I've started writing a short intro to KVM and realized all C struct visualizers suck, so I had to make my own pictures by hand. Still doesn't look like I imagined it in my head.

I’m very excited to announce that we at V8 Security have finally published our first version of Fuzzilli that understands Wasm! Go check it out at https://github.com/googleprojectzero/fuzzilli. While we still have a way to go in improving it, we think it shows a promising approach!

Refuting a bullshit bug bounty report from (probably) a LLM is my least favorite way to spend my friday afternoon. What a waste of time and energy. Hashtag BegBount.

I've started using ghostty (as an experiment). I like it, it works well and I really like the default theme. Right, I love how it looks but I have zero idea what it is the default theme. It just doesn't seems to be saved anywhere so I can't set the same theme in all other apps. I'm sad.

In the end everything was ok. It turned out all components were working correctly but for some reason my monitor wasn't. It was strange - laptop connected via usb-c was ok, but display port was not. Troubleshooting tip: never assume anything, check everything.

Bit unorthodox, but ... Watching videos like www.youtube.com/watch?v=Y891... gives me some thought. If you are a large organization looking for a PM, TPM or a manager you should have your recruiters trawling games like this (or EVE) in search of a capable candidates.

Last PC I built from scratch was almost 10 years ago. I was not looking forward to the next one - I hate cabling, I hate how modern PCs are just a nest of wires and there is a little elegance while one crams all those unwieldy cabling around the badly manufactured chasis.
