• JS and Rails site wide announcements

  - by pcasa

  Tried doing http://davidwparker.com/2008/09/17/site-wide-announcements-in-rails-using-jquery-jgrowl/ Am really bad with JS. Think I am messing up on the last part where it says "This code goes in your application.js file (somewhere in $(function){ //here })" Am I not suppose to do a link_to_function and create a function with this code that references that link? Really lost on this one.

  I know there is another question related to copying objects in JavaScript here, but the code they provide does not work with greasemonkey. From what I was able to trace, the code for the accepted answer dies/ stops at the line : var temp = new obj.constructor(); Is there any way to see what went wrong ? It's not really necessary I use the same function for the object copying, but I would like something that works. Do you know some function?

Looking forward to your opinions.

  It appears that the NetBeans UML plugin has been discontinued, as per a discussion on the NetBeans forums. This was a great, free tool with nice model-code and code-model generation.

• Adding metadata attributes to MySQL table

  - by Jack

  I would like to add custom attributes to a MySQL table which I can read via php. These attributes are not to interfere with the table itself - they are primarily accessed by php code during code generation time and these attributes HAVE to reside in the DB itself. Something similar in concept to .NET reflection. Does MySQL support anything like this? Thanks.

• generic programming in C with void pointer.

  - by Nyan

  Hi everyone, even though it is possible to write generic code in C using void pointer(generic pointer), I find that it is quite difficult to debug the code since void pointer can take any pointer type without warning from compiler. (e.g function foo() take void pointer which is supposed to be pointer to struct, but compiler won't complain if char array is passed.) What kind of approach/strategy do you all use when using void pointer in C?

  - by NickLarsen

  I have been looking through some code on an open source project recently and found many occurrences of this kind of code: class SomeClass { private int SomeNumber = 42; public ReturnValue UseSomeNumber(...) { int someNumberCopy = this.SomeNumber; if (someNumberCopy > ...) { // ... do some work with someNumberCopy } else { // ... do something else with someNumberCopy } } } Is there any real benefit to making a copy of the instance variable?

• How do I get user input to refer to a variable in Python?

  - by somefreakingguy

  I would like to get user input to refer to some list in my code. I think it's called namespace? So, what would I have to do to this code for me to print whatever the user inputs, supposing they input 'list1' or 'list2'? list1 = ['cat', 'dog', 'juice'] list2 = ['skunk', 'bats', 'pogo stick'] x = raw_input('which list would you like me to print?') I plan to have many such lists, so a series of if...then statements seems unruly.
