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.
The HTML++ Metalanguage

What's the difference between a language and a metalanguage?

A language is a single specification - a way of describing a series of actions or how some particular data is handled. Whereas a metalanguage is a way of specifying a series of languages to a particular pattern.

An example? HTML is a language. There are different flavours (slightly) but basically it's a single language. What I descibe as HTML++ is a metalanguage - a way of adding to HTML to make it rather more that just HTML. Examples of HTML++ metalanguages include JSP, PHP, ASP, Rails, Eruby, EmbPerl, SSI; all differently languages as you need different compilers / interpretters to handle them, but all extending basic HTML in a similar way.

In the same way, XML is a metalanguage, and implementetations of it include XSLT, RSS, and many more from SOAP to Tomcat configuration files.

Update - January 2010 - we have added an optional Ruby on Rails day to our Ruby courses because it is becoming so popular - see [here]
