Re:Abolish Software Patents
This seems to be a patent on using hardware virtualization in sandboxing. In a 5 minute search, I found a couple of references to prior art, though it seems if Google's lawyers couldn't get this struck down, there may be something novel hidden in there somewhere.
With its 2011 copyright date, that ARM document appears to be 6 years too late to be prior art.
Claim 15 of https://www.google.com/patents/US20060031940 seems pretty descriptive and was filed in 2004.

Re:FTFY
Ahem. From the first document:
Dorhout has developed a robot he calls Prospero. Using game theory and swarm behavior algorithms, Dorhout predicts that future farming will be accomplished by swarms of Prosperos who will plant, tend and harvest crops by optimizing yield at every inch of a field. Prospero is an off-the-shelf, low-cost (about $8) robotic platform. Dorhout wrote an advanced walking program that enables Prospero to move in any direction, then added a sensor array, LEDs in its belly, a photo resistor, seed hopper and fertilizer sprayer apparatus and turned it loose.
Swarm behavior allows for optimized yields via more precise placement of seeds, better coverage of fields, and less wasted fertilizer and pesticide. How? By allowing a bunch of small, low-cost robots to parallelize a task that would otherwise require a multi-million dollar combine and harvester, which will spray hundreds of gallons of wasted fertilizer and pesticide all over the fields, and still end up with a sub-optimal seed placement & depth. Yep, no use in agriculture at all.
If you don't like the idea of swarms of robots self-assembling and adopting different shapes, here's a simpler example, which has actually been built, and uses swarm techniques:
http://www2.isr.uc.pt/~ali/MAR... -- from the paper:
The GUARDIANS robot swarm is designed to be deployed in a large warehouse in the event of a fire to assist fire fighters. The large size of the environment together with development of dense smoke that drastically reduces visibility, represent major challenges in search and rescue operations. We discuss a swarm of robots assisting a fire fighter. We explain the swarming algorithms which make the robots follow a human while no communication is required. Next we discuss our method for cooperative localization system which uses wireless network as a tool. We also discuss the interface between a human and the robot swarm. The swarming algorithms implement the functionality by which the robots react to the human. The robot swarm can provide guidance information. Together with the fire fighters we explored how to understand and benefit from a robot swarm. Finally the paper presents experimental results of our sensor based exploration method.
Tell the truth, you have not given any thought to the topic and just found something convenient in a week attempt to argue and look intelligent.
Back at ya, champ. Your inability to argue and, apparently, use Google, also makes me doubt the value of that "architect" title, too.

spherical moon
Curiously, I made a couple of years ago a moon map using the same NASA image as google, but projecting the map onto a sphere, You can find it in http://nautilus.fis.uc.pt/astro/ss/html-pt/terra/
l ua/globo.php. It's in portuguese, but I guess that you can find your way around. There are also other maps (like mars) if you are interested. -

Re:Don't forget the clock.
Useless? Not quite. The sextant was initially developed to more precisely calculate latitude.

Re:First-contact scenarios?Roman aqueducts built without modern engineering skill/techniques
Just because they weren't using modern structural engineering techniques, doesn't mean they didn't use engineering. They had math too, even though they didn't have the number "0".
Mayan calendars built without telescopes/calculus
One can observe the stars and determine the length of a year without using telescopes, by using other instraments, like the sextant or an equivelant device. Likewise, just because they didn't have calculus as we know it, doesn't mean they weren't able to use some form of mathamatics to calculate how many days there are in year.
In short: your statments are irrelievant.

Actually it varies
There's people out there looking at the Busy Beaver function who study the 4-tuple Turing Machine. And certainly it is possible to make a 3-tupple TM by further combining the 4-tuple operations. On the other hand, I think I've seen Turing Machines called 8-tupple by taking up a whole lot of extra space (I think they counted the two halt states or something).

Take GNUnet as an example...You must see that p2p is NOT all about file-sharing, and less yet about sharing copyrighted files...
Take GNUnet for example: an anonymous and encrypted network: the future. It's not even good for file-sharing (because it's slow) but people still want to use this network, it's development is growing wide and it's users too... GNUnet is a framework for secure peer-to-peer networking that does not use any centralized or otherwise trusted services. GNUnet is a p2p app, not a copyrighted-files-sharing-utility...
Don't mix all in one bag.

Re:Input devices are where it's at right now...The power of choice is needed, and goes far far further then all the article or this comments go... To give you an easy example, to the visual chalanged, the best Operating System is Micro$oft Windoze, and, hey, I completely hate Windoze... The question in all things is: what can -YOU- do about it, besides ranting? Easy... Picking, again, on the example of GUI's, if you think that GUI's should be standardized, you just have to simply choose what's the best GUI for you ATM and help it's development, make it the BEST GUI... and the choice is automaticly done. There are three major (realy good) GUI's, and the reaction to that by, for instance, Mandrake, was to include the three of them in their instalation... IF one day KDE and GNOME grow really really well and mark a great difference, Mandrake will probably include only those two, and most people will probably use one of those two... If you prefer, let's say, KDE, help them, help KDE to be THE BEST, reactions about that will do the rest... This is the power of choice, my friends, and people will tend to choose the best.

Ellips Rio Full
Multi source framegrabber if a maximum of two simultaneous colour sources or six simulaneous b&w sources and six channels maximum works for you go for the ellips rio full framegrabber. http://www.ellips.nl
They told me they were wanted to develop a linux driver but were unable to do so (it's a small company) and would happily assist anyone interested in developing it. Currently this guy is developing a linux driver that seems to have the basics running. The card itself is a wonderfull product and it seems to work flawlessly in all systems I've tried. -
