But want to put in the virtual machine Ubuntu editing files can be used at the same time by the program in the Win7, but do not want to use the two systems of QQ or USB stick, you need to be able to file in the virtual machine and Win7

1. the backup function of sqlserver was used as early as possible, which can be implemented locally. ProgramCall. When the VM cannot be sent, the VM closes most of the stored procedures. You have to consider using other methods. 2. Later, I used my own stored procedure to back up the database. At that time, the VM and database were on the same machine, and OK w

32-bit system. When setting vm. min_free_kbytes, pay attention to the lowmem value. The Memory Policy in the kernel is adjusted today. One machine is a 16 GB 32-bit system with 16 GB memory. the min_free_kbytes value is set to 5% of the physical memory, that is, the memory is automatically released when it is less than 5%. Like other machines, edit sysctl. after conf, run sysctl-p. The result is a tragedy, and the server goes down immediately. If no r

Java generic parsing (03): the VM executes the generic code, java03Java generic parsing (03): executing generic code on a VMThe Java virtual machine does not have generic objects. All objects belong to common classes, and even in the early versions of generic implementations, you can compile a program that uses generics into a class file that can be run on the 1.0 virtual machine. This backward compatibility will be discarded later, therefore, if the

Docker in my eyes (1) docker, vm, lxcPreface What is docker? What can docker do? Why is docker so popular? I believe many people have this question. I also have. I think docker involves too many technologies. From the linux kernel to various cloud computing solutions, it is a little difficult for me. However, after learning about docker for a month, I still want to talk about it briefly. I hope it will be helpful for beginners of docker.Docker history
