One tool that has become absolutely essential to me for note taking and finding information again is a Wiki. A very long time ago, I initially used WOAS, a personal Wiki platform that was basically a local HTML file that could be modified in the browser. It was a nice system, but at some point, … Continue reading Moving on to MediaWiki – Part 1
When SATA SSDs where still in fashion a few years ago, a power-on drive password could be set in BIOS, which was then stored on the drive. While this didn’t encrypt the data, and every notebook manufacturer had its own way to translate what was typed-in to what was stored on the drive, it was … Continue reading NVMe SSD Password Puzzle
In this part, I’d like to muse a bit on Garmin’s pricing of the InReach service for my use-case and the general procedure of sending and receiving messages. While Garmin’s main application for InReach is outdoor communication and tracking in the wilderness, my use-case is to be able to communicate with far away family members … Continue reading When All Else Fails – The Garmin InReach Mini 2 – Part 3: Pricing and Message Handling
In part 3 of my Dockerize-Me series I’ve been looking at how to run several web services on the same server, make them accessible on the same ports (80 for http and 443 for https) and add Letsencrypt TLS certificates for secure communication. This is typically done with a reverse http proxy setup as described … Continue reading Dockerize-Me: Traefik as Reverse-Proxy – Part 6
In the previous episode, I’ve moved a WordPress Blog from the simple installation of part 1 to the more sophisticated reverse proxy setup I have put together in part 3 to demonstrate that containers are ‘portable’ between different servers with little effort. Moving the container also showed that the nginx-gen container recognizes when new containers … Continue reading Dockerize Me – Containers Managing Containers – Part 5
In part 3 of this series we’ve created a reverse proxy setup with Docker containers in the public cloud to serve the content of several web services from independent docker containers with individual domain names. In this episode I’ll test the concept that containerized applications can easily be moved from one host to another.
In part one of my ‘Dockerize Me’ story, I’ve been describing the reasons why I want to learn more about Docker and gave some first tips and tricks how to quickly install it with a few commands on a Debian based server. A first docker-compose project then demonstrated how to quickly spin-up a WordPress container … Continue reading Dockerize Me – Cheat Sheet and Pyramid of Trust – Part 2
In the previous post I ran FFmpeg and Handbrake on the 6 core CPU of my workstation and got a good but still modest 2.5x speedup of the video encoding task compared to running the same operation on notebook. I would have expected at least a 5x speedup and I’m still puzzled why I didn’t … Continue reading Workstation Power at Home – Part 3 – FFmpeg on the GPU
For many years now I’m operating a Prosody XMPP server at home for private messaging between family members and friends. Together with Conversations on Android devices and the Dino App for Linux it’s the perfect solution. There is one client device, however, to which messages sometimes take a couple of minutes to be delivered. Also … Continue reading Carrier Grade NAT Timeouts And How to Configure Your XMPP Server
I can still remember that as a teenager in the 1980s I used a typewriter for school and to document things. This was the time before I got my first home computer and printer after which I don’t think I used the typewriter much if at all anymore and did all of my ‘word processing’ … Continue reading Some Thoughts On The Advent of Word Processing
