For a while we are working on the Axon framework. One of the main components of Axon is the event store. Axon framework has a JPA based event store as well as a file based event store. Within the incubator we have also been working on the MongoDB based event store. In this blog post I am going to explain the internals of the MongoDB event store. I will also discuss some of the next steps we want to take with the mongo event store.

On my employers blog I wrote a piece about a new feature of Hippo called pipelines that can be used to create new content channels. We have created an rss feed using the standard components of Hippo combined with the Rome project. If you are interested you can read the blog post here: http://blog.dutchworks.nl/2011/12/13/embedding-rss-in-hippo-using-the-pipelines-feature/
Enough of the fun part, now seriously. JTeam has outgrown it’s name. The past year a lot has changed and a new name is the next logical step. I cannot explain this better than my CEO Steven Schuurman. If you are interested you can read his announcement here: Head over to our new website: http://www.dutchworks.nl. Help us spread the word. Hope to see you back when we write our next technical blog. On my employers blog I wrote an article about cleaning up your local maven repository. It gets polluted with old snapshot artifacts easily. It also leaves a lot of build around if you release regularly. After cleaning up your local copy you start thinking about the repository on the server. Would that also become as big as your local one? Of course. Therefore we need to clean that one up as well. In most of our projects we use Artifactory. It is nice that artifactory comes with a REST based api. The url’s can be a bit better and the content type of the response is not what I would expect. Still the documentation is good and lost of actions are possible. In this blog post I show you the basics of interacting with the REST api using groovy. Now let us shrink the repo. Continue reading Cleaning up artifactory with a groovy script Today I came across a column posted (in Dutch) on Webwereld entitled "It’s a trap!". This column is responding to the recent decision at a LibreOffice/OpenOffice Workshop to put more effort into support for Microsoft‘s proprietary OOXML format. Perhaps it is because I have been reading Pull. Perhaps it is because I have been working at a new company over the past year who are trying to address some related issues. But this column got me thinking about what the essence is of what we call documents nowadays and how this might change in the coming years. Ever looked at the space used by your maven repository? Think that this is to much? Start reading the blog post I wrote on my employers blog about a groovy script that you can use to clean your local maven repository. It removes old snapshots stored in your repo as well as old versions of artifacts. http://blog.jteam.nl/2011/08/01/cleaning-up-your-maven-repository Recently I have been doing a lot with Node.js. It is a nice server technology that enables you to program on the server like you program on the client. Wouldn’t it be nice to create a java based business logic backend but a light weight client and server backend. Communication between node.js and java is done in two ways in the sample. We use http and json for querying the data and for providing new data. Next to that I have an event system that pushes events with new data to the clients using nowjs. The following image gives you an idea about the overall solution.
If you want to find out more about this sample read on. Continue reading Combining java and Node.js through redis pub/sub and a json remote interface I am learning about Node.js. While learning I usually create a few demo’s. Another thing I am attending a training for is learning how to give good presentations. I had to prepare a 10 minute presentation. Would be nice if I could combine the learning about Node.js with the 10 minute presentation. I decided to create a Node.js application to give the presentation. So no Keynote for me this time. In this blog post I present you an additional sample, focussed on creating presentations as a programmer. I’ll use a few node.js modules: Jade, Express. On my employers blog I wrote an extensive article about Node.js, you can have a look at the article as well. http://blog.jteam.nl/2011/04/18/learning-node-js/ |

In this post I want to share something that just happened to me this week. On monday I started as usual for the past three years or so. At the end of the day I left JTeam behind and started working for Dutchworks. Ok, I am trying to be funny. It most probably is not working. Or are you smiling?
