Selected quotes:
[...] you can ask almost any programmer today about the code
they are working on. “It’s a big hairy mess,” they will tell
you. “I’d like nothing better than to throw it out and start
over.”
Why is it a mess?
“Well,” they say, “look at this function. It is two pages long!
None of this stuff belongs in there! I don’t know what half of
these API calls are for.”
[...]
Yes, I know, it’s just a simple function to display a window,
but it has grown little hairs and stuff on it and nobody knows
why. Well, I’ll tell you why: those are bug fixes. One of them
fixes that bug that Nancy had when she tried to install the
thing on a computer that didn’t have Internet Explorer. Another
one fixes that bug that occurs in low memory conditions. Another
one fixes that bug that occurred when the file is on a floppy
disk and the user yanks out the disk in the middle. That
LoadLibrary call is ugly but it makes the code work on old
versions of Windows 95.
Each of these bugs took weeks of real-world usage before they
were found. The programmer might have spent a couple of days
reproducing the bug in the lab and fixing it. If it’s like a lot
of bugs, the fix might be one line of code, or it might even be
a couple of characters, but a lot of work and time went into
those two characters.
When you throw away code and start from scratch, you are
throwing away all that knowledge. All those collected bug fixes.
Years of programming work.
