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.
What difference does using the XHTML standard really make?
I enclose my HTML attributes in quotes - or at least when I remember, I do!
I always provide a matching close tag to go with each opening tag - except when I forget to do so, or am in a hurry
I make sure I provide an alt
attribute with each image - although sometimes I really don't know what I would say in such a tag, so I skip it
If I need an & character, I encode it as & - mind you, when I cut and paste I may miss some!
What difference does it really make to the people viewing my pages if I've got of few of these transgressions?
It was pointed out to me the other day that one of the sites I looked after didn't conform to the XHTML transitional standard in one area of the page, and there was also a specific user problem being reported. Nad it's very nice to have a "we confirm" logo there. So I took the opportunity to add a poll to the site, for regular users, asking if the changes I had made (which cleared 96 errors and 1 warning!) had made any difference to users.
I'm going to conclude that the exercise was
worth doing, as it gives me a nice warm feeling. It will make things better for the occasional person. It's suggested that it will now render faster (not sure if I believe that). It stops people telling me that can't see my page because the HTML is broken (even if the reason they can't see it is something else - like our site is blocked at their work place because it's too good and they spend too long with us). And it probably help our search engine ranking - the cleaner the code, the easier for the search engine to understand it, and the more professional it looks. (written 2009-06-18, updated 2009-06-22)
