Generic Free Pattern Improved C#

nyob zoo, some time ago I posted information about Generic Free Pattern, but I used there the reflection. Today I would like to share with you solution that is a way much faster. The source of creation a bridge between non-generic and generic classes is in the method named Creator. The usage of the pattern is at the end of the code. Where you can create class EntityManager that is non-generic but the logic that is called behind Continue ReadingGeneric Free Pattern Improved C#

PL Lotto Predictor in C# with Encog 3.3

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

nyob zoo, 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

Ntxuav cov nam hauv C# batch

nyob zoo, today I want to share with you idea of batch processing aspect. It solves an issue with calling T-SQL Server procedures 1-by-1 request for example for inserts calls. And instead of calling 1-by-1 I prepared aspects that you call 1-by-1 but it do it in batches for example up to 100-by-100 like in my test example. Below you can find a code that includes aspect and a simple test of it. The most important quality factor Continue ReadingNtxuav cov nam hauv C# batch

Action<T> and Func<T, TResult> in Java 8

nyob zoo, as a .NET/C# coder I found the issue that there is not Action<T> and Func<T, TResult> equivalents in Java environment. I am self-study this to prepare myself to the OCA certification and I had idea that I can use lambda expression and implement simple equivalents of C# delegates in the Java 8. Below you can find implementation with test cases. I found that the code can be very easy, because lambda expressions works as a anonymous Continue ReadingAction<T> and Func<T, TResult> in Java 8
