About 10 years ago, at a local Target, they were refilling the ATM machine. I was also fascinated with the inside of the ATM, but the security guard didn't allow me to go anywhere near to the machine to see the inside. In fact, the security guard politely, but firmly asked me to leave, otherwise, he told me that he would take me away.

So, based upon what I have experienced, it's no surprise that they arrested somebody for taking the photo.

Many larger places in the world use EPICS (Experimental Physics and Industrial Control System). An experiment I am a (small) part of use EPICS for control.
It is an open source control systems frequently used for particle accelerator control and observatory telescope control. We use it slightly differently, but for what we need to do, it works very well. It is maintained primary by Advanced Photon Source at Argonne National Laboratory.

In case you are wondering, no, they don't use EPICS for LHC. They use a commercial SCADA program called PVSS (for the most part anyway).

The original article is INCREDIBLY MISLEADING! In fact, it makes me wonder if Paul Kallender knew what he was writing about.
Here is the bottom of it. 21.0 % of Japanese business currently use OSS for server, 7.6 % of Japanese business is planning to introduce OSS for server, 14.6 % of Japanese business is considering to introduce OSS for server. In the same white paper, they have the figures for USA and South Korea. According to the white paper, the figure in the US is 33.0 % currently use OSS server, 5.7 % is planning to use, and 20.6 % is considering to use. In South Korea, 21.0 % is currently using, 4.7 % is planning to use, and 12.9 % is considering.
If you don't believe me, you can read it yourself at (it's on the fourth page on this PDF): http://www.johotsusintokei.soumu.go.jp/whitepaper/ eng/WP2005/eng_pressinfo3.pdf
In short, OSS use in Japan in server market is less than that of the US! Is this supposed to be a news? I don't think so!
I thought something was wrong when I saw the headline, as I never saw any OSS machines around when I used to work in Japan. In fact, everywhere I saw, I only saw Windows machines (not even Mac back in 2002).
