In three letters: NIH. Management decision was that all IP had to be 100% owned by the company and had to be in 'C', in spite of an enormous amount of friction between C and the project as well as a bunch of work by others that could have been leveraged if we had decided to use code from other contributors. I got called in long after these decisions were made and it was very clear they weren't going to budge on those. There is a lot more to this story but I'm not at liberty to tell. Let's just say I learned a lot.

So you had to write your own compiler, operating system, and runtime libraries too?

-- I know, you didn't think it made any sense either. I'm just pointing out that a line has to be drawn somewhere; where it gets drawn is actually arbitrary.

Yeah, I've had to deal with ridiculous mandates from on high too, though none anywhere near that onerous. In my previous job, we were writing a compiler. It was mandated to be in C++ -- the first mistake -- and we had to use smart pointers instead of GC -- also a mistake. But the completely idiotic thing was that we were not allowed to declare any exception classes. The VP of Engineering -- a very smart and experienced but very arrogant guy -- had seen exception hierarchies get out of control before and decided the solution was to ban them.

But that's on a pretty small scale compared to what you're talking about.

I tried that line and it did not work.

[ScottBurson]

Huh. I wonder how they defined what was acceptable and what wasn't.

Oh well, I'll be fascinated to read the book if you ever write it.

Reminds me of my last^2 job: we were using Scala and the "technical architect" made two decisions that were mildly wrong in isolation but interacted rather badly: we'd make heavy use of monads for core functionality, and we wouldn't use scalaz. So I spent a while reimplementing parts of scalaz, and learned quite a lot (though I doubt I was adding much business value while doing so).

[Argorak]

So, the implementation was "conservative", but on a very different level.

Sorry, could not resist.

[jacquesm]

No, no need to apologize. It's one of the strangest assignments I've ever had and there were a few twists to the whole story that would make for a good book.
