    Tailscale golink: Private Shortlinks for your Tailnet

    I've shared in the past about how I use custom search engines in Chrome as quick web shortcuts. And I may have mentioned my love for Tailscale a time or two as well. Well I recently learned of a way to combine these two passions: Tailscale golink. The golink announcement post on the Tailscale blog offers a great …

    K8s on vSphere: Building a Kubernetes Node Template With Packer

    I've been leveraging the open-source Tanzu Community Edition Kubernetes distribution for a little while now, both in my home lab and at work, so I was disappointed to learn that VMware was abandoning the project. TCE had been a pretty good fit for my needs, and now I needed to search for a replacement. VMware is …

    Active Directory authentication in Tanzu Community Edition

    Not long ago, I deployed a Tanzu Community Edition Kubernetes cluster in my homelab, and then I fumbled through figuring out how to log into it from a different device than the one I'd used for deploying the cluster from the tanzu cli. That setup works great for playing with Kubernetes in my homelab but I'd love to do …

    Nessus Essentials on Tanzu Community Edition

    Now that VMware has released vCenter 7.0U3c to resolve the Log4Shell vulnerabilities I thought it might be fun to run a security scan against the upgraded VCSA in my homelab to see how it looks. Of course, I don't actually have a security scanner in that environment so I'll need to deploy one. I start off by heading to …

    VMware Tanzu Community Edition Kubernetes Platform in a Homelab

    Back in October, VMware announced Tanzu Community Edition as way to provide "a full-featured, easy-to-manage Kubernetes platform that’s perfect for users and learners alike." TCE bundles a bunch of open-source components together in a modular, "batteries included but swappable" way: I've been …

    Snikket Private XMPP Chat on Oracle Cloud Free Tier

    Non-technical users deserve private communications, too. I shared a few months back about the steps I took to deploy my own Matrix homeserver instance, and I've happily been using the Element client for secure end-to-end encrypted chats with a small group of my technically-inclined friends. Being able to have private …

    Federated Matrix Server (Synapse) on Oracle Cloud's Free Tier

    I've heard a lot lately about how generous Oracle Cloud's free tier is, particularly when compared with the free offerings from other public cloud providers. Signing up for an account was fairly straight-forward, though I did have to wait a few hours for an actual human to call me on an actual telephone to verify my …

    AdGuard Home in Docker on Photon OS

    I was recently introduced to AdGuard Home by way of its very slick Home Assistant Add-On. Compared to the relatively-complicated Pi-hole setup that I had implemented several months back, AdGuard Home was much simpler to deploy (particularly since I basically just had to click the "Install" button from the …

    Setting up Linux on a new Lenovo Chromebook Duet (bonus arm64 complications!)

    I've written in the past about the Linux setup I've been using on my Pixel Slate. My Slate's keyboard stopped working over the weekend, though, and there don't seem to be any replacements (either Google or Brydge) to be found. And then I saw that Walmart had the 64GB Lenovo Chromebook Duet temporarily marked down to a …

    Docker on Windows 10 with WSL2

    Microsoft's Windows Subsystem for Linux (WSL) 2 was recently updated to bring support for less-bleeding-edge Windows 10 versions (like 1903 and 1909). WSL2 is a big improvement over the first iteration (particularly with better Docker support) so I was really looking forward to getting WSL2 loaded up on my work laptop. …
