In this presentation recorded during QCon London 2008, Stefan Tilkov introduces the audience to REST seen as an architectural style. He thinks that REST is not an alternative to SOA but it can serve SOA to reach its goals. Stefan also covers other related topics: HTTP, WS-*, SOAP, CORBA, RPC, enterprise, in an attempt to make the listeners understand what REST is and what is not and how it helps.

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.
Q&A: Linux founder Linus Torvalds talks about open-source identity
Kleber Rodrigo de Carvalho
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.

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

– 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.
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]

Operating systems for IBM System Z
z/OS is a 64-bit operating system for mainframe computers, created by IBM. It is the successor to OS/390, which in turn followed MVS and combined a number of formerly separate, related products. z/OS offers the attributes of modern operating systems but also retains much of the functionality originating in the 1960s and each subsequent decade that is still found in daily use. (Extreme backward compatibility is one of z/OS’s central design philosophies.)
z/OS supports mainframe staple technologies such as CICS, IMS, DB2, RACF, SNA, WebSphere MQ, record-oriented data access methods, REXX, SMP/E, JCL, TSO/E, and ISPF. However, z/OS also supports 64-bit Java, C/C++, and UNIX (Single UNIX Specification) APIs and applications, with UNIX/Linux-style hierarchical HFS and zFS file systems. z/OS can communicate directly via TCP/IP, including IPv6, and includes a standard HTTP server along with other common services such as FTP, NFS, and CIFS/SMB. Another central design philosophy is support for extremely high qualities of service (QoS), even with a single operating system instance, although z/OS has built-in support for Parallel Sysplex clustering.
z/VM is the current version in IBM’s VM family of virtual machine operating systems. z/VM was first released in October 2000[1] and remains in active use and development as of 2008[update]. It is directly based on technology and concepts dating back to the 1960s, with IBM’s CP/CMS on the IBM System/360-67 (see article History of CP/CMS for historical details). z/VM runs on IBM’s zSeries, System z9 and System z10 computers. It can be used to support large numbers (thousands) of Linux virtual machines.
Linux on System z is the collective term for the Linux operating system compiled to run on IBM mainframes, especially System z machines. Other terms with the same meaning include Linux/390, Linux on zSeries, Linux for zSeries, Linux on System z9, zLinux, z/Linux, etc.

Brazil has long been recognized as one of the powerhouses in Football worldwide. Brazil is well known for its stamina, skill and flair on the football pitch, usually leaving the rest of the world competing for second place. But far removed from these football certainties, (some Argentines may have something to say about it), is how well Brazil will fare in a newer contest now taking place across the business world — the contest to be the next location for offshoring of IT and business process services. Is Brazil a serious competitor in the “BPO/ITO World Cup”? Do they have what it takes to get to the final or do they face disqualification in the first round?
Brazil as an outsourcing destination
Analysis of Brazil as an Offshore Services Location

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

Brazil’s IT workforce offers the business savvy and technical skills to make offshoring there a worthwhile option for IT’s outsourcing needs.
Whereas India, China, Eastern Europe, and Russia get the most attention when it comes to outsourcing IT work, Brazil is fast becoming a competitive destination, offering top-quality IT talent in an intriguing location, business-wise.
