Recently, I have shown, how to enable Application Insights within own WCF server application (look here). It might similarly work in other kinds of apps, so we won’t bother with further demystification of this procedure. But as you might suspect (or already stepped on), you will quickly require more metadata transmitted than it is done by default.
My scenario is pretty simple. The WCF server is installed multiple times, in multiple physical locations across the whole country.
Read more →Here I would like to present a small recipe, that will let you enable monitoring of WCF server-side calls with Microsoft’s ApplicationInsights service. It might help you in analytics of:
what services are used mosts what hours users are active what are the response times what is called far too often and needs optimization and probably most important thing - what crashed, why, when with the callstack! It’s pretty straightforward and I split it into two parts.

Here are two simple steps to restore it. Only two - as I already had it enabled in my UEFI BIOS on the motherboard and also installed drivers for my build-in Intel network card 82579V.

Recently I discovered that on my build server resides Visual Studio 2010 with SP1. It occupies tremendous amount of space and at the first glance it was totally unnecessary to be there at all. So I had this brilliant though and immediately went to Control Panel and hit Uninstall. Which of course failed miserably after 20 minutes of processing. Then destroyed the hard drive even more with finalization that rolled back the whole procedure…

All you have to do, to make it work, is to download OpenSSL 1.0.xxx library for Windows from here and install to any folder (for example: “C:\OpenSSL”). The tiny 3MB package is enough. Then copy the libeay32.dll and libssl32.dll into developed applications folder (the output one) and it will be automatically picked up during startup.
Read more →Latest version of QtCreator out of the box installs only Qt 5.0+. That’s rather obvious, but what if someone wants to play a bit with previous edition? Yeap v4.8, the one that is almost 4 years old! It is still doable and I will shortly show the way. Move to TL;DR if you are not interested in the background story.
You could ask why I wanted to do that in the first place, so here is the reason.

By some reason my connection was always rejected with following error message:
The driver could not establish a secure connection to SQL Server by using Secure Sockets Layer (SSL) encryption. Error: “sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target”.

Till four months ago I was still using my 2011’ MacBook Pro with some additional upgrades done down the line (described them here and here). Nevertheless it was more often seen it became older and older and somehow the speed and work comfort was insufficient anymore. Once decision was made, for the first time in my life I wanted to buy my next laptop wisely.

This time I had a pleasure to wrap several HTTPS calls using libcurl. But how to make it run on my x64 Windows machine? There is some info on StackOverflow.com, what can be moved to VS2017 in following steps:
Start VS2017 console: ”%ProgramFiles(x86)%\Microsoft Visual Studio 14.
Read more →Recently I described, how to keep in sync with GitLab latest releases on the Raspberry Pi. And of course it lead me to a problem after unsuccessful update to version 8.17-rc3. This release has the PostgreSQL 9.6.2 embedded and apparently everything got broken in the middle of the upgrade process. After all my tries to revert to previous GitLab version, lots of time wasted (yes, each call to apt-get upgrade or install specified GitLab version was taking several hours!
