Rubbish. By this argument, the management of every corporation that
ever made a donation is going straight to jail. Acting ethically is
allowed in corporations, as in other walks of like. There is an
'ethical growth fund' in Canada that limits its investments to companies
known for 'doing the right thing'. Guess what? It outperforms the

You can trade a patent for goodwill. Goodwill is real. What is
goodwill? When you sell a corporation 'good will' is the difference
between the value of its hard assets and the price you got for it.

Tux2, or more specifically, the phase tree algorithm is useful for any
non-volatile read-write storage medium, since it gives no window of
vulnerability to crashes. It is particularly good for slow, large media
that are not friendly to journals. It is even better for flash memory
where you don't have to worry about seek time. It is useful in any
application where you need to support 'instant off' while leaving
nonvolatile memory in a known, consistent state.
