So we started counting the lines of the logfile and adding a bunch of checks …

Here's the steps I took to install the Hiawatha web server along with Nibbleblog

egrep -i 'vmx|svm' --color=always /proc/cpuinfo | sort | uniq

Output:

In this case I want it to have the IP 192.168.2.100 …

So I was curious to try out CentOS 7 on my old Gateway GT5662 desktop that's lying around gathering dust.

Some more specs on the Gateway desktop:

• Chipset: NVIDIA GeForce 6150 SE
• Processor: AMD Phenom(tm) 9500 Quad-Core Processor
