AI & GPU compute
A November 2026 price snapshot grades 25 cards on dollars per gigabyte and dollars per token per second. The AMD Instinct MI50 and a used RTX 3060 take S tier, the RTX 5080 lands in F, and memory decides almost every grade.

Founder Briony Kennedy says a website migration cut sales by about 30% and broke roughly $1 million a year in ads. Adobe will not comment. The $150 million Adobe settlement in the headlines concerns consumer subscriptions and has no stated link to her contract.
Linux & open source
A progress bar that timed the copy into memory, while the stick lagged far behind, corrupted files for anyone who trusted it and pulled the stick. The fix took 4 merge requests and a Linux call so sharp its own manual calls it extremely dangerous.
Security
A permission shortcut saves the exact command you approved, password included, into a project file that often gets committed. The bigger lesson is that AI coding agents have created new places for secrets to hide, and the usual scanners are not looking there.
Security
An AI pipeline found, proved and drafted fixes for 948 kernel bugs at about $1,279 each. Finding them was the cheap part. The bigger lesson is who now has to fix them, and how fast.
AI & GPU compute
MIT researchers had GPT-6 Astra edit 0.016% of a small model’s weights, with no training, and its math score jumped from 7.9% to 48.1%. The number is real and the method is strange. The limit they found in the same paper is the part worth understanding.
Security
Playwright bundles its own Chromium that lags Chrome stable, and it launches with the sandbox off by default. For a human running tests that is a small risk. For an AI coding agent browsing the open web on your laptop, it is a bigger one. The fix takes 2 settings.

nvidia-smi tells you the card is busy. It does not tell you the card is working. I want to show you the gap between those 2 things, because closing it is often one number you type in Python.

There is a specific moment happening in AI pricing right now that is worth understanding clearly, because it is the first real signal of how the economics of this entire industry are likely to shift over the next few years.
