Multi Service Bus Core

Hi, this is a day I was looking forward for about two years. At least I am able to put here pre-release of the Multi Service Bus Core solution. It is pre-release because .NET Core 2.0 is still in preview2 stage. This is for me revolutionary code. It is something best I ever did. The C# piece of code that before even .NET Core start support WCF Service Host I am able to connect between Microsoft Windows, Continue ReadingMulti Service Bus Core

Generic Free Pattern Improved C#

Yes, I know that it is impossible to predict lottery results. But if the results would be predictable? Of course I know they are not, but just hypothetically for a play with Perceptron Neural Network and prediction algorithms I want to show you that in 250 lines of code you are able to play with prediction thanks to Encog 3.3 library. I bought recently 2 Jeff Heaton’s  books about neural network and C# and his library. That Continue ReadingPL Lotto Predictor in C# with Encog 3.3

Batch Processing Aspect in Java

Hi, today I made port of my Batch Processing Aspect in Java. It is quite a bit different aspect than I made previously in C#. In C# I made something that is fully asynchronous and in Java I made aspect that does sync invocations from many threads. I have in my mind uses of this aspect to web application or web api or web service implementation that has static controller field for example named “batchProcessingAspect” and invokes Continue ReadingBatch Processing Aspect in Java

Tutorial of MS SQL Extended Events in 7 T-SQL Steps

Hi, today I would like to show you how you can use Extended Events Sessions on SQL Server 2008 or above. Extended Event Sessions are future of monitoring of the SQL Server. From many years solutions that used SQL Profiler Traces or DMV were not always accurate and fast. DMV queries could be very fast. However it is impossible to get statistics only per one sessions from DMV. And that is why I want to show you Continue ReadingTutorial of MS SQL Extended Events in 7 T-SQL Steps

Simple Service Bus Training

Hi, today I prepared my first screencast trining on YouTube about the Simple Service Bus I made. It took me a lot of effort and it is just a start. If you like such content please share that information in comments. I would love to make more such videos in future. Here you can find ( downloads). Enjoy! p ;).

Using of TextWriter by StringBuilder

Hi, today I want to share with you very simple idea of using correctly TextWriter class. You can imagine that TextWriter is created on the network stream solution in SOA (WCF), REST (WebAPI) or Web (ASP.NET) application. When you write to that stream very often you could have a lot of unnecessary round-trips between clients and server. But there is nice technique with StringBuilder I want to share with you in below tests. I think nothing more Continue ReadingUsing of TextWriter by StringBuilder

SQL Ninja gets Products from Group Tree CTE

Hi, today I want to show you comparison of 2 possible techniques fro get data about all Products mapped to the Product Groups tree. I wrote as usual one T-SQL script that you can run each time you want to modify something to recalculate your results and check how they perform in your SQL Server. There are 2 nice things you can get from provided example. First is 2 ways of calculation that you can choose from. Continue ReadingSQL Ninja gets Products from Group Tree CTE
