Size Matters After All

Filed under
OS

Sun Microsystems is about to up the ante in the open source race, adding a 128-bit file system to its Solaris 10 operating system so that users can leave behind any worries about ever exhausting their virtual memory space.

By having a bigger bit count than everyone else, the number of unique addresses that can be created by the system for storing data and files can be larger than anyone else's. Virtual memory assumes an unlimited number of physical storage devices are available. What's needed are unique identifiers for the location of each file or data block stored, so the constraint on virtual memory is how many of those unique addresses can be created.

Linux, Microsoft Windows Vista, and most Unix systems employ either 32-bit or 64-bit file systems, which for the next 10 years are likely to be able to handle the needs of the largest computer systems.

To understand how big 32-bit systems really are, consider that 20-bit systems, once considered state of the art, could create one million unique addresses. A 24-bit system increased the number of virtual addresses to 16 million. The jump to 32-bit was a leap to four billion unique addresses, with the ability to retrieve a file or data stored at any of the locations.

The shift to 64-bit file systems, currently underway, represents a quantum jump that many experts believe will serve existing systems as long as they can run. But Sun is talking about 128-bit file system

Fixing unperceived errors in my X Windows configuration

Last week I decided to bite the bullet and upgrade X Windows to the latest version available in the main Portage tree. After rebooting, X Windows, GLX and Direct Rendering worked fine as usual. So everything was good. Well, not quite. Although the installation was working properly, there were still some long-standing messages in the X.Org log file that indicated my installation was not configured completely correctly. I had ignored them for too long and resolved to find their causes and eliminate them. Here is what I did.
