Practical Linux tips and tricks – terminal shortcuts, productivity hacks, and configuration tweaks for Ubuntu and other distros.
5 Marcus’s DevOps Brief: Every sysadmin hits the wall at some point. A runaway process eats all your RAM, the OOM killer fires, and your database goes down at 3 AM. I have been that sysadmin. This guide covers the three resource control mechanisms every Linux administrator needs: ulimit for session limits, systemd for service-level…
Disks rarely die without warning. Long before a drive stops responding, it usually accumulates reallocated sectors, read errors, or climbing temperatures, and the drive itself keeps count through SMART (Self-Monitoring, Analysis and Reporting Technology). The smartctl command reads those counters, so the question “is this disk failing?” gets an answer based on the drive’s own…
Ever tried a DAS (Direct-Attached Storage) device? Unlike NAS, where you have a bunch of hard drives available over network, DAS is directly connected to your computer. I never used such a product because I never had the need. But then Orico sent me there new DAS 88 Series 4-Bay USB4 NVMe SSD Enclosure and…

Canonical has brought Livepatch to Arm64 devices for the first time, allowing Ubuntu systems on Arm hardware to apply critical kernel security patches without a full reboot. Livepatch is one of Ubuntu’s best hidden security features – it’s not enabled by default, requires Ubuntu Pro – as it allows kernel security updates to be applied in…
240 Sarah’s Security Brief: I have spent the last three years building isolated penetration testing labs for clients who needed to simulate real network conditions without exposing production infrastructure. WireGuard gave me the protocol, but managing keys and peers manually does not scale beyond a handful of devices. That is exactly why Tailscale matters. It…
When you want to train models, compile GPU code, or run local AI tools on Ubuntu, the NVIDIA driver alone is not always enough. Development tools and many build workflows also need the NVIDIA CUDA Toolkit, which provides the nvcc compiler, CUDA libraries, profiling tools, and headers used by PyTorch, TensorFlow, llama.cpp, ComfyUI, and other…
For years, I never gave GNU coreutils much thought. They’re the standard Linux commands like ls, cp, mv, cat, sort, and wc that come with almost every Linux system.
