Visual Studio 2010: Find and Replace con Expresiones Regulares

Esto lo tienen versiones anteriores al Visual 2010, pero uso la referencia del 2010, así que aclaro por si las moscas.

Supongamos que tenemos una clase de test que abre un conjunto de archivos, y que tiene un montón de paths relativos hardcodeados de esta forma: 

class FactoryImage{

   public static IEnumerable ImageTestCases{

      get{
         //9 bits, Signed, Monochrome1
         yield return new TestCaseData(new ImageParameters {
            FileName = ".\\ImagesTest\\DavidClunie\\MONOCHROME1\\Signed\\9SignedMonochrome1_512x512_LE.pix", //Rawdata, example image
            FileNameWhite = ".\\ImagesTest\\DavidClunie\\MONOCHROME1\\Signed\\9SignedMonochrome1_512x512_LEWhiteImage.pix", //Rawdata, white example image
            //Otros atributos...
         });

         //9 bits, Unsigned, Monochrome1
         yield return new TestCaseData(new ImageParameters{
            FileName = ".\\ImagesTest\\DavidClunie\\MONOCHROME1\\Unsigned\\9UnsignedMonochrome1_512x512_LE.pix", //Rawdata, example image
            FileNameWhite = ".\\ImagesTest\\DavidClunie\\MONOCHROME1\\Unsigned\\9UnsignedMonochrome1_512x512_LEWhiteImage.pix", //Rawdata, white example image
            //Otros atributos...
         });

         //Muchas más sentencias yield...
     }
   }
}

Ahora supongamos que para ser más prolijos decidimos expresar los strings hardcodeados usando verbatim, o sea sin secuencias de escape, todo "literal". O sea, queremos hacer un reemplazo de este estilo: 

//Tenemos esto:
FileName = ".\\ImagesTest\\DavidClunie\\MONOCHROME1\\Signed\\9SignedMonochrome1_512x512_LE.pix",
//Y queremos convertirlo a esto:
FileName = @".\ImagesTest\DavidClunie\MONOCHROME1\Signed\9SignedMonochrome1_512x512_LE.pix",

Pero como tenemos muchas líneas así, cambiarlo a mano es muy engorroso. En un caso como este lo ideal es hacer un Find and Replace con Expresiones Regulares. Hay una referencia de la sintaxis que usa el Visual Studio acá. Luego de mirar un poco esa referencia, el reemplazo sale con estos patrones (click en la imagen para ver mejor):

Claro que no escribí todo el patrón de búsqueda y el de reemplazo y lo hice de una; es más práctico ir probando el patrón a medida que lo vamos escribiendo, para ver si matchea. Una vez que logramos que el patrón de búsqueda matchee bien, empezamos a escribir el de reemplazo y lo vamos probando de la misma forma.

VB.NET: Raise base class events from a derived class

Spanish version / Versión en Español Say we: Have a class we want to divide into subclasses The future base class has events The refactoring leads us to the need of raising an event declared in the base class, from a derived class. When we try to do point 3, we will get a compile error saying that a derived class cannot raise events from a base class. To get around this, we add a protected method in the base class which encapsulates the RaiseEvent call, and call that method from the derived class using MyBase. This way: In the base class (parameters as needed): Protected Overridable Sub OnMessageGenerated(ByVal NewSender As Object, ByVal NewMessage As String) RaiseEvent MessageGenerated(NewSender, New MessageEventArgs(NewMessage)) End Sub And in the derived class: 'Do stuff 'Raise base class event MyBase.OnMessageGenerated( Me, "Message" ) 'Do more stuff...

Apache Kafka - I - High level architecture and concepts

Image
Spanish version / Versión en Español First of all, what is Apache Kafka ? An initial definition for it is "a high-throughput distributed messaging system". Breaking this down a bit: High throughput: One of the main goals of Kafka is to process as much messages per unit of time as possible, in a scalable and fault-tolerant way. For example, LinkedIn , which is where Kafka originated, needs to achieve throughputs in the order of 20 million messages per second and 3 GB of data per second. Distributed messaging system: In a generic distributed system , networked computers work together for a common goal. In Kafka's case, that goal is to send data from points A 1 , A 2 , ... A N , to B 1 , B 2 , ... B M . A common benefit of this kind of system, which is crucial to Kafka's success, is horizontal scalability : the ability to handle higher and higher volumes of data by adding nodes to the system (not to be confused with  vertical scalability , whic

Upgrading Lodash from 3.x to 4.x

Spanish version / Versión en Español There are many breaking changes from version 3.x to 4.x; all changes are detailed in the Lodash changelog . There is also a list of deprecated functions , with a regex you can use to detect usages in your code. However, since it is not an exhaustive list, I will list the changes I encountered when performing my own migration, to help anyone undergoing the same process. Direct renames This section includes functions in which only the name changed, i.e. the arguments and return value are the same. 3.x 4.x contains includes first head rest tail invoke invokeMap padLeft padStart padRight padEnd Direct renames if not using thisArg This section includes functions in which the only change is dropping "thisArg". If you are not using it, you can just rename. If you are using thisArg in 3.x, it can be dropped if you are using iteratee to acce
