Why Do Command Lines Still Exist ?

GUI (graphical user interface) is easy to use and goodlooking. But CLI (command line interface) is faster and easier to automate. Advantages of Command Line over Graphics Graphics are fancy but lack clarity and prone to errors and crashes and uses alot of resources (RAM, CPU and GPU). Here are some advantages. Lightweight Text Interface If you accomplish a task like converting mp4 to mp3 on command line using ffmpeg, it will be faster than using any other GUI program such as Format Factory (for Windows OS).

Why built-in functions in python are faster ?

Because Python is sitting of the shoulders of giants. Built-in functions are written in C and C++ under the hood. C and C++ languages are efficient and fast, so their functions will be faster than the functions you write in Python. So it is recommended to use built-in functions instead of creating new ones.

Why Do People Use Go ?

People use Go programming language For various reasons. Here is all reasons in brief: Go is open-source but backed up by a large corporation (Google) It’s fast: to learn to build up to compile to arrange and install to scamper Go is a modern language Go is Simple It is Concurrent Static code analysis Garbage collected language

Why is n++ faster than n=n+1?

The answer is related to the old CISC cpu instructions and the way how C (or any programming language) is compiled to binary code. In almost every CISC CPU there is a special “add” instruction that is named INC (or DEC) and that instruction increments (or decrements) by 1 the value of a register (or memory). If you use another instruction for addition you have to add both operands you want to sum.

Why Did Google Develop Go ?

Google has two tremendous problems. One of them is compile time. Back in the 1980’s, reasonable sized projects took hours to do a clean build. There were whole server farms dedicated to recompiling. You got a new “nightly build” and made modifications to that. Google builds things that are so ridiculously huge that it’s still like that in 2017. It takes 5 hours to rebuild chrome from scratch even on a big fat i7 system.
