This is probably OT, but how much is MIX/MMIX still used in the new books coming out? Volume1 had MIX code for everything, and IIRC by Volume3 it wasn't as pervasive.
Does Volume4 have MMIX code for all algorithms presented?
Philip Greenspun (of the famous "tenth rule of programming"!) had an interesting question [1]:
Question: would it be illegal for 23andme to relocate to Singapore, for example, and have people mail DNA samples to Singapore and then email them the results? The company’s web site indicates that customers in Singapore (and a bunch of other countries) can send their DNA to have it tested. Would the FDA have jurisdiction to prevent a Singapore-based company from accepting packages from consumers in the U.S.?
