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
graph is my internet usage. And, it’s great information to have, until there
is internet activity you can’t explain. more>>

I’ll Gladly Pay You Tuesday for a Hamburger Today

Author: Shawn Powers | Files under syndicated

My day job pays me on the 15th and last day of every month, unless those
days land on a weekend, in which case I get paid the Friday before. With
those rules, creating a Google Calendar event is shockingly difficult. In
fact, it’s not possible to create a recurring event with those rules using
Google’s GUI scheduling tool.

Watermarking Images–from the Command Line

Author: Dave Taylor | Files under syndicated

Us geeks mostly think of the command line as the best place for text
manipulation. It’s a natural with cat,
grep and shell scripts. But
although you can’t necessarily view your results from within a typical
terminal window, it turns out to be pretty darn easy to analyze and
manipulate images from within a shell script.

Author: Reuven M. Lerner | Files under syndicated

In my last few articles, I’ve looked
at several ways one
can apply machine learning, both supervised and

surprisingly simple—but powerful and widespread—use of machine
learning, namely document classification.

Integrating Web Applications with Apache

Author: Andy Carlson | Files under syndicated

When you deploy a web application, how do end users access it?
Often web applications are set behind a gateway device through which
end users can access it. One of the popular products to act as
an application gateway on Linux is the Apache Web Server. Although it can
function as a normal web server, it also has the ability to connect through
it to other web servers.

Manipulate Images with ImageMagick

Author: Dave Taylor | Files under syndicated

In my last
article
, I had some fun looking at the children’s game of rock,
paper, scissors, writing a simple simulator and finding out that some
strategies are better than others. Yes, I used “strategy” and
“rock, paper, scissors” in the same sentence!
