Hey,

Want to sell 4.5 billion ISK.

Prices:

1 billion ISK - 5.5 BTC
1 PLEX - 2.8 BTC

Cheaper for multiple orders!

Obviously it's on TQ. Can give it as ISK (but more risky for bans), ships or whatever else as long as it's FAST (don't ask me to grab loads of Tritanium ore and haul it 30 jumps).

Would also accept somewhere in the region of 130 MTGO Tickets.

Reikoku.

Selling the five GPUs stated above. I am based in the EU.

First non-lowball offer takes them. Looking for at least 200BTC.

If I split them, you're paying shipping.

Buyer pays first unless very trusted. Bitcoin payment only.

Used. Looking for $180 or 45 BTC each.

EU-based. Can ship to anywhere in EU for $10 or 2.5 BTC.

Can get some pics soon, I'm out of the country at the moment.

Boxes are there, warranties haven't been registered and I've got the cards.

Trying to sell 2x XFX 5870 with boxes, they've been run for a month at 933/275 and got me about 430MH/s each. Asking 18 BTC each plus shipping.

Trying to sell 2x XFX 5770 with boxes, they've been run for 3 weeks (don't remember OC) and got me about 210MH/s each. Asking 10 BTC each plus shipping.

Warranties not yet registered so you can probably register those yourselves. Not 100% sure how this works.

1.11 BTC each. Buy 4 get 1 free (5 for 4.44 BTC).

In station delivery so you're far less likely to get caught (CCP monitors contracts) - usually within an hour if I'm awake, only waiting for 2 confirmations before delivering.

Only 20 15 left.

Like the title? Left-liberals seem to have this view with most forms of property. They believe that if you have two houses, two cars or twice as much money as most other people, then if you find somebody who has none, you owe him something.

Their argument goes a little something like this: "Your marginal utility from that second house/car/hundred thousand dollars is far less than the utility which would be gained by that person from it, therefore you owe him something.

Well, I'm going to propose that to them with another possession they might have two of, that some people have none of:

This is a kidney, it's a well-known fact that you can live with only one of them, but you probably have two nonetheless. As you're a left-winger, can you please explain to me why:

• It is morally wrong for me to make somebody sleep rough because I believe my right to the 14th bedroom of my mansion (I wish) is greater than his.
• It is morally acceptable for you to make somebody die because you believe your claim to your kidneys is greater than his.

This definitely passes the marginal utility test above. This guy is going to die if you don't give it to him, not just have to go without satellite television. You have approximately a 1% chance of developing end-stage renal disease, so his utility outweighs yours by at least a factor of 100 to 1.

Why are you not advocating forced redistribution of health?

Either you must accept that our claim to our own property is greater than the claim of others who so desire it, or you must accept that your ideology is incoherent, or you must all go and give a kidney away. Your choice.

[75 GH/sec] MineCo.in - LP,EU Server,SSL,JSON API,0% TAX <-- Not Sticky
[~60 GH/s] ozco.in - 1month birthday bonus - see inside <-- Sticky
[50 GH/s] Ars Technica community mining pool, 0% fees! <-- Sticky

Thought maybe it was because the sites were reporting inaccurately on their threads, so checked sites...

MineCo.in: 73 GH/s
ozco.in: 62 GH/s
ArsCoin: 62 GH/s

MineCo.in has consistently hashed faster than either of those pools, but was un-stickied today, can a mod/admin clarify?

Due to the sheer amount of controversy this has caused, I've decided to shut it down.

I don't think that penny auctions are a scam, but I do accept that there are far too many ways for me to have deceived people in the way this one was operated.

I thought long and hard about refunds and how best to do them, the doubling each refund above was appealing, but it didn't allow me to give out the 11 BTC which was what the winner had been promised.

I'm going to refund every bidder except the most recent with 0.25 BTC, and send the winnings of 11 BTC to the most recent bidder (1AQDgdT6Jmu642wVCF8ayPfdKfNghnfLzA). This means that the most recent winner will be paid 11 BTC, the rest will get their bids back and my losses are capped at 11 BTC.

BlockExplorer links for refunds:
Bidder 1 - Link
Bidder 2 - Link
Bidder 3 - Link
Bidder 4 - Link
Bidder 5 - Link
Bidder 6 - Link
Winner - Link

This has been a learning experience and although I'm down 11 BTC, I think I've gained some knowledge about the reaction of the forum to penny auctions, some of the weaknesses in it which are very hard to do securely, and how to better trade in future. For this, I think it's a fair price to pay.

Hopefully it will also show that I'm not a cheap profiteer and I'm not going to abuse the Bitcoin community which I enjoy being a part of. I was just trying a new commercial model and the resounding reply was that it doesn't work

If the winner wants the Radeon 5830, they can send me 12 BTC back (as originally said) to cover shipping anywhere in the world, and I'll send it to them.

I've found a great supplier of market anarchist flags, and as Bitcoin has a strong Libertarian following I figured I could offer these to the community.

Market Anarchist Flag


5' x 3': 4 BTC.
3' x 2': 3 BTC.

Gadsden Flag


5' x 3': 5 BTC.
3' x 2': 4 BTC.

These are made of a high-quality 200D polyester and come with gromits for easy attachment to a flagpole.

I can offer 10% off on orders of 2 or more units.

Price includes shipping to anywhere in the world.

[0.5 BTC per time unit]

This is a question I get asked relatively often, so I'm going to explain it here and hopefully this can be a useful reference to help people understand two things:

1. Why other people pool hopping is a problem for you (a 24/7 single pool miner).
2. Why proportional pools, not pool hoppers, are the fundamental issue.

First of all, we're going to assume that there is a proportional pool called Pool A, which mines at 90GH/sec without our miner.

Now, we have a miner, let's call him Bob, he runs a 10GH mining operation and he's trying to work out why hopping is an issue. To do this, we're going to make the numbers easy to work with. One block's regular length will be defined as 10 difficulty, which under normal circumstances (zero hopping) will equate to 10 units of time.

So, if Bob statically mines on Pool A, and nobody else is hopping, he should make approximately 5BTC (10% of 50BTC, as he's 10% of the hash rate) every 10 units of time.

0.5 BTC per time unit is Bob's expected yield.

Now let's see what happens to Bob if 50% of the pool hops after 5 time units (this is circa optimal). This means the pool will do the first half of the block at 100GH/sec, and the second half at 50GH/sec. In this scenario, Bob will be 10% of the pool for half of an average block, and 20% of it for the other half.

This means that in the first half he will earn 2.5 BTC, and in the second half, he will earn 5 BTC (20% of 25 BTC). On an average-length block, we can see that Bob is not negatively affected by hopping as the block will take 15 units of time, but he will get 7.5 BTC, still 5 BTC every 10 units.

From here, it's hard to see where the issue with hopping is, but we have to explore different length blocks to better understand the issue. Let's say, as happens in real mining, that instead of all 10 difficulty-unit blocks, we have a 5 unit block, and then a 15 unit block.

Without hopping, Bob will be 10% of the pool for 20 time units, and will make 10 BTC, or 0.5 BTC per time unit.

With hopping, Bob will earn 5 BTC from the 5 difficulty block, as the hoppers won't hop and he'll keep being 10% of the pool for the whole thing, this will be 1 BTC per time unit.

From the second block, he will earn 1.66 BTC from the first third of the block (1/3 of his 5 BTC for the block), and then 3.33 BTC for each of the second difficulty-thirds of the block. This totals out at 8.33 BTC, but this block will have taken 25 units of time to complete.

In case you didn't follow the maths.

First third - 5 difficulty - 100 GH - 1 diff:1 unit time - 5 units time
Second third (after 5 time units) - 5 difficulty - 50 GH - 1 diff:2 unit time - 10 units time
Third third - 5 difficulty - 50GH - 1 diff:2 unit time - 10 units time

This means that he's made 13.33 BTC in a total of 30 units of time for the short block and the long block, which is significantly lower than his expected BTC/time unit yield.

This return is only 0.44 BTC per time unit. This is 12% lower than he'd normally get!

On a longer block, it's even worse returns than this, and deviates even further from his expected yield, but a shorter block doesn't make up for it as the hoppers won't hop on those. Doing the maths for a 25 difficulty block, a 2 difficulty block and a 3 difficulty block, Bob would make 19 BTC in a staggering 50 units of time, which would be more than 20% below his expected 25 BTC.

If there was no hopping, these 3 blocks would have earned him 15 BTC in 30 units of time.

Obviously this is based on a huge proportion (50% of the MH/sec) jumping, which isn't likely right now, but the number of people using hopping techniques is only going to rise, and any loss due to this should be unacceptable to a miner.

But don't complain at other people for screwing you because they're pool hopping. You facilitate them doing it, it's their right to do it, you're screwing yourself. If you offered someone $10 an hour for a 5 hour shift or $7 an hour for a 10 hour shift, they'd take the 5 hour shift. This is what the hoppers are doing by maximising their own returns.

The answer is better pools, not calling people out for doing something they have a right to do.

tl;dr: By using a proportional pool 24/7, you may as well be paying a significant (up to 12%) fee.

I'm somewhat interested in writing a miner but I have no idea where to start.

I know a few programming languages (Assembly, C++, Perl) and I'm reading into CAL, but I don't actually know where to get information on fetching, processing and returning work.

Can anyone help me out with some sources?

[- Odds are subject to change, nothing is final until I *PM* you odds. I will try to keep the thread up to date but obviously things can change when I'm asleep or out or whatever.]

I figured no one's doing it, and I can do it (used to work at a bookie) so I'll shoot for it.

How it Works
- You PM me the bet you want to make and your receiving address, and wait for my reply confirming the odds and the payout if you win.
- I will generate an address for you to send to, and you will send me the BTC you want to bet.
- I will generate a PM for you confirming your bet, with a reference number which you can quote when you win.
- You are anonymous, but I certainly won't complain if you post here and vouch for me.
- Odds are subject to change, nothing is final until I *PM* you odds. I will try to keep the thread up to date but obviously things can change when I'm asleep or out or whatever.

Rules
- Maximum bet 1 BTC. I don't want to go broke and don't want to make anyone broke.
- Minimum bet 0.02 BTC. Don't want to be hit with a bunch of microtransactions and not be able to pay fees.
- Winnings must be claimed within 30 days of a bet being won.
- If there's a bet you want to make which isn't here, just ask for some odds and I'll offer or not.
- You can place aggregate bets, for example a bet at 2/1 and one at 3/1, if both win you get the combined winnings (6/1) but if only one or neither wins, you get nothing.
- It is your responsibility to confirm that you are legally allowed to bet.

The Odds
Odds are given in the English format of X/Y. You will bet Y, and if you win, you get X back plus your bet of Y. For example, if the odds are 7/2, you can bet 0.2 BTC. If you win you get 0.9 back, 0.7 plus the 0.2 you bet in the first place.

For MLB, NBA, NFL, Ice Hockey, Soccer... whatever, just ask for odds and we'll work something out.

[Welcome to the Bitcoin Virtual Currency Exchange]

Welcome to the Bitcoin Virtual Currency Exchange

I realise that I've already created a number of threads for trading to individual currencies, so I'm trying to combine all of those threads into a single place of trade.

Here, I will buy and sell several virtual currencies for Bitcoin, meaning that you'll always have access to the currencies you want, when you want them. Right now, I'm dealing in the following virtual currencies:

• Eve Online ISK

• Second Life Lindens
• Namecoin

The prices are entirely based on the current USD to BTC exchange rate of $17.50 to 1.0, and they will fluctuate based on that exchange rate, as well as the varying values of virtual currencies.

Currently Buying Currencies At:
Linden Dollars - 5,100 L$ for 1 BTC
Eve Online ISK - 900 million for 1 BTC
Namecoin - 40 for 1 BTC

Currently Selling Currencies At:
Linden Dollars - 4,400 L$ for 1 BTC
Eve Online ISK - 650 million for 1 BTC (1 PLEX for 0.7 BTC)
Namecoin - 25 for 1 BTC

If, for a specific currency, there is a large gap between my buy rate and my sell rate, it is because right now I either have a lot of the currency in stock and as such don't need much more, or it sells very slowly.

[Mom's Basement Mining Contracts]

Mom's Basement Mining Contracts

What is This?
I'm going to be selling mining contracts (not based in my mom's basement, sadly) on dedicated mining rigs. These rigs are built using high quality branded products, and will be GPU mining via the pool of your choice directly to your wallet (if you don't have any account details, I can set them up to mine for you on Eligius, my pool of choice, as it only needs your receiving ID).

The main reason I'm doing this is to fund an expansion in my own long-term mining capabilities, not to make a huge wad of profit from you. Because of this, I'm not going to be charging the high fees that are currently ongoing in the contracts market. This does not mean you will have to wait for your mining operation to come online, I have rigs already mining and assuming I have the capability online right now, they will be shifted to your account upon purchase of services to give you an instant startup. Obviously, if you order more than I have in place, I'll let you know what the delays should be.

A lot of mining contracts out there don't seem to be profitable, but these (the MH-800 and MH-1200) are going to kick that trend and offer decent outcomes for you even if you're just looking for pure $ profit (obviously, this depends on a decent GH/sec to dollar ratio).

Advantages of Contracts
Advantages over buying Bitcoin on the market are:

• No risk of getting stolen bitcoins, all BTC are newly generated
• No risk of getting your money stolen by a scammer
• No commission fees, market depth issues or exchange delays
• Output based purely on difficulty, not exchange rates

There are also advantages over buying your own mining rig, mostly boiling down to:

• No chance of downtime issues or damaging your components
• No need to deal with electricity costs, noise, heat etc. just pay $ and get Bitcoins
• Don't need any technical knowledge to get the best out of it

Purchase Information
These contracts are going to run for a minimum of 13 weeks, but I'll allow you to extend your contract for an extra four weeks at the same price per week as the first 13 at any time before it expires. Payment will be in advance 100% (for 13 weeks) via bank transfer, Liberty Reserve or Bitcoin.

If you want to pay in Bitcoin, we will discuss the price at the time of purchase, but it will probably be done at or around Mt Gox last price.

Pricing & Profitability
$ Output is calculated at today's (15th June 2011) difficulty of 877,227 and today's Bitcoin price of ~$20. At this rate, you would get 0.00114 BTC per MH per day, or $0.0228 per MH per day. As difficulty and Bitcoin price are linked, the best we can do to calculate profitability is assume that a MH keeps around the same profitability (although the profitability of 1MH has definitely risen over the past month, which would work in your favour if it continues).

Contract Type	MH/sec	BTC/day	Price (1wk)	Price (13wk)	$ Output (13wk)	Exp. Profit (13wk)	Available
MH-400 I	370	0.42	$52	$676	$767.67	$91.67	Now
MH-800 I	740	0.84	$84	$1092	$1535.35	$443.35	1 Week
MH-1200 I	1110	1.26	$115	$1495	$2303.02	$808.02	1 Week

Obviously, none of these profit margins are guaranteed, they are simply a model at today's value per MH which could rise, fall or stagnate. BTC/day is based on today's difficulty, and is subject to change during the contract period.

Price Comparison
I don't like comparing this service to Vladimir's or Bitcoin Rigs', because we are all serving different markets for different purposes. Having said that, I feel compelled to compare simple 1GH/sec prices across the market for an easy glance. Check out all of the services and see what you want. This table is correct TO THE BEST OF MY KNOWLEDGE. If you spot an error, let me know.

Service	Vladimir	Bitcoin Rigs	alexdrans' 400	alexdrans' 800	MH-400 I	MH-800 I	MH-1200 I
Per 1GH/s/wk (US$)	$158.41*	$192.31	$144*	$135.50*	$159.46	$113.51	$103.60
Min Size	1GH/s	1GH/s	0.4GH/s	0.8GH/s	0.37GH/s	0.74GH/s	1.11GH/s
Min Length	4 months	3 months	1 month	1 month	3 months	3 months	3 months
Zero Variance	Yes	Yes	No	No	No	No	No

As you can see, I can offer some very flexible contracts in terms of GH/sec (three sizes to choose from) and also the lowest prices, alexdrans offers 1 month contracts, which seem to be attractive. Vladimir offers zero-variance and is a Limited company (I assume this means he can give you a VAT receipt if you're in the EU). We are all different services aimed at different customer bases.

* For Vladimir's and alexdrans' service, I have used the xe.com GBP to USD conversion rate of 1.62.

I have assumed Vladimir's month is 4.5 weeks or 31.5 days, and that Bitcoin Rigs' 3 months is 13 weeks.

FAQs
Admittedly some of these questions aren't really 'frequently asked', they're just ones which I think you might ask. If a question is frequently asked, or I just think it's a great question, I'll add it here.

Do you do shorter contracts/can I pay monthly or weekly?
Sorry, I'm not able to offer credit agreements. The only way you will be able to pay monthly or weekly is if you use a credit card to buy LR or Bitcoin and pay your credit card off monthly or weekly. I am also unable to offer shorter contracts, as the idea of these contracts is to forego the profitable short term mining to fund a long-term expansion in my mining capability.

What uptime do you guarantee?
I will guarantee zero downtime via the following mechanism:
- For each of the first 24 hours of downtime, I will add another hour to the end of your contract.
- For any hours beyond 24 of downtime, I will add two hours to the end of your contract instead.

Can I have shell access to my rented rig?
No. I can't offer uptime guarantees and shell access, and I can't risk one of the cards being overclocked to the wrong specifications. If you want me to run a specific miner or a specific set of options, or something other than Bitcoin (Namecoin, F@H, whatever), then I am willing to do so upon request (assuming it's not malware or illegal).

Can you offer zero-variance?
I could probably do this upon request for an extra fee of around 10%, but it's not a part of my mainstream plans.

Where is your flashy website?
I haven't made one yet, but it will come soon™.

What hardware equipment are you using?
My rigs run on AMD Sempron 140, AMD Sempron 145 and Intel Celeron E3400 processors, DDR2 & DDR3 RAM, 7200RPM SATA hard drives (USB flash drives fail often), XFX / Corsair Power Supply Units (650W/750W for MH-400 I and MH-800 I, 1000W for MH-1200 I) and XFX / Sapphire Radeon 5770, 5830, 5850, 5870, 5970 and 6970 GPUs. Most run open-case and no GPU cores run above 80C.

Can you guarantee hash rates?
Mostly your hash rates will be a little bit lower or higher than what has been specified (no more than 5% variance), but if I can only get 5830s due to the market, they could be a little lower. I will let you know before you pay if this is the case, and will discount your prices accordingly.

If you do get a very low hash rate (more than 5% below quoted, as there will always be variance) then you will be compensated in Bitcoins for the expected value. Please don't think this means that if you end up with 1102 on a 1110MH rig, that you're going to be compensated. Hash rate will be judged by the mining applications, not by any pool stats which are often inaccurate.

What software are you using?
My machines run regularly updated builds of Arch Linux, AMD Stream SDK 2.4, latest Catalyst drivers. I prefer the phoenix/phatk miner, but can use phoenix/poclbm or diablo if requested.

What customer support can you offer?
I can offer support via IRC (FreeNode), by e-mail or by the forums. I'm working on a web-based interface to monitor downtime, but for now we can use the mining pools' stats pages to monitor that (I use eligius by default, which has no registration and just pays directly to your wallet).

Who are your customers?
My customers have a right to privacy, and I will not be sharing their identities. Should they wish to comment on the quality of the service, that's their right, but they have no requirement to do so.

One thing that I like on this forum is the variety of things which I can offer and purchase from people via the market area. As you can see from my signature, I'm a bit of a Jack-of-all-Trades, offering mining contracts, shell scripts and currency exchanges.

My main issue is that despite my signature being fairly small (two lines on a decent resolution screen) I can't expand it, meanwhile some people's signatures are far larger (screen real-estate wise) but within the limits.

I think that on a forum, the best measure of a reasonable signature is vertical pixels, not characters, so I'd like to propose limiting the signature to say four or five line rather than by number of characters. In my opinion, this would be better for traders like myself, and would better limit the actual imposing signatures (those few with large images or a lot of lines).

Would like to know what other people think.

[Autominer 0.3.2.6 - New Interface Baby!]

Autominer 0.3.2.6 - New Interface Baby!

I decided to redo the thread from scratch to better explain Autominer. I felt that the old thread rambled a bit and didn't explain enough, so this one should be better designed to take care of the users' needs.

About Donate Mode

A few people were saying they'd like to donate but have no BTC up front, so if you want to, just edit common.lib (on v0.3.2.3 or above) and put the following line at the bottom:

donateMode=1

It will automatically give me 1 out of every 200 mining cycles (0.5% of your mining time). I will implement an option later so you can decide how much to donate.

This option is off by default, it's purely optional, and thanks if anyone decides to use it.

Download Autominer v0.3.2.6




What is Autominer?
Autominer is a bash script (technically, a set of bash scripts) written to automate the process of mining on a Linux rig. After a relatively short configuration time, you can just type a single command to start mining on all of your GPUs, in screen sessions for remote monitoring, with a temperature monitor and automatic pool monitoring and swapping in the case of downtime. Interested? Good.

And some history...

v0.3.2.6
- Bug fix of the checkphoenix.sh script (it was connecting to the wrong pool)
- Bug fix in screen settings

v0.3.2.5
- Added a 'countTarget' variable to change the frequency of 'successfully mining' updates
- Added a checkphoenix.sh script for diagnostic purposes
- Added better output to configure.sh when no workers are chosen
- Fixed a bug that was causing configure.sh to ask about donateMode for each GPU

v0.3.2.4
- Fixed a bug in configure.sh where it was writing Worksize variable to queuesize.
- Cleaned up configure.sh

v0.3.2.3
- Fixed a bug with the 'kill process' function.
- Cleaned up some text outputs.
- Added getting the CHANGELOG when using an outdated version.
- Fixed the loop function in the main program.
- Added 'donation mode' (optional, of course). To donate 0.5% of your mining to aid Autominer
development, just add 'donateMode=1' to common.lib. This will cause one in every two hundred cycles
to be donated.

v0.3.2.2
- Added support for PLATFORM in Phoenix.

v0.3.2.1
- Fixed a bug which caused pool switching not to work on machines with both monitoring modes enabled
if the downtime was picked up by GPU load first.

v0.3.2
- Added support for hashrate-based pool downtime detection in addition to GPU-load based, works even
if overdrive won't report GPU load (it's an issue for some people with risers) - needs XML RPC enabled
- Fixed a bug with downloading 'LATEST' file

v0.3.1
- Added experimental support for thejfk's getRate.py hack to display hashrate in miner window
- Rewrote the entire interface to use a single screen window, takes some getting used to

v0.3
- Added defaults files in order to avoid overriding a user's config upon update
- Added warning and disabled pool monitoring if GPU load can't be found (previously caused error spew)
- Added a stopmining.sh script which should look through screens and kill all Autominer screens
- Added detection for obsolete versions
- Added an experimental configuration script
- Removed version numbers from several script headers
- Moved opening the temps window to the main script
- Changed the temps window so that height corresponds to number of GPUs

v0.2
- Added status update to monitor where cards are mining and if cards are mining
- Added timestamps to output in main window

v0.1b
- Added support for phoenix failures, added workers

v0.1
- Got it working


What does Autominer need?
Autominer needs a relatively standard set of Linux tools, plus a mining program, those are:
tar - To extract the archive in the first place
wget - To check for updates to the package
screen - For monitoring sessions
xterm - To load the terminal windows themselves
phoenix-miner - To mine delicious coins!

To get this short list of tools (other than Phoenix, that's here in the forum) in the main distros is easy, fire up a command line and type:

Ubuntu Natty: sudo apt-get install screen tar wget xterm
Debian: sudo apt-get install screen tar wget xterm
Arch Linux: pacman -S screen tar wget xterm
Gentoo: emerge screen tar wget xterm

In addition, you need to be running X11 in order to take advantage of ATI Overdrive & multiple Xterm windows, and you need a few minutes to go through configuration the first time you run it.


So, how do I install it?

Well, download the tar.gz file at the top, then go to your favourite command line and navigate to where you put it. Do:

tar xvfz Autominer-x.x.tar.gz (where x.x is the version number)
cd Autominer
./configure.sh

Follow the instructions in the configuration script, assuming it works it will spit out two files called cards.lib and common.lib, with all the information you put into the script contained in them.


I'm running Autominer, how do I update it?

If your existing version is 0.3 or above, follow these instructions. If you're on 0.1, 0.1b or 0.2, you'll need to remove your existing Autominer & follow the install instructions as above. This is because 0.3 changed the file structure and the variable names, and is fairly incompatible with lte v0.2 config files.

Assuming you're running v0.3 already, simply download the .tar.gz and extract the files into your Autominer directory. This will not overwrite cards.lib or common.lib, as I have modified the file structure to preserve these files which contain your settings.


How do I *RUN* this beast?

First of all kill any miners you have open, then go to the Autominer directory and run ./startmining.sh /path/to/Autominer

Controls for the window:
F1-F6 = Windows 0-5
F7 = Previous window
F8 = Next window
Ctrl-a then a number = That number window
Ctrl-a then d = Detach screen (keeps miner running)


You have MH/S in your 'amm' window... how do I get that?

This technique relies upon a patch to Phoenix developed by thejfk, but it's relatively easy.

1. Open up a command line
2. cd to your phoenix directory
3. wget http://robertlacroix.com/files/phoenix-xmlrpc.diff
4. patch -p0 < phoenix-xmlrpc.diff
5. Send thejfk a tip: 1EhQ1dbeZnxs7wZKngegsHLheAjUK37k7m
6. cd to your Autominer directory
7. Edit common.lib, at the bottom write on a new line:

8. Start up your miner, the rest should happen automatically


And how do I monitor it over ssh?

If you want to open over ssh, do DISPLAY=:0 ./startmining.sh /path/to/Autominer

Connect to the screen using screen -x amm -p 0


So, what happened to the file structure?

Previously, whenever you updated Autominer, it came with a new cards.lib and common.lib, this meant you had to re-configure everything every time. Now, I've created files called cards.defaults.lib and common.defaults.lib.

These files allow me to define new variables without overwriting the variables you've saved in your configuration scripts. Obviously, you shouldn't edit the defaults files (they'll be overwritten when you update) but if you want to change something in there, simply copy the variable into cards.lib or common.lib and change it there.

Variables in cards.lib and common.lib OVERRIDE those in cards.defaults.lib and common.defaults.lib. The only time the defaults will be used is if something isn't defined in YOUR config settings.


Can I still manually modify the .lib files?

Sure can. Just copy cards.sample.lib to cards.lib and common.sample.lib to common.lib and modify. Don't edit the defaults, they will be overwritten when you update again.


Common Problems & Troubleshooting

Computer clearly mining but autominer won't connect to the display - Often caused by starting an identifier name with a number. Check your identifier names start with a letter.

[the poor in your country are going to be fine]

Dear left-leaners of all kinds,

I'm not an anarcho-capitalist, but I often see this ridiculous criticism of anarcho-capitalism that somehow if it were implemented, the poor would just starve and have no healthcare etc. So, let's do some maths based on some core assumptions that even you guys accept:

• 50% of the USA is left-leaning
• These people want the poor to have essential services

OK, let's assume for now that all evil right-wingers won't donate a cent, and that income is split approx 30/70 in favour of the right (this probably isn't true as many high-paid jobs are mostly practiced by left-wingers, but just to use ridiculous maths), so you have 30% of the wealth between all of you lefties.

Now let's assume you guys don't decide along with the right-wingers that you don't care about the poor, because you're better than us. Therefore, in the absence of government, you all agree to pay 'taxes' to provide essential services to those people (i.e. donate to charity). Let's say you all accept that 33% of your income is a fair amount, so we have 10% of the USA's GDP to spend on 'key' services.

Right now, this is somewhere in the realm of $1.4 trillion. Now, let's take a socialist country like the UK, and work out what $1.4 trillion (about £900 billion) could pay for. I'll multiply the budgets by 2.5, assuming that you're providing for the 50% of poorest Americans, as these services are currently provided to all of the UK.

You could pay for:
- The entire NHS service (free of charge healthcare which achieves a greater HALE than the US healthcare system) - £315 billion
- The entire state education service (free of charge education which achieves a reasonable global standard) - £200 billion
- The welfare state (provides up to $20,000 a year of welfare to the poor) - £290 billion

This comes to £805 billion ($1.3 trillion), so not only under tax-free voluntarism could you have free health & education for 50% of the population, but you could do it to a similar standard in education and 'better' in health & welfare than the current provision in the US.

This works on the ridiculous assumptions that you'd be as inefficient as the UK government and that you'd get no support from any of us evil rich right-wingers. Whatever the state of the world, if you lefties care as much as you say you do, the poor in your country are going to be fine no matter how evil we are.

[Mom's Basement Mining Contracts]

Mom's Basement Mining Contracts

What is This?
I'm going to be selling mining contracts (not based in my mom's basement, sadly) on dedicated mining rigs. These rigs are built using high quality branded products, and will be GPU mining via the pool of your choice directly to your wallet (if you don't have any account details, I can set them up to mine for you on Eligius, my pool of choice, as it only needs your receiving ID).

The main reason I'm doing this is to fund an expansion in my own long-term mining capabilities, not to make a huge wad of profit from you. Because of this, I'm not going to be charging the high fees that are currently ongoing in the contracts market. This does not mean you will have to wait for your mining operation to come online, I have rigs already mining and assuming I have the capability online right now, they will be shifted to your account upon purchase of services to give you an instant startup. Obviously, if you order more than I have in place, I'll let you know what the delays should be.

A lot of mining contracts out there don't seem to be profitable, but these (the MH-800 and MH-1200) are going to kick that trend and offer decent outcomes for you even if you're just looking for pure $ profit (obviously, this depends on a decent GH/sec to dollar ratio).

Advantages of Contracts
Advantages over buying Bitcoin on the market are:

• No risk of getting stolen bitcoins, all BTC are newly generated
• No risk of getting your money stolen by a scammer
• No commission fees, market depth issues or exchange delays
• Output based purely on difficulty, not exchange rates

There are also advantages over buying your own mining rig, mostly boiling down to:

• No chance of downtime issues or damaging your components
• No need to deal with electricity costs, noise, heat etc. just pay $ and get Bitcoins
• Don't need any technical knowledge to get the best out of it

Purchase Information
These contracts are going to run for a minimum of 13 weeks, but I'll allow you to extend your contract for an extra four weeks at the same price per week as the first 13 at any time before it expires. Payment will be in advance 100% (for 13 weeks) via bank transfer, Liberty Reserve or Bitcoin.

If you want to pay in Bitcoin, we will discuss the price at the time of purchase, but it will probably be done at or around Mt Gox last price.

Pricing & Profitability
$ Output is calculated at today's (15th June 2011) difficulty of 877,227 and today's Bitcoin price of ~$20. At this rate, you would get 0.00114 BTC per MH per day, or $0.0228 per MH per day. As difficulty and Bitcoin price are linked, the best we can do to calculate profitability is assume that a MH keeps around the same profitability (although the profitability of 1MH has definitely risen over the past month, which would work in your favour if it continues).

Contract Type	MH/sec	BTC/day	Price (1wk)	Price (13wk)	$ Output (13wk)	Exp. Profit (13wk)	Available
MH-400 I	370	0.42	$52	$676	$767.67	$91.67	Now
MH-800 I	740	0.84	$84	$1092	$1535.35	$443.35	1 Week
MH-1200 I	1110	1.26	$115	$1495	$2303.02	$808.02	1 Week

Obviously, none of these profit margins are guaranteed, they are simply a model at today's value per MH which could rise, fall or stagnate. BTC/day is based on today's difficulty, and is subject to change during the contract period.

Price Comparison
I don't like comparing this service to Vladimir's or Bitcoin Rigs', because we are all serving different markets for different purposes. Having said that, I feel compelled to compare simple 1GH/sec prices across the market for an easy glance. Check out all of the services and see what you want. This table is correct TO THE BEST OF MY KNOWLEDGE. If you spot an error, let me know.

Service	Vladimir	Bitcoin Rigs	alexdrans' 400	alexdrans' 800	MH-400 I	MH-800 I	MH-1200 I
Per 1GH/s/wk (US$)	$158.41*	$192.31	$144*	$135.50*	$159.46	$113.51	$103.60
Min Size	1GH/s	1GH/s	0.4GH/s	0.8GH/s	0.37GH/s	0.74GH/s	1.11GH/s
Min Length	4 months	3 months	1 month	1 month	3 months	3 months	3 months
Zero Variance	Yes	Yes	No	No	No	No	No

As you can see, I can offer some very flexible contracts in terms of GH/sec (three sizes to choose from) and also the lowest prices, alexdrans offers 1 month contracts, which seem to be attractive. Vladimir offers zero-variance and is a Limited company (I assume this means he can give you a VAT receipt if you're in the EU). We are all different services aimed at different customer bases.

* For Vladimir's and alexdrans' service, I have used the xe.com GBP to USD conversion rate of 1.62.

I have assumed Vladimir's month is 4.5 weeks or 31.5 days, and that Bitcoin Rigs' 3 months is 13 weeks.

FAQs
Admittedly some of these questions aren't really 'frequently asked', they're just ones which I think you might ask. If a question is frequently asked, or I just think it's a great question, I'll add it here.

Do you do shorter contracts/can I pay monthly or weekly?
Sorry, I'm not able to offer credit agreements. The only way you will be able to pay monthly or weekly is if you use a credit card to buy LR or Bitcoin and pay your credit card off monthly or weekly. I am also unable to offer shorter contracts, as the idea of these contracts is to forego the profitable short term mining to fund a long-term expansion in my mining capability.

What uptime do you guarantee?
I will guarantee zero downtime via the following mechanism:
- For each of the first 24 hours of downtime, I will add another hour to the end of your contract.
- For any hours beyond 24 of downtime, I will add two hours to the end of your contract instead.

Can I have shell access to my rented rig?
No. I can't offer uptime guarantees and shell access, and I can't risk one of the cards being overclocked to the wrong specifications. If you want me to run a specific miner or a specific set of options, or something other than Bitcoin (Namecoin, F@H, whatever), then I am willing to do so upon request (assuming it's not malware or illegal).

Can you offer zero-variance?
I could probably do this upon request for an extra fee of around 10%, but it's not a part of my mainstream plans.

Where is your flashy website?
I haven't made one yet, but it will come soon™.

What hardware equipment are you using?
My rigs run on AMD Sempron 140, AMD Sempron 145 and Intel Celeron E3400 processors, DDR2 & DDR3 RAM, 7200RPM SATA hard drives (USB flash drives fail often), XFX / Corsair Power Supply Units (650W/750W for MH-400 I and MH-800 I, 1000W for MH-1200 I) and XFX / Sapphire Radeon 5770, 5830, 5850, 5870, 5970 and 6970 GPUs. Most run open-case and no GPU cores run above 80C.

Can you guarantee hash rates?
Mostly your hash rates will be a little bit lower or higher than what has been specified (no more than 5% variance), but if I can only get 5830s due to the market, they could be a little lower. I will let you know before you pay if this is the case, and will discount your prices accordingly.

If you do get a very low hash rate (more than 5% below quoted, as there will always be variance) then you will be compensated in Bitcoins for the expected value. Please don't think this means that if you end up with 1102 on a 1110MH rig, that you're going to be compensated. Hash rate will be judged by the mining applications, not by any pool stats which are often inaccurate.

What software are you using?
My machines run regularly updated builds of Arch Linux, AMD Stream SDK 2.4, latest Catalyst drivers. I prefer the phoenix/phatk miner, but can use phoenix/poclbm or diablo if requested.

What customer support can you offer?
I can offer support via IRC (FreeNode), by e-mail or by UK SMS message. I'm working on a web-based interface to monitor downtime, but for now we can use the mining pools' stats pages to monitor that (I use eligius by default, which has no registration and just pays directly to your wallet).

Who are your customers?
My customers have a right to privacy, and I will not be sharing their identities. Should they wish to comment on the quality of the service, that's their right, but they have no requirement to do so.

[Welcome to the Bitcoin Virtual Currency Exchange]

Welcome to the Bitcoin Virtual Currency Exchange

I realise that I've already created a number of threads for trading to individual currencies, so I'm trying to combine all of those threads into a single place of trade.

Here, I will buy and sell several virtual currencies for Bitcoin, meaning that you'll always have access to the currencies you want, when you want them. Right now, I'm dealing in the following virtual currencies:

• Eve Online ISK
• Second Life Lindens
• Namecoin

The prices are entirely based on the current USD to BTC exchange rate of $17.50 to 1.0, and they will fluctuate based on that exchange rate, as well as the varying values of virtual currencies.

Currently Buying Currencies At:
Linden Dollars - 5,300 L$ for 1 BTC
Eve Online ISK - 900 million for 1 BTC
Namecoin - 26 for 1 BTC

Currently Selling Currencies At:
Linden Dollars - 4,500 L$ for 1 BTC
Eve Online ISK - 650 million for 1 BTC (1 PLEX for 0.72 BTC)
Namecoin - 16 for 1 BTC

If, for a specific currency, there is a large gap between my buy rate and my sell rate, it is because right now I either have a lot of the currency in stock and as such don't need much more, or it sells very slowly.

My OTC web of trust ratings can be found in my signature.
