We live in times of complexity, and even though neat technologies and elegant software can be found at times, the market is still definitely dominated by absurdly heavy solutions. Enterprise is imploding and a wind of change towards more sustainable approaches is blowing all around us, yet the mainstream scene is comparatively stagnant and all the pain inflicted to people is not really causing the deserved rebellion.
Why is that? Why when confronted by the possibility of rewriting their untestable bloatware, customer’s reply is almost always invariably “No, we don’t need it. We’ll just have to fix known bugs and add a couple of features, because right as it is, the software works ok…”?. What does “works ok” really mean? In my experience, it translates roughly to “The software does not physically blows up our office, it does some of the things we need to do, and over the years our employees have developed a thick skin against all the nuisances and a baggage of manual tricks, passed on by mouth, to get the rest of the work done anyway. Oh, and we already paid a lot for it”.
Recently, i got a taste of this mindset myself, when i booked online 2 tickets to Avatar at the local cineplex
“Hello this is my reservation code”
“Sorry Mr, those seats are reserved”
“Sure, by me”
“No, actually by others”
“What? see, i made this online reservation…”
“I see, but we take reservations both online and by phone, sometimes they overlap and phone is given priority”
“Overlap?! No trust me, i am a programmer, overlapping reservations are not supposed to happen, because your system has to take care”
“Oh, but evidently it doesn’t”
“WTF?!?!”
“Please, don’t get mad, i am gonna give you other seats. Today is not even bad. You should see how many angry people we must manage during christmas holidays when all movies are sold out!”.
Now, given that reservation means “An arrangement by which accommodations are secured in advance”, how would you rate a reservation system that does not guarantee secure accommodations? Like a fish unable to breathe underwater, yet they live with it, and this takes me to the point.
First, humans are best when it comes to adaptation. That means we naturally adapt to pain so that we don’t feel so bad, and adapt to pleasure so that we don’t feel so good. Perception of any external stimulus in the end comes to balance. Barry Schwartz in the Paradox of Choice says:
respondents were asked to rate their happiness on a 5-point scale. Some of them had won between $50,000 and $1 million in state lotteries within the last year. Others had become paraplegic or quadriplegic as a result of accidents. Not surprisingly, the lottery winners were happier than those who had become paralyzed. What is surprising, though, is that the lottery winners were no happier than people in general. And what is even more surprising is that the accident victims, while somewhat less happy than people in general, still judged themselves to be happy.
Second, humans are also very bad at admitting sunk costs. The idea of having spent money on something not worth is the ultimate inconvenient truth. Again Barry
Aversion to losses also leads people to be sensitive to what are called “sunk costs.” Imagine having a $50 ticket to a basketball game being played an hour’s drive away. Just before the game there’s a big snowstorm—do you still want to go? Economists would tell us that the way to assess a situation like this is to think about the future, not the past. The $50 is already spent; it’s “sunk” and can’t be recovered. What matters is whether you’ll feel better safe and warm at home, watching the game on TV, or slogging through the snow on treacherous roads to see the game in person. That’s all that should matter. But it isn’t all that matters. To stay home is to incur a loss of $50, and people hate losses, so they drag themselves out to the game.
Third, as brilliantly pointed out by Ryan Brush’s “Code is Design” in 97 Things Every Programmer Should Know and by Gabriele’s “Waterfall Pitfall #1″ (italian), uninformed most people understand software construction in terms of the better known building construction. Now, since programs are built out of bytes (not bricks), which are practically nothing, using mind (not excavators), which has no physical constraints, actual construction must be very cheap. This gives them the false hope of having an easy exit strategy at their disposal: fixing the software when an emergency comes up. Would they wait for a defective bridge to show the first cracks before attempting to fix it? Their unconstrained minds seem to be unable to realize that story construction aka book writing, built out of words, might represent a more fitting comparison and that The Divine Comedy took Dante, a renowned genius, more than ten years to finish.
Last but not least, mainstream has made a really good job at covering mistakes of incompetent programmers. From the almost sandboxed life cycle of a php script, to the rigid syntax of java and its self-correcting IDEs, to the plethora of useless certifications, great efforts have been devoted to make any primate with opposable thumbs able to program with very limited competence. Many and cheap, that’s how economy of scale is supposed to fail work, and that’s how we got this horde of unprofessional programmers sacking the best projects.
All of these points help to explain proliferation of crappy software. Maybe, they get it from some body rental which pays more for advertising than for the army of juniors that actually does the job. At the beginning it hurts, but they spent good money and cannot afford to accept failure, so lies are told and more time and money are invested to improve the situation. Then workarounds, albeit inefficient, come and direct suffering somehow decreases. Eventually, the pile of workarounds becomes part of company culture, and all is back to balance: the software starts working ok.
Unfortunately, this means that the quest for better software workflows can hardly come out of necessity, it must come out of vision, and vision takes inspiration fed to working brains then time for the masses to catch up. With Universe hopefully taking care of latter two, i like to think we, professional programmers, are those in charge of the former.
Until, from the midst of this darkness, a sudden light broke in upon me, a light so brilliant and wonderous, and yet so simple. Deep practice, eradicate errors and deep practice again. I alone succeeded in discovering the secret of bestowing skill. Nay, even more, I myself became capable of bestowing mastery upon apprentice matter.
