I finally did the migration to Drupal 7 for the Footnotes module this weekend. See Release notes and project page for more information.

With this release I also announced my intent to hand over the module to a new maintainer. Since I'm now increasingly active with affairs in the MySQL community, both hacking as well as other community tasks, it is prudent to not let old projects dangle without attention but to formally hand them over to fresh minds.

Dear Kettle friends,

Some time ago while I visited the nice folks from Human Inference in Arnhem, I ran into Kasper Sørensen, the lead developer of DataCleaner.

DataCleaner is an open source data quality tool released (like Kettle) under the LGPL license.  It is essentially to blame for the lack of a profiling tool inside of Kettle.  That is because having DataCleaner available to our users was enough to push the priority of having our own data profiling tool far enough down.

Kasper worked on DataCleaner pretty much in his spare time in the past.  Now that Human Inference took over the project I was expecting more frequent updates and that’s what we …

This is the final part in a series of posts about the MepSQL build system known as MepSQL Bakery. MepSQL is a (yet another) fork of the MySQL database server, with the server based on the MySQLatFacebook code and the build system based on the MariaDB build system.

In this final post I wish to draw a high level picture of the complete process of building TAR, DEB and (eventually) RPM packages from the source code. There's not much more technical details to add to the previous posts, instead I'm going to make some, shall we say "archeological", observations which imho are interesting given how the build system has evolved when being passed from one project to another. Perhaps more importantly, I will …

Hi Folks,

Now that we’re blogging again I thought I might as well continue to do so.

Today we’re reading data from MongoDB with Pentaho Data Integration.  We haven’t had a lot of requests for MongoDB support so there is no step to read from it yet.  However, it is surprisingly simple to do with the “User Defined Java Class” step.

For the following sample to work you need to be on a recent 4.2.0-M1 build.  Get it from here.

Then download mongo-2.4.jar and put it in the libext/ folder of your PDI/Kettle distribution.

Then you can read from a collection with the following “User Defined Java Class” code:

import java.math.*;
import java.util.*;
import …

This Friday at SCaLE 9x in Los Angeles, CA there will be a special build an open source cloud day teaching users how to use technologies from Cloud.com, OpenStack, Opscode and Zenoss to deploy, configure, manage and monitor infrastructure-as-a-service using open source software.

Here’s an overview of the program:

“Build a Cloud Day” will be dedicated to teaching users how to build and manage a cloud computing environment using free and open source software. The program is designed to expose attendees to the concepts and best practices around deploying …

This is the first part of many posts in a series of blog posts where I want to document how the MepSQL packages were built. By doing that, I will also end up covering the MariaDB build system (which this is based on), some of BuildBot, Amazon EC2 cloud and packaging DEBs and RPMs just in general, so it could be interesting from many perspectives. In this first part I'll simply scribble some notes about reviewing the OpenSuse Build System, Launchpad PPA service vs using your own servers and automating the builds with BuildBot.

Originally I just wanted to work on some new ideas on the automated build and QA system used by MariaDB. But since leaving Monty Program I didn't have access to any of those servers anymore, so as a first step I had to look into what alternatives there are for building binary packages for many …

After another week of hacking on MepSQL the DEB files for Ubuntu are now available.(MepSQL is my new "just a hobby" MySQL fork project.)

The Download page has instructions on how to install the packages with a simple apt-get install command. Debian packages will appear soon as they are now easy to add - I mostly just need to add new Amazon images for each.

Today, the United States Department of Commerce's National Telecommunications and Information Administration (NTIA) unveiled a new National Broadband Map, which can be viewed at BroadbandMap.gov.

The map includes more than 25 million searchable records and it incorporates crowdsourced reporting. Built entirely upon Wordpress, the map is also one of the largest implementations of open source and open data in government to date.

Importantly, the data behind the map shows that despite an increase in broadband adoption to 68%, a digital divide persists between citizens who have full access to the rich media of the 2011 Internet and those who are limited by geography or means.

The launch of a national map of broadband Internet access fulfills a Congressional mandate created by the 2009 federal stimulus, which …

This month is a special month. It’s not because of Valentines day or even the exciting day where we see groundhogs. No, this month is special because I’m have a book contest where you, the reader, get to win something free for doing absolutely nothing more than posting a comment saying that you want one of the several books I have available in the contest.

So without getting into boring details I’ll keep this short. I’ve been reviewing a lot of books lately and I think it’s time to get some books into people’s hands to enjoy themselves. This month the giveaways are all Python oriented.

So, all you have to do is take a look at the following titles and post a comment here saying that you want one of them. At the end of the month two readers will be chosen via a random list sorting python script I’ve whipped up for just this purpose. You will then get an email from the publisher who will send a brand new e-copy of the …
