New submitter TheJish writes "The RPiCluster is a 33-node Beowulf cluster built using Raspberry Pis (RPis). The RPiCluster is a little side project I worked on over the last couple months as part of my dissertation work at Boise State University. I had need of a cluster to run a distributed simulator I've been developing. The RPiCluster is the result. I've written an informal document on why I built the RPiCluster, how it was built, and how it performs as compared to other platforms. I also put together a YouTube video of it running an MPI parallel program I created to demo the RGB LEDs installed on each node as part of the build. While there have certainly been larger RPi clusters put together recently, I figured the Slashdot community might be interested in this build as I believe it is a novel approach to the rack mounting and power management of RPis."

From a NASA press release published Friday: "For the past 8 years, NASA astronomers have been monitoring the Moon for signs of explosions caused by meteoroids hitting the lunar surface. 'Lunar meteor showers' have turned out to be more common than anyone expected, with hundreds of detectable impacts occurring every year. They've just seen the biggest explosion in the history of the program." Watch the flash for yourself.

msm1267 writes "Many popular online services have started to deploy password strength meters, visual gauges that are often color-coded and indicate whether the password you've chosen is weak or strong based on the website's policy. The effectiveness of these meters in influencing users to choose stronger passwords had not been measured until recently. A paper released this week by researchers at the University of California Berkeley, University of British Columbia, and Microsoft provides details on the results of a couple of experiments examining how these meters influence computer users when they're creating passwords for sensitive accounts and for unimportant accounts."

An anonymous reader writes "Tom's Hardware reports on the Connectify Switchboard software that "divides the user's traffic between Wi-Fi, 3G/4G and Ethernet-based connections on a packet-by-packet basis. Even a single stream — such as a Netflix movie — can be split between two or three Internet connections for a higher resolution and faster buffering." As part of its Kickstarter campaign, Connectify is geolocating their backers to optimize deployment of their servers. This is a clever way for supporters to influence the project beyond pledge levels and stretch goals, and it's actually kind of fun to watch."

First time accepted submitter iinventstuff writes "The Idaho National Laboratory has built a dirty bomb detection network out of cell phones. Camera phones operate by detecting photons and storing them as a picture. The INL discovered that high energy photons from radiological sources distort the image in ways detectable through image processing. KSL TV reports that the INL's mobile app detects radiation sources and then reports positive 'hits' to a central server. Terrorists deploying a dirty bomb will inevitably pass by people carrying cell phones. By crowdsourcing cell phones, the INL has created a potentially very large, inexpensive, and randomly mobile radiation detection grid."

New submitter Anand Radhakrishnan writes "The release candidate for the much-anticipated Linux Mint 15 'Olivia' is available for user testing. Its many new features include Cinnamon Control center, an improved login manager with HTML 5 support, a driver manager, and a lot of under-the-hood improvements. 'A new tool called MintSources, aka "Software Sources," was developed from scratch with derivative distributions in mind (primarily Linux Mint, but also LMDE, Netrunner and Snow Linux). It replaces software-properties-gtk and is perfectly adapted to managing software sources in Linux Mint. From the main screen you can easily enable or disable optional components and gain access to backports, unstable packages and source code.' This release with Cinnamon looks really tempting."

An anonymous reader writes "The Australian government has secretly censored over 1,000 web sites through a hitherto-unused internet censorship law. In April the Melbourne Free University was blocked without any explanation. Section 313 of the Telecommunications Act allows the government to close web sites without warning to "uphold laws, protect public revenue and safeguard national security". This is open to abuse as Australians only have limited free speech rights which already make it difficult for the press to report corruption."

mcleland writes "The BBC reports that Nintendo is now using the content ID match feature in YouTube to identify screencap videos of people playing their games. They then take over the advertising that appears with the video, and thus the ad revenue. Nintendo gets it all, and the creators of these videos (which are like extended fan-made commercials for the games) get nothing. Corporate gibberish to justify this: 'In a statement, the firm said the move was part of an "on-going push to ensure Nintendo content is shared across social media."'"

New submitter SessionExpired writes "Five 9th graders from Denmark have shown that garden cress won't germinate when placed near a router (Google Translation of Danish original). Article text is in Danish, but the pictures illustrate their results. The exact mechanism is still unknown (Danish original), but experts have shown interest in reproducing the experiment."

J.J. Abrams’ 2009 reboot of Star Trek was wildly successful. It raked in hundreds of millions at the box office, and revitalized the Star Trek franchise, which had languished for 7 years without a new film and 4 years without a TV presence (after 18 consecutive years of new shows). It also did something no Trek movie had done before; it made Star Trek ‘cool’ in the public consciousness. Combined, those factors ensured Abrams would get another turn at the helm of a Trek movie, and sooner rather than later. With today's release of Star Trek: Into Darkness, that trend is very likely to continue. It's a movie with all the same strengths and weaknesses of its predecessor, and if it worked before, it'll work again. Read on for our review.

Today eight members of the U.S. Congress have sent a letter to Google's Larry Page, asking him to address a number of privacy concerns about Google Glass. In the letter (PDF), they brought up the company's notorious Street View data collection incident, and asked how the company was planning to avoid a similar privacy breach with Glass. They also ask how Google is going to build Glass to protect the privacy of non-users who may not want their every public move to be recorded. Further, they ask about the security of recordings once they are made: "Will Google Glass have the capacity to store any data on the device itself? If so, will Google Glass implement some sort of user authentication system to safeguard stored data? If not, why not?" Google has until July 14th to respond.

Nerval's Lobster writes "At this week's Google I/O in San Francisco, Google CEO Larry Page stood onstage and took unscripted questions from an auditorium of conference attendees. That's an unusual move for any chief executive, the sort of thing that risks giving their PR people a heart attack. But Page wasn't up there to offer insights into strategy or drop hints about upcoming products: he wanted to talk about how negativity in the tech industry stood in the way of innovation. 'Despite the faster change we have in the industry, we're still moving slow relative to the opportunities that we have,' he said. 'And some of that, I think, has to do with the negativity. Every story I read about Google, it's us versus some other company or some stupid thing.' Being negative, he added, is not how the tech industry makes progress. But minutes later, Page couldn't resist swiping at Oracle and Microsoft. And Google's battles are just one small element in the circular firing squad that comprises most of the tech industry: Apple versus Google versus Samsung versus Microsoft versus Oracle versus Salesforce versus lots of little startups. Those battles won't fade away anytime soon, because corporations have one goal: profit. And so long as other rivals' technological innovations or marketplace maneuvers stand in the way of that profit, the lawsuits and the CEO sniping will continue. The part of Page's talk that centered on peace and love played well to the audience at Google I/O; but it's easier to argue that the true mode of the tech industry, at its core, is Darwinian competition. Do you agree?"

New submitter WillgasM writes "A bit of good news for American travelers, according to the New York Times: 'After years of criticism of the wireless service on its trains, Amtrak announced on Thursday that it had upgraded its cellular-based Wi-Fi using broadband technologies that will improve the speed and reliability of the Internet in its passenger cars.' So far the service has been rolled out on the high-speed Acela lines and a few routes in California, but they hope to have the rest of their trains upgraded by the end of Summer. We're still an order of magnitude away from high-speed rails in other countries, but it's nice to know someone's trying."

garymortimer writes "Geologists have long used seismology on the bottom of the ocean or have been throwing dynamite from snowmobiles when they look for oil. But now researchers at Centre for Integrated Petroleum Research, a joint venture between the University of Bergen and Uni Research, have found a new preferred method – using drones to map new oil reserves from the air. ... The group’s main task is to create digital maps in 3D of potential oil fields. Using laser scanners, infrared sensors and digital cameras, the researchers create realistic, virtual models. ... Pictures shot with the help of a drone complement the images from low-level terrain that the researchers already have in hand. The end result is more precise and complete 3D models."

alancronin sends this excerpt from ZDNet: "... the trend that brutally undercut BlackBerry phones during the past five years — the 'bring your own device' movement — is now driving significant sales of BlackBerry Enterprise Service (BES), the company's backend software. 'Our customers have been asking, "Can you just take what you've done on BlackBerry and put it on iOS and Android?"' said Pete Devenyi, BlackBerry's SVP of Enterprise Software. ... Secure Work Space will be an app in the Apple App Store and Google Play, pending approval from Apple and Google, respectively. It will include secure email, calendar, contacts, tasks, and document editing. It won't allow data leakage including copy and paste between Secure Work Space and the rest of the device. IT will be able to remotely wipe everything in the Secure Work Space without affecting any of the other apps or data on the person's device, in a BYOD scenario."
