Callum's timetable program was released into the wild (Mosman High year 7) this week. There was a fraught few hours on day 1, when he realised that it didn't work with internet explorer (something nobody here had thought to check, but sadly which is used by the education department). Fortunately, though, with Ian (software mentor)'s assistance, the fix was only an hour or so of extra programming.
Callum didn't actually get to present it to the year 7s, as he was too busy at various other of his own subjects, but Evan did it for him, as part of the programming orientation, and got all the year 7s signed up.
Callum hasn't quite got up the nerve to see how many of the year 7s are actually using it yet.
