For those wondering how GCC and LLVM Clang are competing when running on Intel's latest Rocket Lake processors, here are some GCC 11 vs. LLVM Clang 12 compiler benchmarks with the Core i9 11900K running from the newly-released Fedora Workstation 34 featuring these very latest compilers. The compiler benchmarks were carried out at multiple optimization levels on each compiler.

More than a decade ago when the open-source graphics driver stack was being modernized with kernel mode-setting and better handling the stack for OpenGL, composited desktops and the like, TTM (Translation Table Maps) was born for managing GPU video RAM by the kernel Direct Rendering Manager drivers. While Intel initially expressed interest in TTM, they ultimately decided to create GEM as the Graphics Execution Manager for handling their video memory management needs. Now in 2021 with Intel aggressively pursuing discrete graphics, they are working on TTM support...

It's been a month and a half since AMD published a security analysis of their new Zen 3 "Predictive Store Forwarding" feature that while helping performance could theoretically lead to a new side-channel attack. While they published a Linux patch to allow disabling PSF if desired for increased security, to this day they remain in the works and have yet to be mainlined...

Back in 2007 Apple effectively acquired the open-source CUPS project and in 2017 then decided to no longer develop CUPS under the GPL but instead the Apache 2.0 license for this widely-used Unix/macOS/Linux print server. But then at the end of 2019 the CUPS lead developer left Apple and following that public development of CUPS seemingly halted. Fortunately, now there is a happy next chapter to the CUPS printing story...
