Tell me you didn't watch my talk without telling me you didn't watch my talk. https://www.theregister.com/columnists/2026/08/03/claude-code-is-revolutionizing-digital-archaeology-enterprise-better-dig-it/5281676 - I never said I designed the Transputer accelerator, I built it from parts I got from the guy who designed it in the 80s. - I said I used Claude because I ran out of time and the code wasn't working. All but one of the fixes on the RISC OS side were human-done... and I sti...

I'm thinking about doing #40c3 - are any mutuals in a position to share a voucher code with me when they land? Went for 33c3 and missed it ever since. #ccc #c3

Speaking of the Sinclair C5 - I hear it has a ULA to control the battery logic. Anyone know where I can get my hands on a dead ULA to decap? I have a wild idea which might lead to a like-for-like ULA replacement. (boosts appreciated)

I wish whoever organised the #emf2026 #emfcamp Elon Burning had given about fifteen or twenty minutes notice... Five wasn't quite long enough to get myself and a friend with mobility issues to the lakeside to watch ;( (Also pls use a human voice for your wardials, I thought someone was pratting around with the phones...)

Engaged with the "process" as asked, and all I've got is demands and a demand that I "guess what the problem is" and "offer any information you think might help explain". I feel like I'm in a non-consensual re-enactment of Kafka's "The Trial". If you don't tell people what they've done wrong, how can they learn and improve? How can there be any trust? Honestly really just - don't know how to feel about #emfcamp #emf2026 right now...

EMF says everyone should feel comfortable attending. That depends on trust in organisers’ judgement. EMF's Villages organiser says a group they’re part of can “bypass the CFP”, jokes about having a “vested interest”, then jokes about someone accused of serious animal abuse. On top of everything else - I don't know what to think or how to feel about this. Context (CW animal abuse): https://dogpatch.press/2025/10/23/uk-furry-zoosadist/ Public chat; unrelated names and avatars redacted.

I got tired of debugging SIP fax lines manually and annoying Marrold with dumb questions and my own stupidity. So I made this. It receives a fax, analyses the data and audio from it, and looks for common flamingo-ups like G711 alaw and ulaw mismatches or lossy resamplers. It can also detect failures in T.38->G.711 fallback and report that. Bonus: it tells you what your fax machine can do. And then it sends you a fax back with the result. And instruments that too!

Had my website taken down by a bunch of asshole AI bots sitting behind Alibaba Cloud and running what was effectively a DDoS. I've blocked both their ASNs as a result. If you were doing something legitimate with my content, please get in touch and I'll add an exception rule.

This quote keeps popping into my head unannounced... Crowley: "What was it he said that got everyone so upset?" Aziraphale: "'Be kind to each other.'" Crowley: "Oh yeah. That'll do it."

How it started, how it went and how it's going. First time I've ever mixed mortar or laid bricks. I guess I'll find out how good a job I did next week sometime?

Well, today I learned about https://cppinsights.io/ and as cool as it is, the demo code with the range expression over an array makes me think "I can see why that works but I wouldn't have written it that way".

Librarians of a certain vintage, are any of you aware of a surviving copy of the BLCMP (Birmingham Libraries Co-operative Mechanisation Project) library automation software? It existed in the 1980s and 1990s before being replaced with other systems like Talis or Dynix. I&#39;d love to see it running again! (also see vga256&#39;s post looking for a copy of Dynix ILS - https://dialup.cafe/@vga256/113822702847532196) #libraries #digipres
