W dokumentacji Microsoft przeczytamy, że Azure Service Fabric to platforma wspomagająca tworzenie, deployment oraz zarządzanie skalowalnymi i niezawodnymi mikroserwisami. Definicja jest nieco zawiła i mało obrazowa dla osób które wcześniej nie pracowały z podobnym rozwiązaniem. Co to właściwie oznacza? No cóż, zacznijmy od końca, czyli od pojęć “skalowalny” i “niezawodny”.

When it comes to writing maintainable UI test there always appears the term of Page Object Pattern. For those who are not familiar with Page Object, it’s the approach to building UI test that focuses on creating high-level abstraction over low-level details related to interaction with a tested application. This testing interface encapsulates all the noise related to technology and allows to clearly express intention of test cases. This concept is very well described...

One of my ideas for increasing productivity of my team with ELK was to integrate it with Microsoft Teams. I wanted to shorten the feedback loop between error occurrence and diagnosis phase by notifying development team about the issue right after of the occurrence through the dedicated Microsoft Teams Channel. In this blog post, I've described how to easily implement this integration.

Recently I’ve had occasion to work much more than usually with NHibernate. This is a really great ORM and a very mature project, but when you make a mistake it informs you about that in a very generic way (in most cases). The problem that hunted me for a few days was the issue with field length constrains (which was caused by insufficient and inconsistent REST API validation). When there was a discrepancy between declared field length in NHibernate mapping and validation logic (or the vali...

Some time ago I was trying to find a good extension to Chrome that would let me go to recent tab same as for example R# does it with files (or Alt+Tab for Windows). The outcome was rather poor so I decided to write my own extension (it’s called Omnicomplete). It does even more and is available on GitHub. Now I use it dozens of times a day and I can recommend it wholeheartedly.

Wersją roboczą nazywam pliki na którymi pracujemy, to te gotowe do zmiany. Zmiana gałęzi, zmiana HEAD naszego repozytorium powoduje również zmianę wersji roboczej. Zazwyczaj ta zmiana jest bardzo szybka, ponieważ git jest bardzo szybki, ale… im większe repozytorium i większe zmiany między wersjami, to czas potrzebny na przełączanie rośnie. Czasochłoność przełączania powiększy także IDE, bo zmiana plików projektowych pociągnie za sobą ekran konieczności przeład...

I’ve recently watched a pretty decent tutorial about DSC on Microsoft Virtual Academy. I’m not a huge fan of video tutorials because it always takes more time to watch them than read a book/blog post (you can hack it by increasing video speed and save yourself a couple of minutes) but sometimes there is additional beneficial side effect - the presenter can show you (accidentally or not) some tips and tricks not strictly related to the core subject of the video. This post is an attempt of summarizing tric...

Command linePosted on by chrisseroka in Command line Sometimes free disk space shrinks and you need to figure out the reason. Whenever it happened to me I remember downloading some tool to calculate size of subfolders and detect the weightest one. I felt that there must be a way of doing that without third-party tools but it lived a long life on my TODO list (not that obvious to google).

Some people used to say that a good programmer doesn’t need to debug his own code. However, sometimes we have a problem with third party libraries usage, for example: there is insufficient documentation or the module contains some bugs. Visual Studio has excellent debugging toolset but this is totally useless without symbols and sources (and this is often the case with third party libraries). Thanks to Reshaper decompiler this shouldn’t be a problem anymore. Before we start debugging we should make so...

Zawsze przychodzi ten moment gdy trzeba rozwiązać buga na produkcji i jedyne co mamy to logi aplikacji. Okazuje się oczywiście, że nie ma wszystkich informacji w tych logach. Nie ma nawet całkiem podstawowych informacji...
