I am Director of System Architecture at SCI Semiconductor and a Visiting Researcher at the University of Cambridge Computer Laboratory. I remain actively involved in the #CHERI project, where I led the early language / compiler strand of the research, and am the maintainer of the #CHERIoT Platform.

I was on the FreeBSD Core Team for two terms, have been an LLVM developer since 2008, am the author of the GNUstep Objective-C runtime (libobjc2 and associated clang support), and am responsible for libcxxrt and the BSD-licensed device tree compiler.

Opinions expressed by me are not necessarily opinions. In all probability they are random ramblings and should be ignored. Failure to ignore may result in severe boredom and / or confusion. Shake well before opening. Keep refrigerated.

Wow, #OVHCloud's customer support is really bad. They don't read the diagnostics that you've already done, they ask you to run tests that would give them no information (you've run iperf3 and it's fast with any remote client. Two other protocols are slow, but only over one ingress path. Please reboot into rescue mode and run iperf3. We don't know what information that will give us, but it's the next thing on the script and we have no actual brains and must follow the script). Oh, and they disappear for a week in the middle rather than responding to questions like 'what do you actually hope to learn from this test, do you have a hypothesis that would be either supported or contradicted by it?'

I definitely will not use them for anything important. I have a server with them that I was planning on moving things over to but I'm not even sure I want to trust them for personal stuff anymore, given that they are obviously completely clueless.

I guess the fact that their Kimsufi servers are so cheap (4x2TB disks in a machine for about £20/month) should have been a clue that they cut corners everywhere. I assumed it was just that the machines had already fully depreciated.

Are there any less-incompetent providers that offer cheapish (old is fine) machines with decent sized disks?

Can somebody please teach me how to use #FreeBSD PF+dummynet? https://lists.freebsd.org/archives/freebsd-pf/2025-July/000756.html
Re: Dummynet doesn't work with PF of FreeBSD 14RC3 and 14RC4

It’s always “of course I check the LLM output for errors” but they never say how they do that exactly.

I have a hunch they’re doing what’s colloquially called “lying”.

This is a post I didn’t want to write. But I am dismayed to see such a horrible person continue to be welcomed in the Open Source community — a community which is supposed to be inclusive regardless…

Starting to realise that the highest praise I give is:

They don't (often) make the same mistake twice.

It's rare, but the most important thing I look for in people I hire.

Infosec Community: “Aaaagh! We’re drowning!”

Infosec Vendors: “If we can’t be part of the solution, there’s money to be made in prolonging the problem.”

Software Companies: “Check out this new cool AI button we added!”

life is like a roguelike: "it's so over" "we're so back" "it's so over"

@SrRochardBunson
Functions of the same crisis. Can't pass the test without being tested, The future awaits and we, as a species, will get exactly what we deserve.
Its fair to blame our predicament on the few at the top. But they got there because we, as a species, let them.
We abdicated our joint responsibility for the sake of convenience. Maybe we didn't realise because we were mislead, maybe we changed out minds when we grew up and realised, but by then it was too late.
A better world is possible FOR THE RICH and YES, we're so fucked. :XD

@abhijith hear me out, though.

What if...there were no more billionaires?

Then people will be out in the street singing.. "Heal the world... make it a better place... for you and for me and the entire human race..."
@SrRochardBunson
Will they exploit labor so much they'll all become trillionaires?
@abhijith

We will take over the government and claim their trillions.

@SrRochardBunson Yup Yup and again Yup but I refuse to stay silent

@Robo105 the one thing I know for sure is that we can't and won't stay silent.

Silence is complicity & complicity is guilt.

@SrRochardBunson That's a Schrödinger's something. Please don't collapse!
@hirunatan you're in good company. I somehow manage to alternate so fast, that is seems like I'm both at once.

@SrRochardBunson

😂 😂 😂

Seems to be a good solution.

@SrRochardBunson it's "yes and"

@SrRochardBunson I feel seen.

@SrRochardBunson A better end of the world is possible!
@SrRochardBunson Yeah. So, I kind of collected all the important intel on this. And WW3 is the most likely outcome now. Best case scenario a cold war 2.0. Not looking like it. Probably worth looking for a farm to work on.
@SrRochardBunson Both are true: a better world is possible but, for the time being, we're so fucked.

@iviyohane 🎯 I can't argue with that.

Time to start building that better world, from the ground up. Local as shit.
