Ruby DataMapper : dm-more Gem cannot be installed

Kurt on Sun, 2008-07-20 06:13.

dm-more depends on merb_datamapper (!?!) version 0.9.3 which does not appear to exist yet:

++ gem install dm-more
ERROR:  Error installing dm-more:
	dm-more requires merb_datamapper (= 0.9.3, runtime)

Not sure what to do about it.


The Unreasonable Effectiveness of Computing

Kurt on Sun, 2008-07-20 15:09.

In 1960, the physicist Eugene Wigner published an article titled The Unreasonable Effectiveness of Mathematics in the Natural Sciences , arguing that the way in which the mathematical structure of a physical theory often points the way to further advances in that theory and even to empirical predictions, is not a coincidence but must reflect some larger and deeper truth about both mathematics and physics.

Is computing the deeper “truth” about mathematics and physics and reality in general? Is the true nature of reality computational? — The universe as cellular automation operating on simple rules at very small discrete scales giving rise to emergent properties at larger scales.
