[email protected] ABSTRACT formative observation study of professional programmers using a Large software projects often require a programmer to make typical development environment to make changes to unfamiliar changes to unfamiliar source code. This paper presents the results code and the usability problems they experience. of a formative observational study of seven professional To combat the expense of software documentation, we also programmers who use a conventional development environment explore cheap ways to transfer knowledge from programmers to update an unfamiliar implementation of a commonly known familiar with the code to those unfamiliar with it. In previous video game. We describe several usability problems they research, Hill, Holland, Wroblewski and McCandless introduced experience, including keeping oriented in the program’s source the idea of computation wear, namely, capturing a user’s text, maintaining the number and layout of open text documents interaction history with a document and making that history and relying heavily on textual search for navigation. To reduce the available to others interacting with the same document [11]. Other cost of transferring knowledge about the program among researchers have developed the idea of collaborative filtering, developers, we propose the idea of wear-based filtering, a namely, allowing users to rate or annotate portions of a large combination of computational wear and social filtering.
