Fubari writes "I have questions for those of you who have written books: what writing tools have you found helpful? I want to start my book off right (so I'm pretty sure I don't want to write it in MS Word). What has and has not worked well for you? So far I have thought of needs like chapter/section management, easy references to figures (charts, diagrams, source code), version control (check in/check out parts like chapters, figures, etc.), and index generation. I would also welcome advice about what I don't know enough to ask about. Did you encounter any surprises that you wish you had known about back when you started out?"

gozunda writes "My company is an open source software vendor/developer. We maintain a popular open source project and keep ourselves afloat by producing commercial products derived from or extending the value of the core project. Over time we've seen our business model eroding as other open source projects produce free versions of the same extensions and utilities that are our bread and butter. Something that was worth $5K last year is suddenly worth $0 because the free version is just as good as the paid. This same cycle is obviously having an impact on pure-play commercial software vendors. Is open source ultimately a race to zero? In ten years will there be any cost associated with commodity (non-custom) software? If not, will there still be a 'software industry' as it exists today, or will software simply be a by-product of the operation of other industries? Is that a good thing or a bad thing? As a professional developer, do I need to fear this or feed it?"

An anonymous reader writes "I'm a Project Manager (hold the remarks) who recently decided that I want/need to get my dev skills more up-to-date, as more projects are looking for their PM's to be hands-on with the development. Looking around my house, I have quite the collection of older (read: real old — it's been a while) PCs — it's pretty much a PC graveyard. Nothing that would really help me set up a nice dev infrastructure for developing web/database apps. So, my question is as follows: Should I buy a number of cheaper PC's, or should I buy one monster machine and leverage (pick your favorite) virtual machine technology?"

An anonymous reader writes "The system generates warnings to riders and drivers of other vehicles by continuous exchange of positioning data from satellite GPS sources. This is particularly relevant as road users approach intersections, alerting them to other vehicles that are potentially on a collision course, allowing avoidance manoeuvres."

An anonymous reader writes "They've been on the drawing board for 40 years but the politicos have finally approved routes for the 500kph maglev trains to replace bullet trains." I wonder if they'll let me test out maglev rollerblades on the track.

CurtMonash writes "Parallel Efficiency is a simple metric that divides the actual work your parallel CPUs do by the sum of their total capacity. If you can get your parallel efficiency up, it's like getting free servers, free floor space, and some free power as well. eBay reports that it amazed even itself by increasing overall PE from 50% to 80% in about 6 months — across tens of thousands of servers. The secret sauce was data warehouse-based analytics. I.e., eBay instrumented its own network to do minute-by-minute status checks, then crunched the resulting data to find bottlenecks that needed removing. Obviously, savings are in the many millions of dollars. eBay has been offering some glimpses into its analytic efforts this year, and the PE savings are one of the most concrete examples they're offering to validate all this analytic cleverness."

I.M.O.G. was one of many readers to write with the news that "Advanced Micro Devices plans to announce Tuesday that it will split into two companies — one focused on designing microprocessors and the other on the costly business of manufacturing them — in a drastic effort to maintain its position as the only real rival to Intel. 'This is the biggest announcement in our history,' said AMD's chief executive, Dirk Meyer. 'This will make us a financially stronger company, both in the near term and in the long term, as a result of being out from the capital expense burden we have had to bear.'"

adamengst tips an article up on TidBITS that explores the persistent reluctance of many nerds to embrace fully new communications media such as IM and Twitter. In this thoughtful article Joe Kissell explores, from the inside, the mind of the introvert and how this personality style often struggles with new "always-on" media. The result is a sometimes exasperated incomprehension on the part of the more extroverted. Well worth a read.

Roland Piquepaille writes "UK researchers have recently used virtual reality to check if people had paranoid thoughts when using public transportation. Their VR tube ride experiment revealed that 40% of the participants experienced exaggerated fears about threats from others. Until now, researchers were relying on somewhat unreliable questionnaires to study paranoid thoughts which are often triggered by ambiguous events such as someone laughing behind their back. With the use of VR, psychiatrists and psychologists have a new tool which can reliably recreate social interactions. As the lead researcher said, VR 'is a uniquely powerful method to detect those liable to misinterpret other people.'."

Steven Noonan sends us to a page where he is collecting and updating results for various browsers on the newly released Acid 3 test. No browser yet scores 100 on this test. (We discussed Acid 3 when it came out.) He writes, "It's not surprising that Internet Explorer is losing to every other modern browser, but how did IE 5.5 beat IE 6.0 and 7.0?" All of the IE versions score below 20 on Acid 3.

Bridgestone, the company which debuted the "world's thinnest" sheet of two-color e-paper last year, has turned around and delivered a new version which is capable of displaying over four thousand colors. "In case that wasn't enough, the company is also touting what it calls the "world's largest full color e-paper that is A3 size, which is equivalent to a 21.4-inch screen." As you'd expect, the latter is expected to be used solely for advertising and could hit the market as early as next year, while the former technology is set to be commercially available in 2009."

Roland Piquepaille alerts us to research out of University College London in which virtual robots, trained to "see" as we do, were duped by optical illusions the same way humans are. Here's one of the illusions the software system fell for.

leffeman writes "An influential Brussels think tank is urging the European Commission to ban the bundling of operating systems with desktop and laptop computers. The Globalisation Institute's submission to the Commission says that bundling 'is not in the public interest' and that the dominance of Windows has 'slowed technical improvements and prevented new alternatives entering from the marketplace.' It says the Microsoft tax is a burden on EU businesses: the price of operating systems would be lower in a competitive market. This is the first time a major free-market think tank has published in favour of taking action against Microsoft's monopoly power."

owlgorithm writes "Apple's new store in Montreal has three parking meters on the street in front of it. The city is in the middle of a campaign to reduce downtown parking. In Apple's ever-conscientious attempt to improve design, they offered to reimburse the city for the parking meters and their revenue if the city would remove them. Answer: Non — because 'We've never done it before, so we can't.'"
