P = NP

The Clay Mathematics Institute has a standing offer of $1 million for a solution and proof to the P vs. NP problem. The relationship between the P and NP complexity classes is one of the great unsolved problems in theoretical computer science, and mathematics in general. It’s sufficiently confusing that I refer you to Google if you care for an explanation.

An apparently undaunted individual at my school stands against the common belief that P ≠ NP. While he gives no formal proof, he answers the question, prominently on the Engineering Building:

Dogville is a series of short films made between 1929 and 1931. All Dogville actors are canine, with human voices overdubbed. Via MaxFunBlog, here is a clip from the most-successful film, The Dogway Melody. Dogville is also the title of a 2003 film starring Nicole Kidman instead of dogs.


The Mu-Bot (music robot) is a robot toy with earbuds for arms.

Like the Extraterrestrial Vegetation Evaluator, Mu-Bot has an iPod-like aesthetic. It is sold by Japanese retailer AudioCubes, which also sells home planetaria, bizarre watches, and various well-designed Japanese stuff.

In Soviet Russia, Domain Registers You

The .cs top-level domain does not exist on the Internet, but it was previously used by Czechoslovakia. When Czechoslovakia split into the Czech Republic and Slovakia, each country was granted a TLD (.cz and .sk), and .cs was eventually shut down. When ISO made CS the country code for Serbia and Montenegro, Srbija i Crna Gora, the operator for the .yu domain (Yugoslavia) and the Internet Assigned Numbers Authority, which manages the DNS root, decided not to use .cs for the new country, expecting the country might split. When it did, the .rs (Serbia) and .me (Montenegro) domains were created.

While .cs has died out through political revolutions, .su lives on as the Soviet Union’s top-level domain. In what signifies both the non-death of Soviet ideology as well as Russian willingness to make a buck on the domain name money machine, even against the will of the global Internet community, .su continues to register new domains. Google indexes around 17 million sites in .su, the top results of which, for what it’s worth, are not too Soviet.
