In the past, I liked buying used notebooks and use them as my day to day workhorses. It felt good from an environmental point of view and they were significantly cheaper compared to new notebooks, particularly when it came to business notebooks like the Lenovo Thinkpad series. But in recent years, prices for used notebooks … Continue reading Running Ubuntu Linux on Bleeding Edge Hardware: Lenovo E14 Gen 4
Recently, Ubuntu 20.04 LTS bumped the Linux kernel version they use from 5.11 to 5.13. While that is generally welcome to support newer hardware, it unfortunately also broke the suspend/resume functionality of my notebook with an AMD Ryzen 7 4750U CPU. Bummer! This seems to be a known problem in the 5.13 kernel line, and … Continue reading The 2 Hour Kernel Compile
In part 5 of this series, I’ve been looking at how companies like Linode, DigitalOcean and Amazon offer managed Kubernetes cluster instances.

In the previous post, I had a look at Guacamole, an open source client-less remote desktop gateway. It’s a cool piece of software and I have already used it with 12 people connecting to the same number of workstations in the cloud. In this setup, the central Guacamole server that I equipped with 8 vCPUs … Continue reading Stress Testing Guacamole

Apart from the wireless network related topics I wrote about in part 1, the year 2020 was certainly the year video conferencing had a breakthrough for many people. As I value my privacy I was not really keen … Continue reading Things That Moved Me in 2020 – Part 2
I’ve been using a tablet on and off for many years now. However, it’s been mostly off as I was mainly using this device type for media consumption, i.e. web browsing, videos, reading ebooks, etc. rather than creating content. Recently, however, I’ve taken another look at tablets with a pen and how they can be … Continue reading Evolving Tablet Use – What’s the Difference Between a 320 vs. a 650 Euro Tablet?
For a long long time I wanted to find out a bit more about the history of Digital Equipment Corporation and its legendary co-founder Ken Olson. I’ve never worked on a DEC machine in my career, but many of their machines are famous, e.g. the PDP-1 and space war, the PDP-8 as the first ‘affordable’ … Continue reading Book Review: The Ultimate Entrepreneur – Ken Olson and DEC
In the previous blog entry, I’ve been looking at a number of different commercial video conferencing solutions and if they offer native Linux support. There are a couple of fabulous products with good Linux support out there that easily support sessions with 15-20 simultaneous video participants. Unfortunately, from a privacy and confidentiality point of view, … Continue reading Jitsi Meet and the Number of Video Participants
