Two interesting papers by Thomas Green
I don't know if anyone of you knows about Thomas Green, but I have just
stumbled across his website and found two of his papers very
interesting. They are:
* "Cognitive Approaches to Software Comprehension: Results, Gaps and
* "Ironies of Abstraction"
Here is a quote from the conclusions section of the first paper:
"Conclusion: People do what's easiest
[...] people use the easiest resources available. Historically, the
development of languages and environments has made control flow
information much more accessible than other types, so the
'control-flow-first' model is a good approximation of most existing
environments. But the way forward in designing environments and in
understanding comprehension, if my interpretation is correct, is to
offer programmers the chance to choose from a richer array of resources.
That means we need to improve access to other types of information,
especially that which is 'upstream'. We can do that by changing either
the language or the working environment [...]."
And here is a short one from the second paper: "Indeed, many successful
computer-based systems make very few calls for abstractions, and may
perhaps be successful for that very reason."
All best and a happy new year,
