One of the things we did during the pandemic was significantly scale up or ability to sequence genomes. We were literally watching the virus evolve near real-time because a large chunk of samples could be sequenced and processed.

While they're are obviously data privacy concerns, for which the UK has a fairly long history of legislating for, having a full sequence for every newborn could allow for all sorts of cheaper early interventions. I'm sure the dataset would also be very useful for researchers as well.

I'd be wary of switching to a non-free license. The freedom to use for whatever is fairly core to the four freedoms. However all the main licenses specify the code is as-is and it's perfectly fair for the maintainer not to take on the unpaid burden on behalf of others making money with their work.

I think the first proper internet I had was downloading files from FTP servers at university. The first time I had it from home was over a modem to Demon ISP running some cobbled together TCP/IP stack for my Atari Falcon.

It was wild back then, I think even on windows you needed to install an IP stack before you could do anything because Windows didn't have one but default because why would you?

I remember when this guy came to power and the allegations of extra-judicial executions as part of his war on drugs. I didn't realise the ICC had caught up with him.

Wow - bonkers to have a warship that might not be able to feed its crew should it be in a war situation when they can't get the approved contractors onboard.

VirtIO was originally developed as a device para-virtualization as part of KVM but it is now an OASIS standard: https://docs.oasis-open.org/virtio/virtio/v1.3/virtio-v1.3.html which a number of hypervisors/VMM's support.

The line between what a hypervisor (like KVM) does and what is delegated to a Virtual Machine Monitor - VMM (like QEMU) is fairly blurry. There is always an additional cost to leaving the hypervisor to the VMM so it tends to be for configuration and lifetime management. However VirtIO is fairly well designed so the bulk of VirtIO data transactions can be processed by a dedicated thread which just gets nudged by the kernel when it needs to do stuff leaving the VM cores to just continue running.

I should add HVF tends to delegate most things to the VMM rather than deal with things in the hypervisor. It makes for a simpler hypervisor interface although not quite as performance tuned as KVM can be for big servers.

No the Apple hypervisor is called hvf, but projects like rust-vmm and QEMU can control and service guests run on that hypervisor. No KVM required.

virtio-gpu with Vulkan pass through for the VM with a Vulkan to Metal translator in host user space. There are various talks about this including at KVM forum: https://kvm-forum.qemu.org/2024/The_many_faces_of_virtio-gpu_F4XtKDi.pdf

Very expensive and still slower than an hard coded ASIC.

Sure if they needed to bypass ads I can introduce them to Free tube or whatever but for all it's sins they need moderated exposure to the YouTube experience so they're equipped enough not to go totally wild when they finally have unfettered access.

I thought my youngest was all about watching hour long Minecraft playthroughs but really they are quite interested in game mechanics and speed running. They are just a lot more tolerant of watching hours of videos around a particular game.

I don't overly police their content consumption (although we do talk about limiting shorts). The main thing is at the weekend to kick them off the TV after the morning to go and do something more interactive.

When we first let the kids watch YouTube it was on the main TV with it's own account. We have consistently monitored it and actively prune recommendations while slowly introducing them to the concept of "the algorithm". From secondary school they pretty much need YouTube on their own PC's for homework reasons and it's harder to totally lock down - we use the family link controls to limit it a little but if they tried to get around them they could. The hope is we've at least prepared them a little before they have totally unfettered access to the internet.

We did try YouTube kids a little but it was such a garbage experience we just blocked the app everywhere.
