GTK+ (gtkrbtree.c): Spot the bug below: if (GTK_RBNODE_FLAG_SET (node, GTK_RBNODE_DESCENDANTS_INVALID)) { if ((! GTK_RBNODE_FLAG_SET (node, GTK_RBNODE_INVALID)) && (node->right != tree->nil && ! GTK_RBNODE_FLAG_SET (node->right, GTK_RBNODE_DESCENDANTS_INVALID)) && (node->left != tree->nil && ! GTK_RBNODE_FLAG_SET (node->left, GTK_RBNODE_DESCENDANTS_INVALID)) && (node->children && GTK_RBNODE_FLAG_SET (node->children->root, GTK_RBNODE_DESCENDANTS_INVALID))) GTK_RBNODE_UNSET_FLAG (node, GTK_RBNODE_DESCENDANTS_INVALID); }

gcc: You learn something new every day. Consider a function like:

static void foo (void) { foo (); }

This static function calls itself, and nothing else in the .c file calls it. As a result, the -Wunused-function argument won’t actually warn you that foo() is unused at compilation time. I found a 500 line recursive function in gtktreeview.c yesterday that was unused. Removing that function got that file under 10KLOC again. It’s still pretty unmanageable, but it’s a step in the right direction.

GNOME Foundation: Wow! I was voted in. I only hope we can do as good job as the last board did. This looks like it’s going to be a great board — though I do wish we could have squeezed Jeff and Glynn in there somehow.
GTK+ (GtkTreeView): Got incremental reflow sorta working yesterday. Tomorrow, I try to get column sizing right.

Website: Decided to play webmaster tonight and worked on my site a bit. Not quite ready yet to make it live. But I will put it up soon.
Music: Got “In The Beginning…” by Genesis recently. It’s all their early stuff. I hadn’t listened to it much since my roommate in college had it. It’s kind of fun.
GTK+ (GtkTreeView): Committed the last (knock on wood) API change for GTK+ 2.0 for GtkTreeView. I’m pretty happy with most of it. There are a few warts left (column sizing), but I think it’s definitely an improvement. For GTK+ 2.2, it’ll definitely be very cool.

Meta: Missed all of October. I went to another wedding in Chicago during that time. Zana and I got cell phones. I worked a lot on the GtkTreeView; it’s getting close to finished now. So much happened, so little was detailed. I suppose I should write it down so I can remember, if nothing else.
Design: The OXO Good Grips people continue to impress me. After a string of Mediocre products recently (I did not like their can opener) I was floored by their new Tea Kettle. Wow! I bet all Tea Kettles in the future work like that.
Location: I seem to be writing entries primarily in airports, nowadays. (-:

trip: Seems like the three days in England just flew by. I didn’t have much time to do too much work, let alone write on my ChangeLog. I saw my cousin get married.
hotel: One thing I would like to say is that the hotel we stayed at was excellent!!!

flight: Still over land, though this time it’s Ireland. Did I sleep? I don’t remember. Time for some quick tree hacking before we land.
laptop: updatedb is draining the battery.

flight: Still over land. Time for sleep. I got a lot of the small bits of the tree view looking good though.

food: Just had dinner. Limp salad with Heinz salad dressing in a ketchup packet. Lousy chicken and rice. Shrek on the TV. Mediocre Merlot. Whole wheat bread with cheese and butter. Crackers. Lemon cream pie, and a pecan chocolate shaped like a reeses peanut butter cup for dessert. Served with plastic cutlery. The merlot bottle seems more dangerous than the old metal knives they used to provide. Had Tea and a glass of ice water to wash it all down.
food (tea): Tea had heavy cream and Equal. I don’t know why I bothered with the equal.
flight path: Still over land. I had hoped we’d be over the atlantic by now.
nautilus: Seems to be having problems with my ChangeLog. Bad!
city lights: There’s very light cloud cover right now. As we hit variations in the cloud’s density the lights dim and brighten, much as if some one had a giant rheostat attached to them. I’d like to see the rheostat for the world.
