Precisely. Comments about code that the developer himself doesn't understand, usually because he employed some nasty hack and he's not sure exactly why it worked, are usually short and contain the word "magic" in them... /* I went on a vodka bender last night, and this was on my screen when I woke up. I don't know what it is, but it compiles, so let's ship the fucker. We'll call it Vista. */
On a few occasions I've found myself *needing* to code something while having an alarmingly high fever. Sometimes this is because something is actually due and sometimes it's because I just think I understand something.
The surprising thing about this was when I had a fever of 103.4 and was snowed in so I couldn't get to the hospital so I stayed awake all night. I programmed a 3d graphics engine... without properly understanding what I was doing... and it worked. It took me the next 2 weeks to figure out what I'd done, why it worked, and what it was doing before I could improve it. Took me almost that long to verify that I hadn't just cut and pasted from random websites while in my delirium. My browsing history was full of all sorts of random crap. I'm still not sure how it happened.
Suffice it to say that I now believe in the Ballmer Peak.
