DConf 2017 Videos

[matheus]

Hi, please could someone tell me where can I find videos from 
DConf 2017?

I pretty sure I watched them on Youtube sometime ago, but I can't 
find anymore.

By the way, I'm looking from one video where someone shows some 
"C flaws" and how to D as Better C could solve that.

I think it was the second talk in this list: 
https://dconf.org/2017/schedule/

Any idea?

Thanks.
