Google Drive

There is a rumor Google will launch the Google Drive soon. Maybe next week. One said it will have 2GB. Other said it will have 5GB. Another guessed it maybe 7GB. I wonder Google can match up with Microsoft SkyDrive for 25GB of free storage or not?

Unity Launchpad error in Ubuntu 12.04 LTS (Precise Pangolin) Beta 1

In the last couple days, I encountered the Unity Launchpad error in Ubuntu 12.04 LTS (Precise Pangolin) Beta 1. I got the error dialog box displayed, closed it, got a blank screen, nothing there. No launchpad.

How I got into the terminal or launched the application? How I fixed it?

Launched the keyboard shortcut by pressed these keys together <Ctrl><Alt>T

Now in the terminal, I ran these commands:
~$ sudo apt-get update
~$ sudo apt-get upgrade

I thought the new updates would fix it. Still no launchpad. I typed this command at the terminal
~$ unity

The launchpad launched. Still some glitches. Reboot. Repeated these processes above couple times, it worked.

If you cannot open the LibreOffice document due to read error as the picture below

Un-install LibreOffice version 3.4 and install LibreOffice 3.5 will solve the problem. I got this problem when saved a file in LibreOffice 3.5 in Mac and attemped to open it in Ubuntu.

Ruby and Ruby on Rails Resources

Ruby Programming Language is a dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write. Ruby was first designed and developed by Yukihiro Matsumoto (a.k.a. Matz), a Japanese computer scientist and software programmer, in the mid-1990s in Japan.

Ruby on Rails (RoR) is an open-source web framework using Ruby programming language. Ruby on Rails released as open source by David Heinemeier Hansson, Danish programmer, in July 2004. Like many web frameworks, Ruby on Rails uses a variant of the Model/View/Controller (MVC) architecture pattern to organize application programming. As of March, 2012, there are more than 200,000 sites using Ruby on Rails per BuiltWith.com
