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.
Cant connect to local MySQL server through socket /tmp/mysql.sock

Q Have you ever had the error message Can't connect to local MySQL server through socket '/tmp/mysql.sock' from your PHP program. It's one that I see quite often, but it doesn't seem all that well documented ... so what's the cause, and the cure?

A The error message seems to occur if you delete your MySQL installation and re-install - something we do very frequently during our training. You need to remember to delete the /etc/my.cnf ~/my.cnf and data and spool directories before you re-install if you want a clean start.

If you have the error message above and want a temporary fix, try connecting to "127.0.0.1" and you'll probably find it will work ;-)
