Linux founder Linus Torvalds talks about open-source identity

Linus Torvalds is a regular visitor to Australia in January. He comes out for some sunshine and to attend the annual Linux.conf.au organized by Linux Australia. He took some time out to speak to Rodney Gedda about a host of topics, including point releases, file systems and what it’s like switching to GNOME. He also puts Windows 7 in perspective.

Ubuntu and its creator

In December, hundreds of these controversial software developers gathered for one week at the Google headquarters in Mountain View, California.

They came from all over the world, sporting many of the usual signs of software mercenaries: jeans, ponytails, unruly facial hair and bloodshot eyes.

All the fuss at the meeting centered on something called Ubuntu and a man named Mark Shuttleworth, the charismatic 35-year-old billionaire from South Africa who functions as the spiritual and financial leader of this coding clan.

Created just over four years ago, Ubuntu (pronounced oo-BOON-too) has emerged as the fastest-growing and most celebrated version of the Linux operating system, which competes with Windows primarily through its low, low price: $0.

Java and e-commerce

I was looking for an e-commerce solutions based on Java.

First all I searched on google and I found the article on TechNewsWorld regarding Is E-Commerce Ready for Open Source?.

After that I read about KonaKart: Free Java-based online shopping cart on InfoQ. Thefore so far, KonaKart looks like the best e-commerce solution using java platform or the only one.

If you know any other open source Java solution for e-commerce, leave a comment here.

I will be testing KonaKart soon and I’ll sharing my experience here.

Thanks

IBM System Z

– System Z on IBM
– System Z on Wikipedia

IBM System z, or earlier IBM eServer zSeries, is a brand name designated by IBM to all its mainframe computers.

In 2000, IBM rebranded the existing System/390 to IBM eServer zSeries with the e depicted in IBM’s red trademarked symbol. But because no specific machine names were changed for System/390, the zSeries in common use refers only to one generation of mainframes, starting with z900.

Since April 2006, with another generation of products, the official designation has changed to IBM System z, which now includes both[1] older IBM eServer zSeries, the IBM System z9 models, and the newer IBM System z10 models.

Both zSeries and System z brands are named for their availability — z stands for zero downtime. The systems are built with spare components capable of hot failovers to ensure continuous operations.[2].

Supports the z/OS, Linux on zSeries, z/VM, z/VSE, z/TPF, and MUSIC/SP operating systems.

Read more about Operating System for IBM System Z.

Models (chronological order)

The older S/390 IBM mainframe servers are considered history since support for the last S/390 compatible version of z/OS (1.5) was dropped on March 31, 2007.[3]

zSeries mainframes:

  • z900 (2064 series), for larger customers (2000)
  • z800 (2066 series), entry-level, less powerful variant of the z900 (2002)
  • z990 (2084 series), successor to larger z900 models (2003)
  • z890 (2086 series), successor to the z800 and smaller z900 models (2004)

System z9 mainframes:

  • z9 Enterprise Class (2094 series), introduced in 2005 initially as z9-109, beginning the new System z9 line
  • z9 Business Class (2096 series), successor to the z890 and smallest z990 models (2006)

System z10 mainframe:

  • z10 Enterprise Class (2097 series), introduced on February 26, 2008
  • z10 Business Class (2098 series), introduced on October 21, 2008

InfoWorld’s guide to following your job overseas

Tech job moving abroad? Offshore yourself with it! InfoWorld’s guide to following your job overseas.

If your job is moving overseas, maybe you should move with it. Many American IT workers have looked with increasing worry as programming and datacenter jobs moved to India, China, Eastern Europe and elsewhere as companies seek cheap labor and Internet connectivity has made offshoring a plausible business option. Or perhaps your job is staying in the U.S., but being handled by an H1-B-visa-holding immigrant or a foreign consultancy such as Tata Consulting Services and Wipro that tends to import its own workers. While some companies have found offshoring to have more costs than savings when management and quality issues are factored in, it’s clear that IT jobs have been globalized and will stay that way… more

What’s new in the GNU Compiler

In the last few years, the GNU Compiler Collection (GCC) has undergone a major transition from GCC version 3 to version 4. With GCC 4 comes a new optimization framework (and new intermediate code representation), new target and language support, and a variety of new attributes and options. Get to know the major new features and their benefits.

GCC is the cornerstone of development in both the open source and closed source worlds. It’s the enabler of architectures and operating systems. When a new processor appears, its success depends on a version of GCC that will support it (a back end that can generate code for it). GCC is also the enabler of Linux®. Linux as an operating system is widely successful because it is run on so many different architectures. Once again, a port of GCC to the target environment enables Linux to be ported and run on it. Without trying to put too fine a point on it, GCC paves the way for Linux and embedded development.

But GCC can’t just sit still. New processor architectures continue to appear, and new research finds better ways to optimize and generate code. So GCC moves forward and has now matured into its fourth major release. This article explores the fundamental changes in GCC version 4 to show you why—if you haven’t switched yet—the time has come to use the compiler standard.

You can read the complete article at developerWorks.
