Minor Blog Extensions First I added asciinema support to better show some console stuff. ASCIInema allows to record a terminal session in text and replay it as text. So no wasteful GIF or blurry MP4 for just text. You can see the first use of it in this blog in my FZF SSH Parser Article. Then inspired by Naty I also implemented humans.txt [?] and human.json [?] standards to this blog. Im not so big in all the Indieweb standards. But specially in times of AI slob everywhere, it cant hurt to have more humans on the web. ...

What it does… As said, fzf is my go to for great shell search and tui’s. Basically add a fuzzy search to everyting you can imagine. But this is not what I want to write about, today I want to show another usecase of fzf in combination with my fish shell. I start using fzf as a SSH config tui. It allows me to type ssh + space and the basically type any hostname or alias from within my .ssh/config to autocomplete and search using up down. See the recording: ...

Not an lenghy Article, just posting my findings for whoever may need it. The Hardware: i-tec USB-C 4K Metall Nano Docking Station Named by the bulky name i-tec USB-C 4K Metall Nano Docking Station 1x HDMI 1x GLAN 3x USB 3.0 1x SD/MicroSD 1x Audio Power Delivery 100W I found mine on Amazon. Port-wise, it has what I need. Mostly I use this kind of light dock if I work remotely or at events to attach one screen, network, mouse and have it charging my laptop. So I can quickly grab it when I need to go somewhere. ...

signal on Linux offer the way to store your encryption key in your system walled (encrypted) or local as plain-text unencrypted. Actually if you use a full disk encryption a clean text key isn’t a huge issue. But nevertheless to give it a bit more secure feeling I wanted to use KWalletD to store the signal key encrypted. Signal now even prompt you with a question if you want to do so or not. So easy I thought, quickly enabled it; But to verify I took a look at the logfile and found; It is actually trying to use kwallt6 but can’t. ...

Currently I use as my productivity working device a Tuxedo Laptop, the Infinity book pro 14". It is about 1.5yrs old and started acting up in december when it comes to battery. The Battery sometimes was overnight discharging to 0% even the laptop was powered off. Also it showed a reduced maximal capacity. In Linux you can check your battery stats quickly with upower -b the old battery looked like this: ...

Recently we had the Digital Independence Day what better Reason could one have to rethink how I use published photos. I actually wanted to integrate them better into my blog already since long. But Digital Independence Day was a good kick in the ass to finally quit Instagram for real. I’m not here to start a big moral talk… let’s focus on the Tech Aspects of what I did. As you may noted we now have the new Menu entry /photos which offers a small Gallery. Instead of integrating another workflow which is doomed to fail because of my lazyness, I need something easy usable from my Android phone. So I had my pixelfed account laying there, mostly collecting dust. Why not start using it again and integrate it into the blog. This post is about how I wired this up. ...

My Setup and the Problem I use Linux on my main work laptop, where remote access is effortless: I can SSH with Kitty’s remote edit kitten or mount remotes via KDE Dolphin. But at home, my desktop runs Windows 11 for gaming (thanks to stupid anti-cheat restrictions). I normally just game on the desktop; but sometimes I have to do some work from the Desktop, already at the desk and need to quickly edit stuff remote. Most time I just used scp. But remembering in the past as win user, I used WinSCP for remote file editing. Found out quicky it natively refuses to connect using my SSH key from the already running agent in 1password. ...

Got one Ubiquiti Unifi 10G Ethernet Adapter, model UACC-Adapter-RJ45-USBC-10GE. In the past, I’ve mostly got StarTech adapters for 10G Copper, but right now they’re either sold out or going for double the price. The Unifi 10G is 150€ plus tax, it fits what I need. First off, it plugged right in on my Linux laptop running kernel 6.14 and a MacBook Air. No fuss with drivers or anything. Here’s what the kernel spit out on Linux: ...

Today, a small blog post about a real-world headache I had with Fedora and public WiFi hotspots in hotels or venues. If you work remotely a lot like me, you find yourself hopping from Wi-Fi to Wi-Fi: hotels, airports, event locations; basically anywhere but your regular desk. Connect to Wi-Fi, get dumped onto a portal page, accept the policy (or sign in), and only then can you actually get online. ...
