It would be sometimes useful if #QEMU w/o libvirt could interpret domain XML to some level.

Like for instance if you want to CI kernel, that would be one use case for this.

For the sake of example, here’s the QEMU command-line that I use as starting point for any kernel testing/CI:

qemu-system-x86_64 \
  -M pc \
  -monitor unix:monitor.sock,server,nowait \
  -serial unix:serial.sock,server,wait \
  -drive file=disk.img,if=virtio,format=raw \
  -net nic,model=virtio \
  -net user,hostfwd=tcp::10022-:22 \
  -rtc base=localtime \
  -nographic \
  -chardev socket,id=chrtpm,path=${SWTPM_DIR}/swtpm-sock \
  -tpmdev emulator,id=tpm0,chardev=chrtpm \
  -device ${QEMU_TPM_DEVICE},tpmdev=tpm0 \
  -bios /usr/share/edk2/ovmf/OVMF_CODE.fd \
  "$@"

These people are not real. Just like from some bad 70s/80s B films. I bet he does "evil laughter" in front of mirror or something o_O https://edition.cnn.com/2024/08/15/politics/russ-vought-project-2025-trump-secret-recording-invs/index.html

First pull request in preparation after holidays and it is over two weeks past. I blame all those nasty interviews ;----)

I had also NVidia interview this week (which went well but I decided to took a position already offered elsewhere) and in that interview I was asked stuff about virtual memory.

Without going details on questions concerning I said that security USED to be a property why we use virtual memory ;-) Now it is the place inhabited by the seasonal flu with its various generations, i.e. Spectre.

If you want to feel how it feels to make hole with a street drill to your skull, try watching Project 2025 videos uncut ;----) Was an epic failure

I wonder how these AI crawlers verify that the code they feed to LLM is not copyleft licensed? Like GPL for instance? It could mean huge legal risks for companies, if fragments can be later on identified.

I don't know what it is but if I have interview with 20 minutes live coding I sleep for the rest of the day. Does not have to be that complex task, super exhausting. Last week I had like two of those and one technical interview, not much else accomplished.

Do not know much about #politics but I like people who appreciate great audio equipment ;-)

I really would like to test out GCC-Rust. What would be the easy path? I'm using Fedora across the board in my Linux systems.

All my quantum knowledge is based on

1. Physics lab exercises while studying for my MSc (back in the day).
2. Applying numerical methods to cost functions while studying for my MSc.
3. Quantum Computing at https://brilliant.org/

I thought that since I'm ultimately stupid in this topic and want to get the gist of it, Brilliant was exactly in my level :-) It really helped me to get the gist of the topic by combining it to my knowledge of stuff that I learned while studying ages ago at a polytechnic university.

Can highly recommend that course!

And can highly also recommend studying topics that you suck at, not ones that you're good at. It is refreshing!

If you have gone through a basic lab course e.g. in a polytechnic university AND know how to re-formalize an algorithm as a cost function, and apply numerical methods for that, you already have the basic theoretical and practical experience on how to program quantum computers.

That's roughly all there is to it.

Have some catching up to do with #LKML as I was going to job interviews last week and did not have energy to do much else. Also need to some bug fixes to Linus for 5.11.

Anyway I accepted an offer with all the usual suspect hype words except AI: Rust, RISC-V and blockchains ;-) More on that later...

Looking at delays among different CPU and chip companies (not just Intel), maybe there's a CPU bubble coming too in the timeline (long projection)?

E.g. Spectre and its ancestors are so fundamentals flaws in the core design decisions of a CPU that I don't think they will be ever fully fixed in ARM and x86.
