I had the great privilege of being a speaker at HTML5 Developer Conference in San Francisco recently.  It was the second HTML5 Dev Conf I have presented at, with the first one being October 2013.  This time, I paired with Frank Greco to present a session entitled “WebSockets: Past, Present and Future”.  Frank took the stage for the first half of the session, and I followed up with some hands-on Internet of Things (IoT) demonstrations that were integrated with Kaazing Gateway. Introducing the Tic Tac Toe Light My personal favorite demonstration was a project I called the “Tic Tac Toe Light”.  I called it this because the custom-built enclosure houses nine (9) Adafuit NeoPixels in a three-by-three (3×3) grid.  The enclosure, made using foam core board and a hot knife, also contained an Arduino Yun.  I have grown to be a big fan of the Arduino Yun for real-time IoT/web...

HTML5 WebSocket Security is Strong

This is a two-part blog post that discusses HTML5 WebSocket and security. In this, the first post, I will talk about the security benefits that come from being HTTP-compatible and the WebSocket standard itself. In the second post (coming soon) I will highlight some of the extra security capabilities that Kaazing WebSocket Gateway offers, things that real-world WebSocket applications will want to be fully secure. A WebSocket connection starts its life as an HTTP handshake, which then upgrades in-place to speak the WebSocket wire protocol. As such, many existing HTTP security mech... (more)

Kaazing WebSocket Gateway Security is Strong

This is the second post of a two-part blog post that discusses HTML5 WebSocket and security. The first post, HTML5 WebSocket Security is Strong, talked about the security benefits that derive from being HTTP-compatible and the WebSocket standard itself. In this, the second post, I will highlight some of the extra security capabilities that Kaazing WebSocket Gateway offers. Kaazing WebSocket Gateway makes your Web application architecture more secure. We leverage the HTTP and WebSocket standards as well as Kaazing-specific technology for capabilities beyond what the standard p... (more)

AjaxWorld Special: Creating AJAX and Rich Internet Components with JSF

This article is based on, and contains excerpts from, the book Pro JSF: Building Rich Internet Components by Jonas Jacobi and John Fallows, published by Apress. Book is now available on fine bookstores and Amazon as of February 25, 2006. JavaServer Faces (JSF) standardizes the server-side component model for Web application development but doesn't standardize the presentation layer at the browser. In a series of articles we are going to look at how JSF can fulfill new presentation requirements without sacrificing application developer productivity building Rich Internet Applicat... (more)
