QEMU 10 open-source machine emulator brings new CPU features, better device support, and performance improvements.

Arch-based CachyOS’s April 2025 update fixes kernel issues, adds OCCT for stress testing, and improves handheld support.

Chrome will keep third-party cookies, a loss for privacy but a win for web ad rivals. After six years of work, Google’s Privacy Sandbox, technology for delivering ads while protecting privacy, looks like dust in the wind.…

With the Linux 6.15 kernel settling down nicely, I’ve been testing out the current Linux Git state on more systems in looking for any performance changes. Unfortunately this week I ran into a large performance regression affecting the Nginx HTTP(S) web server. Here’s a look at that problem currently affecting Linux Git.

Running GenAI models is easy. Scaling them to thousands of users, not so muchHands On You can spin up a chatbot with Llama.cpp or Ollama in minutes, but scaling large language models to handle real workloads – think multiple users, uptime guarantees, and not blowing your GPU budget – is a very different beast.…

The Linux kernel can be configured so that
kernel modules must be signed or

otherwise authenticated to be loaded
into the kernel. Some BPF developers want that to be an option for BPF programs
as well — after all, if those are going to run as part of the kernel,
they should be subject to the same code-signing requirements. Blaise Boscaccy
and Cong Wang presented two different visions for how BPF code signing could
work at the 2025 Linux Storage, Filesystem, Memory-Management, and BPF Summit.

The April 2025 ISO update is out today for CachyOS, the Arch based Linux distribution known for its aggressive out-of-the-box performance on modern hardware…

Mesa’s NVK Vulkan driver had been Vulkan 1.4 conformant for Turing and newer GPUs, but now with Mesa 25.2-devel it’s Vulkan 1.4 conformant going back to Maxwell GPUs. This change is exported to be back-ported to the upcoming Mesa 25.1 release as well for those interested in using this open-source NVIDIA Vulkan driver…

The Userspace
I/O (UIO) subsystem was first added to the kernel by
Hans J. Koch for the 2.6.32 release in 2007. Its purpose is to facilitate
the writing of drivers (mostly) in user space; to that end, it provides
access to a number of resources that user-space code normally cannot touch.
One piece that is missing, though, is DMA addresses. A proposal to
fill that gap from Bastien Curutchet is running into some opposition,
though.

This brief tutorial explains how to perform bulk text replacement in Bash using grep, sed, and xargs commands in Linux.

For those that have been wondering about the Linux support and more details around the Ryzen AI Max 300 “Strix Halo” APUs on Linux, here’s a brief update…

MySQL 9.3 introduces logical user account dumps, improved JavaScript support, and new Group Replication election features.

Coming more than six months after OpenSSL 3.4, the OpenSSL 3.5 release introduces new features like support for server-side QUIC (RFC 9000), support for third-party QUIC stacks (including 0-RTT support), support for PQC algorithms (ML-KEM, ML-DSA and SLH-DSA), and support for central key generation in CMP.

To provide an insight into the quality of software that is available, we have compiled a list of 17 excellent MySQL tools. Hopefully, there will be something of interest for anyone interested in managing MySQL databases with the minimum of fuss.

In this tutorial, we will explain everything about the hosts file in Linux. The purpose of the host file is to map a domain name to its IP address. In this file, we can configure which websites can access the system, how specific hostnames can be resolved, which websites we want to block, etc. In the following paragraphs, we will describe a host file, how to find the host file location in Linux, how it is used, and how to edit it in any Linux operating system.

Editing a host’s files requires root privileges on the server or a user with sudo privileges. This is important because, at the end of the tutorial, we will explain how to edit the host’s file in Linux with real examples. Let’s get started!

Today’s Linux benchmarking at Phoronix is looking at how the Intel Core Ultra 9 285K performance has evolved since its launch last October. Taking the launch-day benchmarks from October with the same hardware, we are revisiting the Intel Arrow Lake performance under Linux today using the newest system BIOS and the newly-released Ubuntu 25.04 for seeing how the performance has evolved roughly over the past half-year.
