Hacking Vs. Programming
What is the difference between Hacking and programming? One opinion I have heard expressed is that a hacker can put a lot of code together in a hurry but if a change is needed the code has to be completely rewritten. A programmer may take a little longer but if changes are needed they are more quickly and easily installed without the need for a complete rewrite. One source I heard attributed an observation like this to Maggie Johnson of Google. It rings true to me though. Hacking is usual...

How I Develop Things and Why
I've always considered myself a bit of a software junkie. Nothing excites me more than a great piece of new software. Some of my best childhood memories are our trips to Grandma's house, where I'd have access to a computer with a dial-up connection that I'd use to obtain freeware and shareware. I'd bring 4 or 5 floppies with me and try to cram all the games, waveform editors, and utilities that I could sneaker-net home. Luckily today, excellent software written with passion oozes out of ...

In praise of impractical programming
Although it’s become a cultural mainstay now, I still remember when I first saw that thick book — the one with the wizard on the cover — about a school for magic where wonders are easily conjured by those who know the proper spells. Of course, I’m talking about the Structure and Interpretation of Computer Programs. There was that other book with the spells, but the “Wizard Book†sincerely claimed to teach magic. For the past few years, I’ve been ...

Generate first N prime numbers
Recently I am taking an online course named "Startup Engineering" on coursera. There is one assignment which is to use NodeJS to write a program to generate the first 100 prime numbers. This may be very easy for many people. Here I just want to share with you the code to generate not only the first 100 prime numbers. but also any number of prime numbers. Below is the code snippet: //Helper class to generate prime numbers var PrimeProcessor=(function(){ var primeArray=[]; functio...

What kind of automated testing does Facebook do?
We do several kinds of testing. Some specifics:For our PHP code, we have a suite of a few thousand test classes using the PHPUnit framework. They range in complexity from simple true unit tests to large-scale integration tests that hit our production backend services. The PHPUnit tests are run both by developers as part of their workflow and continuously by an automated test runner on dedicated hardware. Our developer tools automatically use code coverage data to run tests that cover the ...

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...

Fear of Ignorance
This past week, I was interviewing a candidate for a VP role along with two of our engineering leads. Everyone in the room excluding myself was classically “technical†– they could write code, had experience solving hard software problems and a background in computer science. I wrote my last line of PHP in 2004, and it had to be rewritten by a real programmer within 6 months.During the interview, we had the following exchange (due to an imperfect memory, I’ll ...

Tips for a better first-time hackathon experience
Here are a few things you can consider. These are by no means the only way to go about hackathons, just what's worked for me.ProjectI strongly strongly recommend doing something you haven't done before. Even if you're going into a hackathon with the intention of winning, trying something new is always fun and will keep you engaged throughout the event. Jump into mobile development, try hardware hacking, write a compiler, whatever; it's always fun to try out new things.Sticking to things you're c...
