Almost 20 years ago, in 1987, seven women met at SOSP (Symposium on Operating Systems Principles). As the only women at the conference they all felt like outsiders, so they banded together to be less isolated. At a dinner meeting, they discovered that they had many experiences in common. Anita Borg, one of those original seven, offered to host a mailing list for the group to continue their interactions. The name chosen for the group was “systers,” a wordplay on sisters and systems. As the systers list approaches its twentieth anniversary, it seems timely to reflect on its history and its current goals.

Last spring, three of my women friends compared life stories at our 20th college reunion. They had all chosen the academic path in mathematics and computer science. While seemingly successful, it turned out that each felt unsatisfied to some degree. The first had left her tenured position because she hated the atmosphere; a tenured position at another university requires a move, so she has settled for being an independent researcher and consultant. The second had an exhausting commute; she was pessimistically contemplating her options in finding work closer to home. The third was happy in her job at a prestigious department, but she had yet to get tenure; and, as the tenure-track rat race took precedence over her biological clock, she was still childless in her early forties.

My morning routine is to stop in the office early and see what has come in during the night. Then, over yogurt, cranberry juice, and The New York Times, I let issues sift and settle. Afterwards I reverse my commute—all thirty-four steps of it—and return to my study. I am a Distinguished Engineer at Sun Microsystems and I work from home.

Gender differences in computer science tend to dissolve—that is, the spectrum of interests, motivation, and personality types of men and of women becomes more alike than different—as the computing environment becomes more balanced. This finding is emerging from our ongoing studies of the evolving culture of computing at Carnegie Mellon as our undergraduate computer science (CS) environment becomes more balanced in three critical domains: gender, the mix of students and breadth of their interests, and the professional experiences afforded all students.
