What's the nicest way of doing clientside form validation without annoying the user? I keep finding forms that show red errors when I write 'wilfred@' for an email or '0' for a telephone number because I haven't finished inputting the value.

Which programming languages are the closest to 'finished'? In other words, which are unlikely to expand core features or syntax such that best practices change. C and Scheme seem to fit this, are there other languages?

I haven't found a nice way of reporting "N/N tasks done" in progress interfaces. Users don't like seeing "Baking cakes 10/10 (100%)", especially if the last cake is slow. It's weird to them to see 100% when you haven't finished, but mathematically it's logical.
