Then clearly you don't comprehend what you are seeing when you see big 5gal buckets of sodium hypochlorate, or know that you can get a nice batch of hydrocyanic acid from controlled hermitic combustion of a bag of bloodmeal fertilizer.
Here's a hint. That 5 gal bucket of hypochlorate intended to kill the algae in your swimming pool can make a bomb big enough to blow a house into splinters. It is frequently used as an oxidizer in rocket fuel. Guess what, unless you go on a binge on buying the stuff, the checkout lady won't even look twice about you buying it! Make it into a bomb? Crush the shit up, blender it with some deisel fuel, and pour it into a sturdy container. Use a model rocket engine as the ignition source. One improvised explosive device, all ready to go.
Or, if you want a dangerous high explosive, you can go the more complicated route of putting ammonium nitrate into a bunch of 1 gal glass cider jugs, attaching some labgrade tubing to a glass shunt inserted into a stopcock, and putting aquarium bubbler stones on the other side, dropping some copper items into the cider jugs, corking them off, and using the resulting nitrogen oxide gasses to produce clean nitric acid with some distilled water. After that, you simply titrate out a nice supply of ETN explosive using the big bottle of truvia brand sweetener as the erythritol source. A 16oz bottle of truvia sweetener will get you one hell of a bomb.
For the above mentioned poison, you hermitically burn the bloodmeal without an oxygen source, and bubble the gas through a tall cylender of water. (Such as in a high temperature glass crucible). After that, the method of delivery is a subject best left for the madman; one I felt would be particularly nasty would be to add the hydrocyanic acid to some freshly milled mazipan, then chocolate coat it and hand it out. Marzipan already contains very small quantities of hydrocyanate from the bitter almonds used for flavoring, so it would be completely undetectable by the victim.
Remember, people who do this kind of thing premeditate. That means they plan, and make arrangements. These processes are dangerous, but not that difficult to do.
The same rationality behind banning firearms would also make you have to ban pool chlorination supplies and rose and lawncare fertilizers.
Don't make the mistake that just because somebody has gone off the deep end that they are dumb, and incapable of complicated premediation. There are plenty of homocidal geniuses out there, for whom such things would be child's play.
I am often confused, and more than just a little alarmed at the polarization that stories like this cause.
On one side, there are the people that would rather live in an Aldus Huxley novel than suffer the slight against their perceptions of safety that allowing the general public access to firearms presents. (Seriously. If there are 100 shootings per day, out of 250 million persons in the USA, your chances of being so shot on any given day are 4 places to the right of the decimal point in terms of percentages-- (borrowed possibly false statistic from previous poster.) At that rate, you are more likely to die in an airline catastrophe. Contemplate that when you advocate stampeeding over peoples rights because kids were involved.)
Then, on the other, you have the people that feel we are already deep inside an aldus huxley novel, and have a "freedom fighter" complex. (The types who wear the tinfoil, you know whom it is of which I speak.)
Where are the people like me, who live in the middle? The people who deplore the senseless death, but who blame a faulted cultue that stigmatizes people with mental health issues, makes care for such insanely unaffordable, and tries to pretend the problem isn't serious? The ones who understand that guns are simply a tool, and the purpose they serve in the hands of the public is a preventative measure against corruption in high places, and nothing more?
The solution to deaths like these is NOT "gun control".
The solution to deaths like this is to get people the help they so desperately need, without any overtones of disparagment, or of belittling the people who need that help.
Outlawing guns does NOT help the mentally ill get the help the need, before they snap and take others with them. It simply sweeps the issue under the rug, because outlawing the tool used for the killing is simply easier. Nevermind that any sense of security the measure brings is false, and endagers more innocent people. (If not a gun, then perhaps a bomb, or poison, or any number of other methods.)
I am tired of these stories. I am tired of the shield rattling. I am tired of the "Ra Ra Rah!" And gung-ho idiocy of both sides.
In cases like these, there are *ONLY* victims. There are no bad guys, unless you care to look in the mirror. Our blind complacency to the sufferings of others is what CAUSES this shit. Everything about this story is tradgedy. Stop looking for a fucking scapegoat.
Seriously. It confuses the fuck out of my why it always must be so, that we all lose our minds over this, and dive headfirst from the frypan into the fire.
Agreed, a straight flu is the most efficient design. However, the inability to close down a section of the exhaust conduit, and reroute exhaust from the primary reactor to secondary (or tertiary) failsafe exhaust ports in the event of a serious malfunction (like an asteroid impact, or even just a power coupling explosion. We *are* talking billions of joules of energy being distributed to produce to coherent planet killer beam here. A malfunction will be spectacular!) Or even just for maintenance without also shutting down the whole damned deathstar is just plain shitty engineering.
Likewise, due to the enormous costs of construction invested in the device, a means of quickly expelling all reactive materials from the core to prevent a runaway catastrophic failure is simply prudent. Anything that can generate enough energy during NORMAL operations to blow an earth sized planet apart going critical inside a star system with inhabited planets is going to make somebody's day quite miserable indeed! Ejecting the reactant to make it impossible to achieve a critical failure of that type prevents both catastrophes. It would also make a very powerful excape thrust to push the powered down station away from any gravitating bodies. (We are talking billlions of liters of deuterium or helium 3 to power something like that. Venting it *will* move the station.)
I understand that astroengineering isn't easy, but risk management is very poignant as a concern when building planet destroying super weapons.
Consider:
Rebels discover you are building said superweapon, and seek to blow it up by destabilizing the fueled up main reactor. The resulting explosion will send very high energy debris all over the system used for construction, essentially making the system useless for habitation, or for any further harboring, as it causes extinction level events all over the system in question from falling debris.
Rebels discover your completed superweapon as you move the behemoth around. (Seriously, do really didn't think that moving something the size of a moon around wasn't going to cause gravitational effects that could be measured LONG before you entered firing range of habitable worlds? For real!?) This gives them time to get sabboteurs aboard to steal technical data or worse, and you suffer the "2m exhaust port" failure...
OR...
In either of the above cases, the rebels ATTEMPT to light the main reactor using a cascading failure, only to have the cascade be intercepted by a safety interlock on the exhaust port, as reactant is simultaenously ejected to propel the station away from either the construction yards or target planetary system, and simply powers down primary power systems. Without main power, main engines won't come on, so the station becomes just another orbital mass. It would take emmense amounts of fuel to repower the main reactor, so if the rebels try to capture the station, it still won't be going anywhere, and your conventional assault fleet can mow them down. (Not to mention the hundreds of thousands of people you have already on the station to repel boarders.)
The first two result in a complete loss of investment, while the third permits salvage.
Hmmm.. let's think about that.
Yeah. Install the damned inerlocks and reactant purge emergency systems, OK?:D
Clearly your instructor was a slave to his own technological superstitions. Like any situation where you must sacrifice a useful commodity for a practical failsafe, the degree of sacrifice requires an in-depth analysis to find the optimal implementaton, for a given scenario.
It makes no conceivable sense to allocate 32gb of swap, on a file server serving several hundred people, running with 16gb of ram, for instance. Hell, having that much ram in the file server to begin with is questionable, unless the system is also doing full disk encryption, and thus also doing heavy math with each read/write that connected users perform. Regardless, if properly configured, memory load is NOT going to spike. 4gb of swap would probably be overkill.
The 2x Installed RAM paradigm is only for servers that are likely to suddenly gobble up RAM like it was popcorn at a ballgame. Things like climate modeling servers, shared university general purpose math servers, and the like.
Without knowing the intended function of the server, the answer would be impossible to answer. It could range from anything from ZERO, to "OMFG! GOBS and GOBS!"
Insistance that the answer is a stock, kneejerk value without accepting qualifying arguments simply tells me that your instructor is either a lazy fuck who doesn't want to think about the answers his students write in, is beholden to an antiquated paradigm of how things are done and what resources are available, or both.
I have 1gb of swap allocated on my linux box, for instance. Even running folding@home on all 8 cores, with "huge" dataset selected, it DOESN'T even touch it.
Given the weight on top, I find it hard to accept that they are air filled tires.
Since it doesn't go fast anyway, solid rubber tires, (or tires filled with an inert solid of some sort) would make much more sense.
In which case, a.22 round is only going to either get lodged in the tire, or bounce off. Simply because the tire is exposed doesn't mean the tire is air filled. (In fact, an air filled tire would be beyond the critical limit for sidewall pressure with that much improvised armor on top. They would pop.)
A cheap trick would be to fill the tires with dry, fine sand, THEN inflate to pressure. Doesn't solve the "guns make holes in the tires" problem, but also prevents the "hole in tire causes immediate immobility" and "tires suffering too much sidewall pressure" problems.
Again, such tires would NOT be capable of highway speeds. 20mph would be pushing it to the point of melting the tires. This is a heavy, gun carrying metal turd. It won't be driving that fast anyway.
If I am not selected, it won't hurt my feelings at all.
But I will certainly never go, if I don't apply, now will I?
As for speaking math, I speak it just fine. You are just suffering from extreme crainial rectumitus due to approaching a difficult problem from a preconceived point of view. (Hint: you can't be objective, if you have already judged.)
Hot jupiter on outer edge of habitable zone with small rocky moons resolves this problem.
Specifially for the moons.
The moons will tidelock with the gas giant, not the star. This gives the moons a defined day/night, and seasonal eclipses. Day and night would be long, depending on the orbit of the moon around the giant, but well defined.
Needs to be on the far outer edge of the habitable zone because of tidal heating.
As long as the statement isn't something seriously harmful, like "asbesto-brite! The SAFEST, all natural toothpaste on the market, now with even MORE of the microfiber asbestos you know and trust!"
Misleading and dangerous advertising should be a crime, but giving a rounded (within the actual rules of rounding numbers) tally of your userbase or consumption is just plain silly.
It shouldn't be government's job to make sre the day traders don't make stupid trades, and research their "leads" first.
Buying stock is a risk based venture; it should not come with a presumption of gains, nor with implications of full price refunds for investors with buyer's remorse.
When it comes to the stock market, Caveat Emptor should reign supreme. Let the buyer beware.
It is quite aparent you have never worked a day in your life doing any of those things. (Amusingly, they are things I have done.)
But to educate you further, coolant in an NC machine is pressurized. It sprays in jets to blast the chips away. You could operate one in ZERO gravity, as long as you also had a wet vac running in the machine envelope. (This is a commonly added option even! How do you think vacuum table fixtures work?) The tradjectories of the chips is moot. The envelope is closed, and coolant and chips spray all over inside even in earth gravity. The machines are designed to deal with that just like they are designed to deal with humidity and oil vapors.
But of course, imagine a totally fucked up and ramshackle operation with everyone sleeping on cots in the machine shop, with a unified pressurized habitat, because that would be such epic fail, it would fit perfectly with your internal monologue.
You have consistently resorted to personal attacks on my inteligence, made faulty assumptions about my work history and mental health, and have all around refused to admit any of the glaring faults in your arguments despite repeated attention being drawn to them.
But of course, because I misspell a word or two, I must be an illiterate yokel wo can't even tie his own shoes. Because, you know, actually evaluating that glaring nonsequitor would contradict your world view.
Go complain to somebody else, and be a sour, bitter, shriveled husk of a human being someplace else. I am sure there is no shortage of things you can go complain futilely and impotently about that don't concern you in any fashion about, like you did here.
Seriously. You complained about having to spend money on a non profit, contributions funded mars mission that won't cost you a dime, did so shamelessly, and attacked me and every other reader of slashdot with a shameless stereotype that does not represent reality in any fashion.
I will still apply on their roster, regardlesss of your misguided and erroneous points of view. Your argumentative and needlessly negative and acid candor have in no way discouraged the decision, and in fact, only demonstrated why people who CAN do things should sign up for this mission, and try to make a difference someplace else, away from frighted, sour, and small little people like yourself.
The idea here is to produce a "blurred" image by diffracting incoming light before it enters the cornea, that the eye then focuses with its internal lens. This is accomplished using the prismatic effects of "old school" LCD elements.
(Rememberr in the 90s whe color LCDs came out, with TFT displays? Remember how if you looked at them from an angle, all the colors were fucked up? That is because the color image was being created through prismatic diffraction.)
Combining several layers of these "prism" LCDs, along with some generalized raytracing on the part of the image processor, and the contact lenses would alter the incoming light such that a phantom image would be produced inside the eye, and appear as if it were a few feet in front of the user. Because the incident angle of the prism to the retina is fixed, the chromatic abberation would be fairly minimal, but some "pretty rainbow effects" would be unavoidable.
Much like a modern LCD has a prismatic layer before the LCD layer, you would need two LCD layers at least to get a reliable diffraction technology. The first layer selectively polarizes the incoming light, and the second layer selectively diffracts it to produce the "hologram illusion".
For lack of a better term, it would be a prismatic psycho-optometric display.
Some pretty sophisticated processing would be needed to generate the projected images though. The image would have to be generated out of focus on the corneal display layers, so the eye itself could bring it into focus. Otherwise it would never work.
Again, opaque images wouldn't be possible without completely diffracting the incoming light, and making you completely blind to the real world. Ghostly, and candy rainbow colored hologram like images would be about the best you could do.
Worse, remote attack induced epileptic seizure, caused by cycling the LCD at 25hz.
You think the annoy-a-tron, and the universal off button remote were power trips for angry nerds? Try having a bluetooth dongle that makes people have siezures.
Instead of displaying an image the traditional way, it could simply be used as a prismatic refractor to alter incoming light to produce the 'perception' of having a distant image.
Eg, your eye's muscles focus "far away", because that is where the image would resolve from the controlled refraction done inside the lens.
This would be comfortable, but images would never appear opaque. (Relies on bright ambient light, and defraction of incoming light. Shadowy, shimmery outlines with candy pastel colors would be about the best you could do without completely obliterating the light patterns entering the prism, and blinding the subject to the real world.)
This would need multiple layers of LCD prism to make work though.
about the best this could be useful as, is as a flash protection optical device. Couple a thin film photocell to the LCD layer, so that a bright light automatically powers the LCD and dims the light that reaches the eye. That way it wouldn't need all that data bus hanging off of it.
For an image display? Useless. The focal distance is way too close for the human eye. The resolution sucks balls. Displaying an image would require a data bus, and I don't want that crap irritating my eyeballs by hanging out plastic ribbon cables.
For welding goggles? Kick ass! Protecting soldiers from flash burned retinas? Kick ass! Displaying swirlies on your eyeballs as a conversation piece? Dude, you have ribbon cables hanging out of your eyes.
Augmented reality? What the fuck are you smoking? I want some.
This is a NON PROFIT venture, funded by CONTRIBUTIONS.
Know what that means dickweed? It means it doesn't cost YOU a dime, unless you donate!
Complain about paying for it some more, asshole.
As for living in a tincan with 15 other people? I really wouldn't mind. Seriously. I am ambivalent about human company. They could be stark, egregious exhibitionists that fuck goats right next to me and I wouldn't care.
Also, my disdain for YOU does not mean I hae disdain for all people in general like that.
Also, your insistance that mars has "zero or low gravity" betrays your insane ignorance.
The 6 month trip to mars is just that. The trip there. The colony is not an orbital one. It is to go on the martian surface.
Mars has metal ore deposits. That is where said blacksmith gets raw materials.
The colony needs to extract mineral oxygen to suppliment its supply, and that is already a fair portion of the refinery aparatus for metals right there, if efficiently designed. YOU GET METALS BY REFINING MINERALS FOR AIR, fucking idiot. It is a fucking biproduct!
Mars has a surface gravity of.38G. NC machines are built "heavy" to supress vibrations, not because they need to weigh 20 tons. Being 1/3 earth weight does not reduce their inertial properties. A 20 ton NC machine takes just as much energy to push on earth as it does on mars. It only makes it easier for a crane to move it into the machine shop as the shop is being built. Most NC fabrication tooling mechanically holds the stock material with vices and fixtures. Gravity is unimportant to any of that. Gravity only comes into play in removing chips from the workpiece, and controlling coolant. Mars DOES have gravity. Chips will fall away, and coolant will flood just fine.
Gasses produced by NC mills are not that dangerous. Mostly water vapor, and volatized lubricating oil. Also, NC machines can be designed to use compressed CO2 as coolant. There is a copious supply outside. It can be safely vented right back outside. CO2 coolant is especially commonplace for aluminum and magnesium milling.
Clearly, I know *a lot* more about this than you do. Insisting I have no idea what I am talking about after I have consistently poked holes in your arguments like this does not improve your position.
It must be sublime, lieing to yourself that you know everything every day.
A mars colony would have to establish on the ground manufacuturing almost immediately. It would need it for the raw materials you speak of, like oh... oxygen and water.
The martian soil is heavily loaded with iron oxide. That is why it is fucking called "the red planet." Processing the soil would be necessary to do pretty much *anything* with it, given that it is contaminated with perchlorates, and other salts that render it unsuitable for agriculture, even inside a habitat.
How's this for you:
You collect the dirt along with dry ice and frozen water ice from the subsoil. It is contaminated with perchlorates. You bring the dirty ice to the colony site, and process it this way:
1) heat it to 500F, to liberate all the water and chemically bound oxygen. Run this through a gas fractioning system. This gives you pure CO2, O2, and water. How you heat it is not important. Big assed mirrors would work if you can keep the dust off. Most likely a small fission powerplant would be used though, and the heat would be pumped into the living quarters to keep it habitable.
2) return some of the sequestered water to the soil sample to dissolve the salts present. Extract the saline water, and distill it. This gives you calcium, sodium, potassium and other alkali earth chlorine and sulfate salts, and reclaims the water again.
3) vibration segregate the soil. This seperates metalic ores from less useful silicates.
4) use the silicates to manufacture glass for solar collection, mirrors, fiberoptic cable, and fiberglass insulation. What isn't useful for glass, is used as subsoil in agricultural habitats.
5) chemically isolate the salts from process 2. Process them into essential inorganic strong acids needed for any useful petrochemical operation. (Phosphoric acid, sulfuric acid, hydrochloric acid, and pals.) Treat the metal oxides with strong acid cocktails, to get transition metal salts. These have uses in everything from agricultural fertilizers, to feedstock for metal refinement. The high CO2 atmosphere of mars would make it very useful for producing concentrated cabolic acid to fascilitate these conversions.
6) mars has depleted its atmospheric free O2 reserve almost completely. Subsoil iron, copper, tin, and other valuable structural metal ores *will* be present. Clearing the surface soil for the perchlorates and other raw materials will expose bedrock where these minerals are found. This is what you refine into feedstock for additional fabrication systems and habitats.
So, things the marsian colony will need include:
A nuclear fission plant A gas fractioning system An industrial electric kiln + glass furnace An industrial induction heater and metal foundry crucibles An industrial wet chemistry complex Human habitat structures (includes water treatment and all that) Heavy earth movers and mining equipment A dedicated machine shop to maintain the earth movers and mining equipment Agricultural habitats Recreational structures
The NC machining systems would be inside the machine shop, and would be mission critical equipment.
What you seem to fail at understanding, is that simply because the air outside is lethal, that does not mean local material harvesting is impossible, or undesirable.
As for being an idiot, all you have to do is read the primers for this mission to know that using native materials is EXACTLY the proposed mission for this colony mission.
That means they will NEED people like me.
That you don't like that fact, or think the mission is doomed to failure doesn't ammount to shit. It just means you shouldn't go.
Indeed. There is nothing to be done about china being stupid with regard to the internet, and that is as it should be. The free internet will just ignore china.
However, any appeals made by OUR congress critters concerning "free, open, decentralized control" is really just doubletalk for "controlled by our hedgemony of media and telecom interests, with no oversight."
Really, "free and decentralized", in regard to the way the internet was concieved, is that there is no distincton between clients and servers, and that ISPs are mere dumb pipes.
That is *NOT* what these lieing dirtbags have in mind.
What you really mean is that US politicians unanimously voted that they should have absolute control over enacting draconian restrictions on the global internet, and that those "european commies" should have any say involving red blooded american technologies and interests, and that the rhetoric about bottom up, decentralized administration is merely a red herring to keep those watchdogs distracted while they aid the henhouse.
(Spasm)
Sorry. I don't know what came over me there. Have you seen Aldus Huxley anywhere? I think I need my daily opiate injection...
What are you talking about? Many engineering students make modifications to vehicles, purely for pleasure.
The issue is simple:
If I WANT to tinker, *I CAN*.
THAT is the freedom being discussed here. I can't just decide one day that I am dissastisfied with the windows file copy dialog box's estimated time to completion algorithm, bust open the source code, and tinker on it.
I *CAN* do that on linux. (Moreover, if my reimplemetation is superior, the linux community eagerly wants my changes!)
If I *want* to modify my fuel injection system on my vehicle, I can. The hood isn't welded shut, and the ECM isn't designed to kill itself when tampered with. Compare that with say, an xbox360 with efuses, and tamper tape.
Stallman is definately a crackpot in a large number of ways. (Harvesting fresh footfungus in front of an audience and all that..) however, arguing about this level of freedom, even if people choose not to make use of that freedom, is definately to the betterment of mankind, and should be supported.
Also, just so you know, turning out a screw on an NC lathe takes all of about 5 minutes.
Unlike the fantasy world you live in, I actually work in a production environment. I know what you will need to have a successful colony startup.
You approach it from the standpoint that it will always fail. That is why you do not see the value in someone like me going. (You are a selfish whore, who wants me to stay here and design pretty toys for YOU to consume, here on earth instead.) Newsflash. I don't want to work for you.
Tell that to apollo 13 astronauts. The ones who had to shove a square peg into a round hole to have breathable air. Shit happens. Having an engineer on board the mission is vital, especially one who can make creative fixes. It takes 6 months at least to get a shipment from the earth to mars. A colony simply can't wait that long, nor could apollo 13 wait for mission control to shoot up a replacement co2 scrubber. They were damned lucky they were in close orbit of earth, and had near realtime communication with ground team engineers. Otherwise they would have died up there.
Mars has several MINUTES of com latency with earth. Calling tech support on earth is NOT a viable option, wiseass.
Your whole argument can be lampooned like this:
"You are a blacksmith, and your anvil and hammer take up too much room in the cargo hold, and take up weight that can be used for food! We don't need you in the new word, we can send ships back to england to get all our horses shoed, get nails, and fix our plows!"
In short, you are an idiot, and don't have the slightest clue what you are talking about.
I have this nasty habbit of watching the behavior of other people, and am very interested in how stereotypes develop, how they relate to group demographics, and how they also fail to describe individual people.
I have had the great (mis)fortune of being able to observe "important" people in many niches, and levels of "importance", and have come up with some general rules of thumb concerning their behaviors. These are stereotypes, of course, and should not be seen as gospel, or as describing individuals.
That said, the stereotypical "important person" (I keep using that phrase, because it covers a large demographic ranging from senior managment to politicians, to police officers.) Is actually very insecure about their position. They have worked very hard to get into their "important" position, and are terrified of being displaced, either through their superiors replacing them with a better employee, or through discovery of their being a crook.
This insecurity makes this stereotypical person very paranoid, and prone to establishing elaborate plans and collusions to prevent the possibility of competition for their position. It also makes them very susceptible to "terror", and they react very agitatedly and aggressively toward any 'percievied' threat.
A good example of this comes from a friend of mine who works with/near city government of his small town. Shortly after the sept 11 tradecenter attack, this small city government (under 100,000 residents) "increased security", was actively looking for terrorists, and had a major panic attack when a passing pedestrian left a backpack in the lobby while sad pedestrian used the public bathroom. (For real, they thought he was a bomber.) The recognition that they were simply not that important to attract the attention of organized terror agencies simply didn't kick in even once.
Due to this hysterical paranoia, they seek any and all means to "feel safe", which means they have absolutely no mental barriers against locking innocent people into padded rooms for discussing "scary" topics, or even just discussing the shortcomings of our stereotypical "important" people.
We can see manifestations of this in the US government, where serious discussions of enacting "indefinate detention" without a trial, or oversight "for national security" took place not all that long ago, and was narrowly struck down.
Being told that the measures that make them feel the most secure, are demonstrably the worst measures they could ever attempt when wanting to actually BE secure, will usually make them confrontational, and increasingly paranoid. They have an uncanny tendency to have a superiority complex, that prevents them from accepting professional advice, if that advice goes against what they believe. They view such offers of policy advice as attacks against their credibility and viability as leaders, and not as the healthy, helpful professional advice that it is. In order to get them to enact outside advice of this nature, they have to be duped into thinking it was their idea first.
That has not occured with this study. This study directly contradicts the currently held practices of important world leaders in dealing with people discussing "dangerous and scary" things, and will be viewed with derision, and outright contempt, (and more than a healthy dose of fear.)
It will be mocked and ridiculed behind closed doors, completely ignored in public commentary and the press (unless the press brings it up, then expect diversionary tactics), and burried. The researchers themselves might even experience difficulties getting more grant money, though the cockblock will be subtle.
In short, don't expect this study to bring enlightenment in our leaders.

I am tired of these stories. I am tired of the shield rattling. I am tired of the "Ra Ra Rah!" And gung-ho idiocy of both sides.
In cases like these, there are *ONLY* victims. There are no bad guys, unless you care to look in the mirror. Our blind complacency to the sufferings of others is what CAUSES this shit. Everything about this story is tradgedy. Stop looking for a fucking scapegoat.
Seriously. It confuses the fuck out of my why it always must be so, that we all lose our minds over this, and dive headfirst from the frypan into the fire.
We like to pretend that we have sharp minds.
For FSM's sake, fucking use them.
Re: straight exaust port.
Agreed, a straight flu is the most efficient design. However, the inability to close down a section of the exhaust conduit, and reroute exhaust from the primary reactor to secondary (or tertiary) failsafe exhaust ports in the event of a serious malfunction (like an asteroid impact, or even just a power coupling explosion. We *are* talking billions of joules of energy being distributed to produce to coherent planet killer beam here. A malfunction will be spectacular!) Or even just for maintenance without also shutting down the whole damned deathstar is just plain shitty engineering.
Likewise, due to the enormous costs of construction invested in the device, a means of quickly expelling all reactive materials from the core to prevent a runaway catastrophic failure is simply prudent. Anything that can generate enough energy during NORMAL operations to blow an earth sized planet apart going critical inside a star system with inhabited planets is going to make somebody's day quite miserable indeed! Ejecting the reactant to make it impossible to achieve a critical failure of that type prevents both catastrophes. It would also make a very powerful excape thrust to push the powered down station away from any gravitating bodies. (We are talking billlions of liters of deuterium or helium 3 to power something like that. Venting it *will* move the station.)
I understand that astroengineering isn't easy, but risk management is very poignant as a concern when building planet destroying super weapons.
Consider:
Rebels discover you are building said superweapon, and seek to blow it up by destabilizing the fueled up main reactor. The resulting explosion will send very high energy debris all over the system used for construction, essentially making the system useless for habitation, or for any further harboring, as it causes extinction level events all over the system in question from falling debris.
Rebels discover your completed superweapon as you move the behemoth around. (Seriously, do really didn't think that moving something the size of a moon around wasn't going to cause gravitational effects that could be measured LONG before you entered firing range of habitable worlds? For real!?) This gives them time to get sabboteurs aboard to steal technical data or worse, and you suffer the "2m exhaust port" failure...
OR...
In either of the above cases, the rebels ATTEMPT to light the main reactor using a cascading failure, only to have the cascade be intercepted by a safety interlock on the exhaust port, as reactant is simultaenously ejected to propel the station away from either the construction yards or target planetary system, and simply powers down primary power systems. Without main power, main engines won't come on, so the station becomes just another orbital mass. It would take emmense amounts of fuel to repower the main reactor, so if the rebels try to capture the station, it still won't be going anywhere, and your conventional assault fleet can mow them down. (Not to mention the hundreds of thousands of people you have already on the station to repel boarders.)
The first two result in a complete loss of investment, while the third permits salvage.
Hmmm.. let's think about that.
Yeah. Install the damned inerlocks and reactant purge emergency systems, OK? :D
Clearly your instructor was a slave to his own technological superstitions. Like any situation where you must sacrifice a useful commodity for a practical failsafe, the degree of sacrifice requires an in-depth analysis to find the optimal implementaton, for a given scenario.
It makes no conceivable sense to allocate 32gb of swap, on a file server serving several hundred people, running with 16gb of ram, for instance. Hell, having that much ram in the file server to begin with is questionable, unless the system is also doing full disk encryption, and thus also doing heavy math with each read/write that connected users perform. Regardless, if properly configured, memory load is NOT going to spike. 4gb of swap would probably be overkill.
The 2x Installed RAM paradigm is only for servers that are likely to suddenly gobble up RAM like it was popcorn at a ballgame. Things like climate modeling servers, shared university general purpose math servers, and the like.
Without knowing the intended function of the server, the answer would be impossible to answer. It could range from anything from ZERO, to "OMFG! GOBS and GOBS!"
Insistance that the answer is a stock, kneejerk value without accepting qualifying arguments simply tells me that your instructor is either a lazy fuck who doesn't want to think about the answers his students write in, is beholden to an antiquated paradigm of how things are done and what resources are available, or both.
I have 1gb of swap allocated on my linux box, for instance. Even running folding@home on all 8 cores, with "huge" dataset selected, it DOESN'T even touch it.
Solid rubber tires come on all manner of industrial transports.
Scrap solid tires are a very real prospect.
Given the weight on top, I find it hard to accept that they are air filled tires.
Since it doesn't go fast anyway, solid rubber tires, (or tires filled with an inert solid of some sort) would make much more sense.
In which case, a .22 round is only going to either get lodged in the tire, or bounce off. Simply because the tire is exposed doesn't mean the tire is air filled. (In fact, an air filled tire would be beyond the critical limit for sidewall pressure with that much improvised armor on top. They would pop.)
A cheap trick would be to fill the tires with dry, fine sand, THEN inflate to pressure. Doesn't solve the "guns make holes in the tires" problem, but also prevents the "hole in tire causes immediate immobility" and "tires suffering too much sidewall pressure" problems.
Again, such tires would NOT be capable of highway speeds. 20mph would be pushing it to the point of melting the tires. This is a heavy, gun carrying metal turd. It won't be driving that fast anyway.
If I am not selected, it won't hurt my feelings at all.
But I will certainly never go, if I don't apply, now will I?
As for speaking math, I speak it just fine. You are just suffering from extreme crainial rectumitus due to approaching a difficult problem from a preconceived point of view. (Hint: you can't be objective, if you have already judged.)
Good day sir.
Hot jupiter on outer edge of habitable zone with small rocky moons resolves this problem.
Specifially for the moons.
The moons will tidelock with the gas giant, not the star. This gives the moons a defined day/night, and seasonal eclipses. Day and night would be long, depending on the orbit of the moon around the giant, but well defined.
Needs to be on the far outer edge of the habitable zone because of tidal heating.
Whatever happened to Caveat Emptor?
As long as the statement isn't something seriously harmful, like "asbesto-brite! The SAFEST, all natural toothpaste on the market, now with even MORE of the microfiber asbestos you know and trust!"
Misleading and dangerous advertising should be a crime, but giving a rounded (within the actual rules of rounding numbers) tally of your userbase or consumption is just plain silly.
It shouldn't be government's job to make sre the day traders don't make stupid trades, and research their "leads" first.
Buying stock is a risk based venture; it should not come with a presumption of gains, nor with implications of full price refunds for investors with buyer's remorse.
When it comes to the stock market, Caveat Emptor should reign supreme. Let the buyer beware.
*shakes head*
You are not worth my time AC.
It is quite aparent you have never worked a day in your life doing any of those things. (Amusingly, they are things I have done.)
But to educate you further, coolant in an NC machine is pressurized. It sprays in jets to blast the chips away. You could operate one in ZERO gravity, as long as you also had a wet vac running in the machine envelope. (This is a commonly added option even! How do you think vacuum table fixtures work?) The tradjectories of the chips is moot. The envelope is closed, and coolant and chips spray all over inside even in earth gravity. The machines are designed to deal with that just like they are designed to deal with humidity and oil vapors.
But of course, imagine a totally fucked up and ramshackle operation with everyone sleeping on cots in the machine shop, with a unified pressurized habitat, because that would be such epic fail, it would fit perfectly with your internal monologue.
You have consistently resorted to personal attacks on my inteligence, made faulty assumptions about my work history and mental health, and have all around refused to admit any of the glaring faults in your arguments despite repeated attention being drawn to them.
But of course, because I misspell a word or two, I must be an illiterate yokel wo can't even tie his own shoes. Because, you know, actually evaluating that glaring nonsequitor would contradict your world view.
Go complain to somebody else, and be a sour, bitter, shriveled husk of a human being someplace else. I am sure there is no shortage of things you can go complain futilely and impotently about that don't concern you in any fashion about, like you did here.
Seriously. You complained about having to spend money on a non profit, contributions funded mars mission that won't cost you a dime, did so shamelessly, and attacked me and every other reader of slashdot with a shameless stereotype that does not represent reality in any fashion.
I will still apply on their roster, regardlesss of your misguided and erroneous points of view. Your argumentative and needlessly negative and acid candor have in no way discouraged the decision, and in fact, only demonstrated why people who CAN do things should sign up for this mission, and try to make a difference someplace else, away from frighted, sour, and small little people like yourself.
Good day sir. Enjoy your self-imposed misery.
And also suffer from interference effects from being a very low power or passive antenna by necessity of design.
Eg, somebody turns on the microwave, and suddenly your vision goes dark as the LCD's data antenna gets swamped with noise.
Also, lots of people wearing said LCD contacts in an enclosed space would have competing signals in the same shared band.
Wireless data transfer always runs into this problem. Display tech needs LOTS of band to display fluid moving images.
You might say that the LCD lenses could be NFC devices, but then they need a bulky head piece nearby to have the NFC work efficiently.
The idea here is to produce a "blurred" image by diffracting incoming light before it enters the cornea, that the eye then focuses with its internal lens. This is accomplished using the prismatic effects of "old school" LCD elements.
(Rememberr in the 90s whe color LCDs came out, with TFT displays? Remember how if you looked at them from an angle, all the colors were fucked up? That is because the color image was being created through prismatic diffraction.)
Combining several layers of these "prism" LCDs, along with some generalized raytracing on the part of the image processor, and the contact lenses would alter the incoming light such that a phantom image would be produced inside the eye, and appear as if it were a few feet in front of the user. Because the incident angle of the prism to the retina is fixed, the chromatic abberation would be fairly minimal, but some "pretty rainbow effects" would be unavoidable.
Much like a modern LCD has a prismatic layer before the LCD layer, you would need two LCD layers at least to get a reliable diffraction technology. The first layer selectively polarizes the incoming light, and the second layer selectively diffracts it to produce the "hologram illusion".
For lack of a better term, it would be a prismatic psycho-optometric display.
Some pretty sophisticated processing would be needed to generate the projected images though. The image would have to be generated out of focus on the corneal display layers, so the eye itself could bring it into focus. Otherwise it would never work.
Again, opaque images wouldn't be possible without completely diffracting the incoming light, and making you completely blind to the real world. Ghostly, and candy rainbow colored hologram like images would be about the best you could do.
Worse, remote attack induced epileptic seizure, caused by cycling the LCD at 25hz.
You think the annoy-a-tron, and the universal off button remote were power trips for angry nerds? Try having a bluetooth dongle that makes people have siezures.
Instead of displaying an image the traditional way, it could simply be used as a prismatic refractor to alter incoming light to produce the 'perception' of having a distant image.
Eg, your eye's muscles focus "far away", because that is where the image would resolve from the controlled refraction done inside the lens.
This would be comfortable, but images would never appear opaque. (Relies on bright ambient light, and defraction of incoming light. Shadowy, shimmery outlines with candy pastel colors would be about the best you could do without completely obliterating the light patterns entering the prism, and blinding the subject to the real world.)
This would need multiple layers of LCD prism to make work though.
That's most likely "floaters", and not dust on the cornea.
http://www.drhaefs.com/medical_eye_exam/eye_floaters.html
Essentially, they are sluffed off epithelial cells floating around in the humor inside your eyeballs.
about the best this could be useful as, is as a flash protection optical device. Couple a thin film photocell to the LCD layer, so that a bright light automatically powers the LCD and dims the light that reaches the eye. That way it wouldn't need all that data bus hanging off of it.
For an image display? Useless. The focal distance is way too close for the human eye. The resolution sucks balls. Displaying an image would require a data bus, and I don't want that crap irritating my eyeballs by hanging out plastic ribbon cables.
For welding goggles? Kick ass!
Protecting soldiers from flash burned retinas? Kick ass!
Displaying swirlies on your eyeballs as a conversation piece? Dude, you have ribbon cables hanging out of your eyes.
Augmented reality? What the fuck are you smoking? I want some.
Newsflash.
This is a NON PROFIT venture, funded by CONTRIBUTIONS.
Know what that means dickweed? It means it doesn't cost YOU a dime, unless you donate!
Complain about paying for it some more, asshole.
As for living in a tincan with 15 other people? I really wouldn't mind. Seriously. I am ambivalent about human company. They could be stark, egregious exhibitionists that fuck goats right next to me and I wouldn't care.
Also, my disdain for YOU does not mean I hae disdain for all people in general like that.
Also, your insistance that mars has "zero or low gravity" betrays your insane ignorance.
The 6 month trip to mars is just that. The trip there. The colony is not an orbital one. It is to go on the martian surface.
Mars has metal ore deposits. That is where said blacksmith gets raw materials.
The colony needs to extract mineral oxygen to suppliment its supply, and that is already a fair portion of the refinery aparatus for metals right there, if efficiently designed. YOU GET METALS BY REFINING MINERALS FOR AIR, fucking idiot. It is a fucking biproduct!
Mars has a surface gravity of .38G. NC machines are built "heavy" to supress vibrations, not because they need to weigh 20 tons. Being 1/3 earth weight does not reduce their inertial properties. A 20 ton NC machine takes just as much energy to push on earth as it does on mars. It only makes it easier for a crane to move it into the machine shop as the shop is being built. Most NC fabrication tooling mechanically holds the stock material with vices and fixtures. Gravity is unimportant to any of that. Gravity only comes into play in removing chips from the workpiece, and controlling coolant. Mars DOES have gravity. Chips will fall away, and coolant will flood just fine.
Gasses produced by NC mills are not that dangerous. Mostly water vapor, and volatized lubricating oil. Also, NC machines can be designed to use compressed CO2 as coolant. There is a copious supply outside. It can be safely vented right back outside. CO2 coolant is especially commonplace for aluminum and magnesium milling.
Clearly, I know *a lot* more about this than you do. Insisting I have no idea what I am talking about after I have consistently poked holes in your arguments like this does not improve your position.
It must be sublime, lieing to yourself that you know everything every day.
A mars colony would have to establish on the ground manufacuturing almost immediately. It would need it for the raw materials you speak of, like oh... oxygen and water.
The martian soil is heavily loaded with iron oxide. That is why it is fucking called "the red planet." Processing the soil would be necessary to do pretty much *anything* with it, given that it is contaminated with perchlorates, and other salts that render it unsuitable for agriculture, even inside a habitat.
How's this for you:
You collect the dirt along with dry ice and frozen water ice from the subsoil. It is contaminated with perchlorates. You bring the dirty ice to the colony site, and process it this way:
1) heat it to 500F, to liberate all the water and chemically bound oxygen. Run this through a gas fractioning system. This gives you pure CO2, O2, and water. How you heat it is not important. Big assed mirrors would work if you can keep the dust off. Most likely a small fission powerplant would be used though, and the heat would be pumped into the living quarters to keep it habitable.
2) return some of the sequestered water to the soil sample to dissolve the salts present. Extract the saline water, and distill it. This gives you calcium, sodium, potassium and other alkali earth chlorine and sulfate salts, and reclaims the water again.
3) vibration segregate the soil. This seperates metalic ores from less useful silicates.
4) use the silicates to manufacture glass for solar collection, mirrors, fiberoptic cable, and fiberglass insulation. What isn't useful for glass, is used as subsoil in agricultural habitats.
5) chemically isolate the salts from process 2. Process them into essential inorganic strong acids needed for any useful petrochemical operation. (Phosphoric acid, sulfuric acid, hydrochloric acid, and pals.) Treat the metal oxides with strong acid cocktails, to get transition metal salts. These have uses in everything from agricultural fertilizers, to feedstock for metal refinement. The high CO2 atmosphere of mars would make it very useful for producing concentrated cabolic acid to fascilitate these conversions.
6) mars has depleted its atmospheric free O2 reserve almost completely. Subsoil iron, copper, tin, and other valuable structural metal ores *will* be present. Clearing the surface soil for the perchlorates and other raw materials will expose bedrock where these minerals are found. This is what you refine into feedstock for additional fabrication systems and habitats.
So, things the marsian colony will need include:
A nuclear fission plant
A gas fractioning system
An industrial electric kiln + glass furnace
An industrial induction heater and metal foundry crucibles
An industrial wet chemistry complex
Human habitat structures (includes water treatment and all that)
Heavy earth movers and mining equipment
A dedicated machine shop to maintain the earth movers and mining equipment
Agricultural habitats
Recreational structures
The NC machining systems would be inside the machine shop, and would be mission critical equipment.
What you seem to fail at understanding, is that simply because the air outside is lethal, that does not mean local material harvesting is impossible, or undesirable.
As for being an idiot, all you have to do is read the primers for this mission to know that using native materials is EXACTLY the proposed mission for this colony mission.
That means they will NEED people like me.
That you don't like that fact, or think the mission is doomed to failure doesn't ammount to shit. It just means you shouldn't go.
Indeed. There is nothing to be done about china being stupid with regard to the internet, and that is as it should be. The free internet will just ignore china.
However, any appeals made by OUR congress critters concerning "free, open, decentralized control" is really just doubletalk for "controlled by our hedgemony of media and telecom interests, with no oversight."
Really, "free and decentralized", in regard to the way the internet was concieved, is that there is no distincton between clients and servers, and that ISPs are mere dumb pipes.
That is *NOT* what these lieing dirtbags have in mind.
*shudder*
What you really mean is that US politicians unanimously voted that they should have absolute control over enacting draconian restrictions on the global internet, and that those "european commies" should have any say involving red blooded american technologies and interests, and that the rhetoric about bottom up, decentralized administration is merely a red herring to keep those watchdogs distracted while they aid the henhouse.
(Spasm)
Sorry. I don't know what came over me there. Have you seen Aldus Huxley anywhere? I think I need my daily opiate injection...
What are you talking about? Many engineering students make modifications to vehicles, purely for pleasure.
The issue is simple:
If I WANT to tinker, *I CAN*.
THAT is the freedom being discussed here. I can't just decide one day that I am dissastisfied with the windows file copy dialog box's estimated time to completion algorithm, bust open the source code, and tinker on it.
I *CAN* do that on linux. (Moreover, if my reimplemetation is superior, the linux community eagerly wants my changes!)
If I *want* to modify my fuel injection system on my vehicle, I can. The hood isn't welded shut, and the ECM isn't designed to kill itself when tampered with. Compare that with say, an xbox360 with efuses, and tamper tape.
Stallman is definately a crackpot in a large number of ways. (Harvesting fresh footfungus in front of an audience and all that..) however, arguing about this level of freedom, even if people choose not to make use of that freedom, is definately to the betterment of mankind, and should be supported.
Also, just so you know, turning out a screw on an NC lathe takes all of about 5 minutes.
Unlike the fantasy world you live in, I actually work in a production environment. I know what you will need to have a successful colony startup.
You approach it from the standpoint that it will always fail. That is why you do not see the value in someone like me going. (You are a selfish whore, who wants me to stay here and design pretty toys for YOU to consume, here on earth instead.) Newsflash. I don't want to work for you.
[Useless in space]
Tell that to apollo 13 astronauts. The ones who had to shove a square peg into a round hole to have breathable air. Shit happens. Having an engineer on board the mission is vital, especially one who can make creative fixes. It takes 6 months at least to get a shipment from the earth to mars. A colony simply can't wait that long, nor could apollo 13 wait for mission control to shoot up a replacement co2 scrubber. They were damned lucky they were in close orbit of earth, and had near realtime communication with ground team engineers. Otherwise they would have died up there.
Mars has several MINUTES of com latency with earth. Calling tech support on earth is NOT a viable option, wiseass.
Your whole argument can be lampooned like this:
"You are a blacksmith, and your anvil and hammer take up too much room in the cargo hold, and take up weight that can be used for food! We don't need you in the new word, we can send ships back to england to get all our horses shoed, get nails, and fix our plows!"
In short, you are an idiot, and don't have the slightest clue what you are talking about.
I have this nasty habbit of watching the behavior of other people, and am very interested in how stereotypes develop, how they relate to group demographics, and how they also fail to describe individual people.
I have had the great (mis)fortune of being able to observe "important" people in many niches, and levels of "importance", and have come up with some general rules of thumb concerning their behaviors. These are stereotypes, of course, and should not be seen as gospel, or as describing individuals.
That said, the stereotypical "important person" (I keep using that phrase, because it covers a large demographic ranging from senior managment to politicians, to police officers.) Is actually very insecure about their position. They have worked very hard to get into their "important" position, and are terrified of being displaced, either through their superiors replacing them with a better employee, or through discovery of their being a crook.
This insecurity makes this stereotypical person very paranoid, and prone to establishing elaborate plans and collusions to prevent the possibility of competition for their position. It also makes them very susceptible to "terror", and they react very agitatedly and aggressively toward any 'percievied' threat.
A good example of this comes from a friend of mine who works with/near city government of his small town. Shortly after the sept 11 tradecenter attack, this small city government (under 100,000 residents) "increased security", was actively looking for terrorists, and had a major panic attack when a passing pedestrian left a backpack in the lobby while sad pedestrian used the public bathroom. (For real, they thought he was a bomber.) The recognition that they were simply not that important to attract the attention of organized terror agencies simply didn't kick in even once.
Due to this hysterical paranoia, they seek any and all means to "feel safe", which means they have absolutely no mental barriers against locking innocent people into padded rooms for discussing "scary" topics, or even just discussing the shortcomings of our stereotypical "important" people.
We can see manifestations of this in the US government, where serious discussions of enacting "indefinate detention" without a trial, or oversight "for national security" took place not all that long ago, and was narrowly struck down.
Being told that the measures that make them feel the most secure, are demonstrably the worst measures they could ever attempt when wanting to actually BE secure, will usually make them confrontational, and increasingly paranoid. They have an uncanny tendency to have a superiority complex, that prevents them from accepting professional advice, if that advice goes against what they believe. They view such offers of policy advice as attacks against their credibility and viability as leaders, and not as the healthy, helpful professional advice that it is. In order to get them to enact outside advice of this nature, they have to be duped into thinking it was their idea first.
That has not occured with this study. This study directly contradicts the currently held practices of important world leaders in dealing with people discussing "dangerous and scary" things, and will be viewed with derision, and outright contempt, (and more than a healthy dose of fear.)
It will be mocked and ridiculed behind closed doors, completely ignored in public commentary and the press (unless the press brings it up, then expect diversionary tactics), and burried. The researchers themselves might even experience difficulties getting more grant money, though the cockblock will be subtle.
In short, don't expect this study to bring enlightenment in our leaders.
