RAM Upgrade on a Synology ds920+

There are a lot of threads on unofficial RAM upgrades that work or don’t work on the Synology ds920+. Just for context, the Synology ds920+ comes built in with 4GB RAM soldered in and has one expansion slot. The official maximum is 8GB, and Synology sells an official 4GB RAM stick (model: D4NESO-2666-4G) for this. However, there are many anecdotal reports that adding 8GB and 16GB RAM also work. By running a handful of applications and Docker containers, I was maxing out the built in 4GB of RAM and spilling into swap space which slowed down the entire NAS to Continue Reading

Setting up IPv6 with Telus PureFibre on a Ubiquiti UniFi Dream Machine

I recently got a Ubiquiti UniFi Dream Machine (UDM) to support gigabit-speed internet at my new apartment. The UniFi line is a significant step up from consumer home routers, providing better customizability and management options for networks. The following settings are required to get IPv6 working locally using Telus PureFibre internet: In the Network application, go to Settings -> Internet -> WAN. Expand the Advanced section, then expand the IPv6 Connection subsection. Set the following settings: IPv6 Connection: DHCPv6 Prefix Delegation Size: 56 Apply the changes at the bottom. Then go to the Networks section and open your LAN network. Continue Reading

Handling power outages with an uninterruptible power supply and NUT

The main reason for having a UPS is to protect against data loss due to power outages whether it be unsaved work, or corruption due to the computer not having enough time to write things to disk. I only really started to take this seriously when I got my Synology networked attached storage (NAS) which holds all my data. The UPS I chose is an APC model with 1300VA and a USB connection, which is powerful enough to power most of the critical equipment I have at home and to ensure they have enough time to shut down. One of Continue Reading

Fixing missing categories and tags in WordPress’ block editor

For several months now, I’ve noticed that the Categories and Tags widgets were missing in my WordPress’s post block editor. It was sort of fine because I could work around it by assigning categories and tags through the Quick Edit functionality from the post list, but it was an annoyance. I had done the usual debugging steps of disabling plugins, changing to the default theme, even reinstalling the core WordPress code, but nothing changed. I had tried searching online for phrases like “wordpress categories and tags missing” but didn’t come up with anything. Today, I found two clues that led Continue Reading

Desktop computer v2

I’ve been wanting to build a new PC for a while. My current PC was originally built back in 2012, and upgraded in 2018. There’s still a lot of life left in this PC, so it will definitely be repurposed. However, for desktop use, it has fallen short in being unable to run a few modern applications (ok, also games) that I’ve been interested in, namely: DaVinci Resolve, the 2020 version of Microsoft Flight Simulator, and Call of Duty: Warzone. Spending a lot more time at home due to the pandemic also drove my decision to upgrade the PC. But Continue Reading
