Apple: no ZFS for Leopard

Filed under: , ,

Much to the dismay of those Macheads who’ve started hitting size limits in Tiger’s HFS+ file system (all ten of you), Apple has confirmed to InformationWeek that Leopard will not in fact adopt the more capacious ZFS alternative as promised last week by Sun CEO Jonathan Schwartz. Senior director of product marketing for the Mac OS Brian Croll told IW point blank that “ZFS is not happening,” contradicting Schwartz’s assertion that his company’s 128-bit file system would be bringing goodies like built-in data integrity and virtual storage to the iMac and friends. Meanwhile, Sun had no comment on the matter. Of course for most users creating an average Word or Photoshop document, this reversal really doesn’t mean much, and may in fact be beneficial when we consider the higher processing demands made by the so-called ‘Zettabyte File System.” For changes in Leopard that are actually, like, real, you can check out our roundup of the new features right here.

Tzero’s WiMedia-based ZeroWire uses UWB for HD streaming

While Tzero has been at the forefront of ultra wideband technology for some time, the firm is upping the stakes even higher with its WiMedia-based TZC7200 ZeroWire chipset. The UWB semiconductor solution was designed to deliver “real-time high-definition video” either wirelessly or over cabling, and can even open new doors for “distributing entertainment content throughout the entire home using existing coax.” Reportedly, this device can pipe multiple streams of HD video through your average cable network at the tune of 480Mbps, and it boasts application integration including IP, UDP, TCP/IP, multicast, and unicast. Notably, ZeroWire is “comprised of both a Radio Frequency IC (RFIC) as well as a baseband and media access control system-on-chip,” and while the chipset is listed is being available immediately, you’ll need to contact Tzero yourself to fetch the pricing details.

Wibree is now Bluetooth’s ultra-low power wireless standard

Filed under:

Sometimes, just sometimes sanity prevails. Remember Wibree, Nokia’s proposed Bluetooth-like (but not Bluetooth) solution for short-range wireless cable replacement in low-powered devices? Well, as of this morning, Wibree, and its 10x lower power consumption (but shorter range) will become part of the Bluetooth specification for ultra low powered wireless devices. Once the spec is integrated, products like watches, toys, and even healthcare devices (er, pacemakers?) can join your Bluetooth Personal Area Network. You know, after the spec is finalized during the “first half of 2008” which will undoubtedly extend to Q3 of 2008 and then Q… ah hell, you know how it goes.
