I have been studying PHP for a while, and I have always believed that the disadvantage of PHP is the poor code on the Internet, so in addition to viewing the construction of dynamic website E-75 video tutorials and computer science cs50 video tutorials from Harvard University, is to buy two books about php, author of PHP and MySQLWeb development: LukeWellingLauraThomson, and I have been studying PHP for a while, and I have always believed that the dis

Make a small game by yourself (1 ). I am a newcomer to programming and have no programming experience. I am studying programming by myself. Recently I saw cs50 In the Netease Open Course and saw a small game similar to HuaRong road displayed by the lecturer. So I decided to write it myself, it is also a consolidation of the content of the previous videos. The game forms an n-level matrix based on the input number. There is a vacant space, you can move

, because you will always be in the browser, you will not learn how to build a development environment. The little things that you learn from programming learning sites like Codecademy, even if you just want to do a small, small project, you don't know where to start. Complete the MIT Computer Introduction course (if you don't pass English: MIT Open Course: Introduction to Computer science and programming). MOOC is an effective way to learn programming. Although the language of the course is

When learning about computer basics, we mentioned that negative numbers in computers are represented by supplementary codes, but why? Even after six yearsProgramClerk, I still don't know until I read the Harvard Open Class: Computer Science cs50. In layman's terms, the supplementary code is used because: In the computer, the addition and subtraction are unified, so that (-5) + (5) can finally get 0. For example, if we use 8 bits to represent nu

Not long ago learned Python2.7.5, recently read the CS50 course introduced Python3 found that the python2.x version and the python3.x version is still a big difference. Went to the official website, the 2.x and 3.0 of the main difference for a moment, trying to do the translation, there is no understanding of the place, there are wrong places, and then continue to learn the way to correct and add it. 1. Where is the difference? Simply put: Python 2.x
