At my place of work, we have a client relationship to a company like ours in a neighbouring country. They develop a software that is of much use to us so we pay a license to them for it. They are nice people but god damnit, there is one thing they just never got right. They only support one platform, one that is certified UNIX, yet no matter how severe an error, their cli tools and scripts exit with 0 no matter what. I'm the guy who writes some smaller tools and scripts on our side integrating with their software so you probably understand why I get a bit upset about this at times. Still, I enjoy my work and as I said they are nice people and also they are a quite small team so I don't want to burden them with these concerns when there are other things that our company need from them more. Anyway, I've been with my company for a few years and soon my contract expires and I'm going to study the field our company is in and get a degree in that, then I'm going to apply for a position doing our core business. I would still like to be involved with the software my current position is touching on, though, if possible. (Our company has 1000+ employees and several different sub-sections, so even though I might get back into the company, it's not a given that I'll be working with the group of people I am now even though I'd like to.) I also sometimes think that if possible, perhaps I'd like to work for that other company in our neighbouring country for a few years and be on the dev team of the software. After all, I have experience from the user side which the dev team has not and the dev team has seen some of the tools I've made and a couple of the guys seemed to think that some of that stuff was pretty decent.
