My first experiment with a peak detection algorithm

Hi guys!

For those how are interested in what I am doing now I provided my app screenshots with ‘Find Peaks’ button that runs ZScore algorithm on a cryptocurrency market data (follow the this link for the algorithm source code in C++).

Honestly I am not quite enough understand yet how it works, because I run it first time today, but at least there is some correlation between input parameters and the results. The lesser the threshold and the longer the lag the lesser peaks are found. Increasing the influence also reduces the peak count.

Mining Raven Coin (RVN) with KawPow on Windows 10

I run T-Rex miner as follows:

t-rex -a kawpow -o stratum+tcp://rvn.2miners.com:6060 -u <mywallet>.rigW -p x

and set the following parameters on my 1060 GTX 3GB card with MSI Afterburner:

Building and running rippled on Ubuntu.

I successfully build and run rippled 1.1.2 on Ubuntu 18.04 with the following commands:

sudo apt-get -y install git cmake pkg-config protobuf-compiler libprotobuf-dev libssl-dev wget
cd ~Downloads/
wget https://dl.bintray.com/boostorg/release/1.67.0/source/boost_1_67_0.tar.gz
cd ..
mkdir lib
cd lib/
tar xvzf ~/Downloads/boost_1_67_0.tar.gz
./bootstrap.sh
./b2 -j1
export BOOST_ROOT=/home/xrp/lib/boost_1_67_0
cd ~/repos/
git clone https://github.com/ripple/rippled.git
cd rippled
git tag
git show --summary 1.1.2

Setting up Ethereum node on Windows 10 and Ubuntu.

After a few attempts I was able to start Ethereum Mist 0.11.1 in ‘fast’ mode on Windows 10:

it downloaded ‘geth’, connected to {“path”:”\\\\.\\pipe\\geth.ipc”} and started to sync, but when sync finished I was unable to send transactions (they were ‘denied’ for some reason).

Some GTX 1060 3GB cards have low hashrate with Ethash coins.

Ethash algorithm behaves a bit strange on my mining rig with HiveOS and 8 GTX 1060 3GB. Four MSI ARMOR cards with Sumsung memory (OC +1500 mem) have 24+ MH/s, two other cards (OC +600 mem) have 21+ MH/s and two other slow MSI cards (also OC +600 mem) have only 18+ MH/s. I tried to switch risers, PSU, PCI slots and move the cards across rigs, but with no success.

Today I did a pure experiment. I plugged one of the slow cards to a Windows 10 machine with 1000W PSU directly via PCI slot without riser, started Claymore Miner with Musicoin (that has a lower dag size than Ethereum) and got the same result as before, without OC the card had 15+ MH/s (normally it should be 19+ MH/s):

Mining Ethereum on Ubuntu 18.04 with GeForce GTX 1060 3GB

I am not a Linux expert, so it took me some time to configure my mining rig on Ubuntu 18.04 with NVIDIA GeForce GTX 1060 3GB, and I wrote down all the steps I did:

First I installed NVIDIA driver, but OpenCL did not install automatically with it and I installed it manually with the following command:

sudo apt install -y ocl-icd-libopencl1

Then I installed CURL:

sudo apt install -y libcurl3

not ‘curl’ and not ‘libcurl4’ packages, otherwise the miner will fail to start reporting the following error message:

./ethdcrminer64: /usr/lib/x86_64-linux-gnu/libcurl.so.4: version `CURL_OPENSSL_3' not found (required by ./ethdcrminer64)
