Blug_fred writes "For the second edition, today is the time to celebrate Culture Freedom Day. While not as popular as HFD or SFD, celebrating Free Culture involves finding Free Culture artists, inviting them to your place and having them perform, display or talk about what their creation(s). Of course you can always simply project a couple of Free Culture movies and launch a discussion about their business models. Either way you can find all the happening for today here on the map and we sincerely hope there will be something of interest near you."

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."'"

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."

hypnosec writes "Mozilla is not going ahead with its plans to block third-party cookies by default in the Beta version of its upcoming Firefox 22. Mozilla needs more time to analyze the outcome of blocking these cookies. The non-profit organization released Firefox Aurora on April 5 with a patch by Jonathan Mayer built into it which would only allow cookies from those websites which the user has visited. The patch would block the ones from sites which hadn't been visited yet. The reason for Mozilla's change in plans is that they're currently looking into 'false positives.' If a user visits one part of a group of site, cookies from that part will be allowed, but cookies from related sites in the group may be blocked, and they're worried it will create a poor user experience. On the other side of the coin, there are 'false negatives.' Just because a user may have visited a particular site doesn't mean she is comfortable with the idea of being tracked."

An anonymous reader writes "A meta-study published yesterday looked at over 12,000 peer-reviewed papers on climate science that appeared in journals between 1991 and 2011. The papers were evaluated and categorized by how they implicitly or explicitly endorsed humans as a contributing cause of global warming. The meta-study found that an overwhelming 97.1% of the papers that took a stance endorsed human-cause global warming. They also asked the 1,200 of the scientists involved in the research to self-evaluate their own studies, with nearly identical results. In the interest of transparency, the meta-study results were published in an open access journal, and the researchers set up a website so that anybody can check their results. From the article: '... a memo from communications strategist Frank Luntz leaked in 2002 advised Republicans, "Should the public come to believe that the scientific issues are settled, their views about global warming will change accordingly. Therefore, you need to continue to make the lack of scientific certainty a primary issue in the debate." This campaign has been successful. A 2012 poll from U.S. Pew Research Center found less than half of Americans thought scientists agreed humans were causing global warming. The media has assisted in this public misconception, with most climate stories "balanced" with a "skeptic" perspective. However, this results in making the 2–3% seem like 50%. In trying to achieve "balance," the media has actually created a very unbalanced perception of reality. As a result, people believe scientists are still split about what's causing global warming, and therefore there is not nearly enough public support or motivation to solve the problem.'"

dp619 writes "The tactic of patenting open source software to guard against patent trolls and the weaponization of corporate patent portfolios is gaining momentum in the FOSS community. Organizations including the Open Innovation Network, Google and Red Hat have built defensive patent portfolios (the latter two are defending their product lines). This approach has limitations. Penn State law professor Clark Asay writes in an Outercurve Foundation blog examining the trend, 'Patenting FOSS may help in some cases, but the nature of FOSS development itself may mean that patenting some collaboratively developed inventions is inherently more difficult, if not impossible, in many others. Consequently, strategies for mitigating patent risk that rely on FOSS communities patenting their technologies include inherent limitations. It's not entirely clear how best to reform patent law in order to better reconcile it with alternative models of innovation. But in the meantime, FOSS still presents certain advantages that, while dimmed by the prospect of patent suits, remain significant.'"
