For the above fusion gene, the transcription sequence is as follows: For the fusion gene, the most dire
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.

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

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
