Cassandra is a highly scalable, high-availability, high-performance wide column store also based on Google’s BigTable design.

Use Cases, Questions and Answers

Stack Overflow:

Stack Overflow (PouchDB):

  • Architecture of an app when using CouchDB/PouchDB
    1. If I have multiple users with there own authentication, how can I make sure that the users get access to only their data? And will I still have 1 database on server end? – Answer: Ref to guide in the pouchdb-authentication README.
    2. PouchDB on the client side can be in sync with a remote PouchDB. But when an application is build with Javascript how do you make sure that people are not inserting data into PouchDB by ‘hacking’ the client-side Javascript? – Answer: You cannot prevent users from writing bad data (they can always open up the console and do whatever they want), but you can use something like pouchdb-validation to re-use your validation function on the client side.
    3. Would the use of a backend be gone in these kinds of setups? And if you want to have an API for 3rd party, you just put for example an Sails.js backend around the CouchDB? – Answer: Some people write PouchDB apps without any backend (just using pure CouchDB/Cloudant/Couchbase), whereas others like to mix the database with a server architecture of their choice. …
  • How do I query X specific documents all at once using an index with pouchdb?
  • PouchDB from Nodejs generate auth credentials? – Answer: pouchdb-authentication is designed for use in the browser, but you can use nano to interface with CouchDB from Node.

Job opportunities for people with CouchDB skills

Time to relax!

  • “attempts to realize the values of liberational technology can produce unanticipated, even self-sabotaging effects. … Although mainstream tech culture has drifted from the more radical premises of liberational technologies, free and open-source software (F/OSS) has certainly creatively troubled liberal values of proprietary ownership, bringing intellectual copyright and other information restrictions under greater scrutiny. Despite such potential, open source software never wholly escapes capitalism and is thus subject to a pattern of exclusions” – Tripping Over Our Bootstraps: Open Source Ecology and the Promise of Liberational Technology
  • “They are known as téléchargeurs, or downloaders, and they operate as an offline version of iTunes, Spotify and Pandora all rolled into one. / It was a question as dumb as my simple Nokia phone. A cellphone is a digital Swiss Army knife: flashlight, calculator, camera and, yes, audio player. Mali’s homegrown, offline digital music has created a space for sharing songs that is in many ways more vibrant than the algorithm-driven way music is so often experienced in the United States — more personal, more curated, more human.” – A Music-Sharing Network for the Unconnected
  • “There’s probably more than one way of using color codes as data. But one thought I had was that they could be an interesting way of identifying racialized depictions of comic book characters in a reproducible manner.” – Race, Gender, and Skin Color Dynamism in Comic Books
  • “CEO Nick Van Weerdenburg says, “In building as a diverse company in one of the world’s most diverse cities, I always imagined we would do fine in hiring and building a strong female core. However when we stopped and looked at the facts once we hit 50 people, we realized we needed to be more proactive to reach our goals- not just as a company but as an industry.” – Initiative announced for Women in Tech
