New Denial-of-Service Attack Is a Killer 341

ancientribe writes "Hacker RSnake blogs about a newly discovered and deadly denial-of-service attack that could well be the next big threat to the Internet as a whole. It goes after a broadband Internet connection and KOs machines on the other end such that they stay offline even after the attack is over. It spans various systems, too: the pair of Swedish researchers who found it have already contacted firewall, operating system, and Web-enabled device vendors whose products are vulnerable to this attack." Listen to the interview (MP3) — English starts a few minutes in — and you might find yourself convinced that we have a problem. The researchers claim that they have been able to take down every system with a TCP/IP stack that they have attempted; and they know of no fix or workaround.

There are many instances that we can see that in our attempts to transform energy into as much as possible usable work, we are always left with this "rest" amount of heat that we can not use anymore to generate even more work. Clear examples of these imperfect transformations are the coolant radiators in our cars and the cooling towers of many factories or power plants. In powerplants that use fossil fuels we can have an efficiency as poor as 50% or often even lower, meaning that only 50% of the energy enclosed in the fuel is converted into electrical power, by means of burning fuel, heat generation that leads to steam and steam that will drive then turbines and generators. 50% or less is that not a shame? Of course the question arises why that is the case?

The article mentions how the hardware was designed to solve the problems of robustness and operability in a very low-tech environment. It also covers the choice of OS and how the project leaders hope this will inspire children to take up computer programming."

Why Should We Expect A Rebuilt Internet To Work Any Better?->

From feed by techdirtfeed
Researchers associated with various universities and government-backed initiatives are exploring the idea that the existing internet should be scrapped and rebuilt from the ground up. Right off the bat, it seems pretty safe to say that our current internet infrastructure, which has billions upon billions invested into it, isn't going to be dismantled, and the researchers involved with these projects almost certainly realize that. Still, these studies are interesting from an academic perspective, and because they may influence future build-outs in some way. Those who are in favor of a clean start point to a number of different areas where the internet could be made better. Security is obviously a big one, and many of the different plans explore ways of building more security directly into the infrastructure of the internet. They also point to the rise of the mobile internet as something that the original internet researchers never conceived of, and thus didn't account for. As one professor puts it, in light of how much things have changed, "It's sort of a miracle that it continues to work well today." That sentiment, of course, would seem to betray the whole thing, since the internet does work well, despite it undergoing radical changes over the years.

The whole question sounds analogous to the debate between free markets and central planning. If you believe that complex systems need a high level of planning in order to work, it would seem miraculous that a free market system could remain relatively stable and efficient. But history has shown that, if anything, it's the centrally planned economies that more often go haywire. Perhaps the internet question should be turned around: why should we trust that a rebuilt internet, that was designed to fix the problems that we can imagine today, would be able to accommodate completely unforeseen issues that arise 40 years down the road?

Although I think the new application is mysteriously similar to http://www.grapheety.com. Noting the public/private, ability to add pictures, movies, etc.

Looks like the Geoblogging area is really starting to heat up."

Josh Fink writes "In honor of the 30th anniversary of the Star Wars saga, the United Stated Postal Service has announced it will be releasing various packages of Star Wars related stamps and promotions. Among these promotions include deploying mailboxes that look like R2D2, and 41 cent stamps. You can also vote for your favorite Star Wars stamp over the USPS by visiting www.uspsjedimaster.com. I don't know about all of you, but I am rather happy to see that Jar-jar Binks is NOT an option here."

LaughingCoder (914424) writes "According to an article on PC World at http://news.yahoo.com/s/pcworld/20070328/tc_pcworl d/130234&printer=1;_ylt=AqGYYKkLK4BaOrR8wAZBpFoRSL MF Google has been experiencing some outages with their online office suite Google Apps that have affected Premier (i.e. paying) customers. So far customers seem to be understanding, though slightly concerned that this may be a trend. At least one customer also expressed dismay at the level of support he received. It will be interesting to see how Google adapts to this new model where its users are paying customers who have higher expectations. When Gmail is unavailable to me (which has happened occasionally) I take it in stride since it's free. But if I was paying for it, and I bet my business on it, that would be a whole different ballgame and I would expect much better service."

KDE

+ - KDE 4.0 the holy grail of Desktops ?

Submitted by Anonymous Coward
An anonymous reader writes "With KDE 4.0 being expected some time this year, expectation runs high in the linux/unix users camp and the media read a lot between the lines of what the KDE developers say and do. In some ways KDE will provide a standard as to how a desktop should look and behave. This interesting article wonders whether KDE 4.0 will become the complete desktop which will meet the needs of a wide cross section of computer users. One of the common complaints that some Linux users have over KDE is that it is too cluttered. And by addressing this need without putting off the power users, the KDE developers could make it an all in one Desktop. Keep in mind that KDE 4.0 is based on Qt 4.0 and so can be easily ported to Windows and other OSes too which makes this thought doubly relevant."

If you think the system is working, ask someone who's waiting for a prompt.

Working...
