Programmers, designers, and sysadmins doing real good for humanity and the world in their spare time

Every time I had to build such an app I struggled with passing options via command line parameters. Instead of concentrating on implementing logic, I had to create a parser, validator and so on. And in another console application I had to do the same… again and again. But thankfully it’s over. Thanks to small library by Cédric Beust, creator of well-known Java testing framework TestNG. This time he created JCommander with a motto "Because life is too short to parse command line parameters".

"A component must not execute more than 20 SQL statements". A relative new discipline to enforce these types of architectural rules is Dynamic Architectural Validation. We wrote a chapter on the best practices and show how to repurpose your existing unit and functional tests. This allows you to identify architectural regressions that have been introduced with code changes by comparing the dynamic behavior between test runs.

This section in the Painless TDD series looks at object dependencies; when you ask for more than you need, and why the "natural" choices may not always be the best ones.

There was a very interesting session at UDS by Google developer Thomas Bushnell. He talked about how Ubuntu, its derivatives and Goobuntu (Google's customized Ubuntu based distro) are used by Google developers.

A tutorial on the definition and benefits of encapsulation in Java.

The tutorial helps you get started/evaluate the web2py python framework. The various features of web2py that are covered are DAL, user authentication, CRUD operations. Once the tutorial is over you will be very comfortable with the framework.

Stop the insanity! Forget the animations, ornate templates, and other me-too gimmicks, make me a better presenter instead. A look at the web as a (future) presentation delivery platform.

You can find many resources to help you learn *what* your unit tests should be named. This post instead presents a strategy to help you focus on *when* to name--or re-name--your tests.

Solution for the Property 'submit' of object # is not a function error while submitting the form using javascript.

Developers are now being tasked with writing applications for the cloud. Although that is a simple buzzword, what does it mean to me, the developer? When developing Java Enterprise applications targeted for cloud deployment, what configuration or code changes do I need to be aware of? Will Java EE 7 make it easier? Whether you are using pure JEE or the Spring Framework, can we simply deploy our enterprise applications in the cloud? This session will give an overview of why the cloud is gaining momentum, what are the key facets that one needs to understand to deploy enterprise applications in the cloud. We will look at the differences between CloudFoundry, CloudBees, Heroku and Amazon Beanstalk. Including a demonstration of configuring an existing application and deploying it to the cloud.

MongoDB ships without graphical tools for database administration: in Unix style, the command line is the standard way to manually interact with the database. In this article we'll take a look at the console and to the translation of classical SQL queries into Mongo's model.

If you’re about to launch a new web product or you just need to improve the user experience for an existing web form, then this tutorial is for you.

Maven add jar/ dependency without install it to maven repository.

Use groovy to parse configuration file that include code snippets, context and external properties

Brendan Eich recaps the major milestones and controversies in JavaScript’s history, the performance improvements, the current work on the next version of JavaScript, ending with some demoes.

Where do you fit performance in the software development lifecycle? This innocent question carries the mind baggage of having to retrofit performance into an existing process.

Cloud Foundry is an open source PaaS cloud solution from SpringSource, the same organization behind the Spring Roo framework, a next-generation rapid application development tool for Java developers.

The Bastards Book of Ruby is an introduction to programming and its practical uses for journalists, researchers, scientists, analysts, and anyone else whose job is to seek out, make sense from, and show the hard-to-find data.

Been doing some coding with Neo4J. Pretty interesting experience so far, but one thing is for sure: being able to write seriously sophisticated code that has a large, complex model underneath it, from inside unit tests that run in a few milliseconds is, as the bloodsucking credit card commercial says, priceless. There are still a couple of challenges to consider, but the reality is with a simple custom rule (using JUnit 4), you can have an embedded database that will be ready for each test, and cleaned up after each one.

Too much of programming is intimately tied up with the tools to support the development of the software.

Simple reusable GMailJava class for sending Aysnc emails. Copy the class, change the username/password and use it in your next project. fork it on github

Aren't you already tired of listing PHP 5.4 features to colleagues and having to demonstrate them? In this article I'll include all the code samples you need to make them get a feel for the new use cases.

Here is the handy class for MooTools to get different URl parts.

I receive a lot of e-mails from web designers or presumed web designers that quoting their words are “denied for all that concerns graphic and design” and they ask me how to improve themselves and build up attractive sites without being a genius of creativity and fantasy.
