7 of the Best Free Linux Calculators 289

Posted by timothy from the open-in-tabs dept.
An anonymous reader writes "One of the basic utilities supplied with any operating system is a desktop calculator. These are often simple utilities that are perfectly adequate for basic use. They typically include trigonometric functions, logarithms, factorials, parentheses and a memory function. However, the calculators featured in this article are significantly more sophisticated with the ability to process difficult mathematical functions, to plot graphs in 2D and 3D, and much more. Occasionally, the calculator tool provided with an operating system did not engender any confidence. The classic example being the calculator shipped with Windows 3.1 which could not even reliably subtract two numbers. Rest assured, the calculators listed below are of precision quality."

15-Year-Old Student Discovers New Pulsar 103

Posted by ScuttleMonkey from the sky-isn't-the-limit dept.
For the second time in as many years, a student has made a discovery while participating in the Pulsar Search Collaboratory (PSC), a joint program between the National Radio Astronomy Observatory and West Virginia University designed to get students and teachers involved in analyzing data from the Robert C. Byrd Green Bank Telescope (GBT). This time it was high school sophomore Shay Bloxton, who discovered a brand new pulsar. "For Bloxton, the pulsar discovery may be only her first in a scientific career. 'Participating in the PSC has definitely encouraged me to pursue my dream of being an astrophysicist,' she said, adding that she hopes to attend West Virginia University to study astrophysics. Late last year, another West Virginia student, from South Harrison High School, Lucas Bolyard, discovered a pulsar-like object called a rotating radio transient. His discovery also came through participation in the PSC."

35 Articles of Impeachment Introduced Against Bush 1657

Posted by kdawson from the high-crimes-and-misdemeanors dept.
vsync64 writes "Last night, Congressman Dennis Kucinich (D-OH) spent 4 hours reading into the Congressional Record 35 articles of impeachment against George W. Bush. Interestingly, those articles (63-page PDF via Coral CDN) include not just complaints about signing statements and the war in Iraq, but also charges that the President "Sp[ied] on American Citizens, Without a Court-Ordered Warrant, in Violation of the Law and the Fourth Amendment,' 'Direct[ed] Telecommunications Companies to Create an Illegal and Unconstitutional Database of the Private Telephone Numbers and Emails of American Citizens,' and 'Tamper[ed] with Free and Fair Elections.' These are issues near and dear to the hearts of many here, so it's worth discussing. What little mainstream media coverage there is tends to be brief (USA Today, CBS News, UPI, AP, Reuters)." The (Democratic) House leadership has said that the idea of impeachment is "off the table." The Judiciary Committee has not acted on articles of impeachment against Vice President Cheney introduced by Kucinich a year ago.

New Opt-Out Clause Makes CAN-SPAM Worse 119

Posted by kdawson from the if-that-were-possible dept.
snydeq writes "Three years of mulling, and the FTC has made the CAN-SPAM Act worse, writes Gripe Line's Ed Foster. Chief among the offenses in the FTC's updated rules is an even worse approach to opt-out procedures. In the future, in scenarios where multiple marketers use a single email message to spam you, 'only one of the senders — the one in the From: field — need be designated the official sender who is responsible for honoring opt-outs,' Foster writes. Translation? 'Other "marketers" who used that spam message, not to mention the spamming service that actually provided the email address list, don't need to honor opt-outs. So try as you might to get yourself off a list, the real spammer can just keep changing the designated sender in the From: field and legally keep on spamming you.' The irony of the CAN-SPAM moniker gets thicker."

Relics of Science History For Sale At Christie's 142

Posted by timothy from the shroud-of-einstein-doesn't-have-the-same-ring dept.
circletimessquare writes "Dennis Overbye at the New York Times has some ruminations on some of the historical totems of science going up for auction at Christie's next week. There is the 1543 copy of 'De Revolutionibus Orbium Coelestium' by Copernicus, which you can have for $900,000 to $1.2 million. If you have some cash left over, maybe you can pick up an original work by Galileo, Darwin, Descartes, Newton, Freud, Kepler, Tycho Brahe, or Malthus. And then there is the 1878 copy of the world's first phone book: 'a shock of recognition — that people were already talking on the phone a year before Einstein was born. In fact, just two years later Einstein's father went into the nascent business himself. Einstein grew up among the rudiments of phones and other electrical devices like magnets and coils, from which he drew part of the inspiration for relativity. It would not be until 1897, after people had already made fortunes exploiting electricity, that the English scientist J. J. Thomson discovered what it actually was ...'"

Study Hints At Time Before Big Bang 408

Posted by kdawson from the other-side-of-the-looking-glass dept.
canadian_right informs us that scientists from Caltech have found hints of a time before the Big Bang while studying the cosmic microwave background. Not only does the study hint at something pre-existing our universe, the researchers also postulate that everything we see was created as a bubble pinched off from a previously existing universe. This conjecture turns out to shed light on the mystery of the arrow of time. Quoting the BBC's account: "Their model suggests that new universes could be created spontaneously from apparently empty space. From inside the parent universe, the event would be surprisingly unspectacular. Describing the team's work at a meeting of the American Astronomical Society (AAS) in St Louis, Missouri, co-author Professor Sean Carroll explained that 'a universe could form inside this room and we'd never know.'"

Red Hat Vows To Stand Up To Patent Intimidation 168

Posted by Zonk from the stiff-upper-lip dept.
mrcgran writes "Eweek is reporting on Red Hat's assurances that can continue to deploy Linux without fear of legal retribution from Microsoft. This, despite the increasingly vocal threats emanating from Redmond. 'In a scathing response to Ballmer's remarks, Red Hat's IP team said the reality is that the community development approach of free and open-source code represents a healthy development paradigm, which, when viewed from the perspective of pending lawsuits related to intellectual property, is at least as safe as proprietary software. "We are also aware of no patent lawsuit against Linux. Ever. Anywhere," the team said in a blog posting.'"

Submission + - Intel's future processors

Submitted by madison
madison writes: Researchers at Intel are working on ways to mask the intricate functionality of massive multicore chips to make it easier for computer makers and software developers to adapt to them, said Jerry Bautista, co-director of Intel's Tera-scale Computing Research Program. These multicore chips, he added, will also likely contain both x86 processing cores, as well as other types of cores. A 64-core chip, for instance, might contain 42 x86 cores, 18 accelerators and four embedded graphics cores.

In another development Intel has updated its Itanium roadmap to include a new chip dubbed "Kittson" which will follow the release of Poulson- which will be based on a new microarchitecture that provides higher levels of parallelism. "There will be four or more cores, multithreading enhancements, and we'll also introduce more instructions to take advantage of parallelism, especially in virtualization." said William Wu, regional marketing manager for server platforms at Intel Asia-Pacific.

Feed Are Social Network Private Messages More Private Than Email Under The Law? (techdirt.com)

From feed by techdirtfeed
It's always interesting to see how courts deal with changing technology. For example, it's pretty common for courts to order emails to be handed over in certain lawsuits as part of the discovery process. However, for many younger people, email has taken a backseat to more popular private messaging features on social networks like MySpace and Facebook. In a recent court case, one side requested access to the private messages in the same manner that they would normally request access to email. However, both MySpace and Facebook have privacy policies saying they won't share the info (though, both say that they will under a court order). In this case, the court decided that it was too early to hand over access to such private messages, saying that the defendant's lawyer needed to first use other routes to try to find the information he was looking for before the court would blindly hand over access to social network private messages. It's likely that this type of request will start to become more popular in court cases -- and it may be difficult for judges to believe that social networking private messages are effectively any different than email.
