#hardwarehacking tip of the day: use a sharp blade for cutting through copper traces or end up with lifted traces & pads!

Is there still no cool, easy to install way to run a small local AI model that is "somewhat agentic" i.e. it can look up stuff online in its own little sandboxed web browser?

Use forums! Keep using #forums and #blogs! Most new content now happens behind closed doors of the social platforms and thus becomes way harder to find! I know it also gets crawled by AI, but that‘s another topic. :/

Unpopular opinion: moving to audio-only #smartglasses is NOT sufficiently privacy-friendly! In fact, in many situations, audio recordings may be more revealing than pictures. Also, audio requires less bandwidth, making stronger attacker models viable such as live streaming from hacked glasses...

It's a matter of time until it becomes unsustainable to let people use LLMs for free or for a fixed monthly (affordable) fee. Continue writing your own code everyone! Don't ever become dependent on AI for writing code (or anything else)!! www.wired.com/story/model-...

A security researcher using Claude Opus 4.7 found the AI tool could independently code an exploit to hack into Front Gate Tickets, the ticketing platform for almost every major US music festival from Lollapalooza to Bonnaroo. He could then issue any tickets at will. www.wired.com/story/claude...

I’ve always wondered, why can’t we run CPU’s hotter? 

Look at any modern CPU, and the maximum junction temperature (TJMax) is around 95ish C.

 Leakage current explodes past that point, and reliability drops off a cliff. But the question is…couldn’t you make a “tougher” transistor?
