The History (and the Future) of Software


Computer History
The History (and the Future) of Software




In this lecture, IBM Thomas J. Watson Research Center's Grady Booch will take audiences on a journey that explores the evolution of software, from the time when computers were human to the present, where we live in a veritable sea of software. Along the way, Booch will look at historically interesting examples of software and study the evolution of the process and the tools of software development. Even now, the nature of software and software development is under rapid transformation, so Booch will conclude with some observations about the future of software.

Computers can be taught to play chess, drive cars, recognize faces, understand speech, and talk to us. How did we endow computers with this level of artificial intelligence? And how much further can we go in getting them to reason like human beings, think for themselves, and demonstrate common sense?

Oracle Virtual Box UUID Failed to Open Hard Disk Error





I recently copied a vdi file in my VirtualBox for Windows 7. I got the “Cannot register the hard disk C:\path\to\new\vdi with UUID {xxxx} because a hard disk C:\path\to\old\vdi already exists in the media registry (C:\path to VirtualBox.xml) error. 




The fix is easy but it takes a little bit of command line.

Open a command line in Windows.
Go to where Virtualbox is installed.
Type in: VBoxManage.exe internalcommands sethduuid "C:\path\to\new\vdi" (I drag the file from windows explorer and it sets the path for me.)

You should get something like this:

Change UUID with VBoxManager
