  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...

  Which one cost more in development : Android vs iOS

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. Nan Li, ERP/SAP/Mobile network/Japan/Apple/KKK@ifanr Because of the performance of iOS, it actually has domina...

Before diving into the differences between the two concepts, it’s important to take a step back and understand what a cloud service really is. Cloud computing primarily refers to large storage of data, programs, and operations that are accessible via the Internet and are not stored on a user&rsquo...

  What to put on whiteboard during an interview

As a programmer, you may go through different kinds of programming tests while interviewing for jobs. The most famous and difficult one may be the whiteboard test for lots of people. Usually the interviewer will give the candidate an algorithm problem or case study and ask the candidate to implement the algorithm with his/her favorite programming language. The code to be written is not too much but it requires the candidate to thoroughly consider different edge cases. So wha...

  Tips for a better first-time hackathon experience

Here are a few things you can consider. These are by no means the only way to go about hackathons, just what's worked for me.ProjectI strongly strongly recommend doing something you haven't done before. Even if you're going into a hackathon with the intention of winning, trying something new is always fun and will keep you engaged throughout the event. Jump into mobile development, try hardware hacking, write a compiler, whatever; it's always fun to try out new things.Sticking to things you're c...

  A trap about PHP random number

The method to get random number in PHP is very simple, we only need to use rand() function. int rand ( int $min , int $max ) One function call can return the random number in a specified range. But in fact, the random number in computer is actually pseudorandomness, generally to increase the randomness, we may set a random seed before calling rand(). void srand ([ int $seed ] ) According to other language features, we should pass a time value as a parameter to the srand() function, generally...

  What Can We Learn From Dennis Ritchie?

As we noted earlier this week, one of the founding fathers of UNIX and the creator of C, Dennis Ritchie, passed away last weekend. While I feel that many in computer science and related fields knew of Ritchie’s importance to the growth and development of, well, everything to do with computing, I think it’s valuable to look back at his accomplishments and place him high in the CS pantheon already populated by Lovelace, Turing, and (although this crowing will be controversial, at lea...
