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.

Stupid GCC Compiler Tricks

Years ago I implemented my own language, and in the process of writing that, I seriously abused the C pre-processor to give me a form of template-based programming (templates are now part of the C++ standard), and while using the template wasn't that bad:

void _MKFUNCTION(T_PREFIX,_matrix)(void)
  char *s;
  s = get_token(fpin,whitespace);

But you had to be very careful how you included the templates stuff, or it would most definitely blow up in your face.

But this—implementing a “read-evaluate-print-loop” in C, for C—is sheer genius. Or sheer insanity. I'm not sure which.

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.

It is assumed that every brand name, slogan, corporate name, symbol, design element, et cetera mentioned in these pages is a protected and/or trademarked entity, the sole property of its owner(s), and acknowledgement of this status is implied.
