As we approach the 10 year anniversary of the 1.0 release of Kubernetes, let's take stock of the successes and failures of the project in the wild. Also what would be on a wish list for a Kubernetes 2.0 release.
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
After years on a VPS, I'm moving my self-hosted services home and using the opportunity to migrate to a more flexible and robust setup.
A blog about making culture. Since 1999.
There's no silver bullet, but if we put some "lead" bullets in the right places, we have a good shot at keeping sensitive data out of logs.
Build reproducibility is often considered as a de facto feature provided by functional package managers like Nix. Although the functional package manager model...
TL;DR : GitHub Actions provides a policy mechanism for limiting the kinds of actions and reusable workflows that can be used within a repository, organization, or entire enterprise. Unfortunately, this mechanism is trivial to bypass . GitHub has told me that they don’t consider this a security issue (I disagree), so…
The Grafana Stack can be an incredible powerful monitoring solution, but through my experience I found out how maintenance intensive it is and how uncertain the…
Any company using Kubernetes eventually starts looking into developing their custom controllers. After all, what’s not to like about being able to provision resources with declarative configuration: Control loops are fun, and Kubebuilder makes...
Redis is arguably the most well regarded tech of all. But many times you do not need Redis. Here are 3 examples from my last 3 jobs.
By default, log based on fixed time intervals rather than number of messages.
Happy New Year! Or so I thought. After a refreshing Christmas vacation with my family, I was stashing something away in our storage room when I noticed the server fan running at maximum speed. This was very unexpected, considering my server is powered by an Intel i3 and should handle all the light tasks I run quite…
Time seems simple. But we engineers lose sleep over something as basic as keeping clocks in sync. Here’s why…

Wolfram releases the Wolfram Compute Services system--a fully programmable, streamlined way to scale up Wolfram Language computations. For large volumes of data, extensive iterations, large-scale parallelism and more.
After 10 years as an AWS customer and open-source contributor, they deleted my account and all data with zero warning. Here's how AWS's 'verification' process became a digital execution, and why you should never trust cloud providers with your only copy of anything.
Since a years we know, or might suspect, our chats are listend on, our uploaded files are sold for advertising or what purpose ever and the chance our social messengers leak our private data is incredibly high. It is about time to work against this.
My attempt to create fast and cheap bulk storage by caching HDDs with SSDs on Linux, using standard lvmcache. Contains an introduction to LVM, RAID, and partitioning.
I wanted to know what third-party code I was using in my GitHub Actions. I was able to use standard text processing tools and shell pipelines to get a quick tally.
“It’s always DNS” is a famous meme among network people. Name resolution is technically quite simple. It’s “just” translating a hostname like jan.wildeboer.net to an IP address. What could possibly go wrong? I am a radical optimist and detail-obsessed knowledge collector, so I decided to find out. As part of my goal…
Now that Joel0 in the TrueNAS community has created a fork of TrueNAS that runs on Arm, I thought I'd give it a spin—on a Raspberry Pi. I currently run an Ampere Arm server in my rack with Linux and ZFS as my primary storage server, and a Raspberry Pi with four SATA SSDs and ZFS as backup replica in my studio. My…
It has been 0 days since the last change to my home server.
Or using lots of little tools to aggressively reject the bots
The state of CI platforms is much stronger than it was just a few years ago. Overall, this is a good thing: access to powerful CI platforms enables software developers and companies to ship more reliable software more frequently, which benefits its users/customers. Centralized CI platforms like GitHub Actions, GitLab…

From my series of "Christian's Home Lab adventures", here's some more things I've recently learned / discovered and figured are worth sharing: NVMe SSDs on a Raspberry PI, ARM64 adventures, more zfs troubles, and some cool tools you should try.
