"Intel announced yesterday that its upcoming low-cost/low-power CPUs code-named Silverthorne and Diamondville will be sold under a single brand once the products launch. The MID-centric product family will hereafter be known as 'Atom'. Consumers are obviously meant to associate the Atom brand with objects of very small size, though Intel "Quark" would have a certain ring to it."

RE: 8086 support till when?

As far as I can understand it there's actually very little overhead in supporting 8086/88 inside a modern x86 core. In most designs the x86 opcodes are translated into various core specific micro ops. 16 bit operations are still supported in 32bit mode with the 0x66/0x67 prefixes and the MMU takes care of 8086 style addressing (more accurately the CPU is set up in such a way that an 8086 task has a memory map conducive to its execution but it isn't seeing a physical chunk of memory but a chunk of memory mapped using similar techniques as are used for paging). It could be removed but the first thing that must happen is that the BIOS and boot block loaders of x86 OS's must be changed to not use any 16bit 8086 code. These machines still boot in something resembling 8086 mode.
The long and the short of it is that you might save some silicon but fractions of a percent at best with no performance increase.

"The 'Llano' processor that AMD described today in an ISSCC session is not a CPU, and it's not a GPU - instead, it's a hybrid design that the chipmaker is calling an 'application processor unit', or APU. Whatever you call it, it could well give Intel a run for its money in the laptop market, by combining a full DX11-compatible GPU with four out-of-order CPU cores on a single, 32nm processor die."

"The scuttlebutt is that IBM seemed perfectly content to wait until May to launch the Power7-based Power Systems servers, but something changed and compelled the company to move up the announcement of its first machines using the eight-core processor to today. Big Blue is not in a habit of explaining its motives or its timing for product launches, but it seems clear that IBM wanted to get out in front of a whole lot of processor and systems launches that are expected between now and the summer."

Mozilla has announced that they are going to drop support for Mac OS X 10.4 Tiger definitively. "Mac OS X 10.4 was released in April of 2005 and a lot has changed since then," Josh Aas writes, "We would like to take advantage of more modern technologies on Mac OS X and 10.4 support has been a hindrance. Where we can work around supporting 10.4, doing so consumes valuable time and effort. Neither Chrome nor Safari has to deal with this."

"The ancient bug was discovered by Google security researcher Tavis Ormandy in January 2010 and involves a utility that allows newer versions of Windows to run very old programs. Mr Ormandy has found a way to exploit this utility in Windows XP, Windows Server 2003 and 2008 as well as Windows Vista and Windows 7. The patch for this vulnerability will appear in the February security update. Five of the vulnerabilities being patched at the same time allow attackers to effectively hijack a Windows PC and run their own programs on it."

"Today, Clang completed its first complete self-host! We built all of LLVM and Clang with Clang (over 550k lines of C++ code). The resulting binaries passed all of Clang and LLVM's regression test suites, and the Clang-built Clang could then build all of LLVM and Clang again. The third-stage Clang was also fully-functional, completing the bootstrap."

With all the virtualization schemes running on top of Linux, how do they exploit the underlying kernel for I/O virtualization? The answer is virtio, which provides an efficient abstraction for hypervisors and a common set of I/O virtualization drivers. Discover virtio, and learn why Linux will soon be the hypervisor of choice.

If copyright holders want justice for illegal file-sharing, they need to start by targeting the right people: those who committed the infringement."

Sun Microsystems CEO Jonathan Schwartz, an advocate of Web 2.0, used Twitter early Thursday to announce his resignation. He was named CEO in 2006 as Sun faced a switch in strategic direction away from proprietary systems and toward open source code, including its valued Solaris 10 operating system. "Today's my last day at Sun. I'll miss it", he said in a tweet to his followers, reported the New York Times on its Web site at 1:12 a.m. Thursday. He added a bit of haiku: "Financial crisis, Stalled too many customers, CEO no more."

"The venerable GNU Image Manipulation Program is undergoing a significant transformation. The next major release, version 2.8, will introduce an improved user interface with an optional single-window mode. Although this update is still under heavy development, users can get an early look by compiling the latest source code of the development version from the GIMP's version control repository."

Why should current x86_64 CPUs intended for embedded devices support running MS-DOS directly? Or Windows XP 32 for that matter.
Build Long-Mode-Only CPUs and get rid of tons of silicon. They will certainly be much(a bit) easier tho scale down then. In the end, it could even run MS-DOS in BOCHS or QEMU if you are into that sort of thing. It's not like bussinesses will replace their remaining Windows 3.11 "Servers" with an iPod.
