On Intention

Note: This series and words of opinion are also aimed at the Student Planet.

OK, I’ve changed my mind.

Before, I talk tactics, let me tell you something about intention.

All intention means to me is, “I, Decide!”

On Capturing Value; my newest mental model


I’ve found it difficult to figure out why I did not make money (or at least intentionally make money, not counting my lucky breaks) as I expected to, in the old consulting gig. This, despite the fact, that I knew I was smarter than the average bear when it came to my field of work.

And that same fear still remains1 as I pivot careers. I know I’ll pick up stuff with programming. I know I’ll get fluent. But will I be able to make a comfortable living?

Booting CentOS into Graphical or Command Line Mode by default


Ok, now that I’ve installed CentOS, I decided to install X Windows. And like Rip Van Winkle, I learnt that a lot has changed in 20 years :)

A windowing environment was easy to install …

sudo yum groupinstall "Gnome Desktop"

and the trusty old startx & gave me a Windowing Environment (which I have yet to explore)

However, switching permanantly to graphics mode (or vice versa) wasn’t so easy. 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.

The init scripts of old have now been replaced (for quite a while) by systemd. And while it’s old (most Linux distributions have adopted it for nearly 3-5 years now) it’s still new to me :)1

So, systemd targets something called targets2 instead of runlevels. (Haha, see what I did there? :P) Targets to my mind involve a collection of settings in a file all relating to … something … a service.

You could group all of your network stuff in a network target, or like I needed it all your runlevel settings in a command line target or a graphical target.


So a quick search led me to the systemctl get-default command which gives my my default target

Another search gave me the multi-user target to use if I wanted a multiuser command line environment.

So to switch all I had to do was, systemctl set-default

Et voila!

If I ever wanted my graphical environment back as a default setting, systemctl set-default

And Bob, as they say, is my uncle.
