Posted by abhiitechie on May 18, 2009

As it is very difficult for everyone  to make the trip to San Francisco to attend JavaOne. That’s why special arrangements has been made to bring JavaOne to the Open Source University Meetup (OSUM) Community.  OSUM has scheduled a series of webinars which are previews of hands-on labs that will be conducted at JavaOne.

Check the OSUM events calendar for the complete schedule and RSVP today.

OpenSolaris 2008.11 Mini-Book

Posted by abhiitechie on May 17, 2009

The Getting Started with OpenSOlaris 2008.11 mini-books were recentlyOpenSolaris released. They are available in English, Brazilian Portuguese, Spanish, Italian, German, Traditional Chinese, Simplified Chinese, Korean and Japanese.

You might notice that there is a difference between the content of these books. They are composed by three different documents, and only the ones in English, Simplified Chinese and Japanese have them all. All other languages have only one document.

The books have a pretty basic approach, so they are aimed at people who doesn’t have much experience with the OS. This makes them perfect to be indicated during basic courses and presentations.

It seems that the 2008.11 version of these mini-books will be available only in the digital format.

Open Source University Meetup (OSUM) now more open

Posted by abhiitechie on April 27, 2009

I guess everybody involved in SUN activities has awareness about OSUM. OSUM was in the past very closed socical network. One needs to be registred in to see what is inside. After long time it has changed to the better way. OSUM is going to be more open to the public now. It means more information and more reasons to be registred in. I guess one of the main principes of any open community is to be open. OSUM is now going to reach this goal.  Have a look at public profile of the groups. Anyway changes are comming .

Open Source car by EDAG

Posted by abhiitechie on April 27, 2009

We’re pretty comfortable with the idea of open source software running on computers and mobile phone — heck, even guitars — but cars?
That one we’re still warming up to, but this concept vehicle from EDAG definitely helps. As its name implies, the Light Car – Open Source lets developers modify and / or improve upon the auto’s technologies — or at least put a SNES emulator on the back. The lithium ion-powered bubble car also sports an OLED-infused exterior for lights and signals that are supposedly useful both to the driver and other nearby motorists, but in actuality we suspect it’d just scare anyone tailing behind. No information on the interior, but we imagine a decked out dashboard and some futuristic chairs. It’s currently being shown off at the Geneva Motor Show.

How to open a .war (web archive) or .jar (java archive) files

Posted by abhiitechie on April 27, 2009

With Java we generate .JAR files to bundle a set of resources. For J2EE web applications, we generate .WAR (Web Archive) files for deployments. Both of these are ways of archiving a set of files.

Both these .jar or .war archives are in zip format. So there are plenty of ways to open those files to read the content. One way would be to use any tool that you use to open/extract a .zip file. Next will be to use the Jar command itself.

JAR Command

JAR (command) utility in Java can be used to open/extract these files as follows. Run following command from the folder where you need the content to be extracted by providing the path to the archive.

jar xf

options:

x – extract the files
f – file to extract

jar xf myWebApp.war
jar xf myProject.jar

The Sun won’t set at NIT Durgapur … I promise !

Posted by abhiitechie on April 25, 2009

As we all might have heard, Oracle has entered into an agreement to acquire Sun. While it is natural to have questions following an announcement of this magnitude, its also important to acknowledge that this is an
industry transforming event. The following excerpt from the Oracle Press Release helps to highlight this point.

“This is a fantastic day for Sun’s customers, developers, partners and employees across the globe, joining forces with the global leader in enterprise software to drive innovation and value across every aspect of
the technology marketplace,” said Jonathan Schwartz, Sun’s CEO, “From the Java platform touching nearly every business system on earth, powering billions of consumers on mobile handsets and consumer electronics, to the convergence of storage, networking and computing driven by the Solaris operating system and Sun’s SPARC and x64 systems.”

Coming back to the question of what will be the future of MySQL under Oracle. I think that as long as there is a demand for a product and such a vibrant community of users and developers behind it the product will never die.

Since it is all business as usual, we should not create a huge fuss about Oracle acquiring Sun and the future of Sun Campus Ambassadorship and the Sun Academic Initiative (SAI). I think we all should focus on our respective efforts to evangelize Free Softwares and continue conducting Talks , Workshops and related Technical sessions and continue building the Talk culture in our college which has just started some times back. We should try building the best open source community in NIT Durgapur with our Sun Club and the GNU/Linux Users’ Group.
