While the press and pretty much everybody focuses on ChatGPT these days, there’s another project of the same company that was recently open sourced that promises to create transcripts of video and audio files. It’s called Whisper AI. As I do get audio files every now and then for which a transcript would be helpful, … Continue reading A First Test of Whisper AI
So here we go, it’s 2023 and this blog has once more moved to another host. Initially started as a blog on Typepad in 2005, it has so far moved to a hosted server platform on which I installed WordPress (2016), to a virtual machine I could administer on my own (2018), and then, two … Continue reading Moving the Blog to ANOTHER Virtual Machine
Another crazy year, both good and bad in so many ways, is coming to an end, so here I go with time honored tradition of looking back to what moved me this year in tech! In The Wireless Domain Obviously, there’s been a lot going on in the wireless domain again. While some parts of … Continue reading Things That Moved Me in 2022
Normally, I’d say that raw computing power should be in the cloud, or perhaps under my desk, but definitely not in my backpack. That’s because computing power comes at a price: The notebook gets heavier, battery life becomes shorter and the power supply that has to supply at least 120 Watts of power is a … Continue reading Running Ubuntu Linux on Bleeding Edge Hardware: Dell Notebook with an Intel 12800H and an Nvidia GPU
When I recently read this article about vulnerabilities to break out of virtual machines, I became aware again of the concept to run virtual machines inside virtual machines. This is also called nested virtualization and it seems most modern Intel and AMD CPUs support this feature. But does it really work ‘just like that and … Continue reading Nested Virtualization
Wow, this is part 10 in my series on how to get started with Kubernetes! I am obviously having a lot of fun with the topic, and it’s really nice to be able to experiment with the technology, as it is not only the basis for 5G core networks, but massively transforms all parts of … Continue reading Kubernetes Intro – Part 10 – Persistent Storage in a Managed Cluster
Yes, this is already part 6 of my ongoing Kubernetes intro series. In part 5, I have moved ever deeper into the cloud by looking at how to create managed Kubernetes clusters in Amazon’s and Linode’s clouds. Containers and Kubernetes are all about scale, so one might wake up one day with many Kubernetes clusters … Continue reading Kubernetes Intro – Part 6 – Managing All Those Clusters
When most people talk about virtual machines, they mean Linux based VMs in the cloud. But there’s much more that can be done with the technology. Before turning to the cloud, I’ve actually started using virtual machines many years ago on my Linux desktop to have access to a Windows environment to run a number … Continue reading Taming Windows in a Virtual Machine
After exploring many new technical topics over the past few months, including Docker and Kubernetes, I ventured out over the weekend to have a look at OpenStack. I wanted to have a closer look because OpenStack is used to provide a private cloud infrastructure, i.e. virtual machines (compute), storage, and networking for many projects. OpenStack … Continue reading Playing with OpenStack – A Rather Unpleasant Experience
As you might have noticed on the blog, I’ve been doing a lot of hands-on exploration these days of bare metal hardware, virtual machines, containers and orchestration (e.g. Kubernetes). My motivation behind this is twofold. For one thing, I like to evolve my private cloud. Current status: 25 containers are now running in my private … Continue reading The Three Eras Of Telecom Infrastructure Hardware
