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

Visa requirements for UK conferences.

First you'll want to check if you need a visa to enter the UK.

• Nationals of the EU, Switzerland, and EEA countries will not need a visa, and are free to work and conduct business in the UK.
• Nationals from some designated countries such as USA may travel for tourist or business purposes under a visa exemption. The link above will detail what documents you need to provide in order to travel under a visa exemption.
• Other nationals will need a visa.

The rules for allowable business travel under a visa exemption are covered by the same rules as those travelling under a vistor visa. If you will be travelling under a visa-exemption and the conference is covering your costs in any way you should make sure to read the relevant section below.
