Social justice and an information democracy with free and open source software

This paper includes some thoughts on the implications of proprietary software versus free and open source software with regards to social justice, capital, and notions of an information society versus an information democracy. It outlines what free and open source software is and why it is important for social justice, and it offers three cases that highlight two salient themes. This includes a case about preference ordering and decision-making and two cases about knowing and knowledge

Cluster Winds Blow along Supercluster Axes

Within Abell galaxy clusters containing wide-angle tailed radio sources, there is evidence of a ``prevailing wind'' which directs the WAT jets. We study the alignment of WAT jets and nearby clusters to test the idea that this wind may be a fossil of drainage along large-scale supercluster axes. We also test this idea with a study of the alignment of WAT jets and supercluster axes. Statistical test neighbours indicate no alignment of WAT jets towards nearest clusters, but do indicate approximately 98% confidence in alignment with the long axis of the supercluster in which the cluster lies. We find a preferred scale for such superclusters of order 25 Mpc $h^{-1}$.Comment: Latex, 5 pages, with 5 postscript figures. To be published in MNRAS. Slight revisions to coincide with journal text.
