What are the laws of programming?

Any given program, when running, is obsolete. The value of a program is proportional to the weight of its output. Program complexity grows until it exceeds the capability of the programmer to maintain it.

What is the first law of software design and why is it important?

Lowering quality lengthens development time. Quality software takes the least amount of time to develop. If you have code that is simple as possible, tests that are complete and a design that fits just right, additions and changes happen in the fastest possible way because the impact is lowest.

What are the principle of a good programming?

SOLID principle supports good object-oriented design and programming. Five of these principles are described as SOLID: Single responsibility, Open-closed, Liskov substitution, Interface segregation, and Dependency inversion.

What was the first law specific to computer software?

The United States of America was the first country to enact specific legislation directed towards copyright protection in the form of the Computer Software Copyright Act of 1980.

What are your 10 Laws of programming?

The ten rules are:

  • Avoid complex flow constructs, such as goto and recursion.
  • All loops must have fixed bounds.
  • Avoid heap memory allocation.
  • Restrict functions to a single printed page.
  • Use a minimum of two runtime assertions per function.
  • Restrict the scope of data to the smallest possible.

What is the second law of software engineering?

A work on software engineering by Ivar Jacobson et al, in 1992 describes software entropy as follows: The second law of thermodynamics, in principle, states that a closed system’s disorder cannot be reduced, it can only remain unchanged or increase. A measure of this disorder is entropy.

What is the second law of software engineering and design?

This leads us to our second law of software design: Your software is going to change. It’s not going to change by itself, but unless you just give up and decide you don’t want people to use your software anymore, you as a programmer are going to have to accommodate the demands of a changing environment.

What are the 3 control structures in programming?

There are 3 main control structures in programming: Sequence, Selection and Repetition.

Is Moore’s law?

Moore’s Law refers to Gordon Moore’s perception that the number of transistors on a microchip doubles every two years, though the cost of computers is halved. Moore’s Law states that we can expect the speed and capability of our computers to increase every couple of years, and we will pay less for them.

What is entropy in programming?

In computing, entropy is the randomness collected by an operating system or application for use in cryptography or other uses that require random data.
