@dick_turpin and not a cheap one either. Are those the actual electronics it uses or some printed PCB for the image?

Currently getting the run around between and trying to work out who is responsible for the fact their is no coverage for meters where I live. Of the 2.5MWh the household has consumed from the grid this year alone I've sent 1.5MWh back into the grid. There are only so many free showers I can have by diverting the spare energy into my hot water tank!

@penguin42 I have plenty of mobile coverage on both 3 and EE so I don't think that should be an issue. But the main thing is its not entirely clear who supplies the WAN for my region or indeed what technology its using.

@stsquad@mastodon.org.uk avatar

@penguin42 that seems to be the way it needs to go. themselves don't claim to regulate the WAN networking for the smart meter network although they weren't sure who did or if indeed it was regulated. I did find this: https://www.smartdcc.co.uk/about-dcc/governance-regulations/smart-dcc-licence-regulation/ which implies a license expiring next year which might explain why things have gone to shit.

Not sure - I think the actual tech they use varies by region. I believe their is a 3G to 4G network migration going on as well.

As I knew I was on holiday for soft freeze I got all my #qemu maintainer PRs in early for 9.0. It is now released to the wild. The big #arm64 update is FEAT_NV2 emulation as well as a number of enhancements to various board models (and some deprecations of the older unloved code). For #tcg #plugins we now support reading register values as well as a new thread-safe inline ops API. The #gdbstub also saw a number of tweaks. More to come for 9.1 and the tree is now open ;-) https://www.qemu.org/2024/04/23/qemu-9-0-0/

@bugaevc Christopher Dall did build an EL2 kernel although none of the code was upstreamable - it was mainly an exercise to show what needed covering.

@bugaevc it's been awhile but I think NV1 was just the first iteration and NV2 picked up some missing bits without which NV wouldn't work.

I've finally finished a post I started about 2 weeks ago on my experiences with 's like . Unlike the last post it was 100% written by me which explains why its taken so long to finish 😄 It's very much from the perspective of someone who's a novice still learning about how these things work: https://www.bennee.com/~alex/blog/2023/12/10/a-systems-programmers-perspectives-on-generative-ai/

After ten years I've finally decided its time to upgrade the work machine. It's mostly driven by the fact I'm building bigger and bigger things now (kernel + full rootfs, android) but I've also taken the opportunity to move from a 2 to 3 monitor setup. It's arrived now so tomorrow is going to be a day on cleaning, unpacking and re-arranging my work environment.

It seems the topic of vs based workflows in software is a topical subject so I thought it an opportunity to generate a blog post: https://www.bennee.com/~alex/blog/2023/10/22/comparing-forge-based-and-email-based-workflow-for-open-source-projects/#comparing-forge-based-and-email-based-workflow-for-open-source-projects

I don't understand why the procedure for migrating between and devices can't be as simple as creating a zip file in and then just copying it into . The lock-in effects are great.

Having watched the first episode of the new season of I can only conclude Lee Pace has a contractual agreement for a certain number of shirt-off minutes per episode. If you've done the work I guess you want to flaunt it 🤣

@stsquad@mastodon.org.uk avatar

I'm finding the "outrage" about change of subscription terms very weird. Open source development happens in the repos and the only people that really care about the source for downstream binaries are those with the binaries. 's limiting of RHEL clones does make it slightly harder for projects to ensure loops run on those distros. However Red Hat are big enough to take on those responsibilities in house and report back when regressions happen.

So this #blog post is definitely outside of my comfort zone so apologies in advance for any mistakes. The post provides an overview of various approaches to #gpu virtualisation and the interactions with #virtio. We are still exploring the options for the final GPU solution for Project Orko on #xen.
