No, you've been mod'd down because you haven't read the article (or you know so little of the subject matter that you've misunderstood something very very basic.) The US Government is NOT about to "switch to IPv6". FWIW, your government is way ahead of my government in pushing IPv6. (You're right that Bush sucks fat hairy donkey cocks, though, but that's off-topic here.)
Well gosh, if only there were some method to map those long numerical addresses to arbitrary strings of human-readable characters. Hey, you may have hit upon a great business opportunity there!
This just requires that the backbone passes ipv6, which any backbone routing device made in the past 10 years will be easily capable of doing.
It's much less than that. Effectively the directive's minimum requirements are *one device* capable (not necessarily configured or connected) to route IPv6. So, BFD.
My "must watch" site-o-the-summer[tm] is The National Snow and Ice Data Centre with their horribly compelling weekly-updated map and chart of the total sea-ice extent. I've been printing the chart off every week and sticking it up on the wall; the idea being that looking at the chart as it'll be in late September is a different experience from looking at lots of individual charts showing the progress over the whole season. As you say, pure climate porn. (I also like reading journal articles where there are large chunks I'm completely unable to follow, but where the abstract uses terms like "unprecedented", "catastrophic", "tipping elements" and the like, yeah I'm weird that way.)
One particular season's worth of data in isolation tells us fuck-all about the future state of the climate, of course. In context with the gigantically irrefutable body of work around it, though, it's pretty damn depressing to be honest. If humanity dropped through a time warp tomorrow and popped out again in a couple of centuries time, ie there are no emissions whatsoever for that time and then we all pop back into existence exactly where we are today, the climate would still kill a significant fraction of the population with a few years.
Right. It must be very reassuring for the astronauts to know that if (FSM forbid) the stack were to blow up on the pad, the forward fire-fighting team going to dash into the burning wreckage and pull them out. I know it would make ME happy to strap myself onto an enormous pressurised tank of supercooled liquid hydrogen and oxygen.
Fortunately, both the SSMEs and the SRBs blow, rather than suck, superheated combustion gases. This effect tends to lead unsecured objects exposed to the blast to move away from the source of the overpressure.

Little-known fact: The Planet were the first ever retail ISP offering Internet access to the general public - from 1989. Hmmm, so the longest-established ISP in the world that they're not only working hard to get that DC back online, they're posting pretty open summaries of the state of play... coincidence? I don't think so.
Oh good god, that's just the tip of the iceberg. More likely would be to MitM some large corps' Outlook Web Access or other places where domain credentials are exposed (VPNs and the like.) Wait until you've got a domain admin's password. You now own that entire corp. Now rinse and repeat for government bodies. How hard do you think it would be for the proverbial well-motivated and resourced attacker to trigger off a war in such circumstances?
Then sit back cackling with glee whilst civilisation falls apart?
Seriously, in the last decade the premise that the Net is always there has become a silent assumption underlying a lot of critical systems. No I'm not talking about nuclear power stations being online, I'm talking about basic logistics chain outages that mean there's no-one there to run the power station, because they've no fuel for their car, because the petrol tanker driver is off scavaging food for his kids. There are a number of scenarios that could knock out the net (or at least cause widespread depeering, so you'd be stuck on your provider's network and unable to get traffic to/from anywhere else); it would be... well, a bit too interesting for my liking to see how things would go with, say, a seven day outage. Actually a 7 day outage might be just enough to wake people up to the importance of patching your infrastructure, having a heterogenous mix of code for all critical functions, oh and and enforcing BGP security.
Radiohead could sue him if he didn't properly license their song, though. Nonsense. You don't need the composer's permission to cover their song. You need to pay the publisher their dues, but you definitely don't need permission.
As horribly buggy as MSIE has historically been, Microsoft do at least issue patches reasonably promptly. They certainly wouldn't say "Nah, can't be bothered to fix that" about something like this.
I was going to say that IE seems to be getting slowly less buggy, but a quick check with CVE shows that's not quite true... I must have got that impression from MS' habit of rolling up fixes for lots of bugs into single patch / update. The bastards.
Yes; however (a) these are pulsed thrusters, with a very low (individual) power output, as thrusters go; (b) vertical vector velocity at touchdown is roughly 5mph, and (c) the thrusters cut out instantly at touchdown.
What does seem to have happened, interestingly, is that the upper couple of centimetres of dustry regolith has been blown clear in a big patch directly below the lander. The arm is designed to be able to reach down and image the underside (so that they can be sure all three landing pads are stable enough to risk moving the arm out to the side, potentially tipping the vehicle over if it were perched on a rock or something). That picture was taken with the (small) camera on the end of the arm, which is primarily intended to image the contents of the scoop as it digs. And oh look, that looks exactly like a big patch of ice!:)
(1) (a) In Star Trek, the galaxy is ruled by the Federation, a benevolent democratic agglomeration of worlds united for the common good. The protagonists are the crew of a Federation starship; although there's enough conflict to generate drama (plot), they are normally function as a well-oiled unit, with everyone committed to working alongside their crew mates to, generally, Do Good. (ISTR Gene Roddenberry saying something about wanting to show liberal democracy as a benevolent force for good - I'm sure ST fans out there can quote me chapter and verse or correct me. Whether it was intentional or not, the Enterprise is a clear metaphor for American geopolitical values and objectives in the 60s, or at any rate for the high school textbook version of same at any rate.)
(1) (b): In Blake's 7, the galaxy is ruled by the Federation, a authoritarian, semi-fascistic state with heavy Orwellian overtones of manipulation of the masses by propaganda and brainwashing technologies of various types. The agglomerate many worlds for colonial purposes; many planets are Occupied by the Federation whilst they are stripped of their resources, often by enslaving the local population. The protagonists are the crew of a spacecraft who all have their own agendas, but chiefly thrown together because they escaped from the same prison ship. Whilst Blake is a committed freedom fighter type, and attacking and destroying the Federation is their chief goal, several of the crew were imprisoned for non-political crimes. (Avon and Vila, computer fraudster and lockpick respectively, in particular.) The crew barely hold together at times, with Avon in particular openly plotting to leave Blake at various times. And who can forget Avon preparing to throw Vila out of an airlock to lighten an overloading ship?) The tensions amongst the crew, of which this is only the most obvious, are the motor that drives much of the dramatic tension.
(2) -- all the technology! The cardboard sets and props were totally believable at the time, most of the time (there were some stunningly lame "view out of a porthole" effects, and the supposedly computer-generated animations of things like scanner plots were completely lacking stuff that would be essential these days, like spurious data readouts and vernier markings, blinking alerts, etc. But this was before the days of mass-market GUIs, remember; it was only a year since the wooden mouth demo at PARC, IIRC. But the great thing about the tech was that it was almost never gratuitous; it served plot and/or character, sometimes in amazingly imaginative and ideas-based manner. Witness Vila's lock-picking tools, Cally's personal digital music player (in 1978!), Travis' James Bond hand (character devices); teleport - ok not original, but a fundamental plot device in many episodes (Avon getting himself captured, and holding out against torture until he's referred up to the Chief LaserProbe Merchant - at which point he triggers a beacon, and the crew teleport into the torture cell and kidnap the head torturer; and dare I mention IMIPAK, a gun which has no effect at all on the person shot (who may not even notice if they're not looking), until the user uses a remote control device to trigger the irradiated victim, who then curls up and disappears in a puff of bad light (or something - the nature of how the thing actually kills them is never described, because it's the McGuffin-like usefulness to the plot of having the audience knowing who's marked for death and who isn't, etc etc.
Just to name one, at the start of series 3 Avon is stuck on a beach on a remote planet, with the empty Liberator in orbit but uncrewed. He has Orac with him though (luggable supercomputer, which incidentally is a quantum computer although the term hadn't been coined then AFAIK!) Avon fires up Orac, uses it's long range comms to log into Zen, the Liberator's shipboard computer, and command it remotely to teleport him back on board. ISTR that there is mention of Orac's using encrypted communication protocols as well, so as far as I'm concerned that the first appearance of Ssh.
Incidentally, you might not have noticed it amongst all the great News happening around us, but oil is back knocking on the door of the all-time record high (yes, adjusted for inflation) set in April 1980. Strange the way timings go, isn't it.
also, the encryption isnt used to verify that whoever is sitting in front of the computer is who he or she claims to be, for that you have third party stuff like pads of one time codes, code generators and similar.
As Bruce Schneier pointed out, there's an important distinction between authenticating the transaction and authenticating the user. For ecommerce, the merchant needs to know that the card is real (for values of 'real' defined by PCI and similar standards.) The CC companies only care about the transaction; the transaction will complete successfully even if it turns out to be fraud, from the PoV of the CC company, because in that case it's the merchant who pays... and CC still get their money.
It's often forgotten that SSL/TLS provide authentication mechanisms as well as a crypto-bottled pipeline between client and server. In the common case, the client is supposed to check the credentials of the server via X509 certs. Hardly anyone uses client certs except in corp environments, where people can theoretically be trained about what they need to do with them. You can buy porn with a stolen CC, you can't work on the company network without the right cert, as well.
Several reasons for the different takeup rates for PGP, S/MIME etc vs. SSL:
There are far few servers to authenticate than there are peers, by a couple of orders of magnitude at least.
Running an SSL web server is significantly harder than running a plaintext port 80 one; whereas there's practically no difference on teh client side (checking the lock icon is still pretty rare (actually checking the ssl certs etc is a very minor sport.) Using PGP or S/MIME is kind of analogous to running an SSL webserver.
Much more money to be made from practical (==secure) ecommerce than there is to be made from secure messaging.
Interestingly corporates interest in secure mail transport (TLS, SMTP-auth etc) and I think S/MIME or PGP-type solutions are starting to trickle into production here and there a little faster than they've been trickling for the last decade.

Vista runs IPV6 by default
No, it really doesn't. Try connecting a couple of Vista machines via IPv6 only out of the box.

No, the launch was effected. I watched it myself.
Oh, and thousands of dull corporate brochureware sites.

I think the OP's referring to TSIG and it's variants.
Think about it.

That's a hell of cool image, but it's not going to be on posters on larval geeks bedroom walls for decades to come the way that the big HiRISE shot of the lander and it's parachute in flight, with Heimdal Crater in the background. That is a work of art. I can't understand why it wasn't on all the front pages the next day :(
Seriously, what evidence do you have to back up your assertion?
You think this is frightening? Just wait 'til you see what Zebedee and Dougal have got planned.
Well thanks, you just ruined my weekend.
