New Linux-based PDA due September 182

Posted by CmdrTaco from the and-it-fits-in-the-palm-of-your-hand dept.
Bill Kendrick writes "LinuxDevices.com has a preview of a new Linux-based PDA due out next month. Some of you might recognize the form-factor; it's from Softfield, the folks who ended up with the rights to the first commercial Linux-based PDA, the black-and-white, MIPs-based Agenda VR3. Softfield's new model, the MX-7, sports a 200MHz CPU, full-color 240x320 display, 32MB Flash and 64MB RAM, an SD card slot, and Trolltech's Qtopia environment. All for $299 USD."

Networking the Redwoods 175

Posted by michael from the got-root dept.
linuxwrangler writes "SF Gate is reporting that ecology researchers are outfitting a grove of trees with tiny "micromote" sensors to monitor the light, humidity and other conditions as the trees grow. The sensors, running the open-source Tiny OS, form and maintain their own network. This test of the "Smart Dust" concept (mentioned on /. earlier) only uses 50 sensors but scientists hope to be able to deploy the sensors on a large scale to help figure out why California's Redwoods are dying off at an alarming rate."

Implementing Intercom-like Videoconferencing? 46

Posted by Cliff from the wouldn't-this-be-nice dept.
Tangential asks: "I run a small (~100 person) consulting company with developers located in several locations (including SOHO's.) We run a VPN, so network connectivity isn't an issue. I'd like to improve day-to-day interactions between everyone here and I'm thinking of setting up (for lack of a better term) a video-intercom. I want people to be able to see and converse with each other at their desks, much as they would if they were all in the same office. Some of the folks here use Windows and some of us use Linux. I'm looking for a software and hardware solution that will operate pretty well between them and not swamp my systems staff. I need it to carry both the audio and the video connection and it is safe to assume that all workstations and laptops here are at least 1 GHz units. I'd especially like recommendations on which cameras to use on the Linux boxes."

Multi-function Printer Recomendations? 37

Posted by Cliff from the working-hardware-that's-hard-working dept.
worm eater asks: "My office is thinking about purchasing a multi-function printer/copier (MFP). We are currently looking at the Panasonic Workio 3510, but there is a surprising lack of reviews on the internet (there is one at ePinions). Has anyone had any experience with this model (which went on sale last month) or other similar machines? We are looking for a good B&W copier / laser printer capable of connecting to our LAN. The ability to interface with Exchange and send internet faxes would be nice, but not essential. As with pretty much any copier, we will need high quality support. Thanks in advance, Slashdot."

Solving a Wiring Mess? 769

Posted by Cliff from the cleaning-up-the-rat's-nest dept.
FueledByRamen asks: "While trying to run a new power line for a large Sun mass-storage cabinet (located nowhere near a 220 outlet of course), I had the misfortune of needing to pop the lid on my main power distribution panel (previously opened in the late 80s). The whole thing is a rats nest and probably a fire hazard - old-style wiring with broken-down cloth/plastic insulation strewn everywhere, and the utility's incoming power cables have some sort of junction in them that's the size of a 1-liter bottle (on each wire) and is covered in layers of electrical tape. Even (gently) putting the panel back on jiggled something important, and there was a nasty cracking noise and half the breakers blew (all breakers in one of the 2 columns). I've worked with mains voltage in the past (wiring new rooms, installing lighting), but nothing on this scale, both in terms of complexity and potential for death. How do you industrious Slashdot readers go about fixing a mess like this (on a tight budget, no less) without getting a mains-induced glimpse at the great beyond?"

New WiFi Standards, Double the Data? 163

Posted by simoniker from the tin-can-and-piece-of-string dept.
morkeleb writes "According to the New York Times (free reg. req.), just when you thought it was safe to stock your home or office the 802.11x way, another possibility springs up. From Stanford and Bell Labs comes an approach using MIMO, which 'relies on taking advantage of huge amounts of computing power to send numbers of signals from closely spaced antennas', thereby enhancing range and throughput. Looks like Intel and Nokia are interested in the technology, as well as a number of highroller venture capitalist groups."

Sony Shoots For 4-Filter CCD, 8 Megapixel Camera 405

Posted by simoniker from the color-filter-volume-goes-to-four dept.
Artifex writes "If you're looking to spend about $1200 on a new digital camera, check out this Digital Photography Review look at Sony's upcoming 8 MegaPixel Cyber-shot DSC-F828. The most interesting thing isn't the number of pixels in this prosumer-grade camera, but its 4-color filter CCD system. ['Instead of the traditional RGB color filter array, the new CFA is made up of Red, Green, Blue and Emerald (like Cyan) color filters.'] I've always been a strict Canon fan, but this is making me think twice."

World's First Game-Playing DNA Computer 166

Posted by simoniker from the why's-the-enzyme-always-allowed-to-go-first? dept.
An anonymous reader writes "NewScientist.com posted an article today about the first game-playing 'computer' powered by DNA logic. An interesting read, although not at all a practical alternative for those looking to replace their PlayStation2 with the next great platform." The machine is "...an enzyme-powered tic-tac-toe machine that... uses a complex mixture of DNA enzymes to determine where it should place its nought or cross, and signals its move with a green glow."

Palm Reveals New Name 306

Posted by Hemos from the how-bloody-unexciting dept.
dmehus writes "Milpitas, Calif. based Palm Inc. announced Sunday afternoon the new name and moniker for its handheld hardware business. After almost two years in the planning and focus group stages, the company's Board of Directors and executives decided on PalmOne. PalmOne's ticker symbol will change from the current PALM to PLMO. Sister company PalmSource, which will be the operating system business, takes ticker symbol PSRC. According this report by CNET News.com's Ina Fried, the two companies will be publicly traded, but they will also be controlled by a new holding company. In addition, the Spring 2004 line of handhelds will adopt the PalmOne moniker. Devices that run the Palm OS can continue to say "Palm powered." The new ticker symbols and corporate name changes will take affect some time in late September or early October, once the Palm buyout of rival HandSpring is complete."

Wireless Growth & Wireless Interference 132

No Magic In A Knight's Tour 278

Posted by Hemos from the brute-force-it-baby dept.
morgothan writes "As reported in an article on Math World the solution, or rather lack of solution has been found to the over one hundred fifty year old math problem of how many numbers of magic tours a knight can make on a standard 8x8 chessboard. It turn out that there exist one hundred forty distinct semimagic tours, but no magic tour. The solution came after 61.40 CPU-days, corresponding to 138.25 days of computation at 1 GHz, the project was completed on August 5, 2003 in which every possible enumeration was tried out. The author of the software that finally solved the problem has also put up a webpage in which he further explains the problem and his method of solving it." Thanks to Mig for pointing out a great background page on Chessbase.com.

Carriers Might Profit From Cell Number Portability 184

Posted by michael from the yay-for-oligarchies dept.
Makarand writes "Carriers that are adding cell-number portability fees to your monthly cell phone bills (while fighting against actually implementing the requirement) may actually rake in profits from these levies as the total amounts collected will be more than the projected costs of meeting the FCC's number portability requirements. Although federal law requires that such fees be 'just and reasonable', it does not require reporting of their actual expenses. Consumer advocates feel that the number portability verification processes required are similar to those used by long-distance phone companies when a customer switches from one service provider to another and there is little reason to believe that expenses to meet portability requirements should vary widely among carriers and be so excessive as to bring profits for the carriers."

PowerBook G4 SuperDrive Speed Bump Hack 81

Posted by pudge from the do-not-try-this-at-home dept.
George Wright writes "A guy called cynikal has managed to hack the firmware on the PowerBook G4's "Superdrive" (the Panasonic UJ-815A slimline slot loading DVD-R/RW burner) to enable DVD-R burning at 2x (instead of 1x), DVD-RW burning at 1x (instead of it being disabled), CD-R burning at 16x (instead of 8x) and CD-RW burning at 8x (instead of 4x). Thanks a lot cynikal! The drive now reports as a UJ-815A instead of a UJ-815, and has a firmware revision of D101 instead of the DOC4, DOCB or DWDB the PowerBooks came with. A firmware downgrader can be obtained from the same place to downgrade back to DOCB if you want to, and there is a discussion thread."

Linux on Laptops Manufacturer Report Card Updated 158

Posted by CmdrTaco from the everybody-likes-laptops dept.
wehe writes "The Linux on Laptops Manufacturer Report Card was updated. The changes are based on some of the criticisms the first announcement at SlashDot has got. A matrix of Original Equipment Manufacturers - OEM relations was added together with tips and tricks how to identify the original laptop manufacturer. Also a list of Linux laptop and PDA resellers was added. Unfortunately even in our times of Linux success, support by laptop manufacturers is seldom, or if provided not much helpful. Though the marketing departments of some major manufacturers have announced Linux support for their laptops sometimes, it was not developed or silently dropped. Because of the rapid development (every manufacturer creates new models almost every three months) and the specific hardware of mobile computer devices and accessories (see Linux Mobile Guide for details), it is important to have current and reliable information about their Linux compatibility. A current example is Intel`s new Centrino(TM) technology. Though there are many Linux laptop installation reports available already, Intel still does not provide full Linux support yet. Note: the URL of the original "Linux on Laptops Manufacturer Report Card" has changed from MobiliX to TuxMobil, because of severe trademark trouble with Asterix and Obelix, as reported on SlashDot."

RIM Color BlackBerry 7230 Review 119

Posted by michael from the stuff-to-lose dept.
securitas submits this painfully well-linked piece: "eWEEK reviews the RIM BlackBerry 7230 color handheld, Research In Motion's latest combination wireless e-mail/phone/PDA, and the first BlackBerry to feature a full-color display. The tri-band GSM/GPRS J2ME device features a 240-by-160-pixel, 65,000-color display, 16 MB flash +2 MB SRAM, an Intel 386 32-bit chip, SMS, an HTML browser (missing from the preceding BlackBerry 5810), a claimed 4 hours talk/10 days standby removable/rechargeable lithium-ion battery, POP3/IMAP/Exchange/Notes wireless e-mail for up to 10 accounts with file attachment management, security via Triple DES encryption, USB sync/recharging and the usual organizer functions. RIM squeezes it all into a 4.8 oz/136g, 4.4x2.9x0.8 inch/11.3x7.4x2.0 cm package (tech specs at RIM). The BlackBerry 7230 is exclusive to T-Mobile USA until 2004 and costs about $400. With this release, RIM is moving the BlackBerry into the prosumer/consumer market to expand its customer base beyond enterprise users. The release comes amid speculation of BlackBerry doom following RIM's recent patent ruling loss and ahead of the highly anticipated Handspring Treo 600, its direct competition (which includes the MS Pocket PC Phone Edition Smartphone and the Palm Tungsten W).

New PDA Listens To Your Heartbeat 57

Posted by CowboyNeal from the phoning-home-when-trouble-strikes dept.
Roland Piquepaille writes "CardioNet Inc., a company based in San Diego, has developed a wireless technology to monitor heart patients. According to this Computerworld article, the technology was 'originally developed by Qualcomm Inc. to track and send messages to large truck fleets.' CardioNet's service is initially focused on the 2 million U.S. people suffering from arrhythmia. Each patient is equipped with a PDA-type electrocardiogram (ECG) monitoring device connected by a short-range wireless system to electrodes on his chest. Data is sent to his doctor via a built-in cell phone chip. More details, including a diagram and pictures showing how the system works are also available."
