If you have attended a technical course from IBM, SUN or any other large training organisation, you may have been instructed by John Gwilliam.
For the last 17 years, John has been actively involved in Unix consultancy and training and has worked for, and with, a number of large companies. However, the last few years have seen many changes and challenges in this marketplace and unfortunately, not necessarily for the better. Shrinking budgets, diminishing margins and increased competition have put additional pressure on training departments who now need to be more careful than ever how and where their money is spent.
