A Look Back: software Development Then and Now – And Why C Still Matters
The world of software development has changed dramatically in the last few decades, yet some core principles remain surprisingly consistent. Reflecting on the “early days” – before ubiquitous internet access,rapid iteration,and sophisticated tooling – offers valuable outlook for any modern engineer.Let’s explore how far we’ve come, and why understanding the foundations, like the C programming language, is still incredibly relevant today.

These weren’t simply manuals, but inspiring guides showcasing the potential of C. Imagine an eager software engineer, armed with this knowledge, exploring the possibilities of this relatively new language! Similar to learning assembly language – where the syntax is minimal but creative power is immense – C offered a direct connection to the machine.
The Pre-Git Era: Managing Code Without Modern Tools
What about version control? Git, a cornerstone of modern development, didn’t appear until 2005. Back then, software version control was a decidedly manual process.
Consider these common practices:
* Developers often maintained their own local source code management systems.
* Some teams even used wall charts to assign “ownership” of specific source code files. (you can read more about this fascinating practice here).
* Sharing code involved physically handing out floppy disks to colleagues.
Iteration cycles were considerably slower. Software releases primarily occurred on physical media, and over-the-air updates were rare. Consequently, gathering user feedback wasn’t the rapid, iterative process we experience today.
Why You Should still Explore C
If you’ve never worked with C, consider giving it a try. Drop that MicroPython implementation on your ESP32 and explore the power of C. It will require an initial investment of time, but the benefits are ample.
Many modern languages draw inspiration from C,so the concepts will feel familiar. Just be mindful of manual memory management – that’s where the potential for “garbage” arises.
A Surprisingly Consistent Core
Interestingly, the essential structure of code hasn’t changed that much. Take a look at the classic “hello, World!” program in C:
#include <stdio.h>
int main() {
printf("Hello, World!n");
return 0;
}you’ll find striking similarities to the earliest FORTRAN programs. The core logic remains remarkably consistent.
The Acceleration of change
The pace of change in software development will only accelerate in the coming decades. From Object-Oriented Programming to the rise of the web, from Java Virtual Machines (JVMs) to Large Language Models (LLMs), the evolution continues.
This is just the beginning.
What’s Next?
I’ll be diving deeper into these trends in PART 2 of this blog series, which I’ll be posting in the next few weeks on the AWS Builder Center. Please follow me there to stay updated!
See you soon!
