RegEx
I have been thinking about learning RegEx. It seems like you can cut down coding with the use of RedEx, i.e. extracting data from a string, replace data from string.
With inbuilt support in PHP (my primary coding language, still, for now) it seems to be only step to take. But as I said before there are only twenty-four hours in a day.
I think i got the hang of it, it wasn't that hard to learn once you got going. The best source i found was wikipedia article on RegExp.
