CS != Programming...
Initially, learning CS appears to be like learning many seemingly unrelated subjects together. But with maturity and experience, you will be able to understand that these subjects are all connected.
C++, Java, Python - you name any object-oriented language - they seem to be different, but only to those who don't deep dive. Once you master the fundamental object-oriented part of these languages, you will realize that they are all the same.
Design patterns help you get to the core of any object-oriented language. Once you master the Design Pattern, you will never say how to write this program, but how this program should be designed to hold the basic object-oriented principles and how it will interact with the outside world. So you will never say that we will pick up the correct implementation of a system during runtime. Rather, you will exclaim - can't we use Strategy Design Pattern here?
However, we must understand that software or computer science is not that useful unless we apply it to real-life engineering problems. There lies the satisfaction of a scientist and an able engineer. At this juncture, the true maturity of a Computer Science guy is judged.
Many ecosystems split engineering work across tools:
MATLAB for modeling
Python for data
C++ for performance
Simulink for block diagrams
Julia collapses these layers.
You can:
Write high-level control logic
Drop to numerical linear algebra
Move into differential equation solvers
Even implement custom integrators
All in one language.
For so many years, the process of engineering computer science was that the scientists modeled an engineering solution, and then software engineers would realize it through code. But what if we want the scientists themselves model and write code to execute that model - all by themselves? For that to happen, we needed to develop a language with a deep binding with the engineering Maths and Physics.
Enter the world of Julia - and you got it - model any scientific problem and then produce the code all alone - the beauty of julia.
As my journey to know WhoAmI continues, my respect for the julia programming language is increasing day by day. So when I can model a PID control or a dipole antenna in Julia, the joy is natural.
I never thought I would be able to delve into hardcore engineering subjects after so many years of engineering graduation.
But this is the reality.
My exploration continues.
Below is the output of a PID control developed using julia.
And here's the far-field radiation pattern of a dipole antenna...
The greatest job satisfaction is always to be at the juncture of software and engineering.
And I am loving it.
