SIPB Cluedumps are informal technical talks open to the entire MIT community. They cover topics that are of general interest, such as web browsers, and topics specifically for the MIT computing community, such as Zephyr and Scripts. Cluedumps are usually one to two hours long, and we provide snacks.

[edit] Kerberos: An Introduction from the Underworld Up

Date: December 5, 2019, at 7:30 PM
Presenters: Robbie Harwood
Location: 3-370
Abstract: What is Kerberos, and how does it work? What really happens when I type `kinit`? How does a single sign-on system work? What's the difference between authentication and authorization? (And possibly related: what's with all these "permission denied" errors?) How do I use Kerberos in my projects too? And what's "cutting edge" in this technology from the 80s that keeps it in heavy use today?

[edit] Web3 and the Inter-Planetary Future of the Internet

Date: November 7, 2019, at 7:30 PM
Presenters: Nate Foss
Location: 3-270
Abstract: The current Internet is great, but it's fragile, insecure, centralized, and even censored in some places. A variety of new and old technologies exist to address these problems, and with the recent wave of interest in decentralization it looks like we're finally moving towards a new iteration of the Internet in the form of IPFS, the Inter-Planetary File System. IPFS and its surrounding technologies could take us from a location-addressed system to a content-addressed and peer-to-peer one, and bring with it all the ensuing benefits: speed, security, scalability (even to multiple planets), robustness to high latency, and reduced trust and reliance on the centralized backbone of the internet.
