Availability of the code is necessary for Open Science "scientific communication relies on evidence that cannot be entirely included in publications", but "anything less than the release ofsource programs is intolerable for results that depend on computation".

“Usable line generalization for OSM roadsand routes has been a hobby project of mine …” “I’ve finally put the last piece of this project with the use of Amazons Hadoop distribution to parallelize the geometry processing.”“The entire process is exactly equivalent to this:” cat input | mapper | sort | reducer > output
“If you don’t need the results fast, save the five bucks and let it run overnight.If you don’t use spot pricing, this same job would have cost $40 slow or $78 fast.”“To try all this yourself, I’ve set up a bucket withsample data from the OSM route relations job.” http://mike.teczno.com/notes/elephants-osm-hadoop.html https://github.com/migurski/Skeletron

If everybody can do it, are we still relevant?As geospatial professionals, whatdo we make out of this situation?
