PHP: Dealing With MySQL Connection Variable
What is the best way to deal with the $db_conn variable once I create a mysqli object? I've been using $GLOBALS['_sql'] = new mysqli(...); But this seems dirty. The alternative that I've seen is to be constantly passing the connection var to every function that calls it, but that's a huge pain. ...
C# Common Data Parameters
Greetings, I'm a beginner to OO and programming and I have the following situation: I have a set of const values and enums that several of the classes I implement share. These classes are independent i.e. other than sharing these values, they do not interact with each other, so inheriting them won't work. I was wondering; If I create...

are runtime linking library globals shared among plugins loaded with dlopen?
I've a C++ program that links at runtime with, lets say, mylib.so. then, the same program uses dlopen()/dlsym() to load a function from myplugin.so, dynamic library that in turn has dependencies to mylib.so. My question is: will the program AND the function in the plugin access the same globals defined in mydlib.so in the same memory ar...
Objective C defining UIColor constants
Hi, I have a iPhone application with a few custom-defined colors for my theme. Since these colors will be fixed for my UI, I would like to define the colors in a class to be included (Constants.h and Constants.m). How do I do that?

Globals are bad! But should I use them in this context?
Would setting the $link to my database be one thing that I should use a GLOBAL scope for? In my setting of (lots of functions)...it seems as though having only one variable that is in the global scope would be wise. I am currently using the functions to transfer it back and forth so that way I do not have it in the global scope. But it...

The import statement that celery is using is this: __import__(module, [], [], ['']) Oddly enough, when this syntax is used, the module gets imported twice, once as jiva_tasks and another time as jiva_tasks. (w...
Best Practice for globals in clojure, (refs vs alter-var-root)?
I've found myself using the following idiom lately in clojure code. (def *some-global-var* (ref {})) (defn get-global-var [] @*global-var*) (defn update-global-var [val] (dosync (ref-set *global-var* val))) Most of the time this isn't even multi-threaded code that might need the transactional semantics that refs give you. It jus...
