One of the new features for Linux 6.8 that was merged late was enabling the -Wstringop-overflow compiler option to warn about possible buffer overflows in cases where the compiler can detect such possible overflows at compile-time. While it's nice in theory, issues on GCC has led Linus Torvalds to disabling this compiler option as of now Linux 6.8...

Back in November 2022 AMD announced Brotli-G for GPU-accelerated Brotli compression. Brotli has proven very worthwhile for compressing web assets and other material while AMD's Brotli-G modifies the bitstream format to be more optimal for handling by GPUs rather than just relying on CPU (de)compression. Today Brotli-G 1.0 was finally released...

Posted at the start of 2022 was a set of 2.3k patches dubbed "fast kernel headers" to massively speed-up build times for compiling the kernel and to address dependency hell situations. While it was quick to iterate at first and some bits got upstreamed, it's been months since hearing anything new on the fast kernel headers topic. But today a new patch series was posted that's restarting the effort in working towards massively speeding up kernel build times...
