When a veteran Lisp programmer tackles a seemingly "easy" question which can be a daily and dirty task of any programmer, and presents the question as a "challenge" a beautiful thread unfolds.
When it comes to processing a text file (which is about 220 MB) which one is better: some Common Lisp implementation or Python? Is that a valid question? What are the hidden assumptions of implementations? What are the trade-offs? Does it matter if the file is Unicode encoded or plain ASCII? Does it matter what is assumed by your compiler as default? What about profiling your code? A very simple problem which led to a detailed and professional discussion among coders (including some optimization patches to the open source CL implementation SBCL, but remember that closed source CL implementation Allegro Common Lisp was also used in the original post, too, so another dimension about choosing your tools). Definitely worth a look. Details are at: http://ileriseviye.org/blog/?p=882 -- Emre Sevinc e-MBA Software Development @ Istanbul Bilgi University http://www.bilgi.edu.tr http://www.bilgiemba.net
