Pioneering computer scientist Dennis Ritchie has died after a long illness.
Mr Ritchie was one of the creators of the hugely influential Unix operating system and the equally pioneering C programming language.
A vast number of modern technologies depend on the work he and fellow programmers did on Unix and C in the early days of the computer revolution.
Those paying respects said he was a "titan" of the industry whose influence was largely unknown.

Without whom..many of us here would have to do something totally different to keep the wolf at bay.

Does anybody else think this guy deserves more recognition for the work he has done? Unix and C are generally the basics of the whole Open Source movement now.

Another industry giant gone - so sad. RIP, Dennis.
And yes, I agree, he deserves more recognition. Where would any of us be without what he did?
