Embracing Technology Change In Scientific Software

“πάντα χωρεῖ καὶ οὐδὲν μένει” [Everything changes and nothing stands still]  - Heraclitus of Ephesus.
True 500 BC, this statement for sure holds nowadays in the software world. Whether at micro scale, when replacing a third parties library or continuously refactoring, or at macro scale, when adopting a new language, a framework or making major paradigm shift such as going parallel. Evolution is part of the development cycle.
Change can be planned, when a prototype paves the route for a production software or unexpected, when a technology breakthrough emerges during the lifespan of a project.
Although every domain is concerned by the phenomenon, scientific software raises a couple peculiarities. Often serving research, the purpose of the code itself will pivot in unforeseen directions. Meanwhile, developers, as talented as they might be, rarely come from a software engineering background and sometimes (that might be an understatement) do not consider the software building process as a relevant priority.
Embracing evolution raises challenges in multiple dimensions. We will try to cover both the technical perspective as well as the leadership one.

Perl & Hudson: continuous testing & deployment

One of the key point of Agile driven development is an infrastructure to seamlessly build, test and deploy the software at every commit.

Although lot of framework exists in the Java world, there is less available pointers on this topic with Perl. The aim of this post if to give a few practical hints on how we set up our continuous testing and deployment system using Husdon for multiple, dependent perl distributions.

Be ready, it's easy!
