When developing programs, we will inevitably encounter errors and exceptions. How to quickly find the cause of the error, analyze the cause of the error, and find a solution to the problem is a problem that many junior programmers are troubled by. This is also a valuable experience. Below I will briefly introduce debugging in Visual Studio and some advanced debugging an
used for remote access, you need to deploy corresponding security solutions for cloud access points.
Server-DDoS security threats: to improve the reliability and efficiency of the virtual desktop system, enterprises often adopt multi-physical servers for virtualization deployment. In this deployment mode, the server is vulnerable to distributed denial of service (DDoS) attacks ). Therefore, when building a virtual platform, enterprises must deploy high-performance security control components on
Balancing method in LVs.IP load Balancing can be used with hardware devices or software implementations. The main products of hardware equipment is F5-BIG-IP-GTM (abbreviation F5), software products are mainly LVs, HAProxy, NginX. Which LVs, Haproxy can work on the 4-7 floor, nginx work on the 7 floor. For a simple comparison of the three, you can refer to here.Hardware load balancing devices can make the

Basic compiler skills: F10: single-step debugging, step-by-step execution of the program, generally used to view the program execution process, if the program is broken from it, you can use single-step debugging. F9: When a breakpoint is set, the program stops when it is executed to the place where the breakpoint is set. F5: run the debugging program, Debug | Go. F11: Enter the block for debugging. Ctrl + F5
combinations are directly supported by BIOS in any environment, and some key combinations require additional software support in the operating system to be effective.
Most FN combinations are implemented using the FN key plus ESC or the F1~F12 key, but there are some vendors (such as IBM, Compaq, and Sony) that have a combination of the FN key and the letter key, and most of these combinations are "secret" to the average user: Below we will also share these special key combinations.

Lua provides source code for compilation by users. You can compile it into a static library or a dynamic library. However, Lua does not provide engineering files and needs to be added by the user. This is inconvenient for new users.
I. Lua static library
Compiling to a static library is simple. Someone has already written it. The following is an excerpt:
Lua includes core lib and standard Lib. For details, refer to the document. For simplicity, we put it in a Lib. We need to createStat
