Memory Management with Stephen Dolan
Stephen Dolan, KC Sivaramakrishnan, Ron Minsky, Mark Mandelmann, Simon Hughes, Matt Sullivan, Mark Blyther, Paul Lewisohn, Simon Verstraeteker
Stephen Dolan discusses advanced optimizations in the OCaml language, detailing how generational, incremental garbage collection and software pre-fetching reduce memory access latency by up to 90%. He introduces local types and unboxed representations to enable safe stack allocation and native memory layouts, thereby eliminating heap overhead for temporary values while maintaining automatic memory safety without manual lifetime annotations. The presentation concludes with a roadmap for integrating multi-core garbage collection and lifting GC barriers to support denser data structures, balancing performance with ergonomic simplicity.

Diego Saez Gil - How Pachama Uses Tech to Solve Climate Change
Diego Saez Gil, Gustav Alströmer, Mark Mandelmann
Diego Saez-Gil founded Pachama to solve the high costs and slow timelines of traditional carbon verification by deploying satellite imagery and AI for forest conservation. The platform connects corporate buyers with reforestation projects, leveraging partnerships with major satellite providers to certify under $1.5 million in carbon credits at a fraction of the historical cost. Backed by investors like Uber co-founder Ryan Graves, the company aims to scale a global marketplace that combines climate action with biodiversity tracking while advocating for stricter carbon regulations.

Joan Lasenby on Applications of Geometric Algebra in Engineering
Joan Lasenby, Craig Cannon, Mark Mandelmann, Carrie Nordlund
A joint project between the Engineering and Architecture departments at Cambridge utilizes Geometric Algebra to enable drones to reconstruct the built environment through line-based computer vision, overcoming the limitations of traditional point-cloud methods. By leveraging this mathematical framework to unify scalars, vectors, and higher-dimensional primitives, the researchers facilitate coordinate-free motion extraction and sensor fusion for complex robotic tasks. While the approach prioritizes developer productivity and geometric clarity over raw computational speed, it faces adoption barriers due to its steep learning curve despite surging interest from younger engineers.

IPFS, CoinList, and the Filecoin ICO with Juan Benet and Dalton Caldwell
Juan Benet, Dalton Caldwell, Craig Cannon, Dan Galpin, Francesc Campoy, Mark Mandelmann, Mark Blythouse, Mark Mandelbaum, Chris Broadfootnich
Protocol Labs, founded by Juan Bonet, is developing the InterPlanetary File System and its incentivized Layer-2, Filecoin, to transition internet infrastructure from centralized, location-based models to a decentralized, content-addressed network that ensures data sovereignty and censorship resistance. By replacing traditional venture capital with token-based funding models like CoinList, the organization enables long-term open-source research while utilizing Proof of Replication to create a liquid global market for unused storage capacity. This initiative aims to solve systemic inefficiencies in credit assignment and data redundancy, positioning Filecoin as a competitor to major cloud providers while fostering a new economy where protocol contributors are compensated directly through native network value.
