They can help you deal with things in your life and work. That's why I have compiled 10 programming sayings. Every developer should remember them and arm themselves. 1. No w

design principle, a derived class or subclass must enhance functionality.Principle 8: Prioritize the use of composition rather than inheritanceIf possible, prioritize the use of combinations rather than inheritance. Some people may question it, but I find that the combination is much more flexible than inheritance. A combination allows you to change the behavior of a class by setting the properties of the class during run time, or by using an interface to combine a class, which provides greater

The programmer's time is precious, and the Python language is simple and elegant, but it's not that you use Python programming to be efficient. To save time and improve efficiency, there are a lot of places to pay attention to. Share with you today 10 tips from a senior Python programmer to help you save your development time significantly. 1. Do not use semicolons Using semicolons is optional in Python: U

principles: The reviewer's ability must be greater than or equal to the ability of the author of the Code, otherwise the code review becomes a training for the novice. And, in order for the censor to be really responsible, rather than perfunctory, we need to let the reviewer take primary responsibility for the reviewed code, not the author of the Code. In addition, good code review should not be done when the code is complete, but in the process of code writing, constantly iterative code review

6. Differences between HyperLink controls and LinkButton controlsFor Web visitors, the HyperLink and LinkButton controls are the same, but they still have major functional differences.When a user clicks the control, the HyperLink control will immediately "navigate" the user to the target URL, and the table pieces will not be sent back to the server. The LinkButton control first sends the table to the server, and then navigating the user to the target URL. If server-side processing is required be

Output constants and variables Code example: // The output content will wrap println ("hello, world") // The output content will not wrap print ("My name is Dash Geng") at the end ") Note: You can use the println or print

engaged in C language teaching also has a short time, in the teaching found that students in the programming has a very bad habit, is the arbitrary name, which not only to their own future reading procedures to bring inconvenience, but also to other programs to read the reader to bring trouble, more importantly, there is no uniform norms always appear to be a guerrilla, Without the feeling of the regular a

the project? What is the expected scale? How many users are there and how fast are they running? At first glance, these questions seem to have nothing to do with our programmers-but if we don't think about them well, how can we choose to develop the application framework correctly to meet these requirements? In this regard, Twitter has failed due to an underestimation of future requirements. As a result, it eventually had to abandon Ruby on Rails and

as a parameter to it, as shown below.// Set Timeout Call var timeoutid = setTimeout (function() { alert ("Hello world!" ); // Note: remove it cleartimeout (Timeoutid);Note: The code for the timeout call is executed in the global scope, so the value of this in the function points to the window object in non-strict mode, which is undefined in strict mode.2.4.2 Intermittent call setinterval ()Calling the SetInterval () method also returns an intermittent invocation ID that can be used to cance

10 harmful programming habits for development projects Avoiding these common coding habits makes our work easier, our software is safer and easier to expand. Parreto's law clearly states that 20% of results are caused by 80%. It is also known as the 80-20 rule. It applies to almost every field in which a person is needed as the labor subject. In the field of software development, this rule can be summarize

found all the errors, you have mastered the basics of PHP programming. Now I want to explain how I answered this question. Of course I also found out the above problems, but I went further. For example, have you found that strings are not enclosed by quotation marks in array indexes? Although this will not cause a serious error, it is an encoding error. In addition, have you noticed that double quotation marks instead of single quotation marks are us

10 practical skills for programmers in programming and development. Below are some simple skills and strategies I have learned at work. I hope they will be useful to you. 1. Rubber Duck debugging method I wonder if you have such an experience. When you are describing a problem to someone else, you suddenly think of a solution? There is a scientific basis for this situation. Talking about it can make our bra

10 harmful programming habits for development projects [good article for a look], good article for development projects Parreto's law clearly states that 20% of results are caused by 80%. It is also known as the 80-20 rule. It applies to almost every field in which a person is needed as the labor subject. In the field of software development, this rule can be summarized as that most problems are caused by a

1.-Dry:don ' t repeat yourself. DRY is one of the simplest laws and is the easiest to understand. But it can also be the hardest to apply (because to do so, we need to do a lot of work on generic design, which is not an easy task). It means that when we find some similar code in two or more places, we need to abstract their generality into a unique new method, and change the existing code so that they can invoke the new method with some appropriate parameters. DRY This law is probably the most

question. I have also identified the above issues, but I went further. For example, have you found that you don't enclose strings in quotes in an array index? Although this does not cause a serious error, this is a coding error. Also, did you notice that in the Echo line it uses double quotes instead of single quotes? Use the abbreviated form of the PHP start tag? And not using " After I found out the actual error, I added a comment after the problem I had identified above. This is enough to c

If it can be divisible, it indicates that this number is not a prime number, and vice versa. [Procedure 19] Question: print the case (dia

further. For example, have you found that strings are not enclosed by quotation marks in array indexes? Although this will not cause a serious error, it is an Encoding Error. In addition, have you noticed that double quotation marks instead of single quotation marks are used in the echo line? Is the PHP start sign abbreviated? " After finding out the actual error, I added a comment after the problem found above. This is enough to change the answer from "correct" to "thought-provoking", which al

1.-Dry:don ' t repeat yourself. DRY is one of the simplest laws and the easiest to understand. But it may also be the hardest to apply (because to do so, we need to make considerable effort in generic design, which is not an easy task). It means that when we find some similar code in two or more places, we need to abstract their commonalities to form a unique new method, and change the existing code to let them invoke the new method with some appropriate parameters. DRY This rule may be the mo

I will record in detail what I did every day, what problems I encountered, and how I solved these problems. Then, when I encountered a similar problem again, I would never have to "stick to my eyes with tears, but I was speechless. These notes have made me invaluable because I can use my previous experience and wisdom to solve my current probl
