On recent builds of Ubuntu 26.04 when being prompted by sudo for the password, password feedback is now enabled by default to show asterisk (*) characters when inputting your password. Traditionally sudo has not provided password feedback in the name of security to not divulge the length of your password in case anyone is looking/capturing your screen. But upstream sudo-rs has now changed the default behavior in the name of an improved UX...

Microsoft has published a new version of its open-source DirectX Shader Compiler. Besides adding Shader Model 6.9 production support, making this DX Compiler update interesting to us are the SPIR-V back-end improvements and enhancing interoperability with Vulkan drivers...

For those curious how far Intel laptop CPU performance has evolved over the past nearly two decades, here are power and performance numbers when re-benchmarking all of the Intel-powered laptop CPUs I have on hand that are still operational from Penryn to Panther Lake. A ThinkPad from 2008 with the Core 2 Duo T9300 "Penryn" was still firing up and working with the latest upstream Intel open-source Linux driver support on Ubuntu 26.04 development. On a geo mean basis over the past 18 years from Penryn to Panther Lake, the performance was at 21.5x in over 150 benchmarks. At the most extreme was a 95x difference going from Intel's 45nm Penryn to the 18A Panther Lake.

While the Linux 7.0 feature merge window ended this past weekend and that next kernel release won't debut as stable until April, there are already features out on the horizon that are being positioned for likely merging into the Linux 7.1 kernel assuming no issues appear or objections raised by Linus Torvalds. One of the features already looking like it will be submitted for Linux 7.1 is supporting extended attributes on sockets...

With yesterday's stable release of the LLVM Clang 22 compiler it didn't take long for Phoronix readers to begin asking about the performance of this half-year feature update to this prominent open-source C/C++ compiler. What I am seeing so far are no big surprises with the performance largely being similar to Clang 21 across various open-source C/C++ workloads in the testing thus far. This initial round of reference benchmark results between LLVM Clang 22, Clang 21, and Clang 20 were done on an AMD EPYC Turin (Zen 5) Linux server.
