Dbxtool is a window‐ and mouse‐based debugger for C, Pascal and FORTRAN programs running on Sun workstations. Its use of the mouse as the primary input mechanism eliminates the need to type variables, line numbers, breakpoints and most commands. Its multiple windows provide several qualitatively different perspectives on the debugging problem. Compared to the Unix 4.2 BSD dbx from which it is derived, it has been extended with the abilities to debug multiple‐process programs, already‐running processes, and the Sun Operating System kernel.
The Sun Network Software Environment ("SE) is a network-based object manager for software development. The NSE supports parallel development through an optimistic concurrency control mechanism, in which developers do not acquire locks before modifying objects. Instead, developers copy objects, modify the copies, and merge the modified objects with the originals. Objects managed by the NSE are typed, and the set of types can be extended by tool builders. The NSE is designed to work with heterogeneous implementations and poor communication.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
