Comment Re:Open Source Model? (Score 2) 20

You can run it just fine if you have enough RAM. In this case that would be a 256 GiB system, of witch 231 GiB will be used to run the model. You don't need a GPU, but you need fast memory. ollama generates about one token (1 word +/-) for each time is scans the entire model's memory. It's more bound to memory performance than to CPU / GPU performance. GPUs have much faster memory, but less memory typically, but server processors with fast DDR5 and 8 or 12 channels should work just fine also. For smaller models you need less RAM, of course. There are 40 GiB and 4.7 GiB versions which you can run on your laptop quite easily, if you have 64 GiB or even 8 GiB RAM.

Comment Re:India does it already (Score 4, Informative) 95

Portugal does it already also, since two years ago. ID card, Driving License, and a few other documents, in a Android/IOS app. The app also generates QR codes traceable to a government online service so that another user of the app can verify the authenticity of the document in a centralized fashion, so it's basically impossible to falsify the document.

Comment How to solve those issues once and for all (Score 2) 227

I solved those issues long ago by behaving in the same way for all social circles. I've set for myself what I think are acceptable and honorable behavior patterns and abide by them always. Take it, or just leave me alone, it's that simple. That includes my friends, co-workers, parents, and just about anyone I know. It means I have to restrict myself a bit, but it also means I'm essentially a better person.

PS: yes, some persons don't like it, but they are a tiny minority.

Comment Not too many pixels in fact. (Score 5, Informative) 204

Actually since this is a near diffraction limited lens working at f/2.4 the spot size is going to be about 0.56um * 2.4 ~ 1.344um on the focal plane. The cycle size is about double, or 2.688um.

Considering it uses a Bayer array, and the pixels are spaced at 1.4um, the green pixels will be spaced at 2um (minimum distance to next green pixel). To properly sample you need at least 2 pixels per cycle (said Mr. Nyquist), but since pixels are not exactly points (they have an area) astronomers working in diffraction limited imaging advise 3x sampling in practice.

What this means is you would need a pixel size of 2.688/3/sqrt(2) ~ 0.63um (or 0.9um if using a Foven-style sensor) to properly sample this lens. 1.4um vastly undersamples the lens, as can be seen near the central area in the available samples: they are razor sharp in the central area, and otherwise are limited by aberrations.

A practical article describing this, with example images, can be seen here:

Aussie Scientists Find Coconut-Carrying Octopus 205

An anonymous reader writes with this excerpt from an AP report: "Australian scientists have discovered an octopus in Indonesia that collects coconut shells for shelter — unusually sophisticated behavior that the researchers believe is the first evidence of tool use in an invertebrate animal. The scientists filmed the veined octopus, Amphioctopus marginatus, selecting halved coconut shells from the sea floor, emptying them out, carrying them under their bodies up to 65 feet (20 meters), and assembling two shells together to make a spherical hiding spot. ... 'I was gobsmacked,' said Finn, a research biologist at the museum who specializes in cephalopods. 'I mean, I've seen a lot of octopuses hiding in shells, but I've never seen one that grabs it up and jogs across the sea floor. I was trying hard not to laugh.'"

US Air Force Buying Another 2,200 PS3s 144

bleedingpegasus sends word that the US Air Force will be grabbing up 2,200 new PlayStation 3 consoles for research into supercomputing. They already have a cluster made from 336 of the old-style (non-Slim) consoles, which they've used for a variety of purposes, including "processing multiple radar images into higher resolution composite images (known as synthetic aperture radar image formation), high-def video processing, and 'neuromorphic computing.'" According to the Justification Review Document (DOC), "Once the hardware configuration is implemented, software code will be developed in-house for cluster implementation utilizing a Linux-based operating software."

Comment The specification may be buggy in itself... (Score 1) 517

In the few programs I've made that had to be secure, by all means, bugs in the specification were found, years later, that allowed system compromise. Assumptions were made about other systems (that allowed us to authenticate users, validate user-classes, etc) that were false under some circumstances, for example, making a break-in possible even if the core itself was not buggy in itself. It would, essentially, maintain it's integrity but be fooled by others...

This is just like in cryptography: a secure algorithm does not guarantee whole system security.

Still a great achievement!

Ray Bradbury Loves Libraries, Hates the Internet 600

Hugh Pickens was one of several readers to let us know that, according to a NY Times story, the 89-year-old Ray Bradbury hates the Internet. But he loves libraries, and is helping raise $280,000 to keep libraries in Ventura County open. "Among Mr. Bradbury's passions, none burn quite as hot as his lifelong enthusiasm for halls of books. ... 'Libraries raised me,' Mr. Bradbury said. 'I don't believe in colleges and universities. I believe in libraries because most students don't have any money. When I graduated from high school, it was during the Depression and we had no money. I couldn't go to college, so I went to the library three days a week for 10 years.' ... The Internet? Don't get him started. 'The Internet is a big distraction,' Mr. Bradbury barked... 'Yahoo called me eight weeks ago,' he said, voice rising. 'They wanted to put a book of mine on Yahoo! You know what I told them? "To hell with you. To hell with you and to hell with the Internet." It's distracting. It's meaningless; it's not real. It's in the air somewhere.'"

Comment They are religious because they don't accept death (Score 1) 921

IMHO most persons are "religious" because they fear death to begin with and can't accept they are limited in space and time.

Non religious (does not mean atheists) guys tend to accept their condition and see death as perfectly natural and nothing special. they learned to live with it as part of their non-reliousity.
