SMART boards are very nice hardware-wise, but their software is less than reliable. The service keeps stopping - we had to set up a login script that restarts it each session.
The Smarrtech ones are not simple IR sensors. I tried to duplicate their pens. IR cameras, yes - including a DSP processor. The patent outlines some of the maths involved in determining if pen or finger is poking at the board - the preprocessing part I can just about follow, but then it uses a neural network as a classifier.
I failed. I don't know how it identifies a pen from a finger - according to the patent it's on shape alone, but I tried both 3D printing and plaster-casting an exact replica without succeess, so I think there's another element I'm missing.
Those many different models are often just variations.
It's always fun trying to read a service diagram for Toshiba laptops. The diagram is of a hypthetical super-laptop that contains the intersection of all the components of the various models that use that chassis - it'll have a flash drive and an HD fitted in the same bay, two devices in one mini-PCIe slot, and so on. You open it up and find that the diagram shows three wifi antennas, but the model you are working on only has one. Screws are especially fun, as it'll sometimes show two screws going into one slot. You get use to it after a while.
I was drawing attention to MikeRT's obvious mistake (Assuming everything happens in the US) by providing an over-detailed account of why this renders his suggestion invalid.
Barrage balloons. String some blimps up on cables around the property, hang nets from the cables. It's legal, passive, safe - and only the most skilled of drone pilots could reliably navigate the maze without getting their rotors tangled. Plus the studio gets some free drones - somehow I don't imagine many of the pilots will be asking for their return.
It's pretty hard to legally buy a gun in the UK. You need a license, and they aren't available to just anyone who asks like in the US. You need to demonstrate a legitimate reason to own a gun (Self-defense doesn't count - pest control or organised sports shooting will do), and then there are some background checks to go through. There's even a requirement for a doctor's certificate of competence (ie, no mental illness) and a police inspection of the intended firearms storage area to ensure it is secure.
It's really quite good for annoying the gun-rights people in the US, because it's the type of totalitarian nightmare they fear - and it works. Our murder rate is a fraction of that in the US. Gun crime is exceedingly rare. We've not had a school shooting since 1996. The country is so safe, even our police don't carry guns - they have no need to, because they'll hardly ever encounter a criminal carrying one.
This is star wars, though.
"Eh... just tell the CGI guys to take it out later."
Not much of a bomb, then.
China tolerates NK, but their alliance is strained. They seek regional stability, while NK is always sabre-rattling at the south and at the world in general, provoking naval skirmishes as a show of force and generally stiring up trouble. You're right, it isn't worth the trouble - the cost of peacekeeping would be huge, and there would be diplomatic trouble with South Korea too. But I've no doubt China has invasion plans drawn up, and if NK ever does something that starts a real war, China will be ready to put a stop to it. They just won't be the ones to shoot first.
No need, really. Arabic numerals are also called Indian numerals, and predate Islam. They picked up the misleading name because they were introduced via Arabic texts.
They probably recruit engineers. Any idiot can be a militia fighter, but an engineer is a valuable asset to any terrorist organisation.
Fundamentalist Islam today looks very similar to medieval Christianity.
Muhammad raised an army, besieged and captured Mecca and went on to take over much of the surrounding area. He wasn't some hippy street-peacher like Jesus - he was a prophet of action, not just words. Given his willingness to use military force to convert rival tribes to his new religion, he may well have been perfectly ok with beheading those who effectively served the enemy by spreading goodwill and thus sapping his side of the will to fight.
I suspect it might be a translation issue. But to know that we need the oppinion of someone who speaks whatever language the announcement was in, presumably Arabic. Banning math makes no sense, but it might be perhaps banning certain types of math, or preparing for a yet-to-be-finished Islamic Mathematics cirriculum that downplays the role of western mathematicians.
Languages can be tricky. Another Islamist group, widely (Though unofficially) called Boko Haram, literally translates as 'Counterfeits are prohibited' - but it actually means something closer to 'Western education is unislamic.' A translation that wouldn't be at all obvious unless you are familiar with the region's history, and knew that 'Boko' might mean counterfeit or fake, but could also be a contraction for 'ilimin boko' or 'fake education' - a phrase used to describe British schools created when the country was formerly part of the British Empire.
Neither if which matters, because few believers actually do what their holy book says. They do what they want, then look to their holy book to justify it.
Nice idea, but not practical. This isn't an old-fashioned war of country v country. They'll just discard uniforms and blend into the civilian population. Unless you can justify vast numbers of civilian casulties, it'd be impossible to kill them all, and require a continued and expensive presence just to keep them underground.
