IBM to build biggest German supercomputer
IBM and The Research Centre Juelich have signed a contract for the delivery and installation of a new IBM supercomputer at the Central Institute for Applied Mathematics (ZAM).
The new supercomputer will be based on IBM POWER4 microprocessor technology and will achieve a peak performance of 5.8 TFLOPS.
"The new supercomputer will make it possible to run models and simulations which could not be run within acceptable timeframes so far. Thus, the supercomputer will make a significant contribution to the solution of complex scientific problems" commented Dr. Ulla Thiel, Director of Scientific & Technical Computing, IBM Europe.

Microsoft to increase investment in iTV development
Microsoft, the global computer software company, has announced that it is to significantly increase spending on research and development by 20 per cent to USD5.2bn (E5.3bn) in the current fiscal year.
It is understood that one of the main investment areas that Microsoft will focus is on developing software for a wide range of electronic devices including mobile phones, personal digital assistants (PDAs) and interactive television (iTV) services.

Mr Gates reportedly affirmed the company's direction by highlighting the long-term approach that Microsoft is taking while he explained that the company was willing to take risks in its move to diversify its software strategy away from the PC and into other multimedia devices in the home.
"Ten years ago I said interactive TV was important. Ten years later I still say it's important. How much money have we made? A big negative number," said Gates.

Kosmos TV to offer Internet acess through radio
In September, Kosmos TV will begin to offer Internet access via radio to corporate clients using RadioEthernet technology.
The service will be offered in partnership with the Russian Telecommunication Network, which owns the Rosnet trademark and the companies will be focussing on small businesses, in particular to those for whom organising a dedicated line is difficult.
Kosmos TV has also plans for Internet access via Television, interactive services and MMDS, a wireless broadband technology for internet access, a project still in its beginning stages.

– Mobility– Software “subscription” (as opposed to
purchase or licensed).

Software trends lead to ...
• Network service architectures = software components accessible by other components or applications over the network by suitable protocols
• Network service therefore includes:– TCP/IP– Directory services– XML interface– SOAP, UDDI, WSDL ....

XBox online 3 months early with Linux
Microsoft's XBox Live service has been pre-empted by a Linux-based web-server invented by a group of European programmers- The XBox Linux Project.
Using a modification chip to allow the running of non-Microsoft encoded software, a version of the Linux core has been coded for the XBox. Potentially, the console may become a fully functional PC when the programmers add further software modifications.
The project has come about because of programmers' penchant for Linux, which due to its open licencing, allows them to alter the software source code.
August 2002IXDA

This is only the latest in a series of attempts to produce a functioning Linux for the console, but the first to show real results. With both the software and hardware in place, the XBox is operable over a local area network (LAN).
The Project made it clear though, that its progress was not intended to benefit piracy in any way. No Microsoft privileged code is included, and none of the developers involved in the work are allowed to use the information from the software kit.

Operating Systems
• First Microsoft OS for 64 bit processors is presented. – Supports up to 16 GB RAM and up to 8 TB
virtual memory

Microsoft develops “Windows 1984”
A new development, codename Palladium, will protect computers against virusses and spam. Also Internet shopping will become safe.
It will stop illegal copied software and downloading MP3 files.
Opponents consider Palladium to be a privacy threat (because the impossibility for anonymous surfing) and a potential Microsoft monopoly because software will have to respect new standards.
August 2002IXDA
44
IBM, Intel and HP/Compaq, who together with Microsoft form the Trusted Computing Platform Alliance (TCPA) support this evolution.
Intel and AMS already announced the development of chips usable with Palladium.
Palladium can not be installed on existing computers.

Web Technologies: XML
• W3C Standard• Data-base, operating system and device neutral language
to describe the contents of data structures• Key role for Application to Application communication
over Internet• DTD (document type definition) associated with
document, included in prologue.– Typically developed by industry consortia
• XSL (extensible style language) for stylesheets• XLL (extensible link language) to automate links between
URL’s.• XML.ORG is cathalogue and future registry and repository
of XML vocabularies.

46
Directory and discovery services• Naming, describing and finding information and
resources while managing the relation between the resources.
• Internet needs worldwide standards• LDAP (Lightweight Directory Access Protocol) first
attempt• IETF workgroup: Uniform Resource Names
Working Group defines standard for persistent and unique digital resource identifier on the internet, and, standard for comprehensive and persistent resource discovery system (URN and URI)

Applications
• New applications Web based• Old applications “wrapped” to make
accessible from browser• Front-end applications accessed via Internet
and Extranet• Back-end applications accessed via Intranet• Increasing critical role of Enterprise
Application Integration (EAI)
