An oral history of Bank Python

I so recommend reading this article. It will provide you insight into a world that, I imagine, the majority of readers are not familiar with: Python development in the financial/banking system.

This is definitely not the first time this article has appeared on HN's frontpage, but every time it does, I re-read the article because I find the approach to software that the author describes in the article to be fascinating. YMMV.
