Something like one year ago I switched from Linux to Mac OS X. It was not an easy switch if you think that my desktop on Linux used to be this one, that is, just fvmw2 with a minimal configuration, super fast virtual desktop, border-less windows.

I wrote this article as a “master guide” to productivity. Well OK, I don't know about a "master guide" but one thing is for sure: implementing these steps will help you increase your output if you implement them towards the tasks that you’re passionate about.

Guice is a really pleasant DI framework that does its job with brilliant simplicity from a developer point of view. Guice has more than DI capabilities though, as long as you spice it up with extensions libraries. Today I'll show you the AOP capabilities that Guice offers.

One of my favorite open source tools for Java/J2EE applications is the Cron Job scheduling tool Quartz. Anyone whose ever administered Linux or a web server is probably familiar with creating and modifying cron jobs. What I like about Quartz is that its simple to use, works in both Java and J2EE server-based applications, and is easy to install.

Some of my random observations and rants about BAD managers and bosses…

With unemployment reaching and expected to surpass 10%, job security is one of the top desires of employees today.

Certain elements in HTML lend themselves to many situations when marking up a website, one of the more useful of these elements is the HTML list.

These features can help developers build new sites and applications as well as integrate new content into existing applications.

Black and white is often considered a boring, unadventurous palette, but as these examples show, that couldn't be further from the truth. Many designers find the simplicity liberating - it lets them experiment with design without the distraction of too much color. Here are some wonderful examples of black and white websites, from graceful, well-organised, typographic layouts to high-impact, maximum contrast designs.

After Canonical showed off their latest operating system, Ubuntu 9.10 (Karmic Koala), it is now time for another Linux mammoth to take the spotlight. In other words, Mandriva Linux 2010.0 was just released a few minutes ago, after two Alpha versions, one Beta and two Release Candidates, totaling more than four months of hard work. With this article, we are proud to present the new features that are included in the new Mandriva Linux release.

It's amazing to see version four of a browser which has only been available for a little over a year. Compare that to Firefox, which took over six years to reach 3.6. Perhaps it's just super smart marketing, or perhaps Chrome is putting an enormous amount of energy into the browser wars.

With daylight savings time ending today, I thought this was a good time for a post. How to handle time is one of those tricky issues where it is all too easy to get it wrong. So let's dive in. First off, using UTC (also known as Greenwich Mean Time) is many times not the correct solution. Yet many programmers think if they store everything that way, then they have it covered. (This mistake is why several years ago when Congress changed the start of DST in the U.S. you had to run a hotfix on Outlook for it to adjust reoccurring events.)

Note: The following material and presentation was prepared for students of the Indian Institute of Information Technology (IIIT), Allahabad. The aim was to get them excited about contributing to open source projects and in particular about Apache Lucene, Solr and Hadoop. The first talk was titled "Why you should contribute to Open Source" and was aimed at freshmen and has no technical content.

We developers are constantly barraged with an overflow of activities and information we don't possibly have enough time for, and we're given very little guidance on what is and isn't worthwhile. This morning on my drive to work, I was reflecting on some of the things I'm involved with, questioning the usefulness of each. Some of these activities (other than the act of coding itself) include:
