Not sure about Egypt but the problem in Malaysia is that political parties have formed along ethnic lines. Because of this ethnic issues dominate political debate and issues which cross ethnic divisions don't get any visibility.
Yeah its been covered about a hundred times up the page. On the downside you won't have much control authority after you throw each rock. The large mass means that you would need a lot of energy to change its trajectory. Each rock would spend about two days falling to Earth and it would be easy to spot with radar. Almost immediately it would be possible to identify the city it was aimed at. A few hours from impact the impact location should be known to within a few or so. The best countermeasure might be to move humans and some other assets out of the way. A five metre rock (say 500 tonnes) at 11km/s okay thats going to make a crater smaller than Barringer Crater so lets say you get a 500 metre crater. Based on lunar experience the ejecta blanket will go out to 5km and it will be relatively safe at 10km from the impact point. So worst case is it hits the centre of Tokyo but the number of targets like that is limited. Seoul, London, Beijing, etc.
Brings to mind an early Heinliein idea: vacuum tubes could be built on the lunar surface using the existing airless environment. How about power amplifiers the size of electricity substations? How about turning rock into streams of alpha particles at all but a fraction of the speed of light?
Consider doing long baseline interferometry using optical telescopes at the lunar north and south poles and on the equator 90 degrees away. You could get a lot of resolution that way but the bad guys would know to be good when the moon was in the sky. Maybe lunar rock could be of use in high orbit though. Fire it to L1 and L2 with an induction catapult then bury your observation platforms in piles of rubble.
The moon enables you to dig in. Spy satellites in LEO can be destroyed easily. OTH there is only one Moon. Perhaps the military need to capture asteroids and place them in the L1 and L2 positions.
When I get an email from slashdot telling me that somebody has posted a reply I follow the link to the new post. But I don't actually see the reply. I have to click on a top level post and follow the tree downwards, clicking to open each post, to find the reply I want to read. So why can't slashdot directly show me the new message?
Similar to the problem to Malaysia then. Same party in power for decades but the main opposition are islamists and potentially a worse cure than the problem.
Currently I am paying 18.6 c/KWH (Australian dollars but very close to unity with USD at the moment). If I had to pay your rates I would definitely be going for it.
The system I am looking at uses the grid for storage. You feed excess power into the grid and get part of the value of the power back. But you don't get all of the value back and you have to pay for extra hardware to interface with the mains properly so I am also looking at cooking up my own system which will supply a little bit more than the power requirements of the house during the day and not bother with storage.
it appeared that part of an oxygen cylinder and its valve had entered the passenger cabin
Sounds like the tank itself failed, not the valve. Though as you and other posters point out, tanks are very reliable. Astronauts walking on the moon carried an emergency oxygen supply tank pressurised to 6000 psi.
avoid allowing ANY oil and high pressure air to com into contact (to avoid the accumulator turning into a very short lived one cycle/stroke diesel...)
Oh that brings back memories. We used to have an power station in the Melbourne CBD. Back in the day it run steam powered elevators all over the city. It had a big steam boiler which was shut down at the end of the day. They would let it cool then pump diesel into it to clean the gunk out. One day a bit of gunk was still hot and the diesel blew up. The tank was measured as being about a foot bigger in all three dimensions. They got an engineer out who scratched his head and suggested they fire it up to see how it went. It worked fine.
Aircon? Maybe he lives at the south pole. OTH solar powered aircon is just about the perfect solar power application. It doesn't need storage at all and the load scales perfectly with the supply.
I have been looking at PV cells for my house lately. Outlay after the subsidy from our state Government is such that the system would pay for itself in about five years. But if you factor in the opportunity cost of investing the money the payoff period is a lot longer.
The only way that can be made to work is for all of us to control the hardware and software we use, and for each of us to have a private key which we share with selected people. Systems which rely on dynamic key negotiation can be broken by routers. Systems which rely on globally available certificates can be broken by the authorities which operate the certs.
The ISP could still proxy the connection though. Proxy to FB and Proxy to client would still be encrypted but the proxy would get the username and password. The client may have to click through a warning about a mismatched certificate but I reckon most would.
Probably not even necessary. How hard would it be for the Tunisian government to get a CA in Tunisia to sign a fake Facebook cert? Then there'd be no warnings at all. I mean SSL only works if you trust every CA whose root cert is in your browser, and really, why the hell should anyone do that?
Good evening Mr By I represent the Government of Tunisia. A new future awaits you as an employee of the fastest growing security establishment in Africa...
The ISP can run a proxy which pretends to be the user from the point of view of facebook and pretends to be facebook from the point of view of the user. It can run an https connection to facebook and forward it to the user as a plain http connection. That way it can record or change anything in the facebook session and the user probably won't be aware that the proxy is there.
The proxy could also run an https connection between the proxy and the user but that is more difficult because encryption software in the browser would alert the user that the proxy is not facebook. However if the browser has been fiddled with its game over for the user on many levels. Lots of people in the third world access the internet from internet cafes. One place I used in Malaysia has a single windows image which is booted across the LAN when a workstation is started. If the Government got their own software on to the server with that image, or changed the template for all the internet cafes then it would be impossible to guarantee security.
True but say the user in Tunisia is using IE from Windows. Maybe the government looks the other way when people steal the version of windows with the "right" binaries. Or he's running firefox but Tunisia has a special localised version which you automatically get when you download it from one of their ISPs.

IIRC there was an episode of Get Smart were KAOS turns out to be run entirely by infiltrators from various organisations. Its such an old joke that you'd think police forces would take more care.
If its about that guy who was embedded in UK environmental organisations then I don't think he had to be having sex to be involved. Either that or I never got invited to the right demonstrations.

When Sun is between the Moon and the Earth.
Uh no.

You could equip your chunks of rock with simple heat shields. Not very difficult to do.

Why not Mars, as in Martes. The name says it all!
Good idea. Lets send the world's military to Mars, or better yet, Titan or Alpha Centauri!
You can get into lunar orbit with an engine smaller than the engine of a car.

This bit about QF30 is interesting

No citation sorry. Its an old old story.
How do you live without A/C?

I thought you were talking about a Coffman starter. That would be great on my van.
