About two days ago, I was poking around with OpenSSL to find a way to mitigate Heartbleed. I soon discovered that in its default config, OpenSSL ships with exploit mitigation countermeasures, and when I disabled the countermeasures, OpenSSL stopped working entirely. That sounds pretty bad, but at the time I was too frustrated to go on. Last night I returned to the scene of the crime.
I love @securityhulk. This ssl mess is making for some lols.
EASY TO RECOVER FROM SSL BUG. JUST REVOKE PRIVATE KEYS, AND ANY DATA SENT THAT EVER TRAVEL OVER SSL SINCE BUG INTRODUCED. EASY PEASY.
Audio nerds: 24-bit/192kHz distribution is better right? Nope:
Monty at xiph.org:
Articles last month revealed that musician Neil Young and Apple’s Steve Jobs discussed offering digital music downloads of ‘uncompromised studio quality’. Much of the press and user commentary was particularly enthusiastic about the prospect of uncompressed 24 bit 192kHz downloads. 24⁄192 featured prominently in my own conversations with Mr. Young’s group several months ago.
Unfortunately, there is no point to distributing music in 24-bit/192kHz format. Its playback fidelity is slightly inferior to 16⁄44.1 or 16⁄48, and it takes up 6 times the space.
There are a few real problems with the audio quality and ‘experience’ of digitally distributed music today. 24⁄192 solves none of them. While everyone fixates on 24⁄192 as a magic bullet, we’re not going to see any actual improvement.
See this fantastic video for a walk through of why stair stepping is a total myth. (Yes you should still record and produce at 24-bit, due to headroom for not worrying about clipping. but mastering (a properly centered mix) to 16bit doesn’t lose anything).
Stephen Wolfram introduces the Wolfram Language in this video that shows how the symbolic programming language enables powerful functional programming, querying of large databases, flexible interactivity, easy deployment, and much, much more.
Natasha Singer in the NYT:
Dr. Bell’s title at Intel, the world’s largest producer of semiconductors, is director of user experience research at Intel Labs, the company’s research arm. She runs a skunk works of some 100 social scientists and designers who travel the globe, observing how people use technology in their homes and in public. The team’s findings help inform the company’s product development process, and are also often shared with the laptop makers, automakers and other companies that embed Intel processors in their goods.
In 1989, Shawn Rudiman started production work with Ed Vargo as part of the seminal Industrial group T.H.D. (Total Harmonic Distortion). This EBM/Elektro unit became quite popular in the EBM/Industrial music scene of the early to mid 90′s. They released 4 full-length albums, countless remixes and compilation releases on both European and domestic labels. During these formative years, Shawn developed a fascination with vintage music machines. In 1997, he decided to stray from his Industrial-EBM roots to explore the depths of pure rhythm and sounds in Techno music. Rudiman’s all live sets of non-stop, improvised techno became his trademark. His innate understanding of hardware drum machines, sequencers, samplers and synthesizers gave his performances the fluidity and smoothness of any DJ set, but entirely flexible in direction and tempo (well before the introduction of software live applications). These performances gained international attention throughout the Techno community and became the stuff of legend.
Today he resides in the Midwest, still releasing records and remixes. Always a consummate studio enthusiast, Shawn maintains, repairs and builds analog and vintage synthesizers while keeping a busy international touring schedule.
Gender Swap is an experiment that uses themachinetobeanother.org/ system as a platform for embodiment experience (a neuroscience technique in which users can feel themselves like if they were in a different body). In order to create the brain ilusion we use the immersive Head Mounted Display Oculus Rift, and first-person cameras. To create this perception, both users have to synchronize their movements. If one does not correspond to the movement of the other, the embodiment experience does not work. It means that both users have to constantly agree on every movement they make. Through out this experiment, we aim to investigate issues like Gender Identity, Queer Theory, feminist technoscience, Intimacy and Mutual Respect.
Fantastic profile of one of my favorite artists:
Joshua Hammer in Matter:
Adam Magyar is a computer geek, a college dropout, a self-taught photographer, a high-tech Rube Goldberg, a world traveler, and a conceptual artist of growing global acclaim. But nobody had ever suggested that he might also be a terrorist until the morning that he descended into the Union Square subway station in New York.

Not a fan of the creative, but the tech is cool.
Stuart Minor Benjamin in the University of Pennsylvania Law Review:
More and more of our activity involves not merely the transmission of bits, but the transmission of bits according to algorithms and protocols created by humans and implemented by machines. Messages travel over the Internet because of transmission protocols, coding decisions determine the look and feel of websites, and algorithms determine which links, messages, or stories rise to the top of search engine results and web aggregators’ webpages. Most webpages have automated components, as do most online articles and all video games. Are these algorithm-based outputs “speech” for purposes of the First Amendment? That is, does the Free Speech Clause of the First Amendment apply to government regulation of these or other algorithm based changes to bits?
Spent about 6 hours of my day off nerding out over this guys videos. All you ever wanted to know about power turbines.

Messaging remains the centerpiece of mobile teen behavior. The number of messages exchanged monthly (SMS and MMS) hit 3,417 per teen in Q3 2011, averaging seven messages per waking hour. Teen females are holding the messaging front, sending and receiving 3,952 messages per month versus 2,815 from males.
“Little Boy” (Hiroshima Atomic Bomb) 1945
Nice set of black and white (and infrared?) photos of cold war era Weapons of Mass Destruction.

The single, blinding release of pure energy over Hiroshima, Japan, on August 6, 1945, marked a startling and permanent break with our prior understandings of the visible world. Yet for more than sixty years the technology behind the explosion has remained a state secret.
The most accurate account of the bomb’s inner workings—an unnervingly detailed reconstruction, based on old photographs and documents—has been written by a sixty-one-year-old truck driver from Waukesha, Wisconsin, named John Coster-Mullen, who was once a commercial photographer, and has never received a college degree.

Via Schneier on Security.
ETFE is temperature-resistant, lightweight (1/100th the weight of glass), recyclable, non-toxic when exposed to flame (it actually shrinks away from heat, thus helping to vent smoke out of a burning building), highly insulative, non-porous, and non-stick. Even better, its high-tensile strength makes it easy to manipulate—it can be spun into thin sheets for ease of transport then inflated on-site to create the “pillow” effect of the Aquatics Center walls. It can also be finished in varying degrees of translucence—as transparent as glass or opaque as glass bricks.

Tim Bray on Sun:
Sun is going through a lousy spell right now. Well, so is the world’s economy in general and the IT business in particular, but this is about Sun. This is my opinion about what my employer should do about it. [. . .] Sun should adopt a laser focus on building a Sun Web Suite and becoming the Web application deployment platform of choice. It’s a large space, a growing space, and one where we can win.
He is obviously absolutely right, there is no place for the old Sun in this world. However Sun does have some excellent tech, and importantly they seem to still have a lot of top engineers, so if they can manage a major restructuring they have a fighting chance.
Clay Shirky, author of Here Comes Everybody: The Power of Organizing Without Organizations, talks about the economics of organizations with EconTalk host Russ Roberts. The conversation centers on Shirky’s book. Topics include Coase on the theory of the firm, the power of sharing information on the internet, the economics of altruism, and the creation of Wikipedia.
And a great bit of discussion on representative vs. direct democracy and the possibility that networks can enable direct democracy.
