Upgrade to Ubuntu 11.10 (Oneiric Ocelot)

I upgraded my Ubuntu 11.04 Natty Narwhal to Ubuntu 11.10 beta 2, code name Oneiric Ocelot, on Oct. 12, before official release few days. Here are my own experience:

1. Make sure you know the admin password for PhpMyAdmin, if installed, before you upgrade. I forgot this password and it took me almost half hour to get out the infinite loop :(
2. An hour for download and another hour to install.
3. Remote desktop 'tsclient' was removed. Used 'RDesktop' or 'Remmina' instead. After using Remmina Remote Desktop client, I liked it. It's better than 'tsclient'
4. Somehow the trash icon in launchpad associated with VLC media. Uninstalled VLC resolve this issue.

Steve Jobs

Steve Jobs, the mastermind behind Apple's iPhone, iPad, iPod, iMac and iTunes, passed away on Wednesday, Oct. 5, 2011. Jobs was 56.

Apple said in a statement on its website: "Apple has lost a visionary and creative genius, and the world has lost an amazing human being. Those of us who have been fortunate enough to know and work with Steve have lost a dear friend and an inspiring mentor. Steve leaves behind a company that only he could have built, and his spirit will forever be the foundation of Apple."

Well said, I have nothing to add. But I would like to share "one more thing". One of the things I learn from Steve Jobs in WWDC 1997: “And you know the hardest thing is, when you think about focusing right, you think well focusing is about saying yes. No. Focusing is about saying no. Focusing is about saying no. And you got to say no no no. And when you say no, you piss off people… and the result of that focus, is going to be really great products, where the total is much greater than the sum of the parts.”

Rest In Peace, Steve.
