1 Comment. Add comments to your code in plain English (or your native language if the other programmers who will be reading it also speak the same language) that describe both what the code is doing and why you decided to do it one way and not another way that somebody reading the code might think of on their own.
2 Don't assume output formats. Sometimes data will get output to the screen, other times to a printer, and other times it will get logged to a database.
3 Use globals sparingly. Global variables suck.
4 Consolidate literals. Literals belong in a centralized spot (e.g. a separate module or a database), not sprinkled liberally throughout your code. That means you should refer to them symbolically (i.e. by name, not literal value).
5
Be consistent with formatting. There's nothing worse than code that is difficult to read because it is poorly formatted.
