It discusses suggested hardware and software designs and highlights the tradeoffs of each. It also describes important design pitfalls and best practices."

Michael Stroeck writes "Want that nifty scrolling on your portable but have an older one? No problem, Daniel Becker has written a free alternative driver for older PowerBooks and iBooks that works like a charm. It is based on Apple's AppleADBMouse-209.0.10 driver from Mac OS 10.3.7 that is available as part of the publicly released Darwin source code. As such, the driver is covered by the APSL (Apple Public Source License)."

News for nerds writes "The ISSCC 2005, the "Chip Olympics", is over and David T. Wang at Real World Technologies put a very objective review of the CELL processor (the slides for the briefing are also available), covering all the aspects disclosed at the conference. Besides the much touted 256 GFlops single-precision floating point performance the CELL processor has 25-30 GFlops in double-precision, which is useful enough for scientific computation. Linus seems interested in CELL, too."

An anonymous reader writes "Remember those iPod Satellite rumors last December? Mel Karmazin, the CEO of Sirius Satellite Radio, announced at the 2005 Media Summit that he had discussions with Steve Jobs about the possibility of putting Sirius' technology in future iPods. Steve's response? Not interested."

Roland Piquepaille writes "If you happen to be around Ohio this coming fall, don't miss an exhibit at the Mansfield Memorial Museum featuring the 7-foot-tall Elektro, the oldest robot in the U.S.. "Elektro is the only survivor of a group of eight robots created by Westinghouse in Mansfield between 1931 to 1940 for several hundred thousand dollars each," according to the article from the Plain Dealer, Cleveland. Back in 1939, Elektro was able to walk, talk, raise and lower his arms, turn his head and move his mouth as he spoke. It used a 78-rpm record player to simulate conversation and had a vocabulary of more than 700 words. It even appeared in a long-time forgotten movie, "Sex Kittens Go to College," also known as "The Beauty and the Robot." Primidi.com has an overview containing other details, references and pictures."

edg176 asks: "I am wondering about other people's experiences with getting Extended Warranty service. I bought a laptop at Microcenter. Got the top of the line extended warranty. Laptop died. I sent it in for service, and the outside repair place, MicroMedic, claims they can't fix it, and the actual warranty administrator is separate from the repair place -- way out in Florida! My warranty says I can get a full refund of my purchase price if the warranty people can't find me an equivalent laptop. They can't, because Microcenter no longer carries the sharp ultralight laptops. Dealing with warranty administrator people, Warrantech has been a nightmare. They won't let me speak to a manager and they keep jerking me around. So far, I've gotten them to agree to give me 1200 bucks store credit, which is still 500 bucks shy of the purchase price. Is it worth fighting them for the last 500 bucks? Does anyone have success stories or tips for this situation? Should I just take the 1200 and be happy I got that much?"

Demolition writes "You just knew that someone would get around to this, didn't you? In this how-to article from AppleTalk Australia, a step-by-step guide describes how to transplant a Mac mini into a micro-ATX case and a method to connect standard 3.5" hard drives to it (using do-it-yourself 2.5"-to-3.5" IDE adapters). Only some minor case modifications and some added cooling are needed to complete the project."

mcaycedo writes "This new projector is my top number 1 "must have" gadget. The reasons: price (US$699), size (fit in your hand), convenience (uses AC, batteries, card adaptor) and duration (lamp life:20000 hours). The cons: only SVGA (800x600), lumens (N/A)" There are tons of applications for a LED projector of this size, too: in cars, integrated into portable video players, information displays of all kinds ... and as resolution and brightness improve, even more will emerge.

When the PSP launches in the states, it will be accompanied by five online enabled titles, according to GamesIndustry.biz. Gamers will be able to challenge friends in short range ad-hoc games, but will also be able to compete against other PSP owners via an 'infrastructure' mode. From the article: "What this means, in effect, is that players will be able to connect to wireless hot spots - either at home or in wi-fi enabled public locations - and play games across the net in this manner."

Garak asks: "Webcams seem to be hit and miss for a combination of image quality, light sensitivity and price. Lately I've been mostly missing looking for a webcam to use on my mobile telerobot that I'm building for my thesis project. I require a webcam that will produce an acceptable picture under normal office lighting without breaking my shoe string budget. So Slashdot, what is the best value in a low cost, Linux compatible webcam?"

Hack Jandy writes "AnandTech has a very thorough, but not overly technical, article detailing CPU scaling over the last decade or so. The author goes into specific details on how CPUs have overcome limitations of die size, instruction size and power to design the next generation of chips. Part I, published today, talks specifically about the limitations of multiple cores and multiple threads on processors."

endersdouble writes "Ars Technica's Jon "Hannibal" Stokes, known for his many articles on CPU technology, has posted a new article on IBM's new Cell processor. This one is the first part of a series, and covers the processor's approach to caching and control logic. Good read."

Sparky the Service Center Dude writes "PCstats covers the most common ways to kill a PC in this "what not to do" guide. Everything from exploding capacitors, to cat hair, to dodgy components and overclocking account for users killing their own PC's. The most common PC killer? The Power Supply."

SpottedKuh asks: "Perhaps the days of sturdy laser printers are over, or perhaps it is just my bad luck. I've recently been the proud owner of two paperweights: First, an HP LaserJet 1100, which continually misfed papers and smeared toner. After selling that printer, I foolishly purchased a LaserJet 1012, not realizing just how poorly it played with my BSD systems. Naturally, I've learned my lesson about checking LinuxPrinting.org; but, more than that, I'm gun-shy about purchasing yet another printer to replace my current LaserJet. I look at one of my friends who has had a LaserJet 4P for probably around ten years, and it's still going strong. Are the days of such quality gone, or am I just looking in the wrong places?"

war3rd asks: "Years ago I used to offer tech support for friends and family (for free), and ended up doing it for everyone they and I knew. I cut it out because it was taking too much of my time, but I've been getting more and more requests lately due to everything from viruses, spam, spyware, as well as aging PC with Windows 98 and ME (oog!) on them still. I was thinking of saying OK to requests that are convenient, but I want to make it worth my while. So I ask, I'm sure that some of you out there must do this, what is the general going rate for basic user tech support (i.e. getting someone's home machine cleaned up and back to normal email & web browsing capability)?"

ricercar writes "So, what do you do when you and some friends are all getting iPod Shuffles? You make a RAID array out of them, of course! The original intent was to actually install OS X on the RAID and boot from that, but the OS X (Panther, 10.3.5) Installer wouldn't allow it."
