Amazon founder Jeff Bezos becomes world's richest man as the company's stock price soars



Amazon founder Jeff Bezos has overtaken Bill Gates to become the world's richest person, worth $91.4bn (£70bn).A 2.5% rise in Amazon shares on Thursday means Mr Bezos's wealth has now eclipsed the Microsoft co-founder by $1.4bn, according to Forbes.Mr Bezos, 53, owns about 17% of the shares in Amazon, whose value has now exceeded $500bn.The online retailer reports second quarter results after Wall Street closes on Thursday.For the first three months of this year Amazon's sales jumped 23% to $35.7bn. The company expects a rise of 16% to 24% for the quarter to June.In recent years Mr Bezos has focused on his Blue Origin space rocket business and the Washington Post newspaper, which he bought in 2013.Soaring technology stocks have fuelled huge growth in the worth of entrepreneurs such as Mr Bezos and Facebook founder Mark Zuckberberg, 33, who is now worth $72.6bn according to Forbes.Just over two decades ago Jeff Bezos started selling books online from his garage. Today, the Amazon CEO is the richest person on Earth.Bezos's net worth topped $90 billion on Thursday, allowing the Amazon founder and CEO to narrowly dethrone Microsoft (MSFT, Tech30) co-founder Bill Gates as the richest man in the world, according to Forbes and Bloomberg. If Amazon stock holds steady through trading Thursday, Bezos will officially bump Gates, who has been No. 1 since 2013, from the the Bloomberg Billionaires Index.Bezos has been hailed as the smartest guy in business for turning a bookselling platform into a disruptive force that has flipped traditional retail on its head.His world's-richest-man milestone was made possible because of Amazon (AMZN, Tech30)'s surging stock price. The e-commerce juggernaut's market value surpassed $500 billion this week for the first time ever.The vast majority of the Bezos fortune is tied up in Amazon stock, of which the CEO owns nearly 17%. That stake alone is worth $83 billion, meaning Bezos could just as quickly lose his new title as the world's richest man should Amazon's stock decline, or Microsoft's value rise.In recent years, Bezos's fortune has whizzed past that of legendary investor Warren Buffett, Spanish retail magnate Amancio Ortega and Mexican tycoon Carlos Slim. Bezos added more than $24 billion in net worth since January 2017, according to Bloomberg.Bezos founded Amazon in the mid-1990s from a garage, originally as an online bookseller. But over the years Bezos has deftly steered Amazon into hardware, cloud services, music and streaming shows. All along the way, Amazon used technology and sheer force to ruthlessly cut prices. Customers in turn have flocked to Amazon, which raked in a stunning $136 billion in sales last year alone.The Amazon boss's bold vision was on full display again in June when he shocked Wall Street and the business world with a $13.7 billion purchase of Whole Foods (WFM). The surprise deal instantly made Amazon a major bricks-and-mortar player and sent a wave of fear through traditional grocery stores and food companies.Bezos has used his fortune to purchase The Washington Post in 2013 and launch his own rocket company, Blue Origin.

This Standalone VR headset by Games Face works with Android, OculusRift, HTC Vive and SteamVR

This small but rising startup is working on creating an ultimate VR experience , enabling you to use the device while you’re moving, and once you’re home – you can connect it to the PC. Unlike any other product on the market, there is no ‘collision of worlds’. HTC Vive and Oculus Rift are experiences that require a PC and are intended for internal use, while mobile headsets like the Samsung’s GearVR work wherever you are. With this concept, GameFace Labs wants to cover both angles.
Content is King. This has been the statement the CEO since he involved with this 360VR thing a few years ago. So when we hear of a company that wants to UNITE all of the VR content under one roof, or one VR Headset if you prefer, we don’t merely take note. We stand up and applaud.
 GameFace Labs is not exactly a new-comer. The good folks at Engadget gave them great coverage at CES 2014, where they were demonstrating their first prototype, the EP-1. The product has evolved since, in a major way.

GameFace CEO says that it “has a unique technology that lets GameFace download content up to 100 times faster than traditional downloading methods, which enables instant-gratification VR content with zero latency or atleat less than 10 milliseconds. Everything is cloud-delivered but locally rendered for a latency-free VR cloud-gaming experience. It even has a built-in fan that promises to keep things nice and cool during operation.”

Sounds enticing, right?! But wait… There’s more… Check out the features listed below…

Features:

Android OS (Custom Nougat & Daydream Ready)
2x 90Hz 2,560 x 1,440 display panels (custom made by Samsung)
120° Field of View
No need for PC or a specific Smartphone
Portability (Untethered VR, hooray!)
7+ Hours of Battery Life
nVidia Tegra SoC “more Powerful than 2x Xbox 360s strapped to your face” (lol!)
Valve SteamVR (Lighthouse tracking in Android & PC environments)
AR Ready: Stereo 3D cameras for hand-tracking, AR & holographic experiences
The headset is surprisingly lightweight for a unit that can work with VR Content from Cardboard apps to Oculus/Vive.

“I think one of the biggest holdbacks for VR is content,” says Mason CEO. “The fact is that the people who are pushing the content, they’re not triple-A studios, they’re the indies. These are the guys who can’t afford to buy $10,000 to $15,000 worth of six to seven different headsets just so they can release $5 to $10 apps on six different stores. This is hampering development quite significantly.”

Info for Developers:

Reserve one of two variants of the EP1 headset, either the GF-DD which offers support for the Daydream platform specifically, and the GF-LD which includes support for Lighthouse positional tracking.
The GF-DD carries a price tag of $500 USD, whereas the GF-LD costs around $700 USD.
Pricing is subject to change, we suggest you pounce on this.

So what is the End Game for GameFaceLabs? “What we’re trying to do is build one headset that is trying to unify a rapidly fragmenting industry,” Mason says. “What we really are is a VR-enabling company.”

Amazon launches a Social E-Commerce Network SPARK for iOS

Amazon.com Inc (AMZN.O) has launched a social feature called Spark that allows members to showcase and purchase products on its platforms, the retail giant's first clear move into the world of social media.

Spark, which is currently only available for Amazon's premium paying Prime members, encourages users to share photos and videos, just like popular social media platforms Instagram and Pinterest. The new feature publicly launched on Tuesday for use on mobile devices that use Apple's (AAPL.O) iOS operating system.

Spark users can tag products on their posts that are available on Amazon and anyone browsing the feeds can instantly find and purchase them on the platform. Users can also respond to posts with "smiles," equivalent to Facebook's "likes."

"We created Spark to allow customers to discover - and shop - stories and ideas from a community that likes what they like," said an Amazon spokeswoman.

"When customers first visit Spark, they select at least five interests they'd like to follow and we'll create a feed of relevant content contributed by others. Customers shop their feed by tapping on product links or photos with the shopping bag icon."

Amazon has also invited publishers including paid influencers and bloggers to post on Spark. Their posts are identified with a sponsored hashtag.

Many Amazon users on social media called the service a cross between Instagram and Pinterest with a touch of e-commerce.

Brand strategist Jill Richardson‏ (@jillfran8) said: "Been messing with #AmazonSpark all morning and I am LIVING. It's like Pinterest, Instagram, and my credit card had a baby and it's beautiful."

Python at the top of Programming Languages in 2017 Focusing on Jobs

While the default IEEE Spectrum ranking in the Top Programming Languages interactive gives a good aggregate signal of language popularity, here we are taking a deep dive into the metrics related to job demand. Two of our data sources, Dice and CareerBuilder, measure job openings for the languages included in the interactive, and consequently we have a preset for “Jobs” that weighs the rankings heavily toward those metrics. So, if you want to build up your tech chops before looking for a programming job, what languages should you focus on?

Although Python has moved to the top of the default Spectrum ranking, if we instead go purely by the volume of openings that mention a language, we find that C beats Python by a ratio of 3.5 to 1, or about 19,300 job openings versus 5,400 across Dice and CareerBuilder combined. The Swiss army knife of database languages, SQL, is also highly in demand (15,400 openings), as are Web technologies like JavaScript (9,300 openings), HTML (7,000 openings), ASP.NET (2,700 openings), and PHP (2,400 openings). R, the increasingly indispensable language for data scientists, saw its zenith in 2016 but had some light contraction in 2017, shedding about 12 percent, to 353 openings. (As a caveat, we should note these numbers reflect job openings as of mid-June 2017, indexed for a 30-day window.)

In the mobile coding space, one of the clearest trends in the default ranking is the rise of Swift at the cost of Objective-C. We can see this in the jobs numbers too: openings for Objective-C shrank by slightly more than 19 percent, whereas those for Swift rose by almost 19 percent. And for the first time, there were more openings for Swift (439 openings) than for Objective-C (394 openings).

There are some significant changes further down the job rankings that are worth keeping an eye on too, even though the absolute number of job advertisements that cite these language is still relatively small. Both CUDA, a general-purpose language for coding GPUs, and Rust, which would feel familiar to most C / C++ programmers, fall into this category. Since 2016, CUDA has moved up four spots to 23 in the Jobs ranking, while Rust moved up a solid 10 positions to 25. Still, the absolute number of job openings was just 40 for CUDA and 23 for Rust. These are niche languages still, but Rust is growing quickly—going from being used in 10,900 new GitHub repositories in 2016 to almost 17,100 in 2017.

This article wouldn’t be complete without mentioning some of the losers in the programming language jobs calculus. Once a dominant Web programming language, Ruby is still used widely but it is slipping; the number of job openings for Ruby shrank by a full third since 2016, to about 1,600. We aren’t the first to report the slump in popularity of Ruby, and it’s far from dead, but this will be one to keep an eye on in the future as coders may already be shifting to alternatives like Python and Go. Demand for other languages like Clojure, Haskell, and Visual Basic is also on the wane. When we started the rankings in 2014, ActionScript still clocked 87 job openings, but in 2017 it continues the downward spiral, with only 20 openings, and it’s unlikely to make the Top Programming Languages at all next year. RIP, ActionScript.

Google redesigned mobile search app will have 'feed' like Facebook but personalized only for the readers interests


Google on Wednesday announced an overhaul of its search app on mobile phones to include a personalized feed of links about hobbies, travel, sports and other topics, a move that puts the search company into more direct competition with social networks such as Facebook.
Google, the world's largest search engine and a unit of Alphabet Inc (GOOGL.O), said the changes would begin rolling out in the United States on Wednesday and other countries in the coming weeks.
The new offering is called "Google Feed," a name that may conjure comparisons to Facebook's "News Feed," a feature on Facebook used to browse updates from friends, family and other sources.
Google said, however, that it was not trying to duplicate Facebook Inc (FB.O), the world's largest social network. Instead, the company said it wanted to create another place to see a stream of relevant search results.
"This feed is really about your interests ... It's not really about what your friends are interested in," Ben Gomes, a Google vice president for engineering, said in a briefing with reporters.
Typical updates might include a link to a website with tips about an upcoming vacation spot, or a link to a page about cycling or another hobby, the company said.
Facebook and Google are jockeying for attention online and by extension, for advertising revenue based on those eyeballs. The two Silicon Valley companies are expected to take in some 50 percent of overall online ad spending in 2018, according to research firm eMarketer.
There were no immediate plans to include advertising in Google Feed, Gomes said.
Google Feed will suggest links based on a user's Google search history as well as data from other Google services, such as YouTube, Gmail and Google Calendar, the company said.
In addition to putting Google Feed on mobile apps, the company is looking at attaching it to web browsers in some form, Shashi Thakur, a second Google vice president for engineering, said during the briefing.

The Optical Wireless Communication Li-Fi which is 100 times faster than WiFi is the Future Broadband Internet


5G Networks could be the next thing in the wireless communication systems as projected in the last Embedded world in Manchester but it could still not be the only next generation wireless communication system emerging as perhaps we can not do without light in this trend.

 The problem with conventional WiFi is that can become extremely irritating especially when too many connections get logged on to the same hotspot. That’s just an inherent fault of WiFi whose protocols share the bandwidth even if that ultimately means no user gets satisfied.

Increasing penetration of smartphones coupled with high demand for mapping portals is expected to stimulate the market for photodetectors components in communication systems. Increasing demand for real-time traffic updates is anticipated to foster the demand for Li-Fi over the period. Up-gradation of prevailing lighting system to communication system might act as a factor for adoption of this technology. However, lack of infrastructure for wireless technology in developing countries is expected to hinder the growth of light fidelity market.
The light fidelity market is classified on the basis of components into photodetectors, LED and microcontrollers. The LED-based light fidelity device can generate the string of binary numbers by switching it on and off and by using the mixture of red, blue and green LEDs the data can be encoded in light by confirming the flickering rate to alter the light frequency. The component transmits the data through the different part of the spectrum. The technological improvements in LED have given a solution by using light for high-speed wireless communication. Photodetectors such as the photodiode are used in detecting and sensing images in the transmitted signal. The demand for image sensing and detecting is increasing owing to its uses in different sectors which are expected to boost the demand for photodetectors in the forecast period. Microcontrollers modulate the data using modulation techniques such as pulse width modulation.
The idea of supporting wireless communication through lights came as a result of this WiFi flaw. LiFi has proved capable of sending data at speeds of up to 1GBps, around 100 times faster than most current Wi-Fi connections. 
The future may soon consist of LED light bulbs connected to a wireless mesh network bringing high-density connections to residential areas and eliminating wireless communication dead zones.
Visible Light Communication (VLC) is not a new technology. In fact, it is quite old. Its history can be traced back in the 1800s with Alexander Graham Bell’s photophone, which used modulated sunlight to transmit speech. VLC is the transfer of information through the use of the visible light portion of the electromagnetic spectrum.
LiFi, one subset of the optical wireless communication technologies, uses VLC between 400 and 800 THz—much higher than most used radio frequencies. A majority of people are probably more familiar with the lower end of the RF spectrum that supports WiFi—2.4GHz and 5GHz.
Devices equipped with special Light Emitting Diodes (LED) can wirelessly send and receive data 100 times faster than WiFi. In a perfect lab environment, LED communication can reach speeds of 224Gbps. The LED bulbs are dipped and dimmed, up and down, at extremely high speeds not visible to the human eye, contrary to the “visible light spectrum” description. Then, another device with a photodetector reads and converts that light into electrical signal.
LiFi’s strengths make it a highly convincing and worthy investment. The technology’s throughput reaches speeds never thought possible, and its wider bands support more users than WiFi.
However, it has weaknesses, too. Due to its higher frequency, its range is shorter and the area it can cover is smaller. Using LiFi would mean using more transmitters, which increases deployment cost. Because VLC system needs light to communicate, it requires near line-of-sight communication. Devices don’t necessarily need to see each other to exchange data because light can bounce off objects but the waves cannot penetrate walls. Although LiFi’s narrow coverage is a disadvantage, it also offers a security benefit. With shorter range, the footprint is easier to control, and wireless hacks can be avoided.
Will LiFi replace WiFi in the future? Probably not. But both technology can supplement each other. LiFi will be able to support: more clients without channels overlapping; higher speeds when necessary; and stronger security when required. It can also be used in electromagnetic sensitive areas where the use of RF could be hazardous.
LiFi, indeed, is a promising technology that will, hopefully, continue to develop and improve wireless communication.

A Computer memory uses 1024 Bytes for a KiBiByte and Computer Disk uses 1000 Bytes for a Kilobyte: Now you can stop the confusion of binary and decimal definitions of memories


    Obviously computer engineering and computer science has nothing in common regarding most of the confusions both of them present to each other and to the general public.
How?
     One of such confusions is the unit of measurement for the basic data unit which grew out from bit to bytes to  word and to other higher data units which I do  not really have time to explain here on this post.
It really seems someone is being too technical or someone is trying to deceive people with a unit definition that could literally mean something totally different, and that person could be microsoft which uses the same definition for both memory and disk which is totally wrong.  For all their highly qualified programmers, Microsoft in the early days of computers didn't use the correct units for file sizes and no one cared to stop them till it spread like wanna cry baby, later manufacturers took advantage of that in their intentional misrepresentation the capacity of their disk flash memory devices by using decimal definitions, in which a megabyte is 1,000,000 bytes.
The meomry of computer system which mostly is the RAM is defined in binary terms, with the 2n      rule,
where 8 bits, used as a memory address, can address 256 bytes of memory, 16 bits can address 64 kilobytes of memory which was where early PCs started, 32 bits can address 4 gigabytes and 64 bits can address 16 exabytes.
In the early days of the computer industry, they used "kilo" for 1,024 bytes, then the hard drive industry realised they could put bigger numbers on their drives if they used 1,000, so someone came up with "kibibyte" for 1,024 bytes. It goes kibibyte, mebibyte, gibibyte, tebibyte, pebibyte, exbibyte, zebibyte, and yobibyte, each a factor of 1,024 instead of 1,000. While the hard drive people switched to multiples of 1,000, I don't know if the memory people ever did. But you can see why it was convenient to "round" 1,000 to 1,024 for computers, but then how having more than one definition for metric prefixes was confusing.
There should just be one set of prefixes for everything.
Too bad nobody in the early days of computing thought of making a set a prefixes that are based on some multiple of a power of 2 (1,024 is 2^10 and 10 isn't a power of 2) -- that would be ideal for computers. But it seems to be too late now as Microsoft had ruined everything by following the wrong trend.
Below is the system property of my Fedora Linux and how the memory and disk are defined with differently, binary and decimal respectively.
                                                                                 Linux use Gigabytes correctly
Yottabyte which is currently the largest metric prefix for standard units remains the largest we can think of now for the big data industry, thus these prefixes go kilo, mega, giga, tera, peta, exa, zetta, yotta.
After 64 bits which can address up to can address 16 exabytes 128 bits can address 281,474,976,710,656 yottabytes and we are far from a 128 data bus as of now.
The latest we have heard about is the rumours is the 92-bit bus which will be able to give us an available data of up to 4,096 "yotta"bytes.
gib-vs-gb-table
Thank you for your time and help stop the confusion microsoft brought to the computer word.
