Boston’s new District Hall is many things: event space, coffee shop, meeting room, restaurant. Add one more to the list: dojo.

No, Mr. Miyagi is not coming to South Boston. But the city’s young grasshoppers will have a chance on Nov. 23 to learn what you might call digital karate: web and mobile development, computer programming, and game design.

The one-day session will be led by a nonprofit called CoderDojo, which runs youth computer clubs in 27 countries, and will be sponsored by Waltham venture capital firm Polaris Partners. It’s free for kids between the ages of 10 and 14, and you can sign up here.

“We are thrilled that Polaris will help bring coding to Boston kids,” Boston Mayor Thomas M. Menino said in a statement. “What could be better to bring together at District Hall than students and their potential?”

The sensei at District Hall will be CoderDojo founder James Whelton, a teacher who started the organization two years ago with a single computer club at his school in Cork, Ireland. Whelton launched the Hello World Foundation this year to support CoderDojo’s growing network of computer clubs, and Polaris has signed on as the foundation’s first corporate sponsor.

“For years, we have been committed to supporting the technology community in meaningful ways, and CoderDojo is an investment in our collective future,” Polaris managing partner Dave Barrett said in a statement. “Imagine the entrepreneurial power of a new generation that can thrive technologically in the same manner that our generation did in areas such as athletics and the arts. We are supporting something very special here.”
