holidays over, for now
Today was the last day of vacation. I spent two weeks off where I did only what goes through my head.
today, to close with dignity the holidays, I went by boat on Lake Maggiore.
I learned that the boat is a hobby costosetto but it's cool, as you can see from the photo.
Thanks to Mat for the hospitality on the boat. Mat is great. And now I owe him a lunch or dinner.
The next time we take a boat (er) women.

HDCP with the Mac Mini
long I do not write on the blog, a bit 'to the demands of work, a little' for lack of new topics delicious.
Today I talk about phenomenology 's HDCP , the last non-latest technological invention to ensure that digital content arrive intact to your peripherals such as LCD screens and so on. " (This is the version of marketing). In fact HDCP is to prevent that, between two devices that interact through a digital signal, someone can intercept the signal and produce identical copies of the original.
For example: I just bought a Samsung SyncMaster 2032MW monitor, complete with HDCP compatible DVI input. If I connect my PC with DVI output and if I could intercept the signal Trasi, theoretically I could to skip guards present and future of any high definition sources, from DVD and all its systems of protection from unauthorized copying.
The new monitor but I connected the Mac Mini, which has DVI but not HDCP compatible. It can be seen, however, and it is perfect. What's the catch?
Simple: just wait a few minutes and, if the monitor realize that the video source is sending an animation (so potentially material covered by copyright), the image disappears unceremoniously.
The waiting time varies depending on the DVD or any type of input signal: it can vary from a maximum of 10 minutes to be instantaneous (DVD of Terminator 3, obviously original). No problem on entry
VGA.
The logical conclusion, in my experience these days is that someone took to write code specifically to recognize the animations in the presence of a non-HDCP signal.
If the monitor systematically refused to view any non-HDCP signal, I could not see anything, but do so only on certain occasions.
From a commercial perspective, however, would be worse: customers not buy the monitor in its entirety, so instead they are more likely to accept a compromise.
fact I knew this kind of limitations (absent signal completely connected with the Mini DVI to entry, no problem with the VGA cable) so I went with the Mini to the supermarket to test the monitor before purchasing, and it seemed to work.
The monitor is still spectacular. Mini is connected to the impressive image quality and the laptop connected via VGA input allows you to view HD movies with a realism never seen (at least to me :-)).
In this way, if your monitor is large enough and powerful enough PC and a fast internet connection, I note the site http://www.thehdweb.com/ that allows you to obtain a complete picture of 'high definition.
PS: do not link more link to Italian because, in addition to being almost always incomplete or very poor compared to the English version is also very unreliable and sometimes even biased on certain issues as "political."
