Objective
The common MongoDB deployment has a master, a standby, the program to connect MongoDB requires the address of the primary server and port, when the cluster deployment will have multiple server addresses need to connect, the MongoDB C # API can support simultaneous connection to multiple servers.

51 single-chip microcomputer assembly delay program algorithm detailed
In this paper, 12MHZ crystal oscillator is used as an example to explain in detail the precise algorithm of assembler delay in MCS-51 MCU.
instruction cycle, machine cycle, and clock cycle
Instruction Cycle: The time required for the CPU to execute an instruction is called the instruction cycle, which is based on the machine cycle, with different instruct
language programming.The raw data collected by the forward channel in the real-time control system are mostly fixed-point integers, such as the conversion result of A/D converter of the forward analog channel, the counting result of timer/counter, etc., are fixed-point integers. And the system of the back channel can accept the input amount is an integer, that is, the finite word error caused by quantization is unavoidable, the precision of the control of the decimal place is not accepted by th
accuracy by around 10%.
Network Structure Selection
Different network architectures also have a significant impact on detection performance. We experiment on the vid validation set: The same training data, the detection accuracy of the faster R-CNN[7] model based on the resnet101[6] is about 12% higher than the faster R-CNN model based on vgg16[8. This is the key to MSRA's success in the 2015 ILSVRC and Coco game. The first few teams this year are basically using Resnet/inception's basic networ

PCs has always been tricky, and endless application upgrades, patches, and threat updates make this work difficult. Even with web-based installation and patch management tools to ease the burden, IT departments spend too much time on the desktop, dealing with many of the problems caused by personal software, multiple versions of ActiveX controls, drivers or DLL conflicts, malware infections, improperly configured hardware, and so on. Desktop virtualization technology is expected to centralize a

About xencenter
Xencenter is a management tool for Citrix to manage xenserver. It is free of charge. After xenserver is installed, xencenter is used to manage xenserver hosts, xencenter monitors, manages, and configures virtual machines through a graphical interface. The xencenter console is installed on the desktop of a personal PC to centrally manage and configure virtual machines.
Requirements for installing xencenter:
Operating System: Windows
Analyze pvs pxe startup data packets using Wireshark Tracing
Citrix Provisioning Service uses PXE technology to start virtual machines for users.
First, the VM must be set to enable the NIC by default. The NIC sends a FIND frame through PXE bootROM in the network. The data frame contains its mac nic address. After the DHCP server receives the data frame, packets are returned to the NIC, including IP addresses, subnet masks, and gateways allocated by D
Last year, wrote an article about XenServer virtual machine suspended animation problem, http://kaiqian.blog.51cto.com/236001/1625411 interested students can see this article.Some time ago, I was asked to reflect on this problem, so the continuation of the idea did a further troubleshooting.Phenomenon: A xenserver on the normal operation of the process, a number of virtual machines into the state of the bright yellow, suspended animation, because the production environment, the administrator dir

Currently, this write caching method is only an experimental feature and only supports NT6.1 or lat
