THE SEARCH FOR INVARIANTS
An invariant is an observation that is widely applicable and holds over time. Finding invariants is important, particularly in an industrial setting, as they represent universal truths that can influence the design of new products and services, or improve the design of existing ones. This lecture will highlight some of the searches the speaker has conducted in the past 15 years, and describe how some of the results have been adopted in practice. The lecture will also explain some of the invariants for success in an industrial research lab.

CODE FREE OR DIE HARD
Free content. Free application hosting. Unprecedented access to customers eager to use your application - and promote it to their social networks, for free. Multiple frameworks, APIs, and development tools jostling for your attention. Users are on the move, their phones know where they are and where they've been, they're connected all the time - but their interactions with technology are faster, more fleeting, lighter on content but heavy with context. What does this all mean for developers? It means being able to operate in multiple environments simultaneously. It means writing smaller amounts of highly functional code. It means keeping pace with a consumer-facing software sector that is frantic, kinetic, and creatively destructive - now more than ever.
