The difference is that with an OS-licensed backend, you can counter FUD with one line -- "Here's the licence". Without it, you have to go into the extended discussion we've just had, with so many opportunities for misunderstanding and confusion. And yes, D would probably continue to suffer some FUD in the short term even with a backend licence change, but not in the long term -- look at the history of Qt for a comparison. GDC and LDC solve _one_ problem -- the problem of developing D programs using purely open source tools. But they leave remaining the problem of contributing to the core of D using purely open source. That's not a problem that is urgent to address right now but it is a problem that probably needs to be addressed at some point. > The situation can't really be fixed, so I don't see much point > in trying to spend a lot of time and effort trying to fix it. Not for now, certainly. I do think, though, that it's worth having the detail of the issues involved laid out and understood. That allows for some longer term planning and thinking around possible solutions. |

So far, I've found that easier said than done!
Perhaps if I really sat down and worked it it'd be better
though but it is just boring.

Oh, I wish I could take time off and hack away on a Pi !
I've always wanted a computer that had no fan and used only a handful of watts.

I don't know what I'd do without meld these days. It's one of the most useful programming tools to come down the pike in years!
There's a workalike on Windows called "winmerge" for those who develop on Windows.

But nobody makes a *desktop* fanless arm machine.

You could use a beagle board or a panda board as a desktop computer.
