The application I'm writing is almost complete and I'd like people who speak different languages to use it.
I'm not sure where to start, what's the difference between globalisation and culture in regards to programming?

[umbraco][1] gets my vote as a good CMS that comes close to Joomla in maturity and out of the box functionality. I'm not that fond of DNN, but it's been at least a year since I ran it thru its paces.

You should be aware of the fact that your original attempt

My experience is that continuous testing within the IDE can become unwieldy and distracting, so I prefer to use something like [CruiseControl](http://cruisecontrol.sourceforge.net/) to do this kind of testing.

Where do I start learning about GUI programming? |
|user-interface| |
I have a pretty good knowledge of programming languages like C/C++, Java, Python. But they were all mostly learnt in a college / high school class room setting where the best user interface was a numbered menu. You know, the standard data structures, implementation of various algorithms, file handling and the like.

Make sure people know, that you know, that there are problems. That there are bugs. And give them an easy way to proide feedback.
What about having a "closed beta" with the "4 or 5 users" who suggested the feature in the first place? |
You need to think of this from your user's perspective - which will cause less frustration? Buggy code is usually more frustrating than missing features. |
If it doesn't break anything else, why not ship it? It sounds like you have a good relationship with your customers, so those who want the feature will be happy to get it even if it's not all the way there, and those who don't want it won't care. Plus you'll get lots of feedback to improve it in the next release! |

In the C++ standard, Table 65 in 23.1 (Container Requirements) lists begin() and end() as requiring constant time. If your implementation violates this, it isn't conforming. |
You could a separate field that indexes the email address reversed:

Which enables you to do a query for "moc.liamg@*"

What is the best way to debug a custom ODBC driver on Windows? A former member of our team wrote the driver so we have the source available.
How do you attach a debugger to the driver? Or is it easier to just add "trace prints" to the driver to see what is going on?

Trees don't work well with SQL. If you have very (very very) few write accesses, you could change the tree implementation to use nested sets, that would make this query incredibly easy (SELECT SUM(points) FROM users where left > x and right < y, if I'm not mistaken). However, any changes on the tree require touching a ... |

It's basic, but you could stick alerts or document.write calls in when you trigger something. |
Actually your example outputs:
foo {0}
For you to output {1, 2, 3} you have to do something like:
string t = "1, 2, 3";
string v = String.Format(" foo {{{0}}}", t); ;
To put a { you use {{ and to put a } you use }}. |

The algorithms should match; if you're getting different results it may have to do with the way you're handling the keys and the text. Also keep in mind that Java characters are 2 bytes long, which C++ chars are 1 byte, so that may have something to do with it. |

Right now what I/we have tried is particles with add... |
Mixing ActiveRecord find Conditions |

I want to find records on a combination of created_on >= some date AND name IN some list of names.
For ">=" I'd have to use sql condition. For "IN" I'd have to use a hash of conditions where the key is :name and the value is the array of names.
Is there a way to combine the two? |

Using the `Iterator` interface allows any class that implements its methods to act as iterators.
