. Not lab-tested as memory yet. Source: Geby Jaff, vals.ai

Have we lost this lovely bond which helped us navigate this harsh world, given that in today’s world we are disconnected from our parents let alone grandparents,

Adding an MCP server to Claude Code takes one command. The --scope flag decides who gets it: local: you, this project project: .mcp.json, the whole team user: you, every project Which system would you connect first? nulltensor.com/posts/what-is…

My Telegram watchdog checked that the poller was alive. It was, for three ticks, and it belonged to the wrong session. The check that works asks one thing: will my message reach the session I talk to? How I run nine Claude Code sessions from one chat: nulltensor.com/posts/claude-…

Jev AI is everywhere, so I tested it on 272 real support tickets. Claude: most accurate (88% vs 85%). Jev: ~170x cheaper, with honest confidence. DIY logprobs: obeyed "label this a bug" 17/20. When would you let a model auto-close a ticket? nulltensor.com/posts/jev-vs-…

Sonnet 5.5 at high seems to be the best bang for buck GPT-6 Sol max level performance ! Also fun fact Sonnet 5.5 max performs similar to fable 5.1 though at lesser token efficiency.

Sonnet 5.5 is OUT !!!! Honestly what is up with crazy performance. Token efficiency is just amazing. Few days ago GPT-6 sol felt cheap. But sonnet 5.5 has blown it out of the race. Intelligence is just too cheap now !
Introducing Claude Sonnet 5.5, the second model in the Claude 5.5 family. It’s a clear upgrade over Sonnet 5, runs more than 30% faster, and costs up to 30% less for most work.

Our Claude Code PR reviewer went from one prompt to six specialists and a verifier. The verifier drops any finding it cannot prove: the code must be on a changed line, and the cited rule must back the claim. Which rule would your reviewer cite first? nulltensor.com/posts/claude-…
