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.

It's always nice when my code doesn't crash

I was reading this article (link via Hacker News) about fuzz testing a DNS server and when I saw that the problematic packets that caused the program to crash could be downloaded, I figured I would give them a try against my own DNS parsing code.

My code did not crash, which is what I expected given that some of the tests I did included throwing random data. But I might have to install afl-fuzz and play around with it. I'd really love to throw afl-fuzz at the Protocol Stack From Hell™, and while it would be cathartic, in a way, that's like shooting already dead fish in a wine barrel with a double barrel shot-gun at point-blank range.

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.
