Debugging and profiling are critical skills in a developer's toolbox, especially when working with low-level system applications. Whether you're tracking down a segmentation fault in a C program or understanding why a daemon fails silently, mastering tools like GDB (GNU Debugger) and strace can dramatically improve your efficiency and understanding of program behavior.

Mesa has supported on-disk shader cache for years to help speed-up game load times and overall system efficiencies. They had shifted from a multi-file cache layout to a single file cache for greater space savings. Steam also added support for the single-file cache. But now upstream Mesa is shifting back from the single-file cache default to the multi-file cache over performance issues...

Though both are capable of managing packages effectively, they have unique characteristics that make them better suited to different use cases.

At the end of last year the upstreaming efforts began for a Raspberry Pi HEVC decoder driver for getting H.265/HEVC accelerated decode working on the Raspberry Pi 4 and Raspberry Pi 5 single-board computers with the mainline kernel. Nearly a half-year later that effort is still ongoing but yesterday brought the third iteration of this driver...

Have you ever asked yourself, ‘What is my server address?’ This post explains the ins and outs of server IP addresses, their importance, and usage on a Linux-based OS. Every server or computer connected to the Internet has an IP address. Even machines without Internet connections possess local IP addresses.

The term “service mesh” has been widely used over the last several years to refer to technology that helps to manage communications across microservices and applications. In the cloud-native world, arguably the first implementation of a service mesh came from Buoyant with the open-source Linkerd technology in 2015. Over the last 10 years, Linkerd has grown as a core project within the Cloud Native Computing Foundation (CNCF). Today the project is out with Linkerd 2.18, continuing the technology’s decade-long evolution with improvements focused on operational simplicity and real-world production scenarios.

Back in March some ideas were talked about by Canonical engineers for Ubuntu Linux to move to Rust Coreutils and other Rust-written system components. Some of this is likely to materialize for the Ubuntu 25.10 release due out in October to allow for sufficient testing ahead of the all important Ubuntu 26.04 LTS release next year. Today the more solidified plans have been laid out for moving to the Rust Coreutils as a replacement to GNU Coreutils with Ubuntu 25.10...

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.
