Why do I spend time on TLS? Well, we need #MoreCrypto on the net. Join you too!
A presentation about how we can make the Internet hard to monitor - how we can and should encrypt more communication. This version includes a presentation of the TLS protocol. Changes in 2.2: Added quotes from Viktor Dukhovni's IETF RFC 7435 about Opportunistic Security

In the #funnyhatfriday  community we have a code of conduct that is very inclusive - as long as you're nice. We care about each other. This Friday we are reaching out to +Linus Nielsen  - how are you friend? We miss your hats and your cheerful API calls. Come back to us! We have updated the Code of Conduct, we have published parts of the book. What more do you want?
#Funnyhatfriday Code of Conduct. Thy shall be nice. And preferably wear a hat. Visible or not.

It's important to test out new styles and try a new image now and then. This week it's less flamingos and more glitter. Try it out. Makes you ready for the weekend! Have a wonderful ‪#‎FunnyHatFriday‬ out there!

In the ‪#‎FunnyHatFriday‬ community, we have meetings and enjoy a bit of hat folklore. Some afternoons, we listen to quotes from the book, like this one: "Wearing a flamingo hat means that you get extra good luck, especially on Friday the 13th of any month." (Book 2, section 4).

Dan highlights the end of Gtalk XMPP integration and the beginning of another walled garden inside Google. It's sad.
 
Good bye to XMPP integration... it was mostly gone, already, but this week was the final nail in the coffin...

TCP/IP Networking is still an interesting topic. We're now 130 network geeks in the Stockholm TCP/IP Geek Meetup!
(And our next meeting already have a waiting list)

In order to set up a secure http server following bettercrypto.org recommendations on Centos 6, I had to first compile OpenSSL, then compile Apache HTTPD. It took a while, but now I have a running server. Let's try if I can get a Kamailio http server with a similar setup.

Bettercrypto.org has a lot of copy/paste ready configurations for different server applications.

We got to stop all TLS proxys that break secure communication.
 
If I read this correctly, the Lenovo adware Superfish actually installs its own Root CA into the system CA store?
