Hi, today I would like to show you how to solve the code puzzle with the time line. Where you have to in O(n) determine how many maximal events happen the same time… I hope you like it ;-). I looked on the Internet and there is no correct solution for this problem in my opinion, so far. So I decided to write on my own this solution and share with my readers… On the Internet there Continue ReadingHackerRank Customer Service Capacity
Hi, today I want to present to you Multi Service Bus Core 2.0. The new version has a lot of small bugs fixed. I recently bought to myself very good tool to draw diagrams. Below I will want first starting with showing the concept diagram. Multi Service Bus Core 2.0 offers Server to Client communication. It is important point so I described it first with this but let me start from the basics principles of the library Continue ReadingMulti Service Bus Core 2.0
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
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
Hi, 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 ReadingBatch Processing Aspect in C#
So, I did it :P. p ;).
Hi, I am happy to announce, that my learn Java journey at the Hacker Rank is going very nice. Today I was very happy to solve the code puzzle named Java 1D Array (Part 2) and this puzzle has already 39.64% success rate. And it category Data Structure Challenges most of the code puzzles has more than 90% of success rate. So far, so good, I have in Java 313 points and 2067 rank :). I have Continue ReadingLearn Java so Far so Good Java 1D Array
Hi, some time ago I started learn Java language. I ma trying to self-study learn of the Java. And I have to say that the language is very nice and with deep knowledge of C# my progress is fast. I want to show you today here one of nice code puzzle solution named Tag Content Extractor. It take me some time. I started learn Java from very easy puzzles and every next one is more and more Continue ReadingLearn Java proof at Hacker Rank in Tag Content Extractor
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
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 ;).
Hi, today I want to show you simple technique which can be used when you need parameterised ORDER BY cause in T-SQL. Sometimes you may want to have elegant query. Example is from my today’s code review that I gave to colleague. On the Internet is very difficult to find such solution. So, I decided to show it to you here. There are many possible scenarios for this example usage. For example you may want to have Continue ReadingSQL Ninja uses ORDER BY with CASE
Hi, I started today Multi Service Bus (GIT repo) project. Already I have full C# implementation. And I will be working on other languages implementations. First on Java and than on C++. I have some ideas how to made this in Java, but overall I am not Java expert, only C# expert, so that may be a bit difficult at the beginning. But I will be working on this, even if I do not know how. Of Continue ReadingMulti Service Bus Project Launch
