Comments on: Singletons are Evil 2: the Rant http://www.exubero.com/joe/2009/10/singletons-are-evil-2-the-rant/ Follically Challenged in a Hirsute World Fri, 19 Feb 2010 14:32:58 +0000 http://wordpress.org/?v=2.8.4 hourly 1 By: Paul http://www.exubero.com/joe/2009/10/singletons-are-evil-2-the-rant/comment-page-1/#comment-1191 Paul Fri, 04 Dec 2009 21:49:57 +0000 http://www.exubero.com/joe/?p=397#comment-1191 I wish I'd read this (and the links in your previous post) the day before yesterday. I had an interview yesterday where three of the four interviewers asked me about Singleton. I explained what it were but mentioned that I barely, if at all, use Singletons - in fact I couldn't remember the last time I'd coded one myself. But I struggled in explaining why I don't use the pattern. I used Singletons a lot when I started coding but over time developed an aversion, and seemed to always find ways to do what I wanted to do without a Singleton (multithreading and subclassing were a couple of problems I mentioned) - and I don't find it aesthetically pleasing, although I didn't say that. This has clarified what I knew instinctually and I now have a nice spiel showing its problems. I wish I’d read this (and the links in your previous post) the day before yesterday.
