Bug caused by using changeable value as the default in "python method overload"​
In python we can set the passed in parameter's default value to make the function has the same running feature as the method overload in Java. Define a function like this: def testFunction(self, param1, param2=None, param3=None): Normally we use "None" as the parameter's default value. We can also use str/bool as the default value, but is it OK we use empty list [] as its default value? This is our test program: """ A test program using empty list as the passed-in parameter's default value. ...

Preprocessor magic:Default Arguments in C
This post is for programmers who like C or for one reason or another can't use anything else but C in one of their projects. The advantages of having default arguments is not something that needs convincing. It's just very nice and convenient to have them. C++ offers the ability to define them but C under the C99 standard has no way to allow it. In this post I will detail two ways I know of implementing default arguments in C. If a reader happens to know additional ways please share in ...

JavaScript cross domain request solution
1. What is cross domain? We may often using AJAX to request data from other domain, now we will have cross domain request issues. It's because JavaScript only allows to request data from the same domain because of security consideration. In short, same domain strategy means a piece of code can read data from the same source, the same source here means the combination of the same domain, protocol and port number. For example: URLDescriptionAllow communication? http://www.a.com/a.js http:/...

The Death Of The Spec
Earlier today, my colleague Matt Burns wrote a post noting that most tablet makers may be largely failing because they’ve sold their soul to Android and are now just in the middle of a spec war, which no one can win. I’m gonna go one step further in that line of thinking: the spec is dead.There have been a few key stories from the past couple of weeks that highlight this new reality. Barnes & Noble unveiled the new Nook Tablet. Consumer Reports looked at the...

Simple PHP paging class
Frequently in our web applications, we may have many records in the database to display. In order to imrpove loading speed and efficiency, we may need to display some records at a time, so we need to paginate the records. For example, if we have 1 million book records and when users want to view the book list, it's inefficient to display all the records on the same page, we may need to have some pagination to allow displaying a portion of the records such as 20 records per page. This is a simple...
