Legal Hackintosh(tm) 

When I got my copy of MacOS X Leopard, I wondered why there have been Apple stickers included. As far as I remember, these stickers have only been distributed with new hardware. Still, the answer is provided in the license agreement:

2. Permitted License Uses and Restrictions.
A. Single Use. This License allows you to install, use and run one (1) copy of the Apple Software on a single Apple-labeled computer at a time. You agree not to install, use or run the Apple Software on any non-Apple-labeled computer, or to enable others to do so.

So, if you want to build a Hackintosh(tm), that is an ordinary PC running MacOS X, you first need to place one of the supplied Apple stickers on the front of your PC. Afterwards, you fulfill (this part of) the license requirements. That's quite similar to the Windows license stickers (but without the installation code). I still wonder if this was planned by Apple or is just a mistake.

Enhanced eEPCs 

Today was the first time in my life that I wished for eEPC (enhanced event-driven process chains) stencils for OmniGraffle. Hence, I created a simple set that you can download here. The beautiful things that you can do with them are depicted below:

I introduced two visual extensions to the eEPC notation in the example. First, I'm depicting often executed functions larger, whereas seldom used functions are shown smaller. The same holds for events, systems, and roles. Via these simple layout changes, an immediate feedback of the important parts of an eEPC is given. This is quite important, since EPCs usually fill walls. As a second extension, I also depicted the often traversed edges in the diagram in bold. This also adds to an immediate visual feedback for the viewer. In my example, I simply assumed the important parts. If you have log data or annotations available, you could even simply automatically enhance your diagram.

Dell just announced its iMac clone, the iDell(tm) XPS One. At least one point towards this machine: it only requires one cord to operate. Everything else is obvious from the picture below. The official announcement can be found here.

From above, it looks like one of Darth Vaders star cruisers:

BPEL in Practice 

Today I found a very nice article about a practical application of BPEL that I cannot hide from you:

"Process Integration of Mobile Farm Machines Using Automatically Generated BPEL Processes.

Increasing IT requirements in agriculture and farming lead to situations where mobile farm machines need to be integrated in the business processes of a farm. Since these processes and the communication partners change with the farm the farm machine works for an adapted process description must be created and used. Due to the strong variability and heterogenity of the partners Web Services and especially BPEL constitute an adequate infrastructure for the generation of such adapted business processes. Starting point for this approach is a BPEL model which serves a a template for automatic creation of an adapted concrete BPEL process."

(cited from Wirtschaftsinformatik 49 (2007) 4, S. 289-294)

The complete text is in German, but it is nevertheless worth reading it. One last citation: What do you think is a farmer doing after he gets out of his bed? Answer: The farmer first configures his IT environment using a software solution. Well done!
