Setting up a secure VPN with strongSwan on debian

With heightening concern regarding the state of internet privacy (fuelled in part by the passing of the Investigatory Powers Act in the UK), I have set up a VPN server on the virtual server I have hosted with Mythic Beasts. This uses strongSwan and certificate-based IKEv2 authentication.

Assumptions:

  • Debian Jessie server already set up and accessible via debian.example.com, a public IPv4 of 203.0.113.1 and a public IPv6 of 2001:db8::1
  • Client username of me
  • Clients are running the latest versions of macOS and iOS (Sierra and 10 respectively at the time of writing)
  • No need to support any other operating systems (although the setup is easily translated)

For automated deployment of a similar setup, albeit Ubuntu-based and using ansible for deployment, I recommend you take a look at Algo VPN. I used that project as a basis for my configuration.

'Users hate change'

'Users hate change'

This week NN Group released a video by Jakob Nielsen in which he attempts to help designers deal with the problem of customers being resistant to their new site/product redesign. The argument goes thusly:

  1. Humans naturally resist change
  2. Your change is for the better
  3. Customers should just get used to it and stop complaining

There's slightly more to it than that, he caveats his argument with requiring you to have of course followed their best practices on product design, and allows for a period of customers being able to elect to continue to use the old site, although he says this is obviously only a temporary solution as you don't want to support both.

A picasso circle image transformation. Optimized version of: https://gist.github.com/julianshen/5829333. Use shader.setLocalMatrix() method to draw circle bitmap not from source bitmap left-top. So, we no need to create square bitmap!
