Making Programs Forget

Map Date/Time: 2022-09-21 06:00pm Location: PDX Code Guild - Portland 97201

Our next paper is "Making Programs Forget: Enforcing Lifetime for Sensitive Data" by Kannan, Altekar, Maniatis, and Chun.

[https://www.usenix.org/legacy/events/hotos11/tech/final_files/Kannan.pdf](https://www.usenix.org/legacy/events/hotos11/tech/final_files/Kannan.pdf)

This should make a nice contrast to our last paper which was about how to preserve the changes made by a group of distributed editors. Modern software needs to both remember and forget!

As before we'll be meeting at the PDX Code Guild.

A Conflict-Free Replicated JSON Datatype

Map Date/Time: 2022-07-06 06:00pm Location: PDX Code Guild - Portland 97201

For the first meeting of the reactivated chapter of Papers We Love: PDX we are going to discuss "A Conflict-Free Replicated JSON Datatype" by Martin Kleppmann and Alastair R. Beresford.

[CRDTs](https://en.wikipedia.org/wiki/Conflict-free_replicated_data_type) are relatively recent data types designed for collaborative, distributive editing of shared documents, even while sometimes offline.

This paper should be a good introduction to CRDTs. You can find it at: [https://arxiv.org/pdf/1608.03960.pdf](https://arxiv.org/pdf/1608.03960.pdf).

The event will be held at the [PDX Code Guild](https://pdxcodeguild.com/).
