Gigavps is a good guy - 2 successful hardware purchases.
In addition, pirateat40 conducted a decent size successful transaction for me.

I am thinking installing logmein hamachi, so I can access the rigs remotely. But I am having problem installing hamachi on Linux.
Is hamachi even available for linux? I use NeoRouter ( http://neorouter.com/) because it is cross-platform.

The not-quite-right reverend Satoshi Jones Nakamoto extends his open arms and welcomes you to the first day of your new life in The Bitcon!
Please enjoy the Kool-Aid, feel free to share it with your friends, family, and neighbors, we're always mining more. Ask any of the deacons for help, just avoid eye contact with them unless you actually want to be molested. Asking "What's that smell?" is discouraged as it only gets worse once you know how it's made.
Enjoy your stay and remember "The greatest thing about nothing is that it lasts forever." - From the "Thoughts of Reverend Nakamoto"

So if I understand correctly, the first seven steps (not including step 2) are like this: SHA256(SHA256(0x00 + RIPEMD160(SHA256(nonce))))
Yes except to say it is SHA256 of the nonce would confuse someone who didn't already know what you were trying to say. More accurately it is (steps 3 to 7) SHA256(SHA256(0x00 + RIPEMD160(SHA256(public key)))) Put all together: base address = 0x00 + RIPEMD160(SHA256(public key)))) checksum = left 4 bytes (SHA256(SHA256(base address))) full address = (base addres)s + (checksum) Makes more sense. Thank you.

Yes. Although if you want to get into the weeds generating a single address is a "little" complex (not sure what Satoshi was smoking ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) ) 1. Start with a 256 bit nonce (cryptographically secure pseudo-random number). 2. Use ECDSA to generate a corresponding public key. 3. Perform SHA-256 hash of the public key 4. Perform RIPEMD-160 hashing on the result of SHA-256 5. Add network byte in front of RIPEMD-160 hash (0x00 for Main Network) 6. Perform SHA-256 hash on the extended RIPEMD-160 result 7. Perform SHA-256 hash on the result of the previous SHA-256 hash 8. Take the first 4 bytes of the second SHA-256 hash. This is the address checksum 9. Add the 4 checksum bytes from point 7 at the end of extended RIPEMD-160 hash from point 4. This is the 25-byte binary Bitcoin Address. Of the 3 algorithms used SHA-256 is the most computationally intensive and it is performed 3 times in each key generation which is why I focused on that. The reason vanity gen can "only" try 20 million private keys (as opposed to 80 trillion) is primarily due to computational "cost" of the SHA-256 steps. Jebus that is complex. So if I understand correctly, the first seven steps (not including step 2) are like this: SHA256(SHA256(0x00 + RIPEMD160(SHA256(nonce)))) Yay? Nay?

SHA-256 is big. Far bigger than most people can comprehend. It won't be brute forced. Not today, not in a century. The pysical world equivelent would be like saying we might run out of matter in the universe if we keep building things. SHA-256 may be BROKEN due to cryptographic flaws but it won't be due to increasing hashing power.
Cool story. My understanding is that the blockchain uses SHA256, but the keypairs are ECDSA. Is ECDSA still 2^256, or is it something else? The private key is a 256 bit random number, the public key is derived from that random number. His discussion is still totally valid, since he is really talking about any 256 bit keyspace. It is even more valid since you don't have to recover the original private key, just any private key that corresponds to one of the public keys in the chain. Thanks, that clears it up for me.

For my positive contribution, this is the item that I am looking at to be my little controller, in case I happen to come across a farm of Singles http://www.e-itx.com/artigo-a1150.html It is a dual-core Via processor that is fully x86-64 compatible, in an awesome little enclosure. Comes with 4 USB ports, and has internal headers for more, as well as numerous expansion options. Not too expensive either! Those are pretty friggin cool! And new to me. I quickly eyeballed this one; http://www.e-itx.com/ve900-acd2.html It has the benefits of being slightly cheaper, inlcudes ram and ssd. Buttt, is lacking a lot of the features your posted one includes. Most importantly, there are no(?) included peripheral ports, namely USB, rj-45, etc. :/ Oh well, I will go get some coffee and brwose through some more. Thanks for sharing it!! cheers If you are into building your own enclosures, the Pico-itx motherboards are available bare, as well. The single core version of that is the P830, and the P900 is a drop-in replacement for it - same pinouts etc. Other versions are not fully x86 compatible, or don't support enough memory for larger OSes, but they are cheaper and lower power too.

U mad?
Yeah more authority and knowledge my fcking ass. Your attempt of insulting is rather amusing, i bet you're the shit in junior high.
Your post answered my comment perfectly. You cant STFU, i know how much you love cocks,
Would you mind please contributing positively for once? Although slightly offtopic, we had a nice discussion about supporting hardware that is ripe for some input. And you decide to barge in and say ITS ALL INVALID BECAUSE I CANT DO ANYTHING EXCEPT SPOUT MY OWN OPINION BLAH BLAH BLAH. I would rather hear stuff that appears to be a voice of reason, stating useful facts and contributing to a decent atmosphere instead of pissing in the pool.

I have added a new feature:
EMC now supports the use of Yubikeys for two factor authentication. Activating your Yubikey on EMC is a one time, one way process. Once it's active, it can not be deactivated. In addition to your traditional user name and password, you can choose to activate the Yubikey option by putting in an OTP in the Yubikey box under My Account. Once you do this, you will not be able to disable or otherwise remove your requirement for a Yubikey, and neither will an attacker!
Additionally, I have enabled the stale share counter under "reset." Resetting your shares will now also reset your stale count.
Is there a Yubikey software or do I have to buy a Yubikey USB-Key? Greetz NetworkerZ It's only available as a physical token, not as a software install like Symantec VIP.

Just get a PCI to PCI-E convertor, get something on the Bitcoin mining hardware list, even a 5770 is much better than any CPU and cheap at Ebay or even here where you can find some good priced graphic cards for sale.
over 1000 posts here and did not know you could do this. i can use my 6990s on a pci if i get the right adapter??? w00t! You would need the aforementioned adapter, but then you MUST ALSO have a powered PCIe riser cable. PCI provides 25 watts, and PCIe provides 75 watts - to be safe you need to make sure that monster card is getting its full 75 watts and not burning your adapter out.

I think it is entirely possible that the government MAFIAA Iran rich folks of this world might have access to SHA256 cracking monsters, and that the market for such devices is only just starting to be realized. Such a device could be re-purposed (with a little work) to mine coins when it isn't being used for cracking passwords legit purposes.

On a more serious note: if you're in the middle of fraking Amazonian Forest, a thin client might be the solution for you. The blockchain remains in the cloud and does not have to be downloaded and synced. Naturally, there are security implications to this approach as nothing in life is free.
Some allow you to control your private keys - this would be the best solution. Also, if you are mining it should work fine because of the low bandwidth requirements (for the most part) of a miner. I would be interested however to know how well this actually works over dialup.

It's a tragic legend unfortunately true. I live far away from fellow Linux hackers and the concrete jungles that sport 100 Mbps downlinks. To get to here you must to venture into the mountains and rally down dirt road to where the wireless signals come and go. If you ever feel curious enough to come out this far, don't be alarmed by the smell when you stop. It's just the fresh cow dung smoking off your exhaust. I've attempted to get started with Bitcoin before. Bit Faucet had graciously donated 0.05 BTC to me many months ago that I've been eagerly waiting for to appear in my client. And no, I haven't been downloading it all this time. In my fleeting interest I rightfully lost determination in downloading the entire block chain over my slow connection. Now the block chain is an order of magnitude larger. So determined again I've began redownloading the block chain. It's received roughly 200 MB so far (if you have a 10 Mbps connection, that's like waiting for 35 GB). In a few weeks it should be fully downloaded. Anyway, this is long enough. I just wanted to dispel the legend that dial-up is dead as disco. Or am I the only one that sees horses and code as part of a normal day? P.S. An idea for you entrepreneurs: a service that mails the block chain on DVDs to would-be users with impatience or slow internet connections. And I do mean mail and not IP over Avian Carriers. It's -20 C right now. P.P.S. As I finished writing this the transaction has showed up in my client with 400 confirmations. Perfect timing! Cool story bro. What state are you from?

Has anyone gotten Bitten to work? You're smart - you figure it out! But I'm not smart, and I haven't figured it out. ![Cry](https://bitcointalk.org/Smileys/default/cry.gif)

Additionally, I have enabled the stale share counter under "reset" but there is currently no way to reset it. I will be addressing that soon, but I wanted to mention it since I'm sure people will be a little confused as to why they can't reset their stale counts.
This is awesome. This pool just keeps adding sweet features.
