Renovación y limpieza del blog - Nuevo coloreado de sintaxis

Al pasar a un tema de Blogger más moderno, perdí el coloreado de sintaxis provisto por el plugin Syntax Highlighter de Alex Gorbatchev, proyecto que sigue vivo al día de hoy pero por alguna razón que no logré dilucidar, no funciona con los nuevos temas dinámicos de Blogger.

Investigando un poco, me topé con Highlight JS, y me gustó su simpleza y versatilidad. No tiene números de línea, pero como su creador explica, no son imprescindibles y realmente se ve mucho mejor.

Para instalar Highlight JS en un blog de Blogger, se requieren 3 simples pasos:

  1. Ir a Tema-Editar HTML y agregar links al CSS y JS de HighlightJS dentro de <head>. Por ejemplo, usando los de CDNJS para la versión 9.10: 
    <link href='//cdnjs.cloudflare.com/ajax/libs/highlight.js/9.10.0/styles/tomorrow-night.min.css' rel='stylesheet'/>
<script src='//cdnjs.cloudflare.com/ajax/libs/highlight.js/9.10.0/highlight.min.js'/>
    Yo estoy usando un estilo (Tomorrow Night) que no es el estándar; hay muchos más disponibles en CDNJS.
  2. Agregar, dentro del <body> del template, una llamada para aplicar el coloreado: 
    <script language='javascript'>
   hljs.initHighlightingOnLoad();
</script>
  3. El plugin de Gorbatchev formateaba usando sólo el tag <pre>. HighlighJS usa <code> dentro de <pre>: 
    <pre>
<code>
//Tu código acá
</code>
</pre>
    El lenguaje es reconocido automáticamente por HighlightJS. Pero como eso no es 100% exacto, a veces es necesario especificar el lenguaje. Eso se puede hacer usando el atributo class del tag <code>. La lista de lenguajes está aquí. Por otro lado, HighlightJS trae los lenguajes más comunes por defecto, pero soporta muchos más si se agregan manualmente. Además, es posible agregar lenguajes y estilos: véase la documentación.

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
