No, you do not have to do that. Here's an example of a custom comparison function to sort a list of strings by the second character:

a := []string{"afoo", "bbar"}
sort.Slice(a, func(i, j int) bool { return a[i][1] a[j][1] })

The inline function syntax is slightly verbose, but not terrible considering you need to write types.

Uh, it HAS been filling your log files with warnings about upgrading for months, if not years. It's pretty f'ing explicit:

I love how everyone here is telling you to just pencil and paper. For the past 7 years (through both college and high school), I have taken all of my math notes in Mathematica. Every symbol, even the most esoteric ones, is at most four or five keystrokes. For example, an integral like integral x=0 to inf (x^2)/xbar is quick to enter:

integral template -- ESC i n t t ESC
bound -- x = 0 TAB ESC inf ESC
value -- x C-6 2 RIGHT C-/ x C-5 UNDERSCORE

it's really quick to type, and you'll quickly learn the keystrokes from the character palette. I haven't taken a single note on paper in any of my math classes since about sophomore year of high school.

Much simpler:

openssl rand -base64 32 | head -c 10

Where "10" is the number of characters you want.
