The Socketchannel of Java NiO is the channel that connects TCP network sockets. There are two ways to create:1. Open a socketchannel and connect to a server on the network2. When Serversocketchannel receives a connection, Socketchannel creates aOpen SocketchannelSocketchannel Socketchannel = Socketchannel.open () socketchannel.connect (New Inetsocketaddress ("127.0.0.1", 8090));Close SocketchannelSocketchannel.close ();Read data from SocketchannelRead

circuit problems. In visual inspection, it is found that the peripheral element R6 surface color anomaly, has not seen the resistance, measuring its resistance to infinity. At one end of the R6 the AIC1567 's 22 feet are connected to the other end of the AIC1567 19 feet. From AIC1567 manufacturer's circuit diagram to see 22 feet (VCC) and 19 feet (Boost) is directly connected, so it is estimated that here R6 should be a small resistance of the decoupling resistor, from 0 to several ohms. As th

revolutions between the fan. 4. Fan material Because the CPU's heat is transmitted through the heatsink, and then the cooling air blowing through the fan to take away the heat of the heat sink, and the heat of the fan can be transmitted by the composition of the thermal conductivity of the material of the film decided, so the material quality of the fan on the heat conduction performance has a decisive role, For this reason, we must pay attention to the fan thermal conductivity of the heat co

???? have been looking for a LUA as the interface Development Language script framework, similar to web development, using HTML interface,LUA acts as a scripting language, Htmlayout is the choice, but its default script is not Lua, where aOpen-source framework, Htmlayout is transformed to support LUA scripting as a logical control language;???? This series of articles will be a brief analysis of the Mfcui source code, and try to transform it into its

Finally abandon Windows XP, skip Vista directly, using WINODWS 7 Beta. Not a mouse for a long time, because it takes courage. This time I dared to try the beta version of Windows again, just because it was too tempting Reasons for building change to Windows 7 system: 1, just install the system, the basic drive can not be installed separately; 2, Microsoft for the first time to the old version of the application to give good support, I have a lot of old software in hand, such as the Dark Horse

Web development, it is the stress test, it is to assess whether a product is eligible to go live on the basic standards, let us analyze how they use.Before the test, the number of ports in front of the system is changed to large, look at the default limits of the Mac ulimit -aopen files (-n) 2560 More than 2000 FD number is very small, we change him, of course, I tested, can only open 10000, Linux can open more than 6W, so: ulim

and lifecycle of the Application object, in this sense it is a container where you can configure how each of your beans is created-based on a configurable prototype (prototype), Your bean can create a separate instance or generate a new instance each time it is needed-and how they relate to each other. However, spring should not be confused with traditional heavyweight ejb containers, which are often bulky and cumbersome and difficult to use. 6. Framework Spring can configure and combine simpl
