  How I Develop Things and Why

I've always considered myself a bit of a software junkie. Nothing excites me more than a great piece of new software. Some of my best childhood memories are our trips to Grandma's house, where I'd have access to a computer with a dial-up connection that I'd use to obtain freeware and shareware. I'd bring 4 or 5 floppies with me and try to cram all the games, waveform editors, and utilities that I could sneaker-net home. Luckily today, excellent software written with passion oozes out of ...

  Output control functions in PHP

The Output Control functions in PHP allow you to control when output is sent from the script.

The Output Control functions do not affect headers sent using header() or setcookie(), only functions such as echo and data between blocks of PHP code. These output control functions include ob_start(0, ob_clean(),ob_get_contents(), etc. To be honest, I a...

  Two things I don’t like about Hacker News

Hacker News is a very famous IT information hub. We can find many useful links about the latest IT news and fantastic technology demos. But there are two things I don’t like about Hacker News. Maybe some of you also have the same feelings.1.  About the more link. Every time we click the more link to go to next page, there will be a unique key generated to produce the new page.

  Code Optimization Techniques for Graphics Processing Units

Books on parallel programming theory often talk about such weird beasts like the PRAM model, a hypothetical hardware that would provide the programmer with a number of processors that is proportional to the input size of the problem at hand. Modern general purpose computers afford only a few processing units; four is currently a reasonable number. This limitation makes the development of highly parallel applications quite difficult to the average computer user. However, the low cost and th...

  Those famous Emacs users

I don't think using Emacs can improve one's programming skills, I don't think some famous people used Emacs before can provide something, either. But these famous people encouraged me to learn Emacs when I wanted to give it up. Here I created a list of famous Emacs users. Most of people in this list are not famous because they developed or used Emacs, but they are famous and also use Emacs. Joe Armstrong -- Erlang's author In The Setup, Joe mentioned that "I write books using XML markup in emacs...
