Linux Swap Table Code Shows The Potential For Huge Performance Gains

Following recent discussions by Linux kernel developers around integrating swap cache and swap maps functionality with the swap allocator, Swap Table was born. With Swap Tables the hope is for lower memory use, higher performance, dynamic swap allocation and growth, greater extensibility, and other improvements over the existing swap code within the Linux kernel…

How to Install Odoo 18 on AlmaLinux 10

Odoo, which was previously called OpenERP, is a comprehensive suite of open-source business applications. It is a popular open-source enterprise resource planning (ERP) software choice. Odoo includes many modules that can be integrated into one application, enhancing its appeal. The newest version, Odoo 17, offers new features that boost its ease of use. The redesigned interface now supports keyboard shortcuts, facilitating the selection of records and enabling multiple selections with ease. This tutorial will show you how to install Odoo 18 on AlmaLinux 10 with nginx or Apache as a reverse proxy.

Intel Core Ultra 7 256V “Lunar Lake” Linux Performance In Mid-2025 vs. Launch Day

Given the significant gains to the Intel Arrow Lake performance on Linux since launch that I showcased last month on Phoronix, I was also eager to see how the Intel Lunar Lake performance has evolved since its debut last year. In this article is a look at those relatively weak launch-day Linux performance numbers for the Core Ultra 7 256V compared to where they are performing now on Ubuntu 25.04 for showing how far the Intel Lunar Lake performance has evolved since last September.

[$] A new DMA-mapping API

Leon Romanovsky began his session at the 2025 Linux Storage, Filesystem,
Memory Management, and BPF Summit (LSFMM+BPF) by explaining that the improved DMA-mapping API that he has been
working on is a group effort. He, Chaitanya Kulkarni, Christoph Hellwig,
Jason Gunthorpe, and others are proposing to modernize the API and to
“make it more suitable for current kernels“. He told the assembled
storage and filesystem developers that the progress on the proposal has
stalled, but that it was the basis for further work in various areas, so he
hoped to find a way to move forward with it.

Oniux: kernel-level Tor isolation for Linux applications

The Tor project has announced
the oniux utility which provides Tor network isolation, using Linux
namespaces, for third-party applications.

Namespaces are a powerful feature that gives us the ability to
isolate Tor network access of an arbitrary application. We put each
application in a network namespace that doesn’t provide access to
system-wide network interfaces (such as eth0), and instead provides a
custom network interface onion0.

This allows us to isolate an arbitrary application over Tor in the
most secure way possible software-wise, namely by relying on a
security primitive offered by the operating system kernel. Unlike
SOCKS, the application cannot accidentally leak data by failing to
make some connection via the configured SOCKS, which may happen due to
a mistake by the developer.

The Tor project cautions that oniux is considered experimental as
the software it depends on, such as Arti and
onionmasq,
are still new.

How to Create Decoy File System in Linux Using FUSE

A decoy filesystem is a virtual system masquerading as a real filesystem that looks like the real thing but is actually fake. Its purpose is to deceive intruders, observe attack behavior, or induce attackers to reveal their identity.

You can think of it as a “digital trap”. It can lure malicious actors into opening it.

Intel Xeon 6 CPUs make their name in AI, HPC

There isn’t a datacenter workload whose performance or efficiency isn’t improved by using Xeon 6 chipsPartner content IT environments today have a passing resemblance to those from 15 or 20 years ago, when enterprise workloads mostly ran on industry standard servers connected through networks and into storage systems that were all contained within the four walls of a datacenter, where performance as the name of the game and was protected by a perimeter of security designed to keep the bad guys out. …
