Q.01
Two decades ago only spies and systems administrators had to worry about passwords. But today you have to enter one even to do humdrum things like turning on your computer, downloading an album or buying a book online. No wonder many people use a single, simple password for everything.
Analysis of password databases, often stolen from websites
(something that happens with disturbing frequency), shows that the most common choices include “password”, “123456” and “abc123”.
But using these, or any word that appears in a dictionary, is insecure.
Even changing some letters to numbers ( “e” to “3”, “i” to “1” and so forth) does little to reduce the vulnerability of such passwords to an automated “dictionary attack”, because these substitutions are so common. The fundamental problem is that secure passwords tend to be hard to remember, and memorable passwords tend to be insecure.

Q.02
School
I was sent home the first day with a note: Danny needs a ruler.
My father nodded, nothing seemed so apt.
School is for rules, countries need rulers, graphs need graphing, the world is straight ahead.
It had metrics one side, inches the other.
You could see where it started and why it stopped, a foot along, how it ruled the flighty pen, which petered out sideways when you dreamt.
I could have learned a lot, understood latitude, or the border with Canada, so stern compared to the South and its unruly river with two names.
But that first day, meandering home, I dropped it.
