网络创造未来!

看《六壮士》有感
时间：2004年9月21日  心情：激动

人生就是这样，换个角度，换个位置，本来想不通的，熬不过的，其实没什么，你看，过了之后不就是另一个好的景象吗？

看完电 影，我也觉得想到了很多，看到原来觉得做的不错的东西，其实还有很多问题；原来觉得很难受的事，其实可以明天上班时认真把它做好，想想，想好了，就马上行 动，你说对吗？

Completing Your Documentation
(PHP & MySQL For Dummies, 2nd Edition)

I'm making one last pitch here. Documenting your Web database application is essential. You start with a plan describing what the application is supposed to do. Based on your plan, you create a database design. Keep the plan and the design up to date. Often as a project moves along, changes are made. Make sure that your documentation changes to match the new decisions.

While you design your programs, associate the tasks in the application plan with the programs that you plan to write. List the programs and what each one will do. If the programs are complicated, you may want to include a brief description of how the program will perform its tasks. If this is a team effort, list who is responsible for each program. When you complete your application, you should have the following documents:

1.Application plan: Describes what the application is supposed to do, listing the tasks that it will perform

2. Database design: Describes the tables and fields that are in the database

3. Program design: Describes how the programs will do the tasks in the application plan

4. Program comments: Describe the details of how the individual program works

Pretend that it's five years in the future and you're about to do a major rewrite of your application. What will you need to know about the application in order to change it? Be sure that you include all the information that you need to know in your documentation.

Moving Information from Page to Page
(PHP & MySQL For Dummies, 2nd Edition)

With PHP, you can move information from page to page by using any of the following methods:

1.Adding information to the URL: You can add certain information to the end of the URL of the new page, and PHP will put the information into built-in arrays that you can use in the new page. This method is most appropriate when you need to pass only a small amount of information.

2.Storing information via cookies: You can store cookies- small amounts of information containing variable=value pairs -on the user's computer. After the cookie is stored, you can get it from any Web page. However, users can refuse to accept cookies. Therefore, this method only works in environments where you know for sure that the user will have cookies turned on.

3.Passing information using HTML forms: You can pass information to a specific program by using a form tag. When the user clicks the submit button, the information in the form is sent to the next program. This method is very useful when you need to collect information from users.

4.Using PHP session functions: Beginning with PHP 4, PHP functions are available that set up a user session and store session information on the server; this information can be accessed from any Web page. This method is very useful for sessions in which you expect users to view many pages.

一段有意思的签名,尽显其思想个性
来自远望IT论坛的 简单思维

    当年，哈维尔苦苦思考，后极权时代无权者的权力问题。今天，一个同样深邃的问题摆在我们面前：在互联网兴起所导致的去中心化时代，还有没有我们思想的中心？

    互 联网的出现，从根本上解决了人类信息稀缺的问题。但是，当互联网本身变成信息海洋的时候，人类不得不面临另一场新的挑战：那就是超越信息，将信息转化为知 识。在这一过程中，人的伟大又一次凸显出来。迄今为止，只有人脑对信息的搜索和鉴别才是最可靠的。互联网在经历了军事阶段、商业阶段之后，终于迎来了它的 文化阶段。
