Reader Privacy On The P2P Web

Vendor Lock-In

The Peer-to-peer Web is a way of thinking about distributing web content over the internet that doesn’t rely on a central point of failure. Failure sometimes means the service disappears (like the Dropbox Public folder this week). Another type of failure is failure to scale due to a bottleneck. A good example of this is data infrastructure like Amazon S3 and Google Drive. By storing all your data in one place they create a bandwidth bottleneck that they then make you pay for. For a primer on the P2P web principles I recommend the post What is the P2P Web? To quote that article, "Once integrated into a browser, these principles enable users to publish independently of services, and move between applications freely". …

Key Elements of Distributing Data

The data distribution toolkit has become a mixed bag of tools that require different skill sets and are applied for different purposes. Git, for example, is a tool that works effectively for governing data (if you learn how to use it), but it quickly becomes unwieldy for larger datasets. BitTorrent is a great solution for distributing large datasets across many machines, but torrent files are static, and can become a hassle to use with changing data. BitTorrent Sync, DropBox, and Google Drive attempt to solve this problem, but they are proprietary software that fall short when it comes to governing data amongst teams or for the public eye. Data portals like Socrata, CKAN, or are custom built employ HTTP/FTP plus a good metadata file (and a hearty group of helping hands) and continue to be the most used method for publishing open data. …

We’re happy to announce that we’ve received a $420,000 grant from the John S. and James L. Knight Foundation for a new project that we’re calling “PublicBits.” Our goal is to collect the world’s open data sources, to make their historical data available through a dataset registry at This “dataset of datasets” will become accessible through a free, decentralized, redundant, open network, inspired by BitTorrent. will use Dat, our flagship project, to craft a new, collaborative framework that breaks down the silos of data portals. Our project takes inspiration from GitHub, the popular platform that allows developers to collaboratively develop software. We plan to bring the collaborative, historical, and reusable nature of open source to the open data movement. …

Created by Max Ogden, and housed at U.S. Open Data, Dat makes it easy to create automated, reproducible data pipelines that sync. Sloan’s support will allow Dat to bring to scientific data the same automated, distributed workflows that Git brings to source code sharing. They’re funding three full-time positions for the next two years. …
