  The trap of the performance sweet spot

This post is about JavaScript performance but I would like to start it by telling a story that might seem unrelated to JS. Please bear with me if you don’t like C.A story of a C programmer writing JavaScriptMr. C. is a C programmer as you can probably guess from his name. Today he was asked by his boss to write a very simple function: given an array of numbered 2d points calculate vector sum of all even numbered points... He opens his favorite text editor and quickly types somet...

  The seven rules of Unobtrusive JavaScript

I've found the following rules over the years developing, teaching and implementing JavaScript in an unobtrusive manner. They have specifically been the outline of a workshop on unobtrusive JavaScript for the Paris Web conference 2007 in Paris, France. I hope that they help you understand a bit why it is a good idea to plan and execute your JavaScript in this way. It has helped me deliver products faster, with much higher quality and a lot easier maintenance. 1. Do no...

  Android hardware fails more than iPhone, BlackBerry; repairs cost carriers $2 billion

Repairs to Android smartphones cost wireless carriers $2 billion per year according to a new year-long WDS study that tracked 600,000 support calls around the globe. Android’s popularity and the introduction of a number of low-cost smartphones has put a strain on the wireless business model, WDS noted in its report. “Deployment by more than 25 OEMs and lower-cost product coming to market is leading to higher than average rates of hardware failures and, in turn, return and repair cos...

  How I Learned to Program

Programming is, without a doubt, the most mentally rewarding thing I've ever done. Programming taught me that life should be fun, filled with creativity, and lived to the fullest. Programming taught me that anything is possible; I can do anything I want using only my mind. Programming also taught me that learning is fun. It showed me that the more you know, the more power you have. Programming showed me that a life filled with learning is a life worth living. Programming revealed to me wh...

  Comparing Floating Point Numbers, 2012 Edition

We’ve finally reached the point in this series that I’ve been waiting for. In this post I am going to share the most crucial piece of floating-point math knowledge that I have. Here it is:[Floating-point] math is hard.You just won’t believe how vastly, hugely, mind-bogglingly hard it is. I mean, you may think it’s difficult to calculate when trains from Chicago and Los Angeles will collide, but that’s just peanuts to floating-point math.Seriously. Each ti...

  SkipList in Go

Algorithmic thinking is the must-have in the coding world, so I have been keeping the routine of algorithm practice every week, consolidating my knowledge of data structures on one hand, and improving my coding skills as well. A difficult one happened to be stuck in my mind- Implement SkipList with Go, which took me quite a weekend. Below is the front-line report of how I finally got the hang of it. First, from its concept. Wiki has explained it well. a skip list is a probab...

While talking about bit operation, programmers usually think about its efficiency. In embedded programming and system core optimization, appropriate use of bit operations is always a fascinating. When finding a job, it will help you a lot if you use bit operations when writing codes. Mastering simple bit arithmetic skills is necessary. 1. Get maximum int value int getMaxInt(){           return (1 << 31) - 1;//...

  Thoughts on Python 3

I spent the last couple of days thinking about Python 3's current state a lot. While it might not appear to be the case, I do love Python as a language and especially the direction it's heading in. Python has been not only part of my life for the last couple of five years, it has been the largest part by far. Let there be a warning upfront: this is a very personal post. I counted a hundred instances of a certain capital letter in this text. That's because I am very grateful for all the opport...
