Java technology, IBM style: A new era in Java technology

The eagerly awaited final release of Java™ SE 7 is expected to include enhancements to all the major aspects of the language and the virtual machine. Both Oracle and IBM have released Early Access downloads of their respective implementations for review and feedback. In this article, Chris Bailey, architect of the Java service strategy at the IBM Java Technology Center, introduces some of the changes in store, from both the Oracle specification and the value-add that IBM provides.

Larry Ellison, da Oracle, declara guerra contra IBM e SAP

Acabei de ler essa reportagem Larry Ellison, da Oracle, declara guerra contra IBM e SAP, e decidi postar alguns pontos interessantes aqui.

Recomendo a leitura completa no artigo original.

o CEO da Oracle, Larry Ellison, ousadamente, declarou guerra contra as duas empresas atualmente líderes nos mercados-chave: a IBM, em servidores avançados, e a SAP, em aplicativos corporativos

Ellison compôs seu ataque à SAP com base no que disse sobre as três falhas-chave na estratégia da empresa: 1) tecnologia antiga e pouco competitiva da SAP; 2) ausência de aplicativos específicos para indústria; 3) tentativa desfocada de recuperar crescimento ao tentar vender software de ERP para pequenas e médias empresas.

Em aplicativos, a SAP é a líder. Mas a tecnologia que eles usam para esses aplicativos é uma tecnologia proprietária – uma linguagem de programação alemã chamada ABAP. É uma tecnologia de 25 anos que ainda é o centro de sua arquitetura e estratégia para aplicativos futuros, essa ABAP”, disse Ellison. “O centro da nossa estratégia, pensando no futuro, é Java e uma moderna arquitetura orientada a serviço.

“Me perdoem por falar tanto, mas, neste momento, a estratégia deles é tentar vender ERP para seus clientes com menos de 100 funcionários – essa é a nova estratégia deles, Business ByDesign, que, acredito, esteja atrasada uns três anos – e, caso seja bem-sucedida, não dá pra ganhar muito vendendo para empresas com menos de 100 funcionários”, disse.

GlassFish after Oracle acquisition

I have heard a lot of people worry about the future of Java, MySQL, Netbeans and GlassFish after that Oracle acquired Sun.

Today I read Adam Bien’s Weblog :

…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 enthusiast

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 think Oracle plans the same to GlassFish. The same that IBM does about Geronimo or WebSphere Application Server Community Edition (based on Geronimo).

The same that Red Hat does about its Red Hat Enterprise Linux and Fedora as well as SUSE pair does on SUSE Linux Enterprise and openSUSE.

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)

Entrevisa com Cezar Taurion

O blog do Academic Initiative IBM entrevistou o Cezar Taurin.
Veja a entrevista completa aqui.

Resumi e comentei as partes da entrevista que mais gostei.

> “Boi lerdo só bebe agua suja”…Veja o lado profissional. Se voce se mantiver na multidão e não se destacar, vai beber muita agua suja. Seja inovador, busque criar coisas novas.

Adorei essa máxima de parachoque de caminhão.

> blog: Na sua opinião, o que falta nos alunos IT?
> Cezar: Empreendedorismo…

Não só em alunos, com em profissionais também.

> blog: Sobre linguagens de programação, qual (is) tendência(s) para os próximos anos?
> Cezar: Como falei, escrevi programas em Cobol e Assembler. Recentemente me aventurei em Java, PHP e Python…brincadeiras e nada sério. Mas acredito que ao lado da Java, veremos as linguagens dinâmicas, voltadas à web, se disseminarem mais e mais. Estas linguages são PHP, Python, Perl e Ruby.
> blog: E o Java, ainda continua sendo um bom investimento para quem deseja aprender a tecnologia e entrar no mercado de trabalho?
>Cezar: Sim e vai continuar ppelas proximas geracoes. Como o Cobol…seu netinho vai programar em Java…

Concordo com o Cesar, Java vai continuar no mercado por muito tempo. Sobre as outras linguagens dinâmicas que estão surgindo eu aposto em PHP, Ruby, Python (nessa ordem de importância).

My blog highlighted in developerWorks

My blog is highlighted in developerWorks Java main page.

Since developerWorks implemented the social network called mydeveloperWorks (basead on Lotus Connection solution) I have participated in this social media. If you are in IT area, I really advise you to create you profile and get connected. MyDeveloperWorks is a fun way to keep updated and to learn which are the hot tech topics.

Automatic migration of Cobol to maintainable Java

I was searching about Java and mainframe and I found out NACA.

NACA was about replacing an IBM mainframe under MVS/OS390 (zOS) with Intel servers on Linux. The project started in January 2003 and successfully ended on june 30, 2007. It was on purpose implemented in a 100% iso-functional way, i.e. without any functional / applicational improvement brought during the process of trans-coding itself and by the transcoding engine. 4 millions lines of COBOL were 100% automatically trans-coded toward their Java equivalent.

The savings in cash-outs amounted to a total of 3 millions euros, 85% of the initial yearly level.

Publicitas now release its homegrown tools for this transcoding in open source

For more information on the NACA project (objectives, achievements, etc…) , check this page on their blog.

For more information about the tools that have been open sourced, check this page.
