As an extension to the flash memory speed tests,

tried inserting records into derby:
CREATE TABLE number (oid INT, PRIMARY KEY(oid));
INSERT INTO number(oid) values(?);

oid=1...n
database size :
1kRecs : 760kB
10kRecs : 2.4MB
100kRecs : 9.4MB
1000kRecs: 57.6MB

create database and table takes about 2 seconds.
important when number of records is small
commit size is main factor.

Observe Moiré (flat because close, translucid)
Loose outer Dome ( C,S radius -> ∞; D ->0) (Loose outer, instead of inner to preserve rotation)
Discreet blend from F=45(30),..,3(6), and back to 24. (to see structure)

Using Dome to generate Geodesic domes for POV-Ray

./dome_4_80/dome -f15 -sb dome15.pov
mv dome.inc dome15.inc
dome15.inc:#declare DomePoints15=
dome15.inc:#declare DomeEdges15=


./dome_4_80/dome -f18 -sb dome18.pov
mv dome.inc dome18.inc
dome18.inc:#declare DomePoints18=
dome18.inc:#declare DomeEdges18=

combine dome15.pov and dome18.pov
into dome-both.pov (add missing semi-colons)
#include"dome15.inc"
#include"dome18.inc"
...
#declare Dome15=
union{
object {DomeEdges15 no_shadow texture{EdgeTexture}}
object {DomePoints15 no_shadow texture{PointTexture}}
}

#declare Dome18=
union{
object {DomeEdges18 no_shadow texture{EdgeTexture}}
object {DomePoints18 no_shadow texture{PointTexture18}}
}

object{Dome15 rotate <22,> scale <1.1,1.1,1.1> }
object{Dome18 rotate <0,> }

72 degrees should do it for bucky balls

Kn.n = set frame clock to n.n
KFIn = set initial frame number to n
KFFn = set final frame number to n
KIn.n = set initial clock value to n.n
KFn.n = set final clock value to n.n
SFn|0.n = start subset at frame n | start at n percent in sequence
EFn|0.n = end subset at frame n | end at n percent in sequence
KC = calculate clock value for cyclic animation

Example of JfreeChart and WebStart (JNLP) integration.
See also Extension I.
JFreeChart Extension II

For Webapp use:
Cewolf

To move progressively to appfuse structure:
+ create simple DAO for one entity by hand
- move to generated hbm files (xdoclet integration)
- move to autowired factories with spring

-create client/server source trees
-implment simple web service

-JNLP delivery for client
-client side Thread Worker

For a in-process database to be persisted, must call
checkpoint, or shutdown [compact]

hibernate.connection.url jdbc:hsqldb:file:test

To acces Hsql database:
java hsqldb.jar --rcfile sqltool.rc test
----- sqltool.rc ----
# A personal Filebased Database
urlid test
url jdbc:hsqldb:file:test
username sa
password
--------------------

-Move Media info to POJO.
-Persist POJO in local Datasource (Hibernate of JDBC DAO)
and integrate build (new lib/common/client)
-Thread for GaloClient
-First JNLP based on Progress2
-Expose Webservice with Axis
-Catchup un unit tests

Traverse Directory tree advising IFileHandler
of each Directory and File that is reached:
org.galo.filesystem:

public interface IFileHandler {
    public void handle(File f);
}
public class BaseWalker {
    public BaseWalker(IFileHandler directoryHandler,
                      IFileHandler fileHandler) ;
}

There are static shortcuts:

int DirectoryWalker.count(File baseDir);
List DirectoryWalker.list(File baseDir);
int FileWalker.count(File baseDir);
List DirectoryWalker.list(File baseDir);

public interface IFileHandler {
    public void handle(File f);
