General Development "I was reading about vim the other day and found out why it used hjkl keys as arrow keys. When Bill Joy created the vi text editor he used the ADM-3A terminal, which had the arrows on hjkl keys, so naturally he reused the same keys." As interesting as that is, John Graham-Cumming goes even further back in history. "The reason that keyboard had those arrows keys on it was because those keys correspond to CTRL-H, J, K, L and the CTRL key back then worked by killing bit 6 (and bit 5) of the characters being typed." Truly fascinating stuff, even though it's from way before my time (I'm from 1984).

...but for me this is much more exciting than iPad's release!

I was equally excited to discover that ~ is the HOME key on the ADM-3A. Yay! More usual trivia to annoy people with!

I could have been interested in the resulting discussions about high-resolution screens and current tablets being intentionally crippled machines, but then the SNR just became too low.
