Business models based on the compiled list at http://news.ycombinator.com/item?id=4924647. I find the link very hard to browse, so I made a simple version in Markdown instead.

Build your own private, encrypted, open-source Dropbox-esque sync folder

Prerequisites:

  • One or more clients running a UNIX-like OS. Examples are given for Ubuntu 12.04 LTS, although all software components are available for other platforms as well (e.g. OS X). YMMV
  • A cheap Ubuntu 12.04 VPS with storage. I recommend Backupsy, they offer 250GB storage for $5/month. Ask Google for coupon codes.

Software components used:

  • Unison for file synchronization
  • EncFS for folder encryption

Avro better than X

For info, I gave a talk about it : http://www.slideshare.net/jwinandy/data-encoding-and-metadata-for-streams/17

a few points :

  • a reference to a schema is 64 bits (with hashing) or 32 bits if you use a coordination store (like Kafka + Camus does).

    • It's not a real waste of space, because you can use this reference for multiple payloads.
  • field renaming is well supported. In Avro you read your data with not one, but 2 schemas :

    • the one that was used to encode the data with (easy, it's around the data as metadata),
    • and the one you want to use to read your data.
