Because of the needs of the project and debugging environment, we need to install virtual machines on the current Windows or Mac system so that we can test different project environments. For example, we install the VMware Workstation virtual machine in the common Windows system, can simulate installing the Mac or other version system's desktop environment, we can also install the VMware Fusion virtual machine in the MAC environment, Then debug the software environment that Windows requires.

When we are programming in C, a lot of library functions are used to encapsulate system calls. All system calls are implemented through the int 0x80 in a soft interrupt way,

The former middle school teacher admitted to the university can casually play, I also really casually played the university four years. People around think I may be a progressive, but only I know that I am four years of white university, and spent 2 years in the laboratory, but I have always been middle school students thinking, what teachers teach what to learn. The last 2 years of Time also took 51 to do a little thing, temperature alarm and so on. I used to want to do embedded, the result eve

In the front-end development process, the editor is necessary to use, the predecessors left us a lot of excellent editors. notepad++, EditPlus, Emacs is not suitable for front-end development, vim learning cost is too high, brackets I do not feel good, and Microsoft recently out of Visual Studio Code. In terms of the front-end range Webstrom is definitely a weapon, but after all, the software is too large, many computers run a little laborious, the other is the famous sublime Text, has now been

What I focused on in the M1 phase was the logical structure of the entire software, which was only responsible for drawing sketches using power point and providing them to the team of the program staff. Another important thing to do is to design the icon for the BUAA MOOC client.In the M2 phase, the main difference with the M1 phase is in "tools". The tools I used in the M1 phase w

I went to every conceivable online course and reported countless MOOC courses. I don't think I actually learned anything until I went to fifth place in a month's assessment. The experience gives me the impression that programming is a battle that you can never win. I began to understand that the programmers who looked normal
