CCMiner beginners guide - How to setup and use ccminer ...

part 3: down the NodeRed rabbit hole - resurrection (long)

so, now that i've got about 4 weeks of NR experience under my belt, i thought i would do a follow up and show a few new flows. plus, i've picked up a few new hardware add-ons. namely a Harmony Hub and a coupla Sonoff/Tasmota S31.
one of the new things i did was setup some global.variables i can use in any flow.
https://imgur.com/YFJEwRd
1] is pretty obvious, does my bayesian sensors think i'm home/not_home, and then save it to a global.variable.
2] reads the MQTT for my S31 power monitor on my dumb TV. if it's > 100, then the TV is ON, <= 99, then TV is OFF (or in the process of turning off). then set a global.variable for on/off.
https://imgur.com/mcuS1Vk
3] i changed the day/night temperatures to global.variables.
4] this one gets the current volume level of my Sonos and then stores that to a global.variable. (get to why further below)
5] this one i talked about in another post here: https://www.reddit.com/homeassistant/comments/abvqup/device_tracker_with_unifi2mqtt/
okay, so now that i know if my dumb TV is on/off, then i can add it into my "away" (and "bedtime") flow. that gray one on the bottom right is using the HarmonyHub control node to fire the power toggle. (which i'll get to further below) plus it'll stop my Sonos, if it's playing.
https://imgur.com/nerbMv3
also you may notice the "alexa TTS" one, that's a subflow, which is a bit of reusable flow, you can put anywhere you want it. this one picks a random number between 1 and 10, then alexa TTS plays the corresponding message.
https://imgur.com/bLtBlaD
this was also my attempt to get alexa to say "aaaf-firmative" like newt in aliens.
https://imgur.com/cUnG1IE
doesn't really work, but i'm determined to make this happen. gonna have to figure out the proper phonetics of it. then i'm totally gonna get her to do a stutter like max headroom on one of the other responses. but, my ultimate goal is to get her to do "twiki" from buck rogers. beaty beaty
anyways, i've also added that subflow to all my switch on/offs. along with an MQTT log.
https://imgur.com/SnpAnW8
now for some of the new stuff...
here's a sleep timer. if i'm listening to music in bed, i can activate this with "alexa turn on sleep" and what it does, is it takes the current volume level of my Sonos, stored in a global.var, stores it in a flow.var, then subtracts 1 every minute, until it reaches zero. if the volume is at 30, then it'll be 30 mins until zero.
https://imgur.com/7QmbY2S
once it reaches zero, it stops the music, sets the volume back to the original state (ie: 30) and then turns itself off.
there's an issue when you use something like a Harmony Hub to turn on/off dumb devices via input_bool, or switches, or lights, etc.: that once you turn it on via NR, HA, HHub, Alexa, etc., then HA thinks it's on. if you then turn it off via the device remote, HA won't let you turn it on again, because HA thinks its already on.
so, i had to use a script and a "dummy" input_boolean. by dummy i mean, that i do not care, and will not EVER care, what it's state is. on. off. whatever. won't need it. it just needs to be there for the script to work.
input_boolean: mac_x: game_x: candles_x: tv_x: 
hide them from emu_hue, cause Alexa doesn't need to see them either.
emulated_hue: host_ip: 10.xx.xx.xx exposed_domains: - input_boolean - script entities: input_boolean.tv_x: hidden: true input_boolean.mac_x: hidden: true input_boolean.candles_x: hidden: true input_boolean.game_x: hidden: true 
add some scripts.
script: tv: alias: "TV" sequence: service: input_boolean.toggle entity_id: input_boolean.tv_x game: alias: "Game" sequence: service: input_boolean.toggle entity_id: input_boolean.game_x mac: alias: "Mac" sequence: service: input_boolean.toggle entity_id: input_boolean.mac_x candles: alias: "Candles" sequence: service: input_boolean.toggle entity_id: input_boolean.candles_x 
so instead of key'ing off the input_booleans, i key off the script call. "alexa, turn on candles" calls the script, which toggles the i_b but i only care about the state change of the script. then NR does it's thing.
https://imgur.com/Hky9fWd
notice tho, that it's a little smart. if the tv is already on, via that global.var, then it just switches inputs, otherwise it turns it on, waits 7 seconds, then switches inputs.
okay, here's something REALLY advanced.
i have a second pi running cgminer with a USB hub and some USB stick ASIC bitcoin miners. and every once and a while, they stop working and need to be reset. and you can't just restart, you gotta kill the power to the hubs to get them to reset. and then restart cgminer.
enter NR cgminer node and the cgminer API.
https://imgur.com/POSkjrp
so every 5 mins, hit the cgminer API, it returns stats in json, dump those to mqtt. use the function node to pull out the array nested values we need to look at. look for a zero value in any of them. if the input_boolean "auto-reset-miner" is on, then lets reset.
stop cgminer, wait, turn off the USB hub, wait, turn on hub, wait, start cgminer, send an alert to mqtt and SMS me.
now the real magic is the red exec "start cgminer" node. because we stopped cgminer, we have to start it again, on a whole other computer than NR is on.
it basically does a SSH into the miner pi and starts up cgminer. this was difficult to accomplish inside a docker of NR. i had to move some ssh keys around and then reference them with full paths. then i had to do an ssh-copy-id so it didn't require a password.
ssh -i /data/.ssh/id_rsa [email protected] "start cgminer commands" 
anyways, i'm really proud of this one. it was difficult to figure out how to make it work. lots of different moving parts coming together.
here's something i'm still working on. a remote control using the NR dashboard UI.
https://imgur.com/nkRpAsf
something i can just put an icon on my iphone home screen and use from the couch.
https://imgur.com/maeJm0Q
anyways, enjoy.
or don't. i'm not your cruise director.
you do you.

How do I mine Dogecoin?

How do I mine Dogecoin?
Let’s take a lucky guess that you’re here today because you’ve heard a lot about cryptocurrencies and you want to get involved, right? If you’re a community person, Dogecoin mining might be the perfect start for you!
Bitcoin was the first in 2009, and now there are hundreds of cryptocurrencies. These new coins (that operate on their own native blockchain) are called altcoins or alternative coins. One popular altcoin is Dogecoin. It can be bought, sold and traded, just like Bitcoin. It can also be mined!
So, what is Dogecoin mining?
You’ll know what hardware and what software you need to get started. You’ll also know whether or not Dogecoin mining is for you!
So, where would you like to start? The beginning? Great choice. Let’s have a quick look at how Dogecoin got started.
A (Very) Short History of Dogecoin
In 2013, an Australian named Jackson Palmer and an American named Billy Markus became friends. They became friends because they both liked cryptocurrencies. However, they also thought the whole thing was getting too serious so they decided to create their own.
Palmer and Markus wanted their coin to be more fun and more friendly than other crypto coins. They wanted people who wouldn’t normally care about crypto to get involved.
They decided to use a popular meme as their mascot — a Shiba Inu dog.

https://preview.redd.it/rymnyyz1iil31.png?width=303&format=png&auto=webp&s=f138e3fe56eef9c6b0e7f49b84fefc41fb83e5aa
Dogecoin was launched on December 6th, 2013. Since then it has become popular because it’s playful and good-natured. Just like its mascot!
Dogecoin has become well-known for its use in charitable acts and online tipping. In 2014, $50,000 worth of Dogecoin was donated to the Jamaican Bobsled Team so they could go to the Olympics. Dogecoin has also been used to build wells in Kenya. Isn’t that awesome!
Users of social platforms – like Reddit – can use Dogecoin to tip or reward each other for posting good content.
Dogecoin has the 27th largest market cap of any cryptocurrency.
Note: A market cap (or market capitalization) is the total value of all coins on the market.
So, Dogecoin is a popular altcoin, known for being fun, friendly and kind. It’s a coin with a dog on it! You love it already, don’t you?
Next, I want to talk about how mining works…
What is Mining?
To understand mining, you first need to understand how cryptocurrencies work. Cryptocurrencies are peer-to-peer digital currencies. This means that they allow money to be transferred from one person to another without using a bank.
Every cryptocurrency transaction is recorded on a huge digital database called a blockchain. The database is stored across thousands of computers called nodes. Nodes put together groups of new transactions and add them to the blockchain. These groups are called blocks.
Each block of transactions has to be checked by all the nodes on the network before being added to the blockchain. If nodes didn’t check transactions, people could pretend that they have more money than they really do (I know I would!).
Confirming transactions (mining) requires a lot of computer power and electricity so it’s quite expensive.
Blockchains don’t have paid employees like banks, so they offer a reward to users who confirm transactions. The reward for confirming new transactions is new cryptocurrency. The process of being rewarded with new currency for confirming transactions is what we call “mining”!

https://preview.redd.it/rcut2jx3iil31.png?width=598&format=png&auto=webp&s=8d78d41c764f4fe4e6386da4f40a66556a873b87
It is called mining because it’s a bit like digging for gold or diamonds. Instead of digging with a shovel for gold, you’re digging with your computer for crypto coins!
Each cryptocurrency has its own blockchain. Different ways of mining new currency are used by different coins where different rewards are offered.
So, how do you mine Dogecoin? What’s special about Dogecoin mining? Let’s see…
What is Dogecoin Mining?
Dogecoin mining is the process of being rewarded with new Dogecoin for checking transactions on the Dogecoin blockchain. Simple, right? Well no, it’s not quite that simple, nothing ever is!
Mining Dogecoin is like a lottery. To play the lottery you have to do some work. Well, actually your computer (or node) has to do some work! This work involves the confirming and checking of transactions which I talked about in the last section.
Lots of computers work on the same block of transactions at the same time but the only one can win the reward of new coins. The one that earns the new coins is the node that adds the new block of transactions to the old block of transactions. This is completed using complex mathematical equations.
The node that solves the mathematical problem first wins! It can then attach the newly confirmed block of transactions to the rest of the blockchain.
Most cryptocurrency mining happens this way. However, Dogecoin mining differs from other coins in several important areas. These areas are;
  • Algorithm: Each cryptocurrency has a set of rules for mining new currency. These rules are called a mining or hashing algorithm.
  • Block Time: This is the average length of time it takes for a new block of transactions to be checked and added to the blockchain.
  • Difficulty: This is a number that represents how hard it is to mine each new block of currency. You can use the difficulty number to work out how likely you are to win the mining lottery. Mining difficulty can go up or down depending on how many miners there are. The difficulty is also adjusted by the coin’s protocol to make sure that the block time stays the same.
  • Reward: This is the amount of new currency that is awarded to the miner of each new block.
Now, let’s compare how DogeCoin mining works compared to Litecoin and Bitcoin…
Mining Comparison
Bitcoin uses SHA-256 to guide the mining of new currency and the other two use Scrypt. This is an important difference because Scrypt mining needs a lot less power and is a lot quicker than SHA-256. This makes mining easier for miners with less powerful computers. Fans of Litecoin and Dogecoin think that they are fairer than Bitcoin because more people can mine them.
Note: In 2014, Litecoin and Dogecoin merged mining. This means they made it possible to mine both coins in the same process. Dogecoin mining is now linked with Litecoin mining. It’s like two different football teams playing home games in the same stadium!
Mining Dogecoin is a lot faster than mining Litecoin or Bitcoin. The block reward is much higher too!
Don’t get too excited though (sorry!). Dogecoin is still worth a lot less than Bitcoin and Litecoin. A reward of ten thousand Dogecoin is worth less than thirty US Dollars. A reward of 12.5 Bitcoin is currently worth 86,391.63 US Dollars!
However, it’s not as bad as it sounds. Dogecoin mining difficulty is more than one million times less than Bitcoin mining difficulty. This means you are much more likely to win the block reward when you mine Dogecoin.
Now I’ve told you about what Dogecoin mining is and how it works, would you like to give it a try?
Let’s see what you need to do to become a Dogecoin miner…
How to Mine Dogecoin
There are two ways to mine Dogecoin, solo (by yourself) or in a Dogecoin mining pool.
Note: A Dogecoin pool is a group of users who share their computing power to increase the odds of winning the race to confirm transactions. When one of the nodes in a pool confirms a transaction, it divides the reward between the users of the pool equally.
Dogecoin Mining: Solo vs Pool
When you mine as a part of a Dogecoin pool, you have to pay fees. Also, when the pool mines a block you will only receive a small portion of the total reward. However, pools mine blocks much more often than solo miners. So, your chance of earning a reward (even though it is shared) is increased. This can provide you with a steady new supply of Dogecoin.
If you choose to mine solo then you risk waiting a long time to confirm a transaction because there is a lot of competition. It could be weeks or even months before you mine your first block! However, when you do win, the whole reward will be yours. You won’t have to share it or pay any fees.
As a beginner, I would recommend joining a Dogecoin pool. This way you won’t have to wait as long to mine your first block of new currency. You’ll also feel like you’re part of the community and that’s what Dogecoin is all about!
What You Need To Start Mining Dogecoin
Before you start Dogecoin mining, you’ll need a few basics. They are;
  • A PC with either Windows, OS X or Linux operating system.
  • An internet connection
  • A Shiba Inu puppy (just kidding!)
You’ll also need somewhere to keep the Dogecoin you mine. Go to Dogecoin’s homepage and download a wallet.
Note: A wallet is like an email account. It has a public address for sending/receiving Dogecoin and a private key to access them. Your private keys are like your email’s password. Private keys are very important and need to be kept completely secure.
There are two different types; a light wallet and a full wallet. To mine Dogecoin, you’ll need the full wallet. It’s called Dogecoin Core.
Now that you’ve got a wallet, you need some software and hardware.
Dogecoin Mining Hardware
You can mine Dogecoin with;
  • Your PC’s CPU: The CPU in your PC is probably powerful enough to mine Dogecoin. However, it is not recommended. Mining can cause less powerful computers to overheat which causes damage.
  • A GPU: GPUs (or graphics cards) are used to improve computer graphics but they can also be used to mine Dogecoin. There are plenty of GPUs to choose from but here are a few to get you started;SAPPHIRE Pulse Radeon RX 580 ($426.98)Nvidia GeForce GTX ($579.99)ASUS RX Vega 64 ($944.90)
  • A Scrypt ASIC Miner: This is a piece of hardware designed to do one job only. Scrypt ASIC miners are programmed to mine scrypt based currencies like Litecoin and Dogecoin. ASIC miners are very powerful. They are also very expensive, very loud and can get very hot! Here’s a few for you to check out;Innosilicon A2 Terminator ($760)Bitmain Antminer L3 ($1,649)BW L21 Scrypt Miner ($7,700)
Dogecoin Mining Software
Whether you’re mining with an ASIC, a GPU or a CPU, you’ll need some software to go with it. You should try to use the software that works best with the hardware you’re using. Here’s a short list of the best free software for each choice of mining hardware;
  • CPU: If you just want to give mining a quick try, using your computer’s CPU will work fine. The only software I would recommend for mining using a CPU only is CPU miner which you can download for free here.
  • GPU: If you mine with a GPU there are more software options. Here are a few to check out;CudaMiner– Works best with Nvidia products.CGminer– Works with most GPU hardware.EasyMiner– User-friendly, so it’s good for beginners.
  • Scrypt ASIC miner:MultiMiner– Great for mining scrypt based currencies like Litecoin and Dogecoin. It can also be used to mine SHA-256 currencies like Bitcoin.CGminer and EasyMiner can also be used with ASIC miners.
Recommendations
You’re a beginner, so keep it simple! When you first start mining Dogecoin I would recommend using a GPU like the Radeon RX 580 with EasyMiner software. Then I would recommend joining a Dogecoin mining pool. The best pools to join are multi-currency pools like Multipool or AikaPool.
If you want to mine Dogecoin but don’t want to invest in all the tech, there is one other option…
Dogecoin Cloud Mining
Cloud mining is mining without mining! Put simply, you rent computer power from a huge data center for a monthly or yearly fee. The Dogecoin is mined at the center and then your share is sent to you.
All you need to cloud mine Dogecoin is a Dogecoin wallet. Then choose a cloud mining pool to join. Eobot, Nice Hash and Genesis Mining all offer Scrypt-based cloud mining for a monthly fee.
There are pros and cons to Dogecoin cloud mining;
The Pros
  • It’s cheaper than setting up your own mining operation. There’s also no hot, noisy hardware lying around the house!
  • As a beginner, there isn’t a lot of technical stuff to think about.
  • You get a steady supply of new currency every month.
The Cons
  • Cloud mining pools don’t share much information about themselves and how they work. It can be hard to work out if a cloud mining contract is a good value for money.
  • You are only renting computer power. If the price of Dogecoin goes down, you will still have to pay the same amount for something that is worthless.
  • Dogecoin pools have fixed contracts. The world of crypto can change very quickly. You could be stuck with an unprofitable contract for two years!
  • It’s no fun letting someone else do the mining for you!
Now you know about all the different ways to mine Dogecoin we can ask the big question, can you make tons of money mining Dogecoin?
So, Is Dogecoin Mining Profitable?
The short answer is, not really. Dogecoin mining is not going to make you a crypto billionaire overnight. One Dogecoin is worth 0.002777 US Dollars. If you choose to mine Dogecoin solo, it will be difficult to make a profit. You will probably spend more money on electricity and hardware than you will make from Dogecoin mining. Even if you choose a Dogecoin pool or a cloud pool your profits will be small.
However, if you think I am telling you to not mine Dogecoin, then you’re WRONG! Of course, I think you should mine Dogecoin!
But why? Seriously…
Well, you should mine Dogecoin because it’s fun and you want to be a part of the Dogecoin family. Cryptocurrency is going to change the world and you want to be part of that change, right? Mining Dogecoin is a great way to get involved.
Dogecoin is the coin that puts a smile on people’s faces. By mining Dogecoin you’ll be supporting all the good work its community does. You’ll learn about mining from the friendliest gang in crypto. And who knows? In a few years, the Dogecoin you mine now could be worth thousands or even millions! In 2010, Bitcoin was worthless. Think about that!
Only you can choose whether to mine Dogecoin or not. You now know everything you need to know to make your choice. The future is here. So, what are you going to do?

Need 2nd Pool Again

Pool Source Code: https://github.com/biblepay/BiblePayPool
Deploying a BiblePay Pool: https://github.com/biblepay/BiblePayPool/blob/masteDeploying%20A%20BiblePayPool.docx
Requirements: "Win 2012 r2 server, 4 processors, static IP, IIS 7, SQL Server 2016, 8 gig ram, 100 gig drive, anti-ddos enabled. The vultr option is about $60 a month." -Rob
"There can be no automatic installation for a pool, There are no shortcuts to running a pool. You have to be a master SQL administrator, DBA, weak programmer, security admin and windows engineer to run a pool. You have to for one compile the source in visual studio 2017, and be ready for redeploying it when it changes. You have to spend 20 hours a week answering emails and doing adhoc sql queries, etc. If we had someone that even believed they could just compile it once and let it run it will be down within one month and all your coins will be lost."

"By the way, a couple of days ago, I started to look into the possibility of using another, existing pool software with biblepay, like NOMP or MPOS. I'm currently collecting all required information to write a bridge between MPOS and Biblepay, and it will most likely take another 1-2 weeks before a first usable result will be visible, but I'm optimistic that it can be done.
The problem of using an existing pool software is that Biblepay is not using the stratum mining protocol, the standard for most current pools. Plus maybe the custom Proof Of Biblehash, I'm currently looking into the codes to understand if that is something that MPOS needs to learn." -Lichtsucher
I hope that a second pool (with a different software) will help to solve some of the current problems, but it will take some time.
"The biggest problem is it not using standard pice of code from bitcoin-core. So we can't copy&paste mining code to another library and use it with exisitng minig software.
I develop MPOS few years ago, and there is not problem with stratum protocol, couse stratum is only between miner and pool. We need to develop standalone miner (without biblepayd) and make library to use it with eg. https://github.com/zone117x/node-open-mining-portal stratum pool can be connected with MPOS database and send there shares. MPOS is only for calculate shares diff and block payout, and send payout to users.
I have somewhere contact to main developer of https://github.com/zone117x/node-open-mining-portal (yeah I'am on credits Wink ). I will try ask him how hard is to implement biblepay kjv algorithm, but I think we need make some donation for this. But still it will be 50% of all we need." -svirusxxx2
Quote from: svirusxxx2 on Today at 06:33:19 AM We need to develop standalone miner (without biblepayd) and make library to use it with eg. https://github.com/zone117x/node-open-mining-portal
Quote from: Lichtsucher on Today at 06:57:24 AM As I understood the Proof Of Biblehash and the upcoming POL algorithm, a full client as biblepayd is required. The client might be smaller, but will it change a lot? Plus, with the current rate of changes in the core code, maintaining a second miner seems a lot of hard work. I don't know how exactly PoL works, I must see some documentation (any one have some link ? )
I make little mistake... We can add some code to biblepayd to have stratum support, and standalone miner is not required. Or we also can write some proxy between biblepay and exisiting protocol, and stratum/longpooling. But still is some work to do with C++ (where my skills is very weak).
We exactly need three things 1/ write new option to biblepayd for reciving job and sending shares to node-open-mining-portal 2/ add library to this project: https://github.com/zone117x/node-multi-hashing 3/ add support to eg. https://github.com/zone117x/node-open-mining-portal
position 3 I can write, but 1,2 it's too hard for now C++ developer" -svirusxxx2
"To everyone talking about NOMP, if NOMP was possible I would have written the original pool in NOMP.
There are massive things missing. One there is no hash function in python that is going to get you the biblehash.
Two, there is no software (like cgminer or sgminer) that is going to interact with NOMP.
If you think I did that bad of a job with the pool, I think you should find another community.
Ill fix the pool software if its not working properly, as it has historically worked with over 98% uptime and I kept it maintained, and after 1/2 day of being behind you are talking about porting it to NOMP. Shameful.
Anyway, do whatever you want, its not going to work and Im not going to help code pieces of the core client to work with it, as the pool does a lot more than you think it does. It is also a hub for adding orphan features." -Rob

A few thoughts - Wednesday, July 23, 2014

Good evening! A few thoughts for dinner tonight:

Life is about economics

Many people don't place enough emphasis on economics when making decisions about their lives, instead making incorrect decisions based entirely upon emotions. Economics, which is the study of how scarce resources are allocated, affects anything of value that often seems to have little to do with what most people consider to be money.
There are some people who repeat trite sayings like "life isn't all about money." In fact, life is all about money, as anyone who doesn't have any can attest. You don't have to spend your money on cars or houses to participate in economics. You can also trade money for other things like years of life, time off, avoiding prison, and so on. One of the more interesting economic theories links abortion, money, and crime, on the theory that people with little money don't spend enough time with their kids to instill positive values in them, and therefore allowing abortions in 1973 resulted in a reduction in crime in the 90s when those kids never grew up.
On Monday, I talked about the idea that some people will ignore the regulations in New York because they are willing to take the risk of prison in exchange for money. Shortsighted people may look at such a trade and reply that any amount of money isn't worth a year in jail, but the best way to look at this is to take something you want, or don't want to do but need to, and replace it directly instead of using money as an intermediary. This is called the transitive property in mathematics: it states that if "A=B and B=C," then "A=c." Now replace the variables. If you could guarantee that one year in jail earned you one million dollars, and one million dollars was enough money to avoid working for 25 years, then one year of jail is worth 25 years of non-work. When you take out the money from the equation, you get the same result but it is easier to see how economics causes people to do what they do.
Consider some other examples. Someone who spends 1/4 of his or her time partying in college (1 year) gets lower grades and can't get a job for 6 months after graduation, whereas not partying at all results in getting a job the day after graduation. If the new engineer makes $50,000/yr, that means that the partier makes $25,000 less over the course of his lifetime. But that's not all, because that $25,000 will compound in interest over time (on average, the stock market will double every 12 years). Therefore, if someone graduating today can expect to work until age 80 (or 60 years), then that $25,000 put into stocks will be worth $800,000 at retirement. If one year of a comfortable lifestyle costs about $50,000, then we can take the money out of the equation and conclude that partying for one year in college has a price of 20 years of retirement.
Finally, let's consider the example of terrorism. Those airport X-ray scanners cost $90m and the risk of death due to terrorism is about 20m:1. It costs about the same amount to research a new cancer drug. The risk of dying of cancer is about 5:1. Therefore, if the drug is effective in 1 in 4m people, then it would have been a better investment than the X-ray scanners. Most drug studies express the results in terms of how many of the treated patients got better compared to the control patients who were untreated. In percentage terms, the effectiveness of the drug would have to be 0.000025% for it to be a better deal. These odds assume that if the machines were removed, then the risk of a terrorist attack would at least double, which is doubtful. In fact, if every person who ever developed cancer in the past 80 years were treated with this drug, only 375 of those billions would have to be cured for it to make sense to ditch the airport screeners.
The conclusion here is that if you want to make the best decisions for your life, you need to recognize that everything, even life and death, can be reduced to money. In a perfect world, there would be some things that are priceless, but this is a world where things are scarce and people suffer and die all the time. Money isn't just a concept that determines how much stuff you can buy; it places value on things like time, health, and freedom that can, like other goods, be risked and traded for other things of value.

Transaction volume not rising quickly enough

Some have tried to argue that the low transaction volume recently is fine because it is not falling. I disagree because in technology, you are either innovating or you are dying. Software is either in development, or it is abandoned and nobody wants to use it. In business, your company is either growing or it has headed towards a decline. There are no steady states in these industries.
In order for bitcoins to succeed, the transaction volume not only needs to be growing, but it needs to be growing very quickly. If you draw a line through the transaction volume chart and look at its slope, you can extrapolate growth to approach the same level as MasterCard around... when? 2100? Obviously, the world will be a different place then and something else will have grown faster than bitcoin by that point (or people will have just given up on the technology).
While past growth might seem like it is unprecedented, it is exactly what we would expect to see for a new technology that would achieve mass adoption in 5 or 10 years. If that growth slows down to, say, 1/3 of its previous level, then mass adoption would be expected to take as long as 30 years, which is unreasonable. With the world changing at an accelerated pace, a 30-year adoption cycle is not realistic anymore for any technology regardless of area of life.
If bitcoins are to succeed, the growth needs to continue at a rate similar to the past. While many traders would be happy with 50% returns per year, that sort of growth simply can't support the technology. When I suggest that the transaction volume is a danger sign, the volume doesn't have to go down in order to be a problem. It simply has to stop increasing at the rate necessary for bitcoin to break out and become the dominant force in the economy.

Configuration is much harder than development

Over the past few days, I've been struck by something that I knew all along, but was not aware of how important it is to recognize. In developing an engineering system, configuring other people's software is far more difficult than writing your own is. In fact, if what the other software is doing is simple enough, I'm now convinced that it makes more sense to completely rewrite it, because you'll gain a better understanding of the problem and probably come out with a better-written solution.
Right now, our pool has complete software that has no known bugs. We want to release it for testing so that additional bugs can be found and fixed. One would think that if someone gave you the code for a complete system and told you to set it up and start making money, you could do that in a few days. Consider what seems like a simple problem: setting up a router. You pay $200 to a company like Cisco only to find out that their router freezes when it has more than 30 port forwarding rules applied. They list this as a "known issue" that can only be solved with a reboot at the remote location, a procedure that takes hours. Surely the biggest networking company in the world can afford to release a firmware update that allocates a few kilobytes of memory to host more port forwarding rules.
Other examples of this problem are Cryptsy's API, where their customer service released a bug that broke the entire system for 12 hours, "pusher," a service that receives data from remote sites but does not reconnect upon disconnection as it promises to, CGMiner, which requires that bandwidth-wasting duplicate data be sent to the client every 30 seconds or else it disconnects with an error message stating that the connection was interrupted, EFI, which is a million-line operating system that runs underneath Windows and Linux and which is a patchwork of thrown-together code from so-called "professional" companies, and the bitcoin daemon, which until recently simply didn't compile under Debian.
Finally, many people fail to recognize how important documentation is to software. Without documentation, nobody else can use the software, period. In the case of APIs and developer-centric software, a function that is undocumented is as good as useless. There are some javadocs out there that have functions like "sendmoney" with the default description. How do you even begin to know what that does, and would you trust calling such a function blind?
So many products have so many issues that a good rule of thumb is that if you can rewrite whatever the other software is doing in one weekend or less, then it is probably worth the effort to just rewrite it. Code quality is a serious issue in the bitcoin community. In addition to criticizing the lack of development of the core software, we should also be drawing attention to the issue of how much of the surrounding code is often unusable.

Just getting started, have a miner up and running...

Hey, Everyone.
This is a long post introducing myself and what I am up to. If you want to skip over my story, I have a question below about Litecoin pools.
My brother contacted me to talk because I'm an IT Pro, and he asked if I had looked into BTC mining. I told him I had heard of bitcoins, but didn't really ever look into it. Well... this weekend I took a trip down the rabbit hole and here I am with my first miner doing about 660Khash/s with a couple other CPU miners trickling on as well.
I've spent many hours learning about this from reading, trying miners, learning about the coming ASIC and how bitcoin and litecoin differ (sha-256 vs scrypt), so I feel like I'm starting to get my head around all of this. It became immediately obvious that mining BTC with a couple 7850's was a complete waste of time and effort. When I heard about litecoins, and realized they are still very new, I thought, what the hell, let's do it. I have a bunch of hardware laying around, so I might as well try it.
I don't know if I will ever make any money off of this, but I can tell you that I have had a friggin' blast Frankensteining a miner rig together. My miner is a 1st gen Core i7 (920) sitting on an ASUS P6T Delux mobo, and I went out and grabbed what I could at Best Buy for AMD cards, which are a couple XFX R7850 OC Edition units. They are garbage with awful cooling, but they were cheap, and local.
I'm running Ubuntu server 12.10 with Openbox and Roxterm for the interface. I got the idea from looking over some instructions for setting up a headless hashing machine over at hashcat.net. It's currently running cgminer, but I'm going to put a CPU miner on it today, since the i7 is idling at 0-.1% usage while mining on the GPUs.
The fun? Well, I'm a geek and this all reminds me of the mid 1990's when me and my gaming friends were buying Celeron chips and overclocking them for gaming, and putting the very first (VooDoo) 3D cards in our machines. Back then if you were tweaking on your hardware, shit was crashing all the time. Building a gaming rig now is easy, unless you are case modding and doing extreme overclocking.
I've made this Ubuntu server crash a few times, and overheated the video cards to shut down while I was tweaking all the settings.. I love that shit. Means I'm pushing it to the max for what I have available, just like the OG gaming days.
Can anyone point me toward a good, stable litecoin pool? I originally set up with Coinotron, but they have been down more than up over the last few days. I set up an account with Pool-X.eu, but their website is so slow I can't tolerate it. Right now I'm using Burnside's but I'm getting a lot of stales there (30%).
Is everyone having the same issues since litecoins aren't really mainstream yet, or am I just signing up with the wrong pools?
Looking forward to chatting with all of you, and thanks in advance for any advice you can offer.

$2500 if paid with Bitcoin. I'd most preferably take Bitcoin, as that'd result in me giving you the best price possible since theres NO FEES. Don't buy it through eBay, they charge out the rear in fees. If you want to go that route, let's do PayPal. Send me a message!

7 GPU mining rig in a custom aluminum structure that I built. Pushes as much as 3.4MH/s but I'll ship it at about 3+MH/s to give you something reliable to start on.
I URGE you to read my Reddit threads and dig into the comments for a great deal of information about this rig. You may see me mentioning a Semphron 145 processor- that thing was terrible and made the rig unstable so I upgraded it to a AMD FX-6300 6-core 3.5GHz processor and the now rig screams. Massive difference with a high-end processor. Runs games on ultra/max settings, obviously ;)

I want to throw in a newbish disclaimer. I must impress upon you the fact that this is a mining rig running Linux. If you're not good with computers then mining might not be for you. I don't care if you've upgraded your own RAM or hard drive one time, that means nothing. You need to be proficient with computers to own a mining rig running Linux. Most of the dirty work is done with this rig. It's been running SMOOTH for months now.
I'll ship it to where you can plug it in and it will automatically turn on and start mining in Linux. It will also have Windows installed, but you'll have to do a little legwork getting the drivers installed to run all 7 video cards- I wasn't interested in Windows mining so I didn't bother getting the 7th going- I got 6 video cards mining in Windows. The drivers have come out to make all 7 work but like I said- Linux mining works fine for me.
As with any rig, we're pushing these cards to the limit. You'll have to check on the rig periodically to make sure cgminer is not reporting any SICK/DEAD cards. That's normal, as with any mining rig the cards can hang or overheat and protect themselves by shutting off. You'd still be mining on all the other cards, only that one card drops offline. All mining rigs do this when you're pushing max hashrate.
I like to use the Belkin WeMo to remotely monitor my wattage, if it drops below a threshold I know I've got a dropped card and I can reset the rig remotely, it automatically boots back up and starts mining again. There's other options like CGwatcher that are pretty slick, but I've found what works for me and I'll stick to it.
It can be run fairly quiet. I ran it with no external cooling fans for a while successfully at about 3.2MH/s. I since threw some fans back on it since I don't like keeping the AC on all day and its warming up outside. Fans are included.
I offer support. I want to see my creation keep digging for a long time, that said I'll support you in getting it started back up in its new home. Check my Reddit threads for references, I know damned well what I'm talking about and I'll see to it that you get up and running.
I'm not accepting returns on this rig. Its sold as-is. Because these are sensitive electronic components, I can't be responsible for your damaging it. Its a tough well built rig, I assure you. It will work 100% when I shut it down, it should work 100% when you receive it.
Before buying or bidding I HIGHLY SUGGEST you drop me a message so we can sort out the details and make sure that this is the right rig for you!
