It's like saying you don't need explicit types in a dynamically-typed language. Why don't you make everything a "var" and document their types elsewhere?
It's a restriction imposed on a programmer, by a programmer. It makes it harder for you to shoot yourself in the foot; gives you less room for error. |
This is a tough situation to be in. Without knowing your particular situation (table size etc) I think that your best shot is to add an identity column, populate it and then delete according to it. You may remove the column later but I would suggest that you should keep it as it is really a good thing to have in the ta... |

You have full access to change the xslt for the content query webpart.

You could start by comparing the distance between the bounding boxes.

The most important thing to understand is that IDs have to be unique: only one element with a given ID should exist within a page. Thus, if you're wanting to refer to a specific page element, that's often the best thing to use.
If you have multiple elements that are in some way similar, you should use the elements c... |

I think use of interfaces is determined more by how many people will be using your library.

What database privileges does a Wordpress Blog really need? |
|mysql|wordpress|privileges| |
I am setting up a few Wordpress blog sites. I have created a user in mysql that wordpress will use to access its database. The docs say to give this user all privileges on the database.
Does it really need full privileges? I expect not, so does anyone know the min set of privileges that it really needs? |
Depending on your SQL flavor the following could work:

This is relative simple but a bit hard to explain since you haven't given us the way you represent your ellipse. There are so many ways to do it..

Up until about May 2008 I was using Subclipse, but due to issues with some projects, I've switched over to Subversive and am using that with no issues.

I think the best way would be to inherit BaseValidator in a new class, and pass those IDs to your control as attributes. You should be able to resolve the IDs within your validator, without knowing the full client side ID that is generated at runtime. You should get the data validating on the server first, and on the... |

Using RAISERROR like this is really not a good idea. It's just like using Exceptions as flow control logic, which is generally frowned upon.
Why not use an OUT parameter instead? That's exactly what they are for. I can't think of a database or a client API that doesn't support OUT parameters. |
Depends. On the bugs, their severity and how much effort you think it will take to fix them. On the deadline and how much you think you can stretch it. On the rest of the code and how much the client can do with it. |

Working with python interactively, it's sometimes necessary to display a result which is some arbitrarily complex data structure (like lists with embedded lists, etc.)

There's two levels of escaping: one when your code is first parsed (e.g. in case you want to include a ' inside the string), and the second in the regexp engine. So you need two \s before the $ to make the regexp engine not treat it as a special character. |

If the tests are simple, simply put them in the docstring -- most of the test frameworks for Python will be able to use that:

The SortExpression parameter specifies the name of the column to sort, followed by "ASC" or "DESC" to control the order.
You could change the DataType property of the column to specifiy a user defined type whose comparer function compares string lengths. It won't be a trivial task.

I'm no Wordpress expert, but I would recommend it does actually have all privileges apart from GRANT. It will need to be able to create tables and insert/update etc. Several plugins use their own tables, which they create on the fly if they do not exist. |
