Ask Slashdot: Software For Learning About Data Transmission? 79

Posted by timothy
from the take-this-string-and-those-cans dept.
bellwould writes "In teaching information tech to a 13-year-old with autism spectrum disorder (ASD), I've found she's wildly interested in the details of data transmission but not programming. We've had limited success with command-line tools like traceroute and tcpdump, but now I'm seeking tips/advice on software that may help her explore and visualize things like transmission protocols." What would you recommend?

4 Microsoft Engineers Predicted DRM Would Fail 10 Years Ago 142

Posted by Soulskill
from the not-that-companies-have-listened-yet dept.
An anonymous reader writes "Ars is running an article about a paper written just over a decade ago by four engineers at Microsoft. In it, they talk about the darknet, and how it applies to distributing content online. They correctly predicted the uselessness of DRM: 'In the presence of an infinitely efficient darknet — which allows instantaneous transmission of objects to all interested users — even sophisticated DRM systems are inherently ineffective.' The paper's lead author, Peter Biddle, said he almost got fired over the paper at the time. 'Biddle tried to get buy-in from senior Microsoft executives prior to releasing the paper. But he says they didn't really understand the paper's implications — and particularly how it could strain relationships with content companies — until after it was released. Once the paper was released, Microsoft's got stuck in bureaucratic paralysis. Redmond neither repudiated Biddle's paper nor allowed him to publicly defend it.' The paper itself is available in .DOC format."

Syrian Malware Servers Survive, Then Die 23

Posted by Soulskill
from the like-most-things dept.
Nerval's Lobster writes "A massive outage knocked Syria's Internet offline Nov. 29 — with the exception of five servers implicated in serving malware earlier this year. But the next day, those five servers went dark as well. Internet analytics firm Renesys suggested late Nov. 29 that those five servers were likely offshore. 'Now, there are a few Syrian networks that are still connected to the Internet, still reachable by traceroutes, and indeed still hosting Syrian content,' the company wrote in a blog post. 'These are five networks that use Syrian-registered IP space, but the originator of the routes is actually Tata Communications. These are potentially offshore, rather than domestic, and perhaps not subject to whatever killswitch was thrown today within Syria.' By the morning of Nov. 30, those five servers went offline. 'The last 5 networks belonging to Syria, a set of smaller netblocks previously advertised by Tata Communications, have been torn down and are no longer routed,' Renesys wrote." CloudFlare has a blog post confirming that the Syrian government was responsible for flipping the switch, contrary to their claims. Meanwhile, Anonymous has started targeting the Syrian government's remaining websites and helping to get communications channels flowing out of Syria. Google is reminding people of its Speak2Tweet service, which lets people post to Twitter through voicemail over still-functioning phone lines.

Raided For Running a Tor Exit Node 325

Posted by Soulskill
from the internet-over-tor-is-a-series-of-tubers dept.
An anonymous reader writes "A Tor Exit node owner is being prosecuted in Austria. As part of the prosecution, all of his electronics have been held by the authorities, including over 20 computers, his cell phone and hard disks. 'During interview with police later on Wednesday, Weber said there was a "more friendly environment" once investigators understood the Polish server that transmitted the illegal images was used by Tor participants rather than by Weber himself. But he said he still faces the possibility of serious criminal penalties and the possibility of a precedent that Tor operators can be held liable if he's convicted.' This brings up the question: What backup plan, if any, should the average nerd have for something like this?"

from the all-colors dept.
KermMartian writes "In what seems to be an accelerating arms race for graphing calculator supremacy between Texas Instruments and Casio, the underdog Casio has fired a return salvo to the recently-announced TI-84 Plus C Silver Edition. The new ClassPad fx-CP400 has a massive color touchscreen and a Matlab-esque CAS. Though not accepted on the SAT/ACT, will such a powerful device gain a strong following among engineers and professionals?"

Silicon Valley's Dirty Little Secret: Age Bias 375

Posted by Soulskill
from the get-off-my-lawn dept.
MightyMait writes "With my 40th birthday coming up, seeing this article makes me happy I have a good job (and a little wary of having to find another). From the article: '[T]he start-up ethos extols fresh ideas and young programmers willing to toil through the night. Chief executives in their 20s, led by Facebook founder Mark Zuckerberg, are lionized, in part because of their youth. Many investors state bluntly that they prefer to see people under 40 in charge. Yet the youth worship undercuts another of Silicon Valley's cherished ideals: that anyone smart and driven can get ahead in what the industry likes to think of as an egalitarian culture. To many, it looks like simple age discrimination - and it's affecting people who wouldn't fit any normal definition of old. "I don't think in the outside world, outside tech, anyone in their 40s would think age discrimination was happening to them," says Cliff Palefsky, a San Francisco employment attorney who has fielded age-discrimination inquiries from people in their early 40s. But they feel it in the Bay Area, he said, and it's "100 percent due to the new, young, tech startup mindset."'"

Red Light Cameras Raise Crash Risk, Cost 499

Posted by Soulskill
from the time-to-test-red-light-clown-technology dept.
concealment writes with news of dissatisfaction with a pilot program for stoplight-monitoring cameras. The program ran for several years in New Jersey, and according to a new report, the number of car crashes actually increased while the cameras were present. "[The program] appears to be changing drivers’ behavior, state officials said Monday, noting an overall decline in traffic citations and right-angle crashes. The Department of Transportation also said, however, that rear-end crashes have risen by 20 percent and total crashes are up by 0.9 percent at intersections where cameras have operated for at least a year. The agency recommended the program stay in place, calling for 'continued data collection and monitoring' of camera-monitored intersections. The department’s report drew immediate criticism from Assemblyman Declan O’Scanlon, R-Monmouth, who wants the cameras removed. He called the program 'a dismal failure,' saying DOT statistics show the net costs of accidents had climbed by more than $1 million at intersections with cameras." Other cities are considering dumping the monitoring tech as well, citing similar cost and efficacy issues.

What's It Like To Pilot a Drone? a Bit Like Call of Duty 170

Posted by Soulskill
from the make-it-like-minecraft-and-you've-got-yourself-a-soldier dept.
Velcroman1 writes "Teenagers raised on Call of Duty and Halo might relish flying a massive Predator drone — a surprisingly similar activity. Pilots of unmanned military aircraft use a joystick to swoop down into the battlefield, spot enemy troop movements, and snap photos of terror suspects, explained John Hamby, a former military commander who led surveillance missions during the Iraq War. 'You're always maneuvering the airplane to get a closer look,' Hamby said. 'You're constantly searching for the bad guys and targets of interest. When you do find something that is actionable, you're a hero.' Yet a new study at the Massachusetts Institute of Technology found real-life drone operators can become easily bored. Only one participant paid attention during an entire test session, while even top performers spent a third of the time checking a cellphone or catching up on the latest novel. The solution: making the actual drone mission even more like a video game."

Rise of the Online Code Schools 98

Posted by samzenpus
from the from-the-comfort-of-your-own-home dept.
Barence writes "When it comes to programming, the classroom is moving online. A new wave of start-ups has burst onto the scene over the last year, bringing interactive lessons and gamification techniques to the subject to make coding trendy again. From Codecademy — and its incredibly successful Code Year initiative — to Khan Academy, Code School and Udacity, online learning is now sophisticated and high-tech — but is it good enough to replace the classroom? 'We are the first five or six chapters in a book,' says Code School's Gregg Pollack in this exploration of online code classes, but with the number of sites and lessons growing by the week that might not be the case for long."

Does Even Amazing Partisan Tech Deserve Applause? 209

Posted by samzenpus
from the one-sided-applause dept.
theodp writes "The press has been filled with wide-eyed articles about how Obama's tech team pulled out the stops in their race against the Republicans. But as exciting as some of the new techniques dreamed up may be, Tom Steinberg points out it's important to reflect on the difference between choosing to use tech skills to win a particular fight, versus trying to improve the workings of the democratic system, or helping people to self-organize and take some control of their own lives. 'I am still filled with an excitement about the prospects for non-partisan technologies that I can't muster for even the coolest uses of randomized control trial-driven political messaging,' writes Steinberg. 'The reason why all comes down to the fact that major partisan digital campaigns change the world, but they don't do it in the way that services like eBay, TripAdvisor and Match.com do. What all these sites have in common – helping people sell stuff they own, find a hotel, or a life partner – is that they represent a positive change in the lives of millions of people that is not directly opposed by a counter-shift.'"

Microsoft Granted Patent For Augmented Reality Glasses 89

Posted by Unknown Lamer
from the not-tonight-shades dept.
another random user writes with an excerpt from the BBC about Microsoft's vision for augmented reality glasses: "A patent granted to the U.S. tech firm describes how the eyewear could be used to bring up statistics over a wearer's view of a baseball game or details of characters in a play. The newly-released document was filed in May 2011 and is highly detailed. ... Although some have questioned how many people would want to wear such devices, a recent report by Juniper Research indicated that the market for smart glasses and other next-generation wearable tech could be worth $1.5bn by 2014 and would multiply over following years." Noticeable differences from Google's version: two lenses, a wrist computer, and wires.

Could Testing Block Psychopaths From Senior Management? 422

Posted by timothy
from the self-aggrandizing-liars-with-golden-parachutes dept.
Freshly Exhumed writes "Dr. Clive Boddy believes that increasingly fluid corporate career paths have helped psychopaths conceal their disruptive workplace behavior and ascend to previously unattainable levels of authority. Boddy points out psychopaths are primarily attracted to money, status and power, currently found in unparalleled abundance in the global banking sector. As if to prove the point, many of the world's money traders self identify as the "masters of the universe." Solution? Screening with psychological tests. Who would pay for it? The insurance industry." The tech world has plenty of company heads who've been called psychopaths, too — but would you want to actually change that?

UK To Use "Risk-Profiling Software" To Screen All Airline Passengers and Cargo 222

Posted by samzenpus
from the listen-to-the-computer dept.
dryriver writes "The BBC reports: 'The UK branch of an American company — SAS Software — has developed a hi-tech software program it believes can help detect and prevent potentially dangerous passengers and cargo entering the UK using the technique known as 'risk profiling.' So, what exactly is risk profiling and can it really reduce the risk of international terrorism? Risk profiling is a controversial topic. It means identifying a person or group of people who are more likely to act in a certain way than the rest of the population, based on an analysis of their background and past behavior — which of course requires the collection of certain data on people's background and behavior to begin with. When it comes to airline security, some believe this makes perfect sense. Others, though, say this smacks of prejudice and would inevitably lead to unacceptable racial or religious profiling — singling out someone because, say, they happen to be Muslim, or born in Yemen. The company making the Risk-Profiling Software in question, of course, strongly denies that the software would single people out using factors like race, religion or country of origin. It says that the program works by feeding in data about passengers or cargo, including the Advanced Passenger Information (API) that airlines heading to Britain are obliged to send to the UK Border Agency (UKBA) at 'wheels up' — the exact moment the aircraft lifts off from the airport of departure. Additional information could include a combination of factors, like whether the passenger paid for their ticket in cash, or if they have ever been on a watch list or have recently spent time in a country with a known security problem. The data is then analyzed to produce a schematic read-out for immigration officials that shows the risk profile for every single passenger on an incoming flight, seat by seat, high risk to low risk.'"

Why Iron Dome Might Only Work For Israel 377

Posted by samzenpus
from the not-for-everyone dept.
An anonymous reader writes "Many this week have declared Israel's American financed Iron Dome rocket defense system a success. Some have even gone so far to declare it a vindication of Ronald Reagan's 1980's Star Wars missile defense system. Pundits have even gone so far to assume the system could be sold to other nations. However, the Iron Dome may not be the game changer many are making it out to be. Taking out unsophisticated rockets is quite different than advanced missiles: '...the technical and strategic challenges of shooting down ballistic missiles differ considerably from those of shooting down unguided rockets. BMD shares with rocket defense some common technological ground; both require fast reaction time and impressive sensor capabilities, and the Iron Dome project has benefited from technical work on missile defense. However, ballistic missiles in flight behave differently from unguided, sub-atmospheric rockets.'"

Ask Slashdot: How Should Tech Conferences Embrace Diversity? 343

Posted by Soulskill
from the at-least-one-romulan-for-every-human dept.
An anonymous reader writes "The Register is reporting on how debate over diversity has managed to get a Ruby conference in the UK cancelled, as the speakers were 100% white male. The person running the conference, Chuck Hardy, said he 'was not prepared to put [himself] in the position of legal liability and cost ramifications if a sponsor were to pull out under social media strain.' He added, 'The ramifications of comments such as race and gender can have financial and legal consequences for the conference organizer. Raise these issues but allow the conference organizers the chance to highlight and act on these industry level issues. Accusation and slander is not a solution.' Should conferences embrace diversity from the start, or should they go forward even if the speakers are all of the same denomination? How far do we have to go to ensure we are diverse?"
