Presentations
James Haworth Wheatman
I built ErrorScript: TypeScript with "Safe" Exceptions. Unhandled exceptions and dropped promises become part of the type system and raise compile-time errors.
It works. It feels native. And it probably shouldn’t exist.
This talk explores what ErrorScript reveals about how we model failure in code, how language design influences behaviour, and the trade-offs that make this feature unlikely to be adopted.
Luke Sargeant
Right now you can build faster than ever. You have ‘Everything as a Service’; Hundreds of AI agents at your disposal with no workers' union. And JavaScript runs on virtually every internet connected device on the planet. Scary huh?
In this talk I’ll share practices I’ve seen work as an IC, a manager, and a manager of managers, and what remains important when zooming out from line by line implementation.
Luke Sargeant is an Engineering Lead at vega-alts.com - a Series A startup Building the Alternative in private markets.
