Business is the predominant user of Tomcat, Perl and Tcl

For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.

I started using Open Source languages as a hobby about 10 years ago, but I became involved in them with my work ("Graham ... you know some Perl, don't you? .....") and these days I'm fortunate to earn my living from what was just a hobby.

Is the predominant use of Open Source languages the hobby / personal user, or the business user? How could we possibly find any statistics / measures / indicators?

I've noticed a consistent pattern in our web logs from this site - our traffic is double on a Monday - to - Friday compared to our Saturday and Sunday traffic; I can read an "ls" report of daily log files like a calendar to tell me days of the week. And the difference is even more significant as we have a noticeable "crawler" traffic from search engines indexing our pages which averages out to a constant 7-day-a-week, 24-hour-a-day spread.

Search engine terms give a further clue - that's words entered into known search engines that bring visitors to our site:
For Tomcat for every visitor on Sunday, we got 2.94 on Monday
For Perl, the ratio is 1 : 2.73
For Tcl, it is 2.63
and those are pretty significant figures; I've looked around at some of our other subjects too - and the ratio for PHP is 2.09, for Java is 2.05, and for Python is 1.88; slightly lower figures but still significant.

Overall sample size for the detailed statistics was 15000 search terms entered on Sunday and Monday last for hits on our www.wellho.net web site.

This is a page archived from The Horse's Mouth at http://www.wellho.net/horse/ - the diary and writings of Graham Ellis. 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.
