  - by Anonymous

  I'm working with a time sensitive desktop application that uses p/invoke extensively, and I want to make sure that the code is not wasting a lot of time on CAS stackwalks. I have used the SuppressUnmanagedCodeSecurity attribute where I think it is necessary, but I might have missed a few places. Does anyone know if there is a way to monitor the number of CAS stackwalks that are occurring, and better yet pinpoint the source of the security demands?

• 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?

• 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!
