SCO | RIP
Why SCO won’t show the code – At SCO’s annual reseller show, the company’s executives put up a couple of slides as a way of demonstrating how Unix code had been “stolen” and put into Linux. The two slides were photographed and have since appeared on Heise Online; see them here and here. The escape of these slides has allowed the Linux community to do something it has been craving since the beginning of the SCO case: track down the real origins of the code that SCO claims as its own. The results, in this case, came quick and clear. They do not bode well for SCO. More Abstract This paper reports on the design rationale and formative evaluation of an intelligent tool to aid intermediate and advanced student programmers, who already have knowledge of another programming language, in acquiring a working knowledge of key parts of the Ada programming language. Research on transfer between programming languages has shown that, while previous programming experience helps students to learn subsequent languages, it also can be a source of negative transfer. In particular, students have little trouble with the syntax of the new language, but they do have difficulty in planning a solution which takes advantage of the features of the new language. Our tool, ADAPT, applies existing artificial intelligence technologies to the pedagogical problem of transfer between programming languages, with emphasis on the problem of developing programming plans which are appropriate to Ada. ADAPT was designed based on the findings of research in the cognition of programming. A prototype of the tool was developed, and a formative evaluation was carried out to evaluate the cognitively-based design decisions guiding ADAPT.
