If your business has been following the changes in wireless networks, you should have deployed dual-band routers and client adapters. These devices can transmit encrypted data over the radio wave over a relatively close range at a speed of more than 100MB per second. However, new hardware based on near-completion 802.11AC standards is about to be launched. The device will make the company's current wireless infrastructure feel like it's stuck in honey. Although the standard organization respon

Today's resources are completely free of WebApp, and these WebApp can generate CSS3 code for the prefix of templates, gradients, and even browser properties. If you are a front-end developer, these resources can help you save a lot of time and can provide reusable source code for future projects. 1. CSS3 Generator CSS3 Generator is one of the most popular Web applications for code generation. This application has different kinds of pages for differe

Label:[2015] Many times, when we generate database documents, using some tools, the effect is not always ideal, not the content is not detailed, is the performance of the general. A lot of it is word, HTML. It's awkward to look at. I used to excel, so in my spare time, I simply wrote a database document generation tool for everyone to exchange learning, and the programmer to encourage each other.This tool is a C # console, based on Npoi, which operate

21st century is the century of the cloud, large-scale cloud networks have emerged, and in the next few years will be high-speed development, so that cloud-based systems will be more and more. If you want to develop a high-performance cloud system, server performance testing is an essential link. Today, we will introduce a new generation of server performance testing tool Gatling. One, what is Gatling Gatling is a High-performance server performance

This already means that it uses a deferred strategy to query the data.The T_customer table in the database is obviously not id=100 customer, and we are to query this customer, can try the Get/load () method respectively. The Get () method in Hibernate is also tested first. public class Hibernatetest { //test Get/load method Difference @Test public void Test1 () { Session session = Hibernateutils.opensession (); Session.begintransaction (); Operatio

There are many things worth learning about 10-ge switches. Here we mainly introduce the new technology trend of 10-ge switches. As compatible with the latest Ethernet technology, 10-Gigabit Ethernet is not just a "high-speed rebuild" of Ethernet. For the first time, 10-Gigabit Ethernet is introduced, this is the first time that a private network is integrated into a public network. As a core network device, 10-Gigabit Ethernet switches not only support 10-Gigabit access modules on existing 1-gig

The Hibernate primary key generator is used to generate the primary key for data table records. There are several common primary key generation methods.Key GeneratorPrimary key generator:First, we will introduce several common primary key generators:1) IncrementIncrement: generates an auto-increment primary key for long, short, or Int data columns.The primary key increments in numerical order. The implementation mechanism of this method is to maintain
