All SCO, all the time
During the last week the read-copy-update (RCU) technology has been singled out as one of IBM's contributions that SCO objects to. We ran an article looking into the origins of RCU and concluding that SCO had nothing to do with the creation of RCU. The article is a bit dated (already) but it still gives an overview of the RCU situation; a number of the reader comments are well worth reading too. In the end, however, origins matter little; SCO believes it owns everything that was ever part of a Unix system.
The company has filed a new version of its complaint against IBM, upping the damages demanded and changing many points. See this LWN article for a brief summary, a pointer to the document, and numerous comments.
Finally, should all this not be enough on SCO, the SCOvsIBM
Wiki maintained by Karsten Self is exhaustive and exhausting.
