If, after four days of Code4LIB, you are not yet conferenced-out and are staying in Raleigh for an additional day, why not attend THATCamp Digital Knowledge at the James B. Hunt Jr. Library on March 28 from 10 to 5 and also help us celebrate Arduino Day? Attendance is free, you just have to register (see the announcement below). ++++++++++++++++++ THATCamp is an opportunity for faculty, grad students, university staff and members of the public to learn and play at the intersections of technology, humanities, social sciences, arts, and libraries. Participants are welcomed to propose sessions that relate to digital scholarship and pedagogy or any other topic they'd like to explore with fellow attendees. Sessions typically enable participants to develop new skill sets, think through ideas in a cooperative setting, and workshop current and future projects. (See the instructions on what sorts of sessions you might propose in advance or on the spot.) This year, THATCamp also invites attendees to use the Hunt Library's high-tech spaces including the Teaching and Visualization Lab, the Game Lab, and the Creativity Studio. Staff will be on hand to assist with running and configuring these spaces. In addition to sessions that participants propose in advance or on the spot, THATCamp will offer hands-on workshops led by librarians and faculty on the Arduino microprocessor, as part of NC State's parallel celebration of the worldwide Arduino Day 2014. Other sessions will focus on topics and technologies ranging from Google Glass to data visualization and GIS to multiplayer interactive fiction. Please note: participation is limited to 75 people. To attend, please register by March 26.
