Samsung and Sun Microsystems have developed a flash chip for use in solid-state drives that offers higher endurance levels than current devices, the companies say.
The chip is targeted at server applications.Samsung solid-state drive
The Samsung flash memory chip is based on single-level-cell NAND flash technology and offers a fivefold increase in data write-and-erase cycles over standard SLC flash memory, according to Samsung.
SLC-based flash chips are faster and offer more write-and-erase cycles than multilevel cell -based devices. MLC, however, offers greater capacities and lower cost, making it suitable for notebook computers. MLC-based solid-state drives from Samsung, Intel, Micron Technology, and Toshiba are expected to flood the market in the second half of the year.
Samsung's new SLC NAND memory is designed for server-grade SSDs, particularly high-transaction data processing servers. The "ultra-endurance" memory has been developed in close cooperation with Sun over the past several months, Samsung said.
"We have been working with Sun to develop this new...server-grade SLC flash memory, which will give IT managers the best in high-density, high-endurance memory design with markedly less energy consumption than we see today," Jim Elliott, vice president of memory marketing at Samsung Semiconductor, said in a statement.
Probable applications include video streaming and search engine operations. The chip will provide a 100X increase over conventional hard disk drives in the number of data transfers per watt, offering significant power savings, according to Samsung.
Sun said it plans to incorporate the technology into its line of servers and storage, according to Michael Cornwell, lead technologist for flash memory at Sun.
Attempts to assert your right to fly without ID can often be very frustrating, due to Transportation Security Administration and airport officials not knowing their own rules.
With any luck, this should no longer be an issue because the TSA has, at last, clarified things.
Passengers with tickets for domestic flights are under no obligation to present ID to TSA. Passengers may be required to show ID to airline employees, but that is a contractual matter between the airlines and their passengers. U.S. government employees cannot, however, require you to show ID in order to pass through the security checkpoints.Poster at Burning Man '06
I have personally flown over a dozen times without showing a single form of ID. A number of others have documented similar success stories. Unfortunately, some TSA employees are not aware of their own rules, and at times, have forced passengers to produce ID. Blogger Jake Appelbaum has documented one such experience. Something similar happened to me earlier this year when TSA agents brought over an airport police officer who then compelled me to produce an ID.
The 9th Circuit Federal Court of Appeals clarified a passenger's right to travel without showing ID in its ruling in Gilmore v. Gonzales . Expecting that a TSA screening agent be able to parse a court opinion is often a losing battle. It is for that reason that I've spent the last few months sending letters back and forth to TSA, via my senator, which at least guarantees a reply. Eventually, I was able to get something from TSA in writing that confirms passengers are able to legally fly without showing ID. For those of you who'd like to give it a shot, print out this letter and take it with you. It should reduce any push-back you get from TSA agents.
For those of you who don't get a kick out of asserting your rights, you may wonder why you would ever want to do this. After all, those passengers who decline to provide ID to TSA will instead be forced to go through an invasive "secondary screening" process--a five-minute-or-so procedure in which passengers are patted down, poked, prodded and have their carry-on bag thoroughly searched by hand.
There is a little known, but extremely useful side effect of refusing to show ID: In many airports, you get bumped to the front of the security line. As illogical as it may seem, you can often get through security faster by refusing or "forgetting" your ID at home than if you followed the normal security process.
So, the next time you fly, use my letter and repeat after me: "I hereby assert my right to fly without showing an identification document to any government official." With any luck, you should get through without any problems, and more than likely, you'll get bumped to the front of the queue. If you get any push-back at all, remember the magic words, "I'd like to speak to a supervisor please."
For further reading on the subject: I have a research paper documenting security flaws in the boarding pass system and no-fly lists that'll be published at the IDMAN workshop in October. A pre-print copy of the paper is available online: Insecure Flight: Broken Boarding Passes and Ineffective Terrorist Watch Lists . Researchers from MIT analyzed the benefits of racial profiling in airport security back in 2002. I highly recommend their paper, Carnival Booth: An Algorithm for Defeating the Computer-Assisted Passenger Screening System . Bruce Schneier has been talking about airport security flaws for years, and most recently published a must-read interview with TSA chief Kip Hawley.Letter from TSA Click to see a full-size copy . .

An Israeli company has conducted the first in a series of test flights on the Panda, a new ducted-fan, unmanned aerial vehicle prototype that looks kind of like a flying stretcher, bringing us closer to what could be the ultimate medivac.
The company, Urban Aeronautics , already produces the Mule UAV and the X-Hawk , larger versions that can be configured for front-line resupply, medical evacuation, utility maintenance, taxi, high-rise rescue, and probably window cleaning.
The technology is based on the "classic ducted designed pioneered in the early 1960s," as the company Web site points out. This model relies on two electric motors and can carry about 3 pounds in payload, enough to deliver an organ for transplant. However, the company's patented quiet, "rotorless" Fancraft technology promises to eliminate the safety hazards associated with helicopters. And the fact that it can maintain a stable hover next to walls, slopes, electrical wires and the like and that it's able to land safely in tight spots could mean you may soon have something to drive in that hereto now neglected space between the roofs and the road. Now, if it could just run on solar.
Many Gmail users had problems with the Google e-mail service's ability to communicate with e-mail software Wednesday.
Numerous people on a Gmail Help forum reported problems tapping into Gmail with IMAP technology, which lets people with desktop e-mail software such as Thunderbird or Microsoft Entourage to do so.
Google acknowledged the problem but said it's fixed. "Gmail users had difficulty accessing some features in Gmail for about a half hour today. The issue is now resolved," the company said in a statement Wednesday.
"We take issues like this very seriously, and we encourage anyone who is having technical difficulty of any kind with Gmail to contact the Gmail Support team through the Gmail Help Center ."
The glitch came at an inopportune time. Google is trying to encourage not just individuals but also companies to use its online services; Google Apps, of which Gmail is a component, features prominently in a Google alliance with Salesforce.com .
"A huge, if not number one selling point for moving one of our companies over to Google Apps was Google's robust network!" complained one user . "Now that we have migrated over, it seems we are abused children who do not deserve an explanation for why the service we pay for is taken offline. Perhaps it is time to find a new e-mail host."
I can't help but notice that after all these years, Gmail still technically is in beta testing, a strong signal that people should be cautious about relying on it.
Technically, only one such convention is needed, the press release points out , as time travelers from all eras could meet at a specific place and time, and then make as many repeat visits as they wanted.
"Write the details down on a piece of acid-free paper," implores the announcement, "and slip them into obscure books in academic libraries! Carve them into a clay tablet! A note: Time travel is a hard problem, and it may not be invented until long after MIT has faded into oblivion. Thus, we ask that you include the latitude/longitude information when you publicize the convention." We realize this is kind of last-minute notice, so if you're busy next weekend, not to worry. You can always attend in 4678.
Verizon Wireless is launching its V Cast TV service on March 1 in select markets, according to the company's Web site. RCR Wireless News was the first to notice and report the launch date.
When the service was announced at the Consumer Electronics Show in Las Vegas in January , Verizon said it would be available during the first quarter, which ends March 31.
V Cast TV offers viewers full-length and live programming from a number of networks, including NBC, CBS, Fox and MTV. V Cast TV is the first mobile television service to use MedioFlo, a dedicated video broadcast network built and owned by Qualcomm . Qualcomm announced that Verizon would be using the network in 2005.
AT&T's Cingular Wireless announced earlier this month it also will use MediaFlo to deliver mobile TV. And Sprint Nextel, which also offers a video service over its 3G cellular network, has been testing the MediaFlo network since last year. But Sprint has not announced whether it plans to offer a live TV broadcast service to its subscribers using MediaFlo.
