Online Development Tools

Here is my curated collection of online resources that I use when developing software:

	Text Conversion – An online text encoder & decoder to convert between Base64, hexadecimal, quoted printable, JSON/Java strings, URL-encoding, XML-encoding, UTF-8 and more.
	Cryptographic Hashes – A tool to calculate various cryptographic hashes from a text string, such as CRC-32, MD5, SHA-1 and SHA-256.
	Binary Files – An online tool to view binary files, extract some meta-information and generate data URI:s for small images.
	Search Placement Tracking – An online tool to quickly check placement in search results. Also known as SERP tracking.
	Web References – Google works fine, but these are great: HTML, CSS, JavaScript, Quirksmode & W3C Validator
	Color – Still haven't found a color tool that can handle everything. But Color Scheme and Color Codes both work quite well.
	Date & Time – Epoch Converter translates between Unix timestamps and readable dates.
	Regular Expressions – RegExPal allows interactive testing of regular expressions.
