I think you should not overrate this 51% attack: http://www.youtube.com/watch?v=Lx9zgZCMqXE . As I understand it, when one node gets close to the 50% you can start scamming, but this does not mean, that someone is able to create coins, you just can change the addressee off a made transaction.  And: feelleeps pool itself is a powerful node, and now the second powerful one is surfer: so if you want to get rid of this 51% attack problem, we need more pools or single nodes with a lot of hashpower.

I'm still a noob, but I thought cgminer can handle rpc, what makes it to my opinion very attractive (no pool needed to mine with gpus ->hashpower better distributed over the nodes: so exactly what we need at the moment )

CGMiner integration - 1850 SKC +250 SKC
Pools - 1000 SKC + 250 SKC

ok got the same problem with looked acc.

Maybe we should donate him some skeincoins, so that he can collect some experience with this magnificent currency  ...

(p.s: i would provide 500 SKC for such a collection )

Skeincoin ++1

thank you very much

can someone tell me how is the owner of www.blakecoinpool.org or at least post his email address. My account is locked, and there is no contact given on the support page.

I saw that we can deposit again ... So is OpenEx "reopened" ?

... On twitter he said he has to take a sleep.

I really wonder where all this bad experiences come from. Ok my first account seemed to be deleted, but I had no deposits on that, and so that was ok for me. With my second account absolutely everything worked smooth. No problems in deposits. Trading was in the beginning a little buggy, but worked fine. I opened up to five support tickets now, and i got answer within 30 min to 3h for all of them.

Come on guys, it's not a project with a hundreds of thousand dollars startup budget, and: where are the good feelings come from when there is no improvement ?...  

what's the text in the right upper corner on openex.pw, that looks a little bit like a dashed line ?

edit: Ok i got it ^^ it's the text of missing text of the trading box below

It tested your new code with a HD 5850 over night:

old: 91Mh/s (estimate on share ratio) @ 67°C
new:88 Mh/s(estimate on share ratio) @ 63°C

core running at 900 Mhz, memory at 400 Mhz

So it seems to give comparable hashrates, but the work load of my gpu seems to be less. I will repeat this with a different memory clock speed hopefully today ( I want to install the temp sensing module before doing so)

P.s.: nice work!

In this sense I thought it's maybe not spamming to give some guide how I could setup the poclbm miner from the beginning on an fresh ubuntu when using an amd gpu.
That maybe not a new future by Ubuntu, but as a windows user I was absolutily impressed that one can directly install and also uninstall ubuntu in windows on a windows partition.

I am using Ubuntu 12.04 64bit and a HD 5850:

Install AMD-catalyst for linux 64bit:
        1) get AMD-catalyst, extract, and go to extraction folder
        2) "sudo sh ./AMD-<blablabla>.run"
        3) restart: "sudo shutdown 0 -r"

Install AMD-APP-SDK:
        1) get AMD-APP-SDK, extract and go to extraction folder
        2) "sudo sh ./Install-AMD-SDK.sh"
        3) restart: "sudo shutdown 0 -r"

Packages I installed making pyopencl "make" running (compilation) using
"sudo apt-get install <packages>":
        1) python-mako (I do not know if this is really needed)
        2) python-setuptools
        3) ipython
        4) python-numpy (I do not remember, if this was already installed)
        5) g++
        6) libboost-all-dev (I could not install this packs in the first place, but after installing "aptitude" to find the problem, the problem was solved)
        7) subversion (I do not know if this is really needed)

download and extract pyopencl from "https://pypi.python.org/pypi/pyopencl", go to extraction folder then:
        1) "python configure.py --cl-inc-dir=/opt/AMDAPP/include --cl-lib-dir=/opt/AMDAPP/lib/x86_64 --cl-libname=OpenCL"
        2) "make"
        3) " sudo make install"

get poclbm-skc source and compile skeinhash lib:
        1) "git clone https://github.com/snoopcode/poclbm-skc.git"
        2) "cd poclbm-skc\skeinhash"
        3) "gcc -fPIC -shared -o skeinhash.so *.c"

go back to poclbm main folder and check funtionality of poclbm:
        1) "ipython"
        2) "run poclbm"
        3) The output shows your GPU devices ... maybe you have different devices on diffrent platforms try: "run poclbm --platform=<platformID>"
        4) restart ipython: "exit()"-> "ipython" (if I don't do that I get an error)
        5) "run poclbm --platform=<platformID>  --device=<deviceID> stratum://<login>.<workername>:<passwort>@skc.coinmine.pl:6400"

skeinhash lib is compiled? the ctypes modul is installed? ... maybe copy the lib "skeinhash.so" directly in the poclbm-skc folder and get rid of all the folder stuff in the "skeinhash.py", meaning replace: "_shlib = ctypes.CDLL('./skeinhash/skeinhash.so')"  by "_shlib = ctypes.CDLL('skeinhash.so')"

Yes, that's exactly what I was searching for, Thanks! ... A new piece in the puzzle ...

So I tried the approach by reorder, but I still stuck with embedding the skeinmidhash-function in python:
 I found all the flakes needed for the lib that includes the skeinmidhash-function, I could compile the lib and I can access the function via python.
But I have no glue how to the access the output of the skeinhashmid function in python, like it has been defined in former posts by reorder.


So my question to you reorder is:

Can you give me/us please some more hinds how to embed your functions into python using your ctypes wrapper.

I think it would be very helpful for this coin to have a working  and easier accessible gpu implementation, because this would lift the interest for a broader spectrum of people.

Sorry but I have to disagree with you:

As it seems there is no hidden miner making 1000SKC/h or what ever with his GPU; this you can find out by just comparing some numbers:
There is only one pool mining a signifant amount of SKC on "coinmine" ( 24200 coins per day that is roughly the 32 SKC per 2min).
Top miners now mine with 10-27 Mh/s. My simple now already nearly 3 years old notebook, with a i7 reaches arround
1,2 Mh/s. So with some high end machine and - lets say- a bit affinitly 10 Mh/s is totally ecspectable.

I also think you cannot compare Skeincoins to XenCoin, because:
XenCoin had been premined (5% = 105mln coin allready in the beginning ); I think this is always bad
if you want to have a currency with high value and trust, when there are a lot of alternatives.
And the generation rate of XenCoins is 37.5 times higher (200 XenCoins per 20 sec vs. 32 SkeinCoinds per 120 sec)

I would say that's exactly the case: because every batch coming onto the market, will create a rise in difficulty making mining less efficient, and this will apply even more the latter you get your miner. In that tenor I would exspect, that for the asic developers it's a really big buisness, just by "testing" there devices and selling them. I dont want to say that you won't earn money with your device then, but at least without an intensive investment of money you wont be able to skip working, sit back, relax and let your miner printing money. At the moment it seems at least to me more efficient to mine alternative crypo coins and hope for a possible increase in value, than buying a asic miner for bitcoins.
