58 bytes of css to look great nearly everywhere

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;
}

WebAssessment: How to calculate accurate entropy of the session ID

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?

Racket-Lisp-Scheme-Clojure Rant and Answers.

Two gentlemen and their rant on languages.

Rant

  • 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?

Vim without NERD tree or CtrlP

Vim without NERD tree or CtrlP

I used to use NERD tree for quite a while, then switched to CtrlP for something a little more lightweight. My setup now includes zero file browser or tree view, and instead uses native Vim fuzzy search and auto-directory switching.

Fuzzy Search

There is a super sweet feature in Vim whereby you can fuzzy find your files using **/*, e.g.:

:vs **/*<partial file name><Tab>
