coding for idiots

From Macroscopic to microscopic understanding of coding, macroscopic and microscopic coding Macro thinking is to have a clear understanding of what we do and understand what we are pursuing. After understanding the whole, we need to have a deep understanding of what we are interested in. This is the so-called micro-thinking. The old saying "not seeking the whole, not seeking a domain" is the same. I persona

Some jQuery coding skills and jQuery coding skills Cache variableDOM traversal is expensive, so we try to cache elements that will be reused. // Bad h = fill ('height', h-20); // recommended $ element =$ ('# element'); h = element.height();$element.css ('height', h-20 ); Avoid global variablesJQuery is the same as javascript. In general, it is best to ensure that your variables are within the function scope

The implementation of FFT is quite complicated. We started to use vector and found that the space was too large. We changed it to an array or super. After deleting a few, it timed out again. The sin cos function has been called too many times. If it

Coding Coding Principles Description: The principle of encoding is explained by the code of material, but the coding principle is also applicable to the U8 system's customer code, supplier code, foreign code, employee Code, Department code, Unit code, warehouse code, various kinds of coding and any other items that ne

Introduction and comparison of common audio protocols for conference TV white PaperFirst, the digital audio principle: The sound is actually a kind of energy wave, therefore also has the frequency and the amplitude characteristic, the frequency corresponds to the time axis, the amplitude corresponds to the level axis. Usually the ear can be heard in the frequency of 20Hz to 20KHz of sound waves known as audible, less than 20Hz to become infrasound, higher than 20KHz for ultrasound, multimedia te

The overall overview of the implementation process of the genetic algorithm is as follows: 1, choose the coding strategy, convert the parameters into strings; 2, according to the population size n, randomly produces n string composition of the group; 3, according to the fitness function f=f (x) to calculate the fitness of each string; 4, according to the replication probability of the string f=f (x) Select a string to replicate, until already copied n

Directory I. Functions of coding specifications The second encoding specification is not "God of things" 3. Suggestions for coding specifications Four encoding specifications reference As software developers, we can develop low-level software, but not low-quality software. Therefore, how to implement quality assurance is one of our main concerns, while coding
