Since 2010, we have been editing articles for this column from all over the world. The theme has essentially been the same -where does software appear, in what quantity and using what technologies ? We have had a vast range of responses all the way from the realms of the very large -space exploration, to the very small -the search for the Higgs boson. In between, we have touched on many practical systems such as air-traffic control, banking in emerging nations, navigation and general automobile systems.
