Cassius is a clojure wrapper around cassandra's thrift interface. It treats cassandra as a big mutable nested hashmap and provides the following abstractions:

• cassandra data and schema can be represented as values and clojure maps.
• keyspaces, column families, rows and columns can be abstracted as nested map layers
• supercolumns are just one extra level of nesting

The library has been used for both mocking and for higher level abstractions on top of cassandra. 

Regarding defects in human-built systems, the term "bug" appears to have been coined by Thomas Edison in 1876 to describe problems in his systems. Bug has been defined as  "an unexpected defect, fault, flaw, or imperfection".

One group had positive words like “love” and “nice” filtered out of their News Feeds. Another group had negative words like “hurt” and “nasty” filtered.
