Sysadmin 101: Patch Management

Author: Kyle Rankin | Files under syndicated

A few articles ago, I started a Sysadmin 101 series to pass down some fundamental
knowledge about systems administration that the current generation of junior
sysadmins, DevOps engineers or “full stack” developers might not
learn otherwise.
I had thought that I was done with the series, but then the WannaCry
malware came out and exposed some of the poor patch management practices still more>>

Analyzing Song Lyrics

Author: Dave Taylor | Files under syndicated

I was reading about the history of The Beatles a few days ago and bumped into an
interesting fact. According to the author, The Beatles used the word
“love” in their songs more than 160 times. At first I thought,
“cool”, but the more I thought about it, the more I became skeptical about the figure. In
fact, I suspect that the word “love” shows up considerably more than 160

Live Stream Your Pets with Linux and YouTube!

Author: Shawn Powers | Files under syndicated

Anyone who reads Linux Journal knows about my fascination with
birdwatching. I’ve created my own weatherproof video cameras with
a Raspberry Pi. I’ve posted instructions on how to create your own
automatically updating camera image page with JavaScript. Heck, I even
learned CSS so I could make a mobile-friendly version of BirdCam that
filled the screen in landscape mode.

Creating an Application-Based Terminal Session

Author: Andy Carlson | Files under syndicated

One of my first exposures to computers in a work environment was using a Wyse
terminal to access a console-based application for data entry. It wasn’t until a
while later that I learned about terminals in UNIX and how they work. Once I
understood it, I wanted to create my own self-contained application that was tied
to a telnet or SSH session.

In my last few articles, I’ve been exploring the capabilities of ImageMagick,

Novelty and Outlier Detection

Author: Reuven M. Lerner | Files under syndicated

In my last few articles, I’ve looked at a number of ways
machine learning can help make predictions. The basic idea is
that you create a model using existing data and then ask that model to

Tracking Down Blips

Author: Shawn Powers | Files under syndicated

In a previous article, I explained the process
for setting up Cacti
, which is a
great program for graphing just about anything.
One of the main things I
