  Erlang Style Concurrency

Introduction On an evolutionary scale of innovation from one to ten (one being Bloomberg and Citi Group, eight being Google and Cirque Du Soleil, and ten being the company you couldn't imagine in your wildest dreams), the company I work for is about a three1. Being employed by this bastion of ingenuity affords me certain opportunities I can't get elsewhere. For example, every developer gets to interview potential...

  Use DTrace to diagnose gdb issues

A few days ago, I installed the newest 64-bit gdb program (version 7.7.1) on Solaris 10 (X86_64 platform) to debug programs. After playing with the gdb a day, I found 2 issues about gdb:(1) The "set follow-fork-mode child" command doesn't take effect. By default, after the parent process forks the child process, the gdb will track the parent process, so this command can make gdb begin to follow the child process. But this command works OK on Linux.(2) The gdb can't parse the 32-bit application c...

  Python Performance Tips, Part 1

To read the Zen of Python, type import this in your Python interpreter. A sharp reader new to Python will notice the word “interpreter”, and realize that Python is another scripting language. “It must be slow!” No question about it: Python program does not run as fast or efficiently as compiled languages. Even Python advocates will tell you performance is the area that Python is not good for. However, YouTube has proven Python is capable of serving 40 million videos...

  Prototypes and Object Orientation

David Chisnall takes a look at the two dominant paradigms in object-oriented languages (classes and prototypes) and discusses the strengths and weaknesses of each.Two terms are quite often confused when describing programming languages:class-based and object-oriented:Simula was the first class-based language. It provided classes (actually implemented using closures) as a means of encapsulating abstract data types.Smalltalk was the first object-oriented language. It provided a...

  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...

  Native Audio with HTML5

Once upon a time, audio on the web lived primarily in the world of third-party browser plug-ins like Flash, QuickTime and Silverlight. This was not a bad world, but it had its issues.For one, most plug-ins require the user to install them, but not all users are willing (or able) to install them. Also, many players built with these plug-ins are inaccessible, making it difficult for folks who use assistive technologies to access the audio or alternative content.Then there are the front-end design ...

  insertAdjacentHTML() Enables Faster HTML Snippet Injection

In Firefox 8, we’ve added support for insertAdjacentHTML(). It’s an ancient feature of Internet Explorer that has recently been formalized in HTML5 and then spun out into the DOM Parsing specification. The bad news is that Firefox is the last major browser to implement this feature. The good news is that since other major browsers implement it already, you can start using it unconditionally as soon as the Firefox 8 update has been rolled out to users.Basic Usage...

  The Greatest Developer Fallacy Or The Wisest Words You’ll Ever Hear?

"I will learn it when I need it"! I've heard that phrase a lot over the years; it seems like a highly pragmatic attitude to foster when you're in an industry as fast-paced as software development. On some level it actually IS quite pragmatic, but on another level I am annoyed by the phrase. It has become a mantra for our whole industry which hasn't changed said industry for the better. The problem is this, in the guise of sounding like a wise and practical developer, people use it as an exc...
