This is my first time working with binary data, binary specifications, etc., and I've started to mess around with the dBASE file format [0] after reading about it in NodeJS in Practice [1]. I know about the usual ones (e.g., PNG, JPEG, etc) at least by name and I'm now wondering about what's out there, especially less well-known formats or niche ones.

I'm reading Petzold's Code [1], and it dawned on me that I didn't understand logic gates intuitively until now. I took a Computer Architecture course back in college, and I understood what logic gates meant in boolean algebra but not empirically. Petzold clarified this for me by going from the empirical to the theoretical using a lightbulb, a battery, wires, and relays (which he introduces when he talks about the telegraph as a way to amplify a signal).

Another concept is the relationship between current, voltage, and resistance. For example, I always failed to understand why longer wires mean more resistance while thicker wires mean less resistance.
