58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

ANSI Escape Sequences

Standard escape codes are prefixed with Escape:

Ctrl-Key: ^[
Octal: \033
Unicode: \u001b
Hexadecimal: \x1B
Decimal: 27

How to calculate accurate entropy of the session ID

1. What is an entropy?

Claude Shannon says:

The entropy is a statistical parameter which measures in a certain sense, how much information is produced on the average for each letter of a text in the language. If the language is translated into binary digits (0 or 1) in the most efficient way, the entropy H is the average number of binary digits required per letter of the original language.

-- NIST Special Publication 800-63-1 - Appendix A: Estimating Password Entropy and Strength

2. Why you need to know the accurate entropy?

Install Screen

$ sudo apt install screen

Enter a new Screen Session

$ screen

Detach from current screen session

Racket & scheme are orders of magnitude faster than clojure.

I like lisp but I hate this clojure movement. Especially when 60% of it is written in Java.

Are there major java libraries for which there is no scheme implementations?

Why did people pick up clojure rather than racket. Hype?
