What you need to know about Bitcoin after the WannaCry Ransomware attack?

After the recent worldwide attack of ransomware, Bitcoin was highlighted in the news again. The harmful software locks the victim’s access to all their files and data and refuses to grant them access unless a ransom is paid in the form of at least $300 in bitcoin. This leaves one wondering what exactly is bitcoin and why do hackers want their payments in this form?

What is bitcoin?

Bitcoin is a type of a digital currency. One can buy dollars or euros with it and also one can trade any other currency. It is stored in an online wallet and through this wallet, one can use bitcoin online and also in the physical world for purchasing services and goods. Bitcoin is also supported by PayPal. Bitcoin also has valuation and it’s price keeps fluctuating up and down, just like any other currency.

What's different about bitcoin?

Usually, while purchasing something online, one uses a credit card or a debit card. This card connects to information about the user, such as the name and the billing address. One can use bitcoin the very same way one uses debit or credit cards and the transactions made are completely anonymous. This can’t be used to personally identify you. Whenever one trades in bitcoin, a private key is used which is associated with the user’s wallet and a code is generated, called an address. This address is then publicly linked with the transaction but no personal details and information are identified. In this way, every bitcoin transaction is recorded and is signed securely in an open ledger that can be viewed and checked by anyone. Thus, bitcoin can be used to protect one’s privacy.

Is this why the WannaCry hackers chose Bitcoin as a form of payment?

Most possibly, yes. Bitcoin has gained its reputation as a technology that can facilitate crime in the news media. Although the identities of users making bitcoin transactions are not revealed, law enforcement can trace these transactions and the movement of bitcoin with the help of the public ledger. Online criminal operations that have used bitcoin, have been successfully prosecuted by the Justice Department.

Law Enforcement and WannaCry

The government is already investigating these attacks. White House homeland security adviser Tom Bossert stated that the process of finding out who is behind the crime, also called as attribution, is a generally tough process in computer attacks. Most of the times, the attackers are not easy to catch hold of as they are beyond the reach of U.S. law enforcement. Their activities are hidden behind multiple layers of security.

Money Collected by the Attackers

According to Quartz, the news site tracking the amount of money in the hackers’ wallet, so far the amount looks to be about $55,000. It’s not a lot of money considering that the European Union Law enforcement agency, Europol, has said that more than 200,000 computer systems have been affected. Still, in recent years, the value of a single bitcoin has seen a steady rise. An all-time high price of $1,830 per bitcoin was seen just hours before the WannaCry attack began to spread. However, after the attack was revealed, the price fell by $200. Looking at how easily hackers can attack with ransomware, acquiring even a handful of bitcoin and keeping a hold of it for sometime can help the cyber-criminals gain a large sum of money.

Construction Begins on Google’s Massive Seattle campus in Amazon’s Backyard

Google’s New Campus – Established by Paul Allen - Vulcan Read Estate

Works has begun on the new campus of Google in Seattle’s South Lake Union neighbourhood, on the outskirts of global headquarters of Amazon. The project is being established by Vulcan Real Estate of Paul Allen and tends to span two whole blocks and would comprise of office space of around 600,000 square feet, together with residential tower on every block with a combined 149 units according to Lori Mason Curran investment strategy director of Vulcan Real Estate.

Commencement of the work had started earlier in the month on the project that had been announced last year which will be reaching completion in early 2019. Vulcan also tends to have an adjacent block which is not a portion of the project of Google. According to Mason Curran, the site is intended for 216 residential units and 161,000 square feet of office space. It is said that Vulcan would not begin this block till it lands a tenant.

The main player for long has been Amazon in South Lake Union. However, the entry of Google in the neighbourhood down the road together with the rapidly growing presence for Facebook should provide plenty of competition for top talent.

Structure – Begin in Phases 2017 - 2019

Presently, Seattle area footprint of Google comprises of offices in the Fremont neighbourhood and the Eastside suburb of Kirkland, Wash. It is uncertain what Google intends to do with its Fremont space when the new Seattle campus seems to be ready. However at the moment, investing in the neighbourhood, Google had signed a deal, earlier this year to sublease the former sound Mind & Body Gym space in 2014 that Tableau had altered into around 50,000 square feet of tech office space, for its engineering team.

The structure would begin in phases from 2017 and would complete in 2019. According to an official from Vulcan, Google has agreed to leases which would be lasting 14 to 16 years, a new sign of its long-term commitment to the Seattle region. Joined with the recently expanded offices in Kirkland, Wash of Google, the technology giant would be approaching 1 million square feet in the area with this latest space. Presently Google tends to have over 1,900 employees in Washington State, in offices in Seattle and Kirkland.

South Lake Union – Thriving Hub

Google would be moving from its present location in Seattle’s Fremont neighbourhood, wherein the space had been constrained in recent years considering the rapid expansion of Tableau Software together with the other technology companies. Clyde McQueen, site Lead for Google Seattle had mentioned in a news release that South Lake Union is a thriving hub and they were excited for the new space. They loved being in the Fremont neighbourhood though would need more breathing space.

They are yet to catch a view of Lake Union, from the new location. Besides providing a bigger footprint for Google in the city, the news is prominent since Amazon is not the one taking the building and Vulcan had established the online retailer’s prevailing campus in the South Lake Union neighbourhood. More focus has been done by Amazon on its expansion in the neighbourhood towards the south where it is rolling its own three block campus on the northern outskirts of downtown Seattle.

A Google Engineer Recreated a DSLR Photo Using a Nexus 6P with Absolute Perfection

Create Image Utilising Nexus 6P

Smartphone cameras have been enhanced beyond our imaginations and from the rough VGA cameras which the earlier phones featured, to the updated Dual Cameras lots that tend to replicate DSLR type portrait shots with perfections, smartphone photography had progressed to great extent.

However there seems to be one segment wherein smartphones are unable to compare up to the DSLRs low light photography and Google has plans of changing it. OEMs tend to advertise low-light photography as a feature in their phone cameras though usually it is more of a trick. An engineer Florian Kainz working on Gcam team of Google, the team behind the legendary camera of the Google Pixel had been challenged by his colleague to develop a night shot of the Golden Gate Bridge which had originally been shot by a DSLR utilising a smartphone camera.

He had accepted the challenge and had managed in creating the image utilising the Nexus 6P together with some post-processing and created an image using smartphone providing us a glimpse of what Google could do in making night-time outdoor photography a real thing with the support of smartphones.

Technique for Shooting Milky Way – Google Pixel

Using a technique he was capable of shooting the Milky Way utilising the Google Pixel from the Californian coast where the nights tend to get very dark and the stars are said to be the only source of light on nights when the moon is not in sight.

But at 9 to 10 megapixels, the subsequent photos did not seem to be as high quality as a DSLR, though the details seemed to be there. With the results of the Pixel together with the Nexus 6P, it is clear that the final frontier of smartphone photography is on the threshold of being penetrated.

Software has been developed by OEM in order to process the images internally, with all the additions together with the subtractions as well as the averaging of the multiple photos to make night point and shoot photography utilising a smartphone, a reality. But one can’t take photos yet the same way with your smartphone and the Google Pixel tends to come the nearest in taking such images though not close enough.

HDR+ Feature

Google is said to utilise the HDR+ feature that swiftly takes 10 short exposure shots and averages them to form an individual image to eliminate blur and noise at the time of collecting adequate light for good photos at practically low-levels though it will still tend to be impractical in very low-light, moonlight landscapes for example, or starlight photos.

To achieve the image, Kainz had installed a custom Android app which enabled him to set the ISO, shutter speed and focus manually. He also utilised a tripod to keep the phone steady. The custom app was to eliminate the maximum 4-second exposure time for taking longer exposure shots in order to lessen the ISO setting and thus reduce the noise.

When the shutter button is pressed, the app tends to wait a few seconds and then takes up to 64 frames with the selected exposure and ISO settings. Thereafter it saves the frames as DNG file wherein these are later exported to a PC to post-process into one.

What is Spectrum Why is It a Big Deal for Cell Phone Companies?

Spectrum Best Opportunities for Wireless Companies

The most recent government action regarding radio airwaves would be affecting the prospect of the wireless industry and services. We need to be aware on the updates. Recently was the start of the Federal Communication Commissions’ Incentive Auction that had taken valuable spectrum away from TV broadcasters to sell it to companies who would offer wireless service.

This specific band of spectrum is said to be priced extremely and industry insiders have named it `beachfront property’, since it tends to operate at lower frequency. This means that it has the potential of running across greater distances going through walls for greater coverage. This is the reason why this auction needs the attention of the viewer. It represents one of the best opportunities for wireless companies in getting more spectrums which is how things get conveyed to the phone from videos to work emails.

 Moreover it could also remodel the wireless industry, providing smaller carriers with an opportunity of offering the similar, robust nationwide coverage which Verizon Wireless and AT&T tend to provide. Overall, they seem to control over 70% of the wireless market of US. Further than the two big, T-Mobile, satellite TV provider Dish Network and cable giant Comcast are other large players who intend joining in the auction.

Spectrum – Range of Radio Frequencies

Spectrum is said to be the range of radio frequencies which are utilised in transmitting sound, data as well as video to TVs or smartphones. These are the airwaves which had ignited Beatlemania in December 1963 when radio stations had started playing `I Want to Hold your Hand’.

Presently it tends to deliver `Games of Thrones’ to your phone through the HBO Co app. Extra spectrum would mean quicker and more-reliable wireless service. Spectrum is said to be a restricted resource which is controlled for the greater part by the US government. Companies could have it if they are inclined in participating in auctions, acquire a company with spectrum holding or purchase licenses from one another in a secondary market.

To manage the ever-increasing volume of data traffic that is created over phones, tablets, cars together with the other gadget as well as machines, additional spectrum is essential. The 600 MHz band, the spectrum which has taken hold in the auction, has traditionally been utilised in transmitting TV signals and is probably the last time the government would be capable of auctioning off such spectrum.

Lack Significant Volume of Low-Bank Spectrum

Low-band spectrum tends to function consistently indoor and over great distances and could be helpful to carriers in keeping up with the increasing demands for coverage on the part of the customer.

The two big winners in the last auction of low-band spectrum in 2008- AT&T and Verizon have erected the foundation of their 4G LTE networks on low-band 700 MHz spectrum which was another sliver of spectrum that had once been utilised in broadcasting TV. The third largest wireless provider of the nation, T-Mobile has been making attempts in assembling an identical set as assets for its own network though for the most part, T-Mobile is said to lack significant volume of low-band spectrum.

Incentive Auction is actually two auctions in one and there is a reverse auction which would permit TV broadcaster in selling their airwaves back to the government. A forward auction would be following in the next few months by which the government would be selling these same airwaves to wireless companies. Broadcasters would be getting a cut of the proceeds in exchange for giving up their spectrum.

Largest & Complex Auction

This auction is said to be the largest and the most complex auction ever run by the FCC. Dish Network, the Satellite TV provider is anticipated to bid in the modern FCC spectrum auction though it is not certain if the company would be as aggressive as it had been in the AWS-3 auction, last year when it had paid $10 billion.

Estimates had recommended that the auction could generate around $60 billion though several in the industry were of the opinion that the price is not accurate considering the constrained budgets of the carriers. Eight years back, the 700MHz had raised $19.6 billion and last year AWS-3 auction had collected in a record setting of $45 billion. AT&T, Verizon and T-Mobile would probably purchase the bulk of available spectrum in this auction since the FCC is aware how critical low-bank spectrum is in forming a company which could oppose AT&T and Verizon.

 The agency has fixed out a sliver particularly for smaller players such as T-Mobile together with some rural operators in bidding on without facing the deep pockets of AT&T together with Verizon. Dish is said to be another wild card in this auction that had been steadily progressing up a conflict chest of spectrum. It is not certain what Dish intends to do with the spectrum which is own already and the licenses it would probably pick in this auction.

T-Mobile Tougher Substitute to AT&T

There is a possibility that the company would be looking for a partner or would be developing a fixed wireless service which would serve as a substitute broadband connection to DSL or cable. Comcast also tends to bid in the auction as long as a competitor in the auction to T-Mobile for spectrum reserve for smaller operators. The provider has developed an extensive wireless network utilising Wi-Fi technology and would ultimately partner along with a cellular operator in building a network to rival with traditional wireless carrier.

 Comcast has given no indication on how it intends to utilise the spectrum. It could utilise the licenses in building its own network though there is a possibility that Comcast would be using the licenses as a bargaining chip while dealing with traditional carriers. Particularly absent from the auction is Sprint, the fourth ranked carrier. Based on how the auction tends to turn out, T-Mobile would probably end as a big winner.

That means that for the average consumer, T-Mobile can be a tougher substitute to AT&T and Verizon. Usually, T-Mobile tends to have frail signals beyond major cities though the spectrum from this auction would be helpful in covering additionalregions of US particularly those in the suburbs as well as rural regions.

Google's AI Chips Will Have A Tough Time Competing With Nvidia

Nvidia's chief played down the challenge from the Google AI chip

Nvidia has shared many of its forthcoming on the bringing of omnipotent graphics chips used for the wonderful Technology of AI, thus it was not a outstanding day for the organization as Google had famed couple of weeks ago that it had well-stacked its own Artificial Intelligence chip for use in data fractional monetary unit.

The profound Google's TPU Technology, has been premeditated generally for deep learning, a division of the AI software Technology train themselves to decode them to make the world finer thus that it can acknowledge things or read the spoken language.

TPUs Technology have been distributed on Google for over a year, for lookup comprehensive and navigation on Google maps. They bring out "a ratio finer carrying into action per watt machine learning" compared to different derivatives, according to Google.

The awful tidings for Nvidia's Technology might be that its spick-and-span Pascal micro architecture is planned with machine learning in mind. Subsequently dropping out of the smartphone industry, the organization with magnificent Technology is sensing for AI development, gaming as well as Vitual Reality.

For the initiative, he said, the Technology of profound learning has two prospects to it - upbringing and illation – as well as GPUs are still overmuch finer on the upbringing, reported by Huang. Grooming Technology affects an algorithmic program with immense magnitude of information to present, devising it finer to acknowledge something while logical thinking is when the rule employs what it has enlightened to an unbeknown input.

"Upbringing is billions more complex that logical thinking," he said, as well as grooming is where Nvidia's GPUs stand out. TPU Technology of Google, but then, is "just for logical thinking," Huang said. A formula upbringing can take months, he said, while ofttimes illation come about in seconds fragmental parts.

In addition to this distinction, he noted that of the many companies who do inference need not have their own processor Technology.

"For organizations that manufacture their own logical thinking chips, that's not a difficulty for us, we re pleased by that," Huang said. "Merely there are millions of knobs in the Hyper-scale data fractional monetary units of organizations that do not manufacture their own TPUs. The best solution we can suggest for them is Pascal."

The Google improved its own chip should not be a ample surprisal. The engineering can be a combative vantage for big online service providers, as well as giants like Google, FB and Microsoft already plan their own servers. Scheming a processor is the succeeding coherent measure, albeit a challenge.

Whether development of the Google's TPU has affected its other chip purchases.

"We're still literally buying tons of CPUs and GPUs," said a Google engineer The Wall Street Journal.
Interim, Nvidias Huang, as some other in the industriousness hoped-for deep learning and AI to get along omnipresent. The last decade were the period of time of the mobile cloud, he said, as well as we are at present in the epoch of artificial intelligence. Companies need to healthier interpret the multitude of data they roll up, and that come about through AI.
