You realize this was posed, but I didn't see what it would look like until it was too late.

Geoff Houston is a brilliant engineer - take a few minutes to read his text about the Internet of Things on the APnic blog. You will, as always with Geoff, learn new things.

"If we are heading towards an Internet of hundred billion things over the next five years, then let’s make sure that we remember past mistakes and learn from them. We really need to ensure that its not an Internet of 100 billion stupid things that can be readily co-opted for evil."

If you haven't read RFC 7435 that introduces Opportunistic Security in a simple way - go read it today. You can start with this presentation and then move on to the original text!
#MoreCrypto  
An introduction to the very important RFC 7435 by Viktor Dukhovni. After you've seen these slides, go read this document.

"We now believe we can deploy HTTPS at a
cost that, whilst significant, is well justified by the privacy returns for
our users."
Netflix adds HTTPS on all connections. Good move.

Yes, we are working today in Sweden. Somehow we exchanged this bank holiday for a National Day June 6th. Unless June 6th is on a weekend (which is the case this year), then we get the right to take another day off - but not the same for everyone. Life is interesting. I may just take the day off to think about this.

"Having an overall program for HTTP deprecation makes a clear 
statement to the web community that the time for plaintext is over -- it 
tells the world that the new web uses HTTPS, so if you want to use new 
things, you need to provide security."
RIchard Barnes - Mozilla wants to move away from a clear text web. #moreCrypto 
There's pretty broad agreement that HTTPS is the way forward for the web. In recent months, there have been statements from IETF [1], IAB [2], W3C [3], and even the US Government [4] calling for universal use of encryption, which in the case of the web means HTTPS.
