Microsoft launched its own Windows 8 x86 tablet SurfacePro, which will sooner or later steal the business of other PC manufacturers. Many hardware manufacturers have begun to plot countermeasures. Dell's countermeasure is to embrace Linux. Dell has just launched Ubuntu XPS13, pre-loaded Ubuntu12.04PrecisePangolin, for $1,449, $50 cheaper than Windows. XPS is mainly intended for the consumer market, but recently DellUSA once again announced

A: PrefaceThis blog is written by a friend of mine, who wants to learn the design of the PCIe DMA controller based on the FPGA, but there is no suitable xilinx development Board on hand, and xapp1052 does not provide the simulation code to make his learning difficult. So I think, or use EDK to build a small system, and then use Modelsim to simulate the xapp1052 DMA transceiver control, this should be the most comprehensive understanding of PCIE_DMA, I hope everyone will be helpful.Second: Pre-pr

Dell XPS 12 does not take up much of the weight of the fuselage, and the 1.52 kg weight is somewhat skewed towards a 12-inch super-pole, but the aluminum-magnesium metal fuselage is a

The Spring Cloud Consul project is a service governance implementation for consul. Consul is a distributed, highly available system that contains multiple components, but as a whole, a tool for providing service discovery and service configuration for our infrastructure in the microservices architecture. It contains the following features:Service discoveryHealth CheckKey/value StorageMulti-Data centerThanks to the implementation of the spring Cloud Consul project, we can easily register spring b

general recommendation is 3 or 5 server. Deploying a single server is very bad because data loss in a failed scenario is unavoidable. This article covers the creation of a new datacenter, all other agents are running in client mode, which is a very lightweight service registration process that runs health monitoring and forwards query results to the service. The agent must be running on each node in the cluster.Consul.exe Agent-config-file Test_config.jsonLet's run an agent in server mode first
