What happens when pacman fails when you’re trying to
recover from uninstalling a package that pacman needs?
1023 % sudo pacman -Syu

pacman: error while loading shared libraries: libicuuc.so.78: cannot open shared object file: No such file or directory
I ran pacman -Syu on my Bosgame brand “Ecolite Series” E2 mini-PC,
as one does on the weekend.
I got a very strange message upon rebooting:
symbol grub_is_using_legacy_shim_lock_protocol not found

I recently got a Bosgame brand “Ecolite Series” E2 mini-PC.
I try to avoid buying from Amazon, but it was steeply discounted.
I put Debian 12 on it initially,
but something about the Debian screensaver or inactivity detector
caused the mini-PC to be unable to wake up.
So I put Arch Linux on it.
That solved the unable-to-wake-up problem,
but during boot, the E2 stopped at the grub> prompt.
My house has 2 CenturyLink fiber optic connections to The Internet. On July 5, 2025, the connections didn’t work for 3 periods of time.
I made two NTP servers using Raspberry Pi single-board computers and GPS receivers.
The resulting NTP servers seem to work well.
A couple of years ago, I made an attempt to create a NTP server using a GPS receiver. I failed.
I tried again in 2025, this time I succeeded.
In January 2025, I started monitoring my network with Smokeping.
I had previously noticed increased latency when a Velop router was connected via powerline ethernet. After upgrading it to OpenWrt, I put that particular Velop back on my network via a $20 TP-Link 8 port 1GbE router. I saw a much smaller increase in latency using the router versus a direct cabled connection.
Matt Sayar investigated how often his home’s IP address changed. I did the same, inspired by him. Thanks, Matt!
While exploring how to configure multiple WiFi access points, routing IP subnets, WAP bridging and the consequences, I noticed that when I switched my laptop from one WiFi access point to another, the NTP configuration stayed the same.
I finally figured out how to get dhcpcd to set the NTP server for a given WiFi access point.
