i'm finally running octoprint directly on my prusa mk3s+ via an installed/integrated raspberry pi zero 2 w and octopi. the hardest part was finding and buying the zero 2 w—thankfully they have been showing up in online inventories lately—and the 18mm breakable header. (i also had to hunt down the zero 2 w frame pattern that is a slight remix of the original frame—not linked because there might be some licensing issues in play.)

i didn’t expect something like this to exist but when i found out it did i had to buy one…

It's amazing what will still compile and run. Consider this old project I maintained for a while, a while ago—it still has at least one file of pre-ANSI C (with the K&R style function definitions) alongside a bunch of C and C++ that compiles under C++14.

The story is that this actually runs a service that I needed to migrate from an old CentOS server to a new Ubuntu server. Despite it being a 30+ year old project, and my not having touched my fork in ~5-6 years, it all just compiled and ran (specifically configure && make resulted in a working binary on the new server). I can't think of any other piece of software I use that I have that kind of confidence in just working!

latest project… we got my wife’s parents bikes out of storage where they’d been collecting dust for about 25 years, put new tires on them, tuned them up, cleaned them up and went riding!

@rpilocator great work! i snagged a raspberry pi zero 2 w off adafruit today after catching notice that it was in stock!

whoa! i managed snag a raspberry pi zero 2 w. as fate would have it, i had all necessary prerequisites in place when i noticed availability: 1) existing, verified adafruit account, 2) my wallet and credit card near me. i've lost out on both counts before...

this is the second day i woke to find out they were in stock and are now again out of stock...
