When talking about backup solutions, on Linux we are spoiled for choice: in the previous tutorials, for example, we talked about creating encrypted and efficient backups with Borg and Restic. Kopia is another free and open source alternative to those applications: it is written in Go, and it is able to create secure backups, both to local filesystems and to cloud-based storage services like Amazon S3, Azure Blob Storage, Backblaze B2 and Google Cloud Storage. Unlike Borg and Restic, Kopia comes also with an officially supported GUI interface: KopiaUI.

Earlier this month Canonical announced Ubuntu Linux support for the Orange Pi RV2 as a low-cost RISC-V developer board. The Orange Pi RV2 with eight RISC-V cores and 8GB of RAM costs just around $64 USD. The price point and specs were interesting that I ordered one and have been running performance benchmarks on it since for seeing how capable this is as finally an interesting, low-cost and readily available RISC-V board.

The Docker pull command is one of the essential commands that allows users to download container images from a registry to their local machine. This command is often the first step in the container deployment workflow, enabling developers to retrieve pre-built images before running containers. As part of the core set of Docker basic commands, understanding how to effectively use the docker pull command is essential for anyone working with containerized applications.

Following a lot of work in this direction toward the end goal of removing GNOME X11 support, this milestone may finally be acheived for the Fedora 43 cycle due out by the end of the year. A change proposal has been filed for removing the GNOME X11 packages in the repository and in turn making the GNOME desktop Wayland-only on Fedora Linux...

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

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.

The open-source QEMU 10.0 machine emulator and virtualization software has been released as a major update that brings many new features and various improvements for next-generation emulation.

Running GenAI models is easy. Scaling them to thousands of users, not so much Hands 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.…

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.

Starting August 15, 2025, Steam will no longer work on Linux systems using glibc older than version 2.31.

Last year a patch was raised for the Linux kernel that would report outdated CPU microcode versions as a security vulnerability. With Intel routinely issuing new CPU microcode updates for security vulnerabilities and addressing other functional issues, the Linux kernel would begin warning users when recognizing that outdated CPU microcode is deployed for a given processor. That patch has now been queued into a tip/tip.git branch and thus looking like it will be submitted for the upcoming Linux 6.16 kernel cycle...

MicroPython has reached a major milestone with the release of version 1.25.0, delivering significant enhancements after over three years of development. This update introduces the long-anticipated ROMFS (Read-Only Memory File System), new processor support, TLS improvements, and expanded board compatibility across multiple architectures. One of the most notable additions is ROMFS, a read-only, memory-mappable, extensible […]

Merged last year in Linux 6.11 was getrandom() support in the vDSO for x86/x86_64 and then in Linux 6.12 was extended to LoongArch and ARM64. With the upcoming Linux 6.16 cycle, this support for faster while still secure RNG for user-space is set to come to RISC-V...
