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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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))
Predictions for the seagull population
It was the sound of Seagulls outside (what sound do seagulls make? [link]
) Well House Manor
that go me wondering yesterday "why have we got so many seagulls around here, when we're so far inland". And as I was teaching a "learning to program in PHP" day, I did a bit of research to find out something about seagull populations and population growth, and wrote a program to extrapolate forwards.
Being PHP, the results are presented as a web page - you can look [here]
to find out how many years it will be, at reported rates of growth, before there are more seagulls than people in Bristol. And you can look [here]
if you want to see the program and web page that I wrote.
As the text in my sample page says, it's dangerous to extrapolate too far - especially as factors are changing; steps are being taken (as the article referred to in the page points out) to control seagull numbers - money is being spent on this control rather than buying biscuits for internal meetings, it seems. And as populations grow at extreme rates (as been happening with seagulls), there gets to be a point where other factors start to click in.
When I woke on Sunday morning, I didn't know much about the seagull population (nor whether it's safe to eat them raw), but now I do. I marvel at facts learned every day, and I'm thankful for the opportunity to learn.
