The one I cover here is gromacs (http://www.gromacs.org). It should be available for your distribution via its package manager. more>>

Avogadro

Basic Chemistry on the GNOME Desktop

I've realized I've missed out on a huge area of computational science—chemistry. Many packages exist for doing chemistry on your desktop. This article looks at a general tool called avogadro. It can do computations of energy and gradient values. Additionally, it can do analysis of molecular systems, interface to GAMESS and import and export from and to several file formats. more>>

Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
