Bitrate decides the file size, resolution does not Two 4K files can differ tenfold. The pixels are a claim about detail; the bitrate is what was actually stored. Alphabets built to be heard, not read Alfa and Juliett are spelled wrongly on purpose, so that speakers of other languages say them correctly. A dead pixel and a stuck pixel are not the same fault One is permanently off and unrecoverable. The other is permanently on and sometimes fixes itself, which is why the distinction is worth five minutes. Dew point is the honest humidity number Relative humidity changes when the temperature does, without any water moving. Dew point does not, which is why it predicts how the air feels. How old are you in hours A birthday is one measurement of age among many, and the smaller units produce milestones worth noticing more often. Why 110 pixels per inch is the comfortable number 24-inch 1080p and 27-inch 1440p feel the same because they are. Density, not resolution, is what your eye reads. A month is not a fixed length Add one month to 31 January and there is no correct answer. Every date library picks one, and they do not all pick the same. Why a random ID makes a poor database key A v4 UUID is 122 random bits inserted in no order at all, which is exactly what an index does not want. A gradient to transparent fades through grey Because transparent means transparent black. Fade to the same colour at zero alpha instead, and the muddy middle disappears. camelCase, snake_case, and where each belongs Kebab-case is illegal as an identifier in most languages, because the hyphen is already the minus sign. Lossy, lossless, and what a compressor can actually remove A quality slider does nothing to a PNG. That is not a bug; it is the definition of the format. Blocking a page in robots.txt does not hide it Disallow stops crawling, not indexing. A blocked page can still appear in results, and blocking it prevents the tag that would remove it.
