[IoT Home Project] Part 1 - Initial Setup

By
I started some time ago to play with Raspberry PI and GrovePI sensors. After playing for a few weeks I said that I need to do something more interesting.

Mission
Why not combine Raspberry PI and GrovePI sensors with Azure IoT Suite and detect if somebody is at the desk, show STOP sign if the given person is busy and so on. I'll start with very basic use-cases, that will evolve in time. The scope of the projects is to learn different technologies that can be used together

Raspberry PI configuration
The code that will run on Raspberry PI will not be to complex, or this is what I expect now (smile). In this context it doesn't make sense to try to use Windows IoT. Also, the support for GrovePI is better for Node.JS in comparison with .NET.
In the context of my past experience with Debian on Raspberry PI that was good I decided that I will use Debian on Raspberry PI.

Development Environment
First thing is to make the initial setup of development environment. For backed, the story is pretty simple. We can use easily Visual Studio 2015 or Visual Studio Code.
Initially I wanted to run Visual Studio Code on my development machine and do a remote deployment on Raspberry PI. Because Visual Studio Code supports Remote Debugging for Node.JS, this should be pretty simple.

But, why not run Visual Studio Code directly on Raspberry PI. There is already support for ARM processors... so why not?
A few months ago there was a nice post from Scott Hanselman that describes how you can build your own build of Visual Studio for Raspberry PI - http://www.hanselman.com/blog/BuildingVisualStudioCodeOnARaspberryPi3.aspx 
Meanwhile, Jay Rodgers created an automatically night build that created builds of Visual Studio Code for ARM - https://code.headmelted.com/. In this way, only with a few clicks we can have Visual Studio Code installed on our Raspberry PI.


GrovePI Setup
The hardware setup is not complex. If you follow the steps from their web site or from the instruction book that comes with GrovePI box, you'll not have any kind of problems. Now, it is a good moment to take run a sample of an application written for GrovePI. Any kind of problems (hardware or software can be detected easily.

Next
The next step will be to attach the temperature and humidity sensor to the board and display the information to the LCD.

How to audit an Azure Cosmos DB

By
In this post, we will talk about how we can audit an Azure Cosmos DB database. Before jumping into the problem let us define the business requirement: As an Administrator I want to be able to audit all changes that were done to specific collection inside my Azure Cosmos DB. The requirement is simple, but can be a little tricky to implement fully. First of all when you are using Azure Cosmos DB or any other storage solution there are 99% odds that you’ll have more than one system that writes data to it. This means that you have or not have control on the systems that are doing any create/update/delete operations. Solution 1: Diagnostic Logs Cosmos DB allows us activate diagnostics logs and stream the output a storage account for achieving to other systems like Event Hub or Log Analytics. This would allow us to have information related to who, when, what, response code and how the access operation to our Cosmos DB was done. Beside this there is a field that specifies what was th...

Can User Technical Profile Influence AI Architecture Decisions?

By
In the last few days, I ran a small experiment on Devin/Windsurf/Cascade, BMAD, and LLM-based architecture decisions. The initial concern was simple: if an AI coding assistant knows something about the user, for example, that the user is a Java developer or a .NET developer, can this information influence the architecture and technology stack that the AI will propose? This question is important because many companies are starting to use AI tools not only for coding but also for product discovery, architecture, documentation, and technical decision-making. If the AI is influenced by the developer's personal profile, the result may not be fully neutral. It may look like a business or architecture decision, but in reality, it may be partially shaped by the context of the person using the tool. The test was done using BMAD with Devin/Windsurf/Cascade. The scenario was a unified field service operations platform. The task was to let BMAD refine the product, define the architecture and s...

ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded

By
Today blog post will be started with the following error when running DB tests on the CI machine: threw exception: System.InvalidOperationException: The Entity Framework provider type 'System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer' registered in the application config file for the ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded. Make sure that the assembly-qualified name is used and that the assembly is available to the running application. See http://go.microsoft.com/fwlink/?LinkId=260882 for more information. at System.Data.Entity.Infrastructure.DependencyResolution.ProviderServicesFactory.GetInstance(String providerTypeName, String providerInvariantName) This error happened only on the Continuous Integration machine. On the devs machines, everything has fine. The classic problem – on my machine it’s working. The CI has the following configuration: TeamCity .NET 4.51 EF 6.0.2 VS2013 It see...
