Python-32 years old

DO YOU KNOW ??? Python Language is 32 years old On February 20, 1991, Dutch programmer Guido van Rossum released the first version of a project he had been tinkering with since Christmas break two years prior: A brand new scripting language, called Python. Back then, there was no telling how popular Python would become and the impact the language would have on the world of coding. Even van Rossum, who went on to work at Google, Dropbox, and Microsoft, didn’t see the hype coming. “When I originally started Python, I didn’t expect there would be great success and fame in my future,” van Rossum said on an episode of the Lex Fridman Podcast.  In the 32 years since Python launched, the language has become a go-to for millions of developers, from beginners taking their first foray into coding to experienced engineers who use Python for machine learning and AI. In fact, Python is the most popular programming language in our course catalog .   If you’ve n...

UNIX-FIRST OS

DO YOU KNOW??? Unix was one of the first opearating system kernels implemented in a non assembly language and that was c.   Prior to 1973, Unix was written in assembler language, but the fourth edition was rewritten in C. This was revolutionary at the time because OSes were thought to be too complex and sophisticated to be written in C, a high-level language. This increased Unix's portability across multiple computing platforms. In the late 1970s and early '80s, Unix amassed a strong following in academia, which   led commercial startups, such as Solaris Technologies and Sequent, to adopt it on a larger scale. Between 1977 and 1995, the Computer Systems Research Group at the University of California, Berkeley developed Berkeley Software Distribution (BSD), one of the earliest Unix distributions and the foundation for several other Unix spinoffs. In 1991, Linus Torvalds, a student at the University of Helsinki, created a Unix-based OS for his PC. He would later call h...

NINETY-NINETY RULE(90/10) LAW.

Do you know??? The 90/10 law states that 90% of a computer program's execution time is spent executing 10% the code. In   computer programming   and   software engineering , the   ninety-ninety rule   is a humorous   aphorism   that states: * The first 90 percent of the code accounts for the first 90 percent of the development time. The remaining 10 percent of the code accounts for the other 90 percent of the development time.-   Tom Cargill, Bell Labs This adds up to 180%, making a wry allusion to the notoriety of software development projects significantly over-running their schedules. The anecdote expresses both the rough allocation of time to easy and hard portions of a programming undertaking, and the cause of the lateness of many projects in their failure to anticipate their difficult, often unpredictable, complexities. In short, it often takes both more time and more coding than expected to complete a project. The rule is attributed to Tom...
