  • Version 2.10 - Deadline: Saturday, April 21, 2007
    • Be a human CF compiler. This is a brain teaser so resist the urge to fire up a scribble page to test. Can you spot the five errors?
      <cffunction name="funkyMethod" access="public"        returntype="struct" output="false">        <cfargument name="someStruct" type="struct" required="true"/>            <cfset var coolThings = "" />            <cfloop collection="arguments.someStruct" index="i">
      <cfif arguments.someStruct[i] EQ "cool" />          <cfset ListAppend(coolThings, i) />       </cfif>    </cfloop>            <cfreturn coolThings /></cffunction>
    • Winner: Matt Osbun!
    • Answer:
      1. the stucture to be looped over in the collection attribute needs #'s around it
      2. looping over a struct with cfloop uses item NOT index
      3. the var i for the loop has NOT been var'ed
      4. the returntype for the method has been defined as struct when you are really returning a string
      5. ListAppend doesn't modify the list, it returns the original list of the value you wanted append. You must assign it to a variable.
      6. Bonus (Accidental error) - The <cfif> tag was closed "/"
  • Version 2.11 - Deadline: Saturday, April 28, 2007
    • You're looping over a query with cfloop and you want to highlight ever over row of data so you need to know which row number is getting outputted (using the MOD trick). What variable tells you this when using cfloop with a query? Hint, Livedocs is missing this!
  • Version 2.13 - Deadline: Saturday, May 5, 2007
    • Another programming exercise! Matt ran into this at work and thought it would be interesting to see how other people would solve this problem.

      Assume you have an array with n number of elements, and you want to retrieve a random number of elements from this array. The random number you want to retrieve is less than n, but greater than 1, and you cannot retrieve the same element twice. So for example, let's say your array has 10 elements in it and you want to retrieve 5 random elements, but none of these 5 can duplicate one another. How would you do that?

  • What Matt's been up to:
    • MachBlog final coming out either this weekend or very early next week. Yes, there's more to do, but we'll get 1.0 out and start adding stuff immediately thereafter. Next on the list are my CFUG app and BoardFusion
    • Lots and lots of work-related stuff
    • Just got back from the kite festival here in DC--very cool to see hundreds of kites flying around the monuments. And yes, I forgot my camera.
    3. Won't have a show next week since it's Easter weekend, however we'll do a short 5 minute show announcing the winner of the 2nd (and last) pass to cf.Objective()
  • What Peter's been up to:
    • Celebrating my birthday - I'm a fools baby
    • Talked with Kurt about Mach-II 1.5 (at my party at that) and the things the last things that need to be finished before cf.Objective()
