dwarfking (95773) writes "For those that don't recall, in the late 70's and early 80's, there was a portable operating system referred to as P-System, which was really an interpreter for a software based machine. The primary language for this system was UCSD-Pascal and the compiler emitted P-Code instructions, but other languages used P-Code as well, such as Visual Basic.
When new hardware architectures were created, one of the first pieces of software ported was the P-Code interpreter. Then a compiler that ran on the P-Code was modified to emit machine code for the new hardware. The P-Code based compiler would then be compiled to native, thus boot strapping a compiler onto new architecture.
Then the resulting code can (theoretically) run everywhere the JVM and supporting JRE classes have been ported.
Researchers are using Java and the JVM to test out new theories in language development and Sun is working on Da Vinci to make porting other languages even easier.
One difference with the JVM and the old P-Code/P-System tools is that users of the JVM assume the presence of the JDK and nearly all of these languages that target the JVM expose Java objects.
So the questions be asked are
Is the JVM becoming the default target hardware platform?
Is that a good thing or a bad thing? Why or why not?
What types of enhancements does the software machine provided by the JVM need?
Will future developers be conditioned to assume that their language of choice always provides the volume of components the JDK offers just like many of them today can only work if there is a graphical IDE avaliable?
Now that Sun has open sourced it, how can we make it better?
dwarfking (95773) writes "There have been some pretty lively debates recently on Slashdot about whether Java is dying or not. This article discusses a survey that shows Java use for SOA going up while.NET use is dropping.
What was interesting though is the comment
"There's currently a lot of activity in the open source world, and particularly in the Eclipse communities, around SOA" says John Andrews, chief executive officer at Evans Data. "Most of the major players in that space are introducing new solutions aimed at SOA, and they are almost invariably Java-based. Open source SOA looks poised to become a real force in the industry and consequently a serious contender to.NET."
So is it the Eclipse tool which is able to compete with Visual Studio, or simply because Java is not vendor locked that is driving this?" Link to Original Source top
dwarfking (95773) writes "The subject line is a bit tongue-in-cheek, but the article about a lawsuite of the IP of a salad recipe is either funny or scary, depending on the outcome.
From the article:
But the legal action, one of the first in which a restaurant owner has gone to court over intellectual property, has opened up a veritable can of lobster tails over when culinary influences stray into imitation.
What seems to have upset Ms Charles in particular is Ed's Caesar, a $7 (£3.50) salad that she alleges in the legal action was taken from her own recipe. But Ms Charles acquired the recipe from her mother, who, in turn, wheedled it out of a chef in Los Angeles.
dwarfking (95773) writes "Over the last several months I have noticed that more and more often when I am searching for information on the web, I find myself starting at Wikipedia instead of Google. It used to be that the first hit on many of my Google searches linked to Wikipedia articles, so I started going there first.
I've found that except for searching for current events, by starting with Wikipedia I get a good explanation of the topic of interest and the pages generally have links to other good resources that are right on topic. No need to scroll through dozens of hits.
So my question to the slashdot community is, are others of you seeing similar shifts in your search usage and if so, do any of you think this could become a trend for the larger community? If so, then what could that potentially mean for Google?" top
dwarfking (95773) writes "Ok, maybe I'm a little dense here, but isn't this plan more of an impact to the content provider than to the search engines. From the article:
In one example of how ACAP would work, a newspaper publisher could grant search engines permission to index its site, but specify that only select ones display articles for a limited time after paying a royalty.
So, ok, a search engine company decides it doesn't want to pay royalties and therefor doesn't index the provider's site. Now won't the provider actually lose readers since their articles won't be locatable by search anymore?"
