Question:

Which wallet to use, that would all keep all the different Alt currencies and bitcoin. Grin

If you want a wallet to handle multiple coins, there is UfaSoft Coin (https://bitcointalksearch.org/topic/ufasoft-coin-multi-currency-open-source-client-for-windows-58821)
If you want a wallet to handle all coins, there will probably never happen, as we have hundreds of different coins and have new coins coming out everyday.

and so the student becomes the teacher. Although in this case I believe the question was regarding a proof of work algorithm, and not the use in address generation

All thanks to you.
Yeah you snuck in while I was trying to cover up my mistake.
Edited the answer, but still didn't answer the question, because I just don't know.

Here I come with another question!

Why SHA256 and not another algo?

Pretty much repeating something I've picked up in this thread and am still taking in, so correct me if I'm wrong.
There are other algorithms involved as back up in case one is broken.

EC and RIPEMD-160.

The process to get to a bitcoin address goes:
Private Key --> EC --> Public Key
Public Key --> SHA256 -> RIPEMD-160 --> PartAddress
PartAddress --> SHA256 -> SHA256 --> CheckSum

Full address is then made from:
00000000, followed by partAddress, followed by CheckSum
All one number.

So if RIPEMD-160 were broken in future, SHA256 would need to be broken too for attacker to profit. And Visa-versa
If EC were broken then (correct me) public keys that coins had been sent from might be vulnerable, but receiving wallets that don't send would still be safe.

EC - Elliptical Curve
RIPEMD-160 - RACE Integrity Primitive Evaluation Message Digest(160 bit)

EDIT: Rereading your question, I guess it's that SHA-256 is currently best choice when measuring security provided against work done.

Great, thanks! I'll give it a shot tomorrow evening.

Alright, I'll just wait til then.

Also, I can just send 0.007 BTC to the winner's wallet if they wanted that, 1GHS is not withdrawable because it is only worth ~0.0075 BTC, you need a whole bitcent to withdraw. So give them the option to just get 0.007 BTC Tongue

dev, or danny, mind choosing another winner? I'll get the GHS sent to them, ask them to PM me or post here.

I would but I still haven't found out how to convert a block hash to decimal form Tongue

I just use the converter here:
http://www.mathsisfun.com/binary-decimal-hexadecimal-converter.html

You could do the math yourself by hand, but it's not worth the effort. The converter handles it just fine.

Rather than try to do the modulus function on such a big integer by hand, I just use this calculator:

That seems like the best way to do it. We'll use block 305604 and 305605 then. If I get drawn either time we'll use the next blocks.

Block: 305605
Hash: 00000000000000002e2b25627d27cbe11e664406f4d05cf2f00b8171d190110f
In decimal: 1132049287128551868613215852162935821461544770171095224591
Remainder when dividing by 109: 71

Someone check my work, but I think the winner is:
https://bitcointalksearch.org/topic/m.7256769

If so, then it appears that "Acidyo" is the winner.

Gah, I'll give that guy the 1 GHS if he promises to take his spamming down a level. Wink

Acidyo, please PM me to claim this gift. I'll send the CEX.io voucher code then.

You may give the 1gh/s voucher to someone else who maybe hasn't used cex.io before and can learn something from it. But thanks.

What forum services could I do to earn a bit of change? I thought of signature campaigns, but nobody really wants a newbie advertise their websites.

Actually there is one you can try that. https://bitcointalk.org/index.php?topic=636079.0;topicseen

That is the only program accepting newbies, but please note that it is promoting a ponzi (and so the ponzi owner may vanish at any time without paying)...

I tend to disagree.

Mining, use GPU na CPU. You would only pick it up, if you losing significant frame rates, when you playing games.

Huh

You would need to understand that it is a lot easier to code a CPU-Mining botnet than a GPU-Mining botnet, since a lot of people don't have AMD/Nvidia GPUs.

Recently, during this year, we have seen a game, Watch dog being infiltrated by botnets, used for mining.

Then there was Ads on Yahoo, doing the same thing.

What, apart from AV programs, and 3rd party firewalls, can detect and stop these botnets? Monitoring tools etc.

Well, those softwares are usually useless now, since they attempt to mine on your cpu, so if you're idling your pc and for some reason the cpu fan is spinning very quickly, then you need to check what's going on.
Also, check the CPU usage on task manager.
