An interesting offshoot of this type of question is: how long does it take to hit every stop on a given transit system? BART has quite a few people making attempts; the official BART website even maintains a little article [1]! A couple have made videos of attempts and theory [2, 3], but the king of these things is tomo tawa linja, who I believe is the current record holder at 5:30:26 [4].

The NYC version has a wikipedia page[0]. The record is Kate Jones, in 22 hours, 14 minutes, 10 seconds.

High quality piracy, especially for music, can convey a lot of social status. Many of the “pirate clubs” online are gated behind presenting your own vault of gems: lots of lossless FLAC files and maybe some rare foreign cd rips.


Jon Gjengset has a good (~3h long) video going over a lot of this and more.

Just so you can see the bias to early numbers in the distribution:

    for i in $(seq 1000000); do
        echo $[RANDOM%10000]; 
    done | sort -n | uniq -c | sort -rn | gnuplot -e "set terminal dumb; set xtics 1000; plot '< cat' using 0:1 with boxes"


I think this gnuplot command makes the bias much more obvious (and even better with -persist and "set terminal x11"): gnuplot -e "set terminal dumb; set xtics 100; plot '<cat'"

Compare to the version that discards values over 3e4:

  for i in $(seq 1000000); do x=$((RANDOM)); while test $x -gt 30000;do x=$((RANDOM)); done; echo $((x%10000));      done |sort|uniq -c |sort -rn |gnuplot -e "set terminal dumb; set xtics 100; plot '<cat'"
Or the version that uses the 32-bit SRANDOM, which reduces the bias by a factor of 2**17:

  for i in $(seq 1000000); do         echo $((SRANDOM%10000));      done | sort -n | uniq -c | sort -rn |gnuplot -e "set terminal dumb; set xtics 100; plot '<cat'"


I always like Brian Kernighan's password "/.,/.," [1]. If you're going for a stupid password anyway might as well make is easy to type. "password" is not particularly nice to type; I wonder why "asdf" is not generally more popular.

asdf and qwerty were up there in the top 10 I think. This was just prior to the days of SQL injection and I'm 100% sure you could have erased our entire production DB with a really "strong" password.
