I spent the weekend trying things that didn’t really work. Well, some stuff kinda worked but not as well as I had hoped.

Feeling way better today now that the 2nd shot vaccine side effects have apparently wore off. I wonder if they will find ways to improve future versions to fix that? I suspect the way these vaccines work is going to totally change medicine in the long run. Reprogramming your own cells to make the drugs you need is genius and feels like it’s one step closer to a true medical tricorder where the doc programs up the prescription and injects.

Earlier this week I tweeted about Core Data crash reports that I haven't been able to figure out. In fact, almost all of Twitterrific's reports were from Core Data. I assumed I was doing something wrong somehow but didn't know how to figure it out since I couldn't reproduce it. These crash reports have been plaguing me for a long time. Years, probably. I've come to mostly ignore them assuming there was nothing I could do about them. I've asked a few times on Twitter and Googled a bit over that time, but nothing ever turned up.

I may have figured out our auto-renewing subscription problem with Twitterrific. This should probably be a blog post, but I don’t want to commit to it being fixed yet - however I want to describe what I found in case it helps anyone or brings anything else to light. Lucky you! Twitterrific implements client-side receipt validation - which is hard. Server-side looks like it's probably easier to deal with, but at the time this seemed to make more sense and we've just kind of stuck with it over the years.
