Took some time to improve a few things on WinDiff (added permalinks, filtered out empty results) and added a Claude skill to easily use WinDiff to produce quick security-oriented diff analyses between binary/OS versions. Feel free to try! github.com/ergrelet/win...

So I've been trying to dev an app using LLMs for a few weeks now, and I couldn't ever reach a satisfying state. Either talking to LLMs is an incredibly hard skill, or they are still very limited. I'm not even sure it would ace it if I asked it to write it in JS.

Opus 4.5: "Given this limitation with split DWARF, let me take a different approach: parse the project source code to extract the class hierarchy. But that's complex..." (proceeded not to do the "complex" implementation) What are LLMs good for if they are lazy?! 🤣

I reverse engineered DexProtector, the security solution protecting applications like Revolut and other banking apps. From custom ELF loaders to vtable hooking, here is an insight into how these protections work and their limitations. www.romainthomas.fr/post/26-01-d...

TIL about llvm-mca and its -timeline option, pretty cool for getting an understanding of instructions scheduling. Thanks Matt!

Day 9: Why does the compiler keep an "expensive" multiply in the loop instead of using clever addition tricks? The slower operation enables something more valuable. What's the hidden benefit? xania.org/202512/09-in... youtu.be/vZk7Br6Vh1U #AoCO2025

I read the news about the React RCE but completely forgot I was hosting some React stuff! One of my server got pwned at least by 2 "attackers" only to download the same version of xmrig and run it... Disappointed.

I wanted to praise how @bsky.app was better than X after I couldn't reach it through IPv6, but actually I couldn't reach Bluesky neither. Sadge.
