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.
MySQL server replication

Following on from yesterday's article about MySQL tuning ... there may come a time that a single server can't cope. What should you do? Consider replicating your server. This works well if you've got an application which is "read mostly" as you can then have clients reading from a series of machines, but isn't a great solution in a "write mostly" environment, as all write need to be made to the master machine. Good news is that "write mostly" environments are rare, save for logging applications.

Replication also provides additional robustness ...

There's a longer article on our web site here which tells you how to replicate your server.

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.
