The ever wonderful John Resig finally posted his totally awesome processing.js code to the web. If you haven’t seen it, you should go take a look. The Wired Compiler blog said “…this might be the most impressive thing we’ve ever seen.” And I agree, but probably not for the same reasons that they cite.

Two nights ago I had a conversation with Craig McLanahan, among others, in a slightly dubious sports bar near the JavaOne conference site. When the subject of web frameworks came up, an interesting, and probably obvious, angle emerged.

Recently I was writing a “tips and tricks” blog post that was going to focus on the idea that it is better to use an object as a “string buffer”; the idea was that by passing this object around to various functions and pushing string fragments into it, you can get better performance from a JavaScript engine. My friend and colleague Alex Russell challenged me to show him hard data supporting this hypothesis—and the results were quite eye-opening!

One of the things JavaScript libraries like jQuery, Dojo, and YUI can do for you is add support for features in the latest Web standards long before they are built into browsers. But are some libraries going too far?

They've been around for a while now: reset style sheets. They're becoming more commonplace among web designers, and even Yahoo is using a reset stylesheet of their own in their development. There are a few different viewpoints and opinions on the use of reset stylesheets, though. Do you reset?

There are some disadvantages in using string if we want to store some important information’s like password, credit card numbers, bank pins, etc for some manipulations. The following list will help you understand it better.

Since I discovered it a few years ago, I've been a big Prototype fan. It's simple, and gets the job done with a minimum of fuss. It's not without warts, of course. I still occasionally forget to put 'new' in front of Ajax.Request, and some of the Ruby-like methods share their lineage's arcane naming. When it was new, it was the best thing around, and while it now has competitors, it's certainly not lagging behind.

If you use ColdFusion (or another Java-based CFML runtime), you should be using Java. There's a reason that CF uses Java under the hood: Java is incredibly powerful. Yes the interface to Java from the CF level is cumbersome and creating hybrid CF/Java applications pretty much costs you CF's RAD capabilities, but there are some real gems in the Java libraries.

This will be the first post in a series relating to clustering ColdFusion. In this first series of posts we will be looking at clustering CF at a software level using ColdFusion 8 Enterprise. Hopefully later on, we can move to a Hardware-Software set-up with examples. I mentioned in a previous post that what I will detail is drawn from my experiences from either creating clusters for clients or working on existing clusters. There are no doubt other ways to do this. Firstly, I always create what I call a "master instance", typically the first instance which is created from a multiple-instance install. Here are some important steps from that...

There have been several blog posts recently about class-loading issues apparently linked the use of the Sun-Java 1.6 (6.0) JVM. Mark Mandel has a detailed article on this here. Before seeing this article we had been working on optimizing a ColdSpring-ModelGlue-Reactor application. We blogged our progress in this article. We thought a reality check was a good idea and ran some load tests comparing this same application performance in Java 1.5 and 1.6. Once again we observed better performance in 1.6; here are the results. These results are for a 50 Virtual User (vUser) Test for 1 hour with 8 second think time (delay between clicks) comparing Java 1 5 to 1.6. Firstly Java 1.5 Total Number of Clicks: 13,345 (0 Errors) Average Click Time of all URLs: 5,298 ms

I've been a bad boy. I was supposed to write a review of ColdFusion 8 back in October of last year, but an imminent change of job and my 10 month old boy (now sixteen months) conspired to eat up all my time to play with CF8, let alone write a review. When ever I did try to write a review I always ended up with writers block. All the blog entries, by developers far more knowledgeable and respected than I, seemed to already talk about all the great new features in this latest, and greatest, version of ColdFusion.

Clustering in particular with ColdFusion and JRun can get fairly complicated pretty fast and I urge all who are going to embark on clustering to plan out how you want to cluster and why. Another key issue is to make sure when we are creating a web application that it designed and engineered from day one with clustering in mind. I have helped so many clients who hit major problems when they start building clusters, largely because the application was too tightly coupled to the environment it is running in. Hard-coded directory paths would be a classic example. In this blog posting I wanted to illustrate an interesting concept, well two in reality, Horizontal Clustering and Vertical Clustering. Let's look at a diagram....

I presented at CF.Objective on the subject of clustering and distributing ColdFusion applications. During the presentation I pointed out a "gotcha" I have encountered many times; where I have been asked to review existing High Availability (HA) environments. It has been mentioned before in previous blog posts but I wanted to amplify it, as I believe it is very important to avoid this pitfall. Hardware clustering devices can and often do, perform two distinct functions.

Call me old-skool, but I don't like pulling in huge frameworks like Acegi for some simple authentication and authorization stuff. This post will show you how I connected Wicket security to an LDAP through JAAS. This leverages the LDAP configuration and access on the appserver level and keeps the application clean. This was done on JBoss, so YMMV on another server, but this post should help you along when you need to tweak the solution.

JavaFX.com is up and running! The problem is that it doesn’t work well on most browsers. The small fonts are unreadable when viewed in FireFox or Safari. The site takes a long time to load up. The only thing notable is the transition from one window/panel to the other. Considering almost everybody else can do this as well, I am a little confused what to look at and be impressed about

Many Open Source content management systems written in PHP want to be recongnized by the business industry as being "enterprise" ready. This is not only a mark of prestige and status but places them in a position where large companies are ready to invest in the software as a platform for their projects. Drupal is now trying making its move to be enterprise ready but has a long way to go.

JSR 277 includes modularity concepts and features for both development and deployment.
