How to check .NET Framework version with WIX installer

WIX has NetFxExtension with NetFx4XXXX packages, so .NET Framework 4.6, for example, can be installed with the single line of code:

<?xml version="1.0" encoding="UTF-8"?>
<Wix xmlns="" xmlns:bal="" xmlns:netfx="">
    <Bundle Name="My App">
        <BootstrapperApplicationRef Id="ManagedBootstrapperApplicationHost">
            <Payload SourceFile="$(var.MySetupUI.TargetPath)"/>
            <Payload SourceFile="$(var.MySetupUI.TargetPath).config"/>
            <Payload SourceFile="$(var.MySetupUI.TargetDir)BootstrapperCore.dll"/>
            <Payload SourceFile="$(var.MySetupUI.TargetDir)BootstrapperCore.xml"/>
            <Payload SourceFile="BootstrapperCore.config"/>

            <Payload SourceFile="C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5\System.ServiceProcess.dll"/>
            <Payload SourceFile="C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5\System.Configuration.Install.dll"/>
            <Payload SourceFile="C:\Program Files (x86)\WiX Toolset v3.11\SDK\Microsoft.Deployment.WindowsInstaller.dll"/>

            <PackageGroupRef Id='NetFx46Web'/>
            <MsiPackage SourceFile="$(var.MyAppSetup.TargetPath)" Id="InstallationPackageId" Cache="yes" Visible="no"/>

Installing Google Play Services on a Windows 10 with MS VS2015

If Android support is enabled in MS VS2015, it installs Android SDK without Google Play Services and I did not find an option in SDK Manager that installs them. When I started “C:\Program Files (x86)\Android\android-sdk\SDK Manager.exe” with admin privileges, it automatically offered to install some 9 packages:

How I fixed 504 Gateway Timeout error on Nginx + PHP-FPM

Today I got 504 Gateway Timeout error while updating my Joomla website and solved this issue by adding “fastcgi_read_timeout 300” into Nginx virtual host:

location ~ \.php$ {
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_pass unix:/run/php/www-shar.sock;
    fastcgi_index index.php;
    include fastcgi.conf;
    fastcgi_read_timeout 300;

I already had request_terminate_timeout option set to 300s in the pool configuration file:

; The timeout for serving a single request after which the worker process will
; be killed. This option should be used when the 'max_execution_time' ini option
; does not stop script execution for some reason. A value of '0' means 'off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
request_terminate_timeout = 300s

Configuring Postfix with relay in Ubuntu 16.04

Today I read that Postfix can be better than sendmail and found a great Russian article on how to configure Postfix to work with relay ( is some kind of Russian Google). The only notice I would give is that in a Docker container I need also install rsyslog, otherwise /var/log/mail.log file is not created:

apt install rsyslog

After doing all the steps described in this Russian manual I was able to send email to and GMail accounts, but GMail landed all the emails to its spam folder. My first idea was that it is because I did not configure ‘from address’ correctly, so I had the following in /var/log/mail.log, and also there was a message ‘Cannot assign requested address‘:

Oct 27 11:36:19 0675c97b78aa postfix/pickup[1210]: 8C7ECE5B72: uid=0 from=<root>
Oct 27 11:36:19 0675c97b78aa postfix/cleanup[10786]: 8C7ECE5B72: message-id=<20171027113619.8C7ECE5B72@0675c97b78aa.localdomain>
Oct 27 11:36:19 0675c97b78aa postfix/qmgr[1211]: 8C7ECE5B72: from=<root@0675c97b78aa.localdomain>, size=405, nrcpt=2 (queue active)
Oct 27 11:36:19 0675c97b78aa postfix/smtp[10788]: connect to[2a00:1450:400c:c09::1b]:25: Cannot assign requested address


Configuring sendmail with GMail relay on Ubuntu 16.04

Previously I published post How I configured sendmail for PHP on Ubuntu Server 12.04 describing how to configure sendmail to use custom SMTP server. But after switching to Ubuntu 16.04 VPS my first idea was that I can use sendmail in its default configuration, but this idea was wrong, because while sendmail worked well with (some Russian mail server), for example, it did not work with GMail, because GMail did not accept the mail reporting ‘DSN: Service unavailable.‘ in /var/log/mail.log, see my post on Ubuntu Forum for more information. Now my second idea is that using GMail as sendmail relay will prevent GMail from rejecting my mail. Below I provided a short instruction on how to realize this successful idea.

Install the packages

apt-get install sendmail mailutils

mailutils allows to run mail command.


Fun with Bitcoin mining on a home Windows machine.

I have heard many times that there are a lot of Russian guys who build mining farms and earn money with cryptocurrencies. Who knows, probably cryptocurrencies are still only at the starting point of their growth, or probably it is too late to start mining, or as another alternative Russian government will forbid them, but anyway it was interesting for me, how much Bitcoins my home Windows computer with relatively old graphic card can mine.

I overclocked my GeForce GTX 750 graphics card a bit:
