Address: http://www.sencha.com/blog/optimizing-ext-js-4-1-based-applications/ Although Sencha improves the performance of Ext JS 4.1, Application Performance Optimization Based on Ext JS is still the goal. To optimize the application performance, you usually need to modify the code based on the enhanced advantages of E

applications in a server-less way, and then develop a resilient, highly available backend system that is billed for the resources consumed by the actual run. It greatly improves the efficiency of development and operation, and reduces the operating cost.Building a server-free image Yellow Web applicationTo give you a more intuitive understanding of the serverless architecture and function workflows, we'll

To this end, Google, which attracts the world's best computer minds, has developed a large number of software tools to install computing devices. Google has its own file system called "Google File System", which is specially optimized for processing large data and can process 64 mb data blocks. More importantly, it can cope with possible disk or network faults at any time. Google's data is replica

Basecamp "s the project toggles the dim shadow around the window to make the menu area stand out. 5.

Twitter. There are even awards for the most interesting, outstanding, and informative tweets, as well as online apps that track the status of different Twitter applications. Many other sites and services, such as LinkedIn and Facebook, now allow users to update their current status in a way that mimics Twitter. In other words, it takes a short message to update the status on Facebook, and, of course, the status is usually the answer to the question

Redis is an open source API that is written in ANSI C, supports the web, can be persisted in memory, key-value databases, and provides multiple languages. From March 15, 2010 onwards, the development work of Redis is hosted by VMware. Since May 2013, the development of Redis has been sponsored by pivotal. The use of Redis database can be

[Crawler learning notes] Building of the SimHash-based deduplication module ContentSeen, simhashcontentseen Some websites on the Internet often have mirror websites (mirror), that is, the content of the two websites is the same but the Domain Name of the webpage is different. This will cause repeated crawling of the same web page crawler for multiple times. To

You can use the console. time (timeName) function to measure the execution time of a specific code or function. This feature is very useful for improving the performance of JavaScript code. Listing 9 shows an example.Listing 9. console. time () ExampleVar timeName = 'measuringtime ';Console. time (timeName); // start of the timerFor (var I = 0; I // Do somethingConsole. timeEnd (timeName); // end of the

WebSphere SMash The WebSphere SMash contains a dojo toolset that enables Ajax-based WEB front-end development using dojo. While Ajax and Dojo are not necessary for WebSphere SMash applications, by using them, we can build a more user-friendly WEB application for the user experience. Add Dojo to the WebSphere sMash a

better experiences. HTML5 is a cross-platform. It is supported by all three platforms and cannot be promoted to a certain platform. Currently, IOS also has many HTML5 WEB apps. It will take another year for HTML5 games to reach the general effects of native applications. It is estimated that many games are ready to play. I think the more impact is the emergence of HTML5-

Most WEB applications of some importance require maintenance of a session state, such as the contents of a user's shopping cart. How you manage and replicate state in a clustered server application has a significant impact on the scalability of your application. Many J2SE and Java EE Applications store state in the HttpSession provided by the Servlet API. The aut
