You could also theoretically do this as a PixelBender filter, and should get significantly better performance than using a pure ActionScript 3 implementation.

There is a problem with inline - once you defined a function in a header file (which implies inline, either explicit or implicit by defining a body of a member function inside class) there is no simple way to change it without forcing your users to recompile (as opposed to relink).

This is going to give you a headache unless you define your porblem more clearly to start!

You need to duplicate your logic. SQL Server isn't very smart at columns that you've named but aren't part of the dataset in your FROM statement.
So use

The same thing could be achieved by using <code>GROUP BY</code> and a <code>JOIN</code>, and you'll be rid of the subquery. This might be faster too. |

What are you really looking to accomplish here? A modal dialog sheet is generally going to return control to the host application's event loop when it's done, and any controls on the sheet are going to end up calling actions inside the host app.

Really, it sounds like you're trying to have your inter-process communication happen at the view level, which isn't really how Cocoa generally works. Things will be much easier if you separate your layers a bit more than that.

Is there any way in the OS X Terminal to move the cursor word by word?

My guess is as follows. The PythonWin editor offers autocomplete for an object, i.e. when you type `myobject.` it offers a little popup of all the availble method names. So I think when you type `X().` it's creating an instance of `X` in the background and doing a `dir` or similar to find out the attributes of the ob... |

The only way to make it transparent to your users is to put it behind a load balanced proxy. You take one server down while you update another server. Then when you done updating you put the one you updated online and take the other one down. That's how we do it.

It's not that simple. In my experience insert/delete is used less often than find. Advantage of sorted vector is that it takes less memory and is more cache-friendly.

It depends on the situation. If the menu item has applies in the current context but isn't available because of state, it should be disabled. If the context has changed so it no longer applies, it should be removed. |
I think you are missing one very important option in your list: choose the right programming language for the job. There are many programming languages which do not have these problems, because they don't have fixed size integers. |
I haven't verified this but it seems that setting the `$HTTPS_CA_FILE` environment variable to point to your ca-bundle.crt should do the trick. (the <a href="http://search.cpan.org/perldoc?Crypt::SSLeay">Crypt::SSLeay docs</a> mentions this but is a bit light on details) |

When setting your break point, right click and you should get several options about how the break point is handled (log vars and continue, pause execution, etc)
