Yes it really does work that way. Any PCI device in your system can read/write to any location it can address. If the device only has 32-bit PCI then it is limited to the lower 4G of memory space, if it is 64-bit PCI then it can go anywhere.

There is an IOMMU ( but I am not very familiar with it. More modern machines than I was working with would probably implement this for protection from the device.


Submission + - Getting Students to Think at Internet Scale (

Hugh Pickens writes: "The NY Times reports that researchers and workers in fields as diverse as bio-technology, astronomy and computer science will soon find themselves overwhelmed with information so the next generation of computer scientists has to learn think in terms of internet scale of petabytes of data. For the most part, university students have used rather modest computing systems to support their studies but these machines fail to churn through enough data to really challenge and train a young mind meant to ponder the mega-scale problems of tomorrow. “If they imprint on these small systems, that becomes their frame of reference and what they’re always thinking about,” said Jim Spohrer, a director at IBM.’s Almaden Research Center. This year, the National Science Foundation funded 14 universities that want to teach their students how to grapple with big data questions and students are beginning to work with data sets like the Large Synoptic Survey Telescope, the largest public data set in the world, which takes detailed images of larger chunks of the sky and produces about 30 terabytes of data each night. “Science these days has basically turned into a data-management problem,” says Jimmy Lin, an associate professor at the University of Maryland."

Submission + - Is working for the gambling industry a black mark? 5

An anonymous reader writes: I'm a recent university graduate. I and have been offered a software developer position in a company that supplies software to the gambling and betting industry. At first I was very excited about the opportunity. However, a few of my friends have told me that working for the gambling industry will put a permanent black mark on my career as a software developer. I don't know that many people in the industry with experience in hiring. Google has not helped in any way. And everybody else I ask doesn't know. So I'm asking slashdot. In your experience is this true? When you hire developers, is the fact that they worked for a gambling company a big turn off? Also, I'm currently in the UK, but would like the freedom of working in US or somewhere else later on in life. So experience from anywhere in the world is welcome.

Submission + - Novel gadgets to rival traditional paperbacks (

An anonymous reader writes: Leave it to steampunks to come up with a 21st century replacement for the old paperbacks and "penny dreadfuls." They have A-list authors and are cheap enough (US$1.99) to buy for reading on your lunch break. The stories are old-fashioned in style but the delivery mechanism is all digital and online (for Kindle, iPhone, desktop you name it). Yes and DRM free!

Submission + - Cheating is widespread among graduate students

sas-dot writes: Thirty-four first-year business graduate students at Duke University cheated on a take-home final exam, a judicial board has found, in what officials called the most widespread cheating episode in the business school's history. Nine of the students face expulsion, according to the ruling, which was distributed within the business school on Friday. Fifteen students were suspended for a year and given a failing grade in the course; nine were given a failing grade in the course, and one got a failing grade on the exam. Four students accused of cheating were exonerated. National surveys have suggested that cheating is widespread among graduate students. In a survey released last September by a Rutgers University professor, 56 percent of business graduate students admitted having cheated, compared with 54 percent in engineering, 48 percent in education and 45 percent in law school. More than 5,300 students at 54 universities were surveyed from 2002 to 2004.
The Matrix

Submission + - Can you prove we are not in The Matrix?

Herby Sagues writes: "The theories that claim that we are not living in the real world but we live in a simulated world run on computers instead, in which we are either part of the simulation (like in "13th floor") or just plugged to it (like in The Matrix) are not taken seriously by most, but have not be disproven either. Can you propose an experiment that would prove (or disprove) we run in the real world? Playing with intractable problems, discrete time or other techniques might yield results, though you must consider the possibility of nontraditional (i.e. not temporal/spatial) simulations."
