aberson writes "Verizon Wireless announced today that it is rolling out a PTT (push to talk) phone service, targetted at business customers. They claim better coverage, 'presence' (away/available), and wireless web for about $10 more than Nextel and $10 more than a non-PTT Verizon plan. Pricing doesn't mention how 'high-speed' data will roll into this (which you can't get on Nextel), but you are using the CDMA2000 network to essentially do VoIP. If only it could be something cross-networkable like Sonim. Just wait a few months for the other carriers to catch up and cellular number portability to be enforced. Ironically, you can only get it on a Motorola made phone. Also, Verizon seems to be not caring about Nextel trying to copyright a generic technical term."

Merlin83 writes "As being reported on The Register, the US Military is developing a new system for monitoring enemy battlefield communication. Called WolfPack, each node is a 6"x4" cylinder, launched by missile or dropped from aircraft. Once the node lands, it stands up, extends its antenna and contacts other nodes. The nodes can also jam cellular communications by transmitting a signal themselves. "

PReDiToR writes "At Tom's Hardware I found this favourable review of some remarkable Hard Drives. The article points out that with 40GB units suitable for server or desktop use, life with 2.5" drives could be just around the corner. Heat noise and power consumption are all apparently within acceptable tolerances."

securitas writes "In case you can't wait until September to find out what it's like, Walt Mossberg reviews the Sony Clie UX50 (as previously discussed). He likes it, but with reservations. The keyboard lacks predictive text (unlike the Handspring Treo and RIM BlackBerry) and the Clie Mail e-mail software can't read graphical e-mails and has poor attachment support. The audio player only reads files from a particular directory. He likes the 802.11b WiFi and loves the 450x320 screen. The biggest problem? The $700 price tag ($600 for the non-wireless UX40 model) - equivalent to a low-end laptop - especially since it doesn't come with a Memory Stick. If you can read it, here's a Japanese Clie UX50 review and PalmInfocenter press release rewrite."

ptorrone writes "In November of 2002, I was able to see the self-balancing iBot mobility device, which can go up and down stairs and travel/balance on two wheels, in person. It literally brought tears to my eyes seeing what it will mean for millions of disabled people around the world. Today, the FDA has approved its use, after years of approval processes and testing." We've mentioned this Dean Kamen-created product previously, but it's good to see it officially approved and available for those who need it.

Bingo Foo asks: "My company is in the process of reviewing replacements to our existing multi-platform VPN, which has now been discontinued. I was under the impression that every major vendor's OS ships with a VPN configuration solution. What gives? Are these not standard enough? Are they not secure enough? not flexible enough? Regardless, our IT department is leaning toward a clientless, web-based solution, which frankly sounds too good to be true. Can simply directing your browser at the portal allow X11, NFS, SMB, AFP, ssh, etc. transparently through the firewall? Anyone have experience with Neoteris and their VPN?"

Tom asks: "The time has come for me to upgrade the audio on my computer. This was last discussed, here.My specific area of interest, is the sound card, in its various embodiments. Two cards that I am considering are Creative Labs' Audigy2, and M-Audio's Revolution 7.1. These companies also have USB counterparts to their products - the Extigy and the Sonica Theatre - and I can't decide if USB's portability and other various advantages justify its shortcomings. Experiences, anyone?"

Luciq asks: "The other day I was cleaning out my closet and started reminiscing about all the good times I had with my 33Mhz 486DX. I got the machine 10 years ago just as the first Pentiums were coming out. With a 33Mhz processor, 212MB hard drive and a whopping 8MB of RAM, I could surf the net at 2400 baud, manipulate photos and even play games with full-screen video like The Seventh Guest. Today I use an Athlon XP 2400, 80GB HD, 512MB [not 512K!] RAM. While I can do some neat things with it, I must say that it's fallen short of the wonderous expectations I had for such a system in 1993 (no immersive VR?, no seamless voice recognition?). What expectations did you have for today's PC, 10 years ago and how does the reality match up? What do you expect from computing, 10 years from now?"

frink_exp asks: "Cleaning mouse balls (and the rollers they contact) has been the source of many a pun and the subject of countless junk e-mail messages. As more optical mice replace their mechanical kin, such hygiene is becoming unnecessary. However, the mouse wheel is nearly as common as the mouse itself and human hands are grubby, sweaty, oily appendages. Invariably, a nice coating of gunk envelops the wheel. Sometimes it's just unsightly, but at it's worst, it'll sap the rubber wheel of all its grip making it difficult to scroll. Cleaning the wheel can be awkward as it tends to spin and unlike mouse balls, it doesn't just pop out (rehashing of the balls joke intended). The best method I've found is scraping sideways, parallel to the wheel's axis of rotation, slowly working my way around the whole wheel. This is tedious and annoying. Is this a common affliction? What is a better, easier way to clean the mouse wheel? Solvents? A wheel brush? Fire?"

An anonymous reader asks: "I have recently (as in today ) acquired a 250GB external HD with both USB2 and Firewire ports, with an eye to using it to carry around all my stuff (my humungous e-mail archive, ISO images of whetever distro I'm running, music and work files - I do a lot of database work, so I often need to move 40GB+ database dumps). The thing is, In order to make proper use of it I have to be able to mount and write to it on all three platforms I use: Windows (easy, it comes formatted as FAT32), Linux (trivial mount syntax) and Mac OS X (it just works as is, since it also supports FAT32). However, I'd like to get rid of FAT32." What filesystems, aside from the FAT varieties, have decent support across the major operating systems?

lucasw writes "The Japan Earth Simulator outperformed a computer at Los Alamos (previously the world's fastest) by a factor of three while using fewer, more specialized processors and advanced interconnect technology. This spawned multiple government reports that many suspected would ask for more funding in the U.S. for custom supercomputer architectures and less emphasis on clustering commodity hardware. One report released yesterday suggests a balanced approach."

Adam Ernst asks: "I'm trying to build a low-end tablet PC type device for giving tests to students in a classroom. The touch screen TFT wasn't hard to get and the WiFi shouldn't be too hard either, but the most difficult part has been finding a motherboard! I tried Via's Mini-ITX, but it was too tall at about 1.5 inches. The motherboard needs to be just three quarters of an inch tall; the length and width can't exceed 8 inches each, but the smaller the better. No fans allowed--this has to be silent. The -only- requirements feature-wise are that it is able to connect to a TFT-LCD, has either USB, CompactFlash, or PCMCIA for WiFi, and has enough power to run Red Hat or SuSE (the only Linuxes my IDE supports). No ports, no ethernet, not even sound. Preferably it would take straight power (just one wire in and one out, at some set voltage) so I don't have to mess with power circuits. Of course, the most important factor of all is cost, since it's for schools (preferably less than $100 in small quantities ~90 units)."

wackoman2112 writes "According to this article, ranchers on western cattle ranches are keeping track of their cattle with the "OptiReader," a small handheld which takes retinal scans. They scan a cow's eye and record information in the database about the animal's color, weight, and genetic linage. Hmmm... This could be justification for a YRO for animals."

Huxley_Dunsany asks: "Yesterday, while attending the (super-duper cool and fun) Classic Game Expo here in Las Vegas, I was lucky enough to trade some old game stuff (Intelivision II, ZX-Spectrum, some Neo-Geo Pocket games) for a really neato black Sony Playstation 'Net Yaroze' edition. For those that don't know what I'm talking about, back in '97, Sony came out with a (very) limited edition of the plain old Playstation. Back in the day, the 'Yaroze' PSX ('Yaroze' supposedly means 'Lets do it together') came with some special cables and software for PC/Mac, and, given enough time and effort and programming talent, you too could create your own Playstation games! Unfortunately, the Yaroze I got yesterday came with nothing but the main CPU - no software, and none of the special PSX-to-PC/Mac serial cables. This morning, I hooked it up and hit the power button, and it fired right up with no problems! So, I'm just wondering if any of you have ever used this seemingly rare dev system, and if you could pass along any good ideas or advice. It seems that Sony has long since discontinued this program (and then recently started it again with the PS2 Linux kit), so I'm not sure where to turn for help if I actually wanted to use this thing to make some games, let alone finding/creating the cables and software."

LilJC asks: "I work at a company that does service work nationwide for a major chain. Our vendor requires a signature for every visit to every store. We have been running thus far from ICR on faxes and linking to the faxed signature image on our web site, but are having numerous problems trying to depend on a thousand+ faxes a month coming through perfectly. We are looking for an economical alternative that would allow a contractor in the field to get a signature and transmit it to us in an system I can idiot-proof. Something along the lines of the UPS guy's digital clipboard, but without the pricetag of a Telxon. Brainstorming myself, I wonder if there must be a cheap PDA/modem combo or the like that would allow a contractor to enter required visit information, get a store signature, go home, plug it into their phone line (without needing a computer), and hit send. I can code and am not afraid of doing some custom work for an app on a handheld. Does the Slashdot community know of any projects along these lines, or have ideas about a wise choice for hardware to homegrow the software on?"
