My Tech Rambling

To BM I had shared a simple piece of code to have presence integration - term for linking office communicator to any normal windows or web application - for one of the applications in my orgn. I am not going to explain it all over here - if you want that please refer to BM's blog - rather tell you how i did it. Disclaimer : We had no chance to see that code works if you have Office / Live communicator 2007. It would be good if someone could test and share this to the community I had seen Presence integration on the Sharepoint pages ( If i remember correctly its the contacts webpart) .

Goggled a lot to get a resolution and didn't land to any right spot. then browsed through all the commands that get installed with the lvm RPM. then found 2 important commands vgcfgbackup and vgcfgrestore. What I learnt. the /etc/lvm folder is quite important. backup, cache, ...
