Few programmers really restrict themselves to one language, since they all have their strengths and weaknesses.

Java is useful, but also fairly strict and rigid; you get less choices about the way you write your programs. You're forced to use OOP and nothing but OOP since literally everything is an object. You're forced to use try/catch since so most things don't bother returning errors any other way. And so-on. It's a whole lot to learn at once just to make the simplest possible program.

I haven't managed to come to grips with Python myself. The way whitespace is actually important in Python code is pretty unusual in a programming language.

Perl is pretty popular and powerful and has lots of modules available. It's also kind of eccentric, being a weakly-typed language with complex data structures and OO.

I'd actually suggest shell scripting, with a modern shell like BASH, so you can get yourself acquainted with variables, arrays, loop structures, functions, and I/O without having someone's pet programming methodology crammed down your throat.

Shell scripting doesn't have data structures though, unfortunately, and can't do a lot of things directly. So once you've learned the basics you could try a more flexible language like C. Properly-written C code can work on lots of different systems.

This is the book I remember most from my college days. I kind of regret giving it away now.

If Ubuntu will work on a virtual machine for you, that'll be good enough for teaching purposes, and better than things like Cygwin which still technically run inside Windows. Might not be the best for teaching though, it's autoconfiguration is a bit overzealous. Perhaps Fedora or SuSe?

NAME
photon - generates photo albums SYNOPSIS
photon [OPTIONS] [PATH] DESCRIPTION
Photon generates clean, yet configurable, static HTML photo galleries. All of the work is done from the command line, and the resulting output can easily be configured by changing the template files found in /usr/share/photon/templates. To create a new template (skin), first create a new directory: mkdir -p ${HOME}/.photon/templates/my_theme/ Then copy the contents of /usr/share/photon/templates/photonv1/ to this new directory. Photon only needs three files to build pages: index.html used to display the content of a folder image.html used to display the page for an image movie.html used to display the page for a movie If a file is missing, then photon will throw an error and will not run. HOW TO BUILD A GALLERY
Quick start $ photon -o myoutputdir /photos Use the gimp plugin $ photon --resize-plugin=gimp -v -o myoutputdir /photos Change the size for all images and the thumbnail and keep the original photo $ photon --sizelist=0,1600x1200,800x600 --thumbsize=320x240 -o myoutputdir /photos Create a gallery from your custom template (skin) $ photon -k my_theme -o myoutputdir /photos See photon help $ photon --help OPTIONS
