I think one topic that came up in the trial was that the reason Google went
ahead with Harmony instead of upstream Java for Android was that the GPLed
release of Java came too late in the game to take into account. (Java was
released under some Sun community license or a similar pretty-open non-public
license).
Now Sun both as well as Oracle state that fragmentation for Java is a bad
thing.
The current state of affairs, which Oracle has not expressed interest in
reversing, is a GPLed Java if I am not mistaken.
So if there is damage, it is self-inflicted. And it has been caused by not
timely releasing Java under the GPL, but rather under a non-public license
reserving special status for Sun as the copyright holder.
So the message that Oracle is giving that Sun/Oracle have suffered billions of
losses due to not releasing Java under the GPL earlier than they did. They are
trying to reclaim those losses from Google, but are only getting a fraction from
that venue if at all the way things look.
This sounds like a very strong message not to mess with semi-open licenses just
to keep your own legal department thinking that they are useful. The
marketplace will not honor those efforts. Don't procrastinate with going GPL.[ Reply to This | Parent | # ]

I hadn't seen this BBC
video
from early February this year. It shows a chimp using a touch
screen
to play numbers games in which he displays superhuman
mathematical skill and
dexterity. Fascinating! [ Reply to This | Parent | # ]

I whipped up a program (in Java, of course) to look through the Java API
Specification (the Javadoc pages) and find out which classes and packages are
required by being mentioned in declaration and inheritance, starting with an
assumed base set of required classes and iterating to find the transitive
closure of dependencies.
In (almost) plain English, the program starts with an initial set of packages
and/or classes that are assumed to be required, then looks up the Javadoc page
for each class, finding the classes it inherits from, the class of each field,
and the return types and argument types of each method. Those classes are added
to the list, then the process repeats until no new classes are found.
By using the API Spec pages, private members and deprecated references to the
sun.* packages are ignored, which is just right for this purpose.
Here are the results I got for Java 1.5.0. The results are similar for Java
1.4.2, but somewhat fewer packages and classes.
The smaller test is starting with the following classes as ones that are
specifically required by the Java Language Reference, all in the java.lang
package: ClassLoader, Object, Class, Byte, Char, Integer, Long, Float, Double,
String, Throwable, Error, Exception, Thread
If anyone can point to other required classes that I missed that don't appear in
the following list of classes that these refer to, let me know and I'll add them
and run the program again.
This test shows the very minimal set of packages and classes that must be
implemented just to make sense of the Java Language Reference, not even counting
what might be needed to write useful programs.
The results starting with those in Java 1.5.0 are:
Final set contains 9 packages:
/java/io
/java/lang
/java/lang/annotation
/java/lang/reflect
/java/net
/java/nio

many packages and classes it started with, but not listing the hundreds of
classes by name):

MS observes that MacOS is not immune from malware
and they will help to keep
it that way.
An interesting case of Mac OSX malware

Lisp is one of the oldest languages, created at MIT in 1958. It, through
its
many dialects, is still widely used. In the 60s, 70s, and 80s, it was
considered a good language for researching AI (Artificial Intelligence) and
there were a few successful commercial companies selling their dialects
and
libraries,
programs, and fulfilling government research contracts. In the 80s,
though,
AI was declared a dead end and many of the companies folded, in
what
was known as AI Winter. Before it did, though, DARPA,
expressed irritation at
the fracturing of the language. In deference to a
major customer who said fix
it or else, an effort was made to unify the
language into something
which
became Common LISP. Kent Pitman, who was involved in that effort,
gave a
talk
in 2008 on his recollections and posted these to his
page.
While there is perhaps some illumination regarding language
design and process, the most interesting part of the story for Groklaw
readers
following Phase I of Oracle v. Google may be what Pitman said
when ANSI asked
him to sign over the copyright to the documentation he
wrote. This is found in
Section 6.2. I also have to thank
lambda-the-ultimate.org and Manuel J.
Simoni for pointing me to Pitman's
post. [ Reply to This | Parent | # ]

Supposedly the biggest full moon of 2012, it came up minutes ago over
Pensacola Beach (Florida). I know the moon always seems extra big on
the horizon, but its speed in rising tonight is also impressive.
