When the Web Split in Two
The web became delightful to browse and fundamentally harder to automate in the same architectural moment. One decision in 2010 made navigation fluid for humans while breaking programmatic access for everything else. What used to be a simple HTTP request became a timing puzzle with dozens of failure modes. The visible HTML stopped containing the actual data. Fifteen years later, every "wait for element to appear" in production web automation traces back to that choice.

One Echo This Week
Infinite scroll launched in 2006. Perfect for users. Catastrophic for crawlers.
Googlebot lands on your page, indexes what's visible, and leaves. Everything below the fold that loads on scroll? Doesn't exist. Martin Splitt finally admitted it in 2020: "Googlebot doesn't scroll." One developer discovered their entire content library was invisible to search engines beyond the navigation menu.
The operational reality: you now maintain two content delivery systems. Infinite scroll for humans. Paginated URLs for bots. A UX decision from fifteen years ago means permanent infrastructure overhead because nobody asked how crawlers actually work.
Papers That Built Infrastructure
MapReduce Made Distributed Data Processing Accessible
Backup executions for stragglers became standard practice for handling distributed system unpredictability.
The paper normalized treating machine failure as routine infrastructure reality, the assumption underlying modern cloud architecture.

CAP Theorem Formalized Distributed System Trade-offs
Network partitions force architects to cancel operations for consistency or proceed for availability.
Brewer clarified in 2012 that designers sacrifice consistency or availability only during partitions, not always.
Papers That Built Infrastructure
REST Defined Web Architecture, Not API Design
Fielding developed REST while working for W3C, deriving constraints incrementally to achieve scalability and independent deployment.
REST illustrated how to derive architecture for specific needs but became a buzzword applied blindly.
Papers That Built Infrastructure
Bigtable Established the Wide-Column Store Pattern
Built on GFS and Chubby, Bigtable showed how layering specialized systems creates infrastructure ecosystems, not monoliths.
Google Analytics stored 80 billion cells in a 200TB table, proving sparse distributed maps could handle web-scale structured data.
