It's not Lego!

While pondering why it is that the state of software development has reached the point that it's at (which very patient long term readers will remember is my usual gripe. Blogger says there are 3 of you! ;) )... where was I?

Right, so anyway, projects seem to be planned very strangely. There are cycles and cycles of proposals, and pre-pre-design documents (though rarely an ACTUAL design document). We have processes designed to break tasks down into a bullet point's worth of work, and we consider that planning. We have code management systems that make actually looking at the code the hardest thing to actually do (I'm looking at YOU, Gitlab...)

And while going through all this in my head and trying to reconcile with the task I'm trying to complete myself, I grumbled to myself "code is hard". And that was the revelation.

Oh, I've always known that it's hard to write good code. Anyone who tells you otherwise is either a liar or a genius, and the odds are heavily stacked in one direction. But I've never had that thought in this context. And that's when it all fell together for me.

Coding is increasingly treated as one of the least important parts of the software development process, maybe second only to testing (which will be a rant one day). And yet coding (and testing) are the only parts of the process that actually matter. They are the only parts that actually produce product at the end of the day.

And so as I was thinking that coding is just brushed off as the least important part of the planning process. It seemed like the assumption was that it was going to be easy to get it right, and testing would be covered by the process. So don't stress that part. And then I realized, there IS a style of development for which this is so, and it's increasingly proposed as the right way to do things.

And that style is: don't do it.

Think about it. You've been on the project that said "can't we just buy a package that does that?" How about "is there a library we can use?"

And so I'm of two minds here. The first one is that, well, yes, re-use is a good thing. Yes, many many many tasks have already been developed in one form or another. And no, I don't desperately want to write a USB stack from scratch. So we can just go out, and take all these pre-written libraries, and write a few lines of glue code, and not only is it likely to work, but it's been mostly pre-tested.(Or, so we blindly assume...) Hell, at this point we're not even the performance bottleneck, so let's just write it in script!

The other mind is the reality that I live in anyway where the exact things we want to do don't exist, and so we're building them. But we still use that building-block mentality. We don't consider that maybe nobody actually knows how to do that, and so it's going to take time to get it right. There is still a world where the hard code isn't written yet.

We've reached a point where many people assume that if something doesn't exist, it's because it's too hard to be possible. Don't you believe it. It only means that someone hasn't done it yet, and nothing more. Get out there. Write the hard code. Get it wrong! Then figure out WHY it was wrong and get it right. Odds are, by that point you'll have created something better than anyone before you did.

Oh, and if you're a project planner, realize that hard tasks take time. ;)
