As the number of source files and libraries required to build a software increase in number, the build process gets more complicated and the time required to build the final executable becomes more and more. Here, the classic make utility available in Linux and other Unix-like environments comes to the rescue as it automatically builds the software based on rules given in a makefile and optimizes on the build process by compiling only the files that have changed since the last build.… Read more

The major activities required in a software development life cycle (SDLC) were identified in the waterfall model. The agile concurrent software process model proposes that the activities identified in the waterfall model are not done sequentially; these activities progress concurrently with varying intensities during the entire software life cycle.
More software projects have gone awry for lack of calendar time than for all other causes combined.
Work happens slowly. Why get impatient? No matter how much you water the trees, the fruits will come only at the right time.… Read more

THE EARLY DAYS
Compatible Time-Sharing System, CTSS, was developed at MIT under Project MAC. It was one of the first time-sharing operating systems, demonstrated in 1961 and was in use till 1973. CTSS was used on IBM 7094 and was "compatible" with standard batch processing OS for 7094, the Fortran Monitoring System (FMS); it ran a copy of FMS in background.… Read more
