an abbreviation for "service", which is the data directory to be used by some network services after they are started . Common services such as WWW, FTP, and so on. For example, the Web page data required by the WWW service can be placed in the/srv/www/.Temporary file storage directory (/tmp)This is where the general user or the executing program temporarily places the file. This directory is accessible to anyone, so you need to clean it up regularly. Of course, important data cannot be placed

carefully (available libraries, resources to fix a bug or both upstream, etc.). "Does node run on Windows?"No. If you is on Windows, you need to run a Vsan (I recommend VirtualBox) with Linux. Windows support for node was planned, but don ' t hold your breath for the next few months unless the P Ort."Can I access the DOM in node?"Excellent question! No, the DOM is a browser thingy, and node's JS engine (V8) is thankfully totally separate from al

LVS is a server cluster solution based on Linux system, its goal is to create a good scalability, good reliability, high performance of a system, many commercial cluster products are based on LVS technology to achieve. The core of LVS is to load balance through a set of servers, through the front-end load scheduler, the request seamlessly dispatched to the real server, then the client is not feel. Its scalability is to join or delete nodes in the cluster to achieve, by detecting the fault of the

Just a little bit-- using C + + classes to encapsulate memory access will solve most of your troubles and benefit you for life. In the case of Windows programs, there are several main memory management methods: virtual Memory (Vsan) default

between the software packages. With dependency issues, you can choose to install the following aptitude This management tool, like aptitude and apt-get, is extremely powerful in Debian and its derivative systems to package management tools. Unlike Apt-get, aptitude is better at dealing with dependency issues, for example, when aptitude deletes a package, it deletes the packages it relies on, so that no unused packets are left in the system and the system is cleaner. To execute the installation

Invoke the findClass(String) method to find the class.As you can see from the Javadoc above, the custom ClassLoader is as good as overloading findClass .Context ClassLoaderFirst of all, Java in ClassLoader on the above mentioned four,, Bootstrap ClassLoader Ext ClassLoader System ClassLoader as well as user-defined, so is Context ClassLoad
