Using Your Built-In iSight With Parallels (and VMWare)

| Comments

It is probably an old tipe, but I have just configured my Windows XP Parallels VMs to use my MacBook buit-in iSight Web Cam using the driver that you can find here: - Download iSight Driver for XP

The site states that it does not work with Parallels, but I am using the release Build 3170 RC3 and I do not have any issue.

  1. Start your VM
  2. Download the Driver & Unip zip

  3. Grab the Built-In iSight using the Devices > USB menu

  4. Point the Windows Devices Manager Installer to the location of the Unzipped folder

  5. and you are done…

Online Public Libraries: Google Books and Now.. Europeana

| Comments

I am sure that you know about Google Books: http://books.google.com/

Even if I truly believe that Google wants the good by publishing all this information for free - We all remember the sentence: “Don’t be evil” that is part of the Google code of Conduct-. I think it is not a good idea to have only one service that provide access to the “world culture”… Competition is always good for consumer…

The French National Library (BNF) and some other public libraries (Hungarian, Portugal) have created a new site to offer a similar service in beta: http://www.europeana.eu. It is true that currently the list of books is really small compare to Google but I am inviting you to use both of then.

| Comments

During The Server Side Symposium in Vegas, Thomas Kurian announced that Oracle is acquiring Tangosol, during the keynote, Cameron Purdy (Tangosol’s CEO) has demonstrated how cool Coherence can be, and they have presented how it could be used in the context of XTP (Extreme Transaction Processing).

Soon more to come about this in the different technical side and blog of the Oracle’s community.

Grails vs Rails Performance Benchmark

| Comments

Graeme, the Grails Project Lead has published a very interesting benchmark of Grails versus Rails applications, that is available on the Grails wiki:

  • Grails vs Rails Performance BenchmarkingI let you read and comment on the Wiki the results… Grails development team is open to comment and improvement of the bench to capture as much information as possible.

It is also important to note that performances, productivity are very important when choosing a development environment; but something that is also key for enterprises, is the fact that Grails/Groovy “are” Java/J2EE based. This means that a Grails application is packaged, deployed, administered and monitored like any applications that already exist in the information system on J2EE application servers.

Using Groovy Within Oracle Data Integrator

| Comments

As you may remember, Oracle acquired few months back a data integration solution from Sunopsis, and has integrated it in our product under the name “Oracle Data Integrator” (ODI).

One of the first thing that I look when we got this product was the support for Scripting technologies, since it makes lot of sense to have such support in any ETL. And yes ODI has support for Jython (thought BSF). So when the dev team joined Oracle, I’ve asked the following question “did you try to use Groovy?”… I personnaly did not take the time to test, but one of the developer did and document it in his blog: “Using Groovy and ODI” from Thierry. When I get a chance I will provide a more complete sample of using Groovy in Oracle Data Integrator.

JavaEE 5 Features of OracleAS 10gR3

| Comments

OracleAS 10g R3 (10.1.3.x) is a certified J2EE 1.4 container, but OracleAS provides already support to some of the features of the Java Enterprise Edition 5: JavaEE 5. One of the key driver of the new EE version was simplification of the development and deployment applications. Here is the list of the JavaEE 5 features that are supported in OracleAS 10gR3 that will simplify the development of applications (in comparison to a standard J2EE 1.x development):

  • Java Persistence API (JPA) and EJB 3.0 (documention)

  • Support of shared library at the EAR level (<library-directory> / applib). (documentation). This comes in addition to the OracleAS 10gR3 classloader framework that allows administrators to create, and version shared libraries that can be used into applications by referencing them in the deployment plan.

  • Annotations Based Web Services (JSR181) that could be used for Java classes and EJB3 Session Beans (documentation)

  • Referencing resources using annotations in the Web container: @EJB, @Resource, @Resources, @PostConstruct, @PreDestroy, @PersistenceUnit, @PersistenceContext, @WebServiceRef, @DeclaresRoles, @RunAs (documentation) Hope that this small summary will give you the opportunity to test some of the features of OracleAS 10g.
