### 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.
I don't know if this is a pre-release issue with [Bookworm][] or if this
particular [Pi Zero W][pi0w] is starting to fail. In either case, be
sure to back up your SD card before trying to upgrade a [Pi Zero
Ws][pi0w] to [Bookworm][].
### 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][].
**Update (2023-06-13):** Last night I followed [these
instructions][transfer] to migrate 7 secondary domains. This afternoon
I migrated the remaining 6 domains.
If you disable locking, disable domain protection, and manually approve
pending transfers, the entire process takes about an hour.
