@npub1w5s…sjnz Hang on, maybe 10GB did exist in the 1st generation line?
"When first introduced, the iPod 1G only existed in a 5 GB version. The 10 GB version was added on March 30, 2002."

@npub1w5s…sjnz Ha! Fair. TBH, it felt high but I didn't verify. Honest eBay sellers! I never had one of the originals. But the original sentiment is still there. That font tho!

Also, can we talk about how good Apple Garamond looks on the back of the original iPod? 😍

New blog post: iPod 3G conversion to SD card and a new battery.
I wanted to document my steps for anyone else that wanted to try this. And you don't need a disk image from the iPod as a starting point.

Ahh it seems the duplicate shared printers disappear when I take down the WiFi interface and only use Ethernet. I guess CUPS is detecting the shared printers back via second interface?

2024-08-04 13:17:57

When using CUPS on RaspPi, is it normal for printers you’ve added and shared to show up again in the printers list as a shared printer? I want it to ignore its own shared printers in the list.
