Because as a teacher, it is impossible for every three-dimensional geometry can be standard on the blackboard to draw out, even if the sta

the most embarrassing time. You must ensure that the object is in a valid State at any time that may be called. This problem often occurs in classes defined separately by the constructor and the initialization routine (the constructor does not bring the object into the initialized State ).Once you have designed an architecture with concurrent elements, You can flexibly handle Application Deployment Methods: Standalone, client-server, or n-layer. 42.

It also gives people the impression that listening to your speech is more valuable than just downloading PowerPoint, which also gives you more time to play. 　　4. Complete understanding of your speech Comments such as "Oh, what the PPT is doing here" or "I really don't know what this ppt is saying" is not a good thing about speeches.

2013 will soon pass, and there is nothing more meaningful than to draw a full stop for 2013. This picture is inspired by the art of Blackboard typesetting. In this tutorial, we will design a stylish decorative font and render the effect of the blackboard. The whole design process is simple, but it takes time and is about 3h. First step Open the AI and create a new document. Add the text "2013" with the T

Old Gu for the first time to see the master, the mood is extremely excited. Mr. Chen came up to gently criticize Tsinghua University: "The huge Tsinghua, incredibly no one to talk about alg

CommunicationConnecting artifacts via message passing2) Event SubsystemAn implicit invocation style based on events. The system does not directly call the widget, the component's process is registered to the event, and when the event is triggered, all the artifacts registered in it are executed. Viewer mode. I think the advantage of the main event system is that the invocation is not directly associated with the call and is decoupled. 4. Virtual Machine styleTo build a running environment where

in the use of agile, although from the beginning of the use, but not very smooth, I think the reason is that the user needs can not be timely communication and feedback, the reason is the BA and development, testing people, not together, not in a time zone, Most of the time can only be written by email communication, this is obviously not an efficient way, and later the project made some improvements, that is, the development team began to have BA, the situation has been improved, So I think th

the qualification of TA. This class is also not to be late, otherwise the teacher will warn you after class, if you are late will give you fail. The rules of this class are so strict that it's very special. There are no professional and non-professional courses with such militarization management. Let's see what this course is about. In fact, the main content is to tell everyone what is good teaching, what is bad, mostly nonsense. I remember talking about education when I mentioned that a good

I have explained in detail the implementation principle of the prototype chain in the article understanding the principle of Javascript_05 _ prototype inheritance. We all know that the prototype chain is created based on objects (no objects, which prototype is used ), now let's parse the object creation process. Simple code Let's take a look at a simple piece of code: The Code is as follows: Function HumanCloning (){}HumanCloning. prototype = {Name: 'dumm
