"Unlike ordinary passive cables that can be used at lower data rates, the unprecedented speed of the new Thunderbolt technology places unique demands on the physical transmission media," according to Gennum's website. "The GN2033 provides the sophisticated signal boosting and detection functions required to transfer high-speed data without errors across inexpensive Thunderbolt copper cables."
an unprecedented civilian search-and-rescue exercise involving satellites, private planes, automated image analysis, ocean current simulations, and crowdsourced human computing, working in collaboration with the US Coast Guard.
As we learned, real-time search for boats at sea is not as simple as getting a satellite feed from a mapping service, or borrowing a private jet.
Our conclusion is simply that the ocean surface is not only very large, but also very empty.
mandate the installation of maritime safety technology in a failsafe way, as we have done with other technologies like automobile airbags. It is both possible and inexpensive (relative to the cost of a boat) to require EPIRB-like technology to be integrated into boat construction.
File systems write the same metadata to multiple logical blocks as a way of avoiding a single block failure causing massive, or in some cases total, loss of user data. An example is the superblock in the UFS (Unix file system). Suppose you have one of these SSDs with a UFS on it. Each of the multiple alternate logical locations for the superblock will be mapped to the same underlying physical block. If any of the bits in this physical block goes bad, the same bit will go bad in every alternate logical superblock.
Not only do SandForce SSD Processors employ ECC protection enabling an UBER (Uncorrectable Bit Error Rate) of greater than 10^-17, if the ECC engine is unable to correct the bit error RAISE will step in to correct a complete failure of an entire sector, page, or block.
Instant answers. New sources of knowledge. Powerful tools—all for free. In just 13 years we’ve built a model that has changed the way people find answers and helped businesses both large and small create jobs and connect with new customers.
The FTC's preparations to subpoena Google are the first concrete signal that the agency's commissioners have decided there is enough evidence to move forward with a formal investigation. The probe is expected to take a year or more to unfold, and it won't necessarily lead to any charges.
Imagine that you have been given the task to design a shipping-container cluster containing 1000 server-class computers. The container provides the necessary power and cooling, you have already chosen the servers, and now you must choose a network to connect the servers within the pod.
The most common form of scareware is fake antivirus (AV) software, also known as "rogue security software." More specifically, a fake AV program impersonates an antivirus scanner and displays misleading or fraudulent alerts in an attempt to dupe a victim into purchasing a license for a commercial version that is capable of removing nonexistent security threats.
have been able to acquire backend servers for several multi-million dollar criminal operations selling fake AV products.
...
Since we have access to the servers used by these criminal organizations, we are able to directly analyze the tools that are used to create the fake AV products, including programs that assist perpetrators in controlling the malware's behavior and brand names, as well as custom packers that obfuscate the malware to evade detection by legitimate antivirus products.
This unprecedented access allowed us to obtain ground truth about the type and sophistication of the techniques used to lure victims into paying for scareware, as well as the amount of transactions performed, including refunds and chargebacks.
An interesting facet of fake AV sales is the process in which credit card transactions are handled. In particular, payment processors (also known as payment service providers) are an integral part of every sale. Without these processors, fake AV operations would not be able to accept credit card payments. This would make it not only harder for a victim to purchase the product (i.e., they would have to use an alternative form of payment, such as cash, check, or money order), but it would also likely raise red flags that the software may be fraudulent. Note that payment processors must maintain a degree of legitimacy, or they risk losing the ability to accept major credit cards.

Perhaps the most notorious payment service provider is Chronopay, which ... has long been associated with processing transactions for various forms of online criminal organizations ... [H]owever ... also provides legitimate services to large organizations such as [ an amazing list of top-shelf names follows ]
I imagined myself working montage-like through the book, smoothly accruing expertise one chapter at a time.
What happened instead is that I burned out after a week. The text itself was dense and unsmiling; the exercises were difficult. It was quite possibly the least fun I've ever had with a book, or, for that matter, with anything at all. I dropped it as quickly as I had picked it up.
What's especially neat about it is that someone who has never programmed -- someone who doesn't even know what a program is -- can learn to write code that solves this problem in less than three hours. I've seen it happen. All it takes is a little hunger. You just have to want the answer.
# include <stdio.h>
int main( int argc, char *argv[] )
{
int answer = 0;
for (int i = 1; i < 1000; i++)
if( i%3 == 0 || i%5 == 0 )
answer += i;
printf("Answer to Project Euler problem 1: %d\n", answer);
return 0;
}
What you'll find there is something that educators, technologists and journalists have been talking about for decades. And for nine years it's been quietly thriving on this site. It's the global, distributed classroom, a nurturing community of self-motivated learners -- old, young, from more than two hundred countries -- all sharing in the pleasure of finding things out.
A system comprising: units of a commodity that can be used by respective users in different locations, a user interface, which is part of each of the units of the commodity, configured to provide a medium for two-way local interaction between one of the users and the corresponding unit of the commodity, and further configured to elicit, from a user, information about the user's perception of the commodity, a memory within each of the units of the commodity capable of storing results of the two-way local interaction, the results including elicited information about user perception of the commodity, a communication element associated with each of the units of the commodity capable of carrying results of the two-way local interaction from each of the units of the commodity to a central location, and a component capable of managing the interactions of the users in different locations and collecting the results of the interactions at the central location.
Abelow's independent investions emerged from conceiving a new type of operating environment for individuals, corporations, and societies, to make self-determined improvements in their quality of life.
the authors of twenty-five open source applications explain how their software is structured, and why. What are each program's major components? How do they interact? And what did their builders learn during their development? In answering these questions, the contributors to this book provide unique insights into how they think.
The goal is to preserve one copy of every published work. The universe of unique titles has been estimated at close to one hundred million items. Many of these are rare or unique, so we do not expect most of these to come to the Internet Archive; they will instead remain in their current libraries. But the opportunity to preserve over ten million items is possible, so we have designed a system that will expand to this level. Ten million books is approximately the size of a world-class university library or public library, so we see this as a worthwhile goal. If we are successful, then this set of cultural materials will last for centuries and could be beneficial in ways that we cannot predict.
