I had difficulty installing Win10 on two dual boot machines. Both machines would throw up error messages of one kind or anther. Finally on whim, I removed dual boot capability by disconnecting the GRUB2 drive from one machine making the Win 7 drive the boot drive. I was then able to upgrade to Win 10. The other computer had both Debian and Win 7 installed on the same drive. I needed to use a live boot CD to remove GRUB followed by a boot repair procedure to allow the Win 7 partition to boot. This allowed me to update to Win 10. I then had to use a live boot CD to reinstall GRUB. Ugh.
Now both computers are upgraded to Win 10 and are back to dual boot machines.
Anyone else have problems upgrading dual boot machines to Win 10? Microsoft should allow people to trade in Win 7/8 product keys for Win 10 keys, preferably through a website.
I learned that radiometers do NOT work by "light pressure" which was Crooke's, the inventor's, hypothesis. Radiometers do NOT spin in a perfect vacuum. The two mechanisms that explain why they spin were proposed by the likes of Einstein (relativity guy), Maxwell (equations guy), and Reynolds (number, not aluminum, guy).
Real question here-- I ask out of partial ignorance.
How is this different from say using light, a form of electromagnetic radiation? Everyone has seen a radiometer (the thing with the black and white vanes that spins when in light. My thought experiment is if you have a directional light source that is pointed at a radiometer, that will cause the radiometer to spin, i.e. impart a thrust on the radiometer. That means there must be an equal and opposite force imparted on the light source. I would imagine this would work in a vacuum-- it is light after all. Isn't this another example of electromagnetic radiation (light) giving thrust?
Looking at the linked video, I was amazed to see the number of surrounding cars and objects being tracked. Also looking at the video, you could tell for almost a second that the trailing car was going to be a problem. Perhaps self driving cars that realize they are going to be rear ended could blink/flash lights, blow a LOUD rear facing horn, or something to catch the attention of the trailing driver.
Putting a cell phone under tinfoil hat... 1) Phone in paraboloid reflecting dish. Better way to irradiate your brain. 2) Partial Faraday cage around cell phone. Less signal so phone increases transmit power. 3) Profit!
Given the endless stream of vulnerabilities and the treadmill of updating Flash, I decided to uninstall Flash. Given the hate that Adobe/Flash receives on Slashdot, I would imagine that a significant fraction of the Slashdot readership has uninstalled Flash (do you keep statistics on this?).
Can you please help the web move on from the failed experiment that was Flash?
Umm... Lets see. Fiorina's term as CEO ended in 2005. Hurd was CEO from 2005 till mid 2010. Apothekar takes over in mid 2010 and a year later Autonomy is acquired.
I'm no fan of Fiorina but it's a stretch to lay this on Fiorina. The acquisition was probably started under Hurd but Apothekar had a year to do due diligence and back out.
I think the biggest difference between a Rolex and an iWatch is obsolescence. A 50 year old Rolex is still a nice watch. A one year old iWatch (when the new version comes out) is an ugly paperweight.
What if we agree to spell out obscure acronyms the first time? Yes, I can google/bing it to find likely candidates, but what if you make life easier for all involved and actually use Border Gateway Protocol (BGP)? Mmmmkay?
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.
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!
Regarding pronunciation, I used to cringe/laugh every time Jobs said 'Jaguar.' It appears that there were three pronunciations depending on what you were referring to:

In a year or two, after the next version comes out, you won't want to wear this any more. Battery life won't matter. Problem solved.

Do I care?
Don't know.
Would I care?
Don't know.
Should I care?
Sounds like you should if you care about security/privacy. But since, I don't know what is going through your head, I don't know.
Could I care less?
Once again, don't know.
No strings but things still stick. You can't explain that!
Question: Are current FPGAs faster than 10-15 year old CPUs?
Umm, I think you have things backwards. For certain tasks, FPGAs are phenomenally faster than any general purpose CPU. The correct question should be:
Are current FPGAs faster than CPUs 10-15 years from now?
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.

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