  Sequencing the Startup DNA on LinkedIn

What makes entrepreneurs different, and where do they come from? Are they born or taught? Are they unusually mobile in their careers? Does geography play a role? Do mentors and relationships matter?Numerous studies explore these questions by surveying hundreds of entrepreneurs. At LinkedIn, we take a different approach, on a different scale. By sifting through more than 120 million public profiles, we can analyze tens of thousands of startup founders’ [1]profiles – and find co...

  Permutation algorithm with JavaScript

In secondary school, we have learned permutation. Basically, for n numbers, the number of permutations for these n numbers can be calculated to n! which is called 'n factorial'. But to display all the permutations on the screen, we need to use a recursive function. The problem is how to write this function.  Next I write a program to display the permutations for n numbers with JavaScript. First, we need to understand that from these n numbers, we can first take any one number from it, and t...

  The Trouble With Bright Kids

It's not easy to live up to your fullest potential.

Here’s an introductory quote from The Story of W&L, a tale of China’s great internet divide: China does not have one so-called “national internet,” instead there’s a great divide. It encompasses the elite with ThinkPad laptops and also the grassroots with MTK Shanzhai mobile phones. Our elites are on par with America, while our grassroots are on par with Vietnam. This is the story of W&L, two representatives of China’s great internet divide. T...

  The significance of coding competition to actual work

Some friends asked this question: In secondary schools we participate in the NOI, in university we participate in ACM/ICPC, TopCoder.What's the significance of coding competition to actual work? I participated in the NOI from 1994 to 1996, ACM/ICPC from 1999 to 2000 and TopCoder in 2002 for six months. Later I paid little attention to coding competition, so I may not understand the changes in recent years and race mode . The capabilities we can get by participating the competition can be summari...

  In College, Working Hard to Learn High School Material

In June, Desiree Smith was graduated from Murry Bergtraum High. Her grades were in the 90s, she said, and she had passed the four state Regents exams. Since enrolling last month at LaGuardia Community College in Queens, Ms. Smith, 19, has come to realize that graduating from a New York City public high school is not the same as learning. She failed all three placement tests for LaGuardia and is now taking remediation in reading, writing and math. So are Nikita Thomas, ofBedford Stuyves...

  RAM is the new disk...

Jim Gray, a man who has contributed greatly to technology over the past 40 years, is credited with saying that memory is the new disk and disk is the new tape. With the proliferation of "real-time" web applications and systems that require massive scalability, how are hardware and software relating to this meme? Tim Bray, in his discussions about grid computing before it became such a hot topic, pointed out how advances in hardware around RAM and networking were allowing for the creation...

I’m talking about quite an easy-to-read (compared to TAoP) book, which, in fact, does not require any engineering or mathematical background from the reader.I am talking about C. Petzold’s “CODE”. It is a truly remarkable book about how computers work. Let me explain why I think this book is so awesome.The book starts from the very beginning, from explaining what code is, bringi...
