How a Data Scientist Tweaked OKCupid And Becamse Top Match For 30,000 Women

PinBytes: Here is a story of a data scientist who was able to separate the women on OKCupid into seven groups and hence, he was able to figure out the important questions for which women look out for honest answers. He gave all the answers honestly and he became a top match for 30,000 women on OKCupid.

OkCupid is known by many names like ‘The Google of online dating’, ‘The best free dating site’ and many more names.

OkCupid works very straightforward. This free dating site finds out two people’s compatibility by their answers on the specific questions. The more similarly they answer the questions, the higher the chances are that they will be a good match.

The data scientist Chris McKinlay as a grad student spent some of his free time on OKCupid. After having access to a supercomputer, he began to analyze OKCupid’s question data sets and the answers, he was able to find a solution set to the same.

He was able to separate the woman around him into seven groups. By segregating, he was able to figure out which group had the highest chance of compatibility with him and which questions were most important to the women from that group.

This way, he was able to know the key questions. So he answered all those questions honestly and became the top match for 30,000 women and began receiving a huge increase in unsolicited messages. Finally, he found his true love on his 88th date.

Here is a video of Chris McKinlay explaining how he hacked OkCupied:

Who Were The First 10 Users On Facebook?

PinBytes:Who were the first ten users on Facebook? These are Harvard graduates who showed their interest to try the blue network during its initial days. Read further to know about them.

Facebook, the blue colored network, has around 1.6 billion monthly active users. That’s a deserving figure for a social platform that has been endeavoring to remain on the throne for the last 12 years. Facebook’s initial days were featured in the movie The Social Network which was an adaptation of the book “The Accidental Billionaires”. However, the actual story was a bit different.

An interesting question about the social networking giant is — who were the first ten users on Facebook? It’s easy to decipher, the creator Mark was the first one to create an account on facebook but the curiosity escalates ten-fold as one moves down the list to see who’s the second, third, and so on. The original ID number given to these profiles are also mentioned. They are not in sequence as some IDs don’t exist or were later assigned to other users, mainly Facebook employees.

Here are the first 10 users on facebook:

Mark Zuckerberg (ID – 4)

zucker102-1266659-920x526

The CEO was obviously the first person to have an account on Facebook. Technically, he was fourth as he may have wasted the first three profile IDs. Mark has become a father to Max after he tied knots with her long-time love interest Priscilla Chan. Stories like having an ‘I’m CEO Bitch!’ business card and insulting his girlfriend on a public platform reflect the rebellious attitude he nurtured as a college guy. Over the years, Zuckerberg has turned into a mature person. The older version of Mark wants to connect technology deprived people to the digital world with projects like Internet.org and internet-beaming drones.

Chris Hughes (ID – 5):firstmover-chris-hughes-hed-2012

One of the names in the Facebook co-founders list was the second person to have a Facebook profile. The Harvard graduate served as Facebook’s spokesperson until the year 2007 when he left to volunteer for Obama’s Presidential election campaign. Hughes founded Jumo before joining as the Executive Chairman and Editor-in-Chief for The New Republic magazine. Hughes bought the majority of the stake in the magazine which he sold to Win McCormack in Feb 2016. The pillars of the century-old magazine weren’t capable enough to bear the weight of the digital skyscraper Hughes wanted to build.

Dustin Moskovitz (ID – 6):Dustin-Moskovitz-_2664067b

Another Facebook co-founder, the Florida-born American, was Zuckerberg’s roommate during their Havard years. After spending ‘few days’ learning PHP, Moskovitz was all set to kill the bugs. He was the CTO during the initial years and then the VP of engineering. Dustin, along with Justin Rosenstein, left Facebook in 2008 and created Asana, a work tracking platform based on the software-as-a-service model. Apart from being an angel investor to many startups, Moskovitz and his wife Cari is the youngest couple to sign The Giving Pledge.

Arie Hasit (ID – 7):enhanced-buzz-26182-1359929052-16

He was one of the earliest to have a Facebook profile even though he wasn’t associated with the creation of the social network. At Harvard, he was an arts bachelor studying Israel History and wrote for the Harvard Political Review. He currently resides in Jerusalem where he serves as a student rabbi (a teacher) for a non-profit called NOAM Olami. It involves young people aged from 8 to 18 years who are taught Jewish values, Masorti Judaism, leadership skills etc.

Andrew McCollum (ID – 26):Capture-768x430

Another person from the founding team, McCollum has been away from the limelight all these years. He dropped out and worked at Facebook when it was a startup. He went back to Harvard in 2007 and completed his bachelor’s in computer science. McCollum co-founded Jobspice and traveled around the world to pursue his hobby of being an angel investor along with continuing his Masters of Education at Harvard. He was an entrepreneur in residence at Flybridge Capital Partners and currently works as the CEO at Philo which provides internet TV in U.S. universities.

Colin Kelly (ID – 27):kelly

Being a physics research assistant at Harvard, he studied techniques for analyzing molecular structure. He obtained a JD degree from Columbia University School of Law and gained popularity in the Windsor v. the United States civil rights case in which the State was challenged for discriminatory treatment against homosexual couples when claiming the federal estate tax exemption. Kelly currently lives in New York and works as a Tax Associate at Paul, Weiss, Rifkind, Wharton & Garrison LLP.

Mark Kaganovich (ID – 28):Mark-Kaganovich

Kaganovich was a biochemistry graduate at Harvard where he met Zuckerberg during math classes and dorm hangouts. “I remember him urging me to put up a profile picture, because I was slow to do so,” he told Rob Fishman of BuzzFeed. Mark (Kaganovich) was a research assistant at Weizmann Institute and built a scientist social network called Labmeeting after he graduated from Harvard. In 2009, he went Stanford for a Ph.D. in Genetics. Since the year 2013, Kaganovich has been working as the CEO (and co-founder) of SolveBio based in New York, a company involved in health research and assists pharma companies with its analyzed data.

Get Nostalgic: Play These Windows 3.x Games In Your Web Browser

PinBytes: Check out the games and software from the time of Microsoft Windows 3.x and 3.1x in the collection published by Internet Archive. These will work right in your web browser without the need of any plugin.

Remembering the early computers from the 90s does induce a nostalgic feeling, mostly for our parents or elder siblings. People who were a child or not even born during that time may find it ‘normal’ to talk about those machines with minimalistic graphics. There was no internet back then, at least for the common people. An average PC user had a whole pack to CDs or I should say floppy disks to store their software collection. Over the years, these have drowned into the quickly depositing sand of technological advancement and replaced by cloud storage.

We have come a long way. It’s good to have high-speed internet access and we don’t have to deal with a bunch of CDs to install software or watch movies. Everything has become simpler from the technology point of view but more complicated than ever if we talk about the emotional point. The rise of the internet and the technology has detached us from our social life. One praiseworthy thing the internet has done is preserving the past. Whether it’s about the Apple Lisa buried in a landfill or the first Moon Mission by NASA, all of it is just a few clicks away.

Internet Archive, a San Francisco-based nonprofit digital library made attempts to rejuvenate older Windows games. A couple of months ago, they published an archive containing all the famous games and software from the time of Windows 3.x and Windows 3.1x. The ‘Windows 3.x Showcase’ contains 49 entries. It is a part of a giant Software Library hosted by Internet Archive having thousands of such playable files which were originally created for MS-DOS, Apple Computer, etc.chomp

I wasn’t even born at the time when people used to enjoy these games so I didn’t want to miss the shot this time. The very first gamed I played was Ms. Chomp in which I was assigned the role of a Pac-Man-like smiley who had to eat all the dots in the maze and save himself from the ghosts at the same time. I am glad that I ate around ninety-five percent of the dots before getting caught by one of the ghosts. Actually, I ran into him myself, by mistake, though. I had a great time enjoying other games like Brickbuster and TDK Pinball machine.

The best part of the Windows 3.x Showcase is that you don’t have to install any software or plugin to run the games and software. They just work in your web browser using the DOSBox emulator. A detailed description about each one of them is also provided.

Mark Zuckerberg Teaches How Repeat Loop Work In Programming

PinBytes:Today I’m sharing an old video from 2013 that features Mark Zuckerberg teaching the basics of repeat loop. This video was a part of Code.org’s Learn To Code movement and is worth a watch.

With its Learn To Code movement, Code.org is working to ensure that everyone learns basic programming logic and it aims to do so from the very start.

To kickstart its program few years ago, Code.org took help from the likes of Bill Gates and Mark Zuckerberg. While Bill Gates shared some wisdom regarding ‘if’ statements, Mark Zuckerberg explained the ‘repeat’ loops.

It’s amusing to see Facebook CEO explaining the repeat loop. “One thing that computers are really good at is repeating commands,” says the tech giant, in his small guest lecture on repeat loop.

He explains how sending an email to everyone on Facebook would take him a century but loops make this job easier.

Later in the video, he takes the example of Angry Birds. Well, I won’t spoil everything and let you listen to Zuckerberg’s explanation:

18-year-old Teenager Dies While Unplugging His Phone At Internet Cafe

PinBytes: Xiong Xuan, a resident of Wuhan, China, died last week while unplugging his phone from the charging at an internet cafe. The doctors pronounced the cause of death to be the electrical injury. The license of the internet cafe is cancelled and the investigation is going on.

In an unfortunate incident, an 18-year-old teenager from China met with an untimely death while unplugging his charging mobile phone from a computer at an internet cafe.

This incident took place in Wuhan, China. Xiong Xuan was a regular internet user at the local cafe and he worked as a factory worker at a garment factory, according to his brother Xiong Feng.

This incident took place last week on April 15 when Xiong visited the internet cafe after finishing his shift at work. His elder brother Feng was also present at the scene.

Feng said: “He let out a shout when he pulled on the cable and then his foot made contact with the steel legs of the table.”

Feng told the local reporters that his brother was seated at his usual seat and after being done with his computer work, he reached to unplug the charging cable when this incident took place.

The elder brother also recalls that his brother started foaming at the mouth and fainted. Sadly, nobody at the internet cafe came to help him. “He was obviously hurt, but none of the staff helped,” he told local reporters.

Later Feng called his uncle and took his unconscious brother to nearby Panlongcheng People’s Hospital.

Xiong Xuan was pronounced dead after 20 minutes by the doctors who called it an electrical injury.

For now, the license of the internet cafe has been suspended and investigations are underway.

How A Super-powerful Waterjet Cuts A Laptop In Two Parts

PinBytes: What will happen if you try to cut a laptop in two parts using a waterjet? Before you make any assumptions and answer this question, let me tell you that here I’m talking about a high-powered waterjet spitting fury at 60,000 psi. I’ll avoid spoiling the outcome and suggest you to go ahead and watch the video yourself.

waterjet cutter is an industrial tool that’s capable of cutting a wide variety of materials using an extremely high pressure of water, or a mixture of an abrasive substance and water.

Now combine the same with a smartphone or camera and you’ve got a sensational video of an intense waterjet cutting gadgets in a spectacular fashion.

With YouTube and the newly released Facebook Live video, the film-making has become super-democratic and people love watching things getting destroyed in a unique fashion.

One of the latest additions to this list of YouTubers is the channel Cut In Half. Within just 3 weeks, the channel has garnered hundreds of thousands of viewers.

The channel uses an Omax Abrasive Waterjet that cuts anything with a power of 60,000 psi jet of water. If you want to get an idea of this extreme pressure, just for comparison, imagine a car tire that has air filled at 35 psi.

In its recent video, the channel cuts a 2007-era Toshiba laptop with a water jet.

Dear laptop, rest in peace — you won’t be waking up again!

Arduino Comes To Raspberry Pi And Other Linux ARM Devices

PinBytes: The Arduino project has finally released Arduino IDE for Raspberry and other single-board ARM computers. Combining Raspberry Pi with Arduino is a recipe for great electronics projects and fun-filled DIYing.

If you’re into electronics DIY stuff, you’ve probably worked with Raspberry Pi and Arduino. While they could be used to solve similar problems at many occasions, they are quite different. For beginners, Arduino is a microcontroller — a single component of a computer — and Raspberry is a fully functional computer.

Till now, Arduino IDE and Raspberry Pi existed miles apart from each other. However, finally, the experimental builds of Arduino IDE for Raspberry and other ARM devices are now available.

This open source Arduino software makes it easier to write code and upload it to your board. Written in Java, this software could be used with any Arduino board in the market.

This has been made possible due to the continuous efforts and hard work of open source developers working on the Arduino project.

arduino-ide-on-raspberry-pi

Now, you can just download the package from arduino.cc website and type “install” to get started.

If you are wondering how the Raspberry Pi version is different from the one we spot on Windows and OS X, let me tell you that everything is just the same.

Which Is The Most Popular Web Browser Being Used In 2016?

PinBytes:Which web browser do you prefer for browsing the web? Your answers might differ but Google Chrome continues to rule the web with the most number of users. The latest data from US federal government’s Digital Analytics Program reiterates the same fact.

There are many websites that track the number of people using a particular web browser, operating system, and other services. However, not many of them provide a reliable data.

On the other hand, US government Digital Analytics Program (DAP) tracks the number of people on government websites in real time and gives us a standard running count of the last 90 days.

If we take a look at the most popular web browsers being used by people, Google’s Chrome browser wins the fight by a large margin. This was a choice of more than 2 billion visitors.

The second most popular web browser has surprised many as Apple’s Safari stole the second prize with 21.9 percent visits.

As expected, the third place was secured by Microsoft’s infamous Internet Explorer whose IE 6 to IE 11 versions gathered 20.1 percent visitors.

IE was followed by Mozilla’s Firefox web browser, which continues to stumble with just 8.2 percent visitors.

Talking about the new and shiny Microsoft Edge, it’s still not getting many users and it’s stuck with just 2.5 percent users. Android’s native mobile web browser comes last with 1.6 percent visitors.

Coming back to Safari, 19.1 percent visitors were using iPhones — I hope it automatically explains the large numbers for Safari.

The federal government explains that this data comes from a unified Google Analytics account for all US government websites. The government doesn’t forget to remind the people that its DAP program doesn’t track visitors and anonymises their IP addresses.

Edward Snowden Shows How To Tweet Like A Boss After Panama Papers Leak

PinBytes:In a short span of time, Edward Snowden has built an impeccable reputation on Twitter. In the wake of the latest Panama Papers leak, once again he showed why he is the only “boss” NSA would fear.

Edward Snowden, who once worked for the CIA (Central Intelligence Agency), is known for leaking the classified information from the NSA. Since then, he’s acting as an activist who points fingers at the operations of different governments from time to time.

After the recent Panama Papers leak — one of the biggest data leaks in the history, Edward Snowden is once again busy targeting those whose name appeared in the much talked about leaks.

Edward Snowden came to Twitter last year. Since then, he has been following just one Twitter account. In the wake of the recent leaks , he is putting pressure on David Camron, the British Prime Minister. Mr. Camron has been facing some tough times recently as he admitted on Thursday to profiting from the sale of shares in some offshore funds.

Mr. Snowden has stated that the next 24 hours could change the Britain.

Snowden also said that it was up to the British public if their Prime Minister resigned. He took the case of Iceland, where the Prime Minister resigned after ten percent of all voters were on the streets within 24 hours of the less.

His Twitter account has been a combination of sarcasm and ‘in your face’ humor. He tweets with solid facts and points direct fingers.

Windows 9 Mystery Reappears In A Recent Microsoft Document

PinBytesWindows 9, the never-released operating system, has been spotted once again in a latest Microsoft patent. This new document might finally solve the “what happened to Windows 9” mystery. The new theory suggests that Windows 9 was supposed to be the OS that was launched last year, while the upcoming Redstone update was originally projected as Windows 10.

Back in October 2014, Microsoft shocked the world by announcing its new operating system Windows 10. Since then, people have been making guesses about Windows 9 that disappeared like a ghost.

This never-launched operating system from Microsoft, that was supposed to hit the market before Windows 10, has reappeared in a Microsoft patent filing. This document was published on March 31, 2016.

Before we speculate the meanings of this appearance, let’s take a look at the patent document that mentions Windows 9. The document is titled “Compiler Caching for Runtime Routine Redundancy Tracking”.windows-9-mystery-patent-solved-windows-10-threshold

Windows 9 mystery finally solved?

Microsoft never revealed why it didn’t launch Windows 9 and skipped it to release Windows 10. Some might argue that the differences between Windows 8.1 and the next release were so big that it was important to make a jump.

Based upon the mention of “Windows 9 Threshold” in the patent document, one theory, that’s floating across the inernet, provides some satisfactory answer to the Windows 9 mystery.

The theory suggests that Windows 9 was supposed to be the Windows version that was launched last year, while the upcoming Redstone aka Anniversary Update was originally projected as Windows 10.

This theory makes sense because Microsoft was calling the first iteration of Windows as Threshold and the lastest one is known as Redstone.

In simpler words: Windows 9 = Threshold (July 2015), Windows 10 = Redstone (July 2016)

Whatever might be the case, Windows 9 is a thing of past and Microsoft is busy making Windows 10 better and bringing new features like Bash on Ubuntu.
