No really security related but, a good story...
"Like many schools, Grace Lutheran School struggled to keep up with the cost
of computer technology. With 250 students and an annual technology budget
of $15,000, Principal Dennis Fangmann had to be creative to keep his 60
classroom Pentium I and Pentium II computers running. Most of his budget
was being used instead to keep the 16 staff computers and Windows network
server current, leaving little for student computer upgrades."
