The last two nights I was heads down trying to figure out how to re-engineer the background processes in the forum app, and it's frustrating the hell out of me.
My first problem was just not being able to conceptualize how to design it. I finally stepped back enough from it that last night and I got it distilled to a logical and relatively easy design that required implementation of just one method in the derived service classes.
But where I'm sucking is the multi-threadedness of it. When I upload it into production, the code is firing several times at each interval, and I can't figure out why. It's pissing me off. It looks like I'm following proper singleton patterns, but it's not working.
I just wish I could take time off to really dive into this and get it right. I've spent at least eight hours on it, and it seems like it should be something obvious.
God only knows how desktop app developers deal with threading issues every day.
