Comment Re:This might have been incompetence, not malice (Score 1) 700

What they should have done is just set the PID to some generic USB CDC serial port so that the counterfeit chips would no longer use the FTDI driver and would no longer show ups as FTDI chips to the OS.

If after upgrading your drivers, your device no longer works, I don't think most users would make the distinction between PID set to 0 vs set to something else. Not working, bricking, de-functionalized, unrecognized by the driver, etc are rather fine distinctions. It either works the way it did or it doesn't.

Yes, I guess there is a spectrum of implementations of retina-like processing. On one side, there is the retina and on the other side, a digital camera followed by Photoshop. This is being done algorithmically in FPGA so is closer to the Photoshop end of the spectrum.

There are silicon models of retinal processing. See
http://authors.library.caltech...
And there is a book by Carver Mead (I think he was the thesis advisor for above dissertation) called "Analog VLSI and Neural Systems" with a chapter on in silico retinal processing. This is what I would call an artificial retina.

What they made at CERN would more honestly be called a real-time FPGA implementation of retina-like processing. The length of the wires have little to do with it.

Comment Summary is completely misleading (Score 2) 60

Reading the abstract, it is clear that what they did was to do image analysis using an algorithm (albeit in FPGA) modeled on what happens in the retina. Other than the speed advantage, there is nothing special about this that makes it an artificial retina. If you take a picture with a cellphone and do edge detection using software, is that an artificial retina? I would argue no more or less than what is described here.

TFS makes it sound like the image detectors are actually doing edge detection like the retina. The image sensors (CCD or CMOS or whatever) is doing no such thing. The image sensors are providing raw images that are being analyzed using edge detection algorithms using an FPGA.

There are VLSI implementations of retina-like processing, i.e. center excite, surround inhibit, that can do edge detection/enhancement, but this ain't it.

Jame's Clerk Maxwell (yes, the same one with the equations) figured out that the ring's of saturn must be made up of small particles. He came to this conclusion because a solid ring would have an unstable orbit and any disturbance would cause it to crash into Saturn. A fluid ring would form blobs and waves. Since neither of these happened, Maxwell concluded that the rings must be made up of small particles in orbit around Saturn. Bonus, he figured this out in 1856!

Sort of amazing what the human mind is capable of. On the other hand, we have the kind that make the comments seen above.

The Lovelace Test Is Better Than the Turing Test At Detecting AI 285

meghan elizabeth writes If the Turing Test can be fooled by common trickery, it's time to consider we need a new standard. The Lovelace Test is designed to be more rigorous, testing for true machine cognition. An intelligent computer passes the Lovelace Test only if it originates a "program" that it was not engineered to produce. The new program—it could be an idea, a novel, a piece of music, anything—can't be a hardware fluke. The machine's designers must not be able to explain how their original code led to this new program. In short, to pass the Lovelace Test a computer has to create something original, all by itself.

After enough scams like this, "kickstarter" might become the punchline to a joke. Sort of like April fools, but good year round.
