[Post Event] Cluj City Apps Hackaton 14-16 March 2014

This weekend in Cluj-Napoca we had the first hackathon based on public data offered by Cluj-Napoca City Hall. There were a lot of public data that could be used to create different application. For example people had access to data related to parking slots, how European funds are used and so on.
This event was organized by Cluster Cluj IT in collaboration with Microsoft Romania, Cluj-Napoca City Hall and hosted by City Hub. At this event I was invited as mentor and to be part of the jury.
I saw a lot of great ideas that could be used in everyday life to improve our life. There were a lot of application around maps and putting different data on the map. A lot of teams tried to add content to the map and on different graphical reports.

A small hint for all teams for the next time when they have an idea related to this. Try to look on the internet and find out what kind of frameworks you can use in your application. THE internet is full with free stacks and application that can be used for this scope. It is better to be an integrator of different services and frameworks than to develop an application from scratch (cheaper, fuster and better).
For example, Office 365 BI Power Tools give you the possibility to make queries over data, filter them, put this data on the map, create complex models using pivots and different views and many more.

It was pretty great to select what application is the best. I hope that in near future to see all of them online or in the store, especially because the city hall said that they will substation them. I would really enjoy using all of them in real life. The quality of people life from Cluj-Napoca would be improves a lot if all this application will be published.

How to check in AngularJS if a service was register or not

There are cases when you need to check in a service or a controller was register in AngularJS.
For example a valid use case is when you have the same implementation running on multiple application. In this case, you may want to intercept the HTTP provider and add a custom step there. This step don’t needs to run on all the application, only in the one where the service exist and register.
A solution for this case would be to have a flag in the configuration that specify this. In the core you would have an IF that would check the value of this flag.
Another solution is to check if a specific service was register in AngularJS or not. If the service was register that you would execute your own logic.
To check if a service was register or not in AngularJS container you need to call the ‘has’ method of ‘inhector’. It will return TRUE if the service was register.
if ($injector.has('httpInterceptorService')) { $httpProvider.interceptors.push('httpInterceptorService&#…

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

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 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:

[Post-Event] Codecamp Conference Cluj-Napoca - Nov 19, 2016

Last day I was invited to another Codecamp Conference, that took place in Cluj-Napoca. Like other Codecamp Conferences, the event was very big, with more than 1.000 participants and 70 sessions. There were 10 tracks in parallel, so it was pretty hard to decide at  what session you want to join.
It was great to join this conference and I hope that you discovered something new during the conference.
At this event I talked about Azure IoT Hub and how we can use it to connect devices from the field. I had a lot of demos using Raspberry PI 3 and Simplelink SensorTag. Most of the samples were written in C++ and Node.JS and people were impressed that even if we are using Microsoft technologies, we are not limited to C# and .NET. World and Microsoft are changing so fast. Just looking and Azure IoT Hub and new features that were launched and I'm pressed (Jobs, Methods, Device Twin).
On backend my demos covered Stream Analytics, Event Hub, Azure Object Storage and DocumentDB.

What abo…
