Celestina Perea, left, and Nora Cullinan work with Neale Pickett at Queen of the Hill 2017, a coding workshop for girls in grades 7-11, held Saturday at UNM-Los Alamos. The 17 attendees split into four teams and competed for points in codebreaking, steganography, sequence prediction, and base arithmetic. Later the girls focused on individual interests. For example, one participant focused on the fundamentals of cryptography, while another attendee worked with graduate students to delve into network protocol analysis.
