The misconception this question enforces is stronger than that. 1 and 3 attempt compare the the measurement of physical properties while number 4 is a behavioural observation that can only be measured through correlation. Numbers 1 and 3 can be proven to be fact through measurement while number can only be a hypothesis(that can only be proven with a causation or disproven with a observation that states otherwise). From the TFA the purpose of the question is asses the student's ability to discern opinion/interpretation from a scientific observation. While number is undoubtedly a scientific observation, asserting number 4 is true after observation is still an opinion/interpretation, making it a poor choice to assert that student has a clear understanding of the difference between opinion and fact.
Peter Guttman's paper wasn't debunked, it was a victim of bitrot. Many of Guttman's sources and references were changed or updated as Guttman wrote the paper over a period of 2 years. Often the changes were a direct result of what Guttman wrote, other times other significant events outdated what he said(like the death of HD-DVD, which fundamentaly changed many of Guttman's arguments since HD-DVD was supposed to only be supported by Microsoft, until Blu-Ray became the the format left). Lastly many of those articles which "claimed" to debunk his paper used differing versions of the paper to create contradictions that did not exist. Or even spewed out more rhetoric in one sentence than they claimed Guttman had in his entire document,ie http://www.geekzone.co.nz/freitasm/3784 (Seriously, his first argument against Guttman is the length of his paper, like that has anything to do with it's credibility? OMMFFFGGG ITS OVER 26,000!!!!).
ruphus13 writes with a story about the open-source centric Willow Garage project (last mentioned on Slashdot early last year), which is making progress in creating helpful humanoid robots for household use. From the article: "PR2 is the mobile hardware design for Willow Garage robots, featuring stereo and laser sensors ... Senior citizens are a big part of the target audience that Willow Garage is aiming for. "All industrialized countries are facing aging populations that require assistance and care to remain independent into old age. By 2020 close to 20 percent of the US population will be over 65," the project leaders say. "These numbers are even higher in Western European and Asian countries." Willow Garage is aiming to produce several types of assistive robots." The PR2 robots are capable of performing critical tasks like cleaning rooms and bringing beer from a refrigerator."
Grayskull writes "The OS/2 and eComStation community are trying to get open source software ported to that platform by opening bounties and allowing people to chip in with prize money. Currently the most important open bounties are Java 6 port, Icon routines in OS/2, VirtualBox port, Extend multimedia and OpenWengo ports."
Raindeer writes to share his article about peering and transit between networks, which begins: "In 2005, AT&T CEO Ed Whitacre famously told BusinessWeek, 'What they [Google, Vonage, and others] would like to do is to use my pipes free. But I ain't going to let them do that...Why should they be allowed to use my pipes?' The story of how the Internet is structured economically is not so much a story about net neutrality, but rather it's a story about how ISPs actually do use AT&T's pipes for free, and about why AT&T actually wants them to do so. These inter-ISP sharing arrangements are known as 'peering' or 'transit,' and they are the two mechanisms that underlie the interconnection of networks that form the Internet. In this article, I'll take a look at the economics of peering and transit in order to give you a better sense of how traffic flows from point A to point B on the Internet, and how it does so mostly without problems, despite the fact that the Internet is a patchwork quilt of networks run by companies, schools, and governments."
figona brings news that India will be allowed to join the Nuclear Suppliers Group (NSG). A waiver was approved yesterday that provided an exception to the requirements that India sign the Nuclear Non-Proliferation Treaty and the Comprehensive Nuclear Test-Ban Treaty. This means India will be able to buy nuclear fuel from the world market and purchase reactors from the US, France, and Russia; something it has been unable to do since it began nuclear testing in 1974 (which inspired the creation of the NSG). The waiver does not include terms to cut off access if India resumes nuclear testing, but the US Congress drafted a letter stating their willingness to do so. Opponents of the waiver have called it a "non-proliferation disaster."
tonsofpcs writes "On Monday, September 8, Wilmington, NC will be the first television market (#135) to make the switch to DTV by shutting off their analog transmitters. This forum will be posting updates throughout the coming months to keep everyone updated on how the transition works so that we are all prepared come February 17, 2009. So far, it seems Wilmington will still be going ahead as planned, despite Tropical Storm Hanna's proximity."
Anti-Globalism writes "The major ISPs all tell a similar story: A mere 5 percent of their customers are using around 50 percent of the bandwidth, sometimes more, during peak hours. While these 'power users' are sharing three-gig movies and playing online games, poor granny is twiddling her thumbs waiting for Ancestry.com to load."
An anonymous reader writes "When Google is clouding the borderline between web and the desktop, a much, much smaller project is blurring the border between the Internet and the physical reality: the newly released Contiki operating system version 2.2.1. Contiki runs on networked wireless sensors that are used for anything from road tunnel monitoring for fire rescue operations to collecting vital statistics from ice hockey players. These sensors typically have as little as a few kilobytes of memory and a few milliwatts of power budget — a thousandth of the resources of a typical PC computer — yet Contiki provides them with full TCP/IP connectivity. Meanwhile, San Francisco is monitoring parking spaces with wireless technology."
rm writes "Internet search and mail provider Yandex, which many view to be Google's main competitor in Russia, has recently added an instant messaging capability to its mail notifier application Ya.Online. As it turns out, the IM service is based on the open XMPP protocol, with connectivity to all other public Jabber servers available from day one. MacOS X and GNU/Linux versions of the app were also released (complete with sources under the GPL) and are determined to be based on the Psi IM client. Yandex looks to be a firm believer in open-source, also running a mirror site for FOSS and actively promoting its branded version of Firefox. Here's hoping that its affair with XMPP will help eliminate ICQ's enormous foothold in Russia."
