Blerf is a word coined by a former boss - and still friend - as a placeholder for a more precise word or definition. "Blerf" generally gives way to the improved word or definition as work progresses.
So, it is a placeholder for just about anything. Like a Conrail locomotive.
This blog is a spot for just about anything I care to write that I'd like to keep and look at later. If anyone else likes looking at or reading - that's fine. I could put this stuff elsewhere, but I'd forget where I put it, or even that I did it. So, uh. blerf.
