Anatomy of the Linux kernel - History and architectural decomposition

Anatomy of the Linux kernel

The Linux® kernel is the core of a large and complex operating system, and while it's huge, it is well organized in terms of subsystems and layers. In this article, you explore the general structure of the Linux kernel and get to know its major subsystems and core interfaces. Where possible, you get links to other IBM articles to help you dig deeper.

Given that the goal of this article is to introduce you to the Linux kernel and explore its architecture and major components, let's start with a short tour of Linux kernel history, then look at the Linux kernel architecture from 30,000 feet, and, finally, examine its major subsystems. The Linux kernel is over six million lines of code, so this introduction is not exhaustive. Use the pointers to more content to dig in further.

SCA: 1.0 and OASIS - Bobby Woolf's dW Blog

From Bobby Woolf: WebSphere SOA and J2EE in Practice

Monday April 02, 2007

• SCA: 1.0 and OASIS

Service component architecture (SCA) has reached some important milestones.

In "SCA V1.0 Publication & OASIS Standardization Intent Announcement," the OSOA announces SCA v1.0, to go with SDO 2.1. The specs have now been submitted to OASIS for ratification as a standard.

I've talked about Service Component Architecture (SCA), the new programming model designed specifically for SOA, and Service Data Objects (SDO), a programming model for portable data. SCA is built into WebSphere Process Server and is being standardized by the Open Service Oriented Architecture (OSOA) organization, a collaboration of a dozen top software vendors including IBM.

You can get more links on my wiki; Open Service-Oriented Architecture is a good place to start.

Oracle Service Registry 10.1.3.1 now available

Oracle SOA Suite 10g Release 3 (10.1.3.1.0) Downloads: "Oracle Service Registry 10g Runs on all certified platforms (80 MB)"

** WHAT'S NEW IN ORACLE SERVICE REGISTRY 10.1.3.1 **

Key enhancements other than infrastructure changes include:

* Support for the Oracle XML-based lightweight security provider

* Use of Oracle data sources, meaning that RAC support is now provided out-of-the-box

* Support for the following non-Oracle databases:
** Microsoft SQL Server 2005
** IBM DB2 8.0 +
** Sybase ASE 12.5 +

* An embedded Oracle Lite database. This configuration is supported on Windows only and is suitable for demonstration purposes only.


** SUPPORTED ORACLE APPLICATION SERVER VERSIONS **

Study Finds Open Source Benefits Business

Study Finds Open Source Benefits Business

By Thomas Claburn

'Free' software makes economic sense.

Floss for economic health. That's the conclusion of a newly released European Commission studyOpen Source Software (Floss) on the European IT sector. on the impact of Free, Libre, and

The EC study, conducted by UNU-Merit, a research institute of the University of Maastricht in the Netherlands, finds that the use of open source software adds 263 billion Euros to the European economy and "the number of employees among firms contributing code to Floss projects is at least 570,000."

It also says that open source software programmers, nearly half of which are based in Europe, volunteer least 800 million Euros (roughly $1 billion U.S.) worth of labor.

The report calls for "correcting current policies and practices that implicitly or explicitly favor proprietary software" by offering fairer R&D incentives, supporting standardization, avoiding vendor lock-in in education settings, equitable tax treatment for open source contributors, and encouraging partnerships between businesses and the open source community.

The report estimates that the Floss-related share of the economy could reach 4% of European GDP by 2010.

"By providing a skills development environment valued by employers and retaining a greater share of value addition locally, Floss can encourage the creation of [businesses] and jobs," the report says.

That's a perspective shared by Richard Gorman, a venture partner at Silicon Valley VC firm Bay Partners, which invests in open source companies. "Open source is clearly a major trend and is clearly an economic stimulus for the economy today," he said. "The reason we like the open source business model is that it's a way of entering markets and solving customer problems in a very effective way, both from a control and an economic perspective."

Some of the report's findings and recommendations may rankle leading proprietary software makers such as Apple and Microsoft.

One policy recommendation seems particularly applicable to Apple and the ties between the iPod and iTunes Music Store: "Explore how unbundling between hardware and software can lead to a more competitive market and ease forms of innovation that are not favored by vertical integration."

And one of the report's findings is that users of Microsoft Office are no more productive than users of OpenOffice. "We also investigated the productivity of the employees in using Microsoft Office and OpenOffice.org," the report says. "Office suites are widely used and are a good test bed and representative for a comparison on issues like effort and time spent in the daily routine of work. Delays in the task deliveries may have a bigger impact than costs on the organization's management. Our findings report no particular delays or lost of time in the daily work due to the use of OpenOffice.org."

The report, however, stops short of recommending businesses switch to free applications such as OpenOffice because "employees may perceive that their work is under-valued using 'cheap' OSS products." It says organizations should consider that migrating away from proprietary software might have implications beyond cost.

Microsoft maintains that the total cost of ownership for Windows software is less than Linux and continues to host dozens of case studies, white papers, and customer testimonials to that effect on its Get the Facts Web site.

But Gorman insists the open source software makes economic sense. "It's a very good business model for entering large, existing markets and taking significant share, and creating significant customer and investor value," he said. "If you're an incumbent competing with a new company that's an open source company, it's very difficult to adjust or change your business model to be competitive. Usually by the time they end up adjusting, it's too late."

News Story: "Mathematician who challenges established ideas --Antara Das

Even quantum mechanics is a provisional theory: Roger Penrose

# He was delivering the NIT convocation address
# Says the Big Bang, in a certain sense, is not the beginning

PHOTO SUSHANTA PATRONOBISH

Mathematician Sir Roger Penrose and BARC director S. Banerjee at the second convocation of the National Institute of Technology in Durgapur on Saturday.

DURGAPUR: For renowned mathematician and physicist Sir Roger Penrose, it is a depressing thought that we may be close to the Theory of Everything that will explain all the mysteries associated with the universe, down to the minutest detail.

'A final theory, if it comes, must have beauty and simplicity — something that I have not yet come across,' he said, while delivering the convocation address at the second convocation of the National Institute of Technology (NIT) here on Saturday.

Hailing from a distinguished family of scientists and mathematicians, Sir Roger had been playing with geometrical objects from the age of 10, said Bikash Sinha, Chairman of the Board of Governors, NIT, while introducing the former.

Controversial views

Known for his controversial views on the relation between physics and consciousness,

Sir Roger came across as one who did not venerate established ideas. 'Even quantum mechanics is a provisional theory, which has to be replaced by a great theory,' he said.

'This is not just my own contention. It has also been stated by Einstein, Schrodinger and Dirac.'

While asking the graduating students to challenge the conceptual basis of established theories and advance alternate world views, he said his own ideas about the Big Bang, the singularity supposed to mark the beginning of time, had considerably changed.

'The Big Bang, in a certain sense, is not the beginning,' he said, adding 'the big final stage may also be the initial stage — when there is only radiation left and the universe loses track of its scale.' It has to be mathematically proved though.

Explaining through fun

Sir Roger, famous for the Penrose tiling, said there was no clear demarcation between scientific work and fun.

He often found that it was often easier to explain with simple diagrams what could not be explained by complex calculations.

Flip-Flotsam

Ever wondered what happens to your footwear after you're finished with it? This original documentary traces the fantastic journey of the flip-flop.

Filmed over a two-year period, this startling and uplifting film takes an ingenious look at the lifecycle of the flip-flop. It's especially noteworthy for the beauty of its photography and editing. We guarantee you will have never seen anything like it.

The flip-flops' journey begins in the factories of Mombasa, where 20 million pairs a year are made. Worn-in and worn-out they are taken to the cobblers, who specialise in flip-flop maintenance. But some are too damaged to be repaired and lie rejected. Every May, the monsoon rains wash the rubbish to the ocean. The downpour enables the discarded cast-offs to make their escape.

Brushing shoulders with other marine wanderers, they are swept along by the ocean's current. Sea borne for years, their buoyancy and resilience are put to good use by ocean hitch-hikers. They eventually come to rest on distant coastlines.

Islanders search the beach for flip-flops washed up by the sea. Later, they ingeniously carve life back into the tide's offerings.

The islanders prize the discarded flip-flops as a valuable resource. They are carved into dolphins, turtles and mobiles, fuelling a new cottage industry, which provides precious income for many families. Newly transformed, the flip-flops begin yet another journey. Leaving the quiet shores of Kiwayu, they are transported back to the shop-lined shores of Mombasa, where their first journey began.

Blog Censorship by the Indian Government ?

Blog Censorship by the Indian Government ?: "Over the weekend, news slowly started trickling in that some Indian bloggers were having difficulty viewing blogspot and typepad blogs. Mridula was one of the first bloggers to comment on this issue.

Neha took up the issue and asked people to check whether they were able to access these blogs. Slowly, a list of Indian ISPs that had these blocks in place began to emerge.

Various bloggers called their ISP call centers and asked them about the block. Some ISPs were clueless about the block, some mentioned that the government had ordered that the sites be blocked.

Shivam Vij contacted the Computer Emergency Response Team (CERT-IN) and recived a terse response.
'Somebody must have blocked some sites. What is your problem?'

Chacko's sources indicates the block might be directed at specific blogs being used by terror units to communicate. I am reminded of Anand's article cautioning the loss of civil liberties in the wake of the terrorist attacks.
