| 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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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)) |

The music of the stock market
Over this weekend, I have come to realise just how similar the music is to high finance (and that I should take a day off occasionally!). I love the range of applications that I look at ... and on Saturday, I was looking at sequences of stock values at regular intervals, whether they were going up and down over periods, and other factors such as percentage changes and how erratic the movements were. On Sunday I was dealing with the music of composers who's names were new to me, but well know to my delegate, and looking at their ups and downs, rates of change, and how erratic they were. In fact, it took me a few hours to "twig" the connection ... and its struck me like a bolt from the blue when I realised that both my city-type and my musician had split their data sets into bars of a certain length. Today was Python, yesterday was Lua, and tomorrow will be C and C++; I don't know the details of tomorrow's application, but even if it turns out to be web log analysis, I expect we'll be spitting our data down into a series of equal length periods and looking for trends between them.

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. Please check back via our main site for current courses, prices, versions, etc - any mention of a price in "The Horse's Mouth" cannot be taken as an offer to supply at that price.
