There is a need for a cloud central controller to connect multiple cloud Terminal controllers with multiple sockets in a project.Because of the large number of terminals, the concurrent requirements for the whole central controller are proposed, but the process of acquiring the socket response is a continuous blocking process with performance risks. The normal runnable is not able to return processing results.The author also thinks about the scheme of using Furthertask to do asynchronous callbac

Last year, when I was insane, I bought several CC2650 Sensortag development kits on TI's website and applied for some samples. Want to play a Bluetooth communication, but from the reception of the United States, Germany sent by FedEx, but directly let them eat ash at the bottom of the tank. The more you think about it, the more uncomfortable it is, take it out and do it.Developed platform as written in table Computer WINDOWS10 8GB Development Kit

assembly, extraction of work. Then I personally feel that there is no perfect thing, flexible may need more code, and attrbibute+ model of the inflexible is not useless, at least I use down 70%-80% can cope, not to mention on attribute can also configure a variety of formatter, Of course, it is related to the structure of most of the objects I crawl. Let's get a little bit of the chapter behind it. HTTP Header, cookie settings, post usage Parsing of JSON

Random acquisition of any row of data (rownum) in the oracle database, using lerownum Recently, when reading oracle data, I learned the concept of rownum. I used to only know how to add, delete, modify, and query database tables; After seeing the concept of rownum, I suddenly thought that many business scenarios should be applicable. For example, during random a

Flume is the (JVM) process in which a host part passes an event stream from an external source to the next destination (hop).The flume source consumes an external source like a Web server passed to the event. An event emitted by an external source

first things to solve is the problem of decoupling, one of the methods in Dapper is querymultiple , which is to return a Gridreader object and then handle it. Then this Gridreader object must be used when the connection is open, so, can not directly return and then close the object, so, the form of the interface may be used to propose the processing method, or, I just think of is using func Way to handle the results. My code is as follows: Public StaticT querymultiplestringSqlObjectParam,comma

With the concept of big data growing, how to build a system that can collect massive data is put in front of everyone. How to do what you can see is the result of no blocking collection, how to quickly structure and store irregular pages, how to meet more and more data acquisition in a limited time to collect. This art

This article mainly introduces the JS Code for randomly retrieving x records of non-duplicated data from the array. If you need it, you can refer to some operations related to the array that you often encounter at work. 1.
