• BitSet to and from integer/long

  - by ataylor

  If I have an integer that I'd like to perform bit manipulation on, how can I load it into a java.util.BitSet? How can I convert it back to an int or long? I'm not so concerned about the size of the BitSet -- it will always be 32 or 64 bits long. I'd just like to use the set(), clear(), nextSetBit(), and nextClearBit() methods rather than bitwise operators, but I can't find an easy way to initialize a bit set with a numeric type.

• Assigning property to JS object using another objects property value as the property name

  - by hamstar

  Hey guys, I want to use the value of an objects property to name the property of another object. Easy to do in PHP: $object1->property = 'name'; $object2->{$object1->property} = "value"; echo $object2->name; //outputs "value" But in Javascript I can't figure out how to do this. The curly braces are used a different way. Anyone know the php equivalent in javascript? Thanks :)

• Python: Create a duplicate of an array

  - by Dan

  I have an double array alist[1][1]=-1 alist2=[] for x in xrange(10): alist2.append(alist[x]) alist2[1][1]=15 print alist[1][1] and I get 15. Clearly I'm passing a pointer rather than an actual variable... Is there an easy way to make a seperate double array (no shared pointers) without having to do a double for loop? Thanks, Dan

• sort associative array in awk - help?

  - by Richard

  Hi all, I have an associative array in awk that gets populated like this... chr_count[$3]++ When I try to print my chr_counts I use this: for (i in chr_count) { print i,":",chr_count[i]; } But not surprisingly, the order of i is not sorted in any way. Is there an easy way to iterate over the sorted "keys" of chr_count?

• Converting Straight Quotes to Curly Quotes

  - by BlueVoid

  I have an application which uses a javascript based rules engine. I need a way to convert regular straight quotes into curl (or smart) quotes. It'd be easy to just do a string.replace for ["], only this will only insert one case of the curly quote. The best way I could think of was replace the first occurrence of a quote with a left curly quote and every other one following with a left, and the rest right curly. Is there a way to accomplish this using javascript?

• Does mixing Quartz and OpenGL-ES cause big performance degrade??

  - by Eonil

  I have a plan to make a game using OpenGL for 3D world view, and CALayer(or UIView) for HUD UI. It's easy to imagine performance degrade from mixing them, but the document which mention this impact disappeared: http://developer.apple.com/iphone/library/technotes/tn2008/tn2230.html I cannot find the document on current version of SDK reference. And I got this document: http://gamesfromwithin.com/gdc-2010-the-best-of-both-worlds-using-uikit-with-opengl If you experienced about this, please let me know about performance impact on current SDK.

• Access control for cross site requests in Internet Explorer

  - by Aleksandar

  I am trying to make an AJAX call from several domains to a single one which will handle the request. Enabling Cross domain in Firefox and Chrome was easy by setting the header on the handling server: header("Access-Control-Allow-Origin: *"); But this doesn't help enabling it in Internet Explorer.

• How to convert RGB to BGR?

  - by Adam

  This is probably easy, but I'm trying to convert from a source which provides colors in RGB strings to an output in BGR strings in Java. I've been busting my brain and time on shifting and Long.decode and Long.toHexString. Feel free to also throw alpha values in there (RGBA - ABGR), though I think I can extend the principles.

  Is there an easy way to see the actual SQL generated by a rails migration? I have a situation where a migration to change a column type worked on my local development machine by partially failed on the production server. My postgreSQL versions are different between local and production (7 on production, 8 on local) so I'm hoping by looking at the SQL generated on the successful migration locally I can work out a SQL statement to run on production to fix things....
