• iPhone Analytics

  - by ACBurk

  With the recent changes in the SDK agreement, I am kinda confused if I'm able to put any type of analytics into my app. I don't want to do anything nefarious, just want to see which functionality of my app is getting used the most. I was looking at Google Analytic's mobile sdk to track the different views, just like page views but I have a feeling it is not allowed anymore. Can someone clear up if Google Analytics are still allowed; if not, are any analytics allowed?

• PHP: Over-writing session variables

  - by Tom

  Hi, Question related to PHP memory-handling from someone not yet very experienced in PHP: If I set a PHP session variable of a particular name, and then set a session variable of the exact same name elsewhere (during the same session), is the original variable over-written, or does junk accumulate in the session? In other words, should I be destroying a previous session variable before creating a new one of the same name? Thank you.

• HTML 5 Canvas performance

  - by Vilius

  Hello there! I'm just started on playing around with the canvas HTML5-object. For the sake of performance tests, I have made a little ping pong game (http://bit.ly/arTPut). Apart from my quick'n'dirty programming skills, I believe, that there are also some performance boosts, I haven't used. Especially, the ball seams to be blue with a little red-touch, but by my decleration it should be yellow. Would be very nice, if someone could help me! Greetings, Vilius

• Scala println in a for loop

  - by random459

  The following Scala code does just what I expect it to - it prints each line of some_file.txt. import scala.io.Source val lines = Source.fromPath("some_file.txt").mkString for (line <- lines) print(line) If I use println instead of print, I expect to see some_file.txt printed out with double-spacing. Instead, the program prints a newline after every character of some_file.txt. Could someone explain this to me? I'm using Scala 2.8.0 Beta 1.

• True or False: Good design calls for every table to have a primary key, if nothing else, a running i

  - by Velika

  Consider a grocery store scenario (I'm making this up) where you have FACT records that represent a sale transaction, where the columns of the Fact table include SaleItemFact Table ------------------ CustomerID ProductID Price DistributorID DateOfSale Etc Etc Etc Even if there are duplicates in the table when you consider ALL the keys, I would contend that a surrogate running numeric key (i.e. identity column) should be made up, e.g., TransactionNumber of type Integer. I can see someone arguing that a Fact table might not have a unique key (though I'd invent one and waste the 4 bytes, but how about a dimension table?
