Surgical Robot Removes Calgary Woman's Brain Tumor 107

Raver32 points out an article in the Victoria Times Colonist about an interesting advance in robotic surgery: "Calgary doctors have made surgical history, using a robot to remove a brain tumor from a 21-year-old woman. Doctors used remote controls and an imaging screen, similar to a video game, to guide the two-armed robot through Paige Nickason's brain during the nine-hour surgery Monday. Surgical instruments acting as the hands of the robot — called NeuroArm — provided surgeons with the tools needed to successfully remove the egg-shaped tumor."

Understanding How CAPTCHA Is Broken 148

An anonymous reader writes "Websense Security Labs explains the spammer Anti-CAPTCHA operations and mass-mailing strategies. Apparently spammers are using combination of different tactics — proper email accounts, visual social engineering, and fast-flux — representing a strategy, explains their resident CAPTCHA expert. It is evident that spammers are working towards defeating anti-spam filters with their tactics."

Keeping Customer From Accessing My Database? 567

cyteen02 writes "We run a data processing and tracking system for a customer in the UK. We provide a simple Web site where the customer can display the tracking data held in our Oracle database. From these screens they can query based on a combination of 15 different data fields, so it's pretty flexible. We also provide a csv report overnight of the previous day's data processing, which they can load into their own SQL Server database and produce whatever reports they want. Occasionally they also want one-off specific detailed reports, so we write the SQL for that and send them the results in an Excel format spreadsheet. This all ticks along happily. However they have now asked for direct read-only access to our Oracle database, to be able to run ad-hoc queries without consulting us. As a DBA, my heart sinks at the thought of amateurs pawing through my database. Unfortunately, 'because you are stupid' is not considered a valid business reason to reject their request. So can any Slashdotters assist me in building my case to restrict access? Have you experienced a similar situation? Have you had to support this sort of end user access? How would you advice me to keep my customer away from my precious tables?"

What To Do With Old Laptops? 620

An anonymous reader writes "I've recently acquired a few old P2/P3 laptops. Most either work properly but are slow, or have various problems with power supplies and/or batteries. Attempting to sell them would probably earn less than the cost of shipping, so that's out of the question. I was hoping the Slashdot crowd could give me some ideas on what to do with these old computers. As somebody who already has ~10 computers lying around the house there is certainly no need for an additional computer to 'experiment' with, so I was hoping for some more creative suggestions."

Decent Book Clubs for Sci-Fi Fans? 406

willyhill writes "I'm a Sci-Fi and Fantasy book nut, but in the last few years I've found it more and more difficult to find the time to read. Contrary to what most people would think, I actually have a hard time finding books, rather than cuddling up with them. In reality, I don't have time to mess around at my local Barnes & Noble and browse books, and I find it dicey and expensive to do the same at Amazon or other online retailers. I was looking at a magazine the other day and I found an advert for the Science Fiction Book Club. While my experience with CD clubs and the like in the past has not been entirely positive, I was prepared to give it a shot given the fact that it would be less expensive than Amazon in the long run. The problem was that their selection is not exactly grand. Having read the Simmons Hyperion Cantos, for example, I was ready to give Ilium a go, but I could only find its sequel. How do other readers get their hands on Sci-Fi books? I tried Googling for book clubs and the like, but there's too much static out there, mostly caused by Oprah. Any suggestions would be appreciated!"

David Pogue Gushes Over the Chumby 134

stoolpigeon writes "IHT is running a David Pogue review of the Chumby. The Chumby is a small computer embedded in a soft case. The Chumby hardware and OS are open, and the review mentions that the device already has a large developer following, cranking out new widgets for owners. Pogue is obviously quite taken with the Chumby and gives a good introduction to a device that may be the inspiration for a new generation of hackers."
Education

Changing a School's Tech Disposal Policy? 218

An anonymous reader writes "I attend a state university where a new building has recently been put in, and a new budget put in place. They have decided to upgrade all the computer systems involved in the department, with a few slight exceptions. From my limited understanding, State policy is that we cannot just let things go, they have to be sent back to the state capital in order to take them off the books. Then they put them in the dumpster. I feel that this is a huge waste of useful machines (some are merely two years old), but I know not how to change this. Any suggestions, or does anyone know where Illinois dumps used tech?"

Replacing a Personal Rack-Mounted Server? 108

Starky writes "Many moons ago, I cobbled together a 1U rack mount from parts which has since been diligently serving up my homepage and web sites for family and friends. It's a truly "Mom and Pop Shop" setup, running on a rack secluded in a closet at home over a DSL line. At the time, I was able to piggyback my order on a large order placed by a company for which I was working, allowing me to get a substantial discount. Now, the time has come to consider a replacement. However, I no longer work at a company that orders chassis and chips by the dozen. I would like to get a rack-mountable chassis, but don't know where to go as a lowly individual consumer looking for a box with minimal specifications (1 processor, dual drives, and 1G RAM is about all I need) at a reasonable price. Any recommendation from Slashdotters who maintain their own rigs?"
Programming

Targeting PocketPCs With Mono? 90

That's What She Said writes "I am a long time Mac user and, as most people like me, I have some particular problems with Microsoft technologies. I need to develop applications for the PocketPC platform (Windows CE and Windows Mobile), some simple data collection applications for barcode-enabled portable data terminals. Every device manufacturer on the market offer SDK's for .NET, so I believe this is the way to go. I already tried Microsoft Visual Studio and I am having serious problems using the IDE. I simply don't understand it quite well. My programming experience comes from PHP and JavaScript, where all I needed was a simple text editor and to keep my work as tidy as I could. So, it seems that a full-fledged IDE is kind of scary to me or Visual Studio is not very good for beginners. I also want to keep my costs low and free alternatives are welcome." Read on for a bit more (below) on why TWSS is thinking about Mono as a development environment, and is seeking advice.

Building Websites with Joomla! 1.5 129

Michael J. Ross writes "Web developers are oftentimes under pressure to build attractive sites as quickly as possible, and thus they are increasingly making use of content management systems (CMSs), which offer most of the functionality typically needed in a site, such as user authentication, site-wide styling, and of course managing content contributed by site owners and users. Joomla is an extremely popular and heavily-used CMS, partly because it is one of the easiest to install, configure, and use as a starting point for a new site. But with all CMSs, Joomla's online documentation and forums can prove frustrating to the new developer. Books such as the recently published Building Websites with Joomla! 1.5 are intended to fill that gap." Keep reading for the rest of Michael's review.

Running Mac OS X On Standard PCs 623

ZDOne writes "ZDNet's reviews team have been tinkering with the various ways of running OS X on standard PCs. They found that with the right hardware components, a standard PC running Mac OS X Leopard is, at first sight, no different from a genuine Apple Mac. Special CPU extensions such as Intel VT-x provide support for software solutions like Parallels Desktop for Mac. Even Adobe Photoshop, which queries a Mac to verify its authenticity, runs fine on a standard PC thanks to EFI emulation. However the article points out that it's a pretty technical proposition to get OS X running on non-Apple hardware, beyond all but the most powerful power users. And then there is the legal question. Don't even think about trying to put OS X on your PC without first purchasing a legitimate copy of Mac OS Leopard."

Just How Effective is System Hardening? 154

SkiifGeek, pointing to our recent coverage of what the NSA went through to create SELINUX, wants to know just how effective system hardening is at preventing successful attack, and writes "When Jay Beale presented at DefCon 14, he quoted statistics (PDF link) that Bastille protected against every major threat targeting Red Hat 6, before the threats were known. With simple techniques available for the everyday user which can start them on the path towards system hardening, just how effective have you found system and network hardening to be? The NSA does have some excellent guides to help harden not only your OS but also your browser and network equipment."

Homemade VoIP Network Over Wi-Fi Routers 71

AnInkle writes "A blogger on The Tech Report details his research and testing of wireless voice communication options for remote mountainous villages in rural undeveloped areas. The home-built project involves open-source software, low-cost wireless routers, solar power, mesh networking, unlicensed radio frequencies and VoIP technology. Although his research began several months ago, he has concluded the first stage of testing and is preparing to move near one of the sites where he hopes to eventually install the final functional network. Anyone with experience or ideas on the subject is invited to offer input and advice."

"Understanding" Search Engine Enters Public Beta 192

religious freak sends word of the public beta of Powerset, a closely watched San Francisco startup that promises an "understanding engine" to revolutionize Web search. An article in SearchEngineLand points out that Powerset is reaching higher than for mere "natural language." Techcrunch has more details and analysis. For the beta, Powerset makes available all of Wikipedia to search — not all the Web. It's said that their understanding engine required a month to grok Wikipedia's 2.5M articles. The Web is currently at least 8,000 times as large.

A Walk Through the Hard Drive Recovery Process 238

Fields writes "It's well known that failed hard drives can be recovered, but few people actually use a recovery service because they're expensive and not always successful. Even fewer people ever get any insights into the process, as recovery companies are secretive about their methods and rarely reveal any more information that is necessary for billing. Geek.com has an article walking through a drive recovery handled by DriveSavers. The recovery team did not give away many secrets, but they did reveal a number of insights into the process. From the article, "'[M]y drive failed in about every way you can imagine. It had electro-mechanical failure resulting in severe media damage. Seagate considered it dead, but I didn't give up. It's actually pretty amazing that they were able to recover nearly all of the data. Of course, they had to do some rebuilding, but that's what you expect when you send it to the ER for hard drives.'"
