Kids, don't try this at home On the contrary, if you want to try this, do it at home... that way you won't find yourself floating at 16,000 feet unless you have an exceptionally weak roof.
How long before spammers started including www.slashdot.org, www.yourwebsite.org or whatever in their Spam. By the time the numbers got big enough to hurt the Spammers, they'd also be big enough to do damage to other people.
Spammers are vile and disgusting, but for the most part they are not stupid. They're highly agile, and know how to get around and explot systms like these.
You just need to know the address of *any* node in the network. You cache every node you've seen and hopefully at least one of them is up. You can't magically connect to the network with no foreknowledge, but it is decentralized in that all nodes are equal. There is no node/set of nodes that *must* be up for the network to function. Anybody can maintain a list of nodes they've seen and you can just try those and just need for one single node to still be valid.
In practice, it usually makes sense to have some level of centralization, where there are some well-known nodes that are semi-permanently up, but if things got to the point where they were forced to shut down, you could still get on the network by finding just one single node by *any* means you can, such as word-of-mouth.
Assume every node connects to some number of "neighbors", and you can query a node and request its list of neighbors. You can then find a fairly random node from a N node network by starting from any node, picking one of its neighbors at random, then picking one of its neighbors at random and so forth about log N times. Then, assuming the network connections were random to start with, the node you pick has a uniform probability of being any of the N nodes in the network. You pick this node as your neighbor. Repeat this till you have enough neighbors (20-30 is usually a good number). The queries for finding different neighbors can, of course, be done in parallel, so the whole process shouldn't take more than a minute or so.

You are amazingly naive. Yes, the NOAA can't change the weather, but if there's a big hurricane headed my way, I'd like to know about it so I can board up my house and either prepare to weather the storm, or if its severe enough, leave for safer ground. If I'm a fisherman or own a sailboat, I'd like to know when a storm is going to hit in the evening, so I don't sail out to sea in the morning. If I'm a pilot I'd like to know if my destination is going to get 2 feet of snow and make it impossible for me to land.
A category 4 storm is definitely something to be very afraid of. I blizzard is also something to be very afraid of if you're going to be outside and unprotected. Maybe they don't value human life very much in Latvia (assuming that is where you are from), but here in the US we don't take too kindly to avoidable deaths. (Unless, of course such avoidance would come in the way of corporate profits, but that's a whole different story)
I think this post is a poster child for everything that's wrong with slashdot. A guy gives a knee-jerk response about how evil technology X is, disputes what the article explicitly says without a shred of evidence or even well reasoned... heck even POORLY reasoned logic, and gets moderated "Insightful"?!

If true, how is it a threat to Cisco? They can happily take whatever bits and pieces of the XORP code they like and use it in their own products and always stay ahead.
1. Most snail-mail junk mail, while useless and annoying, is legitimate. i.e. the coupons will really get you the said discount, the catalogs are from real stores. If not, their physical location is known and they can be brought up on charges under existing mail-fraud laws.
2. Snail-mail spammers bear the entire cost of printing, mailing and delivering their stuff. With e-mail, the ISPs and recipients must bear the cost of the wasted bandwidth (to say nothing of the cost to victims who are parts of botnets)
Tell me about it! Also, I can't believe the time it took for just bash to load on that old ENIAC (running a x86 emulator). Clealy we need a hand crafted assembly OS with and interfact approximating "?", to ensure that it runs blazingly fast on every computer ever built
I'm not sure if you're trolling or just badly informed and incapable of understanding my posts. I'm going to give you the benefit of the doubt and assume you're not a troll.
1. Where does it say there there's no public domain after this point? Right now copyrights are "limited" to max (95 years after creation, year of death of last author+75 years)
2. Where did I say that putting stuff into the public domain is bad? I just said that just because you're not selling something doesn't mean should automatically come into the public domain.
If that were the case, Linux would be released into the public domain automatically since Linus Torvalds isn't profiting by selling it.
If you own the original material, it is your right to do anything with it that you want with it, including locking it up in a vault. Just because you're not selling it and not profiting from it doesn't mean it automatically gets released into the public domain.
I agree that copyrights shouldn't be allowed to persist as long as they are, but that is quite irrelevant to my comment.
If a company is not selling the product anymore, then how can copying a program deny them a sale? They're not making any money off of it. One could conceivably argue that it deprives them of competitive advantage. Eg. even though Microsoft no longer sells Win98 having Win98 available freely would hurt WinXP sales. Even if one person chose that Win98 is good enough and they don't need WinXP, that is lost revenue.
That said, all science is good science While true, the real question if whether that $1-2b could be spent on doing better science. Of course, merely because $2b can purchase a new telescope doesn't mean it isn't worthwhile to do a robotic mission if the science and engineering aspects involved are new and exciting enough, or if the robotic equipment could be used for future time/money saving work.
If its going to be a relatively routine job, then maybe its better to say a fond farewell to Hubble and build a new space telescope drawing on all the lessons learnt from Hubble's shortcomings.
You're gonna make a full Unix-like operating system and desktop environment? Maybe you could make a little toy system. Do you know how many MILLIONS of man hours would go into that?
You could try and target that old 386 box in the basement, but don't even bother with SMPs, clusters and large high end machines!
She noticed that the way the tollbooths (both entering and leaving the highway) responded differently when she had the pass in the bag than when there was no pass in the car.
Different how? All I've ever seen tollbooths do is say "EZ Pass. $x.xx. OK" and then raise the barrier. Did start to raise the barrier, hesitate, bring it back down and then say "Um. yeah. no ezpass. wink wink"?
The core routers are nowhere close to being overloaded. They are rarely running at more than 50% or so capacity. Congestion is almost always at the edges. Individual ASes might me underprovisioned (or rather not overprovisioned enough) but the core of the Internet itself (i.e. the inter-AS backbones, the peering points etc) have plenty of bandwidth.

Because its illegal, just generates more useless Internet traffic, and may hurt innocent people given that many spammers use zombie machines

You'd better hope the "stupid agency" is doing its job the next time you board an aircraft, or have a hurricane/tornado/major snowstorm hit your area.

Stop being such a looser. Its not really that important.
