John Goerzen on Why You Should Learn Haskell

January 16 2009

Haskell can be a mind-bending language to learn, if you come from a procedural/OO mindset. It's worth the work, according to Real World Haskell co-author John Goerzen. The concepts of purity, laziness, and type safety can help you write better software in whatever language you use. read more

CGI is Dead; mod_perlite is Alive!

January 15 2009

PHP's application deployment model is difficult to beat. Perl has lacked something similar for years -- until now. Byrne Reese and Aaron Stone address the gap between CGI and mod_perl with mod_perlite, one of the features Perl 5 needs most. read more

Artificial Complexity and Internet Applications

December 02 2008

Good programmers tend to be polyglot programmers. I'm not sure that good applications tend to be polyglot applications; perhaps the way we build Internet applications is hazardous in the long term. read more

Small Apps, Loosely-Joined Into Contextual Tasks

November 20 2008

I spend too much time telling my computer how to do things when I should be able to tell it what I want to do. Perhaps it's time for declarative UIs to replace our procedural UIs. read more

Beginners Introduction to Object-Oriented Programming with Perl

November 12 2008

Perl is a great language for processing text and automating tasks. It's also a fully-capable modern programming language, with effective modularization and object oriented capabilities. Though that sounds scary, they're easy to understand (and even easier to accomplish, through shiny modern tools such as Moose and Mouse). read more

Announcing the 2008 O'Reilly Reader Survey

October 28 2008

We spend a lot of time updating our site, and we spend a lot of time agonizing over which book or article or course to feature where. Yet there's one question we need to ask regularly. How do you find what's most useful and interesting? read more
