Online Development Tools

Not content with the tools found on the Internet, I've written a number of online utilities for my own modest needs...

• DNS Lookup – Performs a series of DNS, IP and Whois lookups. Searches are recursive, so all the relevant information is shown right away.
• Text Conversion – Online text encoder & decoder to convert between Base64, hexadecimal, quoted printable, JSON/Java strings, URL-encoding, XML-encoding, UTF-8 and more. Also calculates cryptographic hashes (e.g. MD5, SHA-1, SHA-256...) and includes a hex file viewer!

Other Resources

Here is a curated collection of other online resources to use when developing software:

• Web Development – These references for HTML, CSS & JavaScript are great. And check Can I Use for cross-browser compatibility.
• Color – Still no color tools to recommend. But try this, that or the other.
• Date & Time – Epoch Converter translates between Unix timestamps and readable dates.
• Regular Expressions – RegEx Pal and Regular Expressions 101 both provide help and interactive testing for regular expressions.
