21  Other / Beginners & Help / Effective Antivirus on: June 16, 2011, 08:49:41 AM
I currently use Avira, and so far it's worked pretty well. Any criticisms? Obviously I like it for it's price as well, and I barely web browse on the PC I use it on, but I am almost constantly connected online, so any recommendations would be appreciated.
22  Other / Beginners & Help / Anyone use KeePass? on: June 16, 2011, 08:35:40 AM
Anyone? How effective/secure is it? I've been looking for a safe way to manage my passwords that I could take with me and access just about anywhere. Thought about a plaintext file (encrypted obviously), but management of all passwords becomes cumbersome. I also needed something multiplatform, so this seems like a good choice, but, just curious for input or other suggestions.

They are nothing like Paypal. Paypal is a evil company. I have yet to hear of any issues with Dwolla.

What makes Paypal so evil? I'm just curious where all this hate is coming from since I've never had problems and haven't heard much about the problems that happen.

Have you looked into GPU mining? Much more efficient. And Pooled GPU mining a further step up.
27  Bitcoin / Development & Technical Discussion / Portable Truecrypt Install on: June 14, 2011, 07:01:10 PM
Not sure if this is the right forum, so bear with me. Basically what I want to do is create an encrypted container on a USB drive that I can store files in (including a wallet file) and take with me. I'd like to be able to access it from any computer, but chances are not everyone's going to have truecrypt installed. Does anyone know of a way to install and run truecrypt from a thumb drive? I've looked around online, but I'd like to have an install that can run on any (or the most popular at least) OS's. I'm assuming this would require multiple installs, but if anyone could help or point me in the right direction I'd appreciate it. Thank you.

Anyone have personal experiences with either? Both? Just wondering what the pros and cons of each are? Also, anything to read up on specifics on using it? I've never used it, nor Dwolla. Thanks

What would be the best solution for the lack of encryption problem? The only thing I can think of would be to created an encrypted volume (via truecrypt) and drop  the wallet file in there. But then it'd have to be replaced any time you were mining. I'm not talking about a back up here, I mean the original obviously.

Dropping a wallet into an encrypted disk does not protect at all. The wallet must be created in there and never be stored outside.

I thought so, just wondering if there was some solution I hadn't thought of.

Any idea how it happened and how others can prevent it from happening to them?

I'm pretty safe with my PC, but if this somehow happened because you were opened up to a pool or something, I'd like to know and take preventative measures.
32  Bitcoin / Pools / Re: BTC Guild - 0% Fees, Long polling, SSL, JSON API, and more [~1500 gH/sec] on: June 13, 2011, 06:34:37 PM
You can configure your miner to mine at a backup pool especially if you use poclbm.exe.
Run two instances of poclbm per GPU. Use the "f" command to give one pool priority over another. The lower the "f" value, the higher the priority.
-f30 to one pool will have priority over -f60 on a second pool.
This will split your GPU processing power to about 92% | 8% between the two pools. If one pool is idle, poclbm will automatically shift your mining power to the backup. This is even easier to setup and monitor using guiminer.
This has worked flawlessly for me and has always kept my GPUs at 100% through BTC Guild's growing pains.
How exactly do you do this? I've been trying to figure it out with no luck so far.

If you are using command line poclbm.exe (and an ATI/AMD based video card) try this:

Code:
poclbm.exe --user=username_workername --pass=password -o btcguild.com -p 8332 -d0 --verbose -v -w128 -f30

And then run poclbm.exe again with you other pool worker sign-on info.

Code:
poclbm.exe --user=username --pass=password -o other.pool.address -p 8332 -d0 --verbose -v -w128 -f60


If you are using GUIminer (adn ATI/AMD video cards) do this:
  • Go to "File" menu and choose "New OpenCL miner"
  • A pop-up windows will appear to name the miner. You can name it what even you want. I named it "Guild."
  • This will create a new tab in the GUIminer window. Click on it so we can start configuring.
  • In the "Server dropdown box, choose "BTC Guild."
  • In the Username box, type in your username_workername. Fill in your password in the password box.
  • In the Device name, choose your GPU. If you have multiple GPUs, they will be listed in there. They are numbered starting with 0. You will also see your CPU as a usable device. (This is a hint that you can use your CPU to mine, but it will slow your system to a crawl.)
  • In the "Extra Flags" box you can type in:
Code:
-v -w128 -f30
  • You can tweak these numbers to try to get as many Mhash/sec as you can.
  • Remember to go back to the "File" menu and "Save Settings"

Now, repeat these steps again. This time using a different pool. When you get to "Device" just use the same device again.
In the "extra flags" box, just use -f60  or any higher number.



The main point is to use two miner per GPU. If you have 2 video cards, setup 4 miners.

Again, thank you for the help, it will be rewarded. Is there anywhere I can find what these flags mean exactly? I mean, I can put all this in, but I'd like to know what the -v -w and -f are for. Also, I assume the higher number -f takes precedent correct? So I'd set the btc guild hire, but if I wanted to fall back to solo mining it'd be set lower?

Quicker?  
eleuthria, you are doing a fantastic job. We know this is not your primary job and are working on the pool every chance you get.
We, the mining public, can be patient while you work on setting up your fifth server in less than a month.

To all BTC Guild miners:
You will experience some problems when the new server is put online. There is no way to avoid it. All the servers must be in sync and there is no way to do that without some service interruptions.

While BTC Guild is growing, consider setting up a "back-up" pool.

You can configure your miner to mine at a backup pool especially if you use poclbm.exe.
Run two instances of poclbm per GPU. Use the "f" command to give one pool priority over another. The lower the "f" value, the higher the priority.
-f30 to one pool will have priority over -f60 on a second pool.
This will split your GPU processing power to about 92% | 8% between the two pools. If one pool is idle, poclbm will automatically shift your mining power to the backup. This is even easier to setup and monitor using guiminer.
This has worked flawlessly for me and has always kept my GPUs at 100% through BTC Guild's growing pains.

How exactly do you do this? I've been trying to figure it out with no luck so far.

First off, what exactly is the "stale" count? What is an average stale count for a round or per some period of time? How do I prevent them? Thank you for the help

This post will help people new to Bitcoins get up to speed. Everyone else can skip it (or read it for a refresher).

Bitcoins are created by "solving a block." A "Block" is just a collection of Bitcoin transactions that have been hashed and added to the official chain of Bitcoin blocks. The "confirmations" the you get when you send or receive a transaction is the result of your transaction being hashed and included in the block chain.
Since solving a block is so difficult, you get a reward for doing so... 50 Bitcoins.

How do I solve a block?
To complete a new block your computer running mining software tries to guess the hash of the new block based off the hash of the old block. You aren't really computing the answer to an equation per say. You are just making a guess.
In fact, it helps to look at this like buying lottery tickets. The chances of winning the lottery are low, but  you can increase you odds if you buy more tickets.
Your miners compute hashes against the current block and when it thinks it has a potential winner, it submits it as a share. Hashes are generally measured in number of Mhases/sec or Ghashes/sec. This would be millions of hashes per second or billions of hashes per second (respectively). For example an Average ATI 5770 video card can compute roughly 150 to 200 Mhash/sec dependly on how you configure it.
The share you submitted is sent across the entire peer-to-peer Bitcoin network. All peers must agree if a share is the winner.

It's a lottery.
The percent chance that a single hash will be the winner is currently: 0.0000000000000004104346 or about 410,000,000,000,000 to 1.
This changes about every two weeks and is expected to get even tougher.
Even though the odds are so high, there is a potential for two clients to submit a winning share at the same time. When this happens, the Bitcoin peer-to-peer network choses the definitive winner. The loser's block is then declared invalid. Invalid blocks are a rare occurrence, but it does happen.

Mining Pools
Since the probability of the average home computer to find the correct hash is so slim, people have started to "pool" their resources together--in much the same way an office might buy several lottery tickets together.
You along with all the others in the pool submit shares. When a block is solved among one of the pool members, the 50 Bitcoin reward is split among all those who submitted shares during that block. The more shares you submit, the larger your portion of the reward.
Pools are operated by groups, or individuals and are kept alive by taking a small cut of your profits (usually a fee of about 3%).

Bad Things - Stale Shares and Idles
When you belong to a pool, you are trying to solve a block that the pool has relayed to you:
  • The Pool gets the current block from the Peer-to-peer Bitcoin network.
  • It sends your miner that information.
  • Your miner works on it.
  • Your miner submits shares it thinks will be potential winners.
If a block is solved elsewhere on the Bitcoin network, the pool must tell you miner to stop what it is doing and start work on the new block.
If your miner does not get this new block information, it will continue to work on submitting shares for the previous block. When this happens, your shares are stale and do not count for anything.
If the pool does not send any block information to your miner, it will become idle and not do anything (not contributing).
The best way to fix any of these problems on the miner end is to stop--and restart the miner software. It will then submit a new request for new block information from the pool.

BTC Guild
To keep this on topic.....
The BTC Guild mining pool was created (founded?) by eleuthria. He has committed countless hours and many of his personal resources to bring the fastest growing Bitcoin mining pool in the world.
Of of this writing it is also the second largest pool in the world.
eleuthria has made numerous enhancements to the pool in the short months that it has been in existence. However, most of his time lately has been trying to keep up with the explosive growth of the pool. And when I say "explosive" I think one of his early servers has actually melted. (I may or may not be making up that last statement.)
The number one reason the pool is so popular is that this is the only pool that I know of where the fee is optional. You can choose how much or how little of a fee to pay.
That's right, you can join the pool for absolutely free if you want to. However, you get perks for paying a fee. And the more you pay, the more perks you get! 
Get all the perks for paying a fee of 2.5% or more. This is still a great value compared to other pools.
  • At 0% fee (the default) you can join the pool and get paid based on the number of shares you submit. When the pool solves a block, you get paid your portion after 120 confirmations.
  • At 2% you can setup Idle miner email warnings. If you miner(s) stop submitting shares for some reason, you can be notified by email.
  • At 2.5% you get the above. AND you get paid immediately when a block is solved. You don't have to wait for 120 confirmations. AND you get paid even if the block later becomes invalid.
It's the best pool I have seen. The community is great and the maintainer, eleuthria, is extremely active. You can reach him right on this discussion in the forum, or on IRC chat (#btcguild on FreeNode).

That was extremely helpful, thanks a lot. Most of it I understood, but could not figure out what the stale shares meant. Once I get some btc, I'll be sending you a small tip for your trouble.

36  Other / Beginners & Help / Guiminer prioritizing setup on: June 13, 2011, 05:31:26 AM
I've only been mining for about a day now, and first went solo just to see how it went. I knew in a day I'd almost assuredly get nothing, but, had to try. Anyways, I joined a pool (btcguild), and I use guiminer to mine. Seems to be working fine, but I was wondering how I could set it up so that if for some reason the server is dropped (on my end or theirs) I could have guiminer automatically start solomining? I've searched through the forums a bit, and any help is appreciated. Thank you in advance

So everytime someone loses their wallet everyone becomes a little richer...

But at the same rate, keeping the ratio consistent, meaning nothing. I believe. Not great with economics here.

I don't think so

You have Bob, Dick, Jane, Sue, and Dave


They each have 20% of the market

Dick gets drunk and drops his wallet into the sewar

Dick has 0% of the market, everyone else now has 25% of the market, now Sue hangs out with Dick and he punches her and steals her wallet, but loses it the same way... what an idiot... everyone now has 33% of the market, except for Dick and Sue...


I mean, obviously we're not working with whole percentages here... but same idea... and yea, the /entire/ market will increase in value, but that doesn't matter if you're selling your coins for cash... I don't think *scratches head*

Touche. Yeah, that should have been obvious.

I wouldn't really conclude that the massive post count here would be the distributed throughout the board had this rule not been put in place. The post rate is due to people increasing their quality standards to get into the meaningful sections of this forum.

Those were my thoughts. I've been posting more not because I want to voice my opinions on some of these more mundane topics (not all of them are so, but some are simply posted to be posted) but so I can get into more meaningful discussions with the people who have been here longer.
