Submission + - US pushing local police to keep quiet on cell-phone surveillance technology (yahoo.com)

schwit1 writes: The Obama administration has been quietly advising local police not to disclose details about surveillance technology they are using to sweep up basic cellphone data from entire neighborhoods, The Associated Press has learned.

Citing security reasons, the U.S. has intervened in routine state public records cases and criminal trials regarding use of the technology. This has resulted in police departments withholding materials or heavily censoring documents in rare instances when they disclose any about the purchase and use of such powerful surveillance equipment.

Federal involvement in local open records proceedings is unusual. It comes at a time when President Barack Obama has said he welcomes a debate on government surveillance and called for more transparency about spying in the wake of disclosures about classified federal surveillance programs.

Submission + - Are the Glory Days of Analog Engineering Over? (eetimes.com)

An anonymous reader writes: Controversy has been swirling for years over the question of whether analog engineers are relevant in a digital world. Analog engineers themselves are lining up against management in the tussle over whether there really is a shrinking pool of engineers to do the work, or whether companies have unrealistic expectations. As one former analog engineer puts it, "The job descriptions for analog engineers today ask for expertise in all these analog areas, then they throw in 'must know VHDL' [a digital programming language]. Your head would explode if you had to carry all the information in your head!

Submission + - Recomendations about very cheap PC based oscilloscope

fffdddooo writes: I know it is something that people use to ask every few years, but answers get old so quickly........
I'm electronics teacher and I'm wondering if it's possible to find some oscilloscope (and why not spectrum analyser) for recommending my students to be able to work at home.
I'm thinking on something near $50-$70. The question is may be something that is not crap for these price?
Two or three years ago I'm sure the answer was no, but nowadays?
I've seen to cheap

http://www.amazon.com/VELLEMAN...
It is 200Khz oscilloscope and 75Khz spectrum analyzer... very cheap but in Khz

But

It aims to be capable of 20Mhz, 2 channel.

What do you think?

Submission + - Mesothermy in Dinosaurs (sciencemag.org)

An anonymous reader writes: An article published today in Science (http://www.sciencemag.org/content/344/6189/1268) points to the possibility that dinosaurs were mesotherms more akin to modern Tuna. Their internal temperature would have been warmer than their surrounding environment, conferring on them the ability to move more quickly than any ectotherm (“cold blooded” animal), but wouldn’t have been constant or as warm as any endoderm (“warm blooded” animal). Their energy use and thus their necessary food intake would have been greater than an ectotherm, but much less than an endotherm. In order to arrive at this possibility, bone growth rings in fossilized bone were used to establish growth rates and then compared to modern ectotherms and endotherms. Nature has a write up on this: http://www.nature.com/news/din...

Submission + - Sage produces 707-millisecond boot on Atom #3800 SoC (se-eng.com)

SageJeff writes: Sage has produced a coreboot® distribution that will start booting an operating system in 707 milliseconds on the Atom E3800 System on a Chip (SoC), said Sage Engineer Martin Roth. Sage has already authored firmware boots of 250 milliseconds to a Linux kernel on earlier-generation AMD chips and less than two seconds to a full Linux operating system boot on Intel-based laptops.
The SageBIOS programming by Sage, which designs open source firmware solutions and products, was initially a co-development with Intel as part of the Fast Boot solution for time-critical applications.

Submission + - The Oracle v. Google Appeals Court Ruling Could Break 1

rjmarvin writes: The long-running lawsuit and countersuit between Google and Oracle resulted in a ruling last month that, in no uncertain terms, could break much of the software in use today.http://sdt.bz/71372.The decision insinuates that a developer who implements a standard or specification can now be open to lawsuit by the specification's creator. The federal circuit court did leave room for fair use to be found in Google's replication of the Java APIs. This fair use will be decided by Judge William Alsup, but may not matter in the end if the Supreme Court gets involved. If it sounds like this type of ruling would break the entire foundation of software development, that's because it does.

Submission + - Tesla releases electric car patents to the public (teslamotors.com)

mknewman writes: Yesterday, there was a wall of Tesla patents in the lobby of our Palo Alto headquarters. That is no longer the case. They have been removed, in the spirit of the open source movement, for the advancement of electric vehicle technology.

Tesla Motors was created to accelerate the advent of sustainable transport. If we clear a path to the creation of compelling electric vehicles, but then lay intellectual property landmines behind us to inhibit others, we are acting in a manner contrary to that goal. Tesla will not initiate patent lawsuits against anyone who, in good faith, wants to use our technology.

Submission + - Austrian Teen at Heart of TweetDeck Mess Says it Was All a Mistake

Trailrunner7 writes: The last 24 hours have been a sad, scary and frustrating time for an 19-year-old aspiring programmer in Austria who found himself smack in the middle of Wednesday’s TweetDeck mess—all because of a Unicode heart.

Twitter’s real-time account dashboard was taken down for a brief time yesterday before a cross-site scripting vulnerability in the TweetDeck Chrome plug-in was properly addressed. But not before code exploiting the bug in a benign manner spread to Twitter users worldwide.

Ground zero for the incident was the Austrian teen who identified himself only as Florian to Threatpost. The youngster said things began yesterday when he tweeted out an HTML hearts symbol (&hearts) that was graphically displayed in the message.

“TweetDeck is not supposed to display this as an image, because it’s simple text, which should be escaped to “♥,” he said.

“I didn’t know that there is such a big problem. So I experimented with this in a public environment, there was no reason not to do so,” Florian said. “And that was the point where I reported this to TweetDeck.

“TweetDeck actually did not react in any way,” Florian said. “Their next Tweet was saying that there is a security-issue and the users should log in again.”

Submission + - Facebook Lets Users Opt Out of Targeted Ads (nbcnews.com)

mpicpp writes: Facebook users who are annoyed by the targeted ads that pop up in their News Feed will soon have more control over what they see.

Like Google, Facebook collects all kinds of information on its users and uses that information to serve up targeted ads. For some people, especially privacy advocates, it seemed a little creepy to have a social network tracking a user’s activity and then using that data to sell them stuff. On Thursday, Facebook announced that users will soon be able to opt out of that targeted ad system through controls in their Web browser and iOS and Android phones.

Facebook will also show users what information they have collected about them and let them edit the kinds of ads they want to see. If someone is confused about why they are seeing an ad for P.F. Chang's, for example, they can simply click on "Why am I seeing this ad?"

Submission + - WSJ: Facebook to Advertisers: More Data Coming

psybre writes: A Wall Street Journal article details Facebook's plans for sharing their information with advertisers. The company has been gathering user's browsing habits. While used in the past only for security reasons, they intend to provide this information to advertisers soon. An industry analyst was quoted that, "By bringing in data about their users' browsing habits and app usage, they are creating an even more complete profile of each person."

The longer a bacterium or virus has been present on the planet, the more likely it is that animals will have inherited a natural defense mechanism to cope with it. That's not an absolute; our inherited resistance to specified pathogens might be 'forgotten' over the course of centuries or millenia, but those immunities are theorized to be the reason that pathogens also evolve. In effect, pathogens learn to live in us. We learn how to evict them. They learn how to sneak back in. We learn how to catch them and eject them.

Yes, I know it's not a very scientific or thorough explanation. If you accept the principals of the theory of evolution and the concept of genetic drift, it makes sense. In any event, I suspect the modern forms of this bacteria are more virulent than their primitive ancestors.
