POWER to the people: "Released in 2003: 276 million transistors per processor
Like the POWER3 and POWER4, the POWER5 unifies the POWER and PowerPC architectures. The POWER5 is also based on the 130-nanometer copper/SOI process, and features communications acceleration, chip multiprocessing, a larger L2 cache, a memory controller on the chip, simultaneous multithreading, advanced power management, eFuse (morphing) and hypervisor technology. IBM servers built with the POWER5 feature up to ten LPARs capable of running up to 256 independent operating systems on the higest end. POWER5 processors can be found hanging about in iSeries and pSeries servers, as well as in the first IBM entry-level UNIX/Linux box, the OpenPower? line. IBM introduced the POWER5+? processors, which are built with a 90-nanometer process similar to that used with the Cell Broadband Engine, in 2005. POWER5+ ups the clockspeed significantly -- on a smaller die"

Read two biometrics, get worse results - how it works | The Register
Read two biometrics, get worse results - how it works | The Register: "Daugman produces the calculations governing the use of two hypothetical biometrics, one with both false accept and false reject rates of one in 100, and the second with the two rates at one in 1,000. On its own, biometric one would produce 2,000 errors in 100,000 tests, while biometric two would produce 200. You can treat the use of two biometrics in one of two ways - the subject must be required to pass both (the 'AND' rule) or the subject need only pass one (the 'OR' rule). Daugman finds that under either rule there would be 1,100 errors, i.e. 5.5 times more errors than if the stronger test were used alone.
He concludes that a stronger biometric is therefore better used alone than in combination, but only when both are operating at their crossover points. If the false accept rate (when using the 'OR' rule) or the false reject rate (when using the 'AND' rule) is brought down sufficiently (to 'smaller than twice the crossover error rate of the stronger test', says Daugman) then use of two can improve results. If we recklessly attempt to put a non-mathemetical gloss on that, we could think of the subject having to pass two tests (in the case of the 'AND') rule of, say, facial and iris. Dropping the false reject rate of the facial test (i.e. letting more people through) in line with Daugman's calculations would produce a better result than using iris alone, but if the facial system rejects fewer people wrongly, then it will presumably be accepting more people wrongly."

The New York Review of Books: The Tragic Tale of a Genius: "The Bell system became operational and the Wiener-Bigelow system never saw combat. In the end, the choice of the Bell system probably had little effect on the course of the war. The big breakthrough in antiaircraft technology was the invention of the proximity fuse, a radar-controlled fuse that enabled a shell to explode and destroy an airplane nearby without directly hitting it. Without proximity fuses, neither the Bell system nor the Wiener-Bigelow system was accurate enough to shoot down airplanes reliably. After proximity fuses became available in 1944, the Bell system was good enough. "

ONJava.com: Introduction to Aspect-Oriented Programming: "Before we delve too deeply into AOP, let's introduce some standard terminology to help us understand the concepts.
Cross-cutting concerns: Even though most classes in an OO model will perform a single, specific function, they often share common, secondary requirements with other classes. For example, we may want to add logging to classes within the data-access layer and also to classes in the UI layer whenever a thread enters or exits a method. Even though the primary functionality of each class is very different, the code needed to perform the secondary functionality is often identical.
Advice: This is the additional code that you want to apply to your existing model. In our example, this is the logging code that we want to apply whenever the thread enters or exits a method.
Point-cut: This is the term given to the point of execution in the application at which cross-cutting concern needs to be applied. In our example, a point-cut is reached when the thread enters a method, and another point-cut is reached when the thread exits the method.
Aspect: The combination of the point-cut and the advice is termed an aspect. In the example below, we add a logging aspect to our application by defining a point-cut and giving the correct advice. "

Service Boundaries are Explicit: Services are expressed at their boundary and there is only ONE way to access the information and/or functionality held within a service - through capabilities exposed at the Service Boundary.

Services are Autonomous: A service should not have hard-dependencies on other services. You should design your Services to be isolated, independent and interchangeable otherwise you'll end up with a closely coupled system that is fragile and overly complex. Services should maintain all the information needed to operate in isolation so that should one or more supporting services become unavailable, your service will not fail.
Services expose Schema and Contract, not Class and Type: Services should expose their interfaces and shared information interchange structures through well understood schema, rather than a particular language or platform's representation of class or type. By adopting standards based schema can we hope to build truly interoperable systems.
Services negotiate using Policy: This is quite possibly the most valuable, most differentiating tenet. Services must comply with one another's policy requirements in order to interoperate. If you offer a secure, reliable, transacted service, a caller must also support the necessary protocols etc. This protocol negotiation should be performed dynamically which will help ensure that systems do not take hard-dependencies upon one another, and will allow Service designers to largely abstract away the actual �hook-up� mechanisms between systems focussing instead on the functional semantics of their service.

Grid Services Extend Web Services @ WSJ
Grid Services Extend Web Services @ WSJ: "Distributed systems research has a rich literature where virtualization of resources and objects is a common solution to many problems. This virtualization results in a 'transparency.' Nine of these show up again and again. They are used with respect to accessing a remote service or object. Usually the intent is that the programmer/user need not know or deal with something, but can if they want to. The transparencies are:
Access: The mechanism used for a local procedure call is the same as for a remote call. Many have argued that this is a special case on location transparency.
Location: The caller need not know where the object is located, California or Virginia - it makes no difference.
Failure: If the object fails the caller is unaware. Somehow the requested service or function is performed, the object is restarted, or whatever is needed happens.
Heterogeneity: Architecture and OS boundaries are invisible. However, objects cannot migrate without limitation. At a bare minimum communication with objects on other architectures requires no data coercion.
Migration: The caller need not know whether an object has moved since they last communicated with it.
Replication: Is there one object or many objects behind the name? The caller need not know or deal with coherence issues.
Concurrency: Are there other concurrent users of an object? The caller need not be aware of them.
Scaling: An increase or decrease in the number of servers requires no change in the software. Naturally, performance may vary.
Behavioral: Is it live or not? Whether an actual object or a simulation of the object is used is irrelevant. For example, am I talking to a host object, or a virtual host objec"

NewsForge | Linux to the rescue: A review of three system rescue CDs
NewsForge | Linux to the rescue: A review of three system rescue CDs: "System Rescue CD is the largest download at 110MB. It includes:
Linux-kernel-2.4.27-xfs
GNU-Parted-1.6.11 -- This reliable text-based partition editor is the best Linux partition tool.
QtParted and PartGui are regarded as the best free PartitionMagic clones for Linux, and you can use these two graphical partition tools without XFree86. They work with QtEmbedded and allow you to see a chart of your hard disk, create, format, delete, and modify partitions.
Partimage-0.6.4 is a Ghost/DriveImage clone for Linux.
GRUB-0.94 / LILO-22.5 -- These tools are the most common bootloaders used with Linux. You can restore your bootloader from this System Rescue CD. For example, if Windows removed GRUB, you can run GRUB from this CD and reinstall the bootloader.
File system tools
Evms 2.3 is a powerful logical volume manager.
Archiving tools tar/gzip/bzip2 are provided for Unix users. Zip/unzip, while rar/unrar/unace are provided for Windows users. "

Why Smart People Have Bad Ideas
Why Smart People Have Bad Ideas: "If you want to learn what people want, read Dale Carnegie's How to Win Friends and Influence People. [8] When a friend recommended this book, I couldn't believe he was serious. But he insisted it was good, so I read it, and he was right. It deals with the most difficult problem in human experience: how to see things from other people's point of view, instead of thinking only of yourself.
Most smart people don't do that very well. But adding this ability to raw brainpower is like adding tin to copper. The result is bronze, which is so much harder that it seems a different metal."

Cooking with Lisp
Cooking with Lisp: "Robert W. Floyd's 1978 Turing Award Lecture, hosted by Markus Fix here, and he has a great quote about Lisp:
I have seen numerous examples of the programming power which Lisp programmers obtain from having a single data structure, which is also used as a uniform syntactic structure for all the functions and operations which appear in programs, with the capability to manipulate programs as data. Although my own previous enthusiasm has been for syntactically rich languages like the Algol family, I now see clearly and concretely the force of Minsky's 1970 Turing lecture, in which he argued that Lisp's uniformity of structure and power of self reference gave the programmer capabilities whose content was well worth the sacrifice of visual form.

Supported System Configurations
Supported System Configurations: "J2SE 5.0 does not provide support for Itanium 2 -- Itanium 2 support may be added in subsequent update releases"
Myrinet Overview
Myrinet Overview: "Messages can be sent and received without system calls, resulting in measured message latencies at the MPI level with the 'E card' and 'F card' NICs of ~2.7�s with MX, and ~6.5�s with GM. Message latencies using the popular, low-cost, 'D card' NICs are ~0.8�s higher. Thanks to the OS-pass mode of operation and to protocol processing being offloaded to the firmware, the host-CPU overhead is minimal, ~0.15�s per message for sending or receiving.
For either GM or MX, and with single-port NICs, measured, user-level, one-way, data rates are ~1.98 Gb/s (248 MBytes/s), and two-way (summed bidirectional) data rates are ~3.92 Gb/s (490 MBytes/s). With the high-end, dual-port NICs, the firmware takes care of distributing and reassembling packet data across the two ports. The measured, user-level, one-way data rate of ~3.9 Gb/s (~490 GBytes/s) approaches the capacity of the two links. On hosts with good PCI-X throughput, the two-way (summed bidirectional) data rate approaches 6.4 Gb/s (800 MBytes/s)."

And they're replicated on several machines, so that if one breaks, another can serve up the information. The master index is also split up among several servers, and that set also is replicated several times. The engineers call these 'chunk servers.'
As a search query comes into the system, it hits a Web server, then is split into chunks of service. One set of index servers contains the index; one set of machines contains one full index. To actually answer a query, Google has to use one complete set of servers. Since that set is replicated as a fail-safe, it also increases throughput, because if one set is busy, a new query can be routed to the next set, which drives down search time per box. "
