There are so many great use cases for versioning. Handling code deployments, document edits, and database snapshots are just a few immediate uses that come to mind. Normally, a versioning system is another segment within a database, but it can be so much more when you think of it through the lens of immutable data and DHT (distributed hash tables) technology. So, today, we’re going to build a stream of consciousness note-taking app with version history. This will be different than other notes apps as it will have just ONE note that the user can edit over time, removing information or adding information.

RSS feeds are a largely underestimated feature of the web nowadays — at least outside the circles of geeks. Not only they are much more omnipresent than many think (every single respectable news website provides at least one feed); not only they empower users with the possibility of creating their own news feeds and boards through aggregators, without relying on the mercy of a cloud-run algorithm; but their structured nature (under the hood an RSS feed is just a structured XML) offers the possibility to build automation pipelines that deliver the content we want wherever we want, whenever we want, in whichever format we want. IFTTT is a popular option to build custom logic on RSS feeds. It makes it very intuitive to build relatively complex rules such as “send me a weekly digest with The Economist articles published in the latest issue”, or “send a Telegram message with the digest from NYT every day at 6am”, or “send a notification to my mobile whenever XKCD publishes new comics”.
