  How does iPhone 5 compete with the latest Android and Windows Phone?


Apple's latest release of the iPhone 5 finally resolves some key issues: the larger screen, high-speed 4G LTE network, as well as a higher pixel front camera, which previously were the advantages of the Android phone.

  Application vs Database Programming


A few years ago, I had a problem.  A database routine for processing bulk payments for LedgerSMB that was humming along in my test cases was failing when tested under load with real data prior to implementation.  Some testing showed that while it ran fine with small numbers of inputs, it eventually slowed way down as the number of inputs rose.  Andrew Sullivan, who was also on the project through a different company, suggested it was something called a "cache miss" because I...

As for which platform has more development cost, there are many different views. Using Android we no need to spend money on an expensive Mac computer, iOS test machine and $99 year fee for each developer account. While developing iOS apps does not require much testing, screen adaption, debug and script compatibility considerations. Let's see a few views shared by some developers.

  HTML5 Video and DRM


Many people call HTML5 an Adobe Flash replacement and I agree. Adobe already discontinued Flash on mobile devices. So HTML5 Video is a must for video on mobile phones and tablets. On the desktop Flash Video players are used more than HTML5 Video players but HTML5 video will work with a current web browser on a site that supports HTML5 video. Commercial video sites like YouTube will play partnered content in Flash even if you turned on HTML5 video at http://www.youtub...

  What Separates Good Designers from Great Ones


Most of the design books you read, including my own, are about how to be a good, competent designer. They are about how to make strong, reasoned design decisions and about design methods and tools. But what they won’t—can’t—teach you is how to become a great designer. The only way to be a great designer is to produce great products. Everything else is…well, everything else. I’m convinced that the people who are great designers, while assuredly they’re both talented a...

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 time I think that I’ve wr...

  Should we use Abstract class or Interface?


When we write programs, we may often get into a situation where we don't know whether we should use Abstract class or Interface when we want to define an abstract object. These two are very similar and they are interchangeable in many cases. On Stackoverflow, this question is asked lots of times and it's related to many programming languages. Also in the official documentation of PHP regarding the Abstract class and Interface, people are arguing about this. To understand this question, their dif...
