Life’s certainties include death and taxes but also the advancement of the GNU/Linux® operating system, and the last two kernel releases did not disappoint. The 2.6.28 and 2.6.29 releases contain an amazing amount of new functionality, such as a cutting-edge enterprise storage protocol, two new file systems, WiMAX broadband networking support, and storage integrity checking. Discover why it’s time to upgrade.

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.

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.

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.

Sem dúvida umas das minhas sérias preferidas sobre podcast é o developerWorks podcasts. Embora não seja só sobre Java como o Java Posse, no developerWorks podcast sempre encontro assuntos interessantes.
Eu já havia comentado sobre o developerWorks podcast, em dois artigos anteriores meu, o Grady Booch no Software Engineering Radio e Desenvolvimento ágil com Scott Ambler.
Ao escutar o ultimo podcast sobre o New teaching resources for BPM, Enterprise Computing, and Rational, onde Kevin Faughnan, Diretor do IBM Academic Initiative, e Dan Griffin, Program Manager for WebSphere and SOA participation dentro do Academic Initiative, falam sobre o novo programa de ensino e como estudantes e professores a usar tecnologias IBM.
Através de um comentário no New teaching resources for BPM, Enterprise Computing, and Rational, eu cheguei a este artigo Computer Science Enrollments: The Real News, um artigo que discute o interesse de estudantes em SCE (computer science & engineering), ciência da computação e engenharia da computação.
Cheguei a este artigo Why Choose CSE?, que possui uma coleções de videos da Universidade Washigton, para mostrar o que alunos de ciência da computação e engenharia da computação vão trabalhar depois da graduação.
Para fechar passei na página SkillPROOF, que procura fazer uma pesquisa sobre skill e jobs em demanda nos EUA.
Realmente esse links valem ouro.

Launchy is the most efficient way to open files, folders, websites, and programs on your computer. Nobody likes to hunt through the start menu to find an application, just to find that the application is hidden under some obscure folder named after a company you have never heard of! Instead, Launchy is a smart search program which tries to guess which program or file you are looking for and will launch it when you hit the enter key. It is only visible when you hit the alt+space (windows) or control+space (Linux) key combination; otherwise it hides in the background. Once you have used it for a few days, it becomes an indispensable utility for your computer. And it’s free!
I had installed Launchy version 1.03 in my windows xp desktop (a long time ago), but it is an old version. Launchy version 2.1.1 is available to download for Windows and for linux now. That’s great !
I really can not to survive without Launchy any more.
I will post here further about what I’m thinking about Launchy for Linux.
