We're going to be hiring someone to work on CHERIoT software things soon. Full remote, but UK Only (for various funding purposes, we need more people in the UK). Happy to talk to junior people who have some C/C++/Rust experience. You'll initially be mostly writing C++, though we expect this to move to more Rust over the next year or so.

Some of the job will be driver development gruntwork (here is a datasheet, here is a software interface for this device class, please write a driver for the device that exposes the interface), some will be at a higher level of the stack (so, how do you design a secure, compartmentalised {something} stack?).

If these sound interesting, let me know!

"Cars can be weapons, and the ubiquity of guns and cars in our society means a single crazy person is always going to be able to do huge amounts of damage if they want to. The only way to stop that is to limit them, which nobody in power seems to want to do."

"Tonight I typed just one sentence into Google Earth and put refugees near the Mexican border. Then I planted a nuclear plant in Iran. Then I put a fatal crash on a street in Amsterdam."

A friend’s dad was hit by a driver while riding in the bike lane. He’s a local musical legend who rode his 1973 Schwinn around Santa Monica daily. He’s recovering from brain surgery and multiple fractures. Please share if you can. I wish this kind of thing were already designed out of our streets. https://www.gofundme.com/f/help-stan-heal

Local stratum 1 GPS NTP time server, yay!

Now to see how it copes with sun and rain. The bag is an extra precaution. Tracking 36 satellites and using 19, over three networks.

Current PPS tracking with σ=16ns

Current jitter measured at FireBrick (NTP client) of 0.08ms, and latency of 0.7ms. Selected over any pool (via Internet) servers, understandably.

Good morning friends. What are your favorite blogs? Not newsletters, not news sources: personal blogs. I'm looking for replace some of my reading material and I am looking for bona fide humans words to put into my eyes. Boosts welcome. Thanks!

The kids are alright. From an email I received today:

I am writing to express my huge appreciation for your incredible work and dedication to maintaining curl—one of the most essential building blocks of the modern internet.

I am a 16-year-old IT student from Poland. Inside my home server laboratory, your tool is a vital part of my daily life. Whether I am writing backend web tools, integrating APIs, or creating system automation scripts, curl is always the absolute backbone of my setups.

I did Compiler Explorer's monthly accounts, and for the first time in ages we only broke even. Usually we run at a small surplus (which I save) & we have a year contingency saved up.

If you want to support us:

Would appreciate a repost - thanks so much! :)

"No mercury added" sounds a little suspicious...

Kernel Recipes 2026 registration will open on June 19. We will start publishing the conference schedule in coming days.

Stay tuned! #kr2026

On July 7th, the inimitable Shuah Khan will be interviewing me on my life as a Linux-kernel developer and maintainer. And it is not just every day that this old man gets an invitation to reminisce! Kidding aside, it has been an exciting journey, and I hope to be able to share some of that excitement with you. ;-)

Jeff Bezos went on TV to whine about Zohran Mamdani to stop demonizing billionaires and the very next day Mayor Mamdani responded by forcing Amazon to pay $9M in fines accrued by Amazon delivery trucks for illegally idling and blocking NYC traffic.

This is what happens when you elect a mayor for the people, not the corporations. We need more of this.

OK #Firefox users, this is a special request. I'm looking for someone with a high-end Raptor Lake machine that is experiencing instability in Firefox (or anything else for the matter). The best candidate is a CPU from the 13900* SKUs. K or not doesn't matter as long as it's one with the 8P+16E cores.

We have a potential workaround for one of the most common bugs of this CPU, but we need a broken machine to test it.

Does this count as a recession indicator? 😬

For context, when you unsubscribe from someone's Patreon account you are asked for your reason for why you're leaving, and these are summarised for the creator in the "exit interviews" section. This is a screenshot from that.

These days basically everyone is choosing the reason of "My financial situation has changed".

hahaa! Successfully removed all IR and UV filters from my old Canon EOS 600D, I can do full spectrum, UV and IR photography now!

All of the following photos have been taken with a ~550nm+ lpf, meaning cutting everything under 550nm (blue, purple and uv) off. I love the vibrant pink foliage and dramatic turquoise skies #photography
