I always assumed that pretty much everyone knew that the phrase "I could care less" doesn't make literal sense. I assumed it was simply an unfortunate shortened form of "I couldn't care less". I think it's popular because it has better cadence. It might be helped along by the likely element of sarcasm in it. … Continue reading I could care less about your word crimes
This post is a survey of some run-length encoding (RLE) data compression formats, most of which are used for bitmapped graphics. One such format is PackBits. It's sort of the granddaddy of them, or the canonical example of such a format. Sometimes, formats similar to it are said to be "PackBits-like", though the term doesn't … Continue reading Survey of PackBits-like RLE compression schemes
Public opinion seems to be turning against Daylight Saving Time (DST), despite the fact that most of our clocks now change automatically, and despite the fact that most people don't even seem to have a clear understanding of what DST does, and what its purpose is. I'm not necessarily the biggest proponent of DST, but … Continue reading Daylight Saving Time

Many thousands of free and shareware programs were written for Windows 3.x, and a lot of them include some documentation in Write's WRI file format. Objectively, most of them should … Continue reading Analyzing some Windows Write files
Remember the Great TLS Certificate Serial Number Brouhaha of March, 2019? Millions of website certificates have been mis-issued! Everything is insecure! The sky is falling! Revoke and replace, ASAP!

Does "0.99999999…", with the 9s continuing indefinitely, equal 1? Well, of course it does. This is not a new question. The internet was invented on a Tuesday, and by Wednesday afternoon half of its denizens were trying to explain to the other half why 0.999… does, in fact, exactly equal 1. The explanation, we're told, … Continue reading Does 0.999… equal 1?
Are humans descended from monkeys? It's an interesting question. Too many well-meaning scientifically-minded individuals are quick to reply with a defensive "No! We just have a common ancestor!" But that's not a very good answer. It ignores the fact that the question is ambiguous, and that the definition of "monkey" is ambiguous. Sometimes the answer … Continue reading Are humans descended from monkeys?
