Yes, alphas are stopped by foil. Do we know that foil would not gum up the works of a primary nuclear device stage? Sorry, that's TS and Born Secret https://en.wikipedia.org/wiki/... .
Forgot to mention, there's beta from the tritium which only has a 12.32 yr half-life https://en.wikipedia.org/wiki/... .
You can only replace the tritium so many times before seals fail and injectors break. The fissile material, Pu-239 and U-235, and the tamper material, U-238, although not highly radioactive, do emit alpha particles, which break electronics. Throwing alpha particles at high explosives and detonators also doesn't make them any more stable or effective.
Therefore, you either rebuild warheads constantly or find a design which is more immune to embrittlement and other alpha-related damage.

Whereas it was necessary to release 12 Ubuntu versions to keep up with the every-six-months releases of Ubuntu, for each of the Desktops, here's the track record of Debian based distros by Mint: six releases of Debian, three of those supporting multiple Desktops. So, Anonymous Coward, you seem to overlooked 83% of the Debian based releases of Mint.
2013.03.22: LMDE 201303 (MATE and Cinnamon) was released.
2012.04.24: LMDE 201204 (MATE/Cinnamon and Xfce) was released.
2011.09.16: LMDE 201109 (Gnome and Xfce) was released.
2011.04.06: LMDE 201104 Xfce was released.
2011.01.02: LMDE 201101 32-bit re-spin.
2010.12.24: LMDE 201012 was released.
I stand corrected, and confirm this http://en.wikipedia.org/wiki/Geosynchronous_orbit is the correct explanation. Therefore, each leg of the trip will be at least (longer depending on earth station distance from the equator) 119ms just for the transit, plus processing time, and if there are four legs, then it's at least 476ms plus processing time.
Thank you, GumphMaster.
Streaming: A guaranteed delivery style of service, billed by cumulative time of use. A terminal requests a context of X bandwidth (currently 8, 16, 32, 64, 128, or 256kbit/s) and, if there your current spot beam has enough resources available, you are allocated a guaranteed chunk of the available bandwidth. So if you ask for an 8k streaming context, you will at all times be able to send data at 8kbit/s.
Background: A best effort style of service, billed by volume. Each spot beam provides a certain amount of usable bandwidth. The bandwidth which is not in use by Streaming contexts is used for Background contexts. This means that the actual amount of bandwidth you receive with a background context will vary over time. The theoretical maximum bandwidth available is ~400kbit/s.
Clarke orbit is 22,236 miles above the center of the earth, not above the surface. Subtract the radius of the Earth (3,959 miles) and if he was on the equator at sea level, the distance from earth station to satellite would be 18,277 miles. That would result in a minimum transit time, each way, of 98ms. But, he's not equatorial, neither in Sud America nor Alaska, so I can't do the math without knowing LAT/LON.
Add to that the lag inherent in processing the signal, and it starts looking sick.
Was it truly lowest bidder? Anyone really check the procurement details? Or was the contract really let on the golf course? As a survivor of federal IT, I can speak to the wonders of golf course procurement by vendor-friendly management and what a mess it inevitably leads to for the poor schmos in IT who have to use the product and make it work.
No, for a Zompocalypse I'd stock up on.22LR, whereas I'd want.223 for a Flu Pandemic, for zombies need a head shot, whereas rapid fire would scare off the worried well as well as the infected who are transgressing on property rights.
Add a Hank Hill special with a regulator which dilutes the propane (since it has more energy per cubic) into Synthetic Natural Gas , and a manual valve to switch from one to the other for the once-in-a-century problem with the gas lines. Result, *surge-free* (grew up on the Gulf where 100 days a lightning a year fries a lot of electronics) electrical power from a fuel cell which also provides heat is a most excellent idea.
I had suspected that to be the case. Thank you for confirmation. Just quit a large, Romney-funded outsourcer of consumer device support who overwrote the user's HOSTS file at every boot. Just another verification that they were IT-clueless.

BritVids THREADS https://en.wikipedia.org/wiki/... and The War Game https://en.wikipedia.org/wiki/... are also adequately cautionary.

Downgrade it to 64bps, that's what it's set to now.
Maybe the gummint ain't interested, but Americans can and do - 73s and best regards de K7AAY.
Either an 8,500 euro transceiver http://www.cubesatshop.com/ind... or an SDR (Software Defined Radio) http://publik.tuwien.ac.at/fil... (or maybe the $18 receiver noted at http://sdr.osmocom.org/trac/wi... and http://hackaday.com/2012/06/27..., or a SoftRock TXRX http://fivedash.com/index.php?...), an upconverter/downconverter, dual circular polarized antennas, and an S-band broadband amp. See http://mdkenny.customer.netspa... for frequency specs. 73s and best regards, y'all, de K7AAY

Linux Mint already has multiple distros without Ubuntu (but Debian based). Therefore, Dcnjoe60 engages in fallacy.

The Guyanas, Suriname, Venezuela, Columbia, sure. República de Chile, República Oriental del Uruguay, República Argentina? Not so much
Congress _could_ help by throwing $$,$$$,$$$ at http://server-sky.com/ - no reason why servers have to be ground bound.

Yup. Do it all the time in the lab. No-brainer. Which lab, I'm not sayin'.

But they can shine a light through it and read it with a scanner. Use an opaque liner. Aluminum foil: It's not just for beanies any more.
Dang. Forgot to mention, it can run your cars, too. http://automobiles.honda.com/civic-natural-gas/
