Yet Another Job

Wait, what?!? I know, I know, it seems like I’ve been changing jobs a lot lately. So much so that I haven’t even written posts about some of them. Note: This has always been one of my favorite New Yorker cartoons from way back in the day when I lived in NYC. In the 1980s, this was a real phenomenon on the Upper West Side. It’s been a very difficult time for the industry, for DevRel in particular, and for me individually.

How to avoid bricking your raspberry pi during updates

Having an update brick (render inoperable) your device is a real risk, and even the largest of companies have been known to have it happen. This has just happened to Apple (Apple pauses iPadOS 18 rollout for M4 iPad Pro after bricking complaints) and I think we’re all well aware of the Crowdstrike incident by now. It’s such an issue that, given the recent disasters with update rollouts (which I wrote about briefly here) it seemed like a good topic to dive into.
