Baker's choice. Dense with flavour, light on filler.
Summary
A developer in San Francisco reverse-engineered Lyft's bike-sharing API after repeatedly missing available bikes during their commute. The article details the technical process of bypassing SSL encryption, accessing Lyft's private API, tracking bike availability across the city, and triggering an internal incident at Lyft. The author shares their journey of exploring the system, making a profit from their findings, and the lessons learned from this unauthorized technical exploration of a commercial bike-sharing service.
Key quotes
· 4 pulledOne cold San Francisco summer morning in Haight-Ashbury, my commute down to Market was interrupted by the sight of a lucky duck taking the last Lyft bike – again.
I should really just wake up 15 minutes earlier, I thought, fleetingly. Then instead proceeded to spend the next month reverse engineering Lyft's private API, bypassing SSL encryption, chasing loose bikes across the city, triggering an internal incident, and somehow making a profit.
I learned a lot doing this, so I'm writing it up in case you might too.
Technical summary, for the impatient (spoilers)
