SanDisk makes 128-gigabit flash chip, crams three bits per cell, takes afternoon off

SanDisk has developed a chip that earns it membership in the exclusive 128-gigabit club. Not content with simply matching the Micron / Intel effort, SanDisk and its partner Toshiba claim their new memory uses 19- rather than 20-nanometer cells in the production process. Shrinking the size is one thing, but SanDisk’s new chips also use its X3 / three-bit technology. Most memory stores just two bits per cell; cramming in another means fewer cells, less silicon, more savings, cheaper memory, happier geeks. Analyst Jim Handy estimates that the price per gigabyte for the tri-bit breed of flash could be as low as 28 cents, compared to 35 for the Micron / Intel equivalent. Full details in the not-so-compact press release after the break.

1024-bit RSA encryption cracked by carefully starving CPU of electricity

Since 1977, RSA public-key encryption has protected privacy and verified authenticity when using computers, gadgets and web browsers around the globe, with only the most brutish of brute force efforts (and 1,500 years of processing time) felling its 768-bit variety earlier this year. Now, three eggheads (or Wolverines, as it were) at the University of Michigan claim they can break it simply by tweaking a device’s power supply. By fluctuating the voltage to the CPU such that it generated a single hardware error per clock cycle, they found that they could cause the server to flip single bits of the private key at a time, allowing them to slowly piece together the password. With a small cluster of 81 Pentium 4 chips and 104 hours of processing time, they were able to successfully hack 1024-bit encryption in OpenSSL on a SPARC-based system, without damaging the computer, leaving a single trace or ending human life as we know it. That’s why they’re presenting a paper at the Design, Automation and Test conference this week in Europe, and that’s why — until RSA hopefully fixes the flaw — you should keep a close eye on your server room’s power supply.

Behold, the power of a scary-sounding letter from a lawyer! Paul dropped his Kindle 2 and it broke. Amazon wanted $200 to replace it. Instead, they replaced it and gave him an additional $200. Damn, son!
Seriously, how badass is this letter he sent to Amazon?
Paul Gowder
[Address omitted]August 12, 2009
Amazon.com Inc.
Legal Department
1200 12th Avenue South
Suite 1200
Seattle, WA 98144-2734Dear Sir or Madam:
On June 21, 2009, I purchased an Kindle 2 e-book reader from the Amazon.com website. I purchased this device based, in substantial part, on the expectation that it would be reasonably durable. In particular, I expected that it would be approximately as durable as is ordinary in the consumer electronics market.
Amazon.com advertises the Kindle 2 on the basis of its durability. Notably, Amazon.com displays a “drop test” video on the web page for this product. That video displays the device being dropped twice from thirty inches onto what appears to be tile. That video displays a fall with sufficient force that the device visibly bounces, and deliberately creates the impression that the device will function after impacts similar to that sequence of drops.
Despite those representations, the Kindle 2 is far less durable. On July 26, 2009, I dropped a messenger bag containing the device onto the sidewalk, from approximately two feet above the ground. It was dropped only once, and the messenger bag absorbed enough of the shock that nothing else in the bag, including a Macbook laptop, suffered an! y damage whatsoever. (Unlike the drop displayed in Amazon.com’s video, for example, nothing actually bounced.) Moreover, there was no visible damage on the exterior of the Kindle 2. Nonetheless, the Kindle 2 became completely unusable, with over 50% of its screen no longer able to display any text.
I called Amazon.com support and was told that, because of the accidental drop, you would not be willing to supply a replacement device under warranty. You did, however, offer to sell a new device at a discount, for $200.00. I took advantage of that offer under protest, and explicitly reserved my rights to bring a claim against you based on the unreasonable fragility of the device and the misrepresentations in your advertising. It is that claim that forms the subject of this letter.
I am prepared to offer an immediate settlement of my claims against Amazon.com for a payment of $400.00. That sum represents the $200.00 replacement fee I paid plus $200.00 to compensate me for the diminution of utility and value of the device as well as of the e-books I have purchased for that device, in light of the fact that the replacement device, too, can be expected to be far more fragile than advertised and prone to destruction under the slightest stress. This offer expires thirty days from your receipt of this letter. If you do not accept this offer, I intend to bring suit either individually, or, if I decide it is warranted, as representative for a class of similarly situated plaintiffs. At that time, I will seek the amount noted above, plus punitive damages under the California Consumers Legal Remedies Act, Cal. Civil Code §1750 et. seq., costs, fees, and such other monetary damages as provided for by law, including without limitation Cal. Bus. & Prof. Code §17200 et. seq., the implied warranties of merchantability and fitness for a particular purpose, and other relevant law.
Also, you have demanded the return of the broken device as a condition to the unreasonable discounted replacement offer which I accept! ed under protest. Your agent has informed me that you will charge my credit card for the full price if the broken device is not returned to you. I am considering seeking a protective order placing that device in the custody of the Court pending litigation. However, should I instead return the device, you are hereby notified that it is evidence in the anticipated litigation to which this letter refers. Should you modify, destroy, or resell the broken device, I will ask the Court to treat that as deliberate spoliation of evidence and make adverse inferences as appropriate.
Very truly yours,
Paul Gowder
And here’s Amazon’s response:
Pretty awesome. Just goes to show that if you put your somewhat-unreasonable request in an official-looking form and also threaten to sue, big companies will be happy to toss a token amount of money your way to make you go away. [Consumerist]
