Yes.

Good news: rsync works as root.
Bad news: After numerous reboots and combinations of user passwords, I'm still only able to rsync using the root account. Next step will be to dig through the user permissions in the device (ssh as root and play with combinations of groups and maybe the settings for ssh in the
Journal Journal: Enabling rsync on Iomega StorCenter 1
Recently bought an Iomega StorCenter ix2-200 for our small office. I've got three Linux machines that I want to synchronize to this device using rsync.
I set the machine up with security, passwords, and so on. Using the web control panel, enabled that "rsync" option (on "Settings|Network Services" page), but that actually didn't do anything -- I get the following:
Comment Engineering programming - SQL and PHP (Score 1) 434
I do process engineering calculations in some pretty big applications. Many of them are web-based since I'm too lazy to program user interfaces. Side bonus is two of us can work on the application at the same time if it is web-based.
The single most useful thing I can recommend for engineering & science students is SQL. I can't tell you how many people I've seen using spreadsheets for a completely inappropriate application because they don't know how a proper database works.
But SQL doesn't do much by itself - I use PHP to interface with it. PHP has its problems, but it is simple, forgiving, and widespread.

Comment Re:Applied maths? (Score 1) 515
Agree. I am an engineer and find myself frequently unable to solve a problem because my pure math skills are not up to the task.
The most useful one is statistics (ok, mathematics profs don't consider statistics a math, but meh). Next most useful is classical geometry (which they don't teach any more - been replaced by trigonometry). Most of the really advanced maths engineers get taught (differential equations, even most calculus) are not useful to most of the daily problems faced by engineers.
The best math course I ever took in first-year engineering was linear (matrix) algebra. Awesome branch of math and useful for computer programming as well (arrays).

I frequently click the ads of companies and organizations I disagree with (eg. PETA, soft) to bleed money from the advertiser to the website. Except I open the ad in a background tab on Firefox, then close the tab without viewing it.
This is the same thing as send back those pre-paid envelopes for 'business reply' to groups I dislike and leaving the envelope empty.
Long-Term Storage of Moderately Large Datasets? 411
hawkeyeMI writes "I have a small scientific services company, and we end up generating fairly large datasets (2-3 TB) for each customer. We don't have to ship all of that, but we do need to keep some compressed archives. The best I can come up with right now is to buy some large hard drives, use software RAID in linux to make a RAID5 set out of them, and store them in a safe deposit box. I feel like there must be a better way for a small business, but despite some research into Blu-ray, I've not been able to find a good, cost-effective alternative. A tape library would be impractical at the present time. What do you recommend?"
Space Photos Taken From Shed Stun Astronomers 149
krou writes "Amateur astronomer Peter Shah has stunned astronomers around the world with amazing photos of the universe taken from his garden shed. Shah spent £20,000 on the equipment, hooking up a telescope in his shed to his home computer, and the results are being compared to images taken by the Hubble Space Telescope. 'Most men like to putter about in their garden shed,' said Shah, 'but mine is a bit more high tech than most. I have fitted it with a sliding roof so I can sit in comfort and look at the heavens. I have a very modest set up, but it just goes to show that a window to the universe is there for all of us – even with the smallest budgets. I had to be patient and take the images over a period of several months because the skies in Britain are often clouded over and you need clear conditions.' His images include the Monkey's head nebula, M33 Pinwheel Galaxy, Andromeda Galaxy and the Flaming Star Nebula, and are being put together for a book."
Own Your Own Fighter Jet 222

The End Of Gravity As a Fundamental Force 650
An anonymous reader writes "At a symposium at the Dutch Spinoza-instituut on 8 December, 2009, string theorist Erik Verlinde introduced a theory that derives Newton's classical mechanics. In his theory, gravity exists because of a difference in concentration of information in the empty space between two masses and its surroundings. He does not consider gravity as fundamental, but as an emergent phenomenon that arises from a deeper microscopic reality. A relativistic extension of his argument leads directly to Einstein's equations." Here are two blog entries discussing Verlinde's proposal in somewhat more accessible terms.
Update: 01/12 04:48 GMT by KD : Dr. Verlinde has put up a blog post explaining in simpler terms the logic of the gravity from entropy paper. He introduces it with: "Because the logic of the paper is being misrepresented in some reports, I add here some clarifications."

Mars Images Reveal Evidence of Ancient Lakes 128
Matt_dk writes "Spectacular satellite images suggest that Mars was warm enough to sustain lakes three billion years ago, a period that was previously thought to be too cold and arid to sustain water on the surface, according to research published today in the journal Geology. Earlier research had suggested that Mars had a warm and wet early history but that between 4 billion and 3.8 billion years ago, before the Hesperian Epoch, the planet lost most of its atmosphere and became cold and dry. In the new study, the researchers analysed detailed images from NASA’s Mars Reconnaissance Orbiter, which is currently circling the red planet, and concluded that there were later episodes where Mars experienced warm and wet periods."
Aussie Scientists Find Coconut-Carrying Octopus 205
An anonymous reader writes with this excerpt from an AP report: "Australian scientists have discovered an octopus in Indonesia that collects coconut shells for shelter — unusually sophisticated behavior that the researchers believe is the first evidence of tool use in an invertebrate animal. The scientists filmed the veined octopus, Amphioctopus marginatus, selecting halved coconut shells from the sea floor, emptying them out, carrying them under their bodies up to 65 feet (20 meters), and assembling two shells together to make a spherical hiding spot. ... 'I was gobsmacked,' said Finn, a research biologist at the museum who specializes in cephalopods. 'I mean, I've seen a lot of octopuses hiding in shells, but I've never seen one that grabs it up and jogs across the sea floor. I was trying hard not to laugh.'"
Herschel Spectroscopy of Future Supernova 21
davecl writes "ESA's Herschel Space Telescope has released its first spectroscopic results. These include observations of VYCMa, a star 50 times as massive as the sun and soon to become a supernova, as well as a nearby galaxy, more distant colliding starburst galaxies and a comet in our own solar system. The spectra show more lines than have ever been seen in these objects in the far-infrared and will allow astronomers to work out the detailed chemistry and physics behind star and planet formation as well as the last stages of stellar evolution before VYCMa's eventual collapse into a supernova. More coverage is available at the Herschel Mission Blog, which I run."
Students Take Pictures From Space On $150 Budget 215
An anonymous reader writes "Two MIT students have successfully photographed the earth from space on a strikingly low budget of $148. Perhaps more significantly, they managed to accomplish this feat using components available off-the-shelf to the average layperson, opening the door for a new generation of amateur space enthusiasts. The pair plan to launch again soon and hope that their achievements will inspire teachers and students to pursue similar endeavors."
