[Solved] Massive data & Node.js – increasing timeout for request of REST API functions

In case of operations for big data regarding fetching numerous records, operations taking a bit time (e.g. > 3-5 minutes)  or uploading a blob on azure local storage even if we using async operations   node.js in this situations can close or reject current request due to exceed default timeout of request. In this situation we […]

[SOLVED] C# & HttpClient for SSL/TLS: Error The request was aborted: The request was canceled.

Sometimes our software that bases on HttpClient class requests has problem with connecting to services (AZURE or other portals) or REST API functions to https addresses (SSL). We’ve got error: “Error The request was aborted: The request was canceled.” and our connection is rejected at once. That can means that we should verify settings for TLS […]

Fuzzy Logic Controller on microcontroller in steering Air Conditioner – part I

I’d like present Fuzzy Logic Controller working on raw  microcontroller (without any OS) from practical point of view in steering Air Conditioner. Why raw microcontroller? Because I love challenges and implementation is much more sophisticated then in case of singleboard (e.g. raspberry) or computers, where we have installed operating system. In case of microcontroller engineer […]
