US Researchers Find A Way to Make Internet Access Cheaper, Faster

Recently, US researchers have found a way to increase the speed of internet (data traveling) over a fiber optic network. It is expected that this technology will adopted commercial to provide cheaper and faster internet. According to Nikola Alic, a data scientist at Qualcomm Institute, which is part of the University of California at San Diego, this technique will take the couple of years to make a meaningful impact, but it’s all about implementation process and determination of the technical community. The more he added that whenever more you struggle the much faster you sink because it’s like quicksand.

US based researchers have found the way which is more significant to improve the performance of fiber networks as it could be benefit for both such as; ISP (Internet Service Providers) and consumers. The researchers have found a way to manage the distortion in internet network whenever you try to add power in it. It allows data to travel for longer distances before being reconditioned by electronic regenerator.

However; it’s clear that these findings will eliminate the need of electronic regenerators. These fiber optic cables are not only able to carry information or data for long distance, but also they don’t need power to supply data. Information and data in fiber optic cables get degrades with the distance travel and whenever you will try to increase the speed of internet at which data or information is traveling after getting boost from power in the network, so degradation gets worse.

The main concern with repeaters is that they should be applied anywhere from 80 to 200 data channels, but it could be highly power consuming as well as much expensive. However; to reduce the numbers of repeaters in the network, researchers have used the frequency combs of wideband to make sure that signal distortion which also known as the crosstalk.

Crosstalk occurs in the fiber to convert it into the original state after while arriving at its final destination. We all are aware that crosstalk was not random as it governed by high strict physical laws, but whenever we will look into the lab, it will appeared as the random which is still mystery, explained Alic.

According to Doug Brake, who is telecom policy analyst at The Information Technology & Innovation Foundation, it affects the way of sending the information over the fiber optic networks, but it is not a limitation factor while building the infrastructure at the last stage. In the whole process eventually, researchers have discovered the frequency variations in the entire communication channel, which need to tune at the source.

To produce some meaningful result in the lab researcher were able to retrieve the information after traveling 7,400 miles or 12,000 kilometers through fiber optic cables as well as standard amplifiers. According to cyber experts, this technology is meaningful and attractive for new ISP players such as; Google as they are adopting aggressive marketing strategies and technologies to capture the major market share.

Algorithm Accounts For Uncertainty To Enable More Accurate Modeling

Data Integration Algorithm – Improve Modelling Accuracy

Parametric uncertainty is a remarkable error source in modelling physical systems where the values of model parameters characterizing the system are not clear due to inadequate knowledge or limited data. In this case, data integration algorithm could improve modelling accuracy by calculatingand reducing this uncertainty. Nevertheless these algorithms frequently need a huge number of repetitive model evaluations, incurring important computational resource costs.

With regards to this issue, PNNL’s Dr Weixuan Li together with Professor Guang Lin from Purdue University proposed an adaptive position sampling algorithm which could alleviate the burden produced by computationally demanding models and in three of these test cases, they demonstrated the algorithm could effectively arrest the complex posterior parametric uncertainties for the precise problems examined while at the same time enhance the computational efficiency. With great headway in modern computers, numerical models are being used regularly for the purpose of stimulating physical system behaviours in scientific field which ranges from climate to chemistry and materials to biology, several of them within DOE’s serious mission zones.

Several Potential Applications

However, parametric uncertainty often tends to ascend in these models due to insufficient knowledge of the system being stimulated, resulting in models which diverge from reality. The algorithms created in this study offers active means to assume model parameters from any direct and/or indirect measurement data through uncertainty quantification, thereby improving model accuracy. This algorithm seems to have several potential applications for instance; it can be used to estimate the location not known, of an underground contaminant source as well as to improve that accuracy of the model which envisages how the groundwater tends to get affected by this source. Two of the key systems which has been implemented in this algorithm are

•  A Gaussian mixture – GM model adaptively built in order to capture the distribution of uncertain parameters 
•  A mixture of polynomial chaos – PC expansions which are built as a surrogate model in order to relieve the computational burden caused by forward model evaluation. These systems provide the algorithm with great flexibility in handling multimodal distributions and powerfully nonlinear models while at the same time, keeping the computational costs at the lowest level.

Worked Well with Small Number of Uncertain Parameters

Though the algorithm worked well for problem connecting with small number of uncertain parameters, constant research with regards to problems linking to bigger number of uncertain parameters indicated that it is better to re-parameterize the issue or represent it with lesser parameters rather than to directly illustrate from the high dimensional probability density function. Besides this it also involves implementing the algorithm within a consecutive importance sampling outline for successive data integration issues. One of the example problems comprises of dynamic state estimation of power grid system.

The New Microsoft Edge Browser Logo

Microsoft’s New Edge Browser – Break from Internet Explorer

Microsoft’s new Edge browser was likely to mark a break from Internet Explorer and recently the company unveiled Edge’s new logo and it seems incredibly similar to the earlier IE logo but a little sharper. Microsoft Edge, the new name for web browser will be included in Windows 10 and has a familiar look for users of Microsoft’s current browser – Internet Explorer. Since 1996, the popular blue `e’ with the orbital rings round it symbolized Microsoft’s Internet Explorer browser and IE 3 seemed to be the first version to sport the logo.

 However in recentyears, the `e’ seemed to become identical with bugs, out-dated technology and security problems. When Joe Belfiore, Microsoft operating systems chief, unveiled Edge in April, he noted that Edge would have an `e’ icon though he said that it `now has a completely different and better meaning than it has for a while’. Edge is an improvement over IE and much trimmer than IE without the various menu choices and bells and whistles. It has a clean, modern look just like Google’s GOOGL.Tech30, Chrome browser. One can mark-up websites by using Edge which integrates some of the powers of Microsoft’s’ digital assistant – Cortana.

Integrating on Improved Features 

Retaining the Edge logo is consistent with the Microsoft in considering Windows 10 and with the updated operating system set to be unveiled on July 29; Microsoft is making attempts in creating the software, familiar to users who have been using Windows for a long time and are alarmed by the radical design change of Windows 8. However the company is also integrating on improved features which would make Windows 10 much more than just an `everything old is new again’, operating system.

The new Edge loge seems to be an improvement over the temporary logo that Microsoft had given its new browser prior to making a decision on its official name. When Edge had been known as `Project Spartan’, its logo looked like something the World Bank’s logo crossed with Toyota’s symbol. Microsoft Edge is the only browser which enables the user to take notes, doodle, write and directly highlight on webpages, The web is the palette where one can add a few secret ingredients to a recipe right on the screen while sharing with friends, collaborate on a new project with co-workers, etc.

Default Browser on PC/Mobile Device Editions of Windows 10

Microsoft Edge would be serving as the default browser on the PC as well as the mobile device editions of windows 10, replacing Internet Explorer 11 and Internet Explorer Mobile. It would be utilising a new layout engine known as EdgeHTML which has branched from Trident, designed for inter-operability with the current web.

The updated `Edge’ engine would be used across Windows 10 by default and would support the legacy MSHTML engine for backwards compatibility though late,r backed down revealing that because of strong feedback, Edge would be hosting the new engine entirely while Internet Explorer would be hosting the legacy engine completely. Edge does not intend to support legacy technologies like ActiveX and Browser Helper Objects, but instead will utilise an extension system.

 Availability of Internet Explorer 11 would be possible together with Edge on Windows 10 for the purpose of compatibility and will remain almost identical to the Windows 8.1 version and will not use the Edge engine as announced earlier.

IBM Discloses Working Version of a Much Higher-Capacity Chip

IBM has taken the technology industry with surprise through its announcement of successfully developing working versions of ultradense computer chips. These chips are said to possess four times the capacity of today’s most powerful chips.

This announcement was essentially made on behalf of an international consortium led by IBM. IBM has invested $3 billion in an exclusive private public partnership in New York’s Hudson Valley with New York State, Samsung, GlobalFoundries and equipment vendors to manufacture advanced computer chips.

New Generation Of Chip In Development

It should be noted that each generation of chip is defined by the minimum size of fundamental components, which play role in switch current at nanosecond intervals. In modern times technology industry is actively working towards making a commercial transition from 14 nanometer to 10 nanometer manufacturing. Each generation helps in achieving 50 per cent reduction in the amount of area required for circuitry. IBM has affirmed its new chip which is still in research phase will be based on the shirking the area of semiconductor as much as possible by 2018.

IBM currently has working samples of chips with just seven nanometer transistors. It has been able to develop such sizes due to use of advanced silicon-gremanium instead of relying on pure silicon in key regions of chip. This material has made it possible to develop faster transistor switching with low power requirements, which is an added advantage. Given the smaller size of the transistors, it is highly possible to build microprocessors with not more than 20 billion transistors.

IBM Brings Focus Back On Itself As Revolutionary Chip Manufacturer

IBM has already shed a certain amount of its computer and semiconductor manufacturing capacity in the recent past. But this announcement shows that IBM is still interested in backing the technology manufacturing base with its efficient research facilities. Rather than being the horse power in building and providing chips to the companies it will act as a pioneer in unearthing advanced technological solutions for others. IBM will have to grapple with shift to use extreme ultraviolet (EUV) light for etching patterns on the chips at a resolution which approaches the diameter of an individual atom.

IBM will be licensing the technology to a variety of manufactures and most importantly, GlobalFoundries which is owned by the Emirate of Abu Dhabi will be making these chips for some big companies which includes, Qualcomm, Broadcom and others. It is yet to been whether semiconductor industry thinks on using silicon-gremanium as the best option or not.

IBM Refuses To Confirm Commercial Manufacturing

IBM has simply declined whether it will begin commercial manufacturing of this technology or not. Another ambitious company named Taiwan Semiconductor Manufacturing Company had given green lights to its plans to begin production of seven nanometer chips in 2017.

Given the precision required for using EUV light to keep the high capacity usage of chips optimum might be a concern in the commercial manufacturing operations. The goal of IBM here is to create next generation circuits, which offer higher capacity with reduced area, and most probably with current advancements and right amount of further research this technology will be introduced next year.

Hackers Unearth Major Security Flaw That Affects Adobe Flash Player

A major gaping hole is found in the popular Adobe Flash Player software used for watching videos online on a global scale. This flaw allows the attackers to take control of user’s system once they visit any malicious website.

Hackers Team which is known to create surveillance software for governmental agencies had stumbled upon this flaw when 400 GB of data was stolen from it over the weekend. Adobe had cleared all the speculations surrounding the emergence of this serious flaw and it had promised to make a fix available to all the users by Wednesday.

All You Need To Know About The Flaw In Flash Player

This serious flaw is present in the Adobe Flash Player 18.0.0.194 and its earlier versions, which were released for all the major OS like Windows, Mac and Linux. Adobe stresses on the fact that this flaw can be used to cause a sudden crash and act as a backdoor for the attackers to take control of affected system.

Hacking Team had described this bug as a fascinating bug, which had come to light in as many as four years of successful running of Flash player. The severity of this flaw is extremely high and some of the hackers are already utilizing it for a long time to create undue nuisance for the users with affected systems. The internal documents also stress on the point that it can be used as a weapon on mass scale to cause considerable loss of information and high-jacking of systems on a larger scale. Until a fix or security update is provided by the Adobe it will be wise to disable the Flash Player completely in the browsers to avoid further damages.

Hacking Teams Cautions Windows Users

The data released by the Hacking Team also reveals about vulnerability in the Adobe font drivers in Windows. The flaw in Flash Player has high severity rate in both 32 and 64 bits versions of Windows OS ranging from the order XP to latest 8.1. Windows computer is at greater risk of losing control to the hackers with the presence of this flaw. For successful taking control a hacker will have to rely on other vulnerability of font driver. Microsoft is quick to give heed on this situation and they are actively working on bringing a security fix for its users.

Hackers Are Already Exploiting This Flaw

Hackers Team got a wind of this flaw after a mysterious hacker going by the name PhineasFisher started exploiting this flaw. He had already created immense troubles for many companies being serviced by Hackers Team which includes even some governmental institutions.

The detailed report furnished by Hackers Team states that its RCS surveillance software possess capabilities for monitoring activities on Skype, Gmail, Facebook and Outlook.com along with cryptocurrencies transactions. This can be helpful for companies and its clients in keeping a keen eye upon its employees. However European parliament is seriously debating upon the legitimacy of any such software being used by a governmental organization to snoop upon its citizens.
