Hi, my dear readers. Today I would like to tell you three technical stories. It will be stories with a happy ending… and you know me..? I am unsure if that story happens precisely this way, but the story is true. IoT Idea Story ;-). First of all, you probably know my passion for IoT? And also, as a tool builder, sorry to say, I do not like to buy the software Continue ReadingGPU-Computing for Vision Recognition Platform as IoT→
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 256 😉 Lines of code you can play with prediction thanks to the EnCog 3.4 library. I recently bought 2 of Jeff Heaton’s books about neural networks Continue ReadingEuroJackpot with EnCog ANN and Stats→
Hi, I am starting a new coding adventure that probably takes me a few weekends. It will be IoT Platform PoC based on Multi Service Bus Core 2.0. I have only one Raspberry Pi 3, and for PoC, I plan to use a small sensor, maybe for the temperature in our home. I do not have a sensor that can use MQTT, but I really want, so if you can borrow one Continue ReadingIoT Platform PoC→
Hi, today I want to present Multi Service Bus Core 2.0. The new version has a lot of small bugs fixed. I recently bought myself an excellent tool to draw diagrams. Below I will want first to start by showing the concept diagram. Multi-Service Bus Core 2.0 offers Server-Client communication. It is an important point, so I described it first with this but let me start from the basics principles of the Continue ReadingMulti Service Bus Core 2.0→
Hi, today thanks to a solution that I found on the Internet named Setting up Raspian and .NET Core 2.0 on Raspberry Pi I was able to configure .NET Core 2.0 and Multi Service Bus Core on the Raspberry Pi 3. This is a kind of PoC – Proof-of-Concept that makes it possible to use on R Pi 3 for sensors for IoT my own service bus. The mentioned solution Multi Service Continue ReadingMulti Service Bus Core on Raspberry Pi 3→
Hi, today, the .NET Core 2.0 was released, so I am happy to announce that Multi Service Bus Core is now ready for production. I developed it on macOS Sierra 10.12.6, and below, you can find the test results of this ready-for IoT and Multi-Core coding library… I did not change anything in the code from the last post about Multi Service Bus Core, so you can download it from that post Continue ReadingMulti Service Bus Core Released→
Hi, this is a day I have been looking forward to for about two years. At least I can put here a pre-release of the Multi-Service Bus Core solution. It is a pre-release because .NET Core 2.0 is still in the 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 started supporting WCF Service Host, I Continue ReadingMulti Service Bus Core→
Hi, some time ago I posted information about Generic Free Pattern, but I used there the reflection. Today I would like to share with you a much faster solution. The source of creation is a bridge between non-generic and generic classes in the Creator method. The usage of the pattern is at the end of the code. Where you can create a class EntityManager that is non-generic, but the logic that is Continue ReadingGeneric Free Pattern Improved C#→
I feel really disappointed because I have not received any solution from anyone for this puzzle. The solution to this is very trivial with the correct tools. Tool I am using to solve this is Simple Service Bus. I want to remind you what was the architectural design pattern. And below you can find very trivial and working solution. Can you explain why nobody solves this? Just wonder. The only thing I Continue ReadingCode Puzzle – Get Behind Firewall – Solution→
Hi, I have a very nice code puzzle for you today. Code Puzzle is to implement two blue boxes in the following diagram. That can be implemented in Java and/or C# with the following requirements. The only system that can receive connections is behind the green box, which is an open server endpoint. The system behind the red box is closed, and you cannot connect to it. I have an extraordinary prize Continue ReadingCode Puzzle – Get Behind Firewall→

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 requests, for example, for inserts calls. And instead of calling 1-by-1, I prepared aspects that you call 1-by-1, but it does it in batches, for example, up to 100-by-100, like in my test example. Below you can find a code that includes aspects and a simple test. The most Continue ReadingBatch Processing Aspect in C#→
Hi, today I would like to share with you new training about some breakthrough database code test tool named DbTester. I have never found anything similar that can help me with T-SQL performance tune-up, so I wrote it by myself, and I would like to share with you training about it. Solution itself uses Extended Events Sessions for monitoring and it works pretty well I think. Here you have ( downloads) for Continue ReadingBreakthrough DbTester Solution and Training→
Hi, today I prepared my first screencast training 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 the comments. I would love to make more such videos in the future. Here you can find ( downloads). Enjoy! p ;).
Hi, today I would like to share with you idea of the Performance Counter Logger. This tool is for logging performance counters values, and it solves issues with built-in PerfMon in Windows that collect data only for some time window and cannot auto-pause when the process not working. So I wrote Performance Counter Logger to solve that issue. It is a minimal, almost trivial tool with 60 lines of C# code. The Continue ReadingPerformance Counter Logger→
Hi, today I would like to share with you idea of right parallel execution of actions/methods. Imagine at the beginning that you have a queue of messages and even some threads that, in parallel, get messages from the queue and then do background work. If that message executes actions on the relational database, you will quickly find that some of your work is done right. Still, you get timeouts, deadlocks, or any Continue ReadingParallelExecutorAspect in C#→
