Decomp2dbg:

"decomp2dbg aims to shorten the gap of context switching between decompiler and debugger by introducing a generic API for decompiler-to-debugger symbol syncing."

Day 13 of Advent of Compiler Optimisations!

You're calling a function inside a loop, but its result never changes between iterations. Does the compiler spot this and hoist it out? Turns out the answer depends on which compiler you use! Clang pulls off the optimisation beautifully, but gcc stumbles—even with explicit hints. What's going on?

Can anyone test my *SMALLEST* SSHD backdoor?

- Survives updates.
- Does not use ~/.ssh/authorized_keys or PAM modules.
- Does not create any new file.

Just SSHD trickery.

Day 12 of Advent of Compiler Optimisations!

Your loop checks the same condition every iteration, even though it never changes. Seems wasteful, right? The compiler thinks so too—and its solution is something that sounds completely backwards. Making your code bigger to make it faster? What's the trick?

@dey "flying in airplanes used
to be fun, but now it resembles a dystopian bin-packing problem in which
humans, carry-on luggage, and five dollar peanut bags compete for real estate while crying children materialize from the ether and make obscure demands in unintelligible, Wookie-like languages while you fantasize about who you won’t be helping when the oxygen masks descend."
