Happy Culture Freedom Day!
Sat, 18 May 2013 09:25:00
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."

RPiCluster: Another Raspberry Pi Cluster, With Neat Tricks
Sat, 18 May 2013 06:20:00
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."

NASA Meteoroid-Spotting Program Captures Brightest-Yet Moon Impact
Sat, 18 May 2013 03:12:00
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.

Password Strength Testers Work For Important Accounts
Sat, 18 May 2013 00:33:00
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."

Crowdsourced Network Planning For Connection-Bridging Startup
Fri, 17 May 2013 23:29:00
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."
