• A good Java library for network math

  - by perilandmishap

  I'm looking for a Java library that is geared towards network math and already tested. Nothing particularly fancy, just something to hold ips and subnets, and do things like print a subnet mask or calculate whether an IP is within a given subnet. Should I roll my own, or is there already a robust library for this?

• Are PHP5 objects passed by reference?

  - by morpheous

  I cant seem to get any consistent info on this. Different sources appear to say different things and trhe venerable php.net iteslf (appears) not to explicitly state this - although I must admit, I only had a quick look. In cases where I am passing around 'heavy' objects, I need to pass by reference, but I dont want to keep typing: function foo(TypeName& $obj) if I can get away with simply, function foo(TypeName $obj) So what does the standard say?

• SQL Server Query with "ELSE:"

  - by Mike D

  I have various VB6 projects I'm maintaining with some of the queries being passed to the server having "ELSE:" with the colon used in case statements. I'm wondering can someone tell me what the **ll the colon is used for? It causes errors in SQL2005 and greater, but SQL2000 works with no complaints. I'd like to just remove it from the code & re-compile, but I'm afraid it'll break 10 other things in the application.. Thanks in advance...

• Should the function or the caller be resonsible for input validation?

  - by haudenschilt

  I'm doing a security audit on a fairly large php application and was wondering where I should include my user-input validation. Should I validate the data, then send the clean data off to the back-end functions or should I rely on each function to do it's own validation? Or even both? Is there any standard or best-practice for this sort of thing? Currently the app does both inconsistently and I'll like to make things more consistent.

• What runs before main()?

  - by MikimotoH

  After testing on msvc8, I found: Parse GetCommandLine() to argc and argv Standard C Library initialization C++ Constructor of global variables These three things are called before entering main(). My questions are: Will this execution order be different when I porting my program to different compiler (gcc or armcc), or different platform? What stuff does Standard C Library initialization do? So far I know setlocale() is a must. Is it safe to call standard C functions inside C++ constructor of global variables?

• Creating multiple objects of a view defined in the xml

  - by user362953

  I have to dynamically add a list of views (the views use RelativeLayout). Can I do this by specifying the view definition in xml and instantiate multiple objects off it? This gives the usual benefits of separating the view part from the code (for e.g., making it easy for the UI guys to alter things) or Is going the ArrayAdapter the suggested/only route?

• How do you get the width of an element without a defined width?

  - by Moak

  How would you find out the width of a element that is wrapped by 20 odd other elements, but the only fixed width I know is the main wrapper's which is 800px. All child elements are generally blocks, floating or not, with different paddings and margins. I don't really need the answer to a specific case, I'm just wondering if there are tools or tricks to quickly calculate such things. Thanks

  - by viatropos

  I want to be able to map Google Docs' folder system to urls in my application and am just wondering how I can say "route, I want you to match an arbitrary set of nodes, and the last one is the file (or possibly a directory, I can check in the controller)". So I could do things like: www.mysite.com/documents/folder1/childfolderA/document www.mysite.com/documents/root-level-doc Can the routes.rb file do something like this?
