Seismic risk at the Fukushima nuclear plant increased after the magnitude 9 earthquake that hit Japan last March, scientists report. The new study, which uses data from over 6,000 earthquakes, shows the 11 March tremor caused a seismic fault close to the nuclear plant to reactivate. The results are now published in Solid Earth, an open-access journal of the European Geosciences Union (EGU).

The research suggests authorities should strengthen the security of the Fukushima Daiichi nuclear power plant to withstand large earthquakes that are likely to directly disturb the region. The power plant witnessed one of the worst nuclear disasters in history after it was damaged by the 11 March 2011 magnitude 9 earthquake and tsunami. But this tremor occurred about 160 km from the site, and a much closer one could occur in the future at Fukushima.

Ahead of the anniversary of Iran’s revolution Saturday, the country’s government has locked down its already-censored Internet, blocking access to many services and in some cases cutting off all encrypted traffic on the Web of the kind used by secure email, social networking and banking sites. In response, the information-freedom-focused Tor Project is testing a new idea: Encrypted connections that don’t look encrypted. To skirt the so called “deep packet inspection” filters Iran’s government has deployed to block all Secure Sockets Layer and Transport Layer Security (SSL and TLS) encryption that protesters might use to communicate privately, Tor is trying a new kind of bridge to the Web, one the group is calling “obfsproxy,” or obfuscated proxy.

The problem with safety guidelines is that they make most playgrounds so uninteresting as to contribute to reduced physical activity.

Playgrounds don't look like they used to. Steep metal slides and wooden towers have given way to slow, plastic slides and carefully penned-in climbing contraptions.

And forget about seesaws -- they're a thing of the past.

When kids are bored by unimaginative (read: safe) playground equipment, they're less active as a result, and with childhood obesity at epidemic proportions, that's a danger, too.

Arachni uses various techniques to compensate for the widely heterogeneous environment of web applications. This includes a combination of widely deployed techniques (taint-analysis, fuzzing, differential analysis, timing/delay attacks) along with novel technologies (rDiff analysis, modular meta-analysis) developed specifically for the framework. This allows the system to make highly informed decisions using a variety of different inputs; a process which diminishes false positives and even uses them to provide human-like insights into the inner workings of web applications.

Google knows it. Viacom knows it. The Chamber of Commerce knows it. Internet democracy groups know it. BoingBoing knows it. But, the Internet hasn't been told yet -- we're going to get blown away by the end of the year. The worst bill in Internet history is about to become law. Law is very real here in the United States and legal language is often different than stated intentions -- this law would give government and corporations the power to block sites like BoingBoing over infringing links on at least one webpage posted by their users. Believe the EFF, Public Knowledge, Google when they say this bill is about much more than copyright, it's about the Internet and free speech everywhere.

At the moment, BEAST requires about two seconds to decrypt each byte of an encrypted cookie. That means authentication cookies of 1,000 to 2,000 characters long will still take a minimum of a half hour for their PayPal attack to work. Nonetheless, the technique poses a threat to millions of websites that use earlier versions of TLS, particularly in light of Duong and Rizzo's claim that this time can be drastically shortened.

If there's one point that we want to communicate to the world, it's that SSL/TLS is not computationally expensive any more. Ten years ago it might have been true, but it's just not the case any more. You too can afford to enable HTTPS for your users.

In January this year (2010), Gmail switched to using HTTPS for everything by default. Previously it had been introduced as an option, but now all of our users use HTTPS to secure their email between their browsers and Google, all the time. In order to do this we had to deploy no additional machines and no special hardware. On our production frontend machines, SSL/TLS accounts for less than 1% of the CPU load, less than 10KB of memory per connection and less than 2% of network overhead. Many people believe that SSL takes a lot of CPU time and we hope the above numbers (public for the first time) will help to dispel that.

Zfone™ is a new secure VoIP phone software product which lets you make encrypted phone calls over the Internet. Its principal designer is Phil Zimmermann, the creator of PGP, the most widely used email encryption software in the world. Zfone uses a new protocol called ZRTP, which has a better architecture than the other approaches to secure VoIP.

* Doesn't depend on signaling protocols, PKI, or any servers at all. Key negotiations are purely peer-to-peer through the media stream * Interoperates with any SIP/RTP phone, auto-detects if encryption is supported by other endpoint * Available as a "plugin" for existing soft VoIP clients, effectively converting them into secure phones * Available as an SDK for developers to integrate into their VoIP applications * IETF has published the protocol spec as RFC 6189, and source code is published

Tetsunari Iida, a former nuclear engineer who currently heads the Institute for Sustainable Energy Policies, says that the industry is dominated by a closely-knit nuclear establishment. Those who graduate from universities and graduate from schools with degrees in nuclear power engineering go on to work at power companies, energy-related manufacturers, or municipalities that host nuclear power stations. Everything comes down to personal networks, and who the graduating students go on to work for is largely influenced by the connections and interests of the students' professors. Regardless of whether the employers are public or private organizations, the newly inducted engineers are raised to become full-fledged members of the nuclear establishment.
