So the next revolution in space exploration would have to tackle the data problem; optical or near-optical lasers for transmitters and standard photosensors (CCD) for receivers. It is technically possible to use off-the-shelf components, the remaining difficulty being the beam aiming system.
A Turing-complete language is capable of functionally expressing a Turing machine. That is, given the theoretical construct, can the language encode it? An equivalent framework is lambda calculus. Any Turing machine can be expressed as lambda-expressions and vice-versa.
The physical world analog to the Turing machine is the Universal Constructor, a machine that can construct a duplicate of itself or a functional analog of any other machine that can duplicate itself, given enough time and raw materials.
These concepts are relevant because it's not clear if there is a class of problems not solvable by Turing machines (but solvable by another class of machines). As far as we know, human beings themselves are Turing machines (and constructors) and nothing more.
In short, private Japanese individuals would no longer be allowed to send packages over 1 pound to the US.
Likewise, the leaderboard only contains pre-ascended individuals (Paul Graham has a higher karma, but is not listed). From the listing we may assume the ascendancy limit lies somewhere in the vicinity of 50K karma.
Aside from that, did they also make the cars biodegradable? How about natural, locally-produced, hand-grown(hand-mined?) materials?
Also, a link to the particular strip: http://xkcd.com/827/
Also, where is Snowcrash? It surely belongs in that list.
Maybe the blokes themselves are paying to have their privates shown?
So what's the site's business model?
ON ERROR RESUME NEXT
Armed with only the help file (no manual), coding felt easy. "An error, you say? Just skip and pretend it never happened"Julian Assage's demeanor or persona is irrelevant.
