Depending on just how dependency-averse you are, and what kind of text editor you're building, [GtkSourceView][1] adds undo/redo among many other things. Very worth looking at if you want some of the other [features][2] it offers.

How to skip sys.exitfunc when unhandled exceptions occur |
|python|exception| |
As you can see, even after the program should have died it speaks from the grave. Is there a way to "deregister" the exitfunction in case of exceptions?

print "Hello World!"
atexit.register(helloworld)
raise Exception("Good bye cruel world!") |
This has to be done on the server side. One thing you might look at doing is allowing all the editing to go on client side, and then in the end POST the final image (via AJAX) to the server to allow it to return it to you as the correct MIME type, and correctly packed. |

I found the problem.
The problem is that you need to set a white background on #page-container. As things stand, it has a transparent background, so the 5pt left margin on navbar-sidebanner is revealing the bg of the page_container ... so change that bg and you're cool. |
In defense of the anti-pattern designation, this code lends itself to being used in a few ways:

Dreaded iframe horizontal scroll bar can't be removed in IE? |

A major part of test-driven development that is often glossed over is the writing of testable code. It seems like some kind of a compromise at first, but you'll discover that testable code is also ultimately modular, maintainable and readable.

You're sort of mixing C and C++ ways of doing things. Why allocate more than the size of a pStruct? Why not just "new pStruct"?

What version of Oracle are you using? If its 10g or greater, you should look at using Data Pump instead of import/export anyway. I'm not 100% sure if it can handle this scenario, but I would expect it could.

No, as everyone has said, it is not strictly possible.

This is a great question.
First, don't escape text on input except to make it safe for storage (such as being put into a database). The reason for this is you want to keep what was input so you can contextually present it in different ways and places. Making changes here can compromise your later presentation.

You could perhaps override [__call or __callStatic][1] to locate a missing method at runtime, but you'd have to make up your own system for locating and calling the code. For example, you could load a "Delegate" class to handle the method call.

From what I understand, the timeout property doesn't take into account DNS timeouts. It's possible that you could make a DNS lookup separately, then make the request to the server if that works, with the correct timeout value set for the useragent.
