• Easy way to convert a Doctrine_Collection of Model classes to an array of simple objects?

  - by Alex

  To clearly separate the Controller and View layers, I do not longer want to pass full objects to my views. Instead I want to pass only arrays and objects that contain the data but do not have any methods. Otherwise a view script would be able to delete Doctrine records or traverse in the object tree to data that was not intended for the view.

• [boost::filesystem] performance: is it better to read all files once, or use b::fs functions over an

  - by rubenvb

  I'm conflicted between a "read once, use memory+pointers to files" and a "read when necessary" approach. The latter is of course much easier (no additional classes needed to store the whole dir structure), but IMO it is slower? A little clarification: I'm writing a simple build system, that read a project file, checks if all files are present, and runs some compile steps. The file tree is static, so the first option doesn't need to be very dynamic and only needs to be built once every time the program is run. Thanks

• Memory leaks in libxml2.2

  - by KSH

  I am using libxml2 to parse xml content in my iPhone app. The xml content is downloaded from a server similar to the Apple's own TopSongs sample app. When I check for leaks using the Instruments tool, I see memory leaks being reported on xmlNewParserCtxt, xmlNewInputStream and xmlAllocParserInputBuffer. I have called xmlFreeParserCtxt(context) at applicable places (dealloc). Am I missing something else ? Is this a known issue to contend with when using libxml2 parsers ?

• How does browser search tool work on web page?

  - by GTM

  I am trying to figure out how the search tool in a web browser is being able to parse through the entire web page(assuming huge content on a page) and highlight the result as we type. Does it pre-cache the page while loading in a map or use regex to get a quick result on the fly?

• When is better to use a parser such as ANTLR vs. writing your own parsing code?

  - by ViralShah

  I need to parse a simple DSL which looks like this: funcA Type1 a (funcB Type1 b) ReturnType c As I have no experience with grammer parsing tools, I thought it would be quicker to write a basic parser myself (in Java). Would it be better, even for a simple DSL, for me to use something like ANTLR and construct a proper grammer definition?

• Static page routing in Sinatra (Ruby)

  You can serve static files with Sinatra by placing them in public/ (by default) -- I have an index.html in there at the moment, but how can I make the root point to that file without having to parse it as a template? To be clear, I can access /index.html successfully, and I'd like to route / to be the same static file, but without redirecting. Any idea how to do this?
