Software Detection of Currency
Steven J. Murdoch presents some interesting results indicating that the EURion constellation may have been obsoleted:
Recent printers, scanners and image manipulation software identify images of currency, will not process the image and display an error message linking to The detection algorithm is not disclosed, however it is possible to test sample images as to whether they are identified as currency. This webpage shows an initial analysis of the algorithm's properties, based on results from the automated generation and testing of images. [...]

Initially it was thought that the "Eurion constellation" was used to identify banknotes in the newly deployed software based system, since this has been confirmed to be the technique used by colour photocopiers, and was both necessary and sufficient to prevent an item being duplicated using the photocopier tested. However further investigation showed that the detection performed by software is different from the system used in colour photocopiers, and the Eurion constellation is neither necessary nor sufficent, and in fact it probably is not even a factor.

Link without fear – Copyright in Ireland in a Digital Age
The Copyright Review Committee report has been published. Headline recommendations:

Ensure the right of free speech is a central element of the new copyright regime, including in the areas of parody and satire;
Legalise legitimate forms of copying by introducing an explicit and broadly defined “Fair Use” policy.
Ensure the extent of copyright ownership is balanced against the public good;
Design a system which is clear to all parties, including end users;
Design an enforcement mechanism which is easy to understand, transparent and accessible to all parties;
Target penalties at those who infringe on copyright rather than on third parties such as intermediaries;
Future-proof the new regime by basing it on applicable principles rather than rules relevant to today’s technology only;
Make it easy for end-users to identify and engage with owners of copyright material.

Here's hoping Sean Sherlock now does what he said he'd do, and acts on these recommendations.

Back-up Tut and other decoy spatial antiquities
I like this idea -- a complete facsimile of King Tut's burial chamber. Bldgblog comments:
“On the 90th anniversary of the discovery of King Tut’s tomb, an “authorized facsimile of the burial chamber” has been created, complete “with sarcophagus, sarcophagus lid and the missing fragment from the south wall.” The resulting duplicate, created with the help of high-res cameras and lasers, is “an exact facsimile of the burial chamber,” one that is now “being sent to Cairo by The Ministry of Tourism of Egypt.” [...]
'Interestingly, we read that this was "done under a licence to the University of Basel," which implies the very real possibility that unlicensed duplicate rooms might also someday be produced—that is, pirate interiors ripped or printed from the original data set, like building-scale "physibles," a kind of infringed architecture of object torrents taking shape as inhabitable rooms.' [...]
'In their book Anachronic Renaissance, for instance, Alexander Nagel and Christopher Wood write of what they call a long "chain of effective substitutions" or "effective surrogates for lost originals" that nonetheless reached the value and status of an icon in medieval Europe. "[O]ne might know that [these objects] were fabricated in the present or in the recent past," Nagel and Wood write, "but at the same time value them and use them as if they were very old things." They call this seeing in "substitutional terms".'
