It’s true what they say: You might graduate school, but you never stop learning.

CAR 2011 logoTomorrow is the start of the annual CAR Conference, where “computer-assisted reporters” (affectionately referred to as data nerds, jounocoders, and “those spreadsheet geeks over there”) get together for deep education. As one attendee puts it, it’s where journalists learn and demonstrate how to do things. And that’s pretty great.

I’ll be in town to attend the NewsCamp data visualization workshop, where luminaries like Amanda Cox, Daniel Lathrop and Martin Wattenberg will teach a gamut of dataviz skills. The unofficial attendee list looks pretty spectacular too.

If you’re attending and we haven’t met (or seen each other in a while), say hi. If you can’t make it, Computerworld’s online managing editor Sharon Machlis will be collecting notable info in the window below. You can also follow along via Twitter by searching on “NICAR.”

In case you haven’t heard or seen, Super Bowl XLV TV coverage begins on Fox Sports at 2 p.m ET today, with the kickoff at 6:29 p.m. ET.

Fans, sponsors, and more are pulling out the stops for what’s being described as a classic matchup between two old-school, cheerleader-less football franchises in an unexpectedly icy stadium.

For a sport that has never failed to capture national attention, it’s interesting to see the size of each team’s respective fan nations are in landmass — and to notice how the Green Bay Packers and Pittsburgh Steelers areas are almost evenly matched.

National spectacle knows no bounds, however, and Visa, smartly, is taking advantage with dynamic visualizations of Twitter chatter, including a look at football-related trending topics in the days leading up to today’s big game:

Not everyone will be focused on Super Bowl pre-game coverage, or at least that’s what Animal Planet is counting on.

The Puppy Bowl is back, offering entertainment to those who prefer tumbling fuzzy animals to the charging bulls of the gridiron. Broadcast starts at 3 p.m. ET (tape delayed to 3 p.m. Pacific).

Meanwhile, advertisers have put up big bank to be a part of today’s big game. “Fox was seeking between $2.8 million and $3 million for 30 seconds of time,” writes AdAge, which rounds up facts on all the spots.
