The BLAKE3 cryotpgraphic hash function that was announced last year and based on its predecessor BLAKE2 has now reached version 1.0 for its official/reference software implementation. BLAKE3 continues to be much faster than BLAKE2 while also being much faster than the likes of SHA-1/SHA--2/SHA-3 and even MD5 while being more secure...

When sticking to Wine recommendations of maintaining separate prefixes per-application, a lot of system files get duplicated for each game/application and in turn leading to significant bloat. With the current state of Wine it can mean hundreds of megabytes per prefix in duplicated files. But proposed reflink patches for Wine are aiming to cut down on this severe bloat...

This past week were the initial Linux benchmarks of the Ryzen 9 5900HX with the ASUS ROG Strix G15 laptop. Ubuntu was used as the default test platform as usual given its popularity and arguably the most relevant Linux distribution to use given that it's the most common Linux distribution at the moment for preloads on laptops by multiple vendors. In any case, as usual many users were quick to say "but Arch Linux!" as if it was going to make a dramatic difference in my findings. Well, here are some Ubuntu 21.04 versus Arch Linux benchmarks on that AMD Advantage laptop.

One of the low-level exciting kernel advancements being worked on at the moment is the new "folios" struct for improving Linux memory management.

With an AMD Ryzen 9 5900HX Zen 3 processor and Radeon RX 6800M graphics, the ASUS ROG Strix G15 laptop may be promising for those wanting high performance and graphics backed by AMD's much enjoyed open-source Linux GPU driver stack. Plus this ASUS ROG Strix G15 (G513QY) is one of the first two "AMD Advantage" laptops. But when it comes to using it on Linux, it's not without some struggles before being able to enjoy the compelling performance.
