What does software engineering look like, in practical terms?
-
I'm actually thinking of writing an article entitled "Software Engineering is Dead", but I want to ask y'all, when you think of software engineering, how do you practice it in, well, practical terms? Anything from doing detail design analysis, prototypes (that don't turn into production code), design patterns, high level architectures like messaging, pub/sub, modular, service oriented, async, etc., all are fair game for what, in practice, "engineering" looks like. (Note how I snuck the idea of "high level architecture" into the idea of "engineering".) I'm also curious, for those with some level of college degree, did college teach you engineering skills, or did you learn them yourself or on the job? Marc

I personally don't think an app can be properly engineered in an agile environment. I'm self taught (aka, the Outlaw Programmer School of Software Development).

On the job - my University concentrated on teaching you the language, and some algorithms / in depth design (such as compiler design, OS design) without trying to instill the right "mind set" you need to "development as an engineering science" as opposed to "development as an artform". For what I see in QA, nothing have changed in that respect - except the in depth stuff has vanished in favour of "how to use FarceBook in VB" :sigh:

Yes but that would be basic. But most knowledge comes from applying on a real work environment and building your experience from project to project.

I keep seeing these posts here about software engineering is dead, developers don't exist anymore, yadda yadda. I have absolutely no idea what the blazes you guys are talking about. I've been a software engineer for 33 years and we are more busy now than ever before. It's insane we are so busy. Yes, developing systems in C# and SQL, and 100 other technologies linked together. We have to force ourselves to stop for most of today in order to interview 3 new candidates to join the team. The entire world is now software. Even my car runs on software. Software engineers are gods. As for your other question, I studied electrical engineering. Every single thing about systems and application design I taught myself, or from mentors. I have never stopped learning new things and exploring new technologies. When I get home, I switch to my home projects, mostly involving security, home automation, video streaming, communications, avionics... I try to sleep once in a while.

Don't ask me, I am a Klingon Developer. Someone, however thinks it is 'anything helpful to cope with the mess'. So, above all, well documented (or at least heavily commented) API, then, yes, prototyping and testing, and possibly design for testing.

I get the feeling that Marc's post has less to do with software engineering being dead and more to do with the cult of the script kiddies who seem to want to jump onto the latest shiny, rather than applying rigour and discipline to build and maintain systems. Marc has just been through a particularly bruising application of this where a well engineered system has been cast aside to allow the children to write a new Python based one, from scratch, simply because they have the CTO's ear.

The techniques used to build a treehouse* don't work when building a cathedral nor vice versa. The same is true of IT - you need to know what type of a thing you are building before deciding what techniques to use. Sadly in my experience in a very significant percentage of cases that first step is not taken. We decide the techniques to use based on factors external to what we are going to do with them - including external influencers (Gartner &c.) and existing experience. I learnt database design (Codd's laws) and object oriented programming at college. This was a long time ago but I imagine things like MVVM would be in whatever has replaced my course. Sadly I was also taught monolithic system design and it has taken me 2 decades to undo that. * This is not meant to be pejorative - I'm just illustrating the point. Personally I prefer treehouses to cathedrals :-)

I've noticed that. 30 years ago, my friend was graduating from UCSD with a degree in computer science, and everything he knew that was practical he had learned himself, particularly, modern (at the time) languages, tools, hardware, etc. 30 years later, I'm talking to a graduate of U. of Tennessee and the poor kid hasn't had any school exposure to languages like C#, and no exposure to modern tools (IDE's, debuggers, etc), again, anything he's learned he has learned on his own.

But that's point -- you're an engineer because you have 33 years of experience. But it seems that very few people, particularly (as Pete pointed out the motivation for my post) young script kiddies and CTO's that think they're programmers because they coerce a few open source projects to work together to build a website. Colleges/universities don't seem to teach engineering skills, managers freak out when you write code that uses a publisher/subscriber pattern, and Agile (in the ways I've seen it implemented) doesn't give a shit about up front design.

Got it. I see that too. You have swarms of high-schoolers who are only interested in writing games for iOS. But we've had that kind of people in our midst since the beginning. Important systems running on big hardware still run the world. I laugh at people who say the iPhone is replacing the desktop. If anything, I want my desktop system to be even more powerful. My friend just added a 43 inch monitor to his development workstation. I don't see myself sitting in a corner building systems on a 4.5 inch phone. Can you imagine doing AutoCAD drawings of a space station on an iPhone? I can't. Don't get me wrong, those toys are really cool, and I use one myself. But that doesn't take away from the real data processing needs of the world. And the infrastructure that runs those millions of iPhones are not running on little iPhones. They are running on real hardware. Built by real engineers.

The irony here is that because of hardware and browser hosting issues, Python got thrown out (I think) and it's being rewritten in F#. More irony. Particularly since the only junior guy, while he has FP experience, has never used F# and I had to tell him "if you use the debugger, you'll see that your property assignment isn't working because you need to use the
<-operator to make an assignment to a mutable structure, not the=operator. MarcImperative to Functional Programming Succinctly Contributors Wanted for Higher Order Programming Project!

Yeah. Irony: My son is now at the script kiddie age (14). So, his mom and I set him up with a VMWare platform with hosts running Linux. No GUI's are allowed. He builds and hosts servers from command line only. One year on, he's kicking ass and has paying customers.

Engineering looks like a pile of sheets with a lot of poorly drawn correct diagrams, awesomely drawn wrong diagrams, scraped lines, hastily written and more hastily forgotten "illuminations". Followed by smaller and smaller piles of similar sheets of improved quality. It's the most abstract and time consuming part, requiring focused meetings (not scrum, not at all) with the minimum necessary number of people and open minds - which means that after an hour everyone goes back to solo thinking and meet the next day. The only engineering skill that I learnt in college is to be as rigorous and factual as possible. Record all the results of the experiments, all the intermediate results and the procedures used to obtain those intermediate results and the indexes used for the decisions. Everything else is experience and personal initiative - the first requires time ("it takes a year to make a year of experience"), the latter is a tract, you have it or you don't have it. College also taught me methods to be factual and rigorous, in the form of Mathematical Analysis, Logic, Statistics and courses of Engineering - they are useful in that they make you design standard cases with the tools used to solve them the first time and then explaining how they were solved in the first place. Basically they are history classes on engineering matters. As for design patterns I have some trouble with the term because I have a colleague (self-taught) who misuses them on regular basis because deep down he does not understande them and makes things harder for everyone else. Then reasoning on the real meaning of the term I recognize that I use them as well, because THEY WORK, even if usaully in my team we prefer reinventing the wheel. We do embedded highly customized systems so it's usually the saner thing to do - standard components or pre-cooked desgin patterns never worked for us in the past 25 years.

Honestly I think it's a plus. Learning how to think, how to write algorithms and the hard science is more important than leanring the usage of tools. A properly trained mind can master any tool in a reasonable amount of time, even after paradigm shifts ot big technological changes. An ignorant mind who's been trained only in the use of some tools won't be able to adapt as easily. Of course every person is a world in itself so it's a GENERAL consideration. It's not the Education System that has to teach jobs for the companies, that is responsibility of the companies themselves. The Education System must create people, with the skills and mindset to approach their trade and life itself. In Italy we have Professional Schools, they are high schools that teach 5 years straight a trade, and we have Technical Schools, which are basically light engineering (up to 30 years ago the graduated students from those high schools were officially named Junior Engineers, with legal value). At the Technical University I (coming from a Technical high school) had the chance to confront with students coming from Professional Schools: they looked like monsters. They knew all the current tools and were able to quickly put up some sort of working... things. But they weren't able to design a simple algorithm or to learn plain C, because they were only trained to use a couple of languanges... of which they botched the exams. And they were anything but stupid, mind you. It's also the biggest chasm between Computer Science and Computer Engineering, at least in my city. CS students exit with many, many more "current" skills than us in CE. And quickly lose value and adaptability over the next 5-10 years. Our Technological University clearly stated that their most radicated goal is to make us as much tool-independent as possible.
