The Perfectly Legitimate Project

Grant Dobbe and Brendan O'Connor
ThotCon 0x5, April 25, 2014

When we can't use the Internet anymore---either because it's gone, or because we can't trust it---how can we share our cat GIFs, tear gas remedies, or recipes for Roasted Rodent Ratatouille? The Perfectly Legitimate Project creates a decentralized, Internet-optional system of sharing data among a group of nodes without relying on easy-to-locate mesh networks. PLP uses whatever’s available to move heavily-encrypted payloads around, including short-range wireless communications (on license-free VHF, UHF, ZigBee, or WiFi), sneakernet, or tasty (and nutritious!) carrier pigeons.

26. The Situation The Intention The Software The Hardware The Demos The Next Steps
27. Problems in Information Transfer ❖ Replication (Everyone has the data)! ❖ (De)duplication (Everyone has one copy of the data)! ❖ Linearity (Everyone has the data in the same order)! ❖ Integrity (Everyone has the right data)
28. Git Bundle $
29. Basic Workflow ❖ write all the code, hack all the things! ❖ $ git bundle create bundlename desiredbranch! ❖ copy bundle file to $SOMETHING (USB stick, burned CD, send as email attachment, whatever)! ❖ copy bundle to target machine, ! ❖ $ git clone bundlename reponame OR! ❖ $ git remote create -f bundlename remote-name OR! ❖ $ git remote update remote-name! ❖ do a git pull like you normally would $
