Program The rantings of a lunatic Scientist

A note on Programming vs Software Engineering

L2Program Rant

Oh yes, gather round for another classic Joss rant explanation of common development myths and theories.

Today’s story comes to us from another reddit post, this time asking about why there is (in general) a stigma towards sites like Code Academy who aim to make programming excessible and easy for the masses.


I think a big thing here that just needs to be stated is that Programming is not the same as Software Engineering.

Anyone can go online and learn a programming language, the syntax is relatively easy and sites like Code Academy do a pretty good job of teaching that most of the time. But they teach two things, “syntax” and the very very very basics of “program structuring.”

Developers give sites like Code Academy a bad rep because they actively (if not always intentionally) promote the idea that coding is the same as building a piece of software. They say…

Anyone can do <it>! <It's> easy! Come here today and learn <it>! <It> only takes an hour or two…

<It> being to write lines of code in a text editor and run it, but implied to mean you can start the next facebook.


Software Development is barely connected to coding. The code and the language are just how you write it down and give it to the computer. Yes, there is a lot of coding, sometimes millions of lines of it in a large system. But that pales in comparison to what those lines of code represent.

When you design software you build based on design patterns. Not every pattern is perfect for every situation which is why you need to know a lot of them so you can use the best one for each job. Similarly within those patterns you will be using data structures (arrays, hash tables, linked lists, databases, ect). Again, not one of them works perfectly for every use case. You need to know how they work and which is the best to use for each situation.

Anyone can learn to write int[] a = new int[10]; or HashMap<String, Object> t = new HashMap<>(); in five minutes. It takes a lot longer to learn how they work and when to use them.

That is the difference between “programming” and “software engineering”, and that is why so much of the development community look down on sites like code academy. They paint a false image of the industry and the profession that many of us have devoted many years of our lives and education to.


Now. This is not to say we all know everything and what is best. This is a constantly evolving and changing field and we all are constantly learning and reworking the way we approach the problems presented to us.

I don’t mean to sound discouraging, if I have appeared that way thus far then please have my apologies. That was not my intention. My intent was show why the when the entire world has the ability and accessibility to learn to program and the attitude that they can master web developement and start the next instagram and that it will all be easy because computers are so good these days, that we will still be the same industry we had before they all learned and we will still be the “valued” workforce that we are.

Because you just can’t learn everything we’ve learned by doing tutorials online. Yes we too do online tutorials, watch lecture videos from conferences, go to seminars and master classes.. Yes we do those things too. But we have also been actually doing this work for years, learning from real-life projects, and directly from colleagues who had been doing this far longer than us. Many of us went to university and exclusively studied Computer Science, and algorithms, and software engineering, and project management and lots of other things we use every single day on the job.


In essence, Code Academy and everything it stands for only seeks to invalidate and deprecate everything that gives our experience and our industry value. Even if they did it under the best possible intentions.
