How Pixar Stopped Worrying And Learned To Love Linux

Pixar's early computer-animation workflow ran on Silicon Graphics (SGI) Unix workstations, prized for graphical performance. As RISC workstations lost ground to cheaper, faster PCs, Pixar faced pressure to migrate but had millions of lines of internal code tied to a Unix environment and no appetite to rewrite for Windows. Rather than port to Windows NT, they chose the more POSIX-compatible path to Linux, completing the port by 2001 and fully moving the studio's render farm to Linux and x86 hardware (Xeon processors) by 2003, a move that helped establish x86/Linux as an industry standard in visual effects and animation. The piece closes by wondering why other Unix-reliant industries like CAD/CAM didn't follow suit, and why Pixar chose Linux over BSD.
