For a long time, sitting on the side watching the internet play out. The latest news so far is that SOPA and PIPA have been withdrawn, will probably be re-written in some form and come back in another democratic cycle or so.
If I was US based, then I would take more personal steps in the war-on-copyright/fight-against-piracy. Alas, I’m not so I’m going to put up banners, say the right things and hold double standards on all matters.
I think I should finally weigh in here.
I think I have thought up a method of enforcing copyright that would make the RIAA, MPAA and other such organisations happy.
It just takes a bit of technical knowledge and some thought.
Let us suppose we are given a set of linear equations to solve. Here represents a square matrix of nth order and and vectors of th order. We may either treat this problem as it stands and attempt to find , or we may solve the more general problem of finding the inverse of the matrix , and then allow it to operate on giving the required solution or the equation as . If we are quite certain that we only require the solution to be the one set of equations, the former approach has the advantage of involving less work (about one-third the number of multiplications by almost all methods). If, however, we wish to solve a number of sets of equations with the same matrix it is more convenient to work out the inverse and apply it to each of the vectors . This involves, in addition, multiplications and recordings for each vector, compared with a total of about multiplications in an independent solution.

Of course, the answer depends on how your year 7 skills at algebraic manipulations are.
