Perl 6

Not yet relevant for me. I just got rid of Perl 5.8, using 5.10 for daily work, considering update to 5.12. I won't use Perl 6.0.0.0, I will wait until things settle and we see something like Perl 6.2 or at least 6.0.2.0

IPv6

Played with it in a university lab. Considering to play with it again, now that things have settled. But not relevant until my provider offers and advertises IPv6. I currently use exactly two public IP addresses, one shared with many other people on my shared webspace, and one for my DSL dialup. And I don't think I need more public IP addresses. My DSL router uses NAT, so I can use thousands of private IP addresses in my LAN, and no one from outside my LAN can access machines inside my LAN unless I explicitly forward ports. The IPv6 people say that this is wrong, that all of my machines including my microwave oven, my dish washer, my alarm clock, and my vacuum cleaner should have (public) IPv6 addresses. I don't like that, so I would set up IPv6 in a way that my DSL router would do IPv6 NAT. So I would end with exactly the same situation: One public address and as many private addresses as I want. Currently, IPv6 has only disadvantages for me: extra work and for most stuff, IPv4 is still needed, while IPv6 does not gain anything. It will change in the future, but until then, I will continue using IPv4.

HTML 5

Well, HTML 4 plus a few new features, like audio, video and more input types. Plus a nice and short doctype declaration. I can't wait to see modern browsers support it, together with CSS 3. Until then, I will stay with HTML 4.01 strict or transitional, plus CSS 2, plus JQuery. Backwards compatibility for the new features of HTML 5 in old browsers will be an interesting problem. Especially the new input types, that will all fall back to a simple text input in old browsers.

Power Shell

What's that? And why the heck should a shell mess with windows? bash has everything I need when I need a shell.
