Of course, it is best to find your own "talent", to do their favorite thing to do. See the blog about the ultimate solution of the junior and wandering-now can move; want to learn management or it aspects of the students, if you want to borrow books, can see whether the teacher has been purchase

[Java class set] _ sortedset interface notes Objectives of this chapter:Understanding the relationship between sortedset interface and set InterfaceMeasure the test taker's knowledge about common sortedset operations. 3.

environments), in general, I will use the third way, only if you want to explicitly implement the lazy loading effect will be used in the fifth way, in addition, If it involves deserializing the creation of an object I will try to implement the singleton using enumerations, but I will always ensure that my program is thread safe, and I will never use the first and second way, if there are other special needs, I may use the seventh way, after all, JDK1.5 has no problem with double-check locking.

that can recycle memory resources, and programmers don't have to worry about resource recycling, and can be recycled when an object doesn't have any references. An object that can be recycled does not necessarily have to be recycled immediately, and the GC chooses the time to recycle it. You can call Gc.collect () to have the GC reclaim immediately. The GC cannot reclaim unmanaged resources, generally implements the IDisposable interface for unmanaged resources, and then uses the Using keyword

Research on the support mode of Unicode character set Here is a test program: The discovery of Boost library support for the unicod character set seems to be in the same way as STL (and certainly not fully proven). Is the original ANSI type plus w means that this is the unicod type, such as std::string corresponding to std::wstring, recently learned to use Boos

Memcached, I decided to try this Redis today.Because Redis deployments are better than windows in a Linux environment, they are intended to be deployed in a virtual machine Ubuntu environment and then tested under Windows 8.1. Go to the official website to download Redis decompression and installation, I downloaded the 2.8.0-rc2.$ wget http://redis.googlecode.com/files/redis-2.6.15.tar.gz$ tar xzf redis-2.6.15.tar.gz$ cd redis-2.6.15$ make2.

and organizes the page according to the new HTML. The Render method uses an HtmlTextWriter object as a parameter and it displays the HTML as a Web page in the browser. There are still some modifications you can make, but they are just some of the changes on the client side. The render event can also be overloaded;8. Unload event--Unload ObjectWhen the server requests an object, it generates an inherited page object in memory, which is the class of the page, which inherits from System.Web.UI.Pag
