iwatch series 3

This article from http://www.cnblogs.com/qianxudetianxia To be honest, the extjs series of articles are not very popular in the blog Park. Maybe there are not many people learning this stuff, however, I think this series of articles is very helpful to Chinese friends! Please support it!In the previous article, the extjs2.0 Learning Series (5) -- Ext. formpanel, w

The first two sections of this series have already covered how to configure the Ruby on Rails development environment, and now it's time to get to the point!Part1. Pre-development Preparation The main task of this time is to develop the first rails program. In particular, this time I chose a (PAAs development platform), which is the Cloud 9 platform described in the Rails tutorial, which has automatically made our environment configuration work,

, which can be used to copy mutable values such as lists or dictionaries, and not just copy references.If the list you want to copy contains a list, use the copy.deepcopy () function instead. The Deepcopy () function copies the list of colleagues inside them.>>>importcopy>>>list=[' A ', ' B ', ' C ']>>>newlist=copy.copy (list ) >>>newlist[1]=100>>>list[' A ', ' B ', ' C ']>>>newlist[' a ', 100, ' C ']>>>list=[1,2,3,[4,5,6,[7,8,9]]]>>>newlist1=copy.copy (list) >>>newlist1[

This blog mainly explains the B-tree and its insert delete operations, and gives the operation of the flowchart to achieve clear and understandable purpose, although the title is from the two-fork sorting tree to balance the binary tree and then to the Red Black Tree Series 3, no B-tree two words, but they are dynamic search tree, so I put them into a series.B-trees are a balanced search tree designed for d

Back to think MD5, through the above article, you can know, in fact, SHA-1 and MD5 is expatiating, but their respective implementation of different ways, SHA-1 in the number of operations is more compl

The Fibonacci number , also known as the Fibonacci sequence (Italian: Successione di Fibonacci), also known as the Golden Division Series, Fibonacci, Fibonacci, Fisher series, refers to such a series: 0, 1, 1, 2, 3, 5, 8, 13, 21st...... In mathematics, the Fibonacci sequence is defined as the following recursive method

After the binding is successful, the small circle is solid and saved again. Figure 3-3 bind a map control and code object Step 4: Save the project, Run "command + R", and debug "helloworld map ".

You may ask "How do we start ?", If this is the case, this chapter is a good start. If not, you have already modeled and feel good about entity splitting and inheritance, you can skip this chapter. This chapter describes the basic examples

Dynamic Planning Algorithm Author July December 31, 2010 This article is for reference: Microsoft interview 100 series V0.1 19th, 56, Introduction to algorithms, Wikipedia. OK. Let's first understand what a dynamic planning algorithm is. Dynamic Planning can only be applied to the problem of optimal sub-structure. The optimal sub-structure means that the local optimal solution can determine the global optimal solution. (For some problems, this requi
