Excuse me while I sit and contemplate why I would ever need to know the inches in 463 miles. Or converting tons/sq foot to sq in. Ps its 2 ton/in sq took all of about a 3rd of a second to get. And FYI you rarely ever judge things like that. More realistically would be lbs per inch on a beam (figuring the moments and shear along a beam) Honestly I can throw any number of useless groupings of numbers out there to have you try and judge how easy math is. And all of these problems you all keep doing are easy round numbers. Try this on for size. Whats the volume of a cylinder 880mm tall, and 610mm in diameter?

Never had to measure the volume of too many compressable substances in my kitchen. Though usually compressable gasses are measured in terms of pressure, temp, and/or volume. Then I pull out my trusty kitchen scale, tare it out with a small glass bowl, and measure out what I need. Dont try and push your argument by trying to measure mass by volume when you dont have to. See above. Minor pressing of a button to switch modes of the scale MAY be necessary. Well cant fault you for not having stuff in stores. Periodically I like to take stabs at a lot of asian dishes, and run into problems getting spices called for. But my local supermarket has been getting better about those kinds of things.

Thing I think is kinda funny about a lot of these posts. Is that the general consensus is that the US is being lazy to switch over. Officially we are. And ever since 2nd grade, I've learned both systems, all the way up through Engineering school where 95% of our work was done in metric. (thermo class) Note that our machining courses, all our math had to be done in imperial though (because all the old lathes and mills were all built with mils in mind, and buying new 1s built with metric in mind for controls.... well they certainly aren't cheap) Never had any problems with other countries either submitting metric designs built to inch spec for production. Actually I've run into more problems with old machinists turning out parts that are backwards (due to a change in the standard of drawings, that happened a number of years ago.) Honestly, I wonder if you're actually serious. I've been traveling all my life. I go to Germany, my speedometer is in Km/Hr, the signs are in Km. I don't need to do a mental conversion into mph, to figure out its going to be a half hour for me to get from where I am, to where I'm going. I come back to the US, with a car that says mph, and the road signs say I'm 96 miles from seattle. Its not difficult. If you're trying to convert stuff into your system like that (and then bringing in the nautical mile is the real thing that makes it ridiculous) thats your own problem, not a problem with the US using Miles for distance. Unless of course you brought your car over here... but that makes no sense either, because of the probably 50 rental cars I've ridden in in various countries. All of them that were for metric focused markets had Km/Hr in bold, and mph in small within the speedometer, just like most cars in the US have both systems included. Only cars I ever see that DON'T have both systems on them with regards to speed, is sports cars, and some older 50s-60s american cars. (on mention of pudding mix)Hey some old lady taught me a number of years ago to throw a pack of pudding mix in with the batter when baking a lot of cookies. Cause it adds flavor, and it keeps the cookies soft and delicious for a few days longer than without (nothing sucks more, than getting home. wanting a cookie, biting into it, and having it be all hard and depressing when you just made them the other day) Well in visits to Japan, England, Greece, Italy, and Germany, I saw them in all of the people I visited's houses. Were other brands but were basically the exact same thing. TBH I can't imagine trying to run a kitchen without something like that.

Well, a bowl with water, or a sphere half full (probably better) graduated on side, along with an external tool (a kind of pointer) would be primitively able to tell your current position... if you were good at knowing the stars. Add a floaty into it with a magnetized needle, and now youve got yourself a compass also. (Which if you rotated the thing, you can use the existing graduations for compass angle)

So. Been 6 months. Any set of rules for this thing yet? Or is it gonna just be freebuild, post your awesome, for what we do.

Sry man. Childish arguments (specifically the last few pages about scales, sticks of butter, pinches, and cups) begit childish responses.

Well as a person of much experience in the art of chefery. All i can say on the subject is you're all a buncha scrubs who need to get over yourselves. Like seriously. HUR DUR SCALES R HARD, MEASURING CUPS, STOOPID AMERIKJINS DERP. Seriously you're a bunch of imbeciles on this portion of the debate and you should all be ashamed. FURTHERMORE. When i get a recipe that calls for metric units, know what I do. I turn the damn measuring cup around, and read the other side. Like a mature, well rounded (c wut i did der?) educated individual. Then I bake some cookies, grab some milk, and my bird, play some KSP, and enjoy myself. Too bad yall with your issues with all these different ways of doing it will never enjoy chocolate chip cookies on the level that I make them. Cause my recepie calls for another outlandish unit. "X bags of vanilla jello pudding mix" (ofcourse you can use other flavors too)

Well since efficiency is part of the topic. Opposed piston diesel anybody?

I just make it up as I go. You can learn to program in a couple weeks if you want. Mastering a language... god only knows

I know some rely on projectors for vision, with some custom software to "shape" the image output to match the curved "windscreen" and give ~270 degree fields of vision. But you require some pretty damn expensive projectors for that. As far as tilting and rolling. Sure, can be done... for a couple grand. Best bet would be starting by rigging up a stationary cockpit though. I know I helped a friend build theirs. Even went so far as to building a couple instrument panels and using an arduino mega to make those operate/interface with the computer. Its a little over the top for me. But a lot can be said for your rudder pedals not running away from you during successive maneuvers.

The reaction is too slow and unpredictable to run into an engine. Also theres a lot of extra material involved that goes to waste.

I kinda fail to see the advantage... youd still need a fairly complicated compressor, and unlike a jet (centrifugal compressor, or axial flow) there would be extremely high chances of flameout due to the piston engine not feeding the proper amount of air. Like I get it and it could be done, hell could probably build something along these lines out of an old 8c radial (2 rows of 4) RC engine ive got (take the cam out of 1, have a new 1 made that opens the valves every stroke) Run the exhausts from those into a CO2 canister (to stabilize the pressure, less pulsing) and then feed that compressed air into a pulsejet. Convoluted as hell. But would be efficient at flying low speeds due to the prop still working. Then compressed air is there ready to help start the pulsejet. Ofcourse, by that point though... I could have just spent $1500 on an actual RC jet engine which would be several times as efficient, and less likely to break.

Hey im on my phone so not really up to do the math. But assuming this thing is a ring at GSO and tethered (so at GSO orbital speed) What would be the centrifugal force, and by extension, artificial gravity on a person standing on the ring, head towards earth, feet to space

Well even if rotating didnt help, it would probably have to orbit earth (seeing as the various parts would have had to be in orbit before being assembled)

Filled it out. I can say that Ive learned a lot about astrophysics (and aeronautics) due to playing KSP and the forums here and such. But the game itself isnt really "educational". I know people who play this all the time and cant put 2 and 2 together and understand why stuff we do in space is done that way. At the same time though, a lot of others who Ive shown the game to who got into it. KSP is more like a gateway. You can read about say, how we put satellites up in space, or how an orbital rendezvous is accomplished. But it probably never clicks in a persons mind. Give them your laptop with KSP on it for a week though, and let them try and do it themselves. Suddenly it starts making more sense. Its a way to give a person a hands on way to learn as opposed to just reading or listening. I know that when I was subbing a couple years ago for a physics teacher and was doing the little bit at the end of the year about space orbits and such. Was literally 2 days before those classes that I found KSP. (Already had a prewritten plan from the normal teacher so I didnt even really understand a lot of the stuff.) Wanna make a good presentation for some kids that getting to orbit takes more going sideways than vertical? I remember when I was in school we watched an expensive produced documentary about that stuff. When I was teaching, I made that documentary in realtime for the class, and let them try to get that damn rocket into orbit. (Also used it for showing orbital transfers, free return orbits to the mun like Apollo used, GSO, the coriolis effect. And various others.)

Tried it. I guess its doable. But for gaming, you basically need a gamepad controller or a HOTAS setup so that all controls are at your fingertips. Cant really go hunting around a keyboard for the flaps key while dogfighting with an Oculus Rift

Well my humble opinion. I do a lot of joystick games. (Elite Dangerous, War Thunder, Il2, LockOnMC, DCS to name a few) and in the case of elite and war thunder I have had opportunity to play with an Occulus Rift, and track IR (Im poor though so im usually restricted to a hat switch for view controls) Now dont get me wrong. OR and trackIR can VASTLY improve gaming experience and situational awareness when compared to a hat switch. But they would never be able to match gaming in a cockpit with 360 degree vision. Ofcourse this is just a gamers perspective of those systems. The second you start trying to train pilots though, those full cockpit simulators are probably a must next to actually flying.

Actually it would probably be more like a small explosion next to your vehicle, that while transferring energy to what you're protecting, it interferes with the incoming blastwave. You probably end up getting hit with the whole blastwave nonetheless, but not all at the same time, spreading the force out over a time. Similar to recoil systems in big guns.

Generally

I know some motherboards prefer having a single RAM stick in a particular slot (not necessarily the 1 you think is "first") and will run a tiny bit faster if your single RAM stick is installed there. (Goes out the window with several sticks though)

Well, if you spent the money for a big balloon rig like what they used for whatshisface to make his high altitude skydive, you could get a fairly sizeable rocket up there... but would probably still be quite limited in max altitude. I think some of the larger rockets Ive built have scraped up to a half mile or so (before i started getting angry letters) if you were to line a real stack of motors up in a way so that they'll stage themselves, you might pull off a few km above your launch altitude. 10km would be some real wishful thinking, but probably not impossible. Cost if this mission would be quite high also. By some point, you might just consider buying some old Sidewinders or Atolls off some military, and use those as your engines (The AIM 9 has a 7-8 mi range for some of its early models, that you could probably buy for a couple grand in the middle east, would probably put you on some watchlists though.) Curious, how well did it go underwater (or was it like you launched it from underwater to the air?)

Biometrics are of no use to everyday devices such as phones and laptops, they are better when applied to hierarchy level related access and such, not to protect stuff from external attacks. Anyways, someone who's worried about security would choose a complicated password instead of biometrics, they wouldn't mind the inconvenience of having to type 12+ chars to get to their valued stuff. Yeah for a long time I had a "triangle" as my swipe, noone ever got it. Cute background (what char) Thing that bugs me the most on password safety, is password "security questions" a pregenerated list of questions that can be answered by stalking most peoples facebook pages. Whenever I get the chance, I make up my own security questions. Only 1 other kid in the world knows the answer to my "Cuando es tu cumpleanos?". And trust me it aint my age. That and password lengths. Seriously between 8 and 12 characters. The hell. Is space that tight on your database that you cant splurge and give us 20 characters. I could at least make a statement with that much space. I remember 1 game I used to have subbed, they let you have a 256 char password, and a 256 char PW hint. If someone wanted to try and brute force that anagram symbols, more power to them. Theyd be better off coming and beating it out of me with a $5 wrench. But hey, myself and most of my guild have all simultaneously had our WOW accounts "hacked" a few dozen times now. And thats been the source of the most of my recent password changes, so no matter how good a PW you make, doesnt really matter if the server you are connecting to has crap security.

Used to overclock years ago all the time. Every machine, an AMD athlon not being overclocked was like a crime against humanity. Nowadays, not so much. Most games are so much more optimized, and processors and gfx chipsets are so robust in their stock states, you really dont need to bother. And it saves on stupid crashes, jittery gfx and framerate drops when the cooling weakens for a split second because your cat jumped up on your desk.

I thought most of it on the landers and such was Kapton insulation
