Around a year ago I scaled back my hardware at home and replaced my Dell R710 with my current host, an OptiPlex 3070 Micro desktop. While that greatly reduced power consumption, I’m starting to reach its limits and would like to try the clustering functionality included with Proxmox. Requirements Minimum of 3 nodes, preferably 4 I’d like to keep the hardware consistent; each node should be as similar as possible. https://ajr.neocities.org/posts/2021-02-05-shelf-mount-stereo/ Thu, 04 Feb 2021 21:24:00 +0000 https://ajr.neocities.org/posts/2021-02-05-shelf-mount-stereo/ A new home with ceiling-mounted speakers throughout the property is quite exciting, right until the point you see pricing for multi-zone amplifiers, or really any amp with more than just a few channels. In the case of my patio there are just 4 speakers, wires terminating in a garage cabinet. Why buy a new amplifier when a spare car stereo has more than enough power to drive 4 ceiling speakers? https://ajr.neocities.org/posts/2015-11-3-werc/ Tue, 03 Nov 2015 00:00:00 +0000 https://ajr.neocities.org/posts/2015-11-3-werc/ Change the Markdown parser used by the Werc rc shell-based web framework For a while now, I’ve been running a few sites on werc, the “sane web anti-framework.” While it’s a very nice, minimal, and visually attractive setup, I’ve run into a few problems, one being the default markdown processor. While there isn’t really a problem with the default markdown rendering script, it lacks several popular features of GitHub’s markdown implementation, which many take for granted. https://ajr.neocities.org/posts/2015-10-21-autossh/ Wed, 21 Oct 2015 00:00:00 +0000 https://ajr.neocities.org/posts/2015-10-21-autossh/ Exposing services using persistent SSH tunnels and Autossh In several years of using unix-like operating systems, I just recently needed to use an SSH tunnel for the first time. I’ve been working with a pfSense appliance in an environment where I couldn’t access the appliance from the outside due to it being on a local area network behind a NAT firewall. Because of the nature of the project, I’m only able to get physical access for a short time each day, which isn’t enough to get anything done.
