There are two types of programmer in the world.
Now when somebody writes that on their blog, they’re generally criticised as being elitist and condescending. This is because they tend to talk about the “alpha geeks” or the “20%,” and everyone else or the “80%.”
I’m not going to say that. But I am still going to say that there are two types of programmer.
- Those for whom programming is a means to an end.
- Those for whom programming is an end in itself.
If you’ve been following me on Twitter, and if you’ve read my recent blog posts, you’ll know that this has been something of a theme for me for the past couple of months or so. What got me going about it was reading this remark in a blog post by Jeremy Miller a few months back:
I had a great time at CodeMash yet again. For those of us who look at software development as more of a lifestyle than just a way to meet the mortgage, these kinds of events are like a huge dose of nutrition for the soul. I really liked Scott Chacon’s keynote address and it’s got my head a going about how to make our workplace better (see this again).
It’s not a bad post, all in all, but whoa there. Since when was software development supposed to be a lifestyle?
Don’t get me wrong here. I’m all for being passionate about programming, for sharpening the saw, for improving your skillset, for using the best tools for the job, and all that, but when I hear of people describing software development as a lifestyle, I wonder just what makes them tick. And this isn’t a criticism of Jeremy either. It’s more a criticism of myself. There have been times when I myself have slipped into that way of thinking, and I’ve not found it to be beneficial. It’s easy to fall into that trap when you have the kind of mind that enjoys programming, and it takes a good deal of self-discipline to avoid it. In fact, paradoxically, I find that when I get into programming-as-an-end-in-itself mode, I end up getting less code written, not more.
This, in a nutshell, is what’s been behind a lot of the things I’ve been blogging about recently. It’s been behind my recent decision to stop using vim, for instance. For that, and everything else I’ve been looking into, I’ve been asking myself the question: is this a means to an end, or is it an end in itself?
So to those of you who would want to persuade me to reconsider learning vim properly, or to switch from Mercurial to git, please allow me to remind you of one important fact.
You can’t learn everything.
As programmers, we face a firehose of new tools, new technologies, and so on. Many of these are promoted loudly with great fanfare on the Internet by their fans. In the case of some (*cough* git *cough* ruby on rails *cough*) the fanboy hype is deafening. Most of them are claimed by their proponents to be counterexamples to Fred Brooks’ classic essay, No Silver Bullet. Almost none of them are anything of the sort. Yes, they are beneficial to a greater or lesser extent, but in most cases, there are trade-offs.
It simply isn’t possible to give all of them more than a cursory once-over. You have to triage what to learn and what not to learn. Aggressively. Learning vim would rob me of time familiarising myself with other, more important technologies such as Selenium or backbone.js, for instance. Frameworks and tools that you do learn are huge and complex these days, and if you try to learn too many of them, you end up with a very superficial understanding of them that can lead to problems. Either that, or else you end up spending so much time on the computer that you damage your health and your relationships with other people.
So in the past few weeks, I’ve been taking a good hard look at everything I’m doing, re-evaluating what I should be taking up, what I should be dropping, and what I should just allow to carry on as-is. With that in mind, I’ve been formulating some criteria by which I should decide what to adopt, and what to ignore. With everything I’ve been doing, I’m asking myself a few pertinent questions now:
- Does this solve a problem that I am currently facing or am likely to face in the not too distant future? If so, how effectively?
- Will knowing it enhance my career prospects? More importantly, will not knowing it harm my career prospects?
- Are there any examples of real-world applications using it, or is it all smoke and mirrors?
- What is the ramp-up time, and is it worth it?
- Is it in line with the direction I am heading, or is it a distraction?
- If it makes programming easier, does it do so at the expense of the end users?
The last point is a key implication of programming being a means to an end rather than an end in itself. If programming is a means to an end, and you care about your end users, you will base your choice of tools and frameworks on what serves them best. On the other hand, if programming is an end in itself, you will choose the cool languages and tools that everyone is raving about, but at the expense of your audience. This is of course what WordPress got right but Diaspora got wrong.
The ALT.NET movement makes me feel a little bit uneasy somehow. While there are some pretty good people in there, and I fully support the aim of finding better ways to do things, the movement as a whole seems to have largely degenerated into a clique of programming-as-an-end-in-itself Ruby fanboys with inflated egos who only do .NET under protest for their day jobs, and who complain about Microsoft tools purely for the sake of complaining about Microsoft tools. I ended up in conversation on Twitter with several of them in the wake of my TFS==Lotus Notes blog post, and I think some of that may have rubbed off onto me. Certainly, I’ve been doing far too much complaining recently, and I’m sure it doesn’t make me look good.
I’ve come to the conclusion that the programmers most worth following on Twitter, most worth subscribing to in Google Reader, are the people who are building end-user applications aimed at non-developers. This isn’t necessarily because they’re smarter — frameworks and developer tools are technically more challenging beasts to write and maintain — but because they tend to have a better grip on reality. Building end-user applications puts activities such as socialising and speaking to non-programmers right at the heart of programming: you have to talk to people before you start in order to get ideas, and then you have to talk to them afterwards in order to make sure you’ve delivered something that they can use without getting confused. And of course, you also have to talk to them in between times to make sure you are on the right lines. This is where agile software development hits the nail on the head — developers are expected to talk to the customers on a daily basis. On the other hand, only ever building programming tools and libraries, and little or nothing else, seems a bit self-serving to me.
At the same time, I’ve also been asking the same questions about my blog. Over the past few years, I’ve constantly found it to be a very time consuming animal, where I don’t see much benefit coming out of it, and I keep wondering why I do it. Most of my recent blog posts have said, “You should be doing this,” or “You shouldn’t be doing that,” or “This is a cool tool,” or “That process is bad,” or other things in that vein, and I’ve been saying very little about what I’ve actually been doing myself. This is just punditry, and I don’t want to be just another talking head. We have too many talking heads in our industry, and it gets rather boring after a while.
I also think I got carried away somewhat with the whole Mercurial/source control thing. Now don’t get me wrong: I still maintain that Mercurial is the best source control tool available today by a long shot, that only git comes anywhere near it, that the old-school centralised model is past its sell-by date and no longer fit for purpose, and that if you’re not using a DVCS, you’re harming your productivity, making a rod for your back, and exposing your project to unnecessary and unacceptable risks. But there comes a time when you have to let things drop, otherwise you end up coming across like a noisy fanboy yourself and you just annoy people who have missed them as they flew straight past coming out of the firehose. In fact, this fanboy attitude is totally out of order in the Mercurial culture itself, where viewing programming (and by extension, source control) as a means to an end and not an end in itself is very much the norm.
I’ve therefore decided that I need to take a break from blogging for the next few months. Quite when, or even whether, I return is anyone’s guess, but if I do, I’m not planning to carry on writing in the same vein as I’ve been doing so up to now. If I’m to carry on blogging, I want to build stuff that I can talk about and showcase here on my blog first. Unfortunately, at the moment, most of the code I write that’s worth talking about is at work, and there’s obviously a limit to how much I can write about that. But the Agile Manifesto tells us to favour working software over comprehensive documentation, and as a corollary, the contents of your github or bitbucket account say more about you as a developer than the contents of your blog.
I’ll no doubt continue working on some personal programming projects in my spare time. In fact, hopefully I’ll be able to spend more time working on programming projects without getting distracted by blogging about x, y or z. But it will have to be time-boxed anyway. During the week, I am out of the house from seven in the morning until seven in the evening, which doesn’t leave me much time for anything other than sleep, and I want to free up more time for socialising, church activities, and developing other interests that don’t involve sitting over a computer.
