For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
Cheat Sheet - what do you need for Ruby on Rails?

Here is a "cheat sheet" of the commands you might use to install Ruby, then Gems, then Rails, then get your first application and server running.

1. Ruby

tar xf ruby-1.9.1-p376.tar.gz
cd ruby-1.9.1-p376/
./configure
make
make install


Check installation:

[root@easterton ruby-1.9.1-p376]# ruby -v
ruby 1.9.1p376 (2009-12-07 revision 26041) [i686-linux]
[root@easterton ruby-1.9.1-p376]#


2. Ruby Gems

RubyGems is a sophisticated package manager for Ruby.
See http://docs.rubygems.org/ ...
Set up gems once you've installed Ruby via:

ruby setup.rb

3. Rails

gem install rails

4. Create a framework for your first application

rails path/to/your/new/application

5. Start the server

cd path/to/your/new/application
ruby script/server


Check installation:

Browse to http://localhost:3000/
