Creating an Application-Based Terminal Session

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.


Watermarking Images–from the Command Line

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.


Integrating Web Applications with Apache

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.


Unsupervised Learning

In my last few articles, I’ve looked into machine learning and
how you can build a model that describes the world in some way. All of
the examples I looked at were of “supervised learning”, meaning
that you loaded data that already had been categorized or classified in
some way, and then created a model that “learned” the ways
the inputs mapped to the outputs. more>>
