| This is now an archive web site. Some is still relevant as at February 2026 but some is purely of historic interest. Lisa and I (Graham) are now fully retired from IT training.We have made many friends over 30 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Apache, Linux and Solaris/SunOS too. Our training notes are out of date, but with upward compatability some examples remain operational and relevant. You are welcome to make use of them "as seen", at your own risk. We now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We remain active, enjoying the times that we are retired but still healthy enough in mind and body to do things! I am also active in many other area and still look after a lot of web sites - you can find an index ((here)) |

Easy example - data record to object and object to data record mapping in Ruby (written 2015-11-21)
From the Ruby course just finished - an example of an application that reads through a data file, passes comments through unaltered, converts valid data lines into objects which it updates and writes back in place. The whole busisness of mapping data records to objects and objects back to data records is an interesting one; typically, the "forward" mapping might be done in a factory method, and the back mapping within the object's to_s method.

Every attempt was made to provide current information at the time the page was written, but things do move forward in our business - new software releases, price changes, new techniques. So much so, and it's so long ago that we are retired
