Er ...... Generally, it is called a configuration file, right. Of course, that's what I call it. Let's continue with this name, which is called the Emacs configuration file. The configuration file is the most important part for us to customize and expand Emacs. Generally, the most common configuration file is =. emacs =. Of course, it can also be other files. For more information, see GNU Emacs manual. However, with the use of the day and time, more

a useful way to write, rewrite it with these macros: #define pointer(T) typeof(T *) #define array(T, N) typeof(T [N])Now the Declaration can be rewritten this way: array (pointer (char), 4) y;Thus,array (pointer (char), 4)Is the type of arrays of 4 pointerschar.

Everyone in the download a lot of free software to compile the source code, all need to use configure this command, and then Make,make install and so on, here we briefly introduce what is autoconf:1. Basic IntroductionAutoconf is a program that generates a shell script (or an explanatory script or program on another operating system) that is used to configure the source code based on the compiled environment in which it is built. To give a very simple example, such as I compile the same source o

What should I pay attention to when using open-source gnu modules in commercial projects? Recently, I was helping a company get a website. The other party proposed to add a questionnaire module, and the questionnaire form was still very complicated. I have read that the open-source system LimeSurvey can meet the requirements, but it can be changed a little bit in the interface and process. After I add this system to my website, can I modify the link i

Use GNU parted for segmentation Although you can use fdisk to quickly cut your split slot, fdisk cannot support a split slot larger than 2 TB! In this case, parted is required. Don't think you don't need 2 TB! In 2009, a single hard disk now has a capacity of up to 2 TB! If you have a built-in disk array device with the host system, using a single disk device of several TB is not impossible! So you have to learn this important tool! Parted! Parted
