- Development mode relies on a new browser plugin, called the GWT Developer Plugin, that makes it possible for your Java project to create a debugging bridge to any browser into which it is installed.
- multi-browser debugging,
- you can easily test browsers on operating systems different than the one on which you're developing
- use the GWT compiler's new -draftCompile flag, which speeds up compiles by skipping optimizations.
- UiBinder makes it easy to separate the visual aspects of the UI from its associated application logic.
- mix HTML and widget elements declaratively in a UiBinder XML template
- Incorporating your own custom widgets into a UiBinder template is exactly the same as using any of the built-in widgets.
- The Google Plugin for Eclipse now provides UiBinder-aware wizards, code completion, red squigglies, and refactoring to help you use UiBinder effectively.
- GWT 2.0 introduces layout panels that actually do make it possible to reliably create the layout you want.
- developer-guided code splitting.
- ClientBundle supports bundling a wide variety of resource types, including images, text, and even CSS.
- ClientBundle is also extensible.

Google python java c++ performance comparison discussion

To date, IronPython and

Jython have had to dedicate a significant portion of their engineering

resources to achieving compatibility with CPython, with relatively

little time left over for performance optimization.
One area where I believe Python (and other dynamic languages) do

particularly well is projects with lots of developers working on lots

of little subsystems, all contributing to the same codebase or the

same released binary.

compact, high-performance code. The compiler removes dead code and

rewrites and minimizes what’s left so that it downloads and runs

quickly. It also also checks syntax, variable references, and

types, and warns about common JavaScript pitfalls.
. You can use the compiler with Closure Inspector, a Firebug

extension that makes debugging the obfuscated code almost as easy as

debugging the human-readable source.

  widgets and controls, and from lower-level utilities for
  
  DOM manipulation, server communication, animation, data structures, unit
  
  testing, rich-text editing, and more.
- dynamically generating HTML. They have a simple syntax that is
  
  natural for programmers. In contrast to traditional templating
  
  systems, in which you use one big template per page, you can
  
  think of Closure Templates as small components that you compose to
  
  form your user interface.
  
  Closure Templates are implemented for both JavaScript and Java, so
  
  that you can use the same templates on both the server and client
  
  side. For the client side, Closure Templates are precompiled into
  
  efficient JavaScript.

we
needed the support for a large number of standing connections afforded by
the non-blocking I/O programming style and
epoll.
Tornado looks a bit like web.py or Google's
webapp
5 more annotations...
- tornado.web is built on our non-blocking
  HTTP server and low-level I/O modules.
- Tornado assumes requests are not asynchronous to make writing
  simple request handlers easy.
- use the tornado.web.asynchronous decorator
- You can also see the chat demo in action on FriendFeed's servers.
- When we started, we did use Twisted. In practice, I found Twisted tedious. The deferred abstraction works, but I didn't love it in practice. Likewise, the HTTP/web support in Twisted is very chaotic (see http://twistedmatrix.com/trac/wiki/WebDevelopme... - even they acknowledge this). In general, it seems like Twisted is full of demo-quality stuff, but most of the protocols have tons of bugs.

Java NIO article performance

Few have mastered NIO. For most it provides an opportunity to really get to know your debugger. “Should this buffer be flipped before I pass it to this method, or should the method flip it?”.
Projects such as
Grizzly and QuickServer provide proven, reusable non-blocking server components.
1 more annotations...
- NIO library is 30% slower even when used for _blocking_ sockets. It's apparently poorly implemented internally.
