Notes:

I'm a second-year law student at Columbia Law School, which is supposed to be an all-consuming status, but I still find time to hack--- it's a great distraction from Real Work. After four years of CS in college, it's somewhat liberating to be back to coding as a hobby: what I want, when I want. Recently, most of my programming time has gone into writing and maintaining the moderation software for the Usenet newsgroup soc.culture.jewish.moderated, of which I am one of the five moderators. It's a bunch of Perl scripts and a MySQL database, but while relatively simple in theory, always seems to have more features needed to make our lives as moderators livable. :) Beyond that, I am theoretically one of the maintainers of gnome-pim, but I haven't even done much bug-fixing recently.I'd like to work on Evolution when I get some free time, specifically the calendar component. I also have several other projects on a back burner, including a Hebrew calendar program I've been working on for, oh, four years or so without significant progress. :)

I should have posted this yesterday, but I didn't... So imagine it was dated 02 Apr 2000.

Days with less than 24 hours really suck. I spent the better part of the afternoon fighting a bug in gnomecal which caused a crash (SIGFPE) on startup --- fussy computer, didn't like dividing by zero. :) It seems there is a special case which prevents the divide by zero 364 days of the year, but on the day when DST starts (and the assumption # of hours/day == 24 is not applicable), it doesn't trigger leading to the crash.

The tricky part was figuring out a fix: I am pretty sure the entire daylight savings time logic which was patched in a year or so ago is broken, but I need to do some more checking/testing to prove it...

On the other hand, this did show that gnomecal has users: I have now received in excess of fifteen different reports of this bug, which means that at least that many people tried to start gnomecal yesterday. :)

The iCalendar parser can load at least one trivial test file. It still doesn't handle recurrences or alarms, though, and gnomecal crashes on exit (since it can't save the file, I think).

More work for tomorrow...

The iCalendar parser for gnomecal finally compiles, although I haven't yet written enough testing code to see if it actually does anything useful. We're going to need to rewrite a large part of the recurrence engine to get this to work, so it's not going to work in the larger sense of having a functional calendar for a while. (Unless HelixCode decides to throw its weight at the rewrite, I guess.)

I also cleaned up the first patch for extending gnomecal's internal structures for iCalendar and sent it to calendar-list for review.

And since tomorrow's a University Holiday here, maybe I'll get some more hacking done. Although I do need to send out resumes and get stuff together for my girlfriend's birthday...

I did some more work on the libical parser for gnomecal, but exams this week are a higher priority, so I don't expect to get much more hacking done for a few days...

I found the wmSun WindowMaker dock applet today, which has GPL'ed code for sunrise/sunset calculations. It will take some modifications, but it should give a boost to luach (my Hebrew calendar program), so that I might actually get it finished this century. Oops- not much time left. :)

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.

Keep up with the latest Advogato features by reading the Advogato status blog.

If you're a C programmer with some spare time, take a look at the mod_virgule project page and help us with one of the tasks on the ToDo list!
