I have fond memories of parsing random things to pipe to gource as a younger me. The code is ancient, but here [0] was an experiment to get something like nmap (and other data) ready to feed to gource. Fun to watch indeed!

Curious about this statement. Can you link to any reading I can do to learn more?

Creation is done by running migrations [1] (invoked via Laravel's artisan command line). Using the database is done via Models[2].

This is fun! I was curious about pulling something like this off in Golang, and wipped together a dirty PoC using Traefik's yaegi here [0]

New comment by leonjza in "Firecracker v1.0 Released"

leonjza — Mon, 31 Jan 2022 15:38:50 +0000

Happy to see the kernel init parameters fix land! For context, I used firecracker (very successfully) in a CTF, driven via a Discord bot.

One of the challenges I tried to build was one where a player would get access to the kernel commandline with the goal being that they should hack their way around the environment to get access to an encrypted disk. Unfortunately, that was when I get the now fixed bug[1].

I really enjoyed the debugging process here, and am glad to have learnt about the -k flag which seems to only be available on systems with strace version 5.5, at least for me.

As for the patch (and my love for all things Frida [1]), I think a call to Intercerptor.replace() after locating the symbol with Module.getExportByName() [2] would make for a simpler patch (at the cost of installing Frida). For example:

  const sym = Module.getExportByName("lime.ndll", "SDL_SemWait");
  Interceptor.replace(sym, {
    onEnter: function() {},
    onLeave: function() {}
  });
