C++: Proyecto siempre desactualizado al correr en Visual Studio

Hace poco me pasó que compilaba mi aplicación exitosamente, pero al correrla el Visual Studio 2010 me decía que cierto proyecto estaba desactualizado y que si quería compilarlo. ¡Pero si acabo de compilarlo, macho!

Bueno, la solución es arremangarse y activar los mensajes de log del compilador de C++, algo que los de Mocosoft dejaron bastante oculto. Resumiendo:

  1. Probar haciendo un Clean Solution y compilando otra vez. Si eso no resuelve el problema, seguir al paso 2.
  2. Activar el logging para la compilación de proyectos C++.
  3. Bajar, descomprimir y ejecutar DebugView de, cuándo no, SysInternals. Unos capos.
  4. Agregarle un filtro al DebugView con el nombre de nuestro proyecto. Si no hacemos esto, nos ahogaremos en un mar de mensajes.
  5. Compilar de nuevo.
  6. Buscar un mensaje de este estilo: [42216] Project 'TuProyectoLoco.vcxproj' not up to date because build input 'TuDependenciaColgada' is missing.
  7. Borrar o corregir esa dependencia desde el Solution Explorer.
  8. Tomarse un trago (te lo has ganado...)

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
