A Typical Goon posted:If I've lost all the keys to my car, what are my options? So far I've heard go to the dealer or go to a locksmith and get them to make me a new key. However, I can't find anything about the costs. Anyone been in this situation and know about it? Depends on the car. My car's an old POS that nobody makes anymore. Getting a new key made from the dealer cost me $10. If you have a fancier car/key set, it's going to cost you more, but a standard old key shouldn't break the bank.

Have you checked out the New to Piano thread in ML? http://forums.somethingawful.com/showthread.php?threadid=2612320 I was taught piano as an adult, and I would suggest learning chords - simple chords, as well as how to read them in notation. Of course I can only make assumptions on how well you will learn, but for me, as a slow learner, I found chords to be a great introduction and to help me get my head around the more intricate aspects of notation.

That happened to me a few days ago. If you report it, you have to jump through a few hoops but you can change your password eventually. I had to go to a page to confirm my phone number and a robot called a few minutes later with a code I put in a text box. That was pretty much it, and I learned a valuable lesson about using simple passwords.

This is a very stupid question, but judging by the title I am in the right place! I am a very lazy person who has no money right now. I have a very special folder unrealatedly titled "The Sweatshop Experience" on my desktop. I am going to do a reformat operation, but I have no means or money to back it up to an online service/portable HDD. The folder is 75GB. Theoretically, is there any way I could SUPER compact it and make it like 1GB? The reason why I ask this is because there are some viruses which are like 500kb and uncompress to like 100s of GB's. My computer is pretty recent, and my internet download speeds arent all that great, so I think uncompressing a 1GB file to 75GB would be faster. This question probably has so many holes and dumb assumptions, but I really dont want to lose this folder, and it seems a bit fun to achieve. I'm mostly doing this for the novelty of it. vvvv: No trust me, I think I took the cake for this page. buglord fucked around with this message at 07:43 on Mar 11, 2011 |

Math question. This is definitely stupid (which means I'm in the right thread) [EDIT:^  ], I just can't figure what part of it. To be clear: I know this is wrong. I just want to know *what* part of this reasoning doesn't hold up.The main idea is this: I started thinking about circles and spheres. I think the most intuitive way of thinking about volumes (of "regular" shapes, I don't know what you'd actually call them) is as "slices" multiplied by the height/depth of the object. So in a cube, you have the area of the bottom of the cube (a square), with an area of s*s (length of one side). You assume this bottom square has the thickness 1 (as in one unit, the smallest thickness you can have and still "exist"). You get the volume of the cube by multiplying it "s" times (again, the length of a side because that's how tall a cube is). So a cube is really made up of s slices/squares. Now, I was trying to apply this line of thinking to a circle, and obviously it doesn't work. Essentially, I took half a circle and spun it around its diameter. So the "slice" in this case is the half circle (area of pi*radius^2), which is multiplied 2*pi*radius times (circumference). I've tried to depict this the best I can. Imagine the first figure spins around with the diameter as its axis, creating 2*pi*radius "slices", as seen in the second figure (where we have 5 of those slices depicted). I just can't get my head around why this wouldn't relate to the volume of the sphere. I'm obviously missing something quite elementary, but I'm not ashamed to ask about it!  EDIT2: To the poster above me: that might be nigh impossible. The reason a 500kB virus can uncompress to 100GB is because it's using a formula to (re)generate its content. So the reverse has to be true: there needs to be a formula that can describe 75GB of information as 1 GB. Unless that 75GB is essentially just files containing one single number, you might have a hard time achieving such a level of compression. Compression algorithms depend on redundancy and repeated patterns, so if the files are something like mp3s and jpgs (already compressed once), it's pretty much impossible to make them that much smaller. Just my 2 cents

At the center of the sphere, it'd be infinitesimally thin, and a unit thick at the surface of the sphere. That's at least one thing wrong with your reasoning; there may be more, but it's been a long time since calculus.

Avocadoes posted:This is a very stupid question, but judging by the title I am in the right place! Depends entirely on the nature of the contents. If it was all text, you might see as good as 20:1 compression. With other sorts of media, there's no hope 75GB could go into 1. There is some quantity of information in those 75GB that can't be fundamentally further reduced, and it's likely to be more than 1GB. Your best bet would be to amass 10-20 email accounts and dump your stuff onto as many Dropboxes. hooah posted:I'm not entirely sure, but I think the reason this doesn't work is that that slice can't be the same thickness over the entire radius.

That's at least one thing wrong with your reasoning; there may be more, but it's been a long time since calculus. The guy is reaching for polar coordinate systems. It's commendable that he thought it out without having taken calculus. The main difference between the cube and the sphere volume calculations you were trying to do is that the slices (differential elements in calculus) are different shapes, as hooah said. Not only that, but you're not accounting for the "right scale" to do your summation over. Daemus posted:I just can't get my head around why this wouldn't relate to the volume of the sphere. I'm obviously missing something quite elementary, but I'm not ashamed to ask about it! Once you take basic integral calculus (or read up on it), the adjustments you need to account for will snap into place onto your current mental model, which is sound. kimbo305 fucked around with this message at 08:02 on Mar 11, 2011 |

That's at least one thing wrong with your reasoning; there may be more, but it's been a long time since calculus. Yeah, this was actually something that popped into my head as well, but I couldn't really define why. It's like cutting an orange in half, and continuing to cut the slices into smaller and smaller pieces. You're not going to end up with just uniformly thin slices, at some point the center is going to be "one unit" thin and can't be sliced anymore even though the outer surface could. I guess this is related to the fact that if you spin a disc, the center will travel "slower" than the perimeter? I just have a hard time getting my head around it.

That is why if you spin a disc too fast, or spin a disc fast with a crack on it, it will explode from the stress. If you have a cd and cd drive (that spins above 24x) to sacrifice in the name of science, crack the cd a little and put it in, then prepare to extract all the resulting chunks.

That's at least one thing wrong with your reasoning; there may be more, but it's been a long time since calculus. You're on the right track. Yes, the slices would have to be infinitesimally thin, but there also has to be an infinite number of them. Let's not forget that this isn't the same as "stacking" circles to make a cylinder. As you're rotating these hypothetical "slices" about the axes, they overlap in the center. This overlap must be accounted for, but it is also infinitesimally small. Infinity is a pretty difficult thing to consider when you're dealing with finite volumes. A sphere just can't be segmented in this way in a volume calculation.

To make a sphere I'd have to make them "thicker" towards the perimeter since you can't go smaller than the smallest unit and that's reserved for the very center. I think the reason my figures are off is because I'm multiplying by the circumference of the *perimeter*, even though the closer we get to the center the more we "travel" (and the area doesn't decrease linearly). Mind breaking stuff for me. Appreciate the replies!

Unlike your summation, though, this is a double integral, which allows some leeway with the order in which quantities are computed.

Avocadoes posted:Compression You say you want to compress it for the fun, but you also say you don't want to lose the folder. My reply is for the latter. Make a 76GB partition on your hard drive and move the folder to that. Reformat your original partition and reinstall everything you need. Move the folder back to your fresh partition. Format the spare 76GB and extend your Windows partition into the 76GB. As for compression, do you at least have blank DVDs? You could compress it as much as it will compress and span the archive across multiple disks.

Are there any specific retail websites that are good for buying foreign language, specifically French, language books? I don't mean books on how to learn a language, but a site that sells things like Harry Potter or Game of Thrones in French as well as just general books that may exist only in French. Amazon US usually doesn't have much, and when it does its usually way overpriced. You can't of course just order from other country's Amazon sites. Places like abebooks are ok, but selection is spotty and some times its a crapshoot on price.

I believe you will be #4 as long as you have enough points. You can click "view stats" to see your "real" position listed under the Active column. Though any of the people without enough points suddenly get enough points, they will jump in front of you.

Is there an expected price drop in the Nintendo DS market after the 3DS launches? I've been looking to get a DSi XL but I only wanted to spend about $100. Currently used ones are in the $130-$145 range. My friend is upgrading and offered to sell me his DS Lite for $60 (with homebrew cart) but I'm still really keen on the XL.

A few years ago I used a program that was used to help you remember things. It be like flash cards, and you would rate on a scale of 1-5 how well you remembered it. Using this information, it would then present the flash card to you on a later date, if you rated it a 1 you would see it soon, if you rated it a 5 you would see it in a week+. What is the name of this program? Edit: Found. FullRecall is a propriety version, Anki is a free one. Titan Coeus fucked around with this message at 20:06 on Mar 11, 2011 |
