+### Bookworm Upgrades
+
+I upgraded several more systems to [Bookworm][], including a [Raspberry
+Pi 4 Model B 4GB][pi4] and a [Raspberry Pi Zero W][pi0w].
+
+All of the upgrades have gone smoothly **except** for the [Pi Zero
+W][pi0w], which failed with "Illegal instruction" errors during
+`dist-upgrade` and left the system unbootable in two separate upgrade
+attempts.
+
+### PNG Compressors
+
+I tried the following [PNG][] compressors on a set of several
+dozen screenshots:
+
+* [pngcrush][]: Lossless PNG compression command-line tool.
+* [optipng][]: Lossless multi-format image compression command-line tool.
+* [pngquant][]: Lossy PNG compression command-line tool and library.
+
+[pngquant][] produced the smallest output images.  The results were also
+visually indistinguishable from the source images, at least for my use
+case.  Of the two lossless encoders, [optipng][] produced marginally
+smaller images than [pngcrush][].
+
+(The bitmap images on this site are served as lossless [WebPs][webp]
+with [PNG][] as a fallback, courtesy of the [`<picture>`
+element][picture]).
+
+### Domain Registrar
+
+I've been considering switching to another [domain registrar][] for
+a few years.  The [recent .zip TLD tizzy][zip-tizzy] seemed like a
+perfect opportunity to register a new domain through a different
+[registrar][domain registrar].  I'd heard good things about
+[Namecheap][], so I created an account and registered my shiny new
+`.zip` domain: [fdsa.zip][fdsa.zip].
+
+Thoughts on [Namecheap][] so far:
+
+- Good prices.
+- Fast and simple interface.  Account setup and domain registration
+  only took a few minutes.
+- [2FA][] prominently located and easy to enable.
+- They haven't sold, lost, or spammed my email address (yet).
+- DNS propagation only took 2 hours.
+
+My next step will be to migrate several secondary domains from
+[GoDaddy][] to [Namecheap][].
