- code is law on the internet, but can our law be interpreted as code?
- law is a set of instructions that is interpreted by lawyers
- ~1.4m sentences
- we can look at references to different regulations and acts - i.e. extract the dependency graph
- we can use all the graph + code complexity and health metrics to analyze law
- some core components are simply too complicated for humans to interpret -- unintended ripple effects
- formal proofs for laws?

Camille Fournier, CTO Rent the Runway.mov - pbell
- CTO's primary team are the executives; engineers are second
- CTO is representing the engineers, we need to hold them to a high standard
- your job is not to code; you're not the smartest developer; your job is to connect the business goals to engineering execution
- you shouldn't relinquish managerial duties; managing people is what allows you to yield influence and shield the team

Scaling Uber's Real-time Market Platform
- previous matching algorithm leveraged available supply only (small subset of data)
- goal of new matching algorithm is to leverage future ETA + supply predictions (e.g. this car should be available in x minutes); requires matching against the full available supply database
- world is divided into tiles via s2 algorithm: each tile has a unique integer ID
- 1 mile radius is covered by small number of s2 tiles
- matching router performs fanout to hosts responsible for each tile; all tiles are served via a hash ring and service can be scaled on demand
- everything is made "retryable" because availability is more critical then full consistency
- migrated away from per-city sharding because managing that many cities became a burden
- built own protocol, which is similar to Finagle: multiplexing, routing, logging, etc
