Practical Linux tips and tricks – terminal shortcuts, productivity hacks, and configuration tweaks for Ubuntu and other distros.
When you plug in a new drive, set up a fresh partition, or try to remember which disk is mounted where, you need a quick way to see every block device attached to the system. The lsblk command reads information from sysfs and the udev database and prints a tidy tree of disks, partitions, loop…
frp is a fast reverse proxy written in Go that lets a machine behind NAT accept internet traffic through a public server you already control. In this guide, we’ll install frps and frpc, create their TOML configuration files, run both as systemd services, open the required ports with UFW or firewalld, and expose both an…
Atomic distros work differently from the Fedora or Ubuntu install you’re probably used to. Instead of layering individual packages on top of each other, the entire base system ships as one image, and updates land as a whole swap rather than a slow stream of package changes. As a result, you get a system that’s…
Merged earlier this year for Linux 7.1 was extended attributes on sockets support as a feature sought after by the likes of GNOME and systemd for helping with Varlink IPC usage and other purposes. A limitation though of the functionality has been no efficient means for a BPF program to read those user extended attribute…
Just days after opening the Debian-based TUXEDO OS to public testing, TUXEDO Computers shared more details about a key part of its new distribution: how it will maintain the Linux kernel going forward. As we recently reported, the next generation of TUXEDO OS is moving away from Ubuntu and adopting Debian Testing as its permanent…
Fedora 45 has several system-level changes that need testing on real hardware. The first test day up is GNOME 51, starting on 17 August, with more events planned for RPM 6.1, installation media and others. You can participate with a VM for most tests; some hardware-specific testing is more useful on a real machine. Details…
Linux kernel 7.2 has been released, adding cache-aware scheduling, ext4 filesystem performance boosts and a slew of new and improved hardware drivers for laptops and peripherals. A merge widow record was also set during the 9-week development cycle, with more than 2,100 individual contributors involved. AI, obviously, has helped. Commit-crunching by LWN found roughly 5%…
35 Arjun’s Systems Brief: Last week, Phoronix benchmarked Fedora 44 against five other distributions on a Framework Laptop 13 Pro and Fedora finished at the back of the pack. Before you panic and switch distributions, I want to tell you something from years of performance work: the “slow Fedora” headlines are overblown. Fedora ships with…
You attach a new disk to a server, run lsblk , and the drive is there. Then you try to copy a file onto it and nothing works, because there is no path to copy to. The disk is visible to the kernel, but it has no partition, no filesystem, and no place in the…
Proton has launched AI Paper Trail, a free tool that shows people what their AI chatbot conversations reveal about them. It runs on Lumo (partner link), the company’s privacy-focused AI assistant, and works by digging through exported ChatGPT or Claude conversation history. Once you upload your content, the tool starts building a personal report around…
