So, I’ve got an if statement that stops working at opt-level 2. It’s just checking a value != 0, and it’s looking at the wrong value. Is it a compiler bug or did the optimiser catch me doing a UB somewhere else?

SPARC box go brrrrrrr

Okay, I definitely want to watch Jason Statham Stole My Bike (whenever it releases) because why wouldn't we enjoy Jason Statham playing the role of Jason Statham? #FilmSky

Hell yeah, Cortex-R (ARMv7-R) support in probe-rs :D github.com/probe-rs/pro...

I bought a Brewdoni at Bird&Blend in York and it’s changed my life. It’s so good.

RetroFest 2026 is happening again in Swindon 30th and 31st of May. youtu.be/DScdsdFIP_A?...

While #DarwinDay is certainly a day to celebrate #CharlesDarwin and how he fundamentally changed humanity's understanding of all life on Earth... It’s also the perfect excuse to share this letter he wrote while being magnificently grumpy about bees 🧵

Stagecoach Guided Busway B from St Ives to Huntingdon is scheduled at 33 minutes and run two an hour. It was 20 minutes late and took 50 minutes. And I had a train to catch. Luckily I decided to take the a bus 30 minutes earlier.

Truly amazing work by GitHub here.

Ouch. This hurts.

Cool, cool, just Github dropping my release job into "Waiting for a runner" purgatory and ruining my day.

“There is no step function in quality of work in the history of human achievement that happened because people one day woke up and decided to be better at their jobs. Improvements [..] happen because of the invention of new techniques, processes, and tools.” Great paper.

TFW when you check the date on the milk you’ve been drinking all week and it went off at the start of the week.

Night Manager 2 - bloody hell.

People give Raspberry Pi a lot of crap, but I've just been given a PandaBoard and ... there's nothing left of the support it once had. It's basically all gone. However, I can still put the latest Debian on a 2012 Raspberry Pi 1. I mean, it would suck, but I can. All the support still exists.

YES! *dances around the workshop* This is the disk that made me buy this drive, and it’s only gone and done a 99% image of it 🎉🥳 Crucially, this means I have a copy of the only source file for the D8741A tape controller in the Executels. Beer time! 🍻 £250 well spent.

This crap should be illegal. Sort it out Apple.

I had a bad day debugging stuff yesterday but I don’t think I let on… github.com/thejpster/aa...

The PicoIDE Crowd Supply campaign is now live! Back the project to be among the first to get yours! PicoIDE is an open IDE/ATAPI drive emulator for retro systems. www.crowdsupply.com/polpotronics...

Throw a chair. Sieve the greens. Peel a parsnip. Andy Burnham! If you know you know.

Fat of the Land - still a banger

I have a SPARCengine Ultra AXi - an ATX OEM board from Sun with an UltraSPARC-IIi processor. It is in a stupid gamer case with blue LEDs, because it's funny. But what OS should I install on it?

This is good advice. I wonder if the speech was recorded. blog.moneysavingexpert.com/2025/01/five...

github.com/orcwg/orcwg/... > Anyone who incorporates AI-generated code into their software today is often already acting with conditional intent – and making themselves vulnerable to claims for damages, injunctions, and even criminal consequences. Yikes.

How it started ... How it's going

Apparently I got bored of writing software in Rust, so I'm now writing software in Rust that writes software in Rust. It's much harder.

Didn't expect to see my name appear in this BBC News article. www.bbc.co.uk/news/article... It does however mean I instantly know which town the photograph is from. As far as I know, I only have one Art Gallery named after me. (It isn't named after me)

Quick question - which is faster at Mandelbrot? PowerPC 740 @ 266 MHz (gcc 2.95 on Debian 3.0) or MIPS R5000 @ 200 MHz (MIPSpro 7.4 on IRIX 6.5)?

You could watch a nerve-wracking horror movie, or you could attempt to remove the second drive bay cover from a beige Power Macintosh G3 without snappging it. I think I need a lie down.

Do you remember 3D TVs? How every big TV came with 3D glasses and every movie was in 3D? All the glowing reviews for how the new 3D thing was even better than the last, right next to big shiny adverts for them. I’m glad we all moved on from that.

I call on my party and my government to remove themselves entirely from X and communicate with the public where they actually participate online and can be protected from such illegality.

Which is mildly entertaining until time passes and someone without that knowledge stumbles onto something edgy and gets themselves killed. Now we get to Generative AI. 10/

My Dell is proving useful today! It's a Precision T3400 with a Core 2 Duo, running latest Debian Trixie. But more importantly it has a 3.5" Floppy, SATA, a GPIB card, an IDE card and a SCSI card. Today it's taking a backup of the 18GB SCSI drive from the SGI O2.

I have two Arm-based desktop computers on my desk. One is 81,000x the speed of the other, based on my mandelbrot benchmark. That is not a typo.

I'm adding `-msoft-float` to speed up my floating point operations by a factor of about 5.

All you really need to know about embedded systems is that an MPU has an MMU whilst an MCU has an MPU (no, a totally different kind of MPU).

I lost a couple of hours today trying to use a BlueSCSI HDD image with SCSI ID 0 on a Silicon Graphics machine... (one where the SCSI controller is on ID 0)

We are working to restore service. Apologies for the disruption!

Does anyone know how to wire an eject button to a @bluescsi.com DB25? I'm trying to install IRIX from 7 CD images and it's very painful having to remove the card every time I want to swap CDs.

Ugh, VFAT is a trip. But now I can open files based on their long file name. github.com/rust-embedde...

Another LGR Christmas thing! Watching/reacting/researching stuff in the Computer Chronicles Christmas Buyer's Guide from 1987 youtu.be/bWXLDfbmpU8 And that's it for both holiday videos and LGR overall in 2025. Have a happy new year and I look forward to getting back to more LGR things in January 🎉

I made a joke in my main Discord server about DOOM E1M1 being in a major key and @abigbagofkeys.sickonedude.com actually made it. Jesus fucking Christ listen to this hahahaha

Does anyone know how to *actually* get U-Boot working on a Raspberry Pi 3B (not a B+)? I followed a dozen guides online and nothing works. Just get a rainbow on HDMI and nothing on UART. Have tried macOS and Debian hosts.

We’re looking for a Werkstudent:in in Germany to help work on rust-analyzer, the open-source LSP server behind Rust editor features. Paid student position. 🦀 Details → ferrous-systems.com/blog/student...
