Tour de France 2011 – Analysis using ADF DVT Graphs – Part 2 – Gap with Cadel for Top 5 throughout the stages1
This article uses the statistics about this year’s Tour de France to visualize the gap between each of the top 5 riders and Cadel Evans – throughout the 21 stages. It produces a line chart that provides easy insight in the history of this year’s event – making it abundantly clear that for example Contador never really stood a chance and only kept losing time. It also shows that Frank Schleck did very well indeed, outpacing is brother for the first 17 stages.
The chart this is created in this article looks like this:
It is fairly basic – created using only simple declarative ADF DVT settings. The greatest hurdle to overcome was the creation of a SQL Query that returns the required data in format that is easily consumed and processed by the graph.
Last night, the AMIS Mobile Special Interest Group convened. This session had as objective to explore the many different mobile agents and devices that we encounter, the types of signals, information and functions that are relevant with these various agents and the impact their inclusion in the mobile sphere of our customers has on the enterprise applications and architecture.
Our guest speaker – Rolf Hut of the Faculty of Civil Engineering and Geosciences – did an excellent job of introducing a new class of mobile agents with his presentation on hydro-meteorological stations. He even had us all build rain-sensors, from easily accessible and very cheap materials. 10 minutes of super-glueing, soldering and kindergarten-level handcrafting was all it took for 6 teams to create a sensor that could be connected to a laptop to register simple signals.
From this very practical example, it was not hard to envisage a wide network with hundreds or thousands of devices that report findings – to be processed by the backend infrastructure.

While the congrats are getting in via the usual virtual channels like Twitter and mail for being awarded the best speaker awards for the Database (Alex Nuijten) and Fusion Middleware (Luc Bors) tracks, I would like to mention that great Keynote session on Monday that was put together by the ODTUG Kaleidoscope board. The board created some hilarious movies while using these as a bridge to speak about the bit more serious topics like last years awards, “thank you”-s for the people out there that made it all work and for example the new location of Kaleidosope 2012. Via my YouTube channel you can see sketches of: “The Bachelorette”, “Big Brother” and others…
To give you a taste of what was shown:
In this blog I will show you how you can call a webservice programmatically in Java without using a webservice library like JAX-WS or Apache Axis. Normally you would use of course a webservice library, but in some cases this can be useful and quick; for example when you have problems generating a client proxy with a webservice library or if you only need some small specific parts of the SOAP response XML tree. Â It shows that a SOAP call is just XML over HTTP, from a plain piece of Java code.Â Then, I will show you an example how you can use this and make your own servlet webservice-tester like a simple SoapUI in JDeveloper 18.104.22.168.
Currently in Cary Millsap’s session about his agile approach on things called “My Case for Agile Methods“. Agile is (not yet) my thing, but knowing Cary, and he is in to it, when he is enthusiastic about something its probably one of those things which you should look into. If not even due to, as far as I know, the Agile context Cary is using is not the Agile context referred to I see being used out there. The “agile” thing out there is the one, is the one, I will joke about. But that said, a lot of methods are not bad at all, but people implement them wrongly so trying to keep an open mind, this session of Cary was more or less mandatory to get my vision about this back on track once more.
Cary also mentioned this emotion that probably mainly goes around in the DBA world. But as Cary mentioned during his presentation, “Agile is not undisciplined”, so if it gets the wrong emotional context, then is mainly due to people not doing it correctly. Could be thats it has to do with not being correctly trained in Agile or maybe incorrectly “managed”. So what is Cary’s feeling about this, that is, “Agile” as is…
Sunday’s Conference day started very early at around 07:30 by going straight to registration, then on to a quick breakfast and the first session at 08:30 AM. Joel Kallman of the APEX Development team started my round of that morning by explaining all the tools and processes which are used / were used by the APEX Development teams that is located more or less around a huge amount of different places in the US, Europe and India. Not even to mention al the supporting people on topics like security, creating manuals, testing, supporting etc, etc. Fun to see that the team uses tools like Hudson, Subversion and Oracle’s conference tooling to be able to work wherever you as a team member are located.
