Things I don’t know as of 2018

At the end of last year, Dan Abramov talked about the things he doesn’t know. It’s a useful framework to reflect, and as a privileged, experienced developer, I am comfortable talking about this, in the hope it might help others understand that experienced developers don’t know everything.

I’ll echo what he says about Imposter Syndrome and Dunning-Kruger and how it absolutely sucks to see truly smart developers I know, or that I follow, having to constantly prove their credentials just because they’re not cis, straight, able-bodied white men. If I’m in a position to support you or amplify you, I will try to do so. Your experience is definitely a thing I don’t know, but I can listen.

I covered a few things I know enough to be confident in for my 2018 in Review post. I’ve had to care about DevOps and containers and pipelines because they solved real problems my team was having. I love graphics because trigonometry and fractals are why I got into programming, but I work in the network, looking at architecture, security, interfaces and data. That leaves a big wide world out there, and this doesn’t include the unknown unknowns.

Ruby

I’ve tried to get into it a few times, but it still just looks like old-school Perl to me. Lots of punctuation occasionally interrupted by domain language. This actually sounds like a good idea to me – an almost complete separation of concerns – but I keep finding the learning curve too steep and so I retreat back to Python and C#.

CSS

I’ve been building websites since Mosaic was a browser. I can style things with CSS. It’s not hard to put red text on a green background (you monster), or fix a navigation bar to the top of the screen, but look at the fancy grid layouts, or parallax scrolling effects, or CSS icons, and I couldn’t tell you where to start. I don’t know how to unit test it, so my tools don’t work here. Just as well I work with some very smart CSS developers.

Markdown

I use Markdown a lot. For README, for Architecture Decisions, and for drafting blog posts, but I always need to google how to insert a link, or a table, or an image. And I feel like an idiot each time.

gulp, npm and webpack

I know these are essential tools when I’m building React. I know they turn my code into something the the browser runs. I know how dependency management works (I can bore you about HORN over a drink if you like), but I’ve only ever used these JavaScript tools preconfigured in a template or an existing codebase, so I could not create a JS or TypeScript build pipeline from scratch, or fix a broken one.

I really couldn’t tell you anything intelligent about how those fit into the ecosystem alongside Grunt, Yarn, bower, sass, scss or anything else. So long as I can write a script to install and run them, I’m happy not to have to dig into them. All I care about is if it runs and if the dependencies are secure.

I suspect I’ll need to learn more about these tools this year though.

You don’t need to know everything

You’ll have your resolutions to learn more, whether weekly or yearly. There’s more to learn than you will ever get the time to – that’s why we work in terms. Pick one thing to learn next because it’s important to you, because it’s interesting, because your project requires it, or because thats where the money is. Forget the rest until you’re over the Dunning-Kruger curve and you know enough about that new thing to see all the possible next things to learn.
