Comment: Avoid over engineering and over generalising (Score 3, Insightful) 394

by rgravina (#34471978) Attached to: Programming Mistakes To Avoid

The biggest programming mistakes I've had the displeasure of making, or discovering in others code, almost always centre around one of these two problems:

1. The code is over-engineered
2. The code was abstracted before there was even a need for the abstraction.

I remember when I was less experienced, how thrilled I'd be over code that was clever, solved many problems aside from the one I was trying to solve, and had some clear reusability built in. What a work of art, I thought.... until I eventually realised that much of the extra code I had written didn't get used, the abstracted code was never reused - or even if it was, I couldn't predict how it would be reused and the abstraction was clumsy at best, useless at worst.

It's sad when this happens - good intentions, but the end result is a lot of waste. I'm embarrassed to look over my earlier code which is like this.. I like to think I do it less now, but the temptation is always there... I'm going to need to do this later anyway... I can just abstract this bit here and reuse it some day in the future...

My advice now... Don't do it! Just wait until the reuse case comes along, or the new feature request comes along, and *then* do it. You'll know so much more about the problem domain then, or you might avoid days (weeks!) of wasted effort.

NASA teamed with Armadillo Aerospace and Draper Labs ... to integrate and flight test a real-time navigation system in only seven weeks.

They probably just replaced their Waterfall software development process with something agile, like Scrum. :)

What's that, three two-week iterations with one one-week pre-launch crunch?

Yes, Django does have testing support, and Django itself is quite well tested - so I agree with you. The point I was trying to make is just that testing wasn't really a priority amoungst developers in the way it is in the Rails world. Things may have changed now.

As for talking about professionalism, it's more just a case of being fustrated by developers not testing their code - and it happens in all languages (and I do it sometimes too). It's just less common a problem in Ruby/Rails in my experience.

Slightly off-topic, but since a lot of comments are about how Ruby and Rails has nothing other popular dynamic languages and frameworks have to offer, I'd like to say there's one thing which drew me to Rails which I couldn't find in any popular Python or PHP web frameworks.

Testing. Craftmanship. Quality. This is more cutural than technical. While it's technically possible to write tests in PHP and Python, it just seems like people rarely do (especially so with PHP). And even if they do write tests, it's an afterthought. Things may have changed since I've done any serious development in PHP or Python, but I've done a little with Django and the testing that's done in the community didn't come close to Rails at the time. I'd be lucky to find a plugin authour whom had a test suite for their work and there was nothing of the function or quality of RSpec or Cucumber around.

This kind of lax "I tried it in my browser so it works" attitude to web software development in PHP and Python almost made me want to give up on web development and get into some other type of programming with some real professionalism - but thankfully I found Rails and glad that in general Rails programmers take their work seriously.

Having said all of that, I don't want to paint too negative a picture of Python. There are some awesome frameworks and communities in the Python world - Twisted/Divmod, for example, where the community really are bright and dedicated to test driven development. Zope 3/Grok is another. But I couldn't find anything in the mainstream web development world which were. Being mainstream is unfortunately important in getting anyone to support your descision - be they management, or a client.

I was going to mention Japan too. I remember after spending some time there and getting a train for the time since I'd gotten back, thinking how rude someone was for having a conversation on their phone on the train. I laughed about it once I realised my reaction but even now I still get annoyed by people having non-essential conversations on the train. Sure, calling someone to pick you up is no problem, but talking about your relationship problems for 30 minutes in front of a car-load of people? Maybe some people find it therapeutic.

I don't know... I have briefly tried freelancing but I can't shake the feeling of just wasting my time. I really don't like being a lone programmer sitting in my room trying to find ways to fill my time, doing whatever work I can find. Even if I go out, I waste so much time travelling from cafe to cafe. It's fun for a while, but when I really want to get stuff done, I *need* an office. Perhaps if I was freelancing in a shared office setup it would be different. I just can't work from home. I also miss things like having other people to bounce ideas off and larger projects.

Also, I found that I just don't like looking for work and worrying about finances. I want to spend as much as my time as I can actually writing software, so perhaps I'm better suited for employed life.

I find it interesting because I also see this trend towards freelancing, and the majority of programmers I meet are very happy with the lifestyle.

"There are numerous other Duke games in various stages of development, several due out this year. We are definitely looking to bring Duke into casual gaming spaces, plus there are other major Duke games in production."

So that's multiple major Duke games plus several smaller ones with more than one due out in 2010?!

Hillarious! It's like when you ask your friend starting a business on their own how that are doing and they'll say something like "Oh yeah doing great! Got a few things on the burner, with a couple of them looking really good, and few other interesting things going on." which really means "I have no work, but don't want to admit it" :)

Anyway, good luck to them!

Funny... I sent the link to a friend who does GRB-related research, and she said "thanks, I already know about it though, I'm one of the authors" :). Apparently there are 210 authors on that paper though. Imagine coordinating that.

Anyway, I don't know a thing about astrophysics so that's about all I can contribute to this discussion.

What Questions Should a Prospective Employee Ask? 569

Mortimer.CA writes "Even though things aren't great in the economy, it's prudent to plan ahead to when things (hopefully) pick up. In light of that, I'd like to update a previously asked question in case things have changed over the last four years: What do you ask every new (prospective) employer? When you're sitting in the interview room after they've finished grilling you, there's usually an opportunity to reciprocate. There will be some niche questions for specializations (sys admin, programming, PM, QA, etc.), but there are some generic ones that come to mind, such as: what is the (official) dress code?" Similarly, what questions should you avoid? Read on for the rest of Mortimer.CA's thoughts.
