What Is Clean Code?

Reciteam "Clean Code" zilele astea și am dat peste definițiile date de către mai multi programatori a cea ce înseamna un cod curat. Mai jos găsiți aceste citate:
I like my code to be elegant and efficient. The logic should be straightforward to make it hard for bugs to hide, the dependencies minimal to ease maintenance, error handling complete according to an articulated strategy, and performance close to optimal so as not to tempt people to make the code messy with unprincipled optimizations. Clean code does one thing well.
Bjarne Stroustrup

Clean code is simple and direct. Clean codereads like well-written prose. Clean code neverobscures the designer’s intent but rather is fullof crisp abstractions and straightforward linesof control.
Grady Booch

Clean code can be read, and enhanced by adeveloper other than its original author. It hasunit and acceptance tests. It has meaningfulnames. It provides one way rather than manyways for doing one thing. It has minimal dependencies,which are explicitly defined, and providesa clear and minimal API. Code should beliterate since depending on the language, not allnecessary information can be expressed clearlyin code alone.
Dave Thomas

I could list all of the qualities that I notice inclean code, but there is one overarching qualitythat leads to all of them. Clean code alwayslooks like it was written by someone who cares.There is nothing obvious that you can do tomake it better. All of those things were thoughtabout by the code’s author, and if you try toimagine improvements, you’re led back towhere you are, sitting in appreciation of thecode someone left for you—code left by someonewho cares deeply about the craft.
Michael Feathers

In recent years I begin, and nearly end, with Beck’srules of simple code. In priority order, simple code:
• Runs all the tests;
• Contains no duplication;
• Expresses all the design ideas that are in thesystem;
• Minimizes the number of entities such as classes,methods, functions, and the like.
Of these, I focus mostly on duplication. When the same thing is done over and over,it’s a sign that there is an idea in our mind that is not well represented in the code. I try tofigure out what it is. Then I try to express that idea more clearly.
Ron Jeffries

You know you are working on clean code when eachroutine you read turns out to be pretty much whatyou expected. You can call it beautiful code whenthe code also makes it look like the language wasmade for the problem.
Ward Cunningham

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:

Entity Framework (EF) TransactionScope vs Database.BeginTransaction

In today blog post we will talk a little about a new feature that is available on EF6+ related to Transactions.
Until now, when we had to use transaction we used ‘TransactionScope’. It works great and I would say that is something that is now in our blood.
using (var scope = new TransactionScope(TransactionScopeOption.Required)) { using (SqlConnection conn = new SqlConnection("...")) { conn.Open(); SqlCommand sqlCommand = new SqlCommand(); sqlCommand.Connection = conn; sqlCommand.CommandText = ... sqlCommand.ExecuteNonQuery(); ... } scope.Complete(); } Starting with EF6.0 we have a new way to work with transactions. The new approach is based on Database.BeginTransaction(), Database.Rollback(), Database.Commit(). Yes, no more TransactionScope.
In the followi…
