A Second AI Security Body in a Fortnight. This One Caps Membership at Fifty.

The AI Trust and Security Consortium launched on 11 August with fifty seats and incidents shared under strict confidentiality - the opposite principle to SAFE, which publishes a taxonomy anyone can use. Neither has enforcement, and the frontier labs are absent from both.

A Reporting Standard for Rogue AI Agents, Minus the Two Labs That Matter Most

Over 120 organisations have proposed SAFE, a common taxonomy and clock for reporting AI agent security incidents. It borrows aviation's model but has neither of the two things that make aviation reporting work - and OpenAI and Anthropic are not members.

Mozilla Revoked a Signing Key Nobody Stole. That Is the Correct Answer.

An unencrypted copy of the Firefox release-signing subkey was committed to a private repo. No evidence of misuse, everyone with access already held the key — and Mozilla rotated it anyway.

Can a Deleted File Be Recovered? We Erased the Whole Volume and Read It Back

We wrote a file marked so it could not be mistaken for anything else, deleted it, then erased the entire volume the way Disk Utility does — and every one of the 4,500 markers was still in the raw bytes on all three filesystems, with the sentence inside the file readable word for word. One volume came back empty, and it was empty before the delete.

Latency vs Bandwidth: Which One Are You Actually Waiting For?

Internet plans are sold in one number, and for most of what you do all day it is the smaller half of the answer. Asking one host for six payload sizes separates the two: a fixed cost of 218.6 ms and a throughput of 116.5 Mbps, both out of the same measurement. Ten thousand times the data cost 4.9 times the time.

Why Is My PDF So Big? It Is Probably a Picture of Text

We built one A4 page both ways and weighed them. As text: 8,256 bytes, with 4,791 searchable characters. The same page scanned at 200 dpi: up to 703,029 bytes, of which 99.5 per cent is the image, and zero characters extractable. The surprise is that storing the scan losslessly beat every JPEG we tried.

Why Is My Disk Full? Every Tool Is Answering a Different Question

The same 494 GB drive reports 6 per cent used, 53 per cent used and 56.3 per cent used depending on what you ask — and all three are correct. Measured on one machine: the volume most people check is the sealed system you cannot write to, 2.7 GB sits on no volume at all, and one file claims to be 494.4 GB while occupying 73.1.

Claude Code Stops Asking on Friday. Its Own Study Says Humans Caught 13.6%

From 14 August the approval prompt in Claude Code is off by default for Pro, Max and Team accounts. Anthropic says people caught 13.6% of dangerous commands, and its classifier 89%. We measured the same control on Sunday and got a very different number.

How to Take a Screenshot (and Not Ruin It Afterwards)

The keystroke is the easy part. What you have made is a PNG, often several megabytes, and almost every piece of advice about shrinking it is advice about photographs. Measured on two samples: JPEG at quality 90 came out 1.45 times the size of the PNG and still damaged the text, while lossless WebP was 0.35 times the PNG with nothing lost at all.

How to Remove the Background from an Image

There are two methods and almost every article pretends there is one. A flood fill removes what matches the background and touches the frame edge; a neural segmenter guesses which pixels are the subject. The fill is exact when the backdrop is plain AND the subject is a different colour from it — measured here at 105,600 pixels out of exactly 105,600. Miss the second condition and it deletes your subject too, which is what happened to a real studio photograph tested for this guide.
