That's true of any success.
For most people who end up highly successful at *anything* they have to put forth an effort that would described by most as 'crazy'.
Google has a special "Cluefulness Test" when it comes to IPv6: http://www.google.com/intl/en/ipv6/. In order to get IPv6 resolution, you need to register the source addresses of your nameservers with them, and claim/prove that you and your provider have "good" IPv6 connectivity to Google. You're also expected to troubleshoot any IPv6 problems that may occur, as opposed to your clueless users bugging Google directly about it.
If you don't meet those criteria, you're still welcome to use ipv6.google.com for searches, of course. But that's not the whole suite of Google tools/products, and the URL is just not as convenient...
That depends on whether you're running a Linux box at home in a "reliable enough" way to be functioning as a server. And in the example you give, as your primary machine as well. While I realize that many
I actually stopped doing it several years ago. I concluded that I have to maintain enough complex systems at work; I don't see any need to be a sysadmin for a complex system that requires nonstop patching and understanding of 30-year-old system internals at home, too. Plus the desktop environment was frankly primitive compared to modern machines. So I ditched it and started running OS X. (And I should say that I'm an experienced Linux sysadmin and engineer professionally, so this was not the "I don't know how to use it and it appears to have been designed by badgers" issue)
It's definitely true that, if you're already doing all of the work to run your own system at home, adding a DNS server isn't a big deal. But that's really a hobbyist thing to do. If your home system is primarily for the purpose of getting things done, rather than for playing with systems, it's an enormous amount of extra work. Yet having faster DNS lookups is still a win.
I believe the first consumer optical mouse would beg to differ.
An old Thermos that is of the glass-lined vacuum filled sort is dangerous, due to the potential of breakage.
Ah, brief. Much C was written in that jewel. It is the reason many of my text editors have been configured with blue as a background and white foreground.
