Zathura is a fantastic PDF viewer. It also supports Postscript, DjVu, and Comicbook archive. In particular it supports using mupdf for the backend, so it’s rather fast (unlike poppler, used by evince and friends). Here is a screenshot of Zathura:

Now that I’ve introduced Zathura. I want to talk about a problem I had recently. I wanted to print a document a couple weeks ago, but found whenever I issued a :print command in Zathura, the program would crash.

During these interesting times, I figure it would be a good idea to describe how I’ve been keeping myself busy, bugs I’ve fixed, and some of the daily tasks/routines that keep my day structured.
For context: I moved house on the weekend of March 21st, which is a couple weeks before the Covid-19 fiasco became a front-and-center concern for my geographical region. I am finishing my undergrad in computer science — this is my last semester.

I recently moved, and my new abode has an Ubiquiti Amplifi LAN. The rationale is this mesh-based WiFi network eliminates the need to install Ethernet between Wireless Access Points (APs). It works surprisingly well. In this post I document how I extended this network so I could place my networked devices all on the same Ethernet segment, without needing to wire it to the Amplifi base station.
The idea is the network should look like this:

Previously I detailed how I set up blog.winny.tech using GitHub for source code hosting and Caddy’s git plugin for deployment. This works well and I used a similar setup with my homepage. The downside is I host the static web content and I am tied to using Caddy.1 I imagine simpler is better, so I opted to host my static sites — https://winny.tech/ & https://blog.winny.tech/ — with GitLab pages.
What’s wrong with Caddy?

Most of my workstations & laptops require a passphrase typed in to open the encrypted root filesystem. So my steps to booting are as follows:
Power on machine Wait for FDE passphrase prompt Type in FDE passphrase Wait for boot to complete and automatic XFCE session to start Since I need to know when the computer is ready to accept the passphrase, it is important the framebuffer is usable during the early part of the boot.

About a fortnight ago (Nov 9th) I went to the MSOE x Google Cloud hackathon.1 There was pizza, soda, and Google Cloud gear. Each group was given a Google AIY Computer Vision kit to assemble, and build a proof of concept around.
The kit contained a Raspberry Pi Zero W, the Raspberry Pi Camera Add-on, a breakout board to provide simplified pin-outs for a button with an integrated light, an additional LED that mounted next to the camera to indicate if the camera was active, and a piezo buzzer.
