bsk_cw writes "Brian Nadel got hold of cellular network cards from AT&T, Sprint, and Verizon, and tried them out with a Lenovo ThinkPad X300 notebook. He watched videos on commuter trains, worked with e-mail at cafes, listened to Internet radio at the airport, and downloaded large files while in a moving car. AT&T came out on top in his tests in the New York area (summary here). Some of the reader comments report different conclusions, so a YMMV is in order."

AnInkle writes "A blogger on The Tech Report details his research and testing of wireless voice communication options for remote mountainous villages in rural undeveloped areas. The home-built project involves open-source software, low-cost wireless routers, solar power, mesh networking, unlicensed radio frequencies and VoIP technology. Although his research began several months ago, he has concluded the first stage of testing and is preparing to move near one of the sites where he hopes to eventually install the final functional network. Anyone with experience or ideas on the subject is invited to offer input and advice."

paradoxSpirit writes "Physorg has a paper comparing the cost of text messaging versus the cost of getting data from Hubble Space Telescope. From the article: 'The maximum size for a text message is 160 characters, which takes 140 bytes because there are only 7 bits per character in the text messaging system, and we assume the average price for a text message is 5p. There are 1,048,576 bytes in a megabyte, so that's 1 million/140 = 7490 text messages to transmit one megabyte. At 5p each, that's £374.49 [$732.95] per MB — or about 4.4 times more expensive than the 'most pessimistic' estimate for Hubble Space Telescope transmission costs." "Hubble is by no means a cheap mission — but the mobile phone text costs were pretty astronomical!""

Nerdposeur writes "Google has announced that it will partner with several other companies to build a high-speed mobile data network. In a separate but related deal, Google will also become the default search provider for Sprint, including having one-click search access and Google Maps pre-installed on some Sprint phones. 'The consortium includes a disparate group of partners: Sprint Nextel, Google, Intel, Comcast, Time Warner and Clearwire. The partners have put the value of the deal at $14.5 billion, a figure that includes radio spectrum and equipment provided by Sprint Nextel and Clearwire, and $3.2 billion from the others involved. They expect the network, which will provide the next generation of high-speed Internet access for cellphone users, to be built in as little as two years, but there is no timetable on when it will be available to users and the price is not determined. The partners are seeking to beat Verizon Wireless and AT&T Wireless to the market.'"

schliz writes to mention that in a recent interview with ITNews researcher John Shalf explained the purpose and some of the technical details of the newly-announced "iPod supercomputer." "Microprocessors from portable electronics like iPods could yield low-cost, low-power supercomputers for specialized scientific applications, according to computer scientist John Shalf. Along with a research team from the US Department of Energy's Lawrence Berkeley National Laboratory, Shalf is designing a supercomputer based on low-power embedded microprocessors, which has the sole purpose of improving global climate change predictions."

An anonymous reader writes "The Kindle made waves when it came out, but they've now had the chance to calm. How many of you have been using your eBook readers since you've received them? How many of you forgot you had one, and how many of you swear by your reader? I like my single-purpose (well, dual — music player) Sony Reader because I actually use it to read, rather than multitasking myself to death. Is this technology as convenient and useful as you expected?" If not, what refinements or improvements would reKindle your interest?

Ian Lamont writes "Terrence Russell has outlined an interesting theory about what industry Apple intends to break into next. He points to games. Forget Pippin II, or an iMac gaming rig — he thinks the mobile realm is where Apple will make a big product push. It's not the first bit of speculation about Apple's renewed interest in gaming, but Russell's theory may have more legs, considering Apple's invitation to develop games on the iPhone SDK, its strong mobile product line, and a Apple trademark extension filed three months ago."

KrispyDollars writes "It sounds crazy to say this, but the XP-based version of the Eee PC 900 (the new version with the 8.9" screen) will actually be considerably cheaper than the Linux-based version. At the official launch today, the company told journalists that 'Microsoft has been a longstanding supporter of Asus' to explain the price discrepancy. And — get this — only the XP-based machine will be sold at mass-market retailers, while the Linux-based model will be consigned to computer stores."

Mike writes "As if the Zune wasn't already crippled and unpopular enough, now comes a story indicating that Microsoft may build a 'Copyright Cop' into every Zune. A future update of the software for Microsoft's portable media player will likely include a 'feature' that will block unauthorized copies of copyrighted videos from being played on it. The president of digital distribution for NBC, J. B. Perrette, said the plan is to create 'filtering technology that allows for playback of legitimately purchased content versus non-legitimately purchased content.' Of course there's no way to tell legitimate content that you create from 'non-legitimate' content, so this looks like just another nail in the coffin of the Zune." Update: 05/08 20:50 GMT by T : From Microsoft employee Cesar Menendez comes this categorical denial of any such filtering mechanism.

Stony Stevenson writes "It has surfaced that the US State Department can't account for up to about 1,000 laptops, perhaps as many as 400 of which belonged to the department's Anti-Terrorism Assistance Program. Internal auditors found that the department lost track of $30 million worth of computer equipment, 'the vast majority of which... perhaps as much as 99 percent,' were laptops, according to one official. Another official calculated that the average State Department laptop costs US$3,000 and figured that meant as many as 1,000 laptops might be astray — not 10,000 laptops as the US$30 million figure suggests. They're obviously not very good at maths."

An anonymous reader sends in a Seattle PI story about the use of cell phone records in missing-person cases. Typically, phone companies turn over location information to police without a warrant if one of their customers is reported missing; the police need only to state that the person may be in danger. In any criminal case, a warrant from a judge would be required before the telcos divulged any information. While in some poster-child cases lives have been saved as a result of this practice, it seems like a class-action lawsuit waiting to happen. It is not a crime to go missing.

Ian Lamont writes "Google is so worried about Verizon Wireless's commitment to open access using the 700Mhz spectrum that it has asked the FCC to get a pledge from Verizon that the carrier will honor the FCC's open-access conditions before the FCC sells it the band. Verizon won the auction for the nationwide C block of the 700MHz spectrum, but Google points to Verizon's alleged attempts to abandon the conditions, including a filing with the FCC which said the commission 'could not force the C block winner to allow all applications on the network.' Could this be another expanding front in the Net Neutrality battle, or is it time for the carriers to accept the fact that Net Neutrality is essentially a done deal, and carriers need to prepare for the next battle — developing software and services to run on open networks?" The IP Democracy blog has Google's filing (PDF) and the following comment from Verizon: "Google's filing has no legal standing."

The Christian Science Monitor has an interesting look at the war brewing on the inexpensive laptop front. With everything from the Eee PC to the OLPC, the trend in slimming and trimming seems to be continuing. "The market segment is so new it doesn't have a name yet or even an agreed-upon set of specifications. Intel, the chipmaker, calls the category "netbooks," recognizing that much of what people do on their laptops involves going on the Net. The new machines are also being called ultra-low-cost PCs, mininotebooks, or even mobile Internet gadgets. In appearance, they have the familiar clamshell design, but they're smaller, with seven- to 10-inch screens. They offer full keyboards (albeit with smaller keys) and weigh less than three pounds. Perhaps most important, the majority cost less than $500 - some as little as $299. Intel says it expects more than 50 million of these netbooks to be sold by 2011. It's introduced a tiny, low-power processor to run them called Atom, which puts 47 million transistors on a chip about the size of a penny."

A few days ago, Dan Rutter (the Dan in "Dan's Data") published an interesting idea for extending the sort of philanthropic technical pranksterism that spawned throwies by applying the same approach to Wi-Fi. That means, looking what he hopes is not too far down the road, creating Wi-Fi repeaters that are cheap enough to deploy on the sly and frugal enough with power to run on solar power or cheaply replaceable batteries. But as he says, "If you've got a lot of spare money, a ladder and no respect for private property, though, you could already be stealthily deploying Open-Mesh or other such gadgets all over your neighbourhood." In some cities at least, you'd be hard pressed to ever avoid at least one available wireless access point, but that's not the experience for most people, most places -- which bears correction.

SecureThroughObscure writes tells us about a hack broken by MacOSRumors: you can get free Wi-Fi at Starbucks, Barnes & Noble, and other AT&T hotspots if you know how to set your browser's user agent string (trivial on Safari), and know a valid iPhone phone number. ZDNet blogger Nate McFeters gives some more details and links. This can't last.

praps writes "Two German companies have patented technology for sending scented text messages between mobile phones. The chip, which carries a range of around 100 pre-defined scents, has been developed by the Institute of Sensory Analysis and interactive services firm Convisual and will be on the market in one to two years. Naturally, the makers think that the chip will be used for sending pleasant odors to friends and family — vanilla, rose and Christmas cinnamon are on the list — but surely the claim to be able to send 'the smell of the beach and sunshine' is a little optimistic? SMS stink bombs cannot be far away."

Engadget is reporting that AT&T will be launching their Mobile TV service on May 4th. The article features a few details and a video of the tech in action. "You'll find Mobile TV running on LG's new $300 (2-year, after $100 rebate) Vu, one of just two Mobile TV compatible handsets launching on AT&T May 4th — the other being the $200 (2-year, after $100 rebate) Samsung Access. Performance looks reasonably snappy when scrolling through the channel guide although some of the exclusive PIX and CNN Mobile Live content is not yet available. S'ok, AT&T has three more days to throw the big blue switch on the broadcast TV service which includes a $15/month unlimited Mobile TV access plan."

Sastira writes "Jordan Bunnell has successfully modded his Macbook Air to use an internal EVDO Broadband card. In order to make everything fit, he had to sacrifice the WiFi and bluetooth cards, but considering the portable nature of the laptop, it is a small price to pay for being truly wireless." (You'll need to scroll down past the sketchy-looking top section of that page.) Sastira also links to this InsanelyMac forum thread on the mod.

TeknoFin notes a piece in the NYTimes on the fight RIM finds itself in as the smartphone market shifts to a consumer focus, impelled by the iPhone. For the last 10 years RIM has dominated a smartphone market consisting mainly of email-obsessed corporate professionals. Analysts wonder if RIM can hold on to their lead as their strengths — such as cozy relations with cell carriers worldwide — are diluted by new entrants Apple and Google, who are "vocally trying to dislodge the carriers from the nexus of the North American wireless market." One of RIM's strengths in the corporate market has been their security. Yet Apple executives have said that one-third of Fortune 500 companies were interested in giving iPhones — with all their known and potential security holes — to their employees.

Stony Stevenson alerts us to comments from OLPC founder Nicholas Negroponte indicating his approval of Windows' performance on the XO laptop. Negroponte said in an email, "Sugar needs a wider basis, to run on more Linux platforms and to run under Windows." The full email is available at OLPC News. He was also quoted by the Associated Press as saying that Sugar "didn't have a software architect who did it in a crisp way," and cited the lack of Flash as an example. Negroponte continued, "There are several examples like that, that we have to address without worrying about the fundamentalism in some of the open-source community. One can be an open-source advocate without being an open-source fundamentalist."
