First networking application I wrote in my life (OMG, it was 17 years ago) was very interesting. We were developing marine navigation system - electronica chart + connections to GPS, radars and other sensors. At some point it became obvious that one computer is not enough at least by reasons of reservation.

Today at TSSJS, I attended Cameron Purdy's keynote titled C++, Java and .NET: Lessons learned from the Internet Age, and What it means for the Cloud and Emerging Languages. His talk was a retrospective of the trade-offs compared to C++ illustrated by Java, C# and other VM-based programming languages with Garbage-Collection, scripting languages simultaneously thrived, and what this teaches...

Comparison of the Grid/Cloud Computing Frameworks (Hadoop, GridGain, Hazelcast, DAC) - Part II

klider — Fri, 19 Mar 2010 07:02:21 +0000

What would happen, if 60% of your cloud suddenly goes down? Can you rely on the 'fail-over' capabilities of the framework of your choice? What about consistency of your data? How big would be the performance impact of node failures? Continuing our experiments from the previous article, we have decided to give a try the following frameworks: Article Type: ...

Choosing a Model/Event Pattern

maxant — Fri, 19 Mar 2010 06:46:26 +0000

The following diagrams show different implementation patterns of models and corresponding events, as typically used in the UI. Depending upon your needs, you can use the following tables to decide which pattern to implement. The patterns are split into model patterns and event patterns. Not all combinations of the patterns make sense, but patterns can be combined to fulfill your unique...

Developing Rich Web Service APIs with Java

mraible — Fri, 19 Mar 2010 06:39:29 +0000

This afternoon, I attended Ryan Heaton's talk on Developing Rich Web Service APIs with Java. I've always admired Ryan's work and what he's done with Enunciate. Below are my notes from his talk. We've come a long way from the WS (SOAP) <-> EJB days. There are many tools that you can use to develop web services today. James Sugrue

Supporting Multiple Environments

simpsonjulian — Thu, 18 Mar 2010 11:54:01 +0000

One of the longest running debates I’ve watched in the Maven community over the years, is how to best support different configurations for different deployment environments (where “deployment environment” means a QA environment or staging environment – anything other than a local developer build). Some people argue simplicity over the complexity of some of the other options mentioned...

How improved hardware changed programming

piccoloprincipe — Thu, 18 Mar 2010 11:30:50 +0000

This is a follow-up to the previous post, CPUs speed and technology innovations. As we have outlined in the previous post, the memory size and computing power available to the average programmer has increased thousands of times from the first years of his art, at least in the boundaries of a single machine (network is a common bottleneck.)

Effectively Handling Exceptions in Testing Using MagicTest

Thomas Mauch — Thu, 18 Mar 2010 07:33:09 +0000

Unfortunately handling exceptions thrown by methods under test has always been cumbersome. There has been some relief in the last few months, as both JUnit and TestNG made an effort to improve the handling of error conditions: JUnit 4.7 added rules with ExpectedException as one implementation TestNG 5.10 added the attribute expectedExceptionsMessageRegExp to the @Test annotation ...

Create Your Own bit.ly Using Base58

icoloma — Thu, 18 Mar 2010 07:27:06 +0000

Following the example of bit.ly, tinyurl, owl.ly, even coca-cola has joined the short URL bandwagon. Maybe it's because of Twitter, maybe the world is focusing on mobile devices or just saving bandwidth. In any case, it's not that hard to develop your own. James Sugrue

What's Happening in the Java World?

Enterprise, Desktop, Web, Mobile, HPC, Media and Embedded. The most important thing in the Java world is the acquisition of Sun by Oracle. James is showing a slide of Duke in a fish tank with...

Getting Started With Code Generation With Xpand

Have you heard about model driven software development (MDD / MDSD) and are thinking "what's all this fuzz about models"? "Why should models help me to be more productive," might be another thought you have. People have been asking how to leverage models on and off on the web and in meetings I attended, so I thought I might share this little tutorial with you. In this...
