Samsung Shows Off Galaxy Tab, Android Allegiance
I have an unlocked Verizon android device (HTC Incredible) that I can run anything I want on. He may be "new", but you're misinformed.
YouTube Revamp Imminent?
It doesn't and it shouldn't. The problem is that browser makers can't decide which codecs to support.* A current list of which browsers support which codecs is here: http://diveintohtml5.org/video.html#what-works
*I still don't believe this is much of a problem though. You can specify a fallback format if the browser doesnt work with your preferred video format.
Google Chrome Extensions Are Now Available
AdThwart works fine. I've been using it all day and have yet to see an ad.
The Perl 6 Advent Calendar
24 ways takes a general forus on web development while PHP Advent is supposed to be  more PHP focused.
 Though that doesn't seem to *actually* be the case...
Opera Unite Web Server Benchmarked
Opera Unite is not as decentralized as you may think. It still requires that you initialize connections via the machinename.username.operaunite.com domain that you are required to register with Opera. Sure, this is set up to easily traverse a NAT, but it isnt as decentralized as advertised (and you're restricted from hosting content that they consider "obscene, vulgar, hateful, threatening, or that violates any laws".
A more thoughtful take on the subject can be found here: http://factoryjoe.com/blog/2009/06/16/thoughts-on-opera-unite/
Palm Pre "iTunes Hack" Detailed By DVD Jon
I honestly don't think Apple will care much. It leads to more people buying things from iTunes after all and cements the dominance of iTunes for managing media. Perhaps they even did this in conjuction with Palm... if you think about it they would have been smart to do so.
Think of iTunes as a driving force between iPod sales rather than the iPod as a driving force behind iTunes sales and you'll understand why Apple may be against this.
Should Wikipedia Sell Advertising?
Wikipedia should not be used in academia, but the usual reactionary attacks ("OMG! Anyone can edit it! Its unreliable!") aren't the reason why.
Students shouldn't be citing Wikipedia because it's billed as an online encyclopedia. University students shouldn't be citing any encyclopedia at all including Encarta, Britannica, Wikipedia, etc. Encyclopedias paint a broad picture of a subject and can be used as a starting point in research, but they shouldn't contain any original research and thus shouldn't be used in academia, especially at the university level.
Actually, I think Wikipedia would have a hard time getting universities to pitch in - most professors I know don't quite understand it, and absolutely abhor its use. I know of professors who will fail an assignment citing it as a source.
