I currently have the flu. Not the "sorta queasy" stomach flu, but the full
out Influenza with fever, aches and delirium-ridden nightmares. Bouts
of crippling illness tend to be my only chance to play games. Thankfully,
since I'm such a terrible gamer, being sick doesn't really hurt my skills
The "Internet of Things," or IoT, has the potential to change the way we interact with the devices and objects in our homes and lives.
The IoT is the idea that all of the devices and gadgets that you interact with could be connected to the internet.
I love Bitcoin. Ever since I first discovered it in 2010 and mined
thousands of them, I've been hooked on the technology, the concept and
even the software. (Sadly, I sold most of those thousands of Bitcoin
when they were less than a dollar. I'm still kicking myself.) One of
the frustrations with using Bitcoin, however, is that the blockchain
has gotten so large. more>>
The first time I used vi was in a college programming course. It was the
default editor on the computer lab's UNIX systems we used to compile our
assignments. I remember when our professor first introduced vi and
explained that you used the hjkl keys to move your cursor around instead of
the arrow keys. more>>
One of the most crucial pieces of any UNIX-like operating system is the
init dæmon process. In Linux, this process is started by the kernel,
and it's the first userspace process to spawn and the last one to die

With Hiera, you can externalize your systems' configuration data and
easily understand how those values are assigned to your servers. With
that data separated from your Puppet code, you then can encrypt sensitive
values, such as passwords and keys.
DivvyCloud, a fast growing McLean, VA cloud management technology company, has been included in

management architectures are becoming easier to use and implement. more>>
Lightweight virtual containers with PID 1.
In this article, I demonstrate a method to build one Linux system
within another using the latest utilities within the systemd suite of
management tools. The guest OS container design focuses upon BusyBox and
Dropbear for the userspace system utilities, but I also work through
methods for running more general application software so the containers are

...than to understand Linux permissions! Honestly though, that's
not really true. Linux permissions are simple and elegant, and once you
understand them, they're easy to work with. Octal notation gets a little funky,
but even that makes sense once you understand why it exists.
Users and Groups:
One ongoing question kernel developers face is the best way to delete data so no one else can
recover it. Typically there are simple tools to undelete files that are deleted
accidentally, although some filesystems make this easier than others.
