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 still had to figure out by hand why the slop Occam was inefficient.

sigh...

This is the most musical "the number you have dialled is not currently in service" intercept message I've ever heard - does anyone know where it's from? (boosts appreciated) #voip #asterisk

Hell is this.

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)

@isleofmandan@mstdn.social @Richard_Littler@mastodon.social I've been saying we've got about five years left for the last thirty...! I guess if you backdate it...

I've also added a tutorial on how to block internet abusers by AS number - YMMV. Also bear in mind this is a very blunt tool and really only viable for situations where it's appropriate. Think very carefully before you use it. https://www.philpem.me.uk/computer/block-by-asn

Anyone know what the melting point of a pair of Crocs is? Because mine have, and nothing else in the tent has been affected... #emfcamp

"Man from Barking said 'Aruf' to his dog, corresponding Welsh CW station slowed down."

@StripeyYena@chaosfurs.social Orphan sources? Are you going to #emfcamp too?

Hmm. I'm sure that'll buff out.

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

@nichni@mastodonapp.uk @lina@ohai.social And then you find out the Turtles were named after the Renaissance masters!

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...)

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?

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. Anyone else having issues?

@uvok@woof.tech there's a few of us around! my partner is in embedded stuff too

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.

@emf@social.emfcamp.org 🎉 🎉 🎉 🎉 heck yes. I just shared this with a few friends who were over the moon about this

@tilton@fursuits.online @TechTangents@dialup.space If you have to bot the comments to build up support for your idea, it's a bad idea...

@arktronic@infosec.exchange fair play, but the "human" is blindly accepting what copilot says, and offering nothing of their own.

@me_@sueden.social Thanks - but a friend would like to know about the exact circuitry in the ULA, document it, and try to model it. AIUI there are some things about the AVR one they'd like to change or improve.

@foone@digipres.club @dec_hl@mastodon.social @gloriouscow@oldbytes.space @polpo@chaos.social I was just typing "you're going to make it run Doom, aren't you, and you're going to send keyboard data with ATAPI commands"

@gloriouscow@oldbytes.space @foone@digipres.club @dec_hl@mastodon.social @polpo@chaos.social has anyone done a source-recreation of Catz, Dogz or Oddballz? Because someone should. Just so we can have that.

Did this get posted on hackaday or something?

@nina_kali_nina@tech.lgbt @domi@donotsta.re @vga256@mastodon.tomodori.net I'm too busy writing archiving tools but I'd love to see this. Was it Outernet who transmitted part of Wikipedia on satellite for a while? That page set would probably be a great starting point.

@uriel@bbs.keinpfusch.net An ActivityPub jobs (wanted/offered) board could be pretty interesting. No idea how it'd work in practice.

@fsphil@mastodon.social Oh no, not this again.......

@kieran@hom.ph @evi@meow.social yeah I can - I mean I got "a" remote for your collar. "ID 12345", heck, same as I have on my luggage!

@fsphil@mastodon.social Mine's in need of the same mod. 15,000 BTU and still only knocks a few degrees off the room temperature.

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".

@vga256@mastodon.tomodori.net It was actually preserved by @david_rysk@mastodon.social ! We're just trying to find time to scan the manuals. I've been told some of the Tandy VIS titles were made with this too - or at least it was available as an option.

@evi@meow.social @kieran@hom.ph That's why I have a drawer full of corks, plenty for both of you...

@hairymnstr@mastodon.social I'd love one, this is right up my alley.

@polpo@chaos.social I'm suddenly overcome by a desire to add this to Flashfloppy.

@glyph@mastodon.social It's certainly the future in writing valid-looking-but-terrible stuff which has subtle bugs and is hard for humans to review. If properly trained it /might/ be useful as a pattern-matching static analyser.

@tizen@meow.social I wouldn't pay Mario if he knocked on my door and said 'your toilet's broken, give me €100 and I'll fix it.'

@CliftonR@wandering.shop I think they had one through an acquisition but might have shuttered it. A lot of embedded companies up this way have gone that way sadly. Sadly doesn't look like they have much my skills could apply to but I'll keep an eye on it. Thanks.

@attie@hachyderm.io That's the fax I sent to it, to trigger the test. It receives a fax from you, then sends one back with the results.

@Nfoonf@chaos.social @da_667@infosec.exchange @cstross@wandering.shop It's the great equaliser: eventually the reaper comes for us all. And sometimes he even speaks in monospace.

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."
