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:
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
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):
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:
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:
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)
Below I wrote down a simple PHP script that saves client IP address to a file. If the IP address of your home machine periodically changes, you can store it on a web server once a minute by scheduling a task like this:
sudo crontab -u <user> -e
* * * * * wget -q -O /dev/null -o /dev/null "https://yourwebsite.com/ip.php?rig=rig1&password=XXXXX"
where ip.php is the following PHP script:

I installed Perl, downloaded and extracted OpenSSL 1.1.0h and built 64 bit version in VS2015 x64 Native Tools Command Prompt with the following commands:
set PATH=%PATH%;C:\Perl64\bin perl Configure VC-WIN64A no-asm nmake
32 bit version can be built with VC-WIN32 configuration option as described in INSTALL:
on Windows (only pick one of the targets for configuration):
$ perl Configure { VC-WIN32 | VC-WIN64A | VC-WIN64I | VC-CE }
$ nmake
$ nmake test
$ nmake install
probably ‘A’ suffix means AMD and ‘I’ means something else, so we need ‘A’.
On some Windows 10 machine with IIS 10 installed I have three Microsoft.Web.Administration.dll:
Two versions 7.0.0.0 and 7.9.0.0 in GAC (C:\Windows\assembly\GAC_MSIL\Microsoft.Web.Administration\) in 7.0.0.0__31bf3856ad364e35 and 7.9.0.0__31bf3856ad364e35 folders respectively and one version 7.0.0.0 in C:\Windows\System32\inetsrv\.
The following XML element in a Visual Studio project file adds a reference to version 7.0.0.0 of Microsoft.Web.Administration.dll:
<Reference Include="Microsoft.Web.Administration, Version=7.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
<HintPath>%WINDIR%\System32\inetsrv\Microsoft.Web.Administration.dll</HintPath>
<Private>True</Private>
</Reference>
The same XML element with SpecificVersion=False will automatically reference the highest available version on this machine that is 7.9.0.0.
The following regular expression (find/replace pair) in Visual Studio format removes extra whitespace and @ symbol from a DEF-file:
^[ \t]+(\b(?<name>_\w+|[\w-[0-9_]]\w*)\b)[ \t]+@(?<index>\d+)(?=\r?$)
${name}\t${index}
and converts it to such a form when it can be imported to MS Excel and sorted by the function number, so you can manually add new functions by incrementing the last number.
To convert the file back the following find/replace pair can be used:
^(\b(?<name>_\w+|[\w-[0-9_]]\w*)\b)[ \t](?<index>\d+)(?=\r?$)
\t${name}\t\t@${index}
