Java Non-blocking Servers, and What I Expect node.js to do if it is to Become Mature. Node.js is getting a lot of attention at the moment.
It's goal is to provide an easy way to build scalable network programs, e.g. build web servers. It's different, in two ways. First of all, it brings Javacript to the server. But more importantly, it's event based, rather than thread based, so relies on the OS to send it events when say a connection to the server is made, so that it can handle that request. The argument goes, that a typical web server "handles each request using a thread, which is relatively inefficient and very difficult to use. " They go on to state that "users of Node are free from worries of dead-locking the process — there are no locks.
Everyone knows that concurrent programming and management of threads in general are necessary because the world of web programming is essentially concurrent because multiple clients can access in the time, is necessary but in turn is complicated. In addition to the inherent complexity of the synchronization of shared resources, everyone knows that thread management is very costly for the operating system and resource-intensive and rarely many more than 100 threads are used, for example Tomcat 6 by default limits the maximum number of threads to 200. The problem is the standard Java servlet which bounds a thread to only one request, so that until the request terminates the thread is not free to be used to execute another request. Node.js code example (note the callback registration) Top 10 Client-Side Performance Problems in Web 2.0 Application Performance. Inspired by the Top 10 Performance Problems post which focuses on Server-Side performance problems taken from companies such as Zappos, Thomson, Monster and Novell I came up with the Top 10 Client-Side performance problems in Web 2.0 applications I’ve seen when working with our dynaTrace AJAX Edition users.
Cross-domain. Google Web Toolkit vs. Smart GWT: Which Should You Choose? - The. Andreu you've gone from merely misleading to just absurd.
Yes, there are 3 standard SmartGWT editions and one custom license package (Enterprise). Likewise, for Ext, there are GPL, commercial, OEM and custom licenses for ExtGWT, and some other licenses for related tools. The difference is, we at Isomorphic go out of our way to clearly answer every possible license question:
