• Programmatically measure size and way-order of L1 and L2 caches

  - by osgx

  How can I measure programmatically (not query the OS, but measure) the size and order of associativity of L1 and L2 caches (data caches)? Assumptions about system: It has L1 and L2 cache (may be L3 too, may be cache sharing), It may have a hardware prefetch unit (just like P4+), It has a stable clocksource (tickcounter or good HPET for gettimeofday). There are no assumptions about OS (it can be Linux, Windows, or something non-standard), and we can't use POSIX queries. Language is C. And compiler optimizations may be disabled.

• How to do case-insensitive order in Rails with postgresql

  - by brad

  I am in the process of switching my development environment from sqlite3 to postgresql 8.4 and have one last hurdle. In my original I had the following line in a helper method; result = Users.find(:all, :order => "name collate NOCASE") which provided a very nice case-insensitive search. I can't replicate this for postgresql. Should be easy - any ideas? Thanks.

  - by Andy Shea

  Is there an internal ID variable or timestamp I can use in a NSSortDescriptor to retrieve Core Data entities in the order they were inserted? I would rather not have to create such properties if there is a cleaner way, though will obviously do so if there are no other alternatives.

• JBoss Seam - order event listeners

  - by Walter White

  Hi all, I would like to order my event listeners. Is it possible to do this in JBoss Seam 2.x? I am thinking as a workaround, which is quite simple, I will just daisy chain my events: fire event A. do something on event A. a. fire event B do something on event B. Any comments with this design? Is this a good / bad practice? Thanks, Walter

• Conventions for order of parameters in a function

  - by Andy

  In writing functions my brain always spends a few milliseconds to check which order of parameters would be best for a given function. should I write: public Comment AddComment(long userID, string title, string text) Or probably: public Comment AddComment(string title, string text, long userID) Why not: public Comment AddComment(string title, long userID, string text) Do you follow any rules when ordering the parameters for your functions? Which parameter would you place first and which would follow?

  - by Kenji Crosland

  When users make credit card transactions on my web app, I'd like to include the transaction fee on the confirmation page before the user makes the order. The thing is, there are different transaction fees for different cards. Is there a way to determine a transaction fee from the card number? I'm using Rails and ActiveMerchant, but I figure this question was applicable to other languages as well.
