Microsoft is learning the power of an unsatisfied curiosity and has announced a press release today on, well, something. Windows 8 tablets? Something beginning with ARM? Or news on XBox services? At 6:30PM US EST the proverbial cat will be let out of the bag. Let's just hope that whatever it is ensure us boundless job security and an excuse for more toys.

Speaking of the cat being let out of the bag, the Code Project Members Choice awards have been announced, and the winners awarded, in person, at TechEd last week. Congratulations to the deserving winners, and thank you again those who took the time and nominate and vote in the voting forms. For a list of the winners please see the full press release.

cheers,
