Work

Lost my May posts. So I don’t know how many days I’ve lost. But it’s been atleast three days of hectic work at building the blog. So I’ll count them as day 1 and start over again!

Starting anew with Nikola. After publishing this, have to figure a way to switch to Markdown

I wanted to set my command line as the default startup environment and so I went to look for the default runlevel. I coudn’t find it. That’s because they don’t exist anymore. No inittab of old, nothing. ...

I got myself a new pc to learn Linux and do all my crazy experimenting on. What’d I use as my primary OS? Why CentOS, ofcourse.
