How to mine Bitcoin with your CPU - JonathanMH

Bitcoin mining on OS X (10.7.5)

Posted this in /bitcoin first but was told that I might have better odds getting a good answer here instead.
I have a MBP from 2011 with the following stats:
I've been looking around for a miner to run on this computer while it idles, and I have noticed that there is no many alternatives out there for a Mac. In addition, I seem to be running into problems using the ones that do exist, most likely because most of them are GPU miners and the integrated graphics card on this machine is fairly shit.
I am aware that mining on this machine will never really give me much, but I enjoy the idea of having the computer at least try to do something useful. :)
Both DiabloMiner and Bitminter do not work for me.
The miner that at least seems to run is cgminer, however when checking the output it will show me an average hashrate of 0.0 Kh/s, and a certain number of "Work items generated locally".
Anyone have any suggestions to what I could do to be able to mine on this machine?

Dogecoin on Linux - The Complete Beginner's Guide

I'm writing this because I couldn't find a single condensed guide on compiling the wallet and running mining software on linux, specficially Ubuntu/Linux Mint. I combed Bitcoin and Litecoin forums for similar problems I was running into and eventually got everything nailed down, so here it is in one place, for new Shibes.
If you want to make a Dogecoin directory in your downloads folder to keep things organized, you will need to modify these commands to refelct the change. So instead of going to ~/Downloads/ you will need to go to ~/Downloads/Dogecoin and be sure to put the zipped files there when you download them, but the commands will be the same otherwise.
cwayne18 put in the work to make a PPA for the QT client here.
Ubunutu/Mint/Debian users should be able to install the client with the following commands:
sudo add-apt-repository ppa:cwayne18/doge sudo apt-get update && sudo apt-get install dogecoin-qt 
To update using this method, run
sudo apt-get update && sudo apt-get upgrade dogecoin-qt 
Compiling the Wallet Manually
I suggest using the PPA above, but if you want to compile manually, here you go.
1)Download the newest source from here. If you want to check out the Github page, click here
2)Unzip the package with the native client OR, navigate to your downloads and unzip
cd ~/Downloads unzip dogecoin-master.zip 
3)Now it's time to compile. You will need to install the dependencies, just copy and paste the following code. It will be a fairly large download and could take some time. It is always important to update before installing any new software, so we'll do that first and then install the dependencies.
sudo apt-get update sudo apt-get upgrade sudo apt-get install libssl-dev libdb-dev libdb++-dev libqrencode-dev qt4-qmake libqtgui4 libqt4-dev sudo apt-get install libminiupnpc-dev libminiupnpc8 libboost-all-dev build-essential git libboost1.53-all-dev 
4)Once that is done, go to the doge-coin master directory and compile:
cd ~/Downloads/dogecoin-maste sed -i 's/-mgw46-mt-sd-1_53//g' dogecoin-qt.pro qmake USE_UPNP=- USE_QRCODE=0 USE_IPV6=0 make -j3 
After running the qmake command you will likely see some text similar to
Project MESSAGE: Building without UPNP support Project MESSAGE: Building with UPNP supportRemoved plural forms as the target language has less forms. If this sounds wrong, possibly the target language is not set or recognized. 
It's perfectly normal, so don't worry about that.
Your Dogewallet is ready to go! The executable is in ~/Downloads/dogecoin-maste and called dogecoin-qt. Your wallet information is in ~/.dogecoin. You can run the wallet at any time by opening terminal and typing
cd ~/Downloads/dogecoin-maste ./dogecoin-qt 
Future upgrades to dogewallet are easy. Back up your wallet.dat, and simply follow the same directions above, but you'll be unzipping and building the newer version. You will likely need to rename the old dogecoin-master directory in ~/Downloads before unzipping the newest version and building. Also, it is likely that you will not need to install the dependencies again.
Alternate Method For Installing Dogecoin Wallet from Nicebreakfast
After installing the dependencies listed in step 3, open terminal, then navigate to where you want Dogecoin Wallet stored and run:
git clone https://github.com/dogecoin/dogecoin ./autogen.sh ./configure make 
then when the wallet is updated just run
git pull 
from the dogecoin directory.
GPU Mining
GPU mining requires CGminer. My suggestion is to get the executable already built. The creator of cgminer has removed the built file from his website, but I've uploaded it here
sudo apt-get install pkg-config opencl-dev libcurl4-openssl-dev autoconf libtool automake m4 ncurses-dev cd ~/Downloads tar -xvf cgminer-3.7.2-x86_64-built.tar.bz2 
Don't use anything newer than 3.7.2. The newer versions of CGMiner don't support GPU mining.
That's it! You have cgminer ready to go! You will run cgminer with the following syntax
cd ~/Downloads/cgminer-3.7.2-x86_64-built/ ./cgminer --scrypt -o stratum+tcp://SERVERNAME:PORT -u WORKER.ID -p PASS 
A good guide for fine tuning cgminer can be found here; follow the litecoin example.
EDIT
I had trouble getting cgminer running with a single line command, but running it via an executable .sh file works. This is covered in the cgminer setup guide I posted above but I'll put it here too. In the same directory that has the cgminer executable, you need to make a file called cgminer.sh and make it executable. It should contain the follwing:
export GPU_USE_SYNC_OBJECTS=1 export GPU_MAX_ALLOC_PERCENT=100 export DISPLAY=:0 find *.bin -delete sleep 5 ./cgminer 
Then you can call cgminer in terminal by doing ./cgminer.sh You will need a cgminer.conf file containing all your options. All of this is covered in the guide that is linked above.
A quick note about AMD drivers: They used to be a huge PITA to install and get working, but the newest Catalyst drivers are great. There's a GUI installer, everything works out of the box, and there is a lot of documentation. You can download them here: AMD Catalyst 14.6 Beta Linux
CPU Mining
For CPU mining I use minerd because it doesn't require any work to get running, simply download it and get to work. Download the built file for your machine 32-bit or 64-bit, and then unzip it and you're ready to go!
cd ~/Downloads tar -xvf pooler-cpuminer-2.3.2-linux-x86.tar.gz 
The executable is called minerd and it will be in ~/Downloads but you can move it to wherever you like. To run it, pull up terminal and do
cd ~/Downloads minerd --url=stratum+tcp://SERVER:PORT --userpass=USERNAME.WORKERNAME:WORKERPASSWORD 
You're done! Happy mining!
Common Issues
I ran into this and I've seen others with this problem as well. Everything installs fine but there is a shared library file that isn't where it should be. In fact, it isn't there at all.
 libudev.so.1: cannot open shared object file: No such file or directory 
In terminal, do
sudo updatedb locate libudev.so.0.13.0 
And it will probably return a path /lib/x86_64-linux-gnu. Inside that directory there's a library file called libudev.so.0.13.0. You'll need to make a symlink (aka shortcut) that links libudev.so.1 to libudev.so.0.13.0 So, assuming you're working with libudev.so.0.13.0 do this
cd /lib/x86_64-linux-gnu sudo ln -s libudev.so.0.13.0 libudev.so.1 
Now if you do
ln -l 
You should see
libudev.so.1 -> ./libudev.so.0.13.0 
Meaning you've made the symlink. Also, the text for libudev.so.1 will be blue.

Just the weirdest, most inexplicable sht I've ever dealt with in a rig. [PC, blackscreening, semi-random]

Hi all.
I'm utterly, utterly baffled. Stumped. Bemused. Befuddled. Bamboozled. I cannot explain this. At all.
I crash on my desktop, often (but not always) while opening Chrome. Crash can be 1m after boot, or 4 hours after boot. Machine blackscreens, stops responding, doesn't send anything to the monitor or respond to scroll lock or capslock.
Fairly standard - but I do NOT crash if there's a game running. Literally can run GW2 for as long as I need to, or warframe, or Titanfall, and it's solid as a rock.
I've arranged an RMA for my GPU as it's the most recent addition to the sytem (25 Feb 2014) and it was blackscreening on wake (but with a responsive PC/keyboard and the media server was still up), but I'm stumped. I've never seen anything like this.
What causes a rig to blackscreen when browsing or opening explorer, but doesn't have ANY problems when it's running high end games at max rez?
2500k @ 4.5GHz
R9 290 4GB Factory OC
700W Seasoninc PSU
1 SSD (OS + Games)
2 HDD (Stuff)
Midrange Gigabyte mobo, nothign special
8GB DDR3 @ 1600MHz
Win 8 64 Bit
etc etc.
EDIT: Memtest results are in. No problems found. Ran for 8 hours, zero errors.

Nuked 'em.
Wonder if I have (or hopefully had) a malware issue. GW2 is running in the background and it's still not crashed...
Ideas anyone? Am thinking about ordering a new CPU/Mobo and seeing if that fixes it - next on the list (after another crash) is going to be a W8 re-install.
OS re-installed and BIOS updated, still crashes. Definitely hardware. Definitely not RAM, definitely not storage (SSD or HDD). Crashes still independent of load - but most common when clicking on something (Firefox, Chrome or Evernote for example).
So the candicate list as far as I can work out is:
CPU (moderately likely, though stressing with linpack or OCCT or prime does not cause crashes, and it's happy while playing GW2) mobo (happy while gaming, unhappy when asked to execute a crappy little prgraom like Chrome. Weird? gotta be unlikely) PSU - Feeling like this is a likely candidate. GPU - but doesn't crash when rendering ~100 players at max res in GW2.
Soooooo.... can anyone think of a thing to test next?
Final edit: running on the onboard GPU on mah telly. Flawless, no crashes at all. I think it's the GPU, the 2D processing chip or whatever must've been borked.
Recap: new GPU, no crashes. All is now good!
