10 Tips To Make Your C Program Effective
The beauty of any code lies not only in finding the solution to a given problem but is in its simplicity, effectiveness, compactness and efficiency( memory ). Designing the code is harder than actually implementing it. Hence every programmer should keep a couple of basic things in mind while programming in C. Here we introduce you to such 10 ways of standardizing your C code. 1. Avoid unwarranted function calls Consider the following two functions: view source print? 1 void str_print( c...

Everything You Thought You Knew About Learning Is Wrong
Taking notes during class? Topic-focused study? A consistent learning environment? All are exactly opposite the best strategies for learning. Really, I recently had the good fortune to interview Robert Bjork, director of the UCLA Learning and Forgetting Lab, distinguished professor of psychology, and massively renowned expert on packing things in your brain in a way that keeps them from leaking out. And it turns out that everything I thought I knew about learning is wrong. Here’s wh...
You know what UTF-8 is when you see it?
When we are coding we may often see some encoding specifications in our source codes such as UTF-8,GB2312. Do you know what these encoding mean and why we need them? In this post, Julián Solórzano will introduce the most widely used encoding specification around the world accomodating all different character sets in the world. UTF-8 is a method for encoding Unicode characters using 8-bit sequences. Unicode is a standard for representing a great variety of characters from many ...
The faster-than-fast Fourier transform
The Fourier transform is one of the most fundamental concepts in the information sciences. It’s a method for representing an irregular signal — such as the voltage fluctuations in the wire that connects an MP3 player to a loudspeaker — as a combination of pure frequencies. It’s universal in signal processing, but it can also be used to compress image and audio files, solve differential equations and price stock options, among other things.The reason the Fourier...

Roundup on Parallel Connections
A lot of blogging and follow-up discussion ensued with the announcement that IE8 supports six connections per host. The blogs I saw: IE8: The Performance Implications IE8 speeds things up IE8: 6 Connections Per Host IE 8 and Performance Testing IE8.s Connection Parallelism IE 8 Connection Parallelism Issues It’s likely that Firefox 3 will support 6 connections per server in an upcoming beta release, which means more discussion is expected. I wanted to pull all the facts into one place an...
