Ion drives use electromagnetic fields to accelerate particles with an accelerator. Most times they use heavy atoms like xenon.
VASIMIR makes plasma from light elements like hydrogen and then use electromagnetic fields to heat the plasma... by controlling the temperature you can change the thrust/momentum the engine creates. (at least that's what I heared).

I don't know, because the I have yet to see a finished documentation about 802.11s.
Theoretically 802.11s is able to run OLSR. I think the node limit was introduced because the protocol should run on hardware (with VERY limited resources).
Another advantage of a layer 3 routing protocol is that it can be easily ported to multiple operation systems. Olsrd (as an example) is available on Linux, BSD, OSX (including a port to a hacked I-Phone) and Windows.

802.11s is designed for small mesh networks (I think the recent draft talks about a maximum of 32 nodes).
OLSR is used in much larger networks (at the moment 700+ nodes for the www.olsr.org implementation).
Get a secure server back at home... only carry a clean notebook without any important data.
When you got through customs, download the data through any kind of internet connection by using a VPN connection to the server back home. After this you can your customers data-center.
Don't forget to transmit the data back and wipe your notebook before you leave the country.
I'm not trolling, it's just that ZFS has been developed without the traditional and orthodox methods of disk-partition-filesystem and put everything on a single "layer", and instead of losing flexibility, we gain more, just because zfs developers were thinking outside the box (the now "traditional" way of doing things is segregation: the OSI layers, etc, claim to be more flexible, efficient and manageable than throwing everything together). I know, I know, veritas had this for years, so we could say that it was stole^H^H^H^H^Hcopied from them -- just as gates copied jobs, and jobs copied xerox.
Imagine the possibilities of breaking traditionalisms (like linux does "socially" but not "technologically"). Single layer designs do work well unless you have more than one file system. What's the use of a filesystem with built in LVM if you have a harddisk with multiple filesystems ?
The German museum which did the sending part of the whole project had to borrow a Lorenz SZ42 encryption engine from England (because the Allies grabbed all of them after WW2). The English GCHQ (http://www.gchq.gov.uk/) feared that someone would call it war booty (sp?) and a court might decide they don't get it back.
Same reason why the art taken by the Russians by the end of WW2 can never be shown outsite Russia... according to most countries laws they would have to confiscate it..
GIT is the sourcecode management system for the linux kernel and it has a number of advantages for you: - GIT use a SHA1 hash for checking the integrity of files, so you can be sure that you got the right file into your repository - a GIT "version tag" is a SHA1 has over the whole history of the repository. Noone will be able to change anything below the "version tag" without changing the hash - GIT supports signing checkins with PGP signatures, so it's clear who inserted new files into the archive.
Just burn the GIT repository on a CD or tape every week and keep the SHA1 hash tag for every day at a secure site on paper.

Germany is at 8.8% unemployment and we might hit 8% in a few years...
1.) cpu speed is a red red herring. Of course both C++ and java will be x times faster/slower on a machine with an x times faster/slower processor (if anything else stays the same).
2.) just look up the phrase "j2me" for java runtimes designed for embedded devices.
You will just get a "chicken-egg" problem with this argument, because it transform the problem "who deallocate my resource" to "who deallocate my class".
RAII helps to reduce the complexity of resource allocation because you can group them, but it doesn't solve the basic problem.
Would be interesting if this restriction of the licence is valid in Europe (or in England especially). In Germany we have something called "Allgemeine Geschäftsbedingungen" which limit the stuff a company can write into it's licences, maybe England has something similar.
See the video again...
you don't need ACLs in GIT because it's a "pull system".
Instead of giving someone access to "your repository" (let's say you are the coordinator of a large software project) YOU decide from which people you pull... you can do it based on a web of trust ("I know this guy, he produce good code !"), on corporate politics ("I only pull from the department chief programmers") or even on a case by case decission ("Damn, this smart guy from the user interface team explained me the bug in the network code and how he fixed it... I should have a look at this code.").
here in Germany there is an easy option.

It seems you have no idea what makes a good encryption standard today.
The only way to be sure that an encryption schema is good is to publish it so that thousands of scientists can look at it and search for problems. Better try to include the community into the developement process.

Another link you might like to read (just done some search on google):r k.html
http://www.idiom.com/~zilla/Computer/javaCbenchma
Of course you can create your own "dynamic" allocator in C++... but that doesn't make allocation/deallocation automatically faster.
Maybe you should search for some numbers to support your argument... just by stating "I don't buy it, C++ is still faster" it doesn't become reality.
If you still think Java/C# are slow, especially in terms of memory management you might want to read this:j tp09275.html
