Pandas 3.0 released

Version
3.0.0
of the pandas data
analysis and manipulation library for Python has been
released. Notable changes include a dedicated
string type (str)
, new “copy-on-write” behavior, and much more. This release also removes
a number of features that were deprecated in prior versions of pandas;
developers are advised to upgrade to pandas 2.3 and ensure code is
working without warnings before moving to 3.0. See the release
notes
for the full changelog.

[$] Responses to gpg.fail

At the 39th
Chaos Communication Congress
(39C3) in December, researchers Lexi
Groves (“49016”) and Liam Wachter said that they had discovered a
number of flaws in popular implementations of OpenPGP email-encryption standard. They also released an
accompanying web site, gpg.fail, with
descriptions of the discoveries. Most of those
presented were found in GNU Privacy
Guard
(GPG), though the pair also discussed problems in age,
Minisign, Sequoia, and the OpenPGP
standard
(RFC 9580) itself. The discoveries have spurred some interesting
discussions and as well as responses from GPG and Sequoia
developers.

The CPU Performance Of The NVIDIA GB10 With The Dell Pro Max vs. AMD Ryzen AI Max+ “Strix Halo”

With the Dell Pro Max GB10 testing at Phoronix we have been focused on the AI performance with its Blackwell GPU as the GB10 superchip was designed for meeting the needs of AI. Many Phoronix readers have also been curious about the GB10’s CPU performance in more traditional Linux workloads. So for those curious about the GB10 CPU performance, here are some Linux benchmarks focused today on the CPU performance and going up against the AMD Ryzen AI Max+ 395 “Strix Halo” within the Framework Desktop.

Linux 6.19 ATA Fixes Address Power Management Regression For The Past Year

It’s typically rare these days for the ATA subsystem updates in the Linux kernel to contain anything really noteworthy. But today some important fixes were merged for the ATA code to deal with a reported power management regression affecting the past number of Linux kernel releases over the last year. ATAPI devices with dummy ports weren’t hitting their low-power state and in turn preventing the CPU from reaching low-power C-states but thankfully that is now resolved with this code…

Adjusting One Line Of Linux Code Yields 5x Wakeup Latency Reduction For Modern Xeon CPUs

A new patch posted to the Linux kernel mailing list aims to address the high wake-up latency experienced on modern Intel Xeon server platforms. With Sapphire Rapids and newer, “excessive” wakeup latencies with the Linux menu governor and NOHZ_FULL configuration can negatively impair Xeon CPUs for latency-sensitive workloads but a 16 line patch aims to better improve the situation. That is, changing one line of actual code and the rest being code comments…

BentoIO CMX0 IO-Carrier Board adds low-profile platform for Raspberry Pi CM5

The BentoIO CMX0 is a low-profile IO-carrier board designed for the Raspberry Pi Compute Module 5, combining a compact footprint with onboard cooling and expansion support. It is intended for space-constrained systems that require access to standard Raspberry Pi interfaces while maintaining a reduced overall height. The CMX0 supports both Compute Module 5 Lite and […]

New Linux Patch Improved NVMe Performance +15% With CPU Cluster-Aware Handling

Intel Linux engineers have been working on enhancing the NVMe storage performance with today’s high core count processors. Due to situations where multiple CPUs could end up sharing the same NVMe IRQ(s), performance penalties can arise if the IRQ affinity and the CPU’s cluster do not align. There is a pending patch to address this situation. A 15% performance improvement was reported with the pending patch…
