The most hotly contested issue raised by yesterday's post about the lithium-ion battery-powered Tesla roadster is only tangentially related to the car itself; instead, it's the energy generation and storage required for electric cars more generally to operate. Read on for the Backslash summary of the conversation, including several of the comments that defined the conversation.

mikemuch writes "In the last of his series of interviews with the stakeholders in Microsofts upcoming DirectX graphics API, Jason Cross speaks with the developers of Hellgate, Crysis, Flight Simulator X, and Age of Conan. They seem pretty stoked about the new technology's ability to get visual detail to a much higher level of realism, and to offload physics and AI to the CPU." From the article: "Without hardware, it is hard to evaluate which features will really make the biggest performance impact. The geometry shader looks pretty full of potential. So does the fact that you can write to buffers from any shader and then read them into another shader. Texture arrays look like they will make a big dent our batch count, which should lead to much better frame rates. At this point I feel like I'm looking at a shiny new toy through a shop window: I can't wait to get my hands on it and play with it, but I don't really know what it can do."

garzpacho writes "BusinessWeek has an interview with Gary Swisher, Mattel's Vice-President of Wheel Design, who talks about the challenges of designing new toys for today's tech-savvy kids. In addition to discussing 'the challenge of stewarding an old-school brand like HotWheels in our tech-driven age, the emerging technologies that will affect the toy industry, and Mattel's Web strategy,' he also talks about the effect that video games have had on toy design, and argues that exciting the imagination is the most important role that a toy can fill."

Michael J. Ross writes "Given the current popularity of the Web development language PHP, it makes sense that newcomers to the language have a large number of introductory and reference volumes from which to choose. But for the more advanced PHP programmer, there are far fewer titles that explain how to make the most of the language, by applying it to solve relatively substantial problems. One such book is PHP Hacks: Tips & Tools for Creating Dynamic Websites, by Jack D. Herrington. Read the rest of Michael's review.

An anonymous reader writes "According to DistroWatch, Damn Small Linux (DSL) is currently the most popular microLinux distribution. Linux.com (Also owned by VA) takes a look at why this might be the case, and how you can best take advantage of it. From the article: 'What began as a toy project to stuff the maximum software inside a 50MB ISO file has matured into a refined community project known for its speed and versatility. DSL includes the ultra-lightweight FluxBox window manager, two Web browsers, Slypheed email client and news reader, xpdf PDF viewer, XMMS with MPEG media file support for playing audio and video, BashBurn CD burner, XPaint image editing, VNCViewer and rdesktop to control Windows and Linux desktops remotely, and more. If they could do all this in 50 megs, imagine what they could do in more space. Last month the DSL developers released DSL-Not, a.k.a. DSL-N 0.1 RC1. It's 83.5MB of DSL coated with GTK sugar. Yummy!'"

menion writes to tell us that Cliff Wells has an editorial calling into focus some of the perceived problems with LAMP. Wells calls PHP and MySQL this generation's BASIC citing the Free Online Dictionary of Computing: "BASIC has become the leading cause of brain-damage in proto-hackers. This is another case (like Pascal) of the cascading lossage that happens when a language deliberately designed as an educational toy gets taken too seriously. A novice can write short BASIC programs (on the order of 10-20 lines) very easily; writing anything longer is (a) very painful, and (b) encourages bad habits that will make it harder to use more powerful languages well. This wouldn't be so bad if historical accidents hadn't made BASIC so common on low-end micros. As it is, it ruins thousands of potential wizards a year."

Nethemas the Great writes "The Universal Software Radio Peripheral or USRP created by Matt Ettus and Eric Blossom gives a new perspective on the radio spectrum, as in just about all of it from DC to 2.9Ghz. With the right software and daughterboards, their USRPs can capture FM, read GPS, decode HDTV, transmit over emergency bands, track peoples movement via their mobile phones, and much, much more. With prices starting at just $550 this new toy is accessible by most anyone."

galactic_grub writes "Researchers at Stanford have developed a robot that mimics the extraordinary climbing skills of the Gecko. These creatures can climb sheer surfaces thanks to the intermolecular forces exerted by millions of tiny hairs their feet, called setae. The robot, Stickybot, has polymer pads on its feed with synthetic setae. Check out the video of it climbing up a sheet of glass."

dada21 asks: "As an on-the-go journalist, IT consultant, entrepreneur and blogger, I find myself with way too much stuff. About 5 years ago I started to downsize and cut back to just 2 PCs total (small laptop and PVR desktop), 1 PDA, and 2 cell phones (main and backup). The laptop goes everywhere (doubling as a great GPS center in the vehicle for those long road trips), the PDA does, too. Traveling with all 4 electronic devices is a mess of cables: power/charger, USB, and the like. Everything is light and small but the bulk of all of it adds up. I currently use a Toy Machine messenger bag but it just doesn't work when you're trying to shove a file folder, pen/appointment selection and a day-timer in it. I'll spend the cash, even if it is really expensive, for the convenience, speed and quality for a jack-of-all-bags that can handle the jack-of-all-trades. What bag is the best solution?"

Seagull76 writes "Check out this 1 minute video with Greenpeace's underwater photo/videographer and deep sea toy specialist, Gavin Newman, aboard the Esperanza. After months of confronting whalers and pirates, some might envy the crew aboard the next leg of Defending Our Oceans who are heading to the beautiful Azores in the mid-Atlantic. For this leg of the expedition, the Esperanza has been equipped with state of the art monitoring equipment, including a remote operating vehicle (ROV) which can shoot video down to a depth of 300m, and a drop camera capable of reaching depths of 1,000 metres - giant squid territory! The ship will become part of the ongoing University of the Azores research program intended to establish greater scientific knowledge of the importance of deep-sea habitats and marine life. "

hmart writes "As seen on ZDNet's Open Source Blog MySQL is taking another step to defend from Oracle's recent acquisitions of InnoBase and Sleepycat. From the article: 'MySQL responds by getting Solid Information Technology, a proprietary database vendor, to take its solidDB Storage Engine for MySQL open source, under the GPL, starting in June.'"

Charles Fishman, senior writer for Fast Company magazine has recently published a book entitled The Man Who Said No To Wal-mart. It's an excellent book (Yes, I've read it) that talks about the intersection of making good stuff, the commodization of products, and the changing world that we work in; not exactly high tech, but tech nonetheless.

deman1985 asks: "As the owner of a small commercial and home integration company, I'm exposed to a wide variety of customers with differing tastes and needs. I'll get requests for anything from the ordinary audio distribution systems and full home theater systems, to downright bizarre requests like having bubble baths run automatically, when they walk in the door. However, the vast majority of customers I encounter are not technologically inclined and are more interested in simplicity rather than impressiveness. What would your ideal integrated home look like? What's the most unique feature you would like to see? If you had access to an unlimited budget, what would you spend money on to make your home stand out? Whole-house audio? Hidden video screens? Automatic locks? Do most people view home integration strictly as a toy for entertainment, or is the technology ready for prime time?"

Austin Milbarge asks: "Ever since the .NET framework came along a few years ago, Microsoft had promised VB developers that their language would finally be taken seriously. To be honest, I never understood why some non-VB developers thought of VB as a 'toy' language, but that is for another article. Anyways, Microsoft made good on their promise and transformed VB from an easy to learn language into an object oriented power house, with lots of OOP functionality thrown in. The old VB has been discontinued, and the new VB is no longer a simple language. With all the fancy changes, is VB still the great beginner's language it once was? Would you recommend it to a beginner over C#?"

deman1985 writes "As reported by UPI, Japan has unveiled their fastest supercomputer yet. Assembled from Hitachi and IBM components, the new system sports total performance around 59 trillion calculations per second and comes at a cool 5-year lease price of $30 million. Pictures of the beast can be found at Mainichi Daily News."

Nintendo DS News writes "Those lucky chaps at Lik Sang have done a hands-on review of the DS Lite, with masses of screenshots and comparisons between the new and old versions. Now, you can officially add whiter, cooler, prettier, sleeker, and overall better to your arsenal of superlatives when describing the Nintendo DS Lite in comparison with the first edition of the Nintendo DS. The new edition has for sure a fashionable look, and appears more modern than the previous model, which many compared to a 'cheap plastic toy from the 20th century' when it first came out.""

Slashback tonight brings some corrections, clarifications, and updates to previous Slashdot stories, including Google's reasoning behind rejecting the DoJ motion, more fodder for the Chinese censorship fire, one of last weeks "first computers" brought to life, the New York Times backs network neutrality, hard drive death dance tracks, Serenity enters the black, and the USPTO issues a final rejection in RIM patent case -- Read on for details.

toybuilder asks: "I have an idea for a neat consumer product that could benefit greatly from a really simple bare-die chip to reduce cost and size. I took a VLSI and chip design class back in college about 10 years ago, so I know how to design the circuit I want in CMOS. Now, I'm sure there must be fabs for older-generation designs (maybe in China/Taiwan) that I could have such a chip made -- I've seen bare chips in musical greeting cards and in tiny toy gadgets. How do I go about making my chip design into reality if I only want to make a fairly short run (a few *chips* during development, and maybe a 6" wafer's worth of the final design)?"

Snap E Tom writes "The Independent Online is reporting that Toy Story 3 has been scrapped. This is a strong clue that the Pixar guys are firmly in control at Disney. The ground-breaking films were being milked into almost as many movies as The Sims has expansion packs. John Lasseter, Pixar's creative head, was strongly against the idea of third and forth movies, while the old Disney regime pushed forward with it. Now with Pixar and Steve Jobs on the board, Lasseter has taken the necessary steps to prevent the franchise from being diluted."

Press the Buttons has an interesting and plausible sounding set of theories for the year ahead. From the article: "Sega will finally create an exceptional 3D Sonic the Hedgehog title when Sonic Team puts the entire extended cast (Tails, Knuckles, Amy, Cream, Blaze, Shadow, and the rest) back in the toy box for a while and focuses on what made the original Sonic games so much fun: blue skies and plenty of speed." Some of them may just be wishful thinking, though.
