A great Wikipedia page about solder alloys, including info about melting points.
There is also this Alloy Temperature Chart with similar info.
Today I learned about SMD soldering by hot air.
Today while reading Make: Getting Started with Soldering I learned about NASA WORKMANSHIP STANDARDS and the Lineman’s splice.
Today I watched Soldering Crash Course: Basic Techniques, Tips and Advice.
