OSCON 2009 Presentation "Taming your Data: Practical Data Integration Solutions with Kettle" now online

I just delivered my OSCON 2009 presentation "Taming your data: Practical Data Integration Solutions with Kettle".



I think it went pretty well, and I got good responses from the audience. I did have much more material than time, and I probably should have proposed to do a tutorial instead. Maybe next year :)

Anyway, you can find the presentation and the examples on the OSCON 2009 website. The slides are available in pdf format. There's also a zip file that contains the presentation as well as the kettle sample transformations and jobs.

My OSCON 2009 Session: Taming your Data...

Yes!

Finally, it's there: In a few hours, I will be flying off to San Franscisco to attend OSCON 2009 in San Jose, California. This is the first time I'm attending, and I'm tremendously excited to be there! The sessions look very promising, and I'm looking forward to seeing some excellent speakers. I expect to learn a lot.

I'm also very proud and feel honoured to have the chance to deliver a session myself. It's called Taming Your Data: Practical Data Integration Solutions with Kettle.

Unsurprisingly, I will be talkig a lot about Kettle, a.k.a. Pentaho Data Integration. Recently, I talked about Kettle too at the MySQL user's conference, and more recently, at a MySQL university session. Those sessions were focused mainly on how Kettle can help you load a data warehouse.

But...there's much more to this tool than just data warehousing, and in this session, I will be exploring rougher grounds, like making sense of raw imdb text files, loading and generating XML, clustering and more. This session will also be much more hands on demonstration than the Sakila sessions. If you're interested and you are also attending, don't hesitate to drop by! I'm looking forward to meeting you :)

And...because the topic of the session kind of relates to my upcoming book, "Pentaho Solutions: Business Intelligence and Data Warehousing with Pentaho and MySQL" (ISBN: 978-0-470-48432-6, 600+ pages, list price $50.00), my publisher Wiley decided to throw in a litte extra. Yup, that's right - I've got discount coupons for the book, so if you are interested in picking up a copy, or if you just want to give one away to a friend or colleague, come find me at my session (or somewhere else on OSCON) and I'll make sure you'll get one. Thanks Wiley!!

Anyway - I'm hoping to meet you there: see you soon!!!

open-msp-viewer: Free XSLT utilities to render MS Project files as HTML web pages

IMPORTANT NOTICE

The old xslt-based open-msp-viewer project is no longer updated. Please find a new and much improved pure HTML version here at github: https://github.com/rpbouman/open-msp-viewer. Thank you for your interest.

Original post below

For my day job, I've been working on a few things that allow you to render Microsoft Project 2003 projects on a web page.

The code I wrote for my work is proprietary, and probably not directly useful for most people. But I figured that at least some of the work might be useful for others, so I wrote an open source version from scratch and I published that as the open-msp-viewer project on google code. If you like, check out the code and give it a spin.

It works by first saving the project in the MS Project XML format using standard MS Project functionality (Menu \ Save As..., then pick .XML) and then applying an XSLT transformation to generate HTML.

Currently, the project includes an xslt stylesheet that renders MS Project XML files as a Gantt chart. To give you a quick idea, Take a look at these screenshots:
msp1
and
msp2
The web gantt chart is rendered in a HTML 4.01 variant, CSS 2.1 and uses javascript to allow the user to collapse and/or expand individual tasks in the work breakdown structure. Currently, the HTML does not validate due to a few custom attributes I introduced to support dynamic collapsing/expanding the chart with javascript. In addition, the xslt transform process introduces the msp namespace into the result document, which results in a validation error

You can either associate the xslt stylesheet directly with the MS Project XML file, or you can use an external tool like xsltproc.

In the trunk/xml subdirectory, you can find a couple of sample projects in xml format that already have the stylesheet association. I have tested these in IE8, Chrome 2, Safari 4 and Firefox 3.5, and it works well in all these browsers. In the trunk/html directory, you'll find HTML output as created by xsltproc.

In the future, more xslt stylesheets may be added to support alternative views. Things that I think I will add soon are a resources list and a calendar view.

Enjoy, and let me know if you find a bug or would like to contribute.

WTF? Apple favicon on the Windows update site?

I just noticed the weirdest thing while visiting the windows update site:

windows-apple

As you can see, the shortcut icon is actually an Apple icon...WTF?!! I looked in the code, and this is the code that sets the favicon:
<link rel='shortcut icon' href='shared/images/banners/favicon.ico' type='image/x-icon'/>
When I navigate directly to http://update.microsoft.com/windowsupdate/v6/shared/images/banners/favicon.ico I get the normal icon, that is to say, this: .When I look with IE6, I actually see that icon as favicon...so the question is, what's up with the Apple icon in IE8?! Do I have some virus or malware that has modified IE8? I googled for the problem, but can't find any references...am I the only one? Anybody else experiencing this?

Starring Sakila: MySQL university recording, slides and materials available onMySQLForge

Hi!

Yesterday I had the honour of presenting my mini-bi/datawarehousing tutorial "Starring Sakila" for MySQL University. I did a modified version of the presentation I did together with Matt Casters at the MySQL user's conference 2009 (video available here, thanks to Sheeri). The structure of the presentation is still largely the same, although I condensed various bits, and I added practical examples of setting up the ETL process and creating a Pentaho Analysis View (OLAP pivot table) on top of a Mondrian Cube.

The slides, session recording, and materials such as SQL script, pentaho data integration jobs and transformations, and Sakila Rentals Cube for Mondrian are all available here on MySQL Forge.
