Interesting aggregation sites for Java developers

These are some of the sites that I visit on a regular basis to stay up to date with the latest developments in our industry. This list is in no way exhaustive, but just my personal preference. Feel free to post other suggestions in the comments.

InfoQ contains a lot of articles and videos of talks at conferences. Most of the content is edited and reviewed, so you can find really high quality articles. It is a great way to discover exciting talks, conferences and new technologies.

DZone is a link aggregation site for developers. Personally I find the site a bit chaotic to browse, but their Refcardz are really handy. These Refcardz are free cheat sheets for programming languages, frameworks… that you can print out and hang on the wall next to your desk.


Have a look at the Youtube play lists of the major technology providers in the industry. Most of them regularly post tutorials and screen casts for their products. For example the Spring Developer Channel is great, but you can also subscribe to the Oracle Learning Channel for more JEE content.

Choosing the right identity

When working with databases, a problem we all face, is how to uniquely identify each new record that gets introduced into the system. Most of the time we want some kind of generated sequential number. In particular we’ll look at how an ORM can be configured to have these identifiers generated for you in a central place like the database. An ORM will hide most of the dirty details and therefore is often considered as a kind of magic box. That’s why people tend to stick to the defaults, even though this is not always the best approach and can be the cause of many headaches. This post will explain some of the different options available and their benefits, so you can at least make an informed choice instead of blindly using the defaults.
