How to test if a gawk string contain a number?
- by Tim Menzies
In gawk I know two ways to test if a string contains a number. Which is best? Method one: using regular expressions: function method1(x) { return x ~ /^[+-]?([0-9]+[.]?[0-9]*|[.][0-9]+)([eE][+-]?[0-9]+)?$/ } Method two: the coercion trick (simpler): function method2(x) { return (x != "") && (x+0 == x) } Is there any reason to favor the more complex method1 over the simpler method2?Read the article

How to balance number of ratings versus the ratings themselves?
- by zneak
Hello guys, For a school project, we'll have to implement a ranking system. However, we figured that a dumb rank average would suck: something that one user ranked 5 stars would have a better average that something 188 users ranked 4 stars, and that's just stupid. So I'm wondering if any of you have an example algorithm of "smart" ranking. It only needs to take in account the rankings given and the number of rankings. Thanks!Read the article
