Am I doing something horribly wrong?
Yes, you are expecting to make more than a tiny amount of money for a tiny amount of effort. That expectation is horribly wrong. If anyone told you mining was a get-rich-quick scheme or a way to get free money, then you were lied to. Mining with a PC is simply not profitable under most circumstances, and hasn't been for a long time, and makes about as much sense as digging for gold with a garden spade.

EDIT: Typo.

Fees can be (and, in fact, already have been) reduced in response to rising exchange rates.

Sure, just set up some PKI and require that blocks be valid, and signed by a key that was signed by the central CA.

That might sound sensible, but there's a key problem: who/what will be the CA? Would people really trust me/a small group of techy people more than their local government? In the case of the govt being the CA, then that kinda defeats the whole purpose of making a cryptographic local currency; it may as well be a paper local currency.

wow thanks a lot Foxpup, that's really interesting, he didn't seem to mention any of this in the troubleshooting for it and so on >_< and this is supposed to be a beginners tutorial lol! Tongue I copied it exactly just to see whether I was forgetting or something, looks like there are bits wrong with his code but I'll double check again and it looks like there are.
It's for beginning game programmers, ie, programmers who are experienced at writing other applications and wish to move on to the more specialised field of game programming. This tutorial assumes basic knowledge of C++. If you have never done much programming in C++ before, you should probably start with the basics before continuing.

Quote from: Lazy Foo' Productions
Q: How much C++ do I have know to start game programming?
A: For my SDL tutorials, you must have a decent handle on the following concepts:
Operators (+, -, *, /, ++, --, +=, -=, etc)
Controls (if, else, switch)
Loops (while, for)
Functions
Structs
Arrays
References
Pointers
Classes and Objects
How to use a template.
Bitwise and/or.

The articles might require you to know more, but they'll mention it beforehand. Of course the more C++ you know, the better. To make anything complex you'll need to know inheritance, polymorphism, templates, and STL. Eventually you'll need to know exceptions, operator overloading and the whole language.

Make sure you know these concepts well. Don't just skim over them in a C++ reference book. It doesn't matter how much Java/Python/C#/Visual Basic/ASM/HTML/whatever you know. You have to know C++ to be able to learn from the tutorials/articles.

Do you know of any up to date tutorials that won't bugger up on the latest version of SDL? I particularly like this library because it means I have to go and make some art assets right away which is nice, anime characters time woot! Cheesy
I'm pretty sure this tutorial is up to date with SDL 1.2 (the latest stable version). SDL 2 has a lot of changes, but I think it's mostly the addition of OpenGL and haptic support, I'm not sure how much (if any) of the 2D graphics stuff is being changed. Anyway, SDL 2 hasn't been officially released yet, so it's a moot point.

I thought buying this way I can often catch the lower price than market average,
You won't if the prices are going up. In that case, your method forces you to wait 24 hours before buying, by which time the prices are even higher. But if the prices are going down, you should wait longer than 24 hours to buy, otherwise you're stuck with the higher price, so that's no good either. In order to buy at a lower price than average, you need to know whether the price tomorrow is going to be higher or lower than it is today. But you don't, so you can't. You just have to accept that day-to-day fluctuations mean you can't always get the best price.

If you're in it for the long term, you shouldn't bother even caring about day-to-day fluctuations at all. If the price goes to $1000 or even higher, what difference does it make whether you bought at $124 or $125 or whatever?

There are profits to be made, But you need to know when to quit for the day.

People seem to think it's always up, up, up!

Need to get up 10% - 15% and just stop. People keep on going and it gets bad quickly.
Rubbish. You're just as likely (actually, slightly more likely due to the house edge) to lose 10-15% initially, and if you keep on gambling to try to "recoup your loses", you're just going to end up losing all your money.

What you suggest is the same idea as the Martingale strategy, in which the gambler bets increasingly large amounts, so that a single win will recover all previous loses with change left over. It doesn't work. It just turns a small chance of winning a large amount and a large chance of losing a small amount, into a large chance of winning a tiny amount (in relation to your wager, which quickly grows to be enormous) and a small chance of losing everything, giving you the same odds as Russian roulette.

error: 'args' has not been declared
There must be no comma between char* and args[], as they're part of the same declaration (that you have a array of pointers called "args" of type "char"). With the comma, it thinks you have an anonymous pointer of type "char", and something completely separate called "args", though it doesn't know what this thing called "args" is supposed to be, hence the error.

error: 'SDL' was not declared in this scope
error: expected ';' before 'Init'
You need an underscore between SDL and Init, with no spaces. "SDL_Init" is one function. With a space, it thinks they are two separate functions called "SDL" and "Init" (which don't even exist, causing the first error), and expects a semicolon between them (you always need a semicolon between statements), which is the second error.

error: 'screen' was not declared in this scope
You forgot to declare it (or you declared it in the wrong place). You should have "SDL_Surface* screen = NULL;" immediately after (or immediately before) "SDL_Surface* test = NULL;".

its not really a dice game tho.... its just a statistics game... you cant really have a dice with 64,000 sides can you... it would just look like a round ball.

You could just roll one ten-sided die 6,400 times.  Grin
Actually, you couldn't. That would result in a normal distribution (in which numbers closer to 32,000 are more probable) instead of a uniform distribution (all numbers equally probable). To get a random number from 0 to 65,535 (which is what SatoshiDice actually uses, not 64,000) from real dice, you would need five 8-sided dice (or roll one 8-sided die five times) and one 2-sided die (or coin). Roll one for each octal digit, then convert to decimal.

First of all, your payout from SatoshiDice won't confirm until the original transaction does. SatoshiDice does this to prevent cheating: if the wager transaction is any way fraudulent or invalid, so is the payout, so the cheater wins nothing.

As for the original transaction not confirming, that is because the sender did not pay a transaction fee, even though a fee was required for this transaction. As a result, it (and your payout) will likely take an extremely long time to be confirmed.

What's strange is that you were actually able to send this transaction in the first place. Most clients do not allow you to spend unconfirmed funds, precisely to avoid this kind of issue. What client or wallet service were you using?

EDIT: Typo.

Or is there a way to set up a wallet so that despite being "unencrypted" the private keys still can't be read?  

OR is there a way to show the private key on the computer without it being the actual private key, but it becomes something that a person sitting at the computer could understand as the private key?
The private keys must be readable by the software. It can't send transactions otherwise. Encryption is the only way to ensure that the private keys can be read by the software that needs to read them, and only when it needs to read them, while preventing the private keys from being read by anyone else. Though even that won't work if you've got a keylogger.

I'm just trying to brainstorm a way that will attempt to thwart thieves at any level, despite them knowing your password and infecting the system. The key difference is that they are not you and they are not sitting at your computer.  
It's not possible. If someone a) can decrypt your private keys (ie, they know your password) and b) has access to your system, they can steal you coins. The only solutions are to a) keep keyloggers off your system, and/or b) make it completely impossible for anyone to access your system at all (cold storage).

Bottom line, if someone or some program has access to your computer, they can do anything that you can do, including access your private keys and use them to steal your coins (using their own software, if your software has "safeguards" which don't actually provide any real protection). No lock is safe from someone who has the key.

There are many expiriments working toward getting a hand to grow out of your shoulder. It appears the the first person had this successfully done.
Ah, yes. That was the other goal of the cloning project: to clone spare body parts, so that if you lose one, the doctors have a convenient transplant option. Although you can't see it, both these guys also have a bunch of ears growing out of their backs.

Yes, it is a secret cloning experiment. But what the government isn't telling you is that the experiment was a failure. You see, the cloning process has a horrible flaw. For reasons which are still being investigated, all clones have a different eye colour to the original person. However, unless you already know the original person's eye colour, there is still no way to tell which is the clone and which is the original (clones are usually evil, unless the original person was evil, in which case the clones are usually good, so that's no help either).

when and how did the euro symbol € inserted into ascii character table?
It isn't and it never was. The following is a complete list of all printable ASCII characters:
Code:
 !"#$%&'()*+,-./
0123456789:;<=>?
@ABCDEFGHIJKLMNO
PQRSTUVWXYZ]\[^_
`abcdefghijklmno
pqrstuvwxyz{|}~
See? No euro symbol. Or many other symbols for that matter. That's why nobody uses ASCII anymore.

Let's do a proposal to insert the bitcoin symbol into ASCII character system, like all other currencies.
Um, ASCII doesn't have all other currency symbols, or even any currency symbols other than than the dollar sign. ASCII also cannot be changed, but that's okay, because hardly anyone actually uses ASCII for anything anyway.

"Great Rates"? Your price is higher than SpendBitcoins! Shocked SpendBitcoins can at least justify their price with their brilliant service and reputation for reliability. You, on the other hand, didn't exist until three days ago, don't even use SSL on your site (an absolute must for any site handling money), and have a photo of a stereotypically attractive woman (a well-known hallmark of scam sites), who, to be completely honest, looks like she wants to rape me. Lose the woman, get an SSL cert, and lower your prices. I can't even begin to take you seriously until you do that.
