How OS X “Mavericks” works its power-saving magic

Apple execs talk up the new features in OS X Mavericks. At yesterday’s Worldwide Developer Conference (WWDC) keynote, Apple made some bold claims about the future of battery life in its laptops. A new 13-inch Macbook Air, for instance, should now run a full 12 hours on a single charge , up from 7 in the previous model. Assuming that testing bears out Apple’s numbers, how did the company do it? The obvious part of the answer is “Haswell”—but that turns out to be only part of the story. The power efficiency gains found in Intel’s new Haswell CPUs should provide modest gains in battery life, and such gains were widely expected. Back in January, Intel claimed that the new Haswell CPUs featured the “largest generation-to-generation battery life increase in the history of Intel” and said that the chips were the first of its architectures designed “from the ground up” for Ultrabooks and tablets. The new chips run at lower clockspeeds and at lower wattages. Less expected was the announcement of OS X 10.9 “Mavericks” and its own focus on mobile power usage. While Apple made a few comments during the keynote about the new technologies meant to enable longer battery life, more information appeared later in the day with the separate release of a Core Technology Overview (PDF) document that offers a high-level look at some of the Mavericks internals.

New OS X uses Windows file sharing by default

@darth News about the new release of OS X, ” Mavericks ,” is trickling out as developers and other WWDC attendees post information about it to the Internet. However, hidden a bit down in Apple’s OS X Mavericks Technology Overview document is an interesting tidbit: SMB2 is replacing AFP as the default file sharing protocol for OS X. AFP— Apple Filing Protocol —has a long pedigree that stretches all the way back to the Mac’s early days (and even a bit before that). Contemporary AFP piggybacks on top of TCP/IP for transport, but it supports a few Mac-specific things that other network file protocols don’t, like type and creator codes. These don’t matter as much as they used to, but OS X’s HFS+ file system supports a pretty rich amount of metadata, and AFP transports and preserves that metadata. But AFP isn’t particularly friendly to non-Apple systems, and no operating systems other than OS X support it natively. This wouldn’t be such a big deal, except that one of OS X’s killer features, Time Machine, only works over a LAN with destinations that support AFP. This is at least in part because of Time Machine’s reliance on Unix hard links, and also in part because it has to be able to ensure that any OS X files with HFS+ specific metadata are correctly preserved. This in turn means that third-party Time Capsule devices have to rely on reverse-engineered implementations of AFP to continue functioning, and OS X updates occasionally break third-party Time Capsule devices, sometimes for weeks.

Apple unveils OS X 10.9, “Mavericks”

Apple today unveiled OS X 10.9 at its Worldwide Developers Conference (WWDC), showing off the first major revision of the Mac’s operating system since last year’s Mountain Lion . Apple has apparently run out of cat names and is now naming releases after places in California, where OS X is developed. The new OS X is thus named ” Mavericks .” Developers are being given a preview version of Mavericks today. It will be available to the general public in the fall. New features include tabs in the Finder, allowing multiple Finder windows to be drawn together in tabs. Apple is bringing tagging to documents—any tags you add to a document will appear in the Finder sidebar and in iCloud. Multiple tags can be added to each document, and these tags will allow new search capabilities. Mavericks will make life easier for users who have multiple monitors. Menus will be spread across the different displays, and users will be able to take a window full-screen on one display without disturbing the desktop on another display. HDTVs connected to Apple TV boxes can also act as displays. Mission Control has been “super charged for multiple displays,” Apple said, making it easier to drag apps and windows from one monitor to another. Read 12 remaining paragraphs | Comments

Espionage malware infects raft of governments, industries around the world

Kaspersky Lab Security researchers have blown the whistle on a computer-espionage campaign that over the past eight years has successfully compromised more than 350 high-profile targets in 40 countries. “NetTraveler,” named after a string included in an early version of the malware, has targeted a number of industries and organizations, according to a blog post published Tuesday by researchers from antivirus provider Kaspersky Lab. Targets include oil industry companies, scientific research centers and institutes, universities, private companies, governments and governmental institutions, embassies, military contractors and Tibetan/Uyghur activists. Most recently, the group behind NetTraveler has focused most of its efforts on obtaining data concerning space exploration, nanotechnology, energy production, nuclear power, lasers, medicine, and communications. “Based on collected intelligence, we estimate the group size to about 50 individuals, most of which speak Chinese natively and have working knowledge of the English language,” the researchers wrote. “NetTraveler is designed to steal sensitive data as well as log keystrokes, and retrieve file system listings and various Office of PDF documents.” Read 3 remaining paragraphs | Comments

Apple issues OS X 10.8.4 update, includes iMessage and FaceTime fixes

OS X 10.8.4 comes with a long list of fixes. Andrew Cunningham After several weeks of beta testing, Apple has released OS X version 10.8.4 for all Macs running Mountain Lion. The update fixes a long list of minor issues  and some security bugs as the OS nears its first birthday. Those hoping for major changes to OS X will have to wait until Apple’s Worldwide Developer Conference (WWDC) next week, at which Apple is widely expected to show off Mountain Lion’s successor. Quite a few of 10.8.4’s fixes are aimed at businesses. There are fixes that will help Calendar work better with Microsoft Exchange servers, compatibility and speed improvements to OS X’s Active Directory integration, improvements to compatibility with “certain enterprise Wi-Fi networks,” and fixes to issues with the SMB and NFS network sharing protocols. As ever, Apple is annoyingly nonspecific about the exact problems these updates solve, but network administrators with OS X clients may find something to like about the new update. Other squashed bugs will be of more interest to consumers. For example, there’s an iMessage fix that will prevent out-of-order messages, a fix for a FaceTime issue that would prevent calls to international numbers, and an update to Safari (now at version 6.0.5) that “improves stability for some websites with chat features and games.” Read 1 remaining paragraphs | Comments

Seat of Power: the computer workstation for the person with everything

MWE Lab’s Emperor 1510 LX—don’t call it a chair. MWE Labs Science fiction is filled with cherished seats of power, workstations that put the universe a finger-touch or a mere thought away. Darth Vader had his meditation pod, the Engineers of Prometheus had their womb-like control stations, and Captain Kirk has the Captain’s Chair. But no real-life workstation has quite measured up to these fictional seats of power in the way that Martin Carpentier’s Emperor workstations have. The latest “modern working environment” from Carpentier’s Quebec City-based MWE Lab is the Emperor 1510 LX. With a retractable monitor stand that can support up to five monitors (three 27-inch and two 19-inch), a reclining seat with thigh rest, a Bose sound system, and Italian leather upholstery, the Emperor 1510 LX looks more like a futuristic vehicle than a workstation.  And it’s priced like a vehicle, too—it  can soon be yours for the low, low price of $21,500. Tale of the Scorpion In 2006, Carpentier was slaving away as a web designer when he reached a breaking point. He was tired of his tangle of cables, the struggle to manage multiple monitors, and the horrible ergonomics that came with a standard computer desk. Inspired by the emperor scorpion, Carpentier modeled his workstation after its tail, with the monitors suspended at the stinger.

Haswell is here: we detail Intel’s first 4th-generation Core CPUs

Intel is announcing the first of its fourth-generation Core processors based on the “Haswell” architecture. Intel Intel has been releasing information about Haswell, its next-generation CPU architecture, for months now. Our coverage has already been fairly extensive—we’ve already got a nice overview of Haswell’s CPU architecture itself, along with a primer on its brand-new integrated GPUs . All we need to know now is specific product information, and Intel is finally giving us our first official taste of that today. This morning’s announcements revolve around high-end quad-core chips in the Core i7 and Core i5 families, 12 for desktops and ten for laptops. If you’re looking for specific information about U- and Y- series low-voltage chips for Ultrabooks or anything belonging to the Core i3, Pentium, or Celeron families, you’ll have to wait a little while longer. We’ll be sure to pass that information along as we have it. What we’ll do here is present a high-level recap of the CPU, GPU, and chipset enhancements Intel is introducing in Haswell. After that, we’ll break down the specific CPUs that Intel is announcing today, and the kinds of systems you’re likely to find them in. Note that all of this information is coming directly from Intel—they’re not going to out-and-out make things up, but they’re definitely going to present their CPUs in the best possible light. We’ll be putting all of the below performance claims to the test as we begin to review Haswell-based systems later this summer. Read 30 remaining paragraphs | Comments

In wake of Liberty Reserve bust, Mt. Gox will require user verification

On Thursday, the world’s largest Bitcoin exchange, Mt. Gox, announced that it would require all users to “be verified in order to perform any currency deposits and withdrawals. Bitcoin deposits do not need verification, and at this time we are not requiring verification for Bitcoin withdrawals.” The company did not provide any explanation about why it was imposing this new requirement, but it did say that it would be able to process most verifications within 48 hours. The move comes two days after federal prosecutors went after Liberty Reserve , another online currency that had notoriously poor verification. (In court documents, a federal investigator in that case included an address of “123 Fake Main Street, Completely Made Up City, New York” to create an account that was accepted.) It also comes two weeks after the Department of Homeland Security started investigating Mt. Gox over the possible crime of money transmitting without a license.

This is cool: Qualcomm shows off its Mirasol display

Engadget There have been rumors of Qualcomm’s MEMS-based Mirasol display for years now. Once advertised as the “future” of e-reader displays, the company is now showcasing its proofs-of-concept. Engadget snagged a  preview of both a 5.2-inch panel display with a 2,560 x 1,440 resolution and 577 ppi embedded into the chassis of a common smartphone body, as well as 1.5-inch panel on what looks like a smartwatch. A representative at SID Display Week, where the prototype was being shown, told the site that the displays were merely mock-ups, but that the screen will likely show up in other third-party devices. The Mirasol display is touted for its energy-efficiency. It offers a six-times-over power advantage compared to both LCD and OLED displays, which means it would be the kind of display that a smartphone would make great use of. It’s made with a micro-electro-mechanical system (MEMS) based on Interferometric Modulation (IMOD) technology, which Qualcomm says  “offer[s] users a convergent display experience with paper-like readability in almost any ambient condition, while consuming significantly less power than any other display available today.” Ars Technica alumni Jon Stokes explained  why the Mirasol display is so energy efficient in 2009: Read 1 remaining paragraphs | Comments

Mac malware signed with Apple ID infects activist’s laptop

F-Secure Stealthy Mac OS X spyware that was digitally signed with a valid Apple Developer ID has been detected on the laptop of an Angolan activist attending a human rights conference, researchers said. The backdoor, which is programmed to take screenshots and send them to remote servers under the control of the attackers, was spread using a spear phishing e-mail , according to privacy activist Jacob Appelbaum. Spear phishing is a term for highly targeted e-mails that address the receiver by name and usually appear to come from someone the receiver knows. The e-mails typically discuss topics the two people have talked about before. According to AV provider F-Secure, the malware was discovered during a workshop showing freedom of speech activists how to secure their devices against government monitoring. The malware was signed with a valid Apple Developer ID  allowing it to more easily bypass the Gatekeeper feature Apple introduced in the Mountain Lion version of OS X. If it’s not the first time Mac malware has carried such a digital assurance, it’s certainly among the first. Both F-Secure and Appelbaum said the backdoor, identified as OSX/KitM.A, is new and previously unknown. For its part, AV provider Intego said the malware is a variant of a previously seen trojan known as OSX/FileSteal. Intego continued: Read 3 remaining paragraphs | Comments
