it is the best i did with the talent i had… for free…
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 not sure 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 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 are able to play with prediction thanks to EnCog 3.4 library. I bought recently 2 Jeff Heaton’s books about neural networks Continue ReadingEuroJackpot with EnCog ANN and Stats
Hi, today I am starting the new coding adventure that probably takes me few weekends. It will be IoT Platform PoC based on Multi Service Bus Core 2.0. I have got only one Raspberry Pi 3, and for PoC I plan use some small sensor, maybe for temperature in our home. I do not have sensor that is able to use MQTT, but I really want, so if you can borrow one Continue ReadingIoT Platform PoC
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 myself a very good tool to draw diagrams. Below I will want first to start with 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 Continue ReadingMulti Service Bus Core 2.0
Hi, today thanks to 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 possible to use on R Pi 3 for sensors for IoT my own service bus. The mentioned solution Multi Service Bus Core Continue ReadingMulti Service Bus Core on Raspberry Pi 3
Hi, today the .NET Core 2.0 was released, so I am very 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 tests results of this ready for IoT and Multi-Core coding library… I did not change anything in code from 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 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 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 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 Continue ReadingGeneric Free Pattern Improved C#
I feel really disappointed, because I have not received any solution form anyone, for this puzzle. Solution of this is very trivial with correct tools. Tool I am using to solve this is Simple Service Bus. I want to remind you what was the architecture design pattern. And below you can find very trivial and working solution. Can you explain why nobody solve this? Just wonder. The only thing I do not Continue ReadingCode Puzzle – Get Behind Firewall – Solution
Hi, today I have very nice code puzzle for you. Code Puzzle is to implement two blue boxes in following diagram. That can be implemented in Java and/or C# with following requirements. The only system that can receive connections is behind green box that is a open server endpoint. The system behind red box is closed and you cannot connect to it. I have very special prize for the best, clean and 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 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. 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 find 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) 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 comments. I would love to make more such videos in 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 process not working. So I wrote Performance Counter Logger to solve that issue. it is very small almost trivial tool which has 60 lines of C# code. 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 queue of messages and even some number of threads that in parallel get messages from queue and then there are doing background work. Now if that messages executes actions on relational database you will quickly find out that some of your work is done right, but because of some Continue ReadingParallelExecutorAspect in C#
