The US government wants developers to stop using C and C++

Re: Why?

While it's true that Rust has no inheritance, there are traits and supertraits that allow polymorphic behaviour.

This was apparently an early design decision to avoid the classic C++ diamond inheritance problem, but I've not used the language enough to understand if the same problem exists in a different way through traits.

So far I've not seen anything in Rust that couldn't be achieved in C++, the difference is that a C++ programmer would need the right disciplines to create Rust-like behaviour (not enforced by a compiler) whereas Rust forces the coder to follow the regime.

Will it turn out to be the next "fad" language? I remember learning (and loving) Ruby, though that didn't live up to its promises in the way that Rust has - so far. We will have to wait and see.

Seems he's not planning on leaking the DB.

He also says, "most of the time there's no REAL malicious intentions". Some of the time it is malicious then? What a lovely guy.

Re: Why not diesel?

It could all be used for fuel.

The process cost is tiny for biodiesel production, for me it's 10 pence per litre all in (chemicals and electricity for heating/pumping/Methanol distillation) and I'm not doing it on a large scale. The main costs are the feedstock and duty. I'm constantly being pestered by Chinese companies trying to sell their used oil in 14 ton loads, so they must have lots of it if they're willing to ship it around the world.

I can see the problem with aviation being the variability of the feedstock, and the many thermal characteristics of the final fuel. Unlike fractional distillation which gives nice uniform grades of hydrocarbon, biodiesel has a wide spectrum of fatty acid chains, each with their own cold filter plug points. Add in problems with oxidisation to contend with and it can be a world of pain. Sadly theregister article is a bit light on the technical details of what this company are doing that would address these issues.

Good luck with that...
