Attendees of this year's GDC were given an early look at Wolfenstein, the new shooter in development by id and Raven. We've previously discussed the "Veil" ability that protagonist BJ Blazkowicz uses to hide himself, and much of the coverage relates to how it affects gameplay. "Early on, Blazkowicz stumbles upon an experiment and manages to blow it up, releasing waves of ethereal blue material. The Veil seems to turn gravity on and off as Blazkowicz tries to escape the area, making for some very original gunplay. ... The folks on hand told me that the Veil would be incorporated into game's multiplayer, but wouldn't go into details." A trailer for the game is available at Joystiq, and they had this to say: "Wolfenstein's look and gameplay is dated — and not in a retro chic way. Without the Veil, the game could be mistaken for a last-gen title, so the game's success rests on how compelling this feature will be throughout an entire playthrough."

Snoskred writes with the story of a blogger who chose to remain pseudonymous, who has been outed by an Alaskan politician in his legislative newsletter. Alaska Rep. Mike Doogan had been writing bizarre emails to people who emailed him, and the Alaskan blogger "Mudflats" was one of those who called him on it. (Mudflats first began getting noticed after blogging about Sarah Palin from a local point of view.) Doogan seems to have developed a particular itch to learn who Mudflats is, and he finally found out, though he got her last name wrong, and named her in his official newsletter. The Huffington Post is one of the many outlets writing about the affair. The blogger happens to be Democrat — as is Doogan — but that is immaterial to the question of the right to anonymity in political speech. Does an American have the right to post political opinion online anonymously? May a government official breach that anonymity absent a compelling state interest?

KentuckyFC writes "Philosophers have long wondered at the profound link between mathematics and physics, but how deep does this connection go? Pretty deep according to the results of a quantum experiment exploring the nature of mathematical undecidability. Here's how: any logical system must be based on axioms, which are propositions that are defined to be true. A proposition is logically independent from these axioms if it can neither be proved nor disproved from them; mathematicians say it is undecidable. In the experiment, researchers encoded a set of axioms as quantum states. A particular measurement on this system can then be thought of as a proposition which, if undecidable, yields a random result — which is what they found. 'This sheds new light on the (mathematical) origin of quantum randomness in these measurements,' say the researchers (abstract)."

kpearson writes "Distributed.net's 8-year-old OGR-25 distributed computing project has just proven conclusively that the predicted shortest 25-mark Golomb ruler is optimal. 'The total length of the ruler is 480, with marks at positions: 0 12 29 39 72 91 146 157 160 161 166 191 207 214 258 290 316 354 372 394 396 431 459 467 480. (This ruler may alternatively be expressed in terms of the distance between those positions, which is how dnetc displays them: 12-17-10-33-19-...).' 124,387 people participated in the project and two people found the shortest ruler, one on October 10, 2007 and the other on March 24, 2008."
