Do you still do a confusion between Intel core 2 duo vs Intel dual core ? We also have others king of processors:
- The Pentium Dual-Core brand refers to mainstream x86-architecture
microprocessors from Intel. They are based on either the 32-bit Yonah
or (with quite different microarchitectures) 64-bit Merom, Allendale,
and, more recently, with the launch of the model E5200, Wolfdale core,
targeted at mobile or desktop computers. In terms of features, price
and performance at a given clock frequency, Pentium Dual-Core
processors are positioned above Celeron but below Core and Core 2
microprocessors in Intel's product range. The Core 2 brand was
introduced on July 27, 2006, comprising the Solo (single-core), Duo
(dual-core), Quad (quad-core), and in 2007, the Extreme (dual- or
quad-core CPUs for enthusiasts) version. Intel Core 2 processors with
vPro technology (designed for businesses) include the dual-core and
- The Core brand refers to Intel's 32-bit mobile dual-core x86 CPUs
that derived from the Pentium M branded processors. The processor
family used a more advanced version of the Intel P6 microarchitecture.
It emerged in parallel with the NetBurst (Intel P68) microarchitecture
of the Pentium 4 brand, and was a precursor of the 64-bit Core
microarchitecture of Core 2 branded CPUs. The Core brand comprised two
branches: the Duo (dual-core) and Solo (Duo with one disabled core,
which replaced the Pentium M brand of single-core mobile processor).
Intel Core 2
- The Core 2 brand refers to a range of Intel's consumer 64-bit x86-64
single-, dual-, and quad-core CPUs based on the Intel Core
microarchitecture. The single- and dual-core models are single-die,
whereas the quad-core models comprise of two dies, each containing two
cores, packaged in a multi-chip module. The introduction of Core 2
relegated the Pentium brand to the mid-range market, and reunified
laptop and desktop CPU lines, which previously had been divided into
the Pentium 4, Pentium D, and Pentium M brand.
If you read these information (from Wikipedia) and still aren't understanding, I advised you read this article on binaryday.com.
The confusion between Intel core 2 duo and Intel dual core primarily
resulted from a pointless naming convention by Intel. 2 and dual may be
synonyms in English but that does not make Intel core 2 duo vs Intel dual core
any more similar. The similarity of names makes even many computer
geeks confused when asked to do a comparison of Intel core 2 duo and
Intel dual core.
Intel Dual Core is the first dual-core CPU from Intel. The Dual core
makes use of two cores on a single die i.e it has two chips in one
package. It solves the problem of overheating of Intel Pentium D without compromising on the performance.
Intel Core 2 Duo processors are the next gen processors from Intel.
It is developed with a new Architecture called Core. The new
architecture of Intel core2 duo makes it a lot better processor that
runs cool. Most importantly the Intel core2 duo is a super over clocker.
Service Oriented Architecture For Dummies, 2nd IBM Limited Edition.
Service Oriented Architecture (SOA) is the most important technology
initiative facing businesses today. SOA is game changing, and early SOA
successes make it clear that SOA is here to stay. This book introduces
you to the basics of SOA in context with the real life experiences of
seven companies. Seen through the varied business environments depicted
in each of the case studies, we hope you will recognize that SOA is
more than a bunch of new software products strung together to allow
technology companies to have something else to sell. SOA represents a
dramatic change in the relationship between business and IT. SOA makes
technology a true business enabler and empowers business and technology
Eu terminando minhas disciplinas no curso de MBA em Sistemas Corporativos de Alto Desempenho –
Mainframes e Servidores de Grande Porte na FIAP. O curso de MBA
(Master of Business Administration) que é o Mestrado em Administração de
Empresas é um grau acadêmico ao nível do mestrado destinado a
administradores e executivos na área de gestão de empresas. Difere do
MBA (Master of Business Administration), que traduzindo também significa
mestrado em administração de empresas. Apesar do MBA ter grau de
“mestrado” em diversos países, no Brasil ele é enquadrado como
“Especialização”, ou seja, uma “Pós-graduação Lato Sensu”. Quem o obtém,
portanto, não tem o título de Mestre reconhecido no Brasil.
Mesmo com essa diferença entre o MBA feito fora do Brasil e o MBA
feito no Brasil, o foco do curso é “business”, ou seja como o gestor de
TI pode usar a Arquitetura de Servidores de Alto Desempenho para
impulsionar o seu negócio. O nome do curso é MBA em Sistemas
Corporativos de Alto Desempenho – Mainframes e Servidores de Grande
Porte, mas gosto de falar Arquitetura de Servidores de Alto Desempenho
para resumir do que o curso trata. Também já vi traduções para este
curso como a Data Center and Enterprise Systems Management MBA
ou como eu mesmo já escrevi High Availability in Enterprise Systems.
O curso é desenvolvido para habilitar o profissional a avaliar – com
um enfoque abrangente – a atual infraestrutura tecnológica na qual atua
e propor melhorias em seus mais diferentes componentes, sejam de
hardware, de software, de comunicação de dados e redes e da
infraestrutura de TI em geral, segundo os melhores conceitos de gestão
empregados pelas maiores empresas do mercado. Na verdade no curso temos
várias disciplinas de arquitetura dos servidores tanto da perspectiva
de harware como de software nas 3 principais plataformas.
Servidores RISC, com sistemas operacionais UNIX e LINUX;
Servidores Intel / x86 / Windows based de alta performance, com
sistema operacional Windows/Server;
Servidores Mainframes IBM System Z, com sistemas operacionais Z/OS e
Através dessas 3 principais plataformas (RISC, x86 e Mainframe),
vemos também comunicação de dados e redes e da infraestrutura de TI em
geral nessas plataformas.
No site do curso de MBA, tem o conteúdo programático,
que se divide em uma carga horária total de 380 horas.
Esse curso me deu uma ótima visão sobre Servidores RISC, com sistemas
operacionais UNIX e LINUX, Servidores Intel / x86 / Windows based de
alta performance, com sistema operacional Windows/Server e Servidores
Mainframes IBM System Z, com sistemas operacionais Z/OS e LINUX, além
de abordar soluções de STORAGE armazenamento de alta capacidade nessa 3
plataformas também. Para quem saber mais sobre o conteúdo programático
do curso, pode acessar o site do curso ou a tradução que eu fiz do contéudo programático para o
Já estou usando conceitos aprendido durante o curso no meu dia a
dias, e tenho certeza que esse curso ajudou muito no meu crescimento
profissional. Fica ai ai dica para quem quer estudar um pouco sobre
Arquitetura de Servidores de Grande Porte.
Lately I've been studying mainframe architecture because I'm responsible for production operations of an application and since August/2008 it is running over zLinux architecture. I'm listing below some useful source about zlinux. It's in order by year.
Redbook - Achieving High Availability on Linux for System z with Linux-HA Release 2 - 2009
As Linux® on System z® becomes more prevalent and mainstream in the
industry, the need for it to deliver higher levels of availability is
also increasing. IBM® supports the Linux High Availability (HA) project
( see http://www.linux-ha.org/ ) which provides high availability
functions to the open source community. One component of the Linux HA
project is a program known as Heartbeat. Heartbeat runs on every known
Linux platform. Heartbeat is part of the framework of the Linux High
Redbook - Problem Determination for Linux on System z - 2008 This IBM Redbooks publication addresses some of the common problems that customers have experienced on the Linux® on System z™ platform. This book provides a problem determination methodology and tools to help the reader diagnose the problem in an easy-to-read self-help manual.
Redbook - z/VM and Linux Operations for z/OS System Programmers - 2008 This IBM Redbooks publication discusses z/VM and Linux operations from
the perspective of the z/OS programmer or system programmer. Although
other books have been written about many of these topics, this book
gives enough information about each topic to describe z/VM and Linux on
IBM System z operations to somebody who is new to both environments. This
book is intended for z/OS programmers and system programmers who are
transitioning to the z/VM and Linux on System z environments and who
want a translation guide for assistance. We base this book on our
experiences using System z10 Enterprise Edition, z/VM version 5.3 RSU
0701, and Novell SUSE Linux Enterprise Server (SLES) 10 on System z.
Redpaper - Sharing and maintaining Linux under z/VM - 2008
Large operating systems, such as z/OS , have, for several decades,
taken advantage of shared file structures. The benefits of a shared
file structure are reduced disk space, simplified maintenance, and
simplified systems management. This IBM Redpaper describes how to
create a Linux solution with shared file systems on IBM System z
hardware (the mainframe) running under z/VM. It also describes a
maintenance system where the same Linux image exists on a test,
maintenance and gold virtual servers.
Redbook - WebSphere for Linux on iSeries: Implementation Guide - 2004 This IBM Redbook is about WebSphere Application Server V5.0.2 for Linux on iSeries. It begins with a brief discussion of WebSphere Application Server V5.0.2, then provides details about product positioning on the OS/400 versus Linux for iSeries platforms, and about the features included in various packaging options.
Redbook - Linux on IBM eServer zSeries and S/390: Application Development - 2002
This IBM Redbook describes application development for Linux on the IBM
eServer zSeries platform. The target audience is application developers
writing primarily in C/C++ and Java.
The Linux development environment for zSeries is quite similar to the
development environment on other platforms running Linux since the
operating system services and development tools share a common code
base. We note differences and optimizations specific to the zSeries
platform where applicable.
When I think about grid computing I think about an application such as SETI@home.
Grid computing is the application of several computers to a single
problem at the same time, usually to a scientific or technical problem
that requires a great number of computer processing cycles or access to
large amounts of data. What distinguishes grid computing from
conventional cluster computing systems is that grids tend to be more
loosely coupled, heterogeneous, and geographically dispersed. Also,
while a computing grid may be dedicated to a specialized application,
it is often constructed with the aid of general-purpose grid software
libraries and middleware.
I don't know why I was mixing up grid computing with peer-to-peer.
A peer-to-peer (or P2P) computer network uses diverse connectivity
between participants in a network and the cumulative bandwidth of
network participants rather than conventional centralized resources
where a relatively low number of servers provide the core value to a
service or application. A pure P2P network does not have the notion of
clients or servers but only equal peer nodes that simultaneously
function as both "clients" and "servers" to the other nodes on the
network. This model of network arrangement differs from the client-server model where communication is usually to and from a central server. When I think about peer-to-peer network I keep in mind applications such as aMule for Linux, e-mule for Windows and Vuze (formerly Azureus).
is a style of computing in which dynamically scalable and often
virtualized resources are provided as a service over the Internet.
Users need not have knowledge of, expertise in, or control over the
technology infrastructure "in the cloud" that supports them.The concept
incorporates infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service
(SaaS) as well as other recent technology trends that have the common
theme of reliance on the Internet for satisfying the computing needs of
the users. Cloud computing services usually provide common business
applications online that are accessed from a web browser, while the
software and data are stored on the servers.
Cloud computing is often confused with grid computing
("a form of distributed computing whereby a 'super and virtual
computer' is composed of a cluster of networked, loosely-coupled
computers, acting in concert to perform very large tasks" ) , utility
computing (the "packaging of computing resources, such as computation
and storage, as a metered service similar to a traditional public
utility such as electricity" ) and autonomic computing ("computer systems
capable of self-management" ) . When I think about cloud computing, I keep in mind companies such as IBM, Amazon, Google, Microsoft or Yahoo which are some of the major cloud computing service providers.
...Oracle GlassFish Server is part of the Oracle Fusion
Middleware application grid portfolio and is ideally suited for
applications requiring lightweight infrastructure with the most
up-to-date implementation of enterprise Java, Java EE 6, and Java Web
services. Oracle GlassFish Server complements Oracle WebLogic Server,
which is designed to run the broader portfolio of Oracle Fusion
Middleware and large-scale enterprise applications..."Read the whole paper.
I admire Sun. They created those awesome products such as Java, Netbean, GlassFish, VirtualBox and son on, however I have to admit that Sun business model wasn't working.
If you still believe that Sun business model worked, answer me, why did shareholder approve to sale Sun to Oracle?
Do you sell your company or company share if it is still profit?
No, I don't. I just sell it if I have losses.
I'm not concerned about the future of Java, MySQL, Netbeans and
GlassFish, however I make sure that Oracle will change the business
model behind of these products.
I advise Oracle to keep up the open source communities that maintain
these products so beloved by developers and open source enthusiast;
however Oracle need to profit through these products. To keep an open
source product alive, they need to spend money.
I advise Oracle to keep up the open source communities
that maintain these products so beloved by developers and open source
How much does IBM spend to keep Geronimo community active? There are a couple of IBM employees working on this open source project.
How much did Sun spend to keep GlassFish or Netbeans community
active? There were a couple of Sun employees working on this open
source project too.
How much will Oracle spend to keep GlassFish or Nebeans community
push on? There are many Sun-Oracle employees working on this open
source project too.
In a successful manner open source projects such as Eclipse, Linux,
and so forth survive nowadays, because there are a lot of companies
investing money, time, and resources in these products. For instance, a
couple of IBM Rational products are based on Eclipse. How many
companies release hardware and software products based on Linux?
All those companies that are investing in open source products are
interested for some reason on these open source products, I can bet the
reason is these open source products are helping their business model.
Open source products are helping their business model.
I'm not worry about, since now Oracle GlassFish Server
is part of the Oracle Fusion Middleware application grid portfolio. As
Java developer and Architect I really support that Oracle and IBM offer
for purchase their application servers and spread their Java portfolio.
I really want that Oracle to keep up the open source communities
that maintain these products so beloved by developers and open source
enthusiast, and also improve them (products and communities)
Existem várias histórias de empreendedores de sucesso, mas temos que
exaltar a iniciativa de alguns deles.
Meu camarada José Carlos Fiel veio me perguntar: “- To
pensando em abrir minha empresa. Gostaria de saber de vc o que deve ser
evitado e com o que tomar cuidado”.Bem, como eu sou meio que macaco-véio
nesse lance de ter empresa (já tive 3), posso listar aqui o fiz de
errado, para seu entretenimento (caso vc não seja esperto) ou para que
vc se oriente (caso seja). Isso não é conselho, nem dica, nem nada
disso. São apenas pontos que me fizeram dar boas cabeçadas e que agora,
na terceira tentativa, estou procurando evitar.
Através de um convite feito pelo meu amigo @vedovelli
através do seu blog, obrigado pelo convite e parabéns pelo texto, vou
expor rapidamente alguns pontos de vista que desenvolvi nesses quase 2
anos de empresa.
