Rails2.3 has been released. The internal version of rails2.3 has been greatly changed. For more information, see javaeye. Because I trust the rails framework too much and have not conducted a local performance test, I am eager to launch it after passing the compatibility test. This launch immediately blocked a large number of dynamic requests and carefully looked at the crash of FastCGI.Log, and Broen occurs when a large number of requests are flushed data.Pipe.

number of ports, the complexity of the structure of the switch layer, it has also been proposed to replace the traditional exchange with circuit or hybrid design, using the local traffic demand (locality), Durability and predictability. More to the extreme, host-based solutions promote direct connection to hosts. Obviously, in any case, the value of these programs depends on their load.In the study between, some recommendations could not be well evaluated because of the lack of large-scale data

"The Meaning of U" "A shining debut. 1U a new generation of servers with thickness of only "--。 This sentence is often seen recently in ads on PC servers, but what does "U" mean here? In fact, U is a unit that represents the external dimensions of the server and is an abbreviation for the units, and the detailed dimensions are determined by the American Electronics Association (EIA), the industry group. The size of the server is required to maintain the proper size of the server to be placed

data node include storing or reading blocks of data according to the name node or customer's requirements, and periodically reporting the information about their saved blocks to the name node.By default, HDFs stores three replicas for each block of data in the cluster to ensure data reliability, availability, and performance. In a large cluster, these three replicas are typically saved to data nodes in different racks to cope with two common failures: single data node failures and network failu

);Second, Uitextfield1, Uitextfield (input box): is to control the text input and display space. The frequency of Uitextfield in the app is also relatively high. The iOS system uses the virtual keyboard to implement the input, and when you click on the input box, the system automatically brings up the keyboard to facilitate further operation. When you do not need to input, you can use the retract keyboard method to
