It still costs an arm and a leg (and sometimes an entire Antares rocket) to lift crews and cargo into space. So until we get around to building that space elevator we've always wanted, NASA will just have to use this drone-towed, pilot-less, rocket-launching glider.
Brazil was not bluffing last year, when it said that it would disconnect from the United States-controlled internet
According to a complaint filed by the FTC, JDI Dating and William Mark Thomas operate a worldwide dating service via 18 websites, including cupidswand.com, flirtcrowd.com and findmelove.com. The defendants offered a free plan that allowed users to set up a profile with personal information and photos. As soon as a new user set up a free profile, he or she began to receive messages that appeared to be from other members living nearby, expressing romantic interest or a desire to meet. However, users were unable to respond to these messages without upgrading to a paid membership. Membership plans cost from $10 to $30 per month, with subscriptions generally ranging from one to 12 months.It's actually somewhat surprising that they even indicated that the profiles were fake with that tiny VC logo. I would have expected that a company doing this sort of thing wouldn't have even bothered.
The messages were almost always from fake, computer-generated profiles – “Virtual Cupids” – created by the defendants, with photos and information designed to closely mimic the profiles of real people. A small “v” encircled by a “C” on the profile page was the only indication that the profiles were fake. Users were not likely to see – much less understand – this icon. The fake profiles and messages caused many users to upgrade to paid subscriptions.

Here's the trailer for Ex Machina, a sci-fi thriller about a young programmer selected to serve as the human component in a Turing Test on a robot. A really hot lady robot.
There’s a whole lot of interesting mechanics, optics, and electronics inside a Blu-ray drive, and [scanlime] a.k.a. [Micah Scott] thinks those bits can be reused for some interesting project. [Micah] is reverse engineering one of these drives, with the goal of turning it into a source of cheap, open source holograms and laser installations – something these devices were never meant to do. This means reverse engineering the 3 CPUs inside an external Blu-ray drive, making sense of the firmware, and making this drive do whatever [Micah] wants.
When the idea of reverse engineering a Blu-ray drive struck [Micah], she hopped on Amazon and found the most popular drive out there. It turns out, this is an excellent drive to reverse engineer – there are multiple firmware updates for this drive, an excellent source for the raw data that would be required to reverse engineer it.
[Micah]‘s first effort to reverse engineer the drive seems a little bit odd; she turned the firmware image into a black and white graphic. Figuring out exactly what’s happening in the firmware with that is a fool’s errand, but by looking at the pure black and pure white parts of the graphic, [Micah] was able guess where the bootloader was, and how the firmware image is segmented. In other parts of the code, [Micah] saw thing vertical lines she recognized as ARM code. In another section, thin horizontal black bands revealed code for an 8051. These lines are only a product of how each architecture accesses code, and really only something [Micah] recognizes from doing this a few times before.
The current state of the project is a backdoor that is able to upload new firmware to the drive. It’s in no way a complete project; only the memory for the ARM processor is running new code, and [Micah] still has no idea what’s going on inside some of the other chips. Still, it’s a start, and the beginning of an open source firmware for a Blu-ray drive.
While [Micah] want’s to use these Blu-ray drives for laser graffiti, there are a number of other slightly more useful reasons for the build. With a DVD drive, you can hold a red blood cell in suspension, or use the laser inside to make graphene. Video below.
