I have a Rails model that should only allow saving/updating of a model once per day per user. I have a callback to do the Find by user and date then add to errors but this is ugly and feels un-rails-like. I have the typical created_at / updated_at columns (and the time portion is significant/I need to keep it). So I figure I could eithe...
I feel like this must have been asked, but I'm unable to find it through my searches. Here's a complete example of the issue that's confusing me: <html><head> <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script> <script type="text/javascript"> (function($){ $.fn.test...
This may have been asked before but I have no idea how to word it to search for it. I have a composite widget that has methods to update some of the widgets that make up the composite widget.

I have a question relating to Perl and scoping. I have a common file with lots of various variables. I require the common file in my main script, but I cannot access the variables; they seem to be outside of its scope. I assumed that an our declaration would overcome that problem, but it doesn't seem to work. Script 1: common.pl #!/usr...

When I compile the following code with g++, the object of class A seems not to be destructed when the object of class C is constructed, and the B.ref_a reference is not broken when accessed by the constructor of object of class C: #include <iostream> struct A { A(int aa) { a = aa; } ~A() { std::cout << "A...
OK, so I'm trying to use S4 classes to build a very complex object, with slots including a half-dozen matrices, a few lists, and probably a kitchen sink or two in there. The object is initialized by referring to and unpacking a configuration object which I've already defined. It's easy enough to define the class with setClass(), but I'm ...
