Ask Slashdot: What Do You Wish You'd Known Starting Out As a Programmer?
snydeq writes: Most of us gave little thought to the "career" aspect of programming when starting out, but here we are, battle-hardened by hard-learned lessons, slouching our way through decades at the console, wishing perhaps that we had recognized the long road ahead when we started. What advice might we give to our younger self, or to younger selves coming to programming just now? Andrew C. Oliver offers several insights he gave little thought to when first coding: "Back then, I simply loved to code and could have cared less about my 'career' or about playing well with others. I could have saved myself a ton of trouble if I'd just followed a few simple practices." What are yours?
What Do You Wish You'd Known Starting Out As a Programmer?
How to program, I guess.

I wish I had known to pick a different trade instead of programming. Programming isn't a profession like law or medicine. It's a skilled trade like plumbing, masonry, or electrical work. But unlike plumbers and electricians, programmers aren't smart enough to unionize, and so they get fucked in the ass by management. If you have to live in the United States, don't become a programmer. There are better ways to earn a living.

I would have studied more about the history of computers and computer science. It would have kept me from re-making so many mistakes and re-inventing so many wheels.

I like you, Stuart. You're not like everyone else, here, at Slashdot.
I wish I had known how uninteresting and boring coding could be when working for a corporation. It was the ability to be creative and imaginative that made me fall in love with coding in the early eighties. Although I still work in IT, I generally don't code for companies anymore. And somehow coding has miraculously become very interesting once again!
Political correctness is really just herd psychology pushed by insecure people who desperately seek social conformity.
Though I inevitably unconsciously think about work code during non-work time, I will never consciously spend time thinking about or working on work code during non-work time.
They are paying for my brain, they can pay me to sit and think for a while. The actual typing of code is not what programming is.
Going by my wife's experience, I can suggest a better way to discourage somebody from learning to code. It's called Java.

This Programmer Competency Matrix has been instrumental in helping me "know what I don't know".
I just had my one year anniversary as a full time Android developer, and it's insane how much I've learned after leaving school. Luckily there's two older guys (well, one now, the other moved on recently) on my team who are _awesome_ mentors.
1. Pay attention to everything you can in the work place. You may be a client side developer, backend, whatever, but pay attention in every meeting or conversation that you can eavesdrop on. You may not understand everything going on with the teams you don't work in, but just being exposed to their terminology and _looking up what they're talking about_ will get you far. This doesn't go for just development, either - listen to the business and sales guys talk and try to understand your clients and what they need so you can build a great product by anticipating what will work for them before they have to ask.
2. Write a blog. Seriously. I'm the first to admit that I don't really know anything when it comes to development, but I've been actively writing new posts to my blog and it forces me to grok whatever I'm writing about. Whatever you're doing, post the code on GitHub so others can read it (mine's here). Developers who read peoples code online tend to be awesome about making suggestions and asking questions that make you realize you screwed up without being jackasses about it.
3. If there are tech meetups in your area, go to them. If you're in a decent sized city (I'm in the Denver/Boulder area, which isn't huge, but it's a lot bigger than where I'm originally from) you can find multiple meetup groups related to tech that you're interested in. It's a great way to learn new things and meet a lot of awesome people in your area.
4. If there's hackathons in your area, no matter how small, go to them. You meet awesome people and learn how to work in teams that are different than the one you're in every other day. Plus there's usually free food and beer, so what's not to like about that?
5. Pick up skills that compliment your work area by doing projects that aren't work related. It helps you understand what other teams are doing and how it affects you, plus it just makes you more awesome while keeping down the monotony. As a client side developer, I've been taking a Udacity course on using AppEngine to make backend APIs, and it's been fun.
6. For the love of God, check for null pointers and other kinds of exceptions. You may not catch all of them due to inexperience in spotting them, but that's what senior devs doing code reviews are for. You don't want code going into the wild that crashes, even when data is bad. Getting a call on a Saturday saying something bad is happening is not what you want - the weekends are yours to do whatever you want, not put out fires that could have been avoided.
7. Open source third party libraries are your friend. People way smarter than me have put together some amazing things that we use every day, like Otto and Picasso from Square. Try libraries out in a sample project, and if they will work for what you're doing, give it a shot. If you can make them better in the process, submit a pull request. Like I mentioned earlier, the open source community is awesome and if your pull request isn't up to par, they'll let you know what you can do to fix it.
8. You're going to fail at some things, and it's alright. Fail early, learn what did and didn't work, and try again. Learning from mistakes is how you get better. Along this same line of thought, if you run into a roadblock that you can't figure out yourself via documentation/stepping back and evaluating the problem, StackOverflow is awesome.
Here's my advice, been programming for 15 years. Write comments, one per block of code that does a step, then fill in code. You will then have well commented code, and forced yourself to think through the solution before you begin coding. This saves tons of time by avoiding thought errors before you code. When hunting a bug, don't just look at what's not working. Instead look at what was most recently changed, even if it seems it couldn't possibly be related. The times I didn't do it this way have cost me many days hunting down a really tricky bug. Sometimes it really is unrelated to recent changes, but not often. If you are stuck, take a break and do something mindless, like get some water, go to bathroom etc. your subconscious keeps working without the interference of your conscious mind. Preplan your work a few days ahead if possible. You can avoid many roadblocks by thinking through things ahead of time. Persistence pays off. I've worked through many "seemingly impossible" tasks, only to find the solution after failing a few times first. Visualize what the users interaction will be before coding. I like to draw it on paper and pretend to use it. Putting yourself in your users shoes allows you to see what might be difficult to understand. I rarely keep my first design, but since it's just a drawing I'm not invested in it. If you lay it out in software, it's much more tempting to keep a poor design. Ask a colleague if you are stuck. Often, articulating the problem out loud is sufficient to solve it!
I wish I had learned to balance real life with coding life sooner. I used to do the same zillion hour marathons everyone else did at one point or another in their coding careers. I loved the challenge and being the one producing the results. But then, eventually, I realized there's really a LOT more out there than that tiny little challenge/reward cycle. Biking, hiking, sports with friends, whatever. You can easily burn through 10-15 years of your YOUNG life living the code only to realize later when you're not so young any more that there were TONS of things you would have enjoyed doing more. You can make up some of that, but not nearly all.
I'm going to answer this in a different way: what I knew when I started that I think most programmers, and most people, don't. That may sound arrogant, but I keep seeing it every day of my working life.
I wasn't a computer science major or anywhere close: I was a film major and English minor. It was the English that has helped me more than anything learn very quickly certain secrets to programming effectively. And yet it wasn't even the English classes themselves, because a lot of what is fashionable to teach in English is misleading or harmful.
What really happened was a certain approach to writing. It is taught clearly in just a few books, like The Elements of Style and On Writing Well. Reading these books literally changed my life. If I were to try to summarize it, it would be that the goal of writing is to reach the reader as plainly as possible, instead of writing in a flowery, fancy, or important-sounding way. To do that actually is the greatest amount of work. It actually is the opposite of everyone's inclination. Even for professional, longtime writers, it doesn't happen on the first draft or even the seventh draft. It involves adhering to certain non-glamorous principles like using as few words as possible and preferring the short word over the long one. It means putting yourself in the background. In short, in trying to be elegant.
