Intel to add prestandard 802.11n to Centrino in '07: "Following Crouch on stage was David Leeper, senior principal engineer for UWB at Intel, who continued to talk about UWB's benefits and uses. 'It is a compelling technology, because you can do video streaming at very low power,' Leeper said.
Leeper estimated a full-length feature movie could be downloaded in 80 seconds using UWB. "

Good Morning Silicon Valley
Good Morning Silicon Valley: "we have recently reached a consumer price on processing power of a penny per MIPS (million instructions per second). Intel's Core Duo running at 2.13 GHz costs around $200 at retail and can perform about 20,000 MIPS."
...
• In 1977, Digital Equipment’s Vax 11/780 was a 1 MIPS minicomputer, and the Cray-1 supercomputer delivered blindingly fast execution at 150 MIPS.
• A 1999 era Pentium III/500 delivered 800 MIPS of processing power.
• A year later, in 2000, the Playstation 2 pumped out an astounding 6000 MIPS.
• Current embedded processors (like the PXA900 in [the] Blackberry Pearl, or the ARM 1136 in the Nokia N93 ...) are capable of 2000-era desktop processor speeds — in the range of 1000 MIPS, depending on battery consumption.
...
It’s 2006 now." Saunders writes. "If the current trend holds true, and we can each carry 20,000 MIPS of processing power in the palms of our hands by 2012, what will we do with that power?"

Free WebSphere wins over Java developers | The Register
Free WebSphere wins over Java developers | The Register: "It also plays against commercial software, including IBM's original WebSphere app server and BEA WebLogic.
'We see an emerging opportunity for people who want open source application servers - often that's small and medium businesses. It's a 'light functionality' option,' Jollans said. He added that IBM aims to generate revenue from WAS CE by selling support contracts, as it does for Linux.
WAS Community Edition is based on software which IBM acquired by buying Gluecode Software last year. Free to download and use, it takes the Apache software and adds components, such as web services, security, authentication, messaging and web tier clustering.
Jollans acknowledged that the commercial and community editions of WAS are not as similar as their names might suggest.
'They are different code bases - but they both implement J2EE,'"

Tree’s Blog » Why I’m Not Using LISP
Tree’s Blog » Why I’m Not Using LISP: "Only two open-source LISP implementations support Unicode: CLISP and SBCL. Both are good implementations, but neither work well on my Mac OS X machine. In particular, the FFI in the latest Clisp is busted, and neither seem to work with SLIME. However, OpenMCL does work out of the box on my G5. It works with the latest released SLIME. But it does not have Unicode support. Allegro supports Unicode, but I can’t afford that."

PRESS RELEASE Cray XT4 Supercomputer Debuts With Petascale Capability and Significant Backlog of Large Orders: "The Cray XT4 supercomputer uses up to 30,000 AMD Opteron dual-core processors running a highly scalable operating system and interfaced to the Cray SeaStar2™ interconnect chip to provide unsurpassed scalability and performance. Unlike typical cluster architectures, in which many microprocessors share one communications interface, each AMD Opteron processor in the Cray XT4 system is coupled with its own interconnect chip. Providing six links in three dimensions, the unique Cray SeaStar2 chip uses its embedded routing capability to take advantage of HyperTransport™ technology and significantly accelerate communications among the processors"

How to be a genius
How to be a genius: "Cambridge Handbook of Expertise and Expert Performance (Cambridge University Press, 2006, ISBN 052184097X).
The book essentially tells us to forget the notion that 'genius', 'talent' or any other innate qualities create the greats we call geniuses. Instead, as the American inventor Thomas Edison said, genius is 99 per cent perspiration - or, to be truer to the data, perhaps 1 per cent inspiration, 29 per cent good instruction and encouragement, and 70 per cent perspiration. Examine closely even the most extreme examples - Mozart, Newton, Einstein, Stravinsky - and you find more hard-won mastery than gift. Geniuses are made, not born."

Techworld.com - Moore's Law is dead, says Gordon Moore
Techworld.com - Moore's Law is dead, says Gordon Moore: "his law, which states that transistor density on integrated circuits doubles about every two years, Moore said this morning: 'It can't continue forever. The nature of exponentials is that you push them out and eventually disaster happens.
'In terms of size [of transistor] you can see that we're approaching the size of atoms which is a fundamental barrier, but it'll be two or three generations before we get that far - but that's as far out as we've ever been able to see. We have another 10 to 20 years before we reach a fundamental limit. By then they'll be able to make bigger chips and have transistor budgets in the billions.' "

CESARI MARA VINO DI RIPASSO vintage 2001
Have the 2003 at $16 a bottle..
While the affection for Amarone has slipped because of one nation’s foreign policy, it remains one of the world’s greatest wines. There are bottles available of straight Amarone, a slew of Ripasso (the second-tier Amarone-style wines) and indeed great white Veneto wines from Soave, all at improving prices for the consumer.
Amarone della Valpolicella is a wine so expensive and time-consuming to make that it is difficult to find a bad example of it.

Technology Review: The Trouble with Multi-Core Computers

'It's not clear yet where the right line is' between using hardware and software to solve the problem, he says, but the researchers "

Specialist servers prove their worth - IT Week
Specialist servers prove their worth - IT Week: "However, Azul servers are not cheap. Current Azul systems, based on the earlier 24-core version of the processor start at around $100,000 (£57,000) and can cost more than half a million."
The Four Hundred--Azul's Network-Attached Processing to Shake Up Server Market
The Four Hundred--Azul's Network-Attached Processing to Shake Up Server Market: "Moreover, these architectures do not scale very linearly, and the best anyone could do is to make a big 32- or 64-way SMP box like the current high-end server vendors already do. When Azul was talking about big, cache-coherent SMP scalability, it had a much larger box in mind. And that's why Azul decided to take the hard road and build a custom processor to do only those functions it would need, like garbage collection or running object-oriented programming routines, to support VMs and their application workloads.

Azul to go 48-core with Vega 2: "The first-generation Vega processor it designed has 24 cores but the firm expects to double that level of integration in systems generally available next year with the Vega 2, built on TSMC’s 90nm process and squeezing in 812 million transistors. The progress means that Azul’s Compute Appliances will offer up to 768-way symmetric multiprocessing"
