Pessoal,
Fiz uma apresentação no #10 Meetup Startup Sorocaba, cujo o tema foi 5 Dicas para economizar no desenvolvimento do seu aplicativo. A ideia da apresentação é dar 5 dicas para pessoas e empresas fazerem antes de começar a criar um aplicativo.
São dicas simples que qualquer empreendedor pode fazer, e vai ajudar a economizar tempo e dinheiro na criação do aplicativo.

Existem várias histórias de empreendedores de sucesso, mas temos que exaltar a iniciativa de alguns deles.
1)
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.
Tá na hora de abrir sua própria empresa da Vedovelli
2)
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.
Tá na hora de abrir sua própria empresa da FlexDev.
3)
É engraçado quando outras empresas nos ligam para saber sobre nossos cursos on-line ou sobre o Treina TOM. Todos acham que estamos em um grande centro, em plena avenida paulista e todos vestidos de ternos e gravatas, o ambiente cinza que muitas empresas que surgiram nos últimos 5 anos citam

I found that useful presentation on slideshare. It’s very interesting.
Take a look on Finding & Analyzing Influence (Gregor Hochmuth) – Web 2.0 Expo San Francisco.
Kleber Rodrigo de Carvalho
While Web 2.0 has been a huge hit with consumers, some businesses have been much slower to embrace it. Many companies, however, are now realizing the great potential of Web 2.0 and how Web 2.0 services such as YouTube, Twitter, and SlideShare can provide value to their organizations. See how businesses can exploit the power of Web 2.0 services while simultaneously improving workplace relationships. Empower your employees to share information that helps generate sales leads, aids in recruitment, and assists in strengthening your company’s brand, image, and corporate identity. Explore business-oriented Web 2.0 tools such as LinkedIn and CrunchBase and the Web services and APIs that many of these tools offer, allowing their benefits to be incorporated into other applications.

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).
Cloud computing 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.
If you want additional information about grid computing and cloud computing I advise you read these references below:

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 Availability project.
Redbook – z/VM and Linux on IBM System z The Virtualization Cookbook for SLES 10 SP2 – 2008
This IBM Redbooks publication describes how to roll your own Linux virtual servers on IBM System z hardware under z/VM. This edition applies to Version 5, Release 4, Modification 0 of z/VM (product number 5741-A05) and Novell SUSE Linux Enterprise Server (SLES) Version 10, Service Pack 2 (SP2).
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.
Redpaper – A Shared WebSphere Application Server Installation for Linux on zSeries – 2005
This IBM Redpaper describes a process to enable sharing one WebSphere Application Server installation among many Linux guests running under z/VM.
Redbook – Linux on IBM eServer zSeries and S/390: Best Security Practices – 2004
This IBM Redbook discusses best security practices for running Linux as a z/VM guest on IBM eServer zSeries and S/390 machines. This publication is intended for system administrators and IT architects responsible for deploying secure Linux servers running under z/VM. We consider both z/VM and Linux security topics.
Redbook – DB2 for Linux on iSeries: Implementation Guide – 2004
This IBM Redbook discusses DB2 UDB for Linux on iSeries. We provide the installation and configuration steps for DB2 UDB for Linux on iSeries. We also present connectivity scenarios between OS/400 resources and Linux resources.
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.
This tip details how to configure gcc on Linux for IBM eServer zSeries to act as a cross-compiler.
Redpapaper – Linux on IBM eServer zSeries and S/390: z/VM Configuration for WebSphere Deployments – 2003
In this Redpaper, we introduce a method to determine an efficient infrastructure for WebSphere deployment on Linux for zSeries. The infrastructure consists of LPARs running multiple Linux guests under VM. Each Linux guest runs WebSphere, which in turn runs Web applications. In this paper, we describe steps to configure z/VM Linux guests intended to run WebSphere applications. Specifically, we outline a method to calculate the memory required to deploy WebSphere applications, and describe how that memory should be allocated to the LPAR, z/VM, and Linux guests.
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.
Technote – Linux on IBM eServer zSeries: Configuring gcc as a cross-compiler – 2002
This tip details how to configure gcc on Linux for IBM eServer zSeries to act as a cross-compiler.

Hoje recebi um e-mail do meu primo Adriano. O e-mail é sobre uma entrevista de uma hora, na CNBC, com Warren Buffet, um dos homens mais ricos do mundo, que recentemente fez uma doação de 31 bilhões de dólares para a caridade.
Estou procurando a entrevista dele na integra em inglês, ainda não encontrei, mas os conselhos dele é sensacional. Veja os conselhos deles neste artigo que encontrei na net.
Achei um vídeo no youtube, que é a entrevista de uma hora com Warren Buffett, Bill e Melinda Gates sobre suas parcerias filantrópicas.
Também achei um artigo sobre Warren Buffet confirmando os 7 segredos para ter uma vida simples e feliz.
Na mesma linha de artigos encontrei um artigo do Warren Buffet e suas 10 dicas para ficar rico.
É incrível, ver o Warren Buffet, um bilionário que vive um vida simples e feliz, um exemplo para todos nós refletirmos sobre a vida.
