Chromium hacker Hexxeh has released a faster, USB-bootable build of Google's Chrome OS called Chromium OS Zero. Meanwhile, ArsTechnica interviewed Google's Engineering Director for Chrome OS, Matthew Papakipos on the past and future of Chrome OS. Hexxeh's final build of Chromium OS Zero follows earlier, well-regarded releases of versions including Chromium OS Diet and Cherry. Based on the open source Linux Chromium code that Google began to release in late November, with the goal of releasing a final Chrome OS for netbooks later this year, Chromium OS Zero promises major speed improvements "for many users," according to Hexxeh's blog announcement.
