Server database encoding format problem A recent project has two problems following deployment to the Aliyun server: 1, garbled problem. 2, Ajax PHP processing page inside the use of the Json_encode () function to return the JSON data, the data returned by the database can only be UTF8, if it is GBK JSON can not return. The discovery is the database coding format problem, the website uses the encoding format to be UTF8, the database encoding forma

css| Code | Web page Today we look at some of the introduction: How to efficiently CSS coding? One of the benefits of CSS being touted is that it reduces the size of the page, thereby shortening the download time, not just the load on the home page, but also the part of the time when the stylesheet is cached and subsequent pages are loaded. That's true, but the reduction in the home page load time is almost invisible because CSS code is often too verb

Anyone can write code! A few months of programming experience allows you to write "Running applications." Make it easy to run, but coding in the most efficient way requires more effort!You know, most programmers are writing "run code," not "efficient code." We mentioned earlier in this guide course, do you want to be your company's "Most distinguished professional"? Writing "Efficient Code" is an art that you must learn and practise.Naming conventions

character set is used, the page probably doesn't have any exceptions. However, when an ASCII HTML is used to refer to a UTF encoded CSS or JS file, you must specify the encoding of the referenced file. But confusing is, in the Taobao home page but there is a reference to the UTF file, and not the case, such as Taobao home end of the tbra-fp.js, did not specify its code, And here's tbra-fp.js is UTF8 code, fortunately this file is only English, and there is no AJAX-related code, phonemic UTF

), ADD CONSTRAINT fk_stu_tea_tid FOREIGN KEY (tid) REFERENCES teacher (TID) ); At this point, each record in the Stu_tea table is to illustrate the relationship between student and teacher tables. For example, records in the Stu_tea table: SID is 1001,tid to 2001, this indicates that the student with number 1001 has a teacher numbered 2001 Sid Tid 101 201 */* The student with number 101 has a teacher numbered 201 */ 101 202 */* The student with number 101 has a teacher numbered 202 */ 101 203 */

SOLID is the acronym for a set of best coding practices S Single Responsibility Principle O principles of openness and closure L Liskov (in-house) substitution principle I Interface Separation principle D Dependency Injection principle By applying these best practices at the same time, you can improve your code's ability to adapt to changes. But all things have to be degree, over-use although you can make your code highly adaptiv

MySQL build database or build a table will encounter the problem of choice coding, we used to be a habitual choice utf8, but in MySQL after 5.5.3 version with UTF8MB4 encoding, UTF8MB4 can save 4 bytes Unicode,mb4 is most bytes 4 of the meaning. Including emoji expressions and a lot of infrequently used Chinese characters can be stored, but also can store any new Unicode characters, extensibility good ah.The maximum character length of the UTF8 encodi

Label:A few days ago, desperately coding encountered a lot of problems, one of which is the Chinese character Program ape problem-Chinese code garbled. When I test curd the well-written DAO module, the database executes normally, but all the Chinese in the field are garbled. I tried to modify the Eclipse project by default encoding to UTF-8, trying to set the table encoding for the database ALTER TABLE type character set UTF8; is useless. I have encou

This is the HEVC coded frame diagram, and I'll write down my own understanding of the HEVC coding process for this diagram. (A lot of mistakes, in the rookie stage, look at the peer of this article can give some advice, I will be greatly appreciated) In the diagram, you can see that there are several clearly interconnected modules. Coding control, transformation quantization, inter-frame prediction (motion

ObjectiveHDFs can also support the Erasure coding feature, which will be released in Hadoop 3.0 and can be validated by the diagram:In HDFS-7285, this new feature is implemented. Since this feature is far from the release stage, it is possible that the code behind this block will be further modified, so just do a so-called pre-analysis , Help you get an idea of how the Hadoop community is doing this right now. I have not been exposed to erasure
