It took a while, but the era of 32-bit computing may finally be coming to a close. At least, that’s what the Ubuntu Server Team’s decision has implied with its decision to cease providing 32-bit installation CD images for the upcoming 12.10 release of the operating system. Here’s a look at this plan, and what it reveals about hardware trends more generally.
Like most major operating systems, Ubuntu is currently available in both 32-bit (i386) and 64-bit (x86_64) versions. Unless you’re a geek, you probably don’t have much reason to care about the differences between these two builds, but there are certain technical advantages to installing the 64-bit variant of Ubuntu. The catch, however, is that not all computers support 64-bit operating systems — although virtually all machines manufactured in the last few years should.
Goodbye, i386?
Ubuntu’s full support for both 32- and 64-bit architectures is set to change with the debut of Ubuntu 12.10 in October, however. In a move that highlights the increasing obsolescence of 32-bit computing, Canonical tentatively plans to release ISO images for Ubuntu server only in 64-bit form, according to the release notes for alpha builds of Ubuntu 12.10.
