Google street view also in Denmark :)
I just found my house using street view.
It seems that most of Denmark is now available [aarhus]
BTW my car was parked with the plate numbers readble, at the time the scan was taken, but it is nice and blurred. Thanks Google :>

Teleportation of Energy
''Still, it's a clever method, and Masahiro Hotta of Japan's Tohoku University thinks it's possible to apply that method to teleporting actual energy. The key is quantum fluctuation in the energy of a particle. The very act of measuring one particle in an entangled pair necessarily adds energy to the system, he reasons, so therefore it should be possible to carefully extract that energy when one measures the second particle, without violating energy conservation, since the energy of the system as a whole remains the same.''

How to navigate a large HDD full of (say...) movies?
Suppose that you have a large HDD full with movies.
(Not that I have any ideas how that can happen...)
Is there a simple way to attach tags to them and navigate/cluster them in some useful ways (possibly with something based on the existing filesystem of the HDD)?
... and for windows XP or above?
This project looks very intersting: ''Windows File Tagger Shell Extensions'' [source], but it is still "under construction" :(
''AudioShell - ID3 tag editor shell extension ... allows you to view and edit ID3 metadata tags directly in Windows Explorer'' [source] Too bad not all video file formats support ID3 tags...
''How to read File Summary Information [in Delphi]'' [source]
Interestingly some people talk about using keywords in XP or even tags of Windows7:
''In XP I was able to edit the meta data in almost any file and place "keywords" even on PDF files. Windows 7 has done away with "keywords" and gone to "tags". I like this system better but what I find horribly frustrating is that there are many file types to which I cannot add "tags".''[source]

Ipad VS Ideapad
"A large, high-resolution LED-backlit IPS display. An incredibly responsive Multi-Touch screen. And an amazingly powerful Apple-designed chip. All in a design that’s thin and light enough to take anywhere. iPad isn’t just the best device of its kind. It’s a whole new kind of device." [source]

Anthony Atala on growing new organs
''Anthony Atala's state-of-the-art lab grows human organs -- from muscles to blood vessels to bladders, and more. At TEDMED, he shows footage of his bio-engineers working with some of its sci-fi gizmos, including an oven-like bioreactor (preheat to 98.6 F) and a machine that "prints" human tissue.'' [video]

Give me a break!
One way or another we are screwed :(
"Record cold winter may increase ozone hole over North Europe" [source]
"European scientists confirmed that Arctic high atmosphere is reaching the lowest ever temperatures this winter, warning that destruction of the protective ozone layer is substantially increased under very cold conditions."
Furthermore:
"“The Arctic has experienced an extremely harsh winter. The first signs of ozone loss have now been observed, and large ozone losses are expected to occur if the cold conditions persist”, says European Commissioner for Science and Research Janez Potonik."
Ps But the ozone hole was it not over south pole?
Pps Funny how global warming can co-exist with "extremely harsh winter" :>

DIY paper ENIGMA replica!

Did we fix it? (from BBC)
Climate change dominates the agenda now, but what happened to the environmental causes of the 1970s, 80s and 90s - have these all been resolved now?

The "Hockey Stick" controversy
A quasi-global instrumental temperature record exists from approximately 1850. However, to construct a millennial-scale record, proxies for temperature are required. Consequently, there are issues concerning the accuracy with which these proxies reflect actual temperature change, their geographical coverage, and the statistical methods used to combine them. [source]
... The hockey stick controversy has to a large extent been focused on Mann and on the MBH98 reconstruction on which he was the lead author. ...
... In 2003, Stephen McIntyre and Ross McKitrick published "Corrections to the Mann et al. (1998) Proxy Data Base and Northern Hemisphere Average Temperature Series" in the journal Energy and Environment 14(6) 751-772, raising concerns about their ability to reproduce the results of MBH. ...
The claim
"... a rapid warming during the 20th century that culminates in anomalous late 20th century warmth ... " [source and source]
Problems replicating the results:
The M&M Project: Replication Analysis of the Mann et al. Hockey Stick [source]
... If the flawed bristlecone pine series are removed, the hockey stick disappears regardless of how the PCs are calculated and regardless of how many are included. The hockey stick shape is not global, it is a local phenomenon associated with eccentric proxies. Mann discovered this long ago and never reported it. ... [source]
Below are the findings and conclusions of the 2 third-parties that were asked to asses the validity of the original claim: The Wegman Panel and the National Academy of Sciences.
Some findings [source]:
Findings
In general, we found MBH98 and MBH99 to be somewhat obscure and incomplete and the criticisms of MM03/05a/05b to be valid and compelling. We also comment that they were attempting to draw attention to the discrepancies in MBH98 and MBH99, and not to do paleoclimatic temperature reconstruction. Normally, one would try to select a calibration dataset that is representative of the entire dataset. The 1902-1995 data is not fully appropriate for calibration and leads to a misuse in principal component analysis. However, the reasons for setting 1902-1995 as the calibration point presented in the narrative of MBH98 sounds reasonable, and the error may be easily overlooked by someone not trained in statistical methodology. We note that there is no evidence that Dr. Mann or any of the other authors in paleoclimatology studies have had significant interactions with mainstream statisticians.
Moreover [source]:
... they found that the full amplitude of century-to-century variations were underestimated to an increasing degree as the noise level was increased. Thus, the reconstruction of century-long trends has substantial uncertainty when it is based on data that exhibit year-to-year variability.
...
Some of these criticisms are more relevant than others, but taken together, they are an important aspect of a more general finding of this committee, which is that uncertainties of the published reconstructions have been underestimated.
In conclusion
As a good friend of mine said a few days ago about this controversy, it is never a good idea to mix science and politics ;)
