My favorite internet service provider, init7, is rolling out faster speeds with their infrastructure upgrade. Last week, the point of presence (POP) that my apartment’s fiber connection terminates in was upgraded, so now I am enjoying a 25 Gbit/s fiber internet connection!
init7 recently announced that with their FTTH fiber offering Fiber7, they will now sell and connect you with 25 Gbit/s (Fiber7-X2) or 10 Gbit/s (Fiber7-X) fiber optics, if you want more than 1 Gbit/s. While this offer will only become available at my location late this year (or possibly later due to the supply chain…
The Intel 285K CPU in my high-end 2025 Linux PC died again! 😡 Notably, this was the replacement CPU for the original 285K that died in March, and after reading through the reviews of Intel CPUs on my electronics store of choice, many of which (!) mention CPU replacements, I am getting the impression that Intel’s…
Motivation Despite using a FTTH internet connection since 2014, aside from the one fiber uplink, I had always used network gear with 1 Gbit/s links over regular old rj45 cat5(e) cables. I liked the simplicity and uniformity of that setup, but decided it’s time to add at least one fiber connection, to get rid of a…
I have been using a MacBook Pro M4 as my portable computer for the last half a year and wanted to share a few short impressions. As always, I am not a professional laptop reviewer, so in this article you won’t find benchmarks, just subjective thoughts!
For the last 10 years, I have been interested in hi-DPI monitors, and recently I read about an interesting new monitor: Dell’s 32-inch 6K monitor (U3224KBA), a productivity monitor that offers plenty of modern connectivity options like DisplayPort 2, HDMI 2 and Thunderbolt 4.
I was pleasantly surprised by how easy it was to make it possible to push a PC’s power button remotely via MQTT by wiring up an ESP32 microcontroller, a MOSFET, a resistor, and a few jumper wires. While a commercial solution like IPMI offers many more features like remote serial, or remote image mounting, this DIY…
For over 10 years now, I run two self-built NAS (Network Storage) devices which serve media (currently via Jellyfin) and run daily backups of all my PCs and servers. In this article, I describe my goals, which hardware I picked for my new build (and why) and how I set it up.
