advanced Client/Server (2/3-tiers) technologies. From the perspective of software, we can analyze their origins, development prospects, and comparison of similar functional technologies. The whole book runs through an idea. It is a well-known saying with the vast majority of people in China-"no matter whether it's a black cat or a white cat, it's a good cat to catch a mouse! "-- The opposite:" Even if you can catch a mouse's black cat and white cat, it is not necessarily a good cat !". The proj

details behind it, if you plan to enter the course, you can learn it. If you do not plan it, you can skip it, at least the previous thinking and simple research can ensure that you will not hide your eyes when there is valuable information or opportunities in front of you, doing more such thinking is also of great value to the breadth of thinking. Recently I started to think that the best way to learn is to first traverse the breadth first (first, find out what and why), and then select the mos

between the left and right sides of the court. Everyone will unite to do things, this is what the Prime Minister has to do and what the Prime Minister has to do. Therefore, he must be able to support all aspects of the ship, unite him, and coordinate relations. Zhuge Liang is the only talent that has this talent. 　 But at the same time, there is a side effect, that is, Guan Yu is spoiled. However, this is not the responsibility of ZHUGE Liang alone. From Liu Bei to Zhuge Liang, to other people

often organize some training in the Department. However, the communication effect has never been very satisfactory. My colleague complained that "when other colleagues ask questions about this item, they always fail to ask ideas and have poor ability to accept new things ". However, in turn, is there a problem with the way we train ourselves? Do we know our audience. What do you want them to learn? What are they interested in? How rich are they with experience? How many details do they want? Wh

on the Internet. At this time, even hosts may be rented. However, as this article only focuses on the evolution of the architecture, therefore, it is assumed that a host has been hosted at this time, and there is a certain amount of bandwidth. At this time, because the website has certain characteristics and attracts some people to visit, you gradually find that the system is under increasing pressure and the response speed is getting slower and slower, at this time, it is obvious that the data

Char STR [10];5. char * pstr = STR;6. cout 7. cout 8. Return 0;9 .} 1. array name is not a pointer Let's first overturn the argument that "array name is Pointer" and use reverse identification. Verify that the array name is not a pointer Assume that the array name is a pointer; Then: Both pstr and STR are pointers; This is because the pointer length

. As we have already said, some useful information will be displayed on the console when kernel behavior is abnormal. The next section describes how to decode and use these messages. Although itFor beginners, it is quite obscure. The data provided by the processor is very interesting information. Generally, program errors can be identified without additional tests. Most errors of OOPS messages are null pointer references orUse other incorrect pointer values. These errors usually lead to an oops

There are everywhere "people coming from here" and we are taught not to pay too much attention to technology. Technology is indeed not the only reason for success, nor can it be too important to emphasize the importance of technology. Why do Chinese people despise technology so much? Searching on the Internet, there are everywhere "people coming from here", and they teach us not to pay too much attention to technology. Technology is

It is often said that C language statements are too complicated. Indeed, this is also one of the places where C language is criticized. However, I believe that the true criticism is not the language itself, but the disseminators. The disseminators usually have a consensus that the story should be written from a simple perspective. As a principle, I do not want to oppose it. After all, I learned the C language and went through the same process. However

Why: technology or people Wu Yu Taiyan Network Studio There are many projects that we have experienced. Generally, we have some experience, whether it is successful or failed. When analyzing the cause of success or failure, I will find that everyone is basically focused on two points: technology and people. Programmers are technical personnel, so they tend to look for technical reasons. For example, the technology is too poor, such as not using the most advanced technology, especially when enc

Unable to pass the parameter! This questionid = '". $ v ['id']."' I know that this questionid is a passed parameter. Then I found the php file and wrote the code. $id = $_GET['questionid'];print_r($id);But here I show undefined! The v ['id'] has no error and can be displayed normally. The problem arises only when questionid = '". $ v ['id. Who can tell me how to write this? Reply to discussion (solution) He is href = '# 'questionid =' ". $ v ['id']."' The method for passing p

remains in the 3x age. I am talking about namespaces and package management as follows: PHP is a lightweight feature, and now adds namespaces and package management. I hope you don't want to chew on it too much. from my big point of view, I didn't place the namespace and package management on Lavavel. besides, Lavavel won't be able to make PHP changes. Python, Node. javaScript and PHP feel that there is no comparability. after all, the design purpose is different from the original intention

Var, different subtypes such as IntVar, FloatVar, and StringVar are derived. Method 2: Struct based on C language. One field is used to identify the type, and the other field is used to store data. because the data is of various types, pointers are usually used. For example: Struct var { Int type; Void * data; }; There is no big difference between the two ideas, and they can basically meet the needs. I used the second approach in PHP and made many optimizations. In PHP, all variables correspond

speaker. if I plan to invest my time in a key technology or community, it is important that the author and culture as users overlap; Maybe it's just my personal feeling-until one day I noticed quietly that my French colleagues strongly urged Symfony to be too lazy to look at Yii, even if I put all kinds of advantages into a newbie (presumably SF) and agile development are put in the ppt. Culture is important. Yii allows me to establish a Connection with it. I care about it. to put it bluntly,
