It is still possible to mine BEAM with GeForce GTX 1060 3GB and GMiner on HiveOS. GMiner takes 2862MB on GPU0 and 2850MiB on GPU1-7:
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/user/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 git reset --hard 1.1.2 mkdir build cd build/ cmake .. cmake --build . ./rippled -u
284.6s, 171 suites, 1049 cases, 379760 tests total, 0 failures
configured it and started:
cd ~ mkdir -p ~/.config/ripple cd ~/repos/rippled/ cp cfg/rippled-example.cfg ~/.config/ripple/rippled.cfg sudo mkdir -p /var/log/rippled/ sudo chgrp user /var/log/rippled/ sudo chmod g+w /var/log/rippled/ cd ~ mkdir /ripple-data nano ~/.config/ripple/rippled.cfg #set path in [node_db] to /home/user/ripple-data/node #set [database_path] to /home/user/ripple-data/db cp cfg/validators-example.txt ~/.config/ripple/validators.txt cd ~/repos/rippled/build ./rippled
and got something close to what is expected:

To enable the validation I built validator-keys-tool:
cd ~/repos git clone --recursive https://github.com/ripple/validator-keys-tool.git cd validator-keys-tool/ git submodule update --init --recursive mkdir build cd build/ export BOOST_ROOT=/home/user/lib/boost_1_67_0 cmake .. cmake --build . ./validator-keys -u
Then I generated the keys:
./validator-keys create_keys ./validator-keys create_token --keyfile /home/user/.ripple/validator-keys.json
added [validator_token] section to /home/xrp/.config/ripple/rippled.cfg and “pubkey_validator” matched the validator public key.

Setting up time synchronization on Ubuntu
I followed the official Ubuntu time synchronization guide and installed chrony:
sudo apt update sudo apt install chrony cat /etc/chrony/chrony.conf chronyc sources chronyc sourcestats sudo systemctl restart chrony.service apt remove --autoremove chrony
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).
Checking the speed of my home internet.
I have 50 Mbit internet at home. If I test its speed with speedtest.net I get download speed 56 Mbit/s and upload speed 5.56 Mbit/s that is really good:
and if I download a file with torrent the speed is 6+ MB/s, but if I download a file with HTTP or SFTP the speed can be less than 500 KB/s that is 10 times slower. For example, if I download Ubuntu 18.10 on my VPS the speed is 24 MB/s:
Setting up Vue.js development tools on Windows 10.
I installed Node.js and Vue.js cli with the following commands
npm install -g @vue/cli npm install -g @vue/cli-init
and a sample application with
vue init webpack-simple my-vue-app cd my-vue-app npm install npm run dev
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):
Molten SATA power connector on a mining rig.
I have a mining rig with 8 GTX 1060 3GB connected via risers, the risers are connected via SATA power connectors to Corsair HX850. When the rig stopped working I noticed that one SATA connector on the PSU is molten:
How I built QT 5.11.1 for Android on Windows
I tried to build QT 5.11.1 for Android on Windows, and “configure.bat” completed successfully, but “mingw32-make” failed with with the following error:
No rule to make target 'vulkan/qvulkanfunctions_p.h', needed by '.obj\qvulkaninstance.obj'.
It is the bug fixed in QT 5.11.2 that is planned on August/September 2018.
When I build the master branch and copied the following files from it to \qtbase\src\gui\vulkan manually:
qvulkanfunctions.h qvulkanfunctions_p.cpp qvulkanfunctions_p.h
and started “mingw32-make” again I got another error:
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)
