In the previous post about Topshelf and Quartz.NET I mentioned that there is a chance to configure the inversion of control container instead of manually pointing which implementation we want to use. In this post, I will explain how to do just that, using a few popular inversion of control containers – Ninject and StructureMap. If you prefer any other container, please let me know. I’ll do my best to include it here. Plain projec...

I often work on applications whose sole task is to execute a script at certain time or day. You may approach it in several ways, eg.: Task Scheduler (Windows), SQL Job (if it is a SQL task) or CRON in Linux. You may also write application, which would run in background and execute a script at certain time. The only question is – do you really want do it? In this post, I would like to introduce other solution to tasks like this. ...

Amazon Web Services CloudSearch is a search engine and it’s offered in a SaaS model (as well as Elasticsearch what I’ve already explained here). I’m currently writing an article about it so I’ll skip the way how to set it up and how it works. Unfortunately, CloudSearch isn’t free. It doesn’t cost much if you take a look at everything what you get. For more information on pricing check here. There’s few issues with CloudSearch. One of them is ...

Often developers as a log store use text files, system events, output console or database. In some cases they use distributed systems such Splunk or Elasticsearch. In this article I would like to present how to store logs in the form of objects, rather than plain text, which also offers all sorts of graphs and charts called dashboards.

Przemysław Walkowski No w końcu znalazłem porządne i wygodne miejsce do codziennych ćwiczeń programistycznych – dostępne on-line i dość sensownie zrobione. Nie wielu programistów korzysta z takich rozwiązań. Nie wiem dlaczego. Jednak ja polecam codzienne ćwiczenia w pisaniu kodu i wymyślaniu algorytmów, bo tylko dzięki temu praktycznie zwiększymy szybkość pisania oraz będziemy elastycznie podchodzić do problemów. Jak to wygląda w praktyce napisze poniż...

Every experienced developer knows how important is to cover your code with tests (or at least business logic). However, not everyone likes to do that once code is already written, because, why should we do that? The work is done, it was tested and it functions correctly, right? I never liked to cover the code with tests once it’s already there. That’s why in this article I’ll present TDD and describe how I use it day to day.

Design patterns which I would like to present in this post are well described in the book Design Patterns. Elements of Reusable Object-Oriented Software  written by The Gang of Four (Gramma, Helm, Johnson, Vlissides). In my opinion this book is must read for every developer, regardless what programming language you are using. Besides the fact that this book was written more than 20 years ago, it still contains a lot of useful details for developers of all levels. I often revisit this book to keep in touc...
