The Atoms have no power from what I have heard. No comparison between them and AMD/Intel desktop chips. Someone correct me if I am wrong.
I am currently mining with 3 atom based computers: Atom D510 (2 cores, 4 threads, 64 bit, 1.66GHz, 13W, running Ubuntu 13.10) Atom N550 (2 cores, 4 threads, 64 bit, 1.5GHz, 8.5W, Scientific Linux 6.4) Atom D525 (2 cores, 4 threads, 64 bit, 1.8GHz, 13W, Scientific Linux 6.4) With these 3 machines I am getting about 150~200 kh/s All of them are 3~4 year-old atom processors. These machines are performing their regular tasks ans I run the miner as a low priority process on them, so, not to interfere with their main tasks. Mining has no effect on power consumption on these machines, so, they are perfect for CPU mining. I am considering the option of updating the board of one of these servers to the new generation Supermicro boards including the Atom C27xx processor. Atom C2750 (8 cores, 8 threads, 64 bit, 2.4GHz, 20W). This processor should have 5.3x the CPU power of the D525 atom, and 1.5x the power consumption If you sent a payment and don't see any confirmations, it might be due to having no fee. I noticed my wallet doesn't have one set!
I have set a fee of 0.003 QRK. Maybe this is too low? If you (we  ) could get ~930 kh/S (= ~175 kh/s X ~5.3) I will place an order in the next few days! That is comparable to an AMD 8350 (I think), someone correct me here. Do you think these numbers would be accurate? Are there boards that hold multiple CPU's? Just checked, the latest Atom, from Dec 2012 has the following specs: Atom S1260 Dual Core 2.00 GHz 8.6 W
This wiki says they are dual core, not 8 core http://en.wikipedia.org/wiki/Intel_Atom_%28CPU%29 but they don't list the 2750???
Nevermind that. Re. Fee - It does sound too low, I would guess .01 or so, but am waiting for a reply to my question above. |

Has anyone come across the concerns raised by Mike Woods here in this thread? He said bitaddress.org is far from secure. Not a very long thread, would appreciate comments from those of you who really understand this area. https://bitcointalk.org/index.php?topic=399452.0A quote from that thread:
BitAddress.org is a great site, it had a good run, and it helped a lot of people for the last two years. But, it's far from perfect...
BitAddress uses only initial mouse position - which gives you about 20 bits that have fine entropy (and that mouse position is picked even if you don't move your mouse at all [not the case on my site]).
Having just 20 bits is enough to set up the seed, but not even enough for one private key created using true randomness, and you need new bits with good entropy for other addresses.
(Random numbers generated from seed have entropy equal to size of the seed - that's why they are called pseudorandom, and shouldn't be used for any security mechanisms: https://en.wikipedia.org/wiki/Pseudorandomness#Cryptography . Using pseudorandom numbers for storing your money is next to insane.)
Let's say you want to create 1000 addresses - that require around 1000*32*8 or around 500 000 bits of entropy, but instead you're using just 20 bits - so if you guess that 20 bits you'll have access to all 1000 addresses (which makes it worth for someone to brute force)
Other problems with BitAddress.org are:
- You are online while generating addresses - so you can't generate "offline" addresses, and also brings up the question if your browser or operating system is infected...
(- I also think that the site is not elegant enough with too much information that aren't necessary for average Bitcoin user (just my personal opinion)). |

I'd reccomend fx8320 or an fx6300 if you're building lots of rigs.  I'm all ears, why the 8320? (I'm just building one rig - and I am just gonna do it to support the network - but yeah, I'll take what I can get with Quarks). Suggestions? (I will use the rig for other things eventually, so probably get a DVD drive, 8GB ram but just on board video - I pay .28 KW/h for electricity, so video card mining is out.) CPU cooler is a must Thx Buy a 4 processor Xeon board. Don't you see the difficulty? Even that much firepower is NEGLIGIBLE. I think the network hash rate is 4K Mega+ Wow! Didn't realize they had them. Cost? Computer Models to buy? And As I said I want to support the network, so profit isn't #1 but breaking even would be nice. Thx For strict cpu mining, I'd say go with a dual xeon with intel ES cpus from Ebay, or get a dual westmere server pre built (you can sometimes find them for 250usd). You can get a board for 500 and add two 168usd 8 core cpus to it (ebay has em, search for intel es xeon 2011), and a 75usd ram kit, plus a psu and you're good to go. I reccomend the Corsair HX850 which lends itself well to gpu mining should you get a few nvidia cards for CUDA stuff (you can rent your gear for renders maybe? or just get 280X cards, each draws 200w if undervolted and nets you decent income even with high power costs). Bad news are that these kind of systems consume several hundreds of watts. In Spain (and all of Europe in general) electricity costs about 0.35 USD/KWh, so these systems are not profitable at all. I am considering options like the recent Atom series C processors. Yo have 8 full cores (no HT) with 64 bit with a mere 20 watt consumption. The board (including the processor) is priced about 400 USD: http://www.supermicro.com/products/motherboard/Atom/X10/A1SAi-2750F.cfmYeah, that is the problem! I pay .28 KW/h and that is huge. The Atoms have no power from what I have heard. No comparison between them and AMD/Intel desktop chips. Someone correct me if I am wrong. If you sent a payment and don't see any confirmations, it might be due to having no fee. I noticed my wallet doesn't have one set! There is a setting for it  That is essentially what I said. I was letting him know that might be the problem. (Hence the word "set") What is the recommended setting these days? I should set it just in case. |

It's certainly beautiful... I sure hope you are what you say you are Mike.
I downloaded the chrome "web page complete" and while running it locally, it let me do the mouse movements just fine but wouldn't let me go to the next screen upon generation. Oh well.
The more I think about it, the more I really think you need to make the site into a downloadable package that we can use as a portable app... It still seems too easy for the browser to report the priv key back to you after an offline generation. A cookie could store that and be told to report it at next page load, couldn't it?
I was looking out for the community when I said what I said and I think Mike knows that. Of course someone could write something in the Java to do what they want. A program does what you tell it. It doesn't have to send things back, it could create Private Keys that it is told to. I'm not accusing him though (I'm saying to be careful and have someone look at the code), perhaps he is bringing up a VERY important issue regarding those initial seeds not having the required entropy for truly random private keys and that is worrisome. That needs to be looked at. But, so does the code here. |

How many connections should I see if my port is forwarded correctly? Even with my port forwarded BTC QT wallet, I only sometimes see 9 connections. (Usually 8 and that is bad)
My Quarkcoin wallet is showing 15 active connections. I have no problem receiving payments, but I ordered one transfer 20 hours ago and I am still waiting (0 of 6 confirmations). Do I have to open / redirect any port in particular in my NAT / router? José Antonio Looks like yours is open. I found this "Quark uses 11973 Network port. Please open port 11973 on your router and post your IP there." here: http://altcoins.com/qrk-quark-super-secure-cryptographic-coin.htmlNot sure if that is right. Anyone? |

Thanks ivanlabrie, bit.craft and dE_logics for the information. I'll check out what you said ivanlabrie. bit.craft - electricity here in Germany is like .25+ cents - expensive. Perhaps the Xeon's lower wattage is a better decision relative to the AMD's?
dE_logics - The difficulty may be high but that doesn't mean there are lots of miners out there. The difficult is a bit skewed due to the multiple algorithms used (I have heard). And, being that we are hitting the 247+ million mark of coins mined, it is likely the number of miners fall off.

With due respect lucari, i am no expert but this sounds like it can be a very dangerous feature.
Easy man in the middle, hack, etc. - Can change addreses and then divert funds if they are used like that.
The accounts have trade dates and a hacker would just need to monitor activity and plan accordingly.
That is true, but all the site is running on SSL certificates, which will preclude man in the middle attacks. Hacks are always an option, even if i did my very best to use my 15+ years of web developing and sysadmin experience to secure the servers as much as possible. What would make you feel more secure? I can always add it. BTW, big update: you can now automatically import your transactions from Bitstamp! Vircurex is next  You obviously know more than me, was just putting it out there. Wow again with the features. Ps - I PM'd you the info you asked for yesterday. Thx |

Update! Now you can save all your receiving addresses for each coin for quick reference!
I will take care of the other issues (charts somehow) in the next days! Thanks for all the support!

Hey guys, with all due respect to Mike, he registered here Yesterday.
His code needs to be thoroughly looked through by the community before you go using it.
Most of us are not coders and open source is nice, once you know it is safe.
And I just checked - Mike opened his Git Hub account yesterday as well!
DO NOT USE this software until it is checked!!!

The company just emailed me back regarding the addresses and names:
We own both buildings 64 Dickenson Road is our Accountancy firm. You can google this.
It is a family run business, first name Mohammed is common, middle names are different.
Now, I doubt it is a multi year in the making Family scam! LOL |

I don't understand why anyone pre-ordered... did anyone actually read the technical papers they posted? https://alpha-t.net/wp-content/uploads/2013/12/Scrypt_ASIC_Prototyping_Design_Document.pdfSomeone please correct me if I'm wrong, but if you go to the last page, it says right there that their two projected speeds for their two models are 510KH/s and 2 MH/s. NOT 5MH/s and 25MH/s. So worst case scenario you're getting scammed, best case scenario you're getting less than 1/10th what you paid for... I believe you are looking at the hash rate for one chip, each running 128 cores at 600MHz which puts out 510KH/s. (1/2 MH/s) Each chip is using up 5 watts, they state 100 watts for the 5MH/s Viper Miner, so that probably means it has 20 chips (100 watts). 510KH/s X 20 = 10,200 KH/s. That is 2X the stated amount of 5MH/s so I must have done something wrong! As that is too much. Perhaps it just has 10 chips but the watts would be half the said 10 and I'm not sure where we could use the other 50??? Here is the answer: http://www.youtube.com/watch?v=69P2RHG2pIA&t=02m28s |

Well that's nice for you to not have to worry about money and be able to gamble with it so recklessly. Most here aren't in that position.
I have made a very tidy sum mining and trading BTC, LTC and PPC. I haven't lost a penny on any get rich quick scams though So I'm guessing my overall return % is far greater that yours.
I hope people read what you just posted and see the mindset and thinking it takes to "invest" in this. By all means recklessly gamble your way through life. But anyone here who plays blackjack will know a reckless player no matter how lucky will eventually lose his shirt to the house. You may be able to afford to do that. Most people here can't.
You are missing a bit of my point. First - I'm not reckless. If I was reckless, would I be so in the green? Think about that. You think I'm just "lucky"? I spend time researching and use intuition to a great length, that last part is hard for people to grasp. Hence my rational and such comments above. I guess I can't argue the gambling part, but any of us are in the same boat here. My point is in people coming on here and telling those that have bought of the risk we are taking. No Shit, we get that and have been hearing that for a long time. It almost seems like you think we don't know what chances we are taking. Are you here to rescue us, or is it the other way around, since you like to use the words like "recklessly" to label something you can't grasp? As I said, I live a very simple life, I don't make much money at all. 1600 or so Euro for the 5MH/s unit is a lot of money to me, but it is coming from profits. That isn't exactly "reckless". You can't put us all into a box. Brother, I think you're missing my point. Not everyone is like you. You've been around a while, grown profits, banked some and invested others. That's good, absolutely the way to play this and I commend you for that. BUT there are going to be a lot of people putting this on their credit cards and crossing their fingers. Remember how many people came crying to this forum when Payonix scammed them? Most people taking this risk are doing it in the hopes of massive profits. They WILL NEVER SEE THEM. In fact they will be lucky to ever see a working product. This needs to be pointed out. Once all the facts are on the table then by all means make an INFORMED choice. But don't roll the dice and hope for a six. C'mon man you really think I can't grasp this? Of course I can and on my risk scale I think reckless is being generous. Deluded may be more appropriate. You say you research. Tell me five CONCRETE and VERIFIABLE FACTS about this company? If you can't I would say that it is truly reckless to invest. I don't think that's an unreasonable conclusion. There is really no point going around and around on this. I wish you the best as I would hate to see anyone get taken for a ride. If it pans out I'll be the first to applaud your success. But in the long run people who play with fire in this way will get burned. Brotherman - Fair enough. I can totally agree with the first two paragraphs above! I was more defending me. Point taken. Regarding my "grasp" comment - I was purely talking about using intuition to guide myself in decisions. That is something most can't or won't grasp. I mix it with logic. To help others out, I'd still like to answer your question - regarding concrete facts. I'd like to add, my concern with this venture is not with it being a scam, rather, as with all the other companies who have come before (minus KNC to a large degree), they haven't met the deadlines. I don't have 5 concrete facts about the companies in question, but I never do. As I stated I do research and use my intuition. The latter is my final decision maker. I'm right way more than wrong using this method. I also haven't done background checks on the people running the companies, but I've looked into the companies. A few concrete facts and points of interest: 1 - Alpha Technology - The big unknown and a worry to a degree (I'd like more info). A new company - I think they started in April of last year! 2 - Dexcel Designs - Great news - They are a reputable company that has been around for 13 years or so. And they state the partnership with Alpha Technology on their website - http://dexceldesigns.com/news_events.html They must clearly be doing something with Alpha Technology and with the promised updates and transparency, I am not on high alert here - but still cautious. 3 - This thread was started by Alpha Technology on October 19th. Deposit payments (not full payments) started being accepted yesterday, that is around 10 weeks after first mention. Not a huge confidence builder but at least we can say there has been some planning, communication (there has), followups, etc. And related - next point 4 - Alpha Technology - Moving away from the 100% pay up front model to 30% deposit model. This limits our risks in a few ways and is a nice change. Most notably the CEO, Mohammed Akram, has made it clear that we need a transparent process along the way, with videos, updates, etc. As mentioned here - http://www.coinsigner.com/Blog/alpha-technology-takes-pre-orders-for-litecoin-asic-miners/ If the final payment is 8-10 weeks before delivery and we have a deliver of Q2 or Q3, that means we can conservatively say we expect 4 plus months of updates before final payment. That is a long time in this process. I just don't see it being a complete scam. Why do all the work (or fabricate and lie about it which is tough to get away with in this field)? That said, I will be sure to make my last payment via Pay Pal (Credit Card) to add some security to my purchase. Hopefully that option doesn't vanish! IAS |

I'm not sure if this was asked before. By the time they deliver the units, wouldn't the difficulty rate be at a point which would render the 5mhs or 25mhs you're getting useless?
The asics will not provide and exponential hash rate increase like we've seen with sha-256. In fact GPU's will be able to compete as far as hashing power goes, but the Asic will win on less energy consumption so the electric bill wont be so astronomical. ^-- This is the best reason for these machines. If I can cut down from using 100amps of power and get the same--even more--hashrate.. I'd be super thrilled. Yeah great at what expense though? That is a hefty price to pay for a cut in the energy bill, upfront, and who knows where the price will be next year. If I examine it purely from an electric bill standpoint, the unit would pay for itself instantly as soon as it began mining. How could you not see the benefit? Even if the machine only mined at half the estimated speed and took up 1,000watts, it's still ahead of the game. At least for me. I use scryptmining to pay for its electric bill, and to still provide profit. Something like this is a benefit, despite the cost. You are all assuming that the company will deliver and will stand behind their promises. If they do deliver then yea, you will double your profit because you won't pay astronomical electric bills. On the other hand but you are paying upfront 2-6 months in advance and that money isn't mining while you wait, meanwhile you could purchase GPUs and start mining, and by the 4 month mark your rig will have paid for itself even with the electric bills. Keep funding them with your money for a promise that doesn't even have such a good return/risk ratio  Such is the gamble. Speak with your wallet. We get it, it is a no for you. It is a yes for many of us. We are taking the chance. Being in Cryptos is a HUGE chance anyways for most people, getting into ASIC SHA256 mining is a chance on top of that and now into Scrypt mining (the FIRST one), is an even huger chance. I like the chance. I like being a part of history, regardless of the results. Such is life. Well you are here for the gamble and the thrill, not for making sensitive decisions. My post was about sensitive decisions. Try not to manipulate my words. I see English is not your first language, but no excuse for manipulation of what I said. Taking a word out of what I say, does not mean my perspective is based on it. Good luck to you and I hope you make a sensible decision. But don't forget the heart and intuition... |

Looks like you updated the dashboard. Nice! I like the pie chart breakdown of holdings.
I also liked the price following of the Cryptos. Is there room for both?
Really doing great work!
