How did they invent the internet without the internet?  Probably with places like the Opamp Technical Books store.  I remember going there to pick up books like Oreilly’s Perl Cookbook in the 90s.  These days, I find answers to my software development and infrastructure provisioning questions on places like Stack Overflow and the ever growing number of individual software development themed  blogs out there.  Recently, this inspired me to start my own blog and to start sharing things that I’ve learned from others, or figured out on my own, in an effort to contribute back to the collective information store that I so often refer to.
