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.

Wrote a custom C++ engine to render raw WAD geometry directly to the DAC.

Pure vector output, 1D occlusion culling, no rasterization tricks.

```/bin/bash``` just turned 38.

Happy birthday, bash!

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.

Happy 2026!

I'm working on improving on the Kap documentation, and I'm going to write (or maybe make a video) about how to work with external data, and I want to have a practical example.

I'm looking for some publicly available dataset in tabular form (CSV or spreadsheet format) that contains some interesting data that I can use in the examples. Preferably there are some interesting calculations that can be made on said data as well.

I want to demonstrate simple aggregations, grouping, sorting and visualisation of the data.

It's much nicer if I can show something that has some practical use than just generate some random data.

I might want to use the same data to demonstrate SQL integration too. Any suggestions on data and calculations that I can show would be appreciated.
