How the Internet is like the Verrazano Bridge
No, the Internet has not become a series of bridges; it remains a series of tubes.
The Internet is like the Verrazano Bridge in that there are moves afoot – ill-advised moves — to change how each entity is represented through the written word.
In the case of the Internet, the influential Associated Press and its indefatigable style disciples have already decreed that the word Internet should no longer be capitalized. Many news organizations and journalists are meekly complying by demoting the Internet to the internet. As you can see, I am refusing to fall in line.
Meanwhile, in New York City, nitpicky petitioners are demanding that the Verrazano Bridge – North America’s longest such span – be renamed the Verrazzano Bridge. OK, fine, renaming may be oversating the case; they’re actually demanding the addition of a second “z” in Verrazano, despite the fact that it’s been spelled with only one since the bridge opened in 1964.

Cray gives its supercomputers 33 percent more cores with Ivy Bridge upgrade
The Cray XC30 supercomputer, now with Intel Ivy Bridge.
Cray Inc.
Cray Inc. announced today that it is now equipping versions of its Cray XC30 massively parallel processing supercomputer series with “Ivy Bridge” based Xeon E5-2300 v2 processors. The switch to Ivy Bridge—in both air and water-cooled versions of the two supercomputer lines—will give the systems more cores, better performance, and higher energy efficiency. In addition to the XC30 updates, Cray is also adding the Ivy Bridge processors to its CS300 cluster supercomputers.
The XC30 line, previously known as “Cascade,” is a hybrid next generation high performance-computing platform that uses multiple processor and coprocessor technologies, including Intel’s Xeon Phi parallel processing coprocessor. Designed for a wide array of high-performance applications, it in some ways mirrors the architecture of Tianhe-2, the Chinese supercomputer currently at the top of the TOP500 ranking of supercomputer systems. (Oak Ridge National Laboratory’s Titan supercomputer, built by Cray, uses AMD Opteron chips and NVIDIA Tesla GPUs and is currently in second place on TOP500.)
Developed by Cray in collaboration with DARPA’s High Productivity Computing Systems program, it runs on Cray’s Linux Environment and packs up to 384 processors per cabinet. Processors are paired in compute nodes that have 32 to 128 gigabytes of memory, which are connected to each other by a 500 gigabit-per-second switching fabric called the Dragonfly Interconnect.

Ivy Bridge to Offer Faster Graphics and OpenCL Support in MacBook Airs (Arnold Kim/MacRumors)
Arnold Kim / MacRumors:
Ivy Bridge to Offer Faster Graphics and OpenCL Support in MacBook Airs — As noted by CNet, one of the areas of focus in Intel’s next generation Ivy Bridge processors is the graphics processing unit (GPU). Anandtech reports that Intel expects there to be a 60% improvement in graphics benchmarks …
