  Coding tricks of game developers

If you've got any real world programming experience then no doubt at some point you've had to resort to some quick and dirty fix to get a problem solved or a feature implemented while a deadline loomed large. Game developers often experience a horrific "crunch" (also known as a "death march"), which happens in the last few months of a project leading up to the game's release date. Failing to meet the deadline can often mean the project gets cancelled or even worse, you lose your job. So w...

  Cleansing data with Pig and storing JSON format to HBase with Pig UDF

Introduction This post will explain you the way to clean data and store JSON format to HBase. Hadoop architect experts also explain Apache Pig and its advantages in Hadoop in this post. Read more and find out how they do it. This post contains steps to do some basic clean the duplication data and convert the data to JSON format to store to HBase. Actually, we have some built-in lib to parse JSON in Pig but it is important to manipulate the JSON data in Java code before store to HBase. Apache Pig...

  40+ Techniques to enhance your php code

1. Do not use relative paths , instead define a ROOT path Its quite common to see such lines : 1require_once('../../lib/some_class.php'); This approach has many drawbacks : It first searches for directories specified in the include paths of php , then looks from the current directory. So many directories are checked. When a script is included by another script in a different directory , its base directory changes to that of the including script. Another issue , is that when a script is being ru...

  IE ActiveX(”htmlfile”) Transport, Part II

In my last post I discussed using the ActiveX(”htmlfile”) technique to provide a usable streaming transport in Internet Explorer. The solution I provided will work, but since writing the last article I’ve made significant progress in understanding why IE behaves the way it does with respect to the streaming transport. The previous solution amounted to creating an array of messages, pushing messages on that array from the htmlfile iframe, and popping messages off of the array i...

  In praise of impractical programming

Although it’s become a cultural mainstay now, I still remember when I first saw that thick book — the one with the wizard on the cover — about a school for magic where wonders are easily conjured by those who know the proper spells. Of course, I’m talking about the Structure and Interpretation of Computer Programs. There was that other book with the spells, but the “Wizard Book” sincerely claimed to teach magic. For the past few years, I’ve been ...

  How Speeding The "Most Important Algorithm Of Our Lifetime" Could Change This Modern World

Math breakthroughs don't often capture the headlines--but MIT researchers have just made one that could lead to all sorts of amazing technological breakthroughs that in just a few years will touch every hour of your life. Last week at the Association for Computing Machinery's Symposium on Discrete Algorithms (SODA) a new way of calculating Fast Fourier Transforms was presented by a group of MIT researchers. It's possible that under cert...

  JavaScript Needs Blocks

While reading Hacker News posts about JavaScript, I often come across the misconception that Ruby’s blocks are essentially equivalent to JavaScript’s “first class functions”. Because the ability to pass functions around, especially when you can create them anonymously, is extremely powerful, the fact that both JavaScript and Ruby have a mechanism to do so makes it natural to assume equivalence. In fact, when people talk about why Ruby’s blocks are different ...

  Getting started with C++ TR1 regular expressions

Overview This article is written for the benefit of someone familiar with regular expressions but not with the use of regular expressions in C++ via the TR1 (C++ Standards Committee Technical Report 1) extensions. Comparisons will be made with Perl for those familiar with Perl, though no knowledge of Perl is required. The focus is not on the syntax of regular expressions per se but rather how to use regular expressions to search for patterns and make replacements. Support for TR1 ext...
