JSR 356 defines a Java API for WebSocket that allows for full-duplex communication between clients and servers over a single TCP connection. The API supports events for when the connection opens and closes, as well as sending and receiving messages. To use it, a developer creates an Endpoint class that handles events like OnOpen, OnClose, and OnMessage. They then create a dynamic web project with an HTML page containing form elements to send messages, and JavaScript code to open a WebSocket and send messages to the Endpoint for processing.

SPDYgavinthirlwall

SPDY is an experimental protocol developed by Google that sits on top of TCP and SSL to make web browsing faster. It addresses problems with how HTTP 1.1 handles multiple object downloads from modern websites by allowing for header compression, multiple simultaneous requests over a single connection, and server push capabilities. While browser and server support is still developing, using a SPDY gateway can provide speed improvements without requiring changes to existing web applications.

Java scriptconfusingbitsColdFusionConference

The document discusses JavaScript scoping and variable hoisting. It explains that JavaScript has function scoping rather than block scoping. Variables are scoped to the function they are declared in, rather than any surrounding blocks. It also discusses variable hoisting, where variable declarations are hoisted to the top of the function. This can cause confusion when a variable is declared within a block but then used outside that block. The key points are that variables live in the context of the function they are declared in, and variable declarations are effectively moved to the top of functions during hoisting.

Dependency Injection Why is it awesome and Why should I care?ColdFusionConference

The document discusses dependency injection (DI), a design pattern that allows classes to be flexible and organized by managing their dependencies. It explains that DI frameworks handle object creation and injection of dependencies automatically, reducing boilerplate code. This inversion of control allows default values and relationships between objects to be configured through files rather than hardcoded in code.

Dependency InjectionColdFusionConference

This document introduces dependency injection (DI), a design pattern that allows for flexible organization of classes. DI frameworks allow objects to be constructed and injected with their dependencies automatically based on configuration, avoiding hardcoded dependencies. Aspect oriented programming (AOP) allows cross-cutting concerns like logging or error handling to be defined separately from application code. Inversion of control (IOC) "flips" construction such that classes request fully initialized dependencies rather than constructing them directly. DI promotes loose coupling, testability, and flexibility in swapping implementations.
