Don't forget, open source code is as often not formally proven as commercial code!
Sorry. I cannot parse that sentence?
Actually, neither makes sense to me. Nobody formally proves software outside of academia. Even then, that small subset that are formally proven tend to be tiny snippets implementing convenient algorithms on idealised systems, with no time pressures, which if costed at commercial rates would be ruinously expensive.
In reality, it doesn't matter, because when I use the phrase "commercial code" I mean code that is written to be used commercially, as opposed to code that is written for academic purposes; and that includes open source software.
The nearest equivalents in the motor industry are those design prototypes that they show at events like the Geneva Motor Show, that never get into production.
If one car in 50,000 displays a warning light when it shouldn't, the manufacturer recalls millions of them. Just in case.
Great example, but wrong argument!
I whole heartedly agree that the state of the software industry hasn't yet reached the maturity of the car industry when they were building Model T Fords; and I lamented the typical software disclaimers and what they say about this industry in Re^5: Programming is more like:
Car designs aren't proven mathematically. They are tested. Often to destruction.
As an example of the futility of trying to use maths as the ultimate design tool for cars, in late 2009 Virgin Racing set out in to design an F1 racing car using only Computational Fluid Dynamics. After two years and close to £100 million during which they rarely came anywhere but last, they recently announced that they were abandoning that policy and are going to rent expertise and facilities -- particularly wind tunnel time -- from one of their competitors.
And cars, even F1 cars, probably have less "moving parts" than the (fairly modest) editor I use, and certainly far less complexity than the browser you are viewing this in.
