From a 2009 Southern Poverty Law Center report, David Arenberg describes his life as a Jewish guy inside a heavily racially segregated state prison where he faces violence and even death if he doesn't eat with the Aryan Brotherhood. Arenberg uses the essay to jump into a harrowing view into the rise of serious, politicized neo-Nazi skinheads in prison -- guys who make the Aryan Brotherhood look like moderates.

Not that there's anywhere else I could eat. The prison yard is broken down into five distinct racial categories and segregation is strictly enforced. There are the "woods" (short for peckerwoods) that encompass the whites, the "kinfolk" (blacks), the "Raza" (American-born people of Mexican descent), the "paisas" (Mexico-born Mexicans), and the "chiefs" (American Indians). Under the strict rules that govern interracial relations, different races are allowed to play on the same sports teams but not play individual games (e.g., chess) together; they may be in each others' cubicles together if the situation warrants but not sit on each others' beds or watch each others' televisions. They may go to the same church services but not pray together. But if you accidentally break one of these rules, the consequences are usually pretty mild: you might get a talking to by one of the heads (who, of course, claims exemption from this rule himself), or at worst, a "chin check."
Eating with another race, however, is a different story. It is an inviolate rule that different races may not break bread together under any circumstances.
DroneShield is an indieGOGO project from a DC aerospace engineer that aims to build a tiny, net-connected drone-detector/identifier. Based on a Raspberry Pi gumstick computer, it uses a mic to detect the audio signature of nearby drones, and then communicates about its findings over the Internet. The project promises free/open hardware and software specs on its main site. Ars Technica's Cyrus Farivar spoke to Chris Kyriakakis, a USC electrical engineering prof, who suggests the project is feasible, but believes it will need an array of mics for accurate identification. But John Franklin, who's running the effort, says the device will produce useful -- if imperfect -- output even with one mic.
The fully assembled drone detector costs at least $69 as a pre-order (as with all crowdfunded project, it's important to remember that you may never get your device). The project goal is to get them down to $20. For my part, I wonder how this would perform against active countermeasures: it's one thing to detect drones that aren't making any effort to remain hidden or fool detectors about which drone they are, but what about a drone that uses some technology (from playing a recording of a different drone to full-on modifications of its engines and blades) to sound different?
In any event, I expect that this is an intermediate step on the way to this thing disappearing into our phones and becoming an app that would make use of its open database of drone acoustic signatures. I can easily imagine a Drone Foursquare made by volunteers who upload drone "sightings" to realtime maps as they move around the world. Read the rest
The Golden Ratio — that geometric expression of the Fibonacci sequence of numbers (1, 1, 2, 3, 5, etc.) — has influenced the way master painters created art and can be spotted occurring naturally in the seed arrangement on the face of a sunflower. But its serendipitous appearances aren't nearly as frequent as pop culture would have you believe, writes Samuel Arbesman at The Nautilus. In fact, one of the most common examples of mathematical perfection — the chambered nautilus shell — actually isn't. Even math can become part of the myths we tell ourselves as we try to create meaning in the universe.
I only have to change the time zone when I travel, which can be done at the push of a button.
It's waterproof and does the things most digital watches do (alarms, stopwatch, etc.). It also has a compass, barometer, altimeter, and thermometer, all of which get used when I go backpacking. The compass gets used the most. The barometer is good for predicting weather changes.
I have one small gripe about this watch. It recently needed to be repaired because it displayed “OPEN” on the front. A metal plate inside had shifted. I was able to fix it easily with a PH000 screwdriver.
Its a very tough watch that has been through a lot. After 5 years I still enjoy it immensely. -- Carl Mixon
On IO9, Vincze Miklós has rounded up a beautiful gallery of photos of vintage science labs, from the Renaissance to Pasteur and Edison and ENIAC. Labs like these are the source of the shared dream of what science looks like that dominates our contemporary consciousness, even though most labs today look very different (science, like many other tasks today, looks like: a person with headphones and bad posture typing at a laptop and periodically clutching at her wrists).
My sculptures are created digitally using a variety of tools and processes. They are then produced as 3D printed objects in nylon and bronze. I also create high resolution computer renderings of them, which are like simulated photographs. These are produced as 2D digital prints on a variety of surfaces.
Recently I created a simulation of the nylon material used in 3D printing. The image above is a "physically based" computer rendering of my sculpture, "Frank's Flowing Self Awareness". Notice the scattering of the light through the translucent nylon material. In computer graphics, this property is called sub-surface scattering (SSS).
The concept behind all this is the dissolution of traditional boundaries through technology. I'm making art that is simultaneously 2d, 3d, sculpture, painting, photography, photorealistic, abstract, real and virtual.

For decades, the unimaginably wealthy residents of Malibu's oceanfront mansions have been using sneaky tricks to prevent the public from accessing the beautiful beaches in the area. But, as reported in USA Today, "The California Coastal Commission, a powerful state environmental agency, says the law allows everyone to frolic in the waves and the damp sand below the point of the highest tide."
That doesn't stop the rich and famous from doing everything they can to obstruct access to this 27-mile strip of pristine beaches. Below, a few examples of their illegal handiwork. Read the rest
