. Compared to a knife flat, more smart and not lose the balance feeling. Foreign excellent cases we have seen a lot, however, Chinese apps in visual design, often with the Western apps can not be compared. For a variety of reasons-such as the font of the mishap, even if the dots than the original less than many, such helplessness to the Chinese apps designers have a lot of trouble. But the Jiangshan generation has talent, and let us also pay attention to the side, summed up in recen

！！！1. Calculate the unit test time when estimating and making the project plan2. Write unit test code before developmentWhen the house is built, the workers ' master walls will first be put on the line with a stake, so that the bricks can be erected straight, because the base bricks are based on this line. TDD is like this, first write the test code, just like the worker's master first pull the line with a stake, and then code the time to use this as a benchmark, write only the function code tha

Php code quality is greatly improved. For more information, see 1. do not use relative pathsWe often see: Require_once ('../lib/some_class.php '); This method has many disadvantages: It first looks for the specified php inclusion path and then finds the current directory. Therefore, excessive paths are checked. If the script is included by another script, its basic directory is changed to the directory where another script is located. Another problem

processing Residue is an optional parameter. If this parameter is not used, you can set it to null or use Preprocessor to control it. The key to the problem is to process the relationship between input and echo,That is to say, the latency between the captured signal and the playback signal must be small enough to improve the efficiency.

1. Use strings in ways that reduce performance overheadThe str1+9 completes a boxing behavior at run time, and 9.ToString () does not have a boxing behaviorStringBuilder to compensate for string boxing, but because StringBuilder does not have a defined length, the default allocation length is 16, and when the length is greater than 16 o'clock, new allocations are made. Suitable for applications where memory does not need to be allocated frequently.StringBuilder sb = new StringBuilder (a);Sb. App
