Experimentation in system-oriented courses is often challenging, due to the raw and complex nature of the underlying infrastructure. In this work, we present our findings in teaching cloud computing to upper-level and graduate level students with GENI testbeds that are in use by the distributed systems community. The possibility of giving students practical and relevant experience was explored in...
Recall that combinatorial 2s-designs admit a classical lower bound on their number of blocks, and that a design meeting this bound is called tight. A long-standing result of Bannai is that there exist only finitely many nontrivial tight 2s-designs for each fixed s≥5, although no concrete understanding of ‘finitely many’ is given. Here, we use the Smith Bound on approximate polynomial...
