Data linkage algebra, data linkage dynamics, and priority rewriting
We introduce an algebra of data linkages. Data linkages are intended for
modelling the states of computations in which dynamic data structures are
involved. We present a simple model of computation in which states of
computations are modelled as data linkages and state changes take place by
means of certain actions. We describe the state changes and replies that result
from performing those actions by means of a term rewriting system with rule
priorities. The model in question is an upgrade of molecular dynamics. The
upgrading is mainly concerned with the features to deal with values and the
features to reclaim garbage.Comment: 48 pages, typos corrected, phrasing improved, definition of services

Bitcoin and Islamic Finance
It is argued that a Bitcoin-style money-like informational commodity may constitute an effective instrument for the further development of Islamic Finance. The argument involves the following elements: (i) an application of circulation theory to Bitcoin with the objective to establish the implausibility of interest payment in connection with Bitcoin, (ii) viewing a Bitcoin-like system as a money-like exclusively informational commodity with the implication that such a system need not support debt, (iii) the idea that Islamic Finance imposes different requirements compared to conventional financial policies on a money concerning its use as a tool for achieving social and economic objectives, and (iv) identification of two aspects of mining, gambling and lack of trust, that may both be considered problematic from the perspective of compliance with the rules of Islamic Finance and a corresponding proposal to modify the architecture of mining in order to improve compliance with these rules
Data linkage dynamics with shedding
We study shedding in the setting of data linkage dynamics, a simple model of
computation that bears on the use of dynamic data structures in programming.
Shedding is complementary to garbage collection. With shedding, each time a
link to a data object is updated by a program, it is determined whether or not
the link will possibly be used once again by the program, and if not the link
is automatically removed. Thus, everything is made garbage as soon as it can be
viewed as garbage. By that, the effectiveness of garbage collection becomes
maximal.Comment: 22 pages; introduction improved. arXiv admin note: substantial text
