So last week was the users' conference, during which a whole bunch of people got together in a hotel in some other state and did demos and training of a whole bunch of projects, including the one I work on. I had a great time, mostly because I didn't go, but also because a whole lot of people were at the conference and thus unavailable to bug me.
Even better, of the three remaining developers who were theoretically at work with me, one was sick and going on vacation, one was merely sick, and the third is so quiet I honestly had to stand up and look to see if he was even there. (He was.) Taken all together, that led to some fairly productive time, and I finally found the source of a problem in our product that has been plaguing me for months.
Naturally I sent Rvan email at about 9pm with the subject "The users should go away more often..." and then followed it with information about the bug and what was triggering it. I wasn't even thinking about the fact that Rvan would be projecting the contents of his laptop screen during his presentations the next day.
Luckily (or maybe unfortunately, depending on how you look at it), Rvan thinks about these sorts of things, and replied saying he was glad that I found it, but that he was going to delete that email so he didn't have that subject line presented to a few hundred of our users. The thing is, he didn't change the subject of the email when he replied, so when I got in the next morning and replied to his email telling him he was a spoilsport, I came really close to sending mail with the exact same subject. And that might have been a problem because Microsoft Outlook (ptui!) has a feature where it pops up a small window with the subject of newly-receive email.
I did happen to notice the subject before I sent it, and changed it to "RE: Great job Rvan!". Because, you know, sometimes I try to be nice.
Sadly, he had disabled the notification popup during his talks, so I wasn't able to use all of the rest of the subject lines I spent the rest of the afternoon coming up with.
Maybe next time...
