[Modern PHP] Chapter II new features seven built-in HTTP servers Built-in HTTP server Did you know that PHP has a built-in Web server starting from 5.4.0? For PHP developers who only know to use Apache or Nginx to preview PHP pages, this is another gem that has not been explored. Although you can't use PHP's built-in Web server in a production environment, This feature is a perfect tool for local development. Whether I'm writing PHP code or not, I

I rarely wrote an article on the original blog. Today, it is a summary of my previous studies. The origin of modern operating systems, I think it is from UNIX . While UNIX Is from C Language. UNIX And C Is a natural pair. CWritten UNIX Of course there will be a small amount of assembly. While UNIX Of API Export, of course, yes C . That is to say, to use UNIX First, the ideal programming language is of course C . CThere are too many books to intro

1st: "Crossing the sea in the sky" and appreciation of the Business war 　　I. Original text and Source Original document of the ancient war of war: the standby week is idle, and the common case is fail. Overcast within the sun, not right in the sun. Sun, overcast. Original article: the defense is very strict and comprehensive, and it is often easy to relax, so that common things will not cause suspicion. Yin Ji can be used in the Yang affairs process, not the Yang affairs hostility. The yin techn

Chapter 1, policy-based Class Design If your field of knowledge is a circle, as your knowledge grows,The longer the perimeter. In other words, the greater the intersection of knowledge that you do not understand, the more ignorant you may feel. This is just a few pages.After design. It seems that a new space has been opened for itself, and C ++ can still be written like this :). This is a surprise from the first policy-based ClassDesign begins. InstitutePolicy-based design: Policy-based design,

-cultivation and the quality of completing the work. What do you think of the two pillars? This may reflect the mentality of college students. Before going out of campus to the Enterprise, we may think that program development is full of randomness, we don't need some professional terms and procedures to constrain it. Actually, it is not. In a real application, we need to deliver the developed program to the customer, instead of the teacher. We can't simply implement things that require it, we

equivalent to the estimated time consumption when the total workload is half completed. It can be seen that it is necessary to work effectively according to the scheduled time. 3. A target, determination, and estimation story: A project was originally going smoothly, and the big leaders had to leave all the staff for a one-day mobilization meeting. At the end of the meeting, the leaders enthusiastically asked everyone: do you have any confidence in completing the project on schedule? At th

(2) does not exist (3) 2147483648 (4) Optimize the outermost loop in parallel 2, It takes two to three weeks to complete, ranging from hundreds to thousands of lines of code. Few people use code management tools, most of which are completed by cooperation. The program is not easy to maintain. Earlier versions indicate that many users have not completed their jobs themselves.

performance. The server performance is measured by TPS, which has little to do with the number of user concurrency. Considering a single script, the Conversion Relationship between user concurrency Vu and TPS is Rt, which is the time for the script to complete all operations at one time. If there are m transactions in each script and N scripts in total, the total TPS is :. (Note: you have doubts about the conversion relationship) For new systems, TPS and Vu acquisition can only be evaluated

imagined. I fully agree with Mr. Yan's point of view. The Code should be reviewed and the specifications should be maintained. 4.7.5 how hard is it to read other people's code? We often complain that it is difficult to read other people's code. When writing code, do we consider how to make the code easier to read and maintain? Summarize the main points in the article: Code Compliance Tool Stick to a naming Mode Use assertions to record preconditions and postconditions) Do

: Excellent: You can avoid unnecessary disputes, take a decisive grasp of the project, and make progress faster. Lack: other Members cannot present good opinions, and the team is prone to conflicts. B) Dictatorship + consultant: Excellent: Some authoritarian users can join some external ideas. Disadvantage: no scruples on the feelings of internal team members C) democratic voting: Superior: more democratic than the first two, more comprehensive grasp of the project, and full display of th

I don't want to spend any money on games; B. Team Spirit type. I like to explore the world with my peers, reduce stress and enhance friendship. My payment tends to be outstanding; C. Easy and easy to use. I am used to traveling with others. Generally, I am not willing to pay money; Based on this, you can determine the type and bi

Modern dump technology and protection measures (II) Dynamic unpacking Another common method to deal with dump is dynamic packing. The idea is that Protector does not completely unpack the protected program, but is only part of the unpack. First, when the first unpack page is about to complete, Protector intercepts the exception and unpack the requested page, then it can delete the previous page from the memory. In this way, the image of the protected

services (such as mapreduce) requires more skills. However, it is unrealistic to hire large numbers of these highly skilled talents. Integration of traditional and modern SQL and mapreduce SQL is a very familiar model for programming experts and business analysts to query data. The charm of mapreduce lies in its ability to process complicated search queries in program solutions. What changes will happen if we combine the two? Aster has provided a

When the original event model defines an event handler, it actually adds a property to the DOM element, and when you define multiple event handlers, the previous event handler is overwritten by the latter.For example:Document.onclick = function () {Console.log (window.event.toElement)}The onclick attribute is actually defined for the Document object , so it can be called Document.onclick (); The modern event model, instead of adding attributes to Dom

The Times magazine Journal recently published the top ten most nutritious foods for modern people. The ten types of food are tomato, spinach, nuts, broccoli, oatmeal, salmon, garlic, blueberry, green tea, and red wine. A number of studies have found that tomato-containing tomatoes can significantly reduce men's chances of developing cancers such as prostate cancer. At the same time, tomatoes are also the best source of vitamin C. Therefore, the cooki
