By default, database configuration uses SQLite, which is the best choice if you're new to your database, or if you're just interested in Django. SQLite is contained in Python, so there is no need to install anything. When you start your first real project, you may want to

To use a more powerful database like PostgreSQL, avoid the pain of switching databases.

Collation: The received data and return data in a unified packaging, convenient processing of receiving and returning data, and validation of the data, through the characteristics of C # to verify token, and the time stamp of the way to uniformly handle the time format of receiving and returning.

Can read first, learn more things in school, here this point I have deep experience, in the ordinary college (not out of work), can not imagine the difficulty of finding a job

And in the school of the ease of decadent themselves, especially in this big environment (dorm playing games, classes to play mobile phones, a bit of ideas will go out, hard points: can learn the basic things (can not be denied to learn, but work, in fact, still have to look at the company)) Some people will say that they do not try to blame who, to Excuse me: Just started to work half a year compared to school three years or even four years: Which brings great influence, if it is school, then I admire you

3: Reading is not to work, go back to Reading is not playing games,

This command can pop up the first element of the list. The first element is item1, so manipulating this command returns ITEM1 and removes the element from the list, which can be interpreted as a queue.

Prototype chain is the main method to implement the prototype inheritance, the basic idea is to use the prototype to let one reference type inherit the properties and methods of another reference type.

Inheritance is implemented between two objects, which is inherited by creating an instance of supertype and assigning the instance to Subtype.prototype. The essence of implementation is to rewrite the prototype object.

The current async/await feature is not added to the ES2016 standard, but does not mean that these features will not be added to JavaScript in the future. When I wrote this article, it had reached the third draft and was developing rapidly. These features have been supported by IE edge, and it will reach the fourth edition, when the feature will be logged in to other browsers-paving the road for joining the next version of the language (see also: TC39 process).

We've heard about features for some time now, so let's go into it and see how it works. In order to be able to understand the content of this article, you need to have a deep understanding of promise and generator objects. These resources may be able to help you.

For example, in the above example, we change the HTML font-size to 32px, then the box1 style becomes 320px wide, high 64px, and the text size becomes 16px;

That is, in the development process, we simply use REM to lay out a device based on one width. Then use the JS or CSS media to change the base font-size of the HTML based on the width. Can be adapted to a variety of mobile devices.

Recently bored, in order to find something to do, it took two days to glide source code probably looked at a bit. Just beginning to see Glide's source of the mind is still relatively chaotic, because the author introduced a few concepts, and a large number of generics, if you do not understand these concepts read the code to be more painful, I did not look at the details of the implementation of the details of the things, just understand the next frame of the approximate appearance, in this article, I will introduce some key concepts in glide, and walk through the picture loading process, if you want to read the glide source, it should be somewhat helpful.

Although the diploma is important, but the individual feel the University technology second, learn how to be the focus of people (many people have a derogatory view of learning to be a person, I was originally

So feel, think that life is a fake) but after some experience and know people, I think of life: especially to be a programmer, in college to learn

is to know how to maintain a good faith between people, to know how to communicate with others, to know how to maintain a return to society, to share their own learning
