Such a weakness could be used to launch targeted attacks that track users online activity.
Forcibly terminate a communication, hijack a conversation between hosts or degrade the privacy guarantee by anonymity networks such as Tor.
Led by Yue Cao, a computer science graduate student in UCR’s Bourns College of Engineering, the research will be presented on Wednesday (Aug. 10) at the USENIX Security Symposium in Austin, Texas. The project advisor is Zhiyun Qian, an assistant professor of computer science at UCR, whose research focuses on identifying security vulnerabilities to help software companies improve their systems.
While most users don’t interact directly with the Linux operating system, the software runs behind-the -scenes on internet servers, android phones and a range of other devices. To transfer information from one source to another, Linux and other operating systems use the Transmission Control Protocol (TCP) to package and send data, and the Internet Protocol (IP) to ensure the information gets to the correct destination.
For example, when two people communicate by email, TCP assembles their message into a series of data packets — identified by unique sequence numbers — that are
What makes a processor look so great? Somebody saythat it’s how expensive it is, while others suggest it’s the number of cores or its overclockability that determines the quality of a CPU. In reality, it’s a matter of personal preference backed by some hard numbers.
You would likely be disappointed if you shelled out a small fortune just to build a machine that only ends up being used for typing up documents. Likewise, thinking you could save some money by skimping out on the CPU in your gaming rig would be an equally misguided decision.
Here are our picks for the top 10 best processors you can find right now for your desktop PC.
1. AMD A8-7670K
If you are an AMD enthusiast (or like rooting for the underdog), these are interesting times. AMD is about to launch a series of processors based on a new architecture (Zen) which will obliterate the current generation of CPUs. So prices are falling accordingly. The A8-7670K remains one of the rare bright spots in AMD’s lineup despite being more than two years old.
It is built on a newer 28nm manufacturing process which
Intel and AMD are the two companies who dominate the PC Processor market. Both of them are around for decades become the main Chip suppliers for the home and business markets.
Both companies have fierce rivalry and they file and counter file court cases against each other all we care about is that they have near identical chip products on the market at the same time as they compete for the fastest chip and share of the market.
The competing products are very close to each other and really only the techies compare the benchmarks before choosing.
Intel Pentium Dual Core Processors
The Intel Pentium processors with Intel dual-core technology deliver great desktop performance, low power enhancements, and multitasking for everyday computing.
Intel i3 Processors (Ivy Bridge)
Intel Core i3 dual core processors provide 4-way multitasking capability, runs at fixed speed ideal for typical tasks and media playback but not games.
Intel i5 Processors
Intel i5 usually quad core but some dual processors deliver the next level of productivity. Mostly the same as i3 but with Intel Turbo Boost Technology, delivers extra speed
A fully functioning, yet compact and lightweight cloud computing system.
Using 10 low-cost, credit-card-sized computers called Raspberry Pi’s, an old winter jacket, three power banks and a small remote touch screen display, Hasan and Khan developed a wearable system that brings all mobile computing solutions together, creating the ultimate smart device. The cloud jacket could make the design of mobile and wearable devices simple, inexpensive and lightweight by allowing users to tap into the resources of the wearable cloud, instead of relying solely on the capabilities of their mobile hardware.
“Currently if you want to have a smart watch, smartphone, an exercise tracker and smart glasses, you have to buy individual expensive devices that aren’t working together,” Hasan said. “Why not have a computational platform with you that can support many forms of mobile and wearable devices? Then all of these capabilities can become really inexpensive.”
The need for more powerful processors and consumer expectations for high-performance applications have caused the design of wearable and mobile devices to be complex and expensive. Someone who wishes to own a smart watch, smart glasses, a smartphone and a wearable health device would have to spend between $2,000 and $3,000 to purchase such devices. The cloud
The use of smartphones and tablet computers during evening hours has previously been associated with sleep disturbances in humans.
The use of blue light emitting devices during evening hours has been shown to interfere with sleep in humans. In a new study from Uppsala University involving 14 young females and males, neuroscientists Christian Benedict and Frida Rångtell sought to investigate the effects of evening reading on a tablet computer on sleep following daytime bright light exposure.
‘Our main finding was that following daytime bright light exposure, evening use of a self-luminous tablet for two hours did not affect sleep in young healthy students’, says Frida Rångtell, first author and PhD student at the Department of Neuroscience at Uppsala University.
‘Our results could suggest that light exposure during the day, e.g. by means of outdoor activities or light interventions in offices, may help combat sleep disturbances associated with evening blue light stimulation. Even if not examined in our study, it must however be kept in mind that utilizing electronic devices for the sake of checking your work e-mails or social network accounts before snoozing may lead to sleep disturbances as a result of emotional arousal’, says senior author Christian Benedict, associate professor at the
The use of algorithms to filter and present information online is increasingly shaping our everyday experience of the real world.
Associate Professor Michele Willson of Curtin University, Perth, Australia looked at particular examples of computer algorithms and the questions they raise about personal agency, changing world views and our complex relationship with technologies.
Algorithms are central to how information and communication are located, retrieved and presented online, for example in Twitter follow recommendations, Facebook newsfeeds and suggested Google map directions. However, they are not objective instructions but assume certain parameters and values, and are in constant flux, with changes made by both humans and machines.
Embedded in complex amalgams of political, technical, cultural and social interactions, algorithms bring about particular ways of seeing the world, reproduce stereotypes, strengthen world views, restrict choices or open previously unidentified possibilities.
As well as shaping what we see online, algorithms are increasingly telling us what we should be seeing, the study argues. For example, an algorithm that claims to spot beauty and tell you which selfies to delete implies we should trust technology more than ourselves to make aesthetic choices. Such algorithms also carry assumptions that beauty can be defined as universal and timeless, and can be easily
How important are software design skills to a programmer? Programmers, in the traditional, and perhaps most widespread, view of the software development process, or others .
The job of the programmer, after all, is to write code. Code is viewed as a “construction” activity, and everyone knows you have to complete the design before beginning construction. The real design work is performed by specialized software designers. Designers create the designs and hand them off to programmers, who turn them into code according to the designer’s specifications. In this view, then, the programmer only needs enough design skills to understand the designs given to him. The programmer’s main job is to master the tools of her trade.
This view, of course, only tells one story, since there is great variety among software development projects. Let’s consider a spectrum of software development “realities.” At one end of the spectrum we have the situation described above. This hand-off based scenario occurs especially on larger, more complex projects, and especially within organizations that have a longstanding traditional software engineering culture. Specialization of function is a key component on these kinds of projects. Analysts specialize in gathering and analyzing requirements, which are handed off to designers
