In this episode, our three guests answer our questions about one of the biggest community pushbacks about focusing on DEI: that of meritocracy.. Join GitHub's Senior Director, Diversity, Inclusion & Belonging Strategy Demetris Cheatham, Red Hat's Senior Manager, Global Data Privacy Clarence Clayton, and Google's Product Manager, Account Security Griselda Cuevas to learn their insights!
On The Open Road, hosts Rich Bowen and Brian Proffitt take viewers on a journey through open source communities, seeking experts to answer the questions about best practices in open source community management.

![Research Days 2022: Caching Heterogeneous Stuff in Heterogeneous Places
Caching is a classic optimization technique ubiquitous both within single hosts as well as in large distributed systems like CDNs, storage systems, databases, and data center networks. Classic solutions usually involve the omnipresent Least-Recently-Used (LRU) mechanism and its derivatives. These solutions are usually workload oblivious, and changing their configuration requires expert analysis of the system and the workload.
Recent advanced caching approaches that go well beyond LRU, which are gaining popularity, are self-adjusting and exhibit improved performance in various scenarios. We are harnessing some of the underlying design concepts to present novel caching frameworks that we are currently working on. These frameworks take into account request heterogeneity, and perform proactive caching decisions (a.k.a. speculative prefetching). We will be highlighting the design of algorithms and policies that are both dynamic and self-adjusting and consider their benefits in prominent storage system use cases.
