For 2023 - 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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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))
Some Ruby lesser used functions
Tidying up (as one does after the recent server move!), I came across a list of functions in Ruby which are important at times, but not exactly top of the list ... and I thought I would share them here - with a few words on each - in the hope that I might save someone a lot of hairpulling at some stage in the future!
- teminate your program
- register code to be run when you exit
- register a class to be loaded only when used
- return the current execution stack
- evalute the given string as ruby code
- exit and run the given command in its place
- create a child process (could be a whole module on this!)
- perform string substitution (see under regular expressions)
- convert a block into a proc object
- same as gets but throws exception at eof
- checks for availabilty of inputs without blocking
- suspend operation for n seconds
- seed the random number generator
- run system calls and commands
- set a signal handler (e.g. if you need to catch ^C) (written 2008-07-26)
