Text user interface – TUI under Unix-like systems

In Unix-like operating systems, TUIs are often constructed using the terminal control library ”curses”, or ”ncurses”, a mostly compatible library. The advent of the ”curses” library with Berkeley Unix created a portable and stable API for which to write TUIs. The ability to talk to various text terminal types using the same interfaces led to [...]

SCO-Linux controversies – Background

At the beginning of 2003, SCO claimed that there had been “misappropriation of its UNIX System V code into Linux”. However, the company refused to identify the specific segments of code, claiming that it was a secret which they would reveal only to the court. They did say that the code could be found in [...]

Alan Kennedy (psychologist) – Research contribution

Early work on the psychological reality of linguistic rules. Kennedy’s early research (much of it in collaboration with A. L. Wilkes) was concerned with the “psychological reality” of linguistic rules, a preoccupation of cognitive psychologists in the 1970s. This work made use of simple laboratory tasks involving pressing buttons to indicate whether sentence fragments were [...]

Cross-platform – Cross-platform programming

Cross-platform programming is the practice of actively writing software that will work on more than one platform. Approaches to cross-platform programming There are different ways of approaching the problem of writing a cross-platform application program. One such approach is simply to create multiple versions of the same program in different ”source trees”—in other words, the [...]

APL (programming language) – History

The first incarnation of what was later to be the APL programming language was published and formalized in ”A Programming Language”, a book describing a notation invented in 1957 by Kenneth E. Iverson while at Harvard University. Iverson had developed a mathematical notation for manipulating arrays that he taught to his students. In 1960, he [...]

APL (programming language) – Execution

Interpreters Today, most APL language activity takes place under the Microsoft Windows operating system, with some activity under Linux, Unix, and Mac OS. Comparatively little APL activity takes place today on mainframe computers. APLNow (formerly APL2000) offers an advanced APL interpreter which operates under Linux, Unix, and Windows. It supports Windows automation, supports calls to [...]

PL/I – Implementations

IBM PL/I F and D compilers PL/I was first implemented by IBM, at its Hursley Laboratories in the United Kingdom, as part of the development of System/360. The first production PL/I compiler was the PL/I F Compiler for the OS/360 Operating System, built by John Nash’s team at Hursley in the UK: the runtime library [...]

SCO Group – SCO-Linux lawsuits and controversies

FileNet – Open systems

AIX Operating System

In the early 1990′s, FileNet introduced a somewhat “open” version of its WorkFlo Business System software – Series 6500 -that ran on the IBM RS/6000 platform and the AIX operating system. The networking software utilized TCP/IP but used FileNet’s own non-standard encoding for the application protocols. Open protocol standards were not in the FileNet management [...]
