Build a blog engine in 15 minutes with Ruby on Rails (2005) [video]

- This is a pioneering 2005 screencast by David Heinemeier Hansson (DHH) demonstrating Ruby on Rails, then a brand-new open-source web framework he created. Rails introduced the "Convention over Configuration" philosophy and the MVC (Model-View-Controller) pattern to the mainstream, making it radically faster and simpler to build database-driven web apps compared to Java or PHP approaches of the time. - The "15-minute blog" demo became Rails' legendary calling card — it showed a fully functional blog (with posts, comments, and an admin interface) being scaffolded live, captivating developers who were used to much more boilerplate. - This video marked a turning point in web development: it popularized Ruby as a viable language for production web apps and launched the "Rails way" of building software, influencing nearly every subsequent web framework (Django, Laravel, Phoenix, etc.). Watching it now offers a window into a moment that reshaped the entire industry.
