How Chamath Palihapitiya became a “Midas touch” investor…

Chamath Palihapitiya

Do you know why Silicon Valley of the United States is one of the most important areas in the world? And did you ever think is there any Sri Lankan who plays a major role in Silicon Valley?  Silicon Valley is a nickname for the southern portion of the San Francisco Bay area and it is the high-tech dominated area of the world.

Chamath Palihapitiya

Chamath Palihapitiya is listed as a one of the coolest people who matter most in Silicon Valley. He is  a highly-successful entrepreneur  who was born in Sri Lanka. Within the high-tech community, he is known as a sharp investor and executive. At his age of six, he  moved to Canada with his family. In 1999, he graduated from the University of Waterloo with a First-Class Honors degree in Electrical Engineering and moved to California in 2000. Then he joined AOL and became the youngest VP in AOL’s history at the age of 26.

He has worked in several companies and he was a member of Facebook’s senior management team as well. He served in various roles during his four-year stint at Facebook and he was was a major force in the launch and the incredible growth of Facebook, but he quit his job at Facebook in 2011. Within the high-tech community, he’s known as a sharp investor and executive who made it big when Facebook went public.

 

Chamath Palihapitiya  as a venture capitalist

After quitting Facebook, he started his own fund called Social+Capital Partnership.  In 2015, the firm changed its name to Social Capital. Chamath Palihapitiya is the founder and CEO of investment firm: Social Capital. The firm has stood out strategically, with a focus on technology in financial services and education, health care and on software as a service. Social Capital started investing in health and education when those fields were being largely neglected by other venture capitalists.

He launched a new “blank-check” company in partnership with the London-based venture capitalist  firm named Social Capital Hedosophia Holdings Corp. This company is formed for the purpose of entering into share exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. Recently they announced the pricing of its initial public offering. And they  listed  60,000,000 units at a price of $10.00 per unit on the New York Stock Exchange. After listed  their shares on the stock exchange on  last Wednesday(17/09/13)  it went up to 3.5% in the first half of next day.

 

This new “blank-check” company doesn’t have any products or customers. And also it doesn’t own anything yet. But initial shares of the company  were up that much because shareholders trust the strategies of  Chamath Palihapitiya. The company plans to buy stakes in private tech companies. They will buy  from minority stakes to controlling interests to full ownership.

He achieved all these because of his unflagging dedication and he will become one of the billionaires in the world near future.

This Company began to sell its products commercially on its own Website in August 2013. And they started to sell their products on Amazon.com in September 2013. In August 2014, SmartThings Inc announced that they had reached an agreement to be acquired by Samsung Group which is a South Korean multinational company. But SmartThings Inc would operate as an independent company within Samsung’s Open Innovation Center. The acquisition was the foundation to move into the internet of things space by Samsung. Now Samsung SmartThings is becoming one of the biggest and most recognizable names in the IoT space.

One of the biggest problem when building a smart home is that, usually the user has to deal with the disparate collection of devices. Samsung SmartThings concerns about that and designed their SmartThings technology with reducing those difficulties. They provide a single hub and app those can be used to control your home and convert it into a smart home.

In Samsung SmartThings technology, Hubs are used to connect with IoT devices through the Internet. The user can monitor, control, and automate IoT devices using integrations. Google Home, Amazon Echo, Amazon Echo Dot and Amazon Tap are the devices which belong to voice assistant category products of  Samsung SmartThings.

Using voice assistants, the user can get help from Google voice Assistant service to play music, provide information, news, sports scores, weather reports, and much more. Also, user can stream music from Google Play Music and YouTube. The user can control a wide range of connected outlets, lights, switches, and dimmers with user’s voice commands. This technology helps to use SmartThings Routines to control multiple devices with single voice command.

Samsung SmartThings technology supports devices in several brands. So you don’t need to get lights, switches, and outlets in Samsung brand.

You can control outlet with your voice commands using SmartThings and the Google Assistant or Amazon Alexa.

The Samsung SmartThings second-generation hub supports wider varieties of devices and third-party integrations, such as for Amazon Alexa. It has dramatically improved SmartThings.

The biggest Ad Fraud Ever

A group of Russian criminals called “Ad Fraud Komanda” or “AFK13” were caught earning money between $3 million to $5 million each day. They earn money by doing faking clicks on video ads on the advertising market. It is revealed by White Ops which is a security firm that provides online fraud detection solutions. This criminal is the biggest digital ad fraud ever.

 First they created 250,127 distinct URLs and more than 6000 domains that appeared to belong to real reputed publishers. They misled the algorithms that decide where the most profitable ads would direct into buying their fraudulent web space. These algorithms typically make bids for ad spaces which are most suitable for advertisement’s intended audience. Hence their fraudulent web space was purchased by many reputed brands.

 Then they invested heavily in a bot farm that consisted more than 570,000 bots. Next they triggered faked traffic on the ads using those bots, thereby driving a huge amount of revenue thanks to the pay-per-click scheme they’d exploited. Those bots have watched more than 300 million video ads a day, with an average payout of $13.04 per thousand fake views. This bot army was also programmed in order to imitate the actions of real people, such as faked clicks with mouse movements and social network login information. White Ops called this crime as Methbot campaign.

White Ops provided an example of how they faked a domain

They used thousands of IP addresses to make those bots appear more real, so they can bypass typical anti-fraud detection measures. Theses IP addresses were associated with major U.S Internet Service Providers, so it seemed they were based in America itself. Those IP addresses were fraudulently obtained from at least two of the world’s five regional Internet registries.

 

Those who were spending on the automated systems were losing a significant amount of money, not only because of the Methbot but also due to other similar campaigns. Those funds might never be retrieved. The White Ops company wrote in its white paper. “At this point the Methbot operation has become so embedded in the layers of the advertising ecosystem, the only way to shut it down is to make the details public to help affected parties take action.”

Get to know about Ultrasonic Sensor HC-SR04

Ultrasonic Sensor HC-SR04 is used to measure distance. We can find precise distance to an object from the sensor, or can used to detect when something is within range of the sensor. It can measure distance with high accuracy from 2cm to 400 cm.  Its operation is not affected by darkness or light .Because it uses sound to measure distance.

Ultrasonic range finder measure distance by emitting a pulse of ultrasonic sound that travels through the air until it hits an object. It measure the time of the sound pulse which travel forward & back to the sensor when the pulse hits the object. Then it sends an electrical signal to the Arduino with information about the time that sonic pulse traveled.

Ultrasonic range finder has 2 transducers.

  • Transmitting transducer
  • Receiving transducer
