This page links to various Linux performance material I’ve created, including the tools maps on the right. These use a large font size to suit slide decks. You can also print them out for your office wall. They show: Linux observability tools, Linux static performance analysis tools, Linux benchmarking tools, Linux tuning tools, and Linux…
We have a Ruby application running on Ubuntu x86 Linux. Development is done locally on the developer’s machines using Vagrant managed VirtualBox VMs. File synchronization is handled by vagrant rsync. NFS and the built in VirtualBox file sync were not performant. By coincidence all developers use Macs – they choose their hardware. And they wanted…
It all started this month last year In March 2022, the alpha release for Asahi was made available and I immediately installed it on a Mac Mini with an 8-core Apple Silicon (ARM64) M1 processor. Asahi is a Linux distribution that can run natively on Apple Silicon-based Macs due to some slick reverse engineering provided…
Opinion Even now, I run into those who think Linux and open source software is made by people living in their parents’ basement and writing the code out of the goodness of their hearts. Wrong. So, so wrong. Yes, even now, some people write open source code to scratch an itch or just because they…
EasyOS Kirkstone-series version 5.0 February 26, 2023 — BarryK I started work on the Kirkstone-series early in December 2022. There have been two Release Candidates, discussed in this forum thread: https://forum.puppylinux.com/viewtopic.php?t=8072 I also receive feedback via direct email. Finally looking OK, so version 5.0 is now out. Here is a summary: Almost all of the…
A patch series started by Intel to improve the Linux kernel’s fair scheduler code, which has also seen testing/feedback from AMD engineers and other stakeholders, continues to be improved upon. The focus of this patch series is on avoiding too many cross-CPU wake-ups when they are unnecessary. In doing so, these patches help enhance the…
Linux 6.2 was released yesterday, and Linus Torvalds described the latest Linux kernel release as, “Maybe it’s not a sexy LTS release like 6.1 ended up being, but all those regular pedestrian kernels want some test love too.” For once, I disagree with Torvalds. By adding upstream support for the Apple M1 Pro, M1 Max, and M1…
This is a huge milestone, following the last piece of news in Q4 2022 when better compatibility was achieved. PtitSeb, the developer behind Box86 and Box64, has just managed to fix the issues that previously prevented Box64/Box86 to support the Full Steam client – while it was still possible to use the mini mode. Most…
Part 2 This is the second half of a feature about work undertaken to harden and improve Linux, beginning with part 1 here. Commercial Unix was expensive so it was carefully tended – and indeed tendered. Linux is free so it has to fend for itself. Linux itself was inspired by the tried and tested…

Mycroft AI, creator of a Linux-based virtual assistant, announced on Friday it would not be able to fulfill rewards for its Mark II Kickstarter campaign. Furthermore, without immediate new investment, the company will be forced to cease development by the end of the month, said the company’s former CEO and operator of the Kickstarter campaign,…
A quite late Happy New Year 2023 to all of you! Once again with 2022 an eventful year has passed, and Gentoo is still alive and kicking! 2023 already started some time ago and some of us have even already been meeting up and networking at FOSDEM 2023. Still, we are happy to present once…
The Gentoo project has provided a 2022 recap that highlights all of their interesting milestones achieved over the past year for this traditionally source-based Linux distribution that has long been popular with enthusiasts and power users. Gentoo had quite an exciting 2022 with many accomplishments even with not too often generating much media attention for…
Linux 6.1 was widely anticipated to be a Long-Term Support (LTS) kernel with normally the last major release series for the calendar year normally promoted to LTS status. Greg Kroah-Hartman as the Linux stable maintainer went ahead today and formally recognized Linux 6.1 as the 2022 LTS kernel. Greg KH was planning on Linux 6.1…
Summary The Linux kernel does not correctly mitigate SMT attacks, as discovered through a strange pattern in the kernel API using STIBP as a mitigation[1], leaving the process exposed for a short period of time after a syscall. The kernel also does not issue an IBPB immediately during the syscall. The ib_prctl_set [2]function updates the…
Hardware Vendors Hardware vendors upload redistributable firmware to the LVFS site packaged up in an industry-standard .cab archive along with a Linux-specific metadata file. More information » End Users The fwupd daemon allows session software to update device firmware on the local machine. Designed for desktops, it is also usable on phones, tablets and on…
Oracle and Red Hat together on cloud Linux: Believe it or not! No! Really! I think this is something like Tesla partnering with GM to sell Tesla Model S electric cars at GM dealerships. Unbelievable! RHEL is available now on OCI. According to Clay Magouyrk, OCI executive vice president, “Starting today, customers can deploy Red…
Linux distros procedure and lunge the total time, which tends to imply that anything that continues for years has something going for it. Calculate Linux is now not neatly-known within the West but here is the 13th main liberate. Calculate Linux 23 seemed comely three days before the tip of ultimate three hundred and sixty…
