Moreover, the person who discovered them should have every right to name them wahtever he/she wants
Herschel originally named Uranus "George's star" in honor of King George III of Great Britain. Let's go back to the name he wanted, and make a thousand Slashdot comments obsolete!
Just for your info, guys: I just visited the article and removed the offensive terms, also leaving a small explanative note about the term itself just in case someone hears it again knows what it is all about.
You edited a version from April 7th and therefore you overwrote all the edits people have made over the last three months. You also managed to miss about 10 stray "Polacos" scattered through your old starting version of the article. The article was reverted and had no "Polacos" at all, but it now seems to have been reverted to your version again.
I hope you will have a long and happy relationship with Wikipedia, and get an account there
I was pretty sure that there were more than 65,000 BGP AS numbers in use
No - here are the details of the 40,000 or so AS numbers handed out by IANA. There is also a set of weekly statistics posted on NANOG which shows that 21,484 of these AS numbers can be seen in the global routing table. Only 8,867 of these guys advertise a single prefix, so to get 181,747 routes there are a lot of ASes advertising multiple prefixes.
Not true. Major carriers have OC192 (10Gbs) links in their backbones running Packet over SONET (POS). ATM cards are way more expensive and don't go up to such high speeds on Cisco and Juniper routers. Typically carriers would have swapped out their OC12 ATM for OC48 POS five years ago and have just kept augmenting since then.
That would be the experiments of Weber described in the sci.astro FAQ
The "something else" that was observed was most likely to be big ordinary vibrations which the experiments were trying to subtract to leave a small signal.
I thought Martians were supposed to send landers HERE in groups of three
Does anyone remember the 70s TV series UFO? Earth was protected by three space-fighters each armed with a single missile. Oh, and a moon base staffed with English women in purple glitter wigs and short silver skirts. If only 1980 had really turned out like that!
These cable companies have Tier 1 upstream providers. For example, NTL has Level 3 and Sprint for reachability to/from destinations it can't get to with settlement-free peering, while Comcast has AT&T as an upstream. We are talking about many Gbit/s of downstream transit traffic, and the cable companies are paying for it based on how much traffic they pull. They pay for the larger of the traffic flows, and as the larger flow is downstream it is not "essentially free" - they pay more themore they use.
Oops - I didn't realise they have some free articles and some that aren't.
To summarise from the article in the (excellent) paper version of the magazine, the trick is to use heavy metals like lead/bismuth as the coolant instead of water or CO2. This leads to higher energy neutrons which can turn some of the troublesome waste products into more benign isotopes (sometimes via very short-lived ones). The reactor can also use thorium, which is plentiful but not too much use in normal temperature reactors.
American Scientist magazine has an article on "heavy metal" reactors that transform some of the nastiest components of spent fuel into a more acceptable range of isotopes.
Dirac was renowned for being taciturn (the joke was that a "dirac" was the quantum of speech) so perhaps this was the inspiration for using his name in the context of compression technology.
For your point (3), the routing table size could be smaller for IPv6 than for IPv4, due to a combination of starting off with a clean slate and the vast quantities of addresses represented by a/48 (the typical unit they are doled out in). The IPv4 routing table size is more than 150k networks, but from only about 30k autonomous systems. A lot of these people have many separate routing table entries in IPv4 for historical reasons only. This isn't to say it couldn't get big for other reasons later!
The overhead hit isn't quite as bad as you suggest for typical HTTP content. The packet size is typically >1300 bytes and IPv6+TCP is 60 bytes compared to IPv4+TCP at 40 bytes. I make that 1.5% for real data transfer
People have recognised this problem (track by last 64 bits) and the solution is to generate random temporary addresses and use them instead - http://www.faqs.org/rfcs/rfc3041.html
It seems like minority parties (at least in the UK) really do care about these 'wasted' votes. If they get 5% at one election, 7% at the next, 12% at the next, then it really energizes them and gets more press and public interest too. Places that used to be safe for one party can become marginal. Although 5% of people thought their votes were meaningless at the start, it turns out they weren't.
However, if everyone applied your reasoning then I guess this sort of thing wouldn't happen.
No major backbones carry IPv4 tunneled over IPv6. You might be thinking of MPLS which is present in a lot of backbone networks.
It's hard to believe there is 'heavy' use of IPv6 when the dedicated IPv6 exchange in the UK peaks at 4Mbit/s of traffic and the LINX exchange in London has >30Gbit/s of IPv4 traffic

Sideshow Bob: "Attempted murder?" Honestly! Do they give a Nobel Prize for attempted chemistry?

So Slashdot readers need to apply tinfoil to their wallets as well as their hats...
