For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) 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 are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Throwing a die - exercise in Ruby

One of the exercises I often set on our open source programming courses is to ask delegates to write a program to read (from the user) up to 6 values thrown on a die, and report on the total and average. And I ask the delegates to check for errors, and allow the user to enter a special code to say they want to stop (finish early). The exercise does wonders in checking people's early understainding of the language being taught, it's input / output, conditionals and loops.

Here is one I wrote in Ruby earlier this week. You'll note:
redo to jump back to the top of a loop and restart the current iteration (as opposed to next which would take you on to the next iteration
break to get you out of a loop
• The use of ? and : as a shortform of "if ... else"
• the .to_i method to convert a string (in our example) to an integer
• use of .. to give a range that's inclusive of both ends - ... dives a range which excludes the end point
• Use of #{......} to embed the value of an expression in a text string
• If a statement is clearly incomplete on one line,the Ruby compiler / interpretter assumes it carries on onto the next line, but if it could be complete, that assumption isn't made
