Since https://github.com/RustScan/RustScan claims to be fast I tried first a trivial SYN scan to my file server:

sudo nmap -sS -p- haaparousku

I got the list of ports in about one second (bit more or less). Then I tried rustscan and got bored enough to finally SIGINT it:

rustscan --addresses haaparousku

Not sure I get the improvement here… Also command-line is not “tactile :-)

Something definitely to improve in Rust command-line apps is not to think arguments as an object tree that you feed into clap crate. That’s just lazy.

Instead a better metaphor for a great command-line interface is something like a game pad that you can “play” easily. That’s why nmap has been relevant for decades.

I guess I could create my own XML parser which then outputs run-qemu.sh.

I even used to bootstrap qemu and swtpm for every single build at one point ;-) It is great when testing kernel features when you can always start from known state.

@stsquad I generate the whole operating system for each kernel test build. I don't have a machine description when I start compiling it.

Essentially each test VM is also one shot, deleted after a single test run.

Basis is like https://codeberg.org/jarkko/linux-tpmdd-test

@janotomko It would be easier to have a few template configurations and XML can be more easily post-manipulated.

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 ;----)

@vitaut Tbh, this would apply better on Rust than C++, given that usually C++ developers do not impose blind trust on compiler ;-)

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.

@guenther GPL has been exercised in court successfully in the court in the past. It is more about can you project it back to the original source code. I don’t know. [Or could you trick AI in adversary manner to learn code that is ”watermarked”]

Or is the attitude more like "we don't care, see you in court"?

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.
