Book Review: Mac OS X Maximum Security

"Assuming that 'because it's a Mac, it's safe' is no longer wise" is probably one of this book's most important themes. It has been my experience that too many Mac users "know" that OS X is secure and therefore they have nothing to worry about. This book shows just how wrong that attitude is.

If Linus Snubs New GPL, Is That it For ‘Open Source’?

"Linus Torvalds doesn't want to change the Linux kernel's software license, and he said so again last week. For good measure this time, he threw in some inflammatory remarks. "I literally feel," wrote Torvalds, "that we do not, as software developers, have the moral right to enforce our rules on hardware manufacturers. We are not crusaders, trying to force people to bow to our superior God." Since the crusades were a foreign adventure responsible for the deaths of tens of thousands, that's not the most diplomatic response, and FSF counsel Eben Moglen refused to be drawn into retaliation when we contacted him for comment."

Microsoft Security Service to Ship in June

Microsoft plans to ship a new security product in June, charging $49.95 a year to shield up to three PCs against viruses, spyware and other cyberthreats, the company said on Tuesday. Called Windows OneCare Live, the product marks Microsoft's long-anticipated entry into the consumer antivirus market, which has been the domain of specialized vendors, led by Symantec and McAfee. Microsoft announced its intent to offer antivirus products in June 2003 when it bought Romanian antivirus software developer GeCad Software.

Sculley’s Dream: the Story Behind the Newton

LowEndMac has an in-depth article on the origins of one of Apple's most elusive products: the Newton. "Sakoman's end goal for Newton was to create a tablet computer priced about the same as a desktop computer. It would be the size of a folded A4 sheet of paper and would have cursive handwriting recognition and a special user interface. To run the enormously demanding handwriting recognition software, the tablet would have three AT&T Hobbit processors." By the way, as most BeOS fans like myself know, AT&T's Hobbit processor has been part of another elusive product.

IBM Thumbs Nose at Heat Concerns, Kicks Power6 to 6GHz

IBM has carved out a renegade path for the upcoming Power6 processor, opting to crank the chip's GHz much higher while rivals shy away from major clock speed boosts with their products. The Power6 chip will run between 4GHz and 5GHz and has been shown to hum away at 6GHz in the lab. IBM reckons that some process technology breakthroughs have allowed it to kick GHz higher while still keeping heat and power consumption issues under control. All told, IBM claims that Power6 will be twice as fast as competing server processors from Intel, AMD and Sun.

Intel Shows off Multi-Threaded Xeon Chip

Chip firm Intel presented a 65 nanometre dual core multithreaded Xeon with a shared 16MB on die level three cache at the Solid State Conference. The Xeon has 1.328 billion transistors, a 1MB unified L2 cache per core, and has a die size of 435mm2. It delivers 3.4GHz at 1.25 volts and 150 watts TDP, and comes with a 667 and 800MT/s three load front side bus interface. This chip is compatible with existing chipset designs and Intel claims it has the largest cache and device count for an X86 processor.

Firm Shows off Flexible Metal Foil Display

"A firm is showing off a full colour active matrix OLED display prototype at a show today. Universal Display Corporation, which has had part funding from the US Department of Defence, will talk at the Fifth Annual Flexible Displays and Microelectronics conference in Phoenix today. The firm will show off a four inch diagonal display and demo it running full motion video. The display is .1mm thick, and weighs only six grams, compared to a glass LCD which would weigh about 20-30 grams. The firm said that using a metal foil helps thermal and mechanical durability."

Novell Releases Xgl Enhancements, ‘Compiz’ Compositing Manager

"Novell is announcing its contribution of the Xgl graphics subsystem and the 'Compiz' compositing manager to the X.org project. These enhancements open up a whole world of hardware acceleration, fancy animation, separating hardware resolution from software resolution, and more. As a result, Linux desktops will become more usable, end-user productivity will increase, and Linux is firmly positioned at the forefront of client computing technology." Videos and screenshots are included in the press release. And on a related note, Dan Winship of Novell has explained on gnome-desktop-devel why Novell worked on all this behind closed doors-- and this also applies to the striking similarity between Novell's mockups from December and Nat Friedman's videos. The changes made to GNOME will all be released back.

Intel, AMD Spar Over Virtualization

Intel and AMD once again are angling for leadership in virtualization, technology that increases a computer's efficiency by letting it run multiple operating systems simultaneously. Intel is expected to declare this week that its Virtualization Technology is mature enough for testing and about three months away from prime time. But AMD, whose rival "Pacifica" technology won't debut in processors until midway through this year, is trying to set its own technology as a standard for virtualization of computer communications, an element not present in Intel's VT.

Linux-based Motorola Cell Phones Frustrate Third-Party Devs

Motorola first announced its intention to migrate its mobile "smart" phones to embedded Linux in 2003. The first such phone to reach the market was the A760 in the fourth quarter of that year. Today there are a dozen or so models (differing product numbers in different markets and minor hardware variations lead to different counts), but there are still no significant ecosystems for third-party applications or developers. Is Motorola's switch to Linux a hit for the company but a miss for end users?

Why Apple Really Ditched PowerPC

"Apple wants to make their switch to Intel chips seem like a no-brainer, but the reality of it was a lot more complicated than just faster chips for Macs. Apple's claims of their Intel systems being '4-5x faster' than their PowerPC systems is a little much to swallow, especially with Intel Macs landing in users' hands and failing to live up to the hype. So if these Intel chips aren't really that much faster than the G5, why did Apple make the switch? The answer to this question is a lot more interesting than what Apple's telling you."

CLI Magic: ifup, ifdown, ifstatus

"I've always assumed that ifup and ifdown were conditional commands that performed their assigned duties only if the interface device in question was up or down, as the command might be. I was dead wrong. I blame my mistake on being a programmer, rather than being stupid, but it's simply too close to call. The if in ifup, ifdown, and ifstatus is not a programmer's if - it's an abbreviation for interface. On the off chance that I'm not the only one who has misunderstood these commands because of their rather iffy names, here's what they really do and how they are used."

The Rise of Real-Time Linux

"New real-time Linux enhancements open a whole new world of possibilities for Linux, ranging across the latest 3G technologies and as near as the mobile handset in your pocket. The purpose of modifying the Linux kernel with real-time functionality: to dramatically reduce interrupt and task preemption latency, thus enabling the 2.6 kernel for use in high-performance multimedia applications and those requiring extremely fast, task level reliable control functions. Real-time Linux has come a long way - where is it now and where is it heading?"

Do We Need Sidebars? Jim Allchin Thinks so

"Windows Vista will eventually sport what has been called a 'sidebar' - a kind of taskbar-like user interface element designed to sit on the right or left side of a display and offer 'heads-up' information on a customizable basis. When we last checked in on the Vista Sidebar at CES, we saw a number of widgets (or gadgets) running on the sidebar, including a small picture frame, an RSS list/interface, weather information, and more. The idea, generally speaking, is to give prominent spacing to tasks and information services that are, in theory, so frequently referenced that it makes sense to prominently display them on your desktop, alongside or on top of your other application windows."
