  "Simplicity" is not a simple concept

I've come to avoid using the word "Simplicity" or its variants ("Simple," &c.) It means too many different things to different people.For example, my original land-line phone was simple:It's simple by eliminating extraneous use cases. It only handles one user scenario, the one that was the most common when it was invented. If we think of the number of affordances and the number of uses, this kind of simplicity lowers the number of affordances by lowering the number of uses. I call this kind ...

  Top 20 programming languages in April 2011

Next picture shows the Top 20 programming languages in April 2011 from TIOBE. From the picture, we can find the most popular programming languages are the different representatives of programming language styles. And some of them are popular because the platforms which use this programming language is very popular.For example C#, because of Microsoft, this language is used in .Net platform. Many users are using this programming language.Also, Java, C and C+ are the top 3 languages in he world. T...

  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...

  Coming full circle

Experts often end up where they started as beginners.If you’ve never seen the word valet, you might pronounce it like VAL-it. If you realize the word has a French origin, you would pronounce it val-A. But the preferred pronunciation is actually VAL-it.Beginning musicians play by ear, to the extent that they can play at all. Then they learn to read music. Eventually, maybe years later, they realize that music really is about what you hear and not what you see.Beginning computer science stu...

  Call of Duty Elite Has Amazing Security

I had tried to register for Elite yesterday, and the servers were being funny, so I wasn't sure if I'd registered. I just now tried to reset my password, and I got the following:Hello JoshForgot your password? These things happen. Access your account with the password below:{Actual Unencrypted Password}Really? They're storing hundreds of thousands of passwords in plain text??EDIT: Not sure what the downvotes are for, surely it's not because huge companies like Steam and Sony never get hacked, an...

  The roots of Lisp

(I wrote this article to help myself understand exactly what McCarthy discovered. You don't need to know this stuff to program in Lisp, but it should be helpful to anyone who wants to understand the essence of Lisp-- both in the sense of its origins and its semantic core. The fact that it has such a core is one of Lisp's distinguishing features, and the reason why, unlike other languages, Lisp has dialects.)In 1960, John McCarthy published a remarkable paper in which he did for programming somet...

  Android Hardware Buttons are not broken, let me tell you why

This post is written as a reaction on Christoffer Du Rietz’s article The Android Hardware-Buttons Are Broken. In his article Christoffer explains how the Android back button shows inconsistent behavior like doing different actions when it is used on the same screen.In the following article I will try to explain that this behavior is not broken. Instead it is exactly what the Android developers had in mind while designing the back button behavior.The way the back button is broken according...

  Basic Patterns for Everyday Programming

For most of you the patterns mentioned below should be nothing new. These are very basic stuff we slap into our code everyday and at times feels they are actually code smells than smart patterns. However, I've been doing some code reviewing lately and came across many code that lacks even these basic traits. So I thought of writing them down as a help for novice developers who would want to get a better grasp at these.These patterns are commonly applicable in most general purpose programming lan...

  CSS box-shadow Can Slow Down Scrolling

Working on one of the Chromebooks Google lets you borrow on Virgin America flights, I noticed scrolling down the page on my airbnb.com dashboard was much slower than on my normal laptop. I chalked it up to weak Chromebook hardware, but other sites were scrolling just fine. box-shadow had caused slow scrolling on our search results page before, so I did some investigation.I used Chrome's Timeline tab to see the duration of paint events on the page. Before each test I forced a garbage collection a...
