PCIe bifurcation splits one physical PCIe x16 slot into several independent x4 (or x8) logical slots. That lets you fit two to four NVMe drives on one cheap adapter card, often just $20 to $50 for a passive model. Bifurcation is a CPU-level feature, not the job of an extra chip, so each drive gets its own lanes with zero overhead. A Gen4 x4 link delivers around 7 GB/s per drive , the same bandwidth as a standard motherboard M.2 slot. Out of M.2 slots but still have a free x16 PCIe slot? Bifurcation is one of the cheapest ways to add more NVMe storage.

You can run a self-hosted Plausible Analytics instance on a $6/month VPS. It uses Docker Compose and a Caddy reverse proxy for automatic HTTPS. The whole process takes under 30 minutes. Once it runs, you add one <script> tag to your site and you’re done. No cookie banners, no personal data collected. The tracking script weighs under 1 KB gzipped. It stores everything in a ClickHouse database on your own server, and gives you a clean, fast dashboard for your traffic.

The best USB-C docking stations for a dual-monitor Linux setup in 2026 are the CalDigit TS4 (Thunderbolt 4, dual 4K@60Hz, rock-solid kernel 7.0 support) and the Anker 777 (USB4 Gen 2, excellent driver compatibility, more affordable at $149). The deciding factor is whether your laptop supports Thunderbolt 4 or only USB4. Thunderbolt provides guaranteed DisplayPort alt-mode bandwidth for dual 4K; USB4 solutions share that bandwidth with USB traffic and may require Multi-Stream Transport (MST) support from both the dock and the kernel.

Systemd timers should replace cron for nearly every scheduled task on modern Linux. They log to the journal, manage dependencies, and add random delays to avoid resource stampedes. They also catch up on runs missed during a reboot. The one reason to keep cron is legacy support on minimal systems without systemd. If your distro shipped in the last decade, you have everything to switch.

This guide covers the real problems with cron. It explains how systemd timers work and migrates several cron jobs step by step. It also covers the sandboxing and resource controls that make timers a better fit for production.

You have sent the message “it works on my machine” at least once in your career. Maybe you have been on the receiving end of it. Either way, the problem is always the same. Two machines that should be identical are not, and no one can say why. One has Python 3.11, the other has 3.12. One has a system OpenSSL that some C extension links against, and the other does not. One engineer installed a package six months ago and forgot.

PiKVM turns a Raspberry Pi into a full KVM-over-IP device. It gives you IPMI-like remote access to any computer’s BIOS, boot loader, and OS through a web browser. You wire the Pi to the target machine’s HDMI output and USB port. Then you open the PiKVM web page from anywhere on your network. You get live video of the screen, keyboard and mouse control, virtual media mounting, and ATX power control. A DIY build runs under $100 in parts. Even the top PiKVM V4 Plus at about $385 costs far less than IPMI modules from HPE or Dell.
