Poll: Majority Of Americans Approve Of Sending Congress To Syria | The Onion - America’s Finest News Source

The New York Times/CBS News poll showed that though just 1 in 4 Americans believe that the United States has a responsibility to intervene in the Syrian conflict, more than 90 percent of the public is convinced that putting all 535 representatives of the United States Congress on the ground in Syria—including Senate pro tempore Patrick Leahy, House Speaker John Boehner, House Majority Leader Eric Cantor, and House Minority Leader Nancy Pelosi, and, in fact, all current members of the House and Senate—is the best course of action at this time.

“I believe it is in the best interest of the United States, and the global community as a whole, to move forward with the deployment of all U.S. congressional leaders to Syria immediately,” respondent Carol Abare, 50, said in the nationwide telephone survey, echoing the thoughts of an estimated 9 in 10 Americans who said they “strongly support” any plan of action that involves putting the U.S. House and Senate on the ground in the war-torn Middle Eastern state. “With violence intensifying every day, now is absolutely the right moment—the perfect moment, really—for the United States to send our legislators to the region.”

“In fact, my preference would have been for Congress to be deployed months ago,” she added (...) regardless of whether the Assad regime used chemical weapons or not.

In fact, 91 percent of those surveyed agreed that the active use of sarin gas attacks by the Syrian government would, if anything, only increase poll respondents’ desire to send Congress to Syria.

De-Anonymizing Alt.Anonymous.Messages - ritter.vg

De-Anonymizing Alt.Anonymous.Messages - ritter.vg

http://ritter.vg/blog-deanonymizing_amm.html

For the past four years I’ve been working on a project to analyze Alt.Anonymous.Messages, and it was finally getting to a point where I thought I should show my work. I just finished presenting it at Defcon, and because a lot of the people I know are interested in this were not able to make it, I’m making the slides, and more importantly the speaker notes, available for download. This kind of kills the chance anyone will actually watch the video, but that’s all right.

The slides cover the information-theoretic differences between SSL, Onion Routing, Mix Networks, and Shared Mailboxes. It talks about the size of the dataset I analyzed, and some broad percentages of the types of messages in it (PGP vs Non-PGP, Remailed vs Non-Remailed). Then I go into a large analysis of the types of PGP-encrypted messages there are. Messages encrypted to public keys, to passwords and passphrases, and PGP messages not encrypted at all!

In recent years, new encryption programs like Tor, RedPhone, TextSecure, Cryptocat, and others have taken the spotlight - but the old guard of remailers and shared inboxes are still around. Alt.Anonymous.Messages is a stream of thousands of anonymous, encrypted messages, seemingly opaque to investigators. For the truly paranoid, there is no communication system that has better anonymity - providing features and resisting traffic analysis in ways that Tor does not. Or so is believed. After collecting as many back messages as possible and archiving new postings daily for four years, several types of analysis on the contents of alt.anonymous.messages will be presented and several ways to break sender and receiver anonymity explained. Messages will be directly and statistically correlated, communication graphs drawn, and we’ll talk about what challenges the next generation of remailers and nymservs face, and how they should be designed.

But what I keep coming back to is the fact that we have no anonymity network that is high bandwidth, high latency. We have no anonymity network that would have let someone securely share the Collateral Murder video, without Wikileaks being their proxy. You can’t take a video of corruption or police brutality, and post it anonymously.
Now I hear you arguing with me in your heads: Use Tor and upload it to Youtube. No, youtube will take it down. Use Tor and upload it to MEGA, or some site that will fight fradulent takedown notices. Okay, but now you’re relying on the good graces of some third party. A third party that is known to host the video, and can be sued. Wikileaks was the last organization that was willing to take on that legal fight, and now they are no longer in the business of hosting content for normal people.
And you can say Hidden Service and I’ll point to size-based traffic analysis and confirmation attacks that come with a low-latency network, never mind Ralf-Phillip Weinmen’s amazing work the other month that really killed Hidden Services. We can go on and on like this, but I hope you’ll at least concede the point that what you are coming up with are work-arounds for a problem that we lack a good solution to.

“The architecture of Sound”, par #Tanya_Harris (interview par #Soundry)

You made recordings of churches around London to eventually produce your own sound patterns. How exactly did you record these different acoustics and turn them into visible vibration ?

Inspired by Alvin Lucier, a music composer who discovered a technique to record the resonant frequency of a space. I recorded the silence of the church and then played this recording back into the church while re-recording it. I repeated this process over and over again until the resonant frequencies of each church became audible.

Building my own cymatic experiment enabled me to see the hidden geometry of sound. It consists of a 450 watt amplifier that I made which is attached to a 15 inch bass speaker cone. I vaccum formed the speaker with thin plastic which allowed me to put water inside the speaker. When frequencies are played through the speaker- the water arranges itself into geometric patterns.

Your photographs of oscillating water surfaces are beautiful: how did you catch them and how did you then turn them back into stone ?

I took these pictures in a dark environment. I used an angle-poise magnifying lamp and positioned it over the water in the speaker so that it created a ring of light on the water. I removed the magnifying glass and took the pictures through the centre of the circular light.

Having photographed the pattern, I created a vector and laser graved the pattern onto the stone that the churches were made from.
