Scientists Solve 2,000-Year-Old Mystery of Incredibly Strong Roman Concrete and It Could Help Battle Climate Change Modern concrete, including its vital ingredient Portland cement, is a major source of greenhouse gas emissions. But it could all change with a new discovery. Our obsession with concrete accounts for around 5 percent of human-induced emissions. A third…

C isn’t a programming language anymore • The Register
C is often praised for being “close to the metal,” for being a “portable assembly language.”It was, once, but it hasn’t been since the 1970s; the underlying computational models of modern computers are nothing like the one that C represents, which was designed for a 1970s 16-bit minicomputer.

C is not just a programming language, it’s also an Interface Definition Language or IDL. IDLs are very important – as we quoted back in 1999, “the CORBA Interface Definition Language IDL is… ‘one of the most significant contributions in the history of computer science’.”
