I rented my server with OVH Canada. This blog is on one of the VMs that I created using KVM. Initially I did not configure VMs with IPv6 support. Actually, the IPv4 configuration is a bit more complicated than IPv6.

cURL support for CloudFlare-enabled websites
CloudFlare provides a nice protection from DDoS and other hacking activities, last year they even added a free UniverSSL package to all users.

There is a software called rsync that has the resume feature and it supports multiple protocols such as rsync:// and ssh://

Install a new nVidia card on existing Fedora system
I’ve been running Fedora for some time and I am still loving using it. Today I got a used nVidia GTX 650 Ti graphic card from my friend Lance, and I was trying to install it under my existing system structure.
We managed to get the card installed in the PC chassis and connected the power cables with the card and DVI-D cables with the monitor. When system started as normal, the whole monitor was in pink. By using Ctrl+Alt+F2 I switched to command line. The following command:

Oh-my-zsh Ctrl+R binding
The oh-my-zsh project is a fantastic zsh addon, but when vi-mode is activated, the default behaviour doesn’t have a ctrl+r reverse search.

SSL Setup
This is a personal technical note for SSL certificate setup, ensuring better scores at SSL Labs so that we have a better Internet security for our own.
