Why do I hear this crap from catholics all the time? They must teach it at seminary or something. Always referencing that same tired blog i might add. Depending on your def'n of science, the origins of the scientific method start with either the Greeks or the Arabs. Additionally, essentially the same methods were co-discovered by both the Asians and in India. Yes, some catholic priests moved humankind forward on a few topics, but it's not as if without them those areas would have languished long (see Darwin/Wallace for example). Given the damage the church caused in astronomy, I find it hard to believe the Catholic church has even had a net positive impact on science much less believe the church is responsible for it.
I don't always write GUIs, but when I do, I prefer wx.
But in all seriousness - I hate writing GUIs. I write embedded C for a living and am lost when it comes to the differences between window manager(s) on Linux or Windows or whatever. When I need to whip something up quick (and it's not embedded, and we're not going to sell it) sometimes I switch over to Python, and if that quick thing needs a GUI, wxPython (the port of wxWidgets from C to python) is something you can tack on there with minimum hassle. If you need a portion to be fast for your math calcs or whatever you can write that part in C.
There's a boatload of tutorials via google (and youTube).
1. Get 10 people together, everyone buy an iPad on the same day (maybe over 2 days).
2. Take the iPads home, remove iPads, replace with clay.
3. Return the iPads claiming you found clay in the box when you bought it.
4. Receive new iPads, sell on eBay.
Same net effect, 10 iPads. But this way you don't have to try and reseal the box in a convincing way, and you don't have to get the store clerk to take back a box of clay.
I have Ubuntu 11.04 or 11.10 (can't remember which) with Unity 2D running on an 8" touchscreen powered by a 800MHz Arm Cortex 8 with 512MB ram. The trick is to dump the 3d and get the 2d version. It's not blazing fast but it's certainly useable.
Doesn't this already exist as the beagleboard? Arm cortex A8 @ 1GHz, 512 MB RAM, USB host/OTG, DVI out, SD slot, Ethernet, RS232... It's not as small as a Rasberry Pi or a PCMCIA but it's still pretty small (about the size of a 3.5 inch floppy). Draws about 1/2 amp at 5V at full load. Can be powered off USB as long as it's own USB host is not used.
Lots of projects already going on it and it's open HW, schematics for everyone!
It's trivial to get one up and running with several flavors of Linux (I've been using Ubuntu). Plenty of other options as well.
IAANE -- 2nd law of thermodynamics. That Carnot will get you every time. The plants need to dump about 60-75% of heat produced to reduce entropy. For plants of this size that is a considerable amount of energy. Dumping to seawater, river or lake water is easy, cheap, and typically a non issue. I'm not sure there are any other solutions that are better than what they are doing now, even with the sea critters clogging the condensers.
Jellyfish clogging marine heat exchangers is a common problem at sea, but is of particular concern for US Naval vessels using nuclear propulsion. Typically the only fix is to open the exchanger and manually clean the stuff out. Some ships have a capability to flush with either low pressure steam or reverse flush with firemain water (although the firemain is now also likely to contain jellyfish). How these multi-billion dollar machines are designed without a method for removing dead jellyfish is beyond my comprehension.
So, to get much past O-3/O-4 in the military you need a masters in something. It doesn't matter what. Luckily, the various services offer correspondence courses so you don't ever have to enter a classroom....
All have watchdog timers on exceedingly short reset schedules AND the microcontrollers never load the program out of ROM...literally the only memory for the ECU is the registers. Controlling ignition advance and fuel duration is so basic it can be done on even the oldest versions of PIC and ATmel controllers. Put another way, if your car has a distributor and uses batch fuel injection...a 2 servo controller is no more complicated.
I think the simplicity of these engine control systems is what has kept this from already being common.
I had a Radio Shack 60 in 1 when I was 10. That thing changed my life! I literally played with it every day for years. Anecdotal evidence warning: I'm a electrical eng now. I don't think they are as straightforward now as they were back in the early 90s, regardless I have a 5 year old niece that will get one when she turns 9. Anyhow if you do go that route, RS also has a cheap book about basic electricity and electronics that is great for kids - the author's name is F. Mimms. It looks hand-written but it's super simple and has some circuits in it WITH explanations of how they work.
Also, science picture encyclopedias are pretty inexpensive.
Gold? Gold is so yesterday.
Minerals and vespene gas is what we should really be looking for up there.
Everyone knows you can't build any spacecraft without vespene gas!
Quick wikipedia search results in:
The longest stay in space was 438 days, by Russian Valeri Polyakov onboard Mir.
Separate search for time (one way) earth to mars is in the range 6 - 9 months.
The trip would require O2 production and CO2 scrubbers or some equivalent. The scrubbers used in industry and on submarines are generally toxic to people (and presumably to microbes) or get really hot. Either way I think the idea of cleansing the air to reduce illness would be trivial. Bring plenty of hand sanitizer and I think it'll be under control.
This isn't news...the Nuclear industry in the US has been using charcoal based on coconut shells to filter particulates for awhile. This news is literally decades old.
One other thing jumps out, according to the graphs teen pregnancy is slightly down, and education levels of mothers is slightly up! Both good things, even if it is an incredibly small margin...
So it may work on radiation sickness, which has to do with the effects of organ & blood cells malfunctioning. On the other hand the destruction of DNA is what leads to cancer from radiation and is really the much much bigger problem in related fields (such as medicine or nuclear power). So you may not get sick and die after absorbing 500 REM, but you're still going to be subject to a higher rate of cancer.
I was trying to explain this idea to my wife a few days ago, and couldn't get my point across...Although I am of the opinion that "the thing" is media when it is best for the publishers for it to be media, and it's the software license when it is best for them to be that. They've managed the best of both worlds at our expense.
What I want to know is how the end consumer ever bound by an EULA from the publisher? The publisher sold the game to Best Buy, and I bought it from them. I never got the game from EA or whoever. I highly doubt that best buy has agreed to 'license' the game so they can 'sub-license' it to me, and even if that was the case I would expect an agreement with the retailer, not the publisher.
Lastly, since they are cheating/stealing and other wise being shady I feel I am entitled to also. If they will get the best of both worlds so will I. Sure I'll buy a copy, and I'll feel free to rip it, give it to my friends, make backups, circumvent DRM, mount images, I'll do whatever I want with it short of keeping someone else from being able to play their copy (i.e. I won't buy then return to get a CD-Key).
I feel the same way about music. Those guys have been price fixing for decades. It's your civic duty to steal from them.
It's Nigeria...hire some local guy for $100 to kill the plaintiffs. Given the corruption, I'd bet OLPC could get away with it and they'd be ridding the world of these corrupt bastards in the process. Good for the kids, good for the poor local guy, good for Nigeria, and good for OLPC. Everybody wins.

With all the rabid budget cutting going on, we'll be lucky if NASA is still around in 2020.
Well, you have a very good point there.
