The problem with Timezones by Computerphile

Have you ever had to work with timezones?
Have you experienced UTC to other timezone conversion maybe for storing data in database?
You probably used some library for that.
Can you imagine how hard it would be to implement such library by yourself?

Computerphile channel on Youtube has great entertaining video about that.

It is just crazy how different countries dealt with time over centuries.

The Computerphile channel has about 700 thousand subscriptions and they publish "videos about computers and computer stuff".

Defeating SSL by Moxie Marlinspike

"If you just look at the shape of this code, you know, there's a bug in here somewhere" - Moxie Marlinspike.

I will remember that sentence forever after watching DEFCON 17 presentation about "More Tricks For Defeating SSL"

This presentation will show you what SSL strip is and how you can notice it. Also how browsers can be fooled by exploiting a bug in SSL implementation.
