TechEd 2013 - Pre-Conference Day

The pre-conference day of TechEd has finished. It was a full day with interesting seminars. For me, this morning was pretty hard to decide at what seminar I want to participate. I wasn’t decide what seminar to choose between “Enterprise Agility is Not an Oxymoron” and “Extending Your Apps and Infrastructure into the Cloud”.
In the end I decided to go to the second presentation, where I found out a lot of cool information related to this topic. In the next part of the post I will enumerate some interesting information that I discovered:

  • In this moment, most applications that are hosted on Windows Azure are ON AND OFF or PREDICTABLE BURSTING. To tell you the truth, I didn’t expected the ON AND OFF apps to be on top. 
  • Over 98% of organizations use and have virtualization. This is a huge opportunity for cloud providers.
  • Be aware of the SLA. If the provider cannot offer the uptime from SLA you will receive the money back for the downtime, but you will not recover the money that you lost during that period of time when your app or service is down.
  • You can find a SQL Server VM image on VM library that can be used on the cloud without having to buy your own license for SQL Server.
  • For VM you pay per minute and not per hour. First 5 minutes are free :-).

See you tomorrow night.

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:

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&#…

Fundamental Books of a Software Engineer (version 2018)

More then six years ago I wrote a blog post about fundamental books that any software engineer (developer) should read. Now it is an excellent time to update this list with new entries.

There are 5 different categories of books, that represent the recommended path. For example, you start with Coding books, after that, you read books about Programming, Design and so on.
There are some books about C++ that I recommend not because you shall know C++, only because the concepts that you can learn from it.
