The Boston Diaries

The ongoing saga of a programmer who doesn't live in Boston, nor does he even like Boston, but yet named his weblog/journal “The Boston Diaries.”

Go figure.

A quick note about the GNU Debugger

Just a quick note here—you can still debug a program using gdb if the debug information exists in the executable, even if gdb doesn't have access to the source files. It will still print out filenames and line numbers, and you can still examine the contents of variables. I just spent an hour with TS debugging an issue with “Project: Lumbergh” on our lab machines, running gdb in one terminal, and an editor in a second terminal following the files and line numbers given by gdb.

Not quite the optimum experience, but at least it was doable.

I'm also not sure what it says about “Project: Lumbergh” that the issue turned out to be a configuration issue—the configuration was legal at one time, but not with a newer version of the code. I think the codebase is slowly turning into a big ball of mud.

You have my permission to link freely to any entry here. Go ahead, I won't bite. I promise.

The dates are the permanent links to that day's entries (or entry, if there is only one entry). The titles are the permanent links to that entry only. The format for the links are simple: Start with the base link for this site:, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

You can also specify the entire month by leaving off the day portion. You can even select an arbitrary portion of time.

You may also note subtle shading of the links and that's intentional: the “closer” the link is (relative to the page) the “brighter” it appears. It's an experiment in using color shading to denote the distance a link is from here. If you don't notice it, don't worry; it's not all that important.
