The lifecycle of digital scientific knowledge

Like all information with a complex structure, scientific knowledge evolves over time. New ideas turn into validated models, and are ultimately integrated into a coherent body of knowledge defined by the concensus of a scientific community. In this essay, I explore how this process is affected by the ever increasing use of computers in scientific research. More precisely, I look at “digital scientific knowledge”, by which I mean scientific knowledge that is processed using computers. This includes both software and digital datasets. For simplicity, I will concentrate on software, but much of the reasoning applies to datasets as well, if only because the precise meaning of non-trivial datasets is often defined by the software that treats them.

A rant about software deployment in 2015

We all know that software deployment in a research environment can be a pain, but knowing this as a fact is not quite the same as experiencing it in reality. Over the last days, I spent way more time that I would have imagined on what sounds like a simple task: installing a scientific application written in Python on a Linux machine for use by a group of students in a training session. Here is an outline of the difficulties, in the hope that it will (1) help others who face similar problems and (2) contributes a little bit to improving the situation.
