HTML 5 - efecte vizuale uimitoare

Se pare ca zilele in care se folosea Photoshop la greu pentru a crea efecte pe paginile HTML incep sa apuna. Java Script impreuna cu HTML 5 ofera posibilitatea de a face efecte vizuale pe care acu 2-3 ani doar le puteam visa.
Hai sa va dau si un exemplu:
Este un site de benzi desenate. Nimic deosebit pana acuma. Dar daca ne uitam in codul HTML o sa observam ca foarte multe efecte vizuale la imagini sunt facute prin intermediul la Java Script.
Cum s-a ajuns la aceasta performanta? S-a inceput de la niste imagini in format PNG, care pot sa fie transparente sau "decupate". Prin acest mecanism se permite suprapunerea de imagini ca si in Photoshop( layer). Fiecare element din imagine este o imagine separata. Dar pe langa atributele normale care le putem gasi pentru tagurile HTML precum img sau p o sa observat niste atribute noi precum: cp:x, cp:ballon sau cp:text. Aceste atribute custom, prefixate cu cp pe care le-a introdus creatorul sitului nu sunt procesate de catre brower deoare nu sunt valide. Dar reprezinta un mod inedit de a pastra meta-date precum pozitie pe o anumita axa, fond type, efectul care sa existe pe tagul respectiv.
<p class="Balloon" cp:text="Little" cp:balloon="Tell" style="left: 74px; top: 35px; width: 280px; position: absolute">
He's come to the west; the land of opportunity.
<img class="Layer" style="left:-444px; top:-75px" src="soif-2.png" cp:y="100" cp:x="600" />

Dar fiecare din aceste atribute sunt prelucrate de catre Java Script care adauga anumite efecte speciale. Toate aceste efecte speciale le puteti gasii in parallax.js.

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:

Run native .NET application in Docker (.NET Framework 4.6.2)

The main scope of this post is to see how we can run a legacy application written in .NET Framework in Docker.

First of all, let’s define what is a legacy application in our context. By a legacy application we understand an application that runs .NET Framework 3.5 or higher in a production environment where we don’t have any more the people or documentation that would help us to understand what is happening behind the scene.
In this scenarios, you might want to migrate the current solution from a standard environment to Docker. There are many advantages for such a migration, like:

Continuous DeploymentTestingIsolationSecurity at container levelVersioning ControlEnvironment Standardization
Until now, we didn’t had the possibility to run a .NET application in Docker. With .NET Core, there was support for .NET Core in Docker, but migration from a full .NET framework to .NET Core can be costly and even impossible. Not only because of lack of features, but also because once you…
