Adventures in Computational Chemistry

I am still struggling with the after effects of Linux reinstallation on my system. Two major problems: 1) Firefox and openoffice is still not in English. Its giving me hard time. 2) The functions in openoffice  version of excel is not working. I am yet to sort that out. In the mean time, I desperately needed it to do simple task. subtracting values of one column from one in another column and write the difference in next column. So, I had input in this form: ------------------ 0    2.179139    0.951816 1    2.314531    1.006480 2    2.191692    0.951938 3    2.079704    0.952747 4    2.092761    0.939545 5    2.362056    0.984791 6    2.153595    0.957934 7    2.213173    0.951768 8    2.175687   ...

For some reason our administrator decided to update OS of my desktop. He installed latest version Ubuntu 11.10. My first impression was not very good. I did not find it userfriendly. Main problem is accessing different windows you open. Say, you open a firefox window with many work related tabs opned in it. This window will minimize to the left sidebar under firefox icon that also is the desktop icon to access firefox. Now, if you want open another firefox window which should have pages not work related but say personal like gmail or youtube, you click on the same icon. Instead of what you wish, the same firefox window with work related pages which you minimized few moments back reappears. So, to distinguish work related pages from personal pages is not so stright forward. One option is you open your personal page in one of the tabs in work related firefox window and then drag and drop that tab out of the window. Then it allows you to have another firefox window. But why is needs...
