Author's microblog: @ laobaonong's home location The importance of English is naturally beyond doubt for our coders who are highly advanced and always in line with international standards. Especially those who are ambitious and want to break into the coding farming industry, and become a potential opportunity to kill their younger siblings. mastering English is one of the most critical factors for success. Imagine holding the JSP file translated by a publishing houseThe younger brother next to y

Original Author: Jeff Atwood In the complex field of "communication", it is much more difficult to write coherent passages that can be grasped and understood by humans than to knock out a few lines of software code that does not "vomit" the interpreter or compiler. That's why--in terms of software development--all documents are probably bad. Moreover, because writing is much more difficult for people to write than for machines, the document may contin

repeatedly! But this is a bit special! The tool named "main" is generally used only once, because it has a special mission !!! It is a user's entry function! In fact, the real entry function in VC is mainCRTStartup (). It has actually done a lot of work before the main () function of the user is in the middle of mainCRTStartup! For example, you have prepared a command line, obtained the operating system version, the initialization of IO, and obtained the environment options, as well as the init

concerned with solutions that can be searched by Binary Trees Based on memory and have an ideal time complexity. That's right, but it's not important. I have been working in the software industry for 15 years. Personally, I need to carefully follow "computer programming and design art" for zero development. [NOTE 1] Don't misunderstand me-algorithms and data structures are important. However, if no one uses the software, the most perfect and correct software in the world will also be labor-inte

In this chapter we discuss the pitfalls of mitigating synchronization methods-synchronizing code blocks.1. Thinking: Synchronize the method, reduce the granularity of synchronization, synchronization to the code block2. According to the example in the previous section, we modified the code(1) The first method, the synchronization tag to move to the updated column

We know that there are usually two debugging. NET programs, the first one is Ilspy, or one is reflector, and these two small anti-compilation software are the one we have in our study of the underlying code.Sharp Small Knife ~ ~ ~, such as you see the Ilspy such interface diagram:But what!!! Used Ilspy students probably know that this hair software is not debugging Web code ... You can only debug a program such as a console with PDB symbols ... Traged

I wrote an article yesterday to learn javascript (1) Through jQuery source code. There is a method for defining Object C in it. I didn't pay too much attention to the technical details in the early days. Later, I checked the information and found that there were many clever places in it. Today I will share with you the clever 1: Functions Functions are a rare talent in javascript

.!important; attribute !important is the syntax defined by CSS1 to increase the application precedence of the specified style rule. IE does not support this syntax, and other browsers are supported by this, we can learn that the code set priority will not be executed by IE. So we can add CSS style to important, so that it can be distinguished from IE and Firefox and other browsers. Last time I looked at Mil

This is a creation in Article, where the information may have evolved or changed. Before starting a new language, you need to understand the syntax of the language ( if you have programming knowledge in other languages ), and before you start learning, let's learn about the format of Go . If you all have a unified coding style, you can make it easier to maintain someone else's code. At the same time we exe
