I am planning to install some big softwares such as Matlab (4GB), Mathematica (4GB) on my Ubuntu partitions.

I was wondering

if I installed them on my home partition, when I reinstall Ubuntu without touching the home partition, will the softwares still be runnable after reinstallation?
what are the advantage and disadvantages of installing softwares on root partition and of on home partition?
with your answer to the previous questions, what are some reasonable plans for the sizes of root partition and of home partition? Note that I would like to learn programming in C, C++, Java, Python, Lisp, databases under both Ubuntu and Windows, and no games. My laptop has around 230 GB, where I plan to install both Windows and Ubuntu, and reserve 40 GB for Ubuntu (three partitions: swap, root and home), 110 GB for NTFS partition shared between the two OSes, 70 GB for Windows OS partition, and 10 GB that can be added to any of the above partitions. I will change my plan according to your suggestions.

Thanks and regards!
