*BSD is dying (Score:1)
Let's keep to the facts and look at the numbers.
OpenBSD leader Theo states that there are 7000 users of OpenBSD. How many users of NetBSD are there? Let's see. The number of OpenBSD versus NetBSD posts on Usenet is roughly in ratio of 5 to 1. Therefore there are about 7000/5 = 1400 NetBSD users. BSD/OS posts on Usenet are about half of the volume of NetBSD posts. Therefore there are about 700 users of BSD/OS. A recent article put FreeBSD at about 80 percent of the *BSD market. Therefore there are (7000+1400+700)*4 = 36400 FreeBSD users. This is consistent with the number of FreeBSD Usenet posts.
Due to the troubles of Walnut Creek, abysmal sales and so on, FreeBSD went out of business and was taken over by BSDI who sell another troubled OS. Now BSDI is also dead, its corpse turned over to another charnel house.
All major surveys show that *BSD has steadily declined in market share. *BSD is very sick and its long term survival prospects are very dim. If *BSD is to survive at all it will be among OS hobbyists, dabblers, and dilettantes. *BSD continues to decay. Nothing short of a miracle could save it at this point in time. For all practical purposes, *BSD is dead.

Some of the technologies used in this are also applicable to any low bandwidth high latency connection. IP header compression is a prime example of this. Most people on Slashdot probably havn't considered the consequences of using IP over a link with a bandwidth measured in the low double digit bytes per second where return traffic may take several minutes to reach you, but people working with secure communications or low power long distance wireless links sure have.
One final thing I'm sure will interest many Slashdotters, the SCPS gateway runs on FreeBSD (and many other platforms as well, but it was developed under FreeBSD).

Barriers to exploration (Score:1)
I finally understand why planet-wide exploration and colonization didn't really happen until Columbus. It must have been as fantastically expensive to cross an ocean then as it is to go to the moon or Mars now. Modern society is facing similar problems to Columbus: Why bother with the expense and danger of exploration & colonization when there is plenty to explore, research, mine, trade, etc. locally? What is really funny is that Columbus was able to get money for his expeditions in the same way NASA has: National ego. Spain had the English and Portugese to one-up, and the American's had the Soviets and the Chinese. I guess it just goes to show that not much changes, even in 500 years.

Greenland was settled by Norse explorers in the Middle Ages (and of course earlier by various peoples from North America); the colony was cut off from Europe sometime in the late 1300s or early 1400s, and perished sometime in the 15th or 16th Century. The Portuguese were busy sailing down the coast of Africa and around into the Indian Ocean. They weren't going to Greenland!
(Now, had Columbus somehow ended up in Iceland, and somehow gotten someone to translate a few of the old pagan sagas, he might have deduced the existence of lands to the west. Lands with not much to offer except grapes and hostile natives, according to the sagas, so Columbus probably wouldn't have been too interested anyway.)
The reason Columbus insisted that China was close enough to be reached by contemporary sailing ships from Spain was because he simply got the distance wrong. As you mention, the radius of the earth had been accurately measured over a thousand years earlier, by the Alexandrian Greek Eratosthenes. He gave the earth's circumference in stadia, a common unit in Hellenistic times.
So how long is a "stadium"? Ah, there's the problem -- in late 15th Century Europe, they had recovered Eratosthenes' work, but not enough of the context, so they didn't really know. Columbus argued for a small value, which made the earth small and China not too far away. His academic opponents argued for a larger value, which would mean China was too far away. And, as we all know, Columbus was... well, wrong. His ships would have run out of food and water well before reaching China, but they luckily ran into the Americas on the way.

The core developers of the internet probably have very little trouble getting full-time connections to the internet. Until the advent of DSL and cable though, many of us were stuck with dialup connections. I've longed for an SMTP-like protocol that my programs could use to talk to each other when their connection was down.
Even for "permanent" connections, this protocol is useful. Connections go down from time to time, so apps that absolutely need 100% reliability need to build in code to wait and retransmit later when the link is back up. Instead of having each app implement this in a different way, a standard store-and-forward tcp protocol could have been designed.

I don't even think that it is that far out. Wireless, disconnected devices, and packet radio connected subnets are all examples of systems that need a similar solution. I for one would quite like to see an HTTP implementation that is hosted on a message oriented transport protocol instead of TCP. E-mail would also translate well of course, as would usenet.
HTTP would have to be modified slightly to bundle subrequests automatically (a wget protocol?) and I haven't yet read far enough to see how the draft RFC proposes establishing a route between the source and destination. If those routes change very rapidly (as for example might be true over packet radio) I can imagine some difficulty in finding a path to the destination.
Re:Come on, Give them a lottle credit... (Score:3)
Yeah, I remember reading about IP/SMTP back when it came out. The ping times are supposed to be 30s or so, but with the IT infrastructure at my company I think they would end up being closer to five minutes or more.
In any case TCP isn't going to run well over that kind of latency, you'll just fill up the pipe with retransmit requests until the TCP connection times out.
To really make use of this kind of application you need some protocols that aren't oriented toward interactive latency. IP datagrams over avian carrier are all well and good, but at an hour per packet they had damned well better be carrying complete messages.
I could see the Palm Pilot application synchronization being done over non-interactive protocols. Store and forward messaging would work fine, and of course the web would be okay if a bit slow (over SMTP.)
So there are plenty of potential uses, the question is really whether those uses will become prevalent, or the latencies of handheld wireless devices will drop to where they are no longer needed.

Secondly, the Portuguese were active in parts of the Northern Atlantic in the 1400's, and increasing rapidly thereafter, particularly due to several expeditions searching for a northwest passage. Now, why they would search for that in the shores around Greenland, if they at the time did not have knowledge that America likely stretched far north, is an interesting question.
There are claims concerning Columbus visiting both Greenland and Iceland.
Some claims about Portuguese activity in the North Atlantic can be found here: a message referring to claims about Portuguese slave traders [hum.gu.se], an article (in Norwegian, unfortunately) referring to theories about Columbus reaching Labrador in 1477, with subsequent Portuguese activity in the Northern regions as a result [dagbladet.no], a claim that Vatican records tells of a slaving raid in 1418, and information about a possible Portuguese expedition to Greenland around 1479, an article about possible contact between Columbus and Vikings on Iceland, based on memoirs written down by his son [usnews.com].
Much of this is of dubious quality, though, and I'm certainly not judging their quality, but it is an interesting theory whether correct or not.
While brining up more or less weird theories, though, there's a few people that have presented a theory that Columbus was originally Scandinavian, member of an important family with roots in royalty throughout Europe.
Decide for yourself whether to laugh at a funny story, or believe there's something in it. But either way, history from that far back isn't always as straightforward as people tend to think - there are very few parts of history from that time period that is comprehensively documented in trustworthy sources.
