More Than Coding Errors Behind Bad Software
An anonymous reader writes "SANS' just-released list of the Top 15 most dangerous programming errors obscures the real problem with software development today, argues InfoWeek's Alex Wolfe. In More Than Coding Mistakes At Fault In Bad Software, he lays the blame on PC developers (read: Microsoft) who kicked the time-honored waterfall model to the curb and replaced it not with object-oriented or agile development but with a 'modus operandi of cramming in as many features as possible, and then fixing problems in beta.' He argues that youthful programmers don't know about error-catching and lack a sense of history, suggesting they read Fred Brooks' 'The Mythical Man-Month,' and Gerald Weinberg's 'The Psychology of Computer Programming.'"
After working 3 months at my first programming job, the other two developers quit which left just me. I felt inadequate until I started interviewing other programmers to fill in the gap. Apparently lead developers with 10 years of experience can't solve the simplest programming problems, explain how databases work, or explain OOP. I'm convinced that most software sucks because most people writing it have no idea what they're doing and shouldn't be allowed to touch a computer. I'm currently in my 5th month at the same job and we've got someone good who will start soon, but it took a long time to find even one competent developer.
Quite dead on. But the difference is that today, with all the RAD tools around, you have a fair lot of "programmers" who don't even know what they're doing and get away with it. They got some course, maybe at their school (and that's already the better ones of the lot), maybe as some sort of an attempt to get them back onto a job from their unemployment services, and of course tha intarwebz is where da money is, so everyone and their dog learned how to write a few lines in VB (or C#, the difference for this kind of code molesters is insignificant) and now they're let loose on the market.
Then you get hired by some company that signed up those "impressively cheap programmers, see, programmers needn't be horribly expensive" when the project goes south because deadlines lead to dead ends but no product, and you're greeted with code that makes you just yell out WTF? You got conditional branches that do exactly the same in every branch. You get loops that do nothing for 90% of the loop time and when asked you just get a blank stare and a "well, how do you think we could count from 80 to 90 besides counting from 0 to 90 and 'continue;' for 0-70?", because that's how they learned it and they never for a nanosecond pondered just WHAT those numbers in the 'for' block meant. And so on.
Granted, those are the extreme examples of people who learned programming like a poem. By heart. They have a hammer as a tool, so every problem has to be turned into a nail. But you'd be amazed at the blank stares and "what do I need that for?" when you ask some of those "programmers" about hash tables (include snide joke about Lady Mary Jane here...) or Big-O notation. And we're talking people who are supposedly able to write a database application here.
This is the problem here. It's not youthful programmers. It's simply people who know a minimum about programming and managed to trick some HR goon into believing they could actually do it.
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
The fact is that software development is very difficult. I think there are several reasons why it is more difficult to develop robust software now than it was 20 years ago. Some of these reasons are:
I'm sure there are more causes and other folks will chime in.
I'm an old timer, still working on IBM zSeries mainframes, mainly. We just got a new system, which runs on a combination of Linux and Windows servers, to replace an application which used to run on the mainframe. Nobody likes it. We are apparently a beta test site (though we were told it was production ready). It has a web administration interface. For some reason, on some users, the only PC which can update those users is my Linux PC running Firefox. Nobody can say why. Until early last week, it would take a person a full 5 minutes to login to the product. They made some change to the software and now it takes about 10 seconds. this is production quality? No, I won't say the product. Sorry. Against policy.
