Or at least somewhere very close to the teen idol: Some Twitter users report that they are located “in Justin Biebers heart” or “Bieberacademy” or “Bieberville, California.” That comes from a new study from the august Palo Alto Research Center, which had an intern comb through the “Location” fields on 10,000 Twitter user profiles.

The PARC report says that 66 percent of users filled in the field with “valid” information. Another 18 percent left it blank altogether, and 16 percent used it to make a joke and/or an expression of their Bieberlove.

But even that 66 percent number is a bit misleading, since “valid” is a very vague term. Check out this great deadpan:

This includes those who merely entered their continent and, more commonly, those who entered geographic information in highly vernacular forms. For example, one user wrote that s/he is from “kcmo–call da po po”. Our coders were able to determine this user meant “Kansas City, Missouri”, and thus this entry was rated as valid geographic information (indicating a location at a city scale).

Big picture: The PARC report explains convincingly that you shouldn’t take the self-reported geographic information in Twitter profiles at face value. And, I’d argue, that extends to the rest of the information as well. On the other hand, if you’re an advertiser trying to find a lot of Justin Bieber fans, this stuff may be very, very useful.

(Thanks to YouTube’s Hunter Walk for the tip. Via Twitter, of course.)

Recently, there was an event in Silicon Valley to celebrate the 40th anniversary of PARC, the pioneering research facility that birthed a lot of tech’s most potent innovations.

Ever heard of laser printing or Ethernet networking or the graphical user interface?

Yes, that and much more.

PARC, by the way, stands for Palo Alto Research Center and is a wholly owned subsidiary of Xerox (XRX).

Here are some videos from the celebration, including an alumni panel, as well as predictions for 40 years hence:

“Mr. Papermaster’s employment by Apple is a violation of his agreement with IBM against working for a competitor should he leave IBM,” said Fred McNeese, director of IBM’s corporate media relations group. “We will vigorously pursue this case in court.”

And for good reason. As a member of the IBM (IBM) elite Integration and Values Team, Papermaster had broad access to the company’s intellectual property, trade secrets, and more. From the complaint:

The I&VT is charged with addressing the most difficult and important issues facing IBM, such as developing corporate strategy and driving innovation and growth and I&VT team members work with the most sensitive strategic information the Company possesses.

In his capacity as a member of the I&VT, Mr. Papermaster has gained access to confidential information concerning the Company’s strategic plans, marketing plans and long-term business opportunities, including the development of specific IBM products.

… Mr. Papermaster is IBM’s top expert in ‘Power’ architecture and technology, and he is privy to a whole host of trade secrets and confidences belonging to IBM that the company uses to design, develop and manufacture its products.”

Sounds like IBM has a lot to lose in Papermaster. Certainly, it’s worrisome that someone with his processor design expertise and deep knowledge of IBM research and innovation could end up at Apple, a company that’s made quite a name for itself recognizing the potential of innovations others have left fallow.

Speaking at Microsoft’s (MSFT) Professional Developers Conference in Los Angeles today, Rashid talked up his Apple (AAPL) street cred, reminding attendees that he helped develop Mach, the operating system microkernel that’s now the foundation of Mac OS X. “If you use a Macintosh or an iPhone, which honestly, I would not recommend, you would be using code that I wrote more than 25 years ago,” Rashid said. “If you’d asked me 25 years ago if I thought code I was [writing would be] running today on a cellphone, my reaction would have been, ‘What’s a cellphone?’ It just shows you things really do survive and get used in interesting ways.”

Used in interesting ways in Apple products, anyway. Just ask PARC.
