How not to codeby brian_d_foy (Abbot)

Most people seem to most enjoy the actual coding part of the software lifecycle. Some people may have heard of design, and even non-programmers know about this part called debugging. It's the creation of new program statements that is the most fun though, and since it's so fun, we gravitate towards that part of the process and do it as much as we can. Damn the torpedoes!
This isn't a complete list of code avoidance techniques, and I'm sure plenty of monks will have their own to share.
This meditation is about taking all the fun out of programming. The fun part causes all the problems: it's the one the creates more lines of code which leads to more bugs and more work for maintainers and documenters. Life would be grand if every task could be expressed as a screenful of code (assuming that we don't have to worry about any of the code behind the statements we actually see). We'll never acheive that, but we can still work towards it.
For this meditation, I mean "programming" in an over-arching sense, including the entire development cycle, including the boring bits. I mean "coding" as just the bits that involve typing new statements.
"Not programming" means not coding when I don't need to. It's more than not reinventing the wheel, or Laziness. It's not about code style, code re-use, script archives, or any other source of code. It's also not about refactoring or reducing the amount of code, because that's coding too. "Not programming" means not doing anything. It means not creating more code, however we acheive that.
Do something else
The trivial solution is probably the most fun and the least well-paying. Just don't code. Play Quake. Watch a movie. Do something else. You could even do what I'm doing right now: write something for Perl Monks. It's a colossal <s>waste fo time</s> procrastination leverage technique that combines the synergies of the ... sell it anyway that you like, because you probably already know how to. This isn't a meditation on writing though: it's about not coding.
Don't get interns to do it for you
A lot of people see interns as less-than-minimum wage workers who will do just about anything to get a good letter of reference. Give them any real work to do and they'll probably take three times as long as anyone else and you'll have to redo it yourself anyway.
Of course, with proper supervision, interns and junior coders can do a lot of good work, too. They can pump out a lot of lines of code for a little bit of money. Don't think that they are just coders you pay less, though: how many of those lines did you actually need?
The same goes for outsourced programming: you can't expect good results when you dump something into the laps of people you have never met, never talk to, and generally ignore. Despite what managers may tell you, this does not save you money. Often it costs more, and you end up coding it yourself, and that's what we're trying to avoid.
Don't rush to code
If you don't want to do much coding, don't be in such a rush to code. Pressure-ccoker shops that need one-offs in 15 minutes (yes, they exist) don't count, just as many other situations will not fit this.
When we start coding before we really know what we want to do, we often end up with something we don't want or is a lot more than we should have to maintain.
I used to have a guide at one of my workplaces: a good idea will still be a good idea in three days. Not only that, you'll still want the good idea is three days. The fair and bad ideas will sort themselves out in your head within that time. You'll either see the downside or just forget about it completely. In that case, you didn't do any work.
Of course, we don't want to go the other way either. We don't need to make all sorts of fancy diagrams, UML charts, story cards, or any of the other things that delay coding.
If it ain't broke, don't fix it
Some people can be satisfied with ugly, kludgey code. Some people can't sleep at night unless every equal sign lines up correctly. Guess who spends more time programming (I don't know either: one probably spends more time debugging while the other keeps fiddling with things that don't make the code work any better).
If the code is doing whatever it has to do, let it alone unless you really, really need to change it (see the "Three Day Rule"). There is usually enough work to go around anyway. Do something else. Delay and evade pressure as long as possible.
Inherited code is another story. I haven't heard too many people rave about the beauty of the code dropped in their lap. More often than not, they complain about the long gone employee who was the only one who understood the code, or why anyone would try to code FORTRAN in Perl.
It's probably already there
A while ago, I thought "Wouldn't it be great if I could process a whole directory of Template files all at once?" I almost started to write the simple scrip that would be able to do it, but then I thought "I bet someone has already done this." Indeed, Template comes with ttree, which does just that.
There are probably a lot of things that you already have and just don't know about. Find and use those things.
Redefine the problem
Sometimes I can simply re-define the problem. Does this really need to be so complicated? Why are we really doing this step? Business processes develop over time through the hands of many people, some of which may have become a faded memory. The process keeps going because it has always happened that way and everyone assumes that everyone else wants it to happen that way.
Consider a social solution
Along with a problem redefinition, there might be a better way to re-arrange the people portion of the problem. If everything were just technology, wouldn't the world be great? We could solve all of the problems pretty quickly.
I get to see a lot of different situations since I get to visit so many companies while working for Stonehenge, and one of the most common situations is that the programmers don't work with the system administrators, or the other way around depending on which side you take. If that weren't enough, throw database admins into the mix, because they count themselves as a separate group. There might even a couple of levels of management in there, or even worse, grumpy off-site telecommuters.
It doesn't matter who's who, who's right, who's left, or who's to blame. Most likely the different groups don't even really know each other. They may not have even met. Companies and universities can be big places, so people are spread out. A lot of programming may just be working around something that someone else has set up. In some cases, they might have no particular attachment to that set-up (or, more likely, they do).
People tend to work better together when they know each other. People tend to work better with you when you've helped them out in the past. They work really well if they are drinking buddies. Maybe the solution is really just a night at the pub with the right people.
Get a different job
No, really: get another job. Many programmers promoted into a managerial career path find they no longer have time to code. And they probably get paid more.
