Regular Expression Cheatsheet

Anchors

	enabled. Many regex implementations have multi-line mode enabled by
	default.

$ Matches at the end of string or end of line if multi-line mode is enabled.

Thoughts about Rails Presenters

This is a collection of links, examples and rants about Presenters/Decorators in Rails.

The "Decorator" pattern slowly started gaining popularity in Rails several years ago. It is not part of core Rails, and there's many different interpretations about how it should work in practice.

Jay Fields wrote about it in 2007 (before he switched back to Java and then Clojure): http://blog.jayfields.com/2007/03/rails-presenter-pattern.html

	# Name: Bash CheatSheet for Mac OSX

	# A little overlook of the Bash basics

	// Insert thumbnails of your Drive image files into a Google Sheet.
	// Images are inserted directly into the cells of the sheet, not as those useless overlays that float around.
	//
	// This is set up to scan the first two columns of the active sheet. Column A will contain an =IMAGE(url) formula, which is calculated by finding the image thumbnail for the file referred to by column B.
	// While this is simply the code I used for my own particular purpose, you can easily adapt it for your own needs. Please note that while an onEdit() version of this script would be cool, it will not work.
	// Formulas cannot access most other Google Apps services, though you could probably use a data store if you felt ambitious enough.
	// Note: the Drive Advanced API must be activated for this script to work.
	//
	// The script looks for files based on the pattern below:

	admin account info" filetype:log
	!Host=. intext:enc_UserPassword=* ext:pcf
	"# -FrontPage-" ext:pwd inurl:(service \| authors \| administrators \| users) "# -FrontPage-" inurl:service.pwd
	"AutoCreate=TRUE password=*"
	"http://:@www” domainname
	"index of/" "ws_ftp.ini" "parent directory"
	"liveice configuration file" ext:cfg -site:sourceforge.net
	"parent directory" +proftpdpasswd
	Duclassified" -site:duware.com "DUware All Rights reserved"
	duclassmate" -site:duware.com

	# This is just a cheat sheet:

	# On production
	sudo -u postgres pg_dump database \| gzip -9 > database.sql.gz

	# On local
	scp -C production:~/database.sql.gz
	dropdb database && createdb database
	gunzip < database.sql.gz \| psql database
