I am Greek. From our ancient civilization (you know, the one that invented democracy and other pesky things:-), besides statues, buildings, temples, swords etc there is left an incredible amount of literary works. What's funny is that I can read most of it and understand what it is saying. Of course, Ancient Greek is being taught at highschool, but even it it wasn't, I would still be able to get a very good feeling of what I am reading. Modern Greek is very close. At the same time that some other civilizations' remains can hardly be decrypted, our heritage is being studied by thousands of scholars and philosofers around the world.
So, if, for example, we want to make sure that the heritage of our collective Western Civilization survives, we must make sure that our languages are preserved(*). I know this sounds like a "no shit, Sherlock" argument, but I think it is a matter of basic school education. All children MUST have rigid foundations that will allow them to speak AND write correctly. This also goes to all technical studies advocates too who think that a laptop at the age of 7 or 8 is surely a good thing. If you take up all their time with stuff like that, they'll never want to or have the time to receive such basic education, which in my oppinion is crucial. Well, at least as crucial as learning computers in our modern age.
I may be wrong, but think about it.
(*) Note to ourselves: Also, we must make copies of everything like there is no tomorrow. And not encrypted (or DRMed) copies, just plain unencrypted copies. That will make sure that nothing is lost during the course of time.
It is clear from the article that they are aiming for something more than OSPF or other link state routing protocols. If a link is cut inside a network, OSPF adjusts so that traffic is routed through alternative paths. But, until there is convergence (which is quite fast in most cases), packets may be lost. Packet drops do tend to occur if a router cannot find a suitable route to a destination, if it is able to find a route but the link to that route is down, or even if the queue on that link is congested (full). That's the very nature of our present best effort internet.
It appears to me that these guys try to address some of these "shortcomings" by making certain privisions that can guarantee packet delivery, even in a overly late fashion. A routing instability, lost routes or links should not be able to cause packet drops if they have it right.
However, I used the quotes in "shortcomings" because I am not entirely certain that this has not been tried before. If, instead of a best effort packet routing service, you try to invent a "smart" network layer that can guarantee stuff like ordered delivery (packets are delivered in the order they departed), assured delivery (even with great delays) etc, you are basically trying to invent a (gasp!) connection oriented service. Not that connection oriented technologies are inherently bad, but, well, they are certainly an order of magnitude harder to implement. Anyone remembers OSI? It might as well be easier to leave IP simple as it is and try to move some smartness to the upper layers.
Additionally, it would be better to try to build on top of unreliable services like IP and construct stuff like SMTP (as a previous poster very cleverly pointed out), that can function even if parts of the network are mulfunctioning.
Well, anyway, you might want also to take a look at the efforts on the interplanetary internet, this article reminded me of it.
Although the article specifically states that this is a windows solution, I think it's worth noting that sunray works exactly like this. You put the smartcard, your previous desktop session is instantly restored, you do what you want to do, you pull out the card. Your desktop session is preserved and is terminal independent.
As for the lack of windows applications, it is actually possible to do it even on sunrays , although admitedly it is not particularly suitable for the small scale that the article submitter implies.
Anyway, you might take a look at those two links, and if you must absolutely use PCs (sunrays are more suitable for the job the article is outlining), take a look at citrix also. I don't know whether they do smartcards though.
To me, KML is the single most insightful feature Google Earth has.
I can share the KMLs with my friends, script programs that produce KMLs on the fly, backup my placemarks, post KMLs on forums, I can even display KML on Google Maps.
Until this Virtual Earth thing supports KML (and no, an alternative binary closed typical M$ format will NOT do), it's useless beyond 5 minutes of eye candy happiness.
Obviously it is not illegal. The guy was set free the next day. And after all this publicity, I suspect that he will have no problem being acquited in trial.
This is yet another example of litigation used as a means of threat. Unfortunately, this doesn't happen around Greece only. The guys that started all this probably don't have a chance in court, but they sure caused a whole lot of trouble to that guy. I only hope that he will countersue them for moral damage and demand a shitload of money in compensation.
There are methodologies that can ensure that certain types of actions cannot be done without two admins working together. Can this be done for the action of reading someone elses email? If it was possible, they would have to conspire to read the bosses email. Anyone has any good links?

Well said. And there is another point: There are places where SciFi is not available. Example: For a person that lives in a small country, the demographics are too tight for a channel like SciFi. So, we don't get to see Battlestar Galactica and the producer doesn't get the added revenue in his/her pockets.
As a friend of mine recently pointed out, the long tail has proved a very successful prospect for internet based companies, because of the pervasiveness of the Net. Shows that otherwise would get no audience and hence get cancelled, would be able to succeed that way.
Apple arguably realizes that, they know that there is a goldmine under their feet waiting for to be tapped. If they can transfer the iTunes model of operation to a set-top box in the living room they could make insane profits. The only issue is that they need to be carefull not to make it cumbersome to use. But this is apple we are talking about, they own the personal music player market because they know how to make simple and easy products.
The only real constant in life is death. It doesn't matter whether you are rich, poor, stupid, smart, black, yellow or white. You get to die like anybody else. Religions are based on this fact. If you think about it, people are much more tolerant on one another because they know everyone eventually ends up in the same place. Which they perceive as final justice.
If you are to invent a way to live forever, all these will be lifted. I think it would take away all those moral barriers. That would most certainly lead to violence and war.
Um, at least Solaris makes great efforts to make sure that an application that runs on Solaris.X will be able to be transfered seemlessly to Solaris.X+1. Thats one of the reasons there's all this legacy staff lying aroung in various directories. If you look at Solaris man pages, there's usually a note about whether the interface is stable and whether it will remain in the next releases. Even the output of commands tends to be relatively stable across releases. And of course there are cases of drivers (for example network cards) that are compatible across Solaris.8,9,10 because they were written according to the guidelines. Even the migration to 64 bits (on SPARC) has been done a decade ago. So, if you invest on it, chances are that your software will probably be able to be transfered unchanged to the next version, when it is around.
Linux is great, don't take me wrong, but in what way your intellectual investment is safe, when the entire landscape is in continuous flux? I mean, APIs are changing back and forth, kernel modules come and go across minor kernel releases, each distro has its favorite places where commands and files are placed. Not to mention the 32 to 64 bit migration which is in a terrible mess. This is not MHO, read July's Linux Journal editorial and laugh about it.
The truth is, I don't think you are not interested in any kind of intellectual investment, you are just betting on a horse because someone told you that in the end there can be only one. Well, guess what, "they" 've been saying the same since 1985, and today there is still Windows,Linux,all the BSDs,Solaris,AIX,HPUX etc etc. They aren't going anywhere anytime soon, and, really, it is great to have such a diverse ecology.

For large installations (read: hundreds of thousands of users) one might also want to take a look at the Sun Java System DS (former iPlanet), which is a very trustworthy and feature rich solution from what I've been told.

Hmm...I am not sure how you could work it out without a link state protocol like OSPF.

In don't have a proof handy, but intuitevely I have the feeling that unless the links on the mesh network provide some insane amount of bandwidth, there is a certain limit to how many nodes (of course it would depend on topology also) can operate smoothly. Beyond a certain point a certain node would basically be using all bandwidth to route packets back and forth, effectively becoming the bottleneck. I don't know if this could be alleviated for ultra-dense topologies though. Any good references, anyone?

Right, you mean that they should just sit down and watch as M$ will once again leverage their monopoly on the OS market and plaster MSN search all over the place on IE7, and the clueless 99% will just use that instead of yahoo or google.
Besides, if I read correctly, this applies only to IE users. Well, if someone is still using IE, I bet he will have to deal with far more many bad things than google toolbar. An extra search box won't make hell of difference.
Google is not a spyware company and apparently selling personal information is not their business model. Besides, they are making a shitload of money already, why would they want to try such risky stuff?

Because if you did, you would have noticed that ZFS and Dtrace are actually NOT available for linux and it will probably take considerable time to port such complex mechanisms to it.
One thing that's interesting about zfs is that it handles mirroring at the logical level and not at the physical level. In traditional approaches the filesystem module in the kernel sees a raid metadevice which is handled exactly like a physical device, eg. using the/dev/dsk/... and/dev/rdsk/... devices. The folks behind zfs figured that since we are talking about software based raid, there is no reason why the filesystem shouldn't know a little more about what's lies beneath. So, the mirroring for example is done at the block level. Each block has a checksum so it is possible to detect malfunctions between two mirrors of the same instance. Especially for filesystems that have relatively low usage, this method is megafast because it actually mirrors only the contents of the filesystem (a conventional raid would go ahead and mirror the entire physical disk bit by bit).
Basically you can run any application that runs on Solaris. You will also have to use the Sun N1 Grid Engine to make it run on many processors in parallel. As the article says, there are already companies that are using it to carry out certain tasks. Besides using the Grid Engine software, I suppose you could safely assume a POSIX environment.
