“Coding”, to misquote Douglas Adams, “is hard. Really hard. You just won’t believe how vastly, hugely, mindbogglingly hard it is. I mean, you may think it’s difficult to walk down the road to the chemist’s, but that’s just peanuts to code, listen…”
Except it’s not. Not really. And that bit about the chemist’s makes no sense. Thanks for nothing, Simon.
Writing a little bit of code is easy. So easy, that I’ll do some now. Here:
<b>Make this bold</b>
See, that wasn’t so hard, was it? That’s one line of HTML. HTML is what’s called “markup”, code for styling text on a website. The angled brackets indicate that what is within them is a command. This command is sent to the “code interpreter”, which reads the code and turns it into:
Make this bold
At the end, there is another set of angular brackets, with a forward slash to indicate that you can stop making it bold now, thank you very much. So to the compiler, it reads:
Start making the next bit bold until I tell you to stop
This is the specific text that I want you to print out, so just print it out
Stop making it bold now
That’s quite straightforward, but using essentially that principle (and a few others), you can start building most websites in the world. And end up with code that looks like this:
A little bit of code is easy. A lot of code is hard.
The way computers “think” is just very different to humans. Densely written text like that is almost impossible for a human to read. But for computers, this isn’t a problem. They just start at the beginning, and work their way through. Very quickly. In milliseconds. It would take us humans with our monkey brains much, much longer to go through it all.
The upshot of this is that once you go beyond writing a couple of simple lines of code, managing the code becomes a bigger job that actually writing the damn stuff. And when you throw some other coders into the mix, with their own way of coding, and their own idea of how code should be indented (it’s tabs, for Christ’s sake, not spaces!), you start to see why coding is so hard, and why so many software projects fail.
In this blog, I’m going to take a walk through coding, development and software. Looking at what goes right (and wrong), why coding is the way it is, and talk about some of the concepts involved in coding and development. You won’t learn anything useful from this site (it’s not Coding for Dummies or anything like that). But you will learn lots of useless things. And, if I’m honest, I’ve always preferred useless information anyway.
