I'm declining to publish the next PR for my open-source project because it's just too good and I don't think you're ready for it. It's not because it's simply not finished. Trust me.

Universal Signalling and the Ferrocene team are developing the first railway certification package for Rust under EN 50716, establishing a pathway for Rust in safety-critical railway applications. Read more: bit.ly/4z193o6 #UniversalSignalling #Ferrocene #RustLang #RailTech

The Observer’s editorial today is about how Andy Burnham should “channel the white heat of AI to make the government more responsive, make the economy more attractive to investors, and – as promised – improve people’s lives” What would improve my life is not having to read this bollocks.

I’ll be at NDC TechTown this week, on the @ferroussystems.bsky.social booth. If you’re curious about Rust and want to know what the leading players are up to in the space, or if you’re ready for training, or tooling with long term support, drop by and say hello over the next two days.

That’s a wrap on Oxidize for this year. I was running the Ferrous table, dipping in and out of the talks, and having a ton of great conversations. Shout out to Sabine, who was hard at work MC’ing both days, and to my colleagues Charlotte, Tobias and Jessie who put so much work in to make it happen.

Ok, time to actually do some packing. On Monday I’m taking the train to Berlin. I’m doing the booth at the Oxidize conference. Saturday I’m taking a train from Berlin to Oslo. Probably Sunday too. Maybe Monday as well? Then I’m doing the booth at NDC Techtown. Then flying home.

If you type text into a box on a website and click a button to send the text to the website owner, the website owner gets the text you typed into the text box. And if the website owner is super keen for you to type text into that text box on their website, there’s probably a reason for that.

‘Honest Bob’ Jenrick says he wants to “abolish” Natural England, and at the very least stop funding it, in the first 100 days of a putative Reform government. Reform may appear to be on the rocks currently but their plans are terrifying, mad & must be stopped. www.theguardian.com/politics/liv...
Jenrick: “Even if you can’t abolish, I don’t know, Natural England within the first 100 days, you can stop funding it, you can turn the tap off and the tap will be turned off a lot of these quangos, and that will drive savings.”

I still cannot work out how to make cache coherency work. 1. I've invalidated and then enabled the SCU 2. I've set the SMP bit and the FW bit in the ACTLR 3. I've set the L1 page table entry to WriteBackWriteAlloc 4. I've turned the MMU on 5. I've used Altera's code to invalidate/enable L1 and L2

Godbolt's Compiler Explorer now supports build systems (like cargo). This is so cool! I use Compiler Explorer quite a bit when playing with AArch32 stuff in Rust, to check I'm getting the kind of instructions I expected but I was limited to single files. Having cargo support is game changing.
