  Why I Quit My Job to Start a Tech Company

Back in November of 2006, before NY Mag and TimeOut put startups on the cover, before the “tech bubble”, before Twitter and Foursquare were popular, before working at a startup in NY was considered a reasonable thing to do, I was a private equity investor for a $1.6 billion fund called Quadrangle Group. It was just my third year out of college and I made a little over $250,000. For a Brazilian immigrant who spent most of his childhood kind of worried he would have to do physica...

  Some Thoughts on Twitter's Availability Problems

As a regular user of Twitter I've felt the waves of frustration wash over me these past couple of weeks as the service has been hit by one outage after another. This led me to start pondering the problem space [especially as it relates to what I'm currently working on at work] and deduce that the service must have some serious architectural flaws which have nothing to do with the reason usually thrown about by non-technical pundits (i.e. Ruby on Rails is to blame). Some of my suspicions ...

  JavaScript interview questions

This post will cover the JavaScript questions I have encountered and have seen during my programming career. They will mainly focus on vanilla JavaScript though there are lots of excellent frameworks out there and many people are using them in their daily work. this keyword this keyword is an very important but easy to confuse concept in JavaScript since it is always referring to the calling object of the function. 1. What will be the output of below code snippet? function User(name) { this....

  Notes on Programming in C

Introduction       Kernighan and Plauger's The Elements of Programming Style was an important and rightly influential book.  But sometimes I feel its concise rules were taken as a cookbook approach to good style instead of the succinct expression of a philosophy they were meant to be.  If the book claims that variable names should be chosen meaningfully, doesn't it then follow that variables whose names are small essays on their use are even better?  Isn't MaximumV...

  Why we don’t hire .NET programmers

Skip my post and read this one instead.  It says the same thing, but less offensively.  (Or, rather, more offensively to Facebook and Google employees, less offensive to .NET developers, though the underlying message is the same.) Tuesday midnight edit: After >500 comments, >1000 tweets, and >1000 Facebook likes, I’m closing comments on this thread so we can all get back to work.  The very last comment takes the cake, however, and is a fitting close.  Th...

  Android Tutorial: Creating and Using an SD Card in the Emulator

In a previous post, I mentioned how user-friendly Android is for developers. There’s extensive documentation and information on the architecture, the different components and best practices. However, the documentation has a few blind spots. Many of the tools have little documentation and no usage examples. The information is there, it’s just hidden behind a few layers of Android theory.So I’m going to try and document a few of the basic things that you’ll probabl...

  A Different Kind of Technical Interview

Everyone who's been programming professionally for a while knows the standard format of the technical interview. You go in, there's a whiteboard in the room, and you write code on it to answer questions.Everyone also has the same basic complaints about these interviews. In a normal work environment, you have access to an API or search engine, but at a whiteboard you don't. Whiteboard questions generally don't include much in the way of overall design, and they're typically limited to simple algo...

  Short SASS tutorial

If you learned CSS before, you should know that CSS is not a programming language. You can use it to design webpage style, but you cannot use it for programming, i.e, CSS is what designer uses, not what programmer uses. Programmer may think that CSS is very troublesome, it has no variables, no conditional statements, it just allows line-by-line description of HTML elementsLuckily, CSS preprocessor appear which makes CSS programmable. The general idea of CSS preprocessor is using a programming la...

  Device Experiences & Responsive Design

Most recently LukeW was the Chief Product Officer (CPO) and co-founder of Bagcheck which was acquired by Twitter Inc. in 2011. Luke is also the author of the book Mobile First and was Chief Design Architect (VP) at Yahoo! Inc. While the task of designing Web applications and sites for multiple devices can be daunting, two techniques can make the process more manageable: classifying device experiences and designing/building responsively. Here’s how these two approaches can work toge...

  The mystery of Duqu Framework solved

The Quest for Identification In my previous blogpost about the Duqu Framework, I described one of the biggest remaining mysteries about Duqu – the oddities of the C&C communications module which appears to have been written in a different language than the rest of the Duqu code. As technical experts, we found this question very interesting and puzzling and we wanted to share it with the community. The feedback we received exceeded our wildest expectations. We got more than 200...
