Yes, there are many utilities to do that, or you can write your own. For example: $ echo 0406b7bb1663fc7b6a8a5630038a393581fe24c4fa6da64d94fd76de758885809f40ba54c40b95040294defc84d255079b4a13d1f784c1cf271dbc0d4e864a1696 | sx addr

You'll at least need to install twisted, I'm not sure about others. When you run pywallet it should tell you what you're missing. Just install pip (python-pip?) and then install the missing dependencies.

Yeah you haven't given my information. Obviously the first step is to install python and pip. Install all the required dependencies. Download pywallet and run it with the correct options. Which are you having a problem with?

Yes, each private key contains within it the ability to know the address associated with it. So for example if you gave me one of your private keys then I could immediately steal the coins on that address, even if you didn't give me the address. Because it's easy to find the address from a private key. However if you gave me the address I can't do anything with it but look at how many coins it has because it's impossible to get the private key from the address.

You are 4x as likely to lose 1/4 of the wedding photos if you use 4 SD cards. But you're 10000000x more likely to not get paid if you lose 100% of the wedding photos by using only 1 SD card.
Brain wallets are easily guessable, you should move your funds into something else immediately.

I was under the impression, though, that I could have (I'm shortening addresses for brevity):
One wallet with its private key. 5 Addresses with the following balances:
1jAdjflsjkfsdf32423lk - 0.01 BTC
1jAdjflsjkfsdf23j44lkl - 0.03 BTC
1jAdjflsjkfsdf234234 - 0.03 BTC
1jAdjflsjkfsdf23j423l - 0.03 BTC
1jAdjflsjkfsdf2342l3l - 0.05 BTC
Now, my understanding is that you could use a "sweeper" (or import, maybe?) to take just the private key and automatically know that there are 0.15 BTC associated with it (by taking all of the possible addresses and pulling in their balances). Is this where my understanding was wrong?
Those 5 addresses each have their own private keys associated with them. If you want to sweep those funds you'll need to use each of the 5 keys. Just think of sweep as spend, take, or steal. |

I added a corrected question. It was addresses I was thinking of, not public keys. That's my fault (I'm still new to HOW Bitcoin and others work, which is also why I'm asking the question, :p).
So address-wise... how are you able to sweep all possible addresses when they are generated randomly to begin with?
As Foxpup said, the private key really only corresponds to one address. All sweeping means is that you spend whatever is in that address and send it to a new one. Imagine having an online wallet with address A And a cold offline wallet with address B, where I've written the private key on a piece of paper. If I open my online wallet and sweep that offline private key that corresponds to address B then it'll send whatever is in B to address A. My online wallet still only has address A, but it has all the coins from B in that address A as well. That's different than importing a private key. If I imported the private B key into my online wallet then it would have both addresses A and B. You can read how to get the bitcoin address from the corresponding private key here: https://en.bitcoin.it/wiki/Technical_background_of_Bitcoin_addressesThe key to bitcoin is that you can go from step 0 to step 9 easily, but going backwards from 9 to 0 is impossible. |

There are many private keys for each bitcoin address, not the other way around. But don't worry about that.
Perhaps you're thinking of a deterministic seed? Those generate a private key / public key pair by incrementing a counter, so you just need to keep incrementing the counter until you stop finding addresses with activity on them.

Buy $100 worth of bitcoins and see if you can keep it from getting stolen or losing the password for 2 months. If you can then you can buy more. Don't buy anything but bitcoin.

Are there any security measures to take when you use your wallet on a smartphone ? Also, is it possible to use your smartphone has an added security layer for your wallet ? Like 2FA or something. If so, does your wallet need 3G or 4G ? Does it need to be with a ISP like AT&T ?
If your wallet is on your smartphone then having 2FA is kind of pointless (with regards to security if you lose your smartphone) if that uses the same smartphone. |

Any wallet but bitcoin-qt will have a sweep key function. Don't import them because whoever found your phone may have them. Of course, make sure to backup your new keys. I'd recommend electrum instead of multibit.

Is there anything that is actually impossible (P=0)? If you don't count abstract math and logic (e.g., 1+1 != 2) then I think everything is possible. Physics would say that moving through time in a way that violates causality is impossible, but I think you could argue that that breaks abstract logic at the same time so it doesn't count. Some physicists would say that it is impossible to get from Point A to Point B faster than the speed of light, but even this is debatable with convincing evidence of quantum non-locality. I think it would make sense for anything to be possible because I think it makes sense that the universe itself is universal (i.e., Turing complete). It's impossible to violate the laws of thermodynamics. |

What? Overheating?! Hmm, so I guess it is not a good idea?
Are you running it overclocked? The above poster says it draws 360 W, that's 94% of its 12V capacity according to its specs on Newegg. |

The only way to trade in my opinion is to buy and hold no matter what the price fluctuates to.
That's investing, not trading, depends what your goals are ultimately. Well technically you did one trade  And I suppose you'll do another trade to cash out. |

You'll have to install a torrent client, like transmission.

martingale works 100% if you have infinite money
Martingale doesn't work at all. It doesn't matter how much you start with or how small your base bet is. The odds are with the house no matter how much you bet. And it's even worse because you're doubling your bet when you lose. Doubling your bet in a game where the house has an edge can never be a winning strategy. Not to mention even with infinite funds, at some point it would hit billions of failures in a row. So the idea that it works "100%," regardless of the number, is false. Also the idea of adding money to your infinite bankroll is silly |
