Oracle Opensource NoSQL Hadoop R

Posted on 08/10/2011 by matteo

Oracle’s comprehensive big data strategy includes NoSQL, Hadoop, and R analytics

“Oracle’s planned distribution of the open-source R statistical environment will be adapted for use on large-scale data within the Oracle database, rather than on desktops and laptops where analysts typically use the software. Oracle R Enterprise will run existing R applications and it will use the R client directly against data stored in Oracle Database 11g. This will vastly increase scalability, performance, and security, according to Oracle, along with the promise of software support. Oracle will ship the open-source distribution along with Linux. Separate R packages with database-specific extensions for Oracle 11g will be bundled with that database”. Taken from an Informationweek article.

Aboliamo le province, più potere alle regioni!

Posted on 10/07/2011 by matteo

Riduciamo i costi della politica italiana abolendo le province e dando alle regioni le competenze che oggi spettano alle province!

Di cosa si occupano le province oltre che manutenere le strade provinciali?

Moodle 2.1 released!

Posted on 07/07/2011 by matteo

“Moodle is a software package for producing Internet-based courses and web sites. It is a global development project designed to support a social constructionist framework of education.

Moodle is provided freely as Open Source software (under the GNU Public License).” [from About_Moodle]

“You can read more on the Moodle 2.1 release notes, but the major new features are:

  • A whole new question engine (used by quizzes, for example), which makes questions more robust and will enable developers to create all kinds of interesting question types in the future. Some interesting new features like Certainty-Based Marking have also been added. Huge thanks are due to Tim Hunt and Open University for all their work on this.
  • Restoring of Moodle 1.9 backups is now possible! Thanks to Moodlerooms for their help in some of the key parts of the core work and to the HQ team for the rest. This was a very complex thing to build due to the many changes between 1.9 and 2.x. Note that only course content in core modules is restored: if you use other activity modules then you need to ask (or help) the developers of those modules to add the new module restore code (thanks to the design this is not a huge task to implement).
  • Moodle 2.1 now directly supports mobile apps for some functions. The new Moodle app for iPhone (by Moodle HQ) will be released soon (followed by an Android version later) and these require the secure web services of Moodle 2.1 or later. In addition, there is direct support for mobile-specific Moodle Themes and automatic detection of mobile browsers.
  • Moodle 2.0 Release notes

 

There are many other smaller improvements too, but one of the ones I really like is the new and improved configuration interface for blocks. You should find it a lot easier to understand than the one in Moodle 2.0.” [from Moodle News]
