Just stop fucking using the slop machines and rewarding the slop purveyors because the rest of us are going to be unfucking your slop for the next decade as is.

I've been working with @A2_Canada to image, verify, and provide complete metadata for a number of scenario disks by Strategic Studies Group. SSG was an Australian video game developer+publisher that specialized in hex-based wargames. They had a multi-year print run of a magazine ("Run 5") devoted to these games and the community that centered around them. The magazine included type-in variations that nobody actually wanted to type in. They quickly started selling the variations on floppy disk.

Dreaming of your own Airbus cockpit? ✈️

We are proud to sponsor @flyfly's Open Source A320 Home Cockpit. Built with KiCad, Rust, and 3D printing, this project turns a "wire mess" into a sleek, reproducible simulator.

Easily the brightest and most widespread aurora I've seen from the west Highlands of Scotland.

The intro from "Another World" (1991) still manages to impress even decades later, which is why I feel like it's nearly impossible to describe emotions one felt upon encountering it 35 years ago for the first time.

Suddenly a loud bang from the lab at the local #hamradio club ‼️ 💥🤯

Luckily nothing happened to the people in there, but I guess it’s safe to say that this vintage capacitor decided to quit its job 😂

Always wear safety glasses 🥽 when testing and troubleshooting #electronics, especially if it’s vintage gear where you have no knowledge of its state and health☝🏼

I wanted to make the world's fastest yawl, so I made the aft sail bigger, but apparently that means it's not a yawl anymore! It's a real ketch-22.

With 6.0.8, I closed a huge milestone for radare2 , after 20 years of development (yeah, radare was born in 2006) we are finally leak free! 🥳

To ensure that, a new category of tests for r2r (the testsuite runner of radare2) using Valgrind to ensure not a single byte is lost after parsing different file formats and analysing. Thanks to heaptrack and the leak sanitizer to help me debug all those leaks.

This is not the only breakthrough related to memory usage that's shipped in this release. An custom arena allocator is now available inside r_util, so we can pack all allocations for a specific code in a single chunk and free it with a single heap call.

The old and under-performant RVector struct has been fully replaced with RVec, introducing several performance improvements and better usage of linear memory for arrays of structs. Kudos to @luctielen for the new implementation sponsored by @NowSecure !

Several global variables has been refactored into instance scopes, opening the door to the upcoming multi-thread support I plan to achieve it this year.

Another huge effort has been made along last year with me putting the focus on taking care of the most critical clang-analyzer and scan-coverity issues, solving more than 1000 security issues in the 2 Million lines of code of radare2 (as well as contributing to the ones in third party projects like zlib, capstone and quickjs-ng).

Release builds are also stripping about 900 debug messages, making the execution faster and libraries smaller.

All those changes has been achieved with focus on reducing code complexity, reducing lines of code and as long as the heap is more relaxed, the CI runs 20% faster and the asan jobs no longer timeout.
