Submission + - JPA 2.0 - Java's Answer to LINQ.

An anonymous reader writes: Java is set to get a decent equivalent to Microsoft's LINQ via the Java Persistence API 2.0 (JPA). The spec is at the final draft stage. JPA 2.0 takes a very different approach to that taken by Microsoft exploiting the annotation code generator built in to Java as an alternative to adding method and type literals (commonly referred to as "DSL support") to the Java language itself. Whilst driven out of necessity the resulting API has greater type safety than would be obtainable via the language level changes without adding further complexity to the Java language itself. The technique has wider applications for programmers wishing to use their Java knowledge to explore Domain Specific Languages. InfoQ has a good summary of the approach.

Submission + - Pulsar Signals Could Be Used For Interstellar GPS (technologyreview.com)

KentuckyFC writes: "We're all familiar with GPS. It consists of a network of satellites that each broadcast a time signal. A receiver on Earth can then work out its position in three-dimensional space by comparing the arrival times of the signals from at least three satellites. That's handy but it only works on Earth. Now astronomers say that the millisecond signals from a network of pulsars could allow GPS-style navigation on a galactic scale. They propose using four pulsars that form a rough tetrahedron with the Solar System at its centre, and a co-ordinate system with its origin at 00:00 on 1 January 2001 at the focal point of the Interplanetary Scintillation Array, the radio telescope near Cambridge in the UK that first observed pulsars. The additional complexity of sending signals over these distances is that relativity has to be taken into account (which is why the origin is defined as a point in space-time rather than just space). The pulsar GPS system should allow users to determine their position in space-time anywhere in the galaxy to within a few nanoseconds, which corresponds to an accuracy of about a metre."

Submission + - Gumblar Virus Mutation Makes Google-Search Toxic (startupearth.com)

An anonymous reader writes: A massive number of popular websites are being infected with a virus which uses vulnerabilities in Adobe's PDF Reader and Flash Player to inject malware into otherwise trusted links, which infect visitors silently, and re-direct Google searches to malware sites.

Submission + - Inflammatory document posted - Police Corruption (cultureghost.org)

IndianaKim writes: I posted last week asking if I should host a highly inflammatory document that is incriminating toward a police department. I did not end up hosting the document and although I advised, as you all suggested, using wikileaks, they found a host on their own.

I will let their posts and their description provide you the rest of the information.

Submission + - Federal CIO Kundra says IT is path to transparency (nextgov.com)

GovTechGuy writes: Since his appointment in March as federal chief information officer, Vivek Kundra has had a full plate. Also the e-government administrator at the Office of Management and Budget, Kundra has taken on the formidable task of increasing the transparency of government data and oversight of information technology investments. In addition, he's faced personal scrutiny when the FBI launched an investigation into bribery charges at his former office with the District of Columbia government, where he was chief technology officer. Nextgov spoke with Kundra on Wednesday about the challenges of his new position and what he hopes to accomplish in this administration's era of open government. Edited excerpts from the interview follow.

Submission + - AGW 'skeptic' produces hard data; nobody notices

MyFirstNameIsPaul writes: "Anthony Watts, a meteorologist from Chico, California founded a volunteer project, surfacestations.org, in 2007 with the goal of surveying all of the 1221 United States Historical Climatology Network (USHCN) weather stations to see how well they meet the National Weather Service's (NWS) own siting requirements. These are the stations that report the official record of temperatures here in the U.S. The project uses a network of volunteers armed with basic tools such as cameras, tape measures, GPS units, and a printout of the project's instructions to report the results of the surveys to the project.

In May, the project completed its first report with 70% of the USHCN stations having been surveyed. This report found, among other things, that 89% of the stations fail to meet the NWS requirements. Of note is that they failed in such a way that the stations would likely indicate higher temperatures. The report also discusses the poor recording processes of many stations and how the data is 'adjusted' by the National Oceanic and Atmospheric Administration (NOAA) and NASA.

But most disappointing is the complete lack of coverage by virtually all media. This simple and provocative investigation into the data which is at the very heart of the entire AGW theory doesn't seem to register anywhere when, at the very least, it should warrant a demand for a solid rebuttal from the theory's proponents by the media. There are some out there who are warning of the new 'Climate-Industrial Complex', of which perhaps the media is a beneficiary."
Software

Submission + - What free IDE do you use? 2

postermmxvicom writes: "I program only occasionally and mostly for personal interest. I went to update my favorite free IDE yesterday when I noticed that DEVCPP has not been updated since 2005! It was like I lost a friend :( So, I went looking for other free IDE's and came across Code::Blocks and visual studio express. I work from a windows machine and use C++. I make mostly console apps, but have written a few windows apps and D3D or OpenGl apps.

I wanted to know what free IDE's you use and recommend. What do you like about them? What features do they lack? What about them irritate you (and what do you do to work around these annoyances)? For instance, when I used Visual C++ 6.0 in college, there was an error in getline that had to be fixed and devcpp's code indenting needed to be tweaked to suit my liking."

Comment Re:Copyright law? (Score 1) 203

If you actually read 12USC1201, you'd know that it is illegal to sell a VCR that does not respect the macrovision flag. In the exact same way, there are flags in RTMP media that control access to the underlying content. rtmpDump circumvents those flags.

Ah yes this is true and I'd forgotten that, but it was still true for broadcast tv and what is a stream of data if not a broadcast?

[...] I feel like it's quite proper for me to say "look but don't copy" -- same for a draft of a novel I'm writing or a short piece of music I've composed. [...] it seems to me quite obvious that you have no right to require that they not attach conditions to those bytes. This reasoning is known in legal circles as a maiore ad minus -- from the stronger unto the weaker. [...]

And it seems fair to ask look but don't copy, except all a computer does is copy bits all day from one place to another, its just what they do. But I do believe that those systems currently send those bytes without any requirement on my end - which is what I was getting at. There may be an implied requirement but there is not an explicit one that I can see - no login required for Hulu or Youtube content. So while you're right there may be a condition on those bytes, but to my eye the condition seems to be an internet connection. To which you'll say, but the video has a format and that format has a meaning and so we must re-implement macro-vission for the digital age!

And to that I say NO - don't go back to the bad old days. I've got more interesting things to do with that data which I shouldn't have to purchase it 12 times because you can't see past your nose.

Is the DMCA unconstitutional because it violates a particular provision of the Constitution or just because it's atrocious? People don't like to hear this from lawyers, but the fact is that the Constitution allows many shitty things (it is, after all, manifestly imperfect).

You've got a leg up on me here because I personally avoid this crap like the plague usually... But... How about this, the constitution requires that copyright be for a *limited* amount of time, I could argue they are preventing this. Though thats a weak argument I'm out of time at work and my internet is busted at home thanks to Comcast's crappy service.

Comment Re:Copyright law? (Score 1) 203

Maybe it is a classic is/ought problem as you put it, but my comment wasn't directed at your factual grandparent comment. A discussion can have more then just fact but also opinions.

In your post you said: this is an unsettled area of law. Since it would be a rather boring discussion without opinion (especially here) I think we can move passed that point eh? Now onto something more interesting...

I disagree very strenuously with the notion that this point alone proves that consumers ought to be able copy content marked 'display only'

To which I would beg the question, why not? The makers of rtmpDump don't seem any different then those of the vcr or camera to me. I don't believe there is any signed agreement by the site and the user to only use the Adobe certified player software and so long as they send the bytes to me they can have no complaint on how I use (display) those bits on my end (as a user). Now with the advent of the DMCA - an atrocious law that should be declared in part or whole as unconstitutional - there is a legal ground for attacking the neo-vcr and to that I say bullocks. With no contractual agreement between any of the parties why the fed. gov. need to get involved with everything? I'm sure the ass hats would like to come after me for my DTV capture devices too, bugger them. I shouldn't even have to utter the words fair use. I welcome the diamond age.

Comment Re:Copyright law? (Score 1) 203

They way you describe it it really sounds like the DMCA can be used to create an Evil Bit standard backed by the full power of legislature...

That is exactly what the DMCA is for, the creation of the evil bit - see HDTV's magic flag bullshit, or in this case, a stream flag or whatever. Its all really stupid because ultimately displayable content is copyable and thats what they refuse to realize.

In some games you can turn it off, others you can't, but in this game it doesn't matter because there isn't any. Check out these images from the game. I searched, I couldn't find any that had any blood even. If we were talking about COD5 which has lots and lots of blood plus blown of arms and legs and torsos even - you would have something to talk about, but this game doesn't even have any that I can see.

Submission + - U.S. encouraging use of DDT... in other countries (zdnet.com) 2

suraj.sun writes: Do as I say, not as I do. That's the situation with DDT which the American government is subsidizing for use in countries fighting malaria. The DDT is now beign widely used inside homes and other buildings in nations where malaria is a major health hazard ( http://www.eurekalert.org/pub_releases/2009-05/uoc--uuo050309.php ).

And now it occurs to some that it might be good to know what this DDT is doing to the people and the environment where it's being used. Duh.

This is the same DDT that is banned for use in over 160 countries. The same DDT that was heling drive Brown Pelicans, Bald Eagles and Peregrines toward extinction in North America. The same DDT that even our chemically dependent US banned...in 1972.

There's no manufacturing of DDT in the U.S. anymore, but one of our old plants was dismantled and moved to Indonesia where it still cranks out potent DDT ( http://oregonstate.edu/~muirp/pesthist.htm ).
