I didn't get content until today anyway so it all works out. I stayed a little late tonight getting the first block of it into the layout, but when I merged my files with another developer's our versions were in conflict. After a cursory attempt to rectify the conflict I decided to go home. I had already attained Last Developer Standing status for the day and I needed Fred around to do the merge anyway. Tomorrow, then. Wish me luck, space cadets.
Mattie had a look at my web app I've been working on in his virtual machine and it ran just fine. Now, on the whole, this is very good news, because it means I don't have to be as concerned about IE6 users. At the same time, though, it also means that I've basically wasted half the time I've spent optimizing and that I've committed a cardinal sin of programming: optimizing prematurely. Even though I believe that it's understandable I didn't run around the office trying it out on everybody's virtual machine, I still feel pretty foolish having not asked a single coworker to have a look when I discovered something anomalous. Live and learn, I guess.
