I personally use MacOS but would like to know what other people use for their research work, preferably researchers associated with Computation work. If possible do let me know the reason. This is just a survey.
Ubuntu, Debian, Fedora, CentOS, Red Hat, Suse. The reason is Linux is open source. Possible to analysate and modify. Lotof partner also use Linux. The documentation and community are big. Stable and easy to automatise. Lot of good quality tools for programing. Easy to build HPC or big server farm.
GNU/Linux on both an HPC cluster (Red Hat) and on my desktop (Debian). Reasons: lots of free software (gnu.org/philosophy/free-sw.html) scientific packages used on the cluster for research that I can build and modify, if needed.
I am using Linux as host and client OS on a virtual machine VirtualBox(VB).
It is the stable version of Debian (Mint LMDE). I also have Windows on VB - some software only exists on Windows. As a third option I can switch to the unstable version of Debian (Siduction), to be able to use latest versions of software.
Beside the trouble-free working with Debian/stable (as opposed to Windows) and the flexibility offered by VB, I appreciate that I can backup each virtual OS with all my data, and mount it again on a new laptop, making the transition to new hardware a charm.
To mention is, that you will need lots of RAM - I am using Lenovo T480s with 40G - in order to get full flexibility for switching between OSes.
im using Linux and windows. both of them completting my job I cant do all the job with one of them. in general for docking and simulation Linux is faster and easier to use but for visualation and analyze the results I cant do it without windows.
For experiment and paper writing, I prefer to use Linux.
On the other hand, for PPT and easy access of excel sheets, and drawing diagrams, I use Windows. Windows is helpful to me whenever I am working offline.
