Why User-Mode Threads Are Often the Correct Answer

Concurrency is the problem of scheduling simultaneous, largely-independent tasks, competing for resources in order to increase application throughput. Multiple approaches to scalable concurrency are used in various programming languages: using OS threads, asynchronous programming styles (“reactive”), syntactic stackless coroutines (async/await), and user-mode threads (fibres). This talk will explore the problem, explain why Java has chosen user-mode threads to tackle it, and compare the various approaches and the tradeoffs they entail.

Finite of sense and infinite of thought: A history of computation, logic and algebra

The talk will cover the long history of computation, logic and algebra, and the relationship between the three, from Classical times to the 20th century, starting out as a single discipline and then growing apart in the early 20th century. Rather than being surprising, this relationship stems from a single — yet fascinating — line of inquiry into the essence of thought, guided by a particular ancient aesthetic. We will focus on the importance of language and meaning in that evolution, and discuss the philosophical revolution that broke away from the linguistic tradition and completely changed how we view thought, computation and meaning.
