Henrik 9-Sep-2011 [6303] | http://queue.acm.org/detail.cfm?id=2030258 An article on software liability laws. |
Reichart 9-Sep-2011 [6304] | Love it............and yeah, not going to happen. |
Geomol 10-Sep-2011 [6305x2] | It's just bits and bytes set in a certain way, and they can be changed anytime. From a philosophical viewpoint, there's something fundamental different between software and a house. |
Actually - from any viewpoint, I guess. | |
Pavel 10-Sep-2011 [6307] | red thread is rolling quickly so not to be overlooked: interresting toy for cheap: http://www.raspberrypi.org/ARM based 700MHz core 256MB RAM 100 Mb Lan 2 USB ports, SD card reader some (not exactly stated how many) GPIO, 1W power under full load, Quake3 and HD movie playing demonstrated. Linux supported from producer, but architecture not restricted to linux only. |
Maxim 10-Sep-2011 [6308] | could this be the project Carl is working on !? it is an embedded linux, its also more TV than computer since it supports only TV outputs. Carl's low memory using Amiga Exec Background would make him a prime candidate for working on this project which has to boot Linux and allow HD decoding within only 128 MB (os+gpu Shared) RAM . |
Henrik 10-Sep-2011 [6309] | It's not the project he's working on. |
Kaj 10-Sep-2011 [6310x2] | They're shipping Ubuntu |
The movie demos they did so far used their own player thingie. It's likely the standard Linux players won't cut it on Ubuntu in the provided memory | |
GrahamC 10-Sep-2011 [6312x2] | Hmm... POE would be nice |
Henrik .. wasn't Carl supposed to make some announcement of what he was doing .. or did I miss it? | |
Henrik 11-Sep-2011 [6314] | he was, but it didn't happen. |
Dockimbel 20-Sep-2011 [6315x2] | For Open Hardware followers: http://hardware.slashdot.org/story/11/09/19/1835250/Arduino-Goes-ARM |
I should be able to port Red on the Arduino Due (32-bit, 50KB of RAM) but the still low memory size might limit its usefulness. OTOH, Red/System should be able to work full power there. It should be fun to write a new OS for this platform using Red/System. | |
Reichart 22-Sep-2011 [6317] | It would be nice to have one of these types of little computers, which can shut down to some really low power use state, or even turn off, while passing power to something like a wrist watch level tech, which can react to some input (a dry contact, or a timer, or a signal from the internet in some form). Very power combination for many applications. |
Dockimbel 22-Sep-2011 [6318] | That should be doable, with the "wearable" version of Arduino boards (the Lilypad): http://www.arduino.cc/en/Main/ArduinoBoardLilyPad They are also some wrist watch level Arduino-based prototypes (often using an OLED display): http://www.google.fr/search?gcx=w&q=wrist+watch+arduino&um=1&ie=UTF-8&tbm=isch&source=og&sa=N&hl=fr&tab=wi&biw=1113&bih=1036 A few more very creative Arduino watches: http://hackaday.com/tag/watch/ There's even one you can already buy: http://www.getinpulse.com |
Henrik 22-Sep-2011 [6319] | will the ARM arduinos be available in the same form factors as the existing ones? |
Dockimbel 22-Sep-2011 [6320] | Here's a photo of the ARM-based new Arduino board: http://www.semageek.com/wp-content/uploads/2011/09/ArduinoDue.jpg I am not sure it will be available in tiny forms like the Lilypad or the Nano though. |
Reichart 22-Sep-2011 [6321] | Cool stuff, thanks for posting. |
Pavel 23-Sep-2011 [6322] | Arduino is already based on ARM in its NetDuino variant, Netduino is also in micro variant (breadboard based). |
GrahamC 23-Sep-2011 [6323] | Neutrino travels faster than light http://www.stuff.co.nz/world/5671848/Pillar-of-physics-challenged |
Sunanda 23-Sep-2011 [6324] | The theorists who know what that are talking about will have a lot of fun with that evidence, Graham. The rest of us can make things up -- like perhaps neutrinos are the only things that actually travel in a straight-line at a quantum level; photons take a longer path because they are bouncing around a bit. |
Ladislav 23-Sep-2011 [6325x2] | actually travel in a straight-line :-D (Instead of the Relativity theory, you prefer to destroy the Quantum mechanics?) |
Or I should ask: Alongside with the Relativity theory you would like to destroy the Quantum mechanics as well? | |
GrahamC 23-Sep-2011 [6327] | Experimental results have demonstrated that effects due to entanglement travel at least thousands of times faster than the speed of light |
Ladislav 23-Sep-2011 [6328] | travel at least thousands of times faster than the speed of light - except for the fact, that they actually don't "travel" |
GrahamC 23-Sep-2011 [6329x2] | No, just teleport! |
though if you have entangled pair, and you determine the spin direction of one pair, then the spin of the other is then set. But .. the knowledge of the other spin is only known at the site where the first determination was made, and that information can not travel to the other site faster than light so perhaps the limit applies to that information? | |
Sunanda 23-Sep-2011 [6331] | Right -- it's similar to Ly Tin Weedle's proposed method of instantaneous information transfer by modulated torture of a small monarch: http://www.discworldmonthly.co.uk/tpquote.php?qn=353&mode=goto |
GrahamC 23-Sep-2011 [6332] | New element discovered with atomic mass 312 http://www.appleseeds.org/governmentium.htm |
Endo 24-Sep-2011 [6333] | That's funny :))) "Governmentium", "These 312 particles are held together by a force called morons" :)))) |
Henrik 28-Sep-2011 [6334] | Sounds pretty interesting, but when will we see commercial deployment? Rossi is planning for October, this year, for his process. A Greek company is investing 200 million euros in the plant. An update on the E-CAT: The Greek company that was investing in this plant, mysteriously can't pay the money, so the 1 MW plant is now supposed to be installed in the US instead. Here are some pictures of the power plant: http://www.nyteknik.se/nyheter/energi_miljo/energi/article3264361.ece Another test was also conducted a couple of weeks ago, but it, like the other tests, did not show anything conclusively that the device really worked. It's highly suspicious. |
Pekr 28-Sep-2011 [6335] | What is that, another perpetuum-mobile like scam? :-) |
Henrik 28-Sep-2011 [6336] | Pekr, see this group on Apr-26 for a discussion about it. |
AdrianS 28-Sep-2011 [6337x2] | Actually, despite the rift between Rossi and Defkalion, it seems that Defkalion is still on track to show their own tech (Rossi derived, I guess) in the near term. They just re-opened their forums. |
and Rossi's own demo for October is still supposed to happen | |
GrahamC 28-Sep-2011 [6339] | Amazon announces crazy Kindle prices and their $199 tablet |
AdrianS 28-Sep-2011 [6340] | it bugs me that they forked Android (based on a version prior to 2.2) - that's a second strike. The first was that they bought Touchco, a very promising tech company which had one of the best and cheapest touchscreen implementations ($10/sq ft), good for both stylus and fingers. This should have been technology for the masses, not restricted to Amazon. Oh well, I guess it's still for the masses if they sell enough tablets with that tech, at some point. Forking Android though, screw them. With their user base, they have the potential to upset the Android cart. |
GrahamC 28-Sep-2011 [6341x2] | No worse than MS buying some technology for Windows ... |
Presumably it can be licensed | |
Gabriele 29-Sep-2011 [6343] | Amazon is cool but they seem to have the MS mentality of ignoring standards... "embrace and extend" i guess... |
GrahamC 29-Sep-2011 [6344] | If they can lower the barrier to entry ... then I'm all for this. |
Oldes 29-Sep-2011 [6345] | The problem with Amazon is it's "Amazon store developer agreement" - http://www.readwriteweb.com/mobile/2011/04/igda-updates-warning-to-amazon-appstore-developers-its-not-a-misunderstanding.php |
Pekr 29-Sep-2011 [6346] | Yet another mobile OS coming? http://www.osnews.com/comments/25196 ... I don't understand Samsung, as they have Bada. Also wondering, if HTC buys WebOS .... |
Henrik 30-Sep-2011 [6347] | If SpaceX can do what they show in this video, it looks promising: http://www.spacex.com/assets/video/spacex-rtls-green.mp4 |
Geomol 30-Sep-2011 [6348x3] | Looks cool. I'm wondering, why spacecrafts always have a smooth surface. Pinguins are known to have very little resistance, when they move through water, and they don't have a smooth surface because they used to have feathers. Sharks have a rough surface, I guess this also mean less resistance, when they move through water. A golf ball fly longer with all its little bulges, than if it had a smooth surface. Yet spacecrafts have smooth surfaces. |
*penguins* | |
About shark skin and swimsuits: http://www.curiocity.ca/everyday-science/sports/item/1001-sharks-in-the-pool.html | |
Henrik 30-Sep-2011 [6351] | It probably depends on how much is gained by improving airflow around the rocket body in relation to reducing its mass. |
