[RELEASE] JogAmp 2.1.4 & JiGong at FOSDEM 2014

xerxes // Feb 1, 2014 2:30:16 PM

The JogAmp community held a Ji Gong freedom talk that reminded people to exercise the 4 freedoms granted by the free software licenses in front of the free java developer room audience. The talk also proposed and showcased technical enhancements for High Availability JVM Technology on All Platforms.
Slides from the Ji Gong talk can be obtained at: https://jogamp.org/doc/fosdem2014/

During the same week JogAmp released version 2.1.4 of its high performance java opengl audio & media processing librarys.
This release includes some new highlights:
* Android OpenCL test apk's. This enable you to compile and test an OpenCL JOCL application on desktop and then deploy on Android without using any OpenCL SDK for the phone, the JOCL binding will locate and bind the OpenCL drivers at runtime.
* Enable use of custom mouse pointers and window icons using the NEWT window and input toolkit.
* Multi window support on the Raspberry Pi including mouse-pointer use directly from console!
Complete list of bugs resolved for this 2.1.4 release can be found at:

Version 3.1.8

William Bittle // Dec 23, 2013 3:31:24 PM

This release of dyn4j is a maintenance release to fix a bug in the Vector2.distance(double,double) method.  It also had a few methods added to the Body class to get BodyFixture(s) at a given world space point.  See the change detail in the release notes.

A new release of the Sandbox was published for this release due to changes in WebStart security and an API change by JOGL.




Version 3.1.7

William Bittle // Oct 12, 2013 6:05:03 PM

This release of dyn4j is a maintenance release to fix bugs in the Ellipse.contains, Ellipse.getHalfHeight and HalfEllipse.contains methods.  This release also had a bug fix in the Graphics2DRenderer class.  See the change detail in the release notes.

This release has one breaking change: the Ellipse.getPointClosestToPoint method has been removed.  This method was based on an incorrect assumption and was removed for the time being.

No new release of the Sandbox was published for this release.




Version 3.1.6

William Bittle // Oct 6, 2013 8:40:01 PM

This release of dyn4j is a maintenance release to fix a bug in the Segment.getSegmentIntersection method.  A new method, setSlackEnabled, was also added to the PulleyJoint class to support a rope like constraint.  See the changes in the release notes.

This release should not contain any breaking changes.

No new release of the Sandbox was published for this release.




Version 3.1.5

William Bittle // Sep 14, 2013 8:23:02 PM

This release of dyn4j includes a number of new features including 4 new primitive shapes and convex casting.  In addition, a number of new helper methods have been added to the Geometry class.  See all the changes in the release notes.

This release should not contain any breaking changes unless you were using anything in the org.dyn4j.collision.continuous package directly.

The output of the convex casting features may be tweaked in future releases.

No new release of the Sandbox was published for this release.




The #JogAmp #JiGong project will package @OpenJDK + #IcedTea-web to enable good deployment on mobile phone platforms.

Preface

========

OpenJDK and its chair decided not to go mobile?

Bug 698 was written due to the "Fear, uncertainty and doubt" (FUD)
strategy of Oracle of not giving express permission to use OpenJDK
in compliance w/ the 4 freedoms of software (FSF definition).

On the contrary, Oracle gives a patent grant for using OpenJDK for desktop only,
implying mobile use may be prohibited.

This implication is highly likely non-sense, especially in the light of
the latest Oracle vs Google case where Oracle was not able to
substantiate a patent infringement by Google's Dalvik VM.

However .. the current situation lacks of:
- OpenJDK builds for Windows, OSX, Android, ..
- IcedTea-Web builds for Windows, OSX, Android, ..

As Xerxes put it: The horse is bound to a chair and is not running ..

Project Name

============
Ji Gong <https://en.wikipedia.org/wiki/Ji_Gong>
"Unlike a traditional Buddhist monk, Daoji did not like following traditional monastic codes. Daoji had a penchant for openly eating meat and drinking wine; his robes were often tattered and dirty from travelling from place to place, and stumbling while intoxicated. However, Daoji was kind hearted and was always ready to lend a helping hand to ordinary people. He would often treat the sick and fight against injustice. The monks, bewildered and fed up with his behavior, expelled Daoji from the monastery. From then on, Daoji roamed the streets and helped people whenever he could."

Hence Daoji does people good while not necessarily conforming to certain arbitrary rules,
while maintaining sanity and being kind hearted.

The character is quite popular in the Asian culture.

Project Spirit

==============

This project shall match the kind direction of it's name giving character,
while also serving w/ JogAmp's goals of being a technology enabler.

Ji Gong shall enable the VM technology across platform and devices.

This project must not necessarily being maintained by the JogAmp community.
On the contrary .. we would prefer this effort to be done from the original authors,
i.e. OpenJDK and IcedTea-Web.

However, until the goals below and this spirit of a free solution is being picked
up, we may continue pushing it forward from here.

Note: Bug 698 sadly wasn't being replied to by neither Oracle nor the OpenJDK team.
Of course, no surprise here, since for Oracle it might be a conflict of interest
due to their 'goals' to market their ARM hotspot proprietary solution
and the OpenJDK team consist mainly of Oracle and RedHat members.
The latter focuses on server solutions and is highly cooperating w/ Oracle.

Project Goal

============

- Availability of the GPLv2 based OpenJDK runtime environment (JRT/JVM)
- Desktop (Linux, Windows, OSX, ..)
- Mobile (Android, other phones and tablet OS [maybe even iOS])
- VM CPU support:
- Intel/AMD 32bit and 64bit
- ARM based CPUs [Hotspot client/server n/a at time of writing. May need to use JamVM or AvianVM, ..]

- Optional AWT/Swing/etc - maybe added at a later time

- Web Plugin based on IcedTea-Web (JWeb)
- Capable to run w/o AWT using a pluggable windowing subsystem implementation
- Optional AWT/Swing/etc - maybe added at a later time
