# Simple bijective function
#   Basically encodes any integer into a base(n) string,
#     where n is ALPHABET.length.
#   Based on pseudocode from http://stackoverflow.com/questions/742013/how-to-code-a-url-shortener/742047#742047

ALPHABET =
  "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789".split(//)
  # make your own alphabet using:
  # (('a'..'z').to_a + ('A'..'Z').to_a + (0..9).to_a).shuffle.join

Setting up and installing rbenv, ruby-build, rubies, rbenv-gemset, and bundler

This guide enables you to install (ruby-build) and use (rbenv) multiple versions of ruby, isolate project gems (gemsets and/or bundler), and automatically use appropriate combinations of rubies and gems.

TL;DR Demo

Dear Rubyists,

I just lost a contract because of my code in a Rails project.

The specific code in question is related to a "posting a comment" feature. Here are the details:

In this project, "posting a comment" does not simply entail inserting a row into the database. It involves a procedure to yes, insert a row, but also detect its language, check for spam, send emails, and "share" it to Twitter and Facebook. I believe this algorithm should be encapsulated. I do not believe it belongs in a controller or a model. I do not believe Active Record callbacks should be used.

The "senior developer", whom is the stake holder's right hand man, said this:

tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

# For context, this was inspired by the RubyRogues podcast #79 where they talked about
# documentation in Ruby, and specifically grumbled quite a bit about the failings of RDoc.

#
# As someone who's spent a lot of time using an IDE for programming C# and Java, I think 
# Ruby could do a lot better at putting documentation at our fingertips as we program.
#
# Maybe making the documentation part of the structure of the code would facilitate this?

Some scripts/configurations that greatly improve tmux/vim workflows. The shell scripts target zsh but should be adaptable without much effort for other unix shells.

Features:

• Transparently move between tmux panes and vim windows
• Using the shell, open files in one vim instance per project or directory
• Fully integrated copy/paste between tmux, vim and x11 using simple keybinds(need to install the xclip program)
• Easily send text to any tmux pane without breaking your edit workflow(needs slimux

'vim-tmux-move.zsh', '.vimrc' and '.tmux.conf' cooperate so you can move transparently between tmux panes and vim windows using ALT + (arrow keys or jkhl). It was based on this gist
