[LINK] 10 tech laws that define our world

Ben - among engineering authorities (eg, Engineers Australia), I believe 
the status of 'software engineer' remains contentious. Someone can 
correct me if I'm wrong there...

As for project sign-off: no, people can just "finish" their software and 
say goodbye, without a sign-off from someone with engineering accreditation.

I certainly know about civil engineers and bridges. My brother's last 
sign-off before retirement was the Grand Pacific Drive.

(Aside: When I discussed the NBN with my brother last year, treating it 
as a civil engineering project, his response: "If you have the chance to 
do it sooner, do it sooner, because it will always cost more if you 
wait. And if you have the chance to build it to last longer, do it, 
because replacing it will be more expensive later."

The bridge portion of the Grand Pacific Drive is rated, with normal 
maintenance, to last for 70 years. In civil engineering assumptions, 
that means it should probably be good for about 200 years. Although the 
nominal life of the NBN fibre is 30 years, there's no physical reason 
the glass won't last somewhere between 50 and 100 years. In that 
context, I find the political excitement about the cost to be ludicrous.)
