If MtG is Turing Complete (and it is, see link below) that would imply there is theoretically no optimum strategy because you could have two turing machines playing an arbitrarily complicated program against each other and the only way to solve the halting problem is to run the game... correct or not?
Or maybe another way to phrase it is two Turing machines could play an unsolved / unsolvable problem, like maybe a hard AI algorithm, against each other using MtG cards?
Of course proving an unsolvable strategy exists is pretty far from proving a simpler solved strategy exists or not.
Whoops I forgot to explain why and only placed an imperial command, not sure how I got +5 unless you guys have ESP. The reason why is:
Weird design with known material = Success, mostly Known design with weird material = Success, mostly Weird design with weird material = Epic Fail, mostly
Figure out whats wrong with the design using "old fashioned" kevlar then once the design is all debugged whip out the magic threads and try a known good design with weird new material.
Single mode optical fiber is a waveguide already. Think about it...
I would have to think for awhile about the velocity of propagation. I think Vp would be higher for a hollow (vacuum) carbon nanotube optical fiber which might be an advantage.
I know its barely theoretically possible to make a hollow titanium sphere that is strong enough to hold a vacuum, barely, so it'll float, but not engineering practical to make it. I wonder if you could make a CNT tube that would float in the air. That would certainly reduce optical fiber costs, if you only needed a tower/pole at each end of the run, plus or minus wind forces I guess. If nothing else I think CNT optical fiber would be lighter than glass fiber, for aerospace or whatever. Pity its flammable.
Actually, in the Earth's crust, aluminum is more common than carbon by a factor of about 200. Only oxygen and silicon are more common. Source.
Talk to a chemEng about the nightmare of aluminium refining. Its not just that the hall process takes a lot of electricity mostly from burning coal, but it only works with alumina. You gotta run raw bauxite thru the Bayer process which is a whole nother PITA to pre-refine it before it hits the electrochemical cells as alumina. Most bauxite comes from Australia and Brazil, and there's only a "couple centuries worth" and then thats it for bauxite, so aside from recycling it'll be back to the old days before the Hall process where Aluminum was basically a precious metal. Aluminum really is a huge unholy pain in the ass to refine into usable metal.
Its kinda like nitrogen. Plants REALLY need nitrogen. But we all live in a great seemingly infinite pool of nitrogen gas, you say so whats the problem. Yeah but biochemically its a PITA to use N2 straight outta the air, so it (mostly) doesn't happen. Leading to all kinds of chemEng foolishness with ammonia and nitrogen fixing bacteria on legumes etc etc.
Having some atoms laying around doesn't mean they're convenient to use, or practical to use, or possible to use.
Make something that is politically correct in some parts of the world and you'll deeply offend other people in other parts of the world with different values.
We need MMOs with more of this stuff, not less. I'd much rather see the fighting online than in the real streets.
So when are they going to add a planet for rishrathra?
I believe they called that "second life". Something like a decade ago/. had a story on SL like every other day. I distinctly remember it was the "first" "major" game that required more than W98 it required W2000 or better which was highly unusual at that time. Then they banned everything everyone could remotely be offended by (cybersex, pr0n, gambling, basically everything that makes life worth living) leaving no one with any reason to go there anymore. Not sure if its even still up. Might check into it for laughs.
One thing I remember was it was pretty much the minecraft of the 00s. Wanna see a giant "life size" star trek enterprise? We gots one. Etc.
It was the kind of place where if you were not fascinated for at least 50 hours exploring, there was something wrong with your curiosity level, but after 50 or so hours it got kinda repetitive and boring, so...
I remember the funniest thing about SL was it banned real names, everyone had to use a psuedonym with a very short list of last name psudonyms. Lots of whining about that. I used "Turbo Pascal" because I wrote stuff on Borlands miracle ide back in the 80s on my first ibm pc xt (or was it the at clone?). Anyway I had a continuous stream of people coming up to me on SL and commenting "hey, I bet you don't know this, but there's was a compiler named after you". Yeah no kidding, that's exactly why I selected the name... so I stopped using that name. Oh well.
The "worst" part is you make a giant glass cockpit device and FAA/DOT/USCG/Area51 won't approve it for vehicular use, so you stick a battery in it and call it a tablet.
The first thing I thought of was Steve Jobs yacht or whomever it was, where the whole boat was run by computers. A waterproofed marine version would of course quintuple the price but would make a pretty awesome UI if you installed 3 or more in a boat (3 or more identical ones, so when you crack screen #2 you can bring the weather radar up on screen #7 instead or whatever)
Would make a great component for a project artemis bridge, too, if you can buy about six of them and mount them to plywood somehow.
It could be a lot less though, decrease the oxygen ppm by half and it can be 7 PSI, the pressure is not so important as maintaining the oxygen PPM as far as humans are concerned.
See apollo 1 fire. In orbit a 4 psi ppO2 fire is just a 4 psi ppO2 fire, doesn't matter much. But on the ground they like to pump that dude up to 4 psi over ambient to test for leaks before launch, especially hatch leaks. So you traditionally end up in 20 psi ppO2 and the slightest spark and "woosh" which is pretty much a summary of how everyone got killed in Apollo 1. Now sea level air means you have a ppO2 regulator so you leak test by pumping up to 20 psi absolute, of which most of the extra pressure will be mostly harmless N2.
I'm curious about the potential psychological impact of the module
You went off on a materials science tangent, I'm gonna go on the impact of "lets put him in the rubber room" jokes. "I heard the next supply ship has straitjackets". I suppose latex pr0n jokes too.
Nobody else mentioned vibration and oscillation? Not a huge problem if you're using as a passive warehouse but giant fans blowing life support air are going to make the thing kinda floppy all the time.
I think this would be an interesting science experiment, both the biology of "is a space sickness adjusted human vulnerable to wobbly walls" and the science experiment of repetitive strain failure modes of flex materials (the skin doesn't bend twice, once when made and once when inflated in space, it bends at say 1 Hz continuous while deployed if the structure wobbles. Also the economic experiment where if you have to go to expensive effort for vibration proof motors and all, vs the cost of just boosting a heavier traditional tin can.
There are also interesting impact and torque issues. So if you shove the middle of a wall with your shoulder (or worse) can it snap off an airlock 50 feet away, whereas unpressurized tin can would just bend?
yeah that would be 28 psi absolute, or 14 psi gauge. Unless you were testing it about 30 ft under water, which would probably be a great idea for leak detection.
Oh and another thing its infinitely more secure to encrypt the data before "putting it up on your homemade mirror network" rather than as a process.
For example, 99.99999999% of the data I "control" does not need to be encrypted. It just simply doesn't matter, even to a paranoid, although those know no rational limit....
Another example, lets say you were backing up a sql database of usernames/passwords for some site. The wrong way to do it is store the passwords in plain text and then encrypt the backup. Wrong for about a zillion (obvious?) reasons. If you have a decent system to hash and/or encrypt the data in the DB itself, thats much better, and no one can do anything with the encrypted data anyway. Or at least your database-level-backup script (as distinct from this project) can encrypt it for you (even if its just pipe mysqldump thru mcrypt and then into a file)
You'll find a userspace script solution to be infinitely simpler. A script that clones such and such directory onto such and such other directory while encrypting is simple, another script to clone that encrypted directory into some other directory (basically just rsync). Run it periodically outta crontab, etc.
90% your effort will be expended on error detection / correction / reporting, 9% of your effort on key management for the encryption and keeping the individual services up and running, and probably about 1% on the actual nuts and bolts of copying stuff around while possibly encrypting.
There are more failure modes than you'd think... consider giant files, for example, which don't fit. Or running it outta crontab and somehow having two copies running simultaneously. Or your scratch directory is on a device that suddenly got remounted RO instead of RW due to developing hardware issues.
Bidirectional sync is ambitious but possible. You'll burn a seemingly infinite amount of bandwidth trying it (think about the next quote for a second)
The basic idea would be to create one file per cloud used as a block device
Thankfully you're just mirroring instead of requesting some kind of raid-5 like technology. Also you're just dumping "a big ole backup file" rather than individual files.
I think the troll fail would be anything sent would just be/dev/null'd without him seeing it. So other than making FB rich, no point. "See that goofy kid? Lets make fun of him... I know, when he's at gym class we'll sneak a couple bucks into his wallet, I'm sure that'll be embarrassing" Fail.
IF your "receipt" for your $100 transaction would be a pic of him holding up a printout of your message or a guaranteed personalized response of some sort, then I'd start a fund to take donations to send him a goatse as a picture message or any other similar trollish pic. Or if it has to be text there's probably some fanfic pr0n text story or something like that.
One way to troll would be on the transmit side instead of receive. "Hey Mr National USA Politician, it cost me $100 to send you a text copy of the Constitution, clearly you have never read it and have no idea whats in it".
Digitizers draw very little power, and they interfere with image quality very little, if the difference is even perceptible.
I don't think logic and measurement have a purpose in a PR campaign. Look it draws "some" power and reduces visual quality by "some" amount. Therefore the "Platinum Executive Model" will be better because it doesn't have those performance robbing characteristics. They can even charge more money for the "better" executive model.
I suppose the/. equivalent of drinking a century (locally, that means 100 shots of beer in X length of time, where a weekend is not very impressive and an hour is pretty insane) is drinking a 0xFF hexadecimal.
The funniest is when you see yourself in the mirror (after taking a piss
Naw the funniest is when you're looking at a mirror after taking a piss and you suddenly realize you're not in a bathroom. You probably don't want to go into a bar/club where that won't get you thrown out.
First of all people are looking at this negatively. Given 3 women roughly all of the same 1-10 scale, you try to pick up the drunk one by finding the one with flashing red alert ice cubes first. Or going the other way, an ugly woman can find a cute guy with the highest intensity beer googles by looking for the ice cubes flashing red alert. Lastly college students are going to use "alerting ice cubes" for drinking games, not a preventative measure, like whom ever's ice cubes flash red first, wins!
Secondly, if you're feeling sober-ish and drinking at a bar and then suddenly pass out and wake up in some weirdo's bed or minus one kidney, the problem is not booze and the solution is not wiimotes in icecubes, the problem is someone paid the bartender to slip a pill in ur drink. I was hoping for an embedded EtOH sensor and/or a whole "GC on a chip" sensor unit, not a lame accelerometer.
Accelerometer to do "something" when thrown onto the ball game field by the drunk fan. Presumably seeing an enormous short term acceleration, correcting for any rotational accelerations, some camera interface could snap pick of perp. I believe drunks throwing bottles at ball game players was why stadia only sell (weak) beer in plastic cups now.
More likely both sides will try to hack the uC into some manner of proximity fuse for molotov cocktails.
could be perceived as having features that directors and executives have
Not having touch means much better picture quality and longer battery life... I could see the drones getting sore elbows from using the touch screen and having to stare at greasy fingerprints and shorter battery life, while the execs get a superior non-touch screen experience.
One killer feature touch phones have that touch monitors and touch laptops have is I rub my phone on my belly before using it to wipe off the top layer of grease. This scales up to tablet size. Not gonna work on a laptop / monitor or a big screen TV.
F look at that syntax error. Extra quote typo. See, you can tell I squirted that out in only a minute instead of giving it the 2 to 10 minutes it deserved. If it was perfect prose in that limited time, you'd know I cut and pasted that shit right outta Knuth.
Exactly. Its an honesty test. FizzBuzz is a stereotypical "do you know what a modulus is, the mod operator in your language of choice, some manner of "for loop and or incremental counter, and some basic logic and precedence rules in your language?" Since everyone thinks its brilliant after you do it a couple times it should be pretty quick, but something "similar level" thats actually new rather than what everyone else uses, should take 2 to 10 minutes. So give them one minute. Anyone who gets it perfect just googled and copy-pasted.
Debugging tests are much more fun. Redesign a system is much more fun. FizzBuzz is at least fast.
