Event Sourcing with CQRS.

The way event sourcing works with CQRS is to have part of the application that models updates as writes to an event log or Kafka topic . This is paired with an event handler that subscribes to the Kafka topic, transforms the event (as required) and writes the materialized view to a read store.

Procedure to enable wireless LAN adapter in vmware!

I have went to find the way in which wlan in Kali Linux could be made listed my airmon-ng command. Most of the videos and posts suggested me that it is necessary to have another wi-fi adapter to have connected to wifi network. But this is not necessary. The procedure to do this is as follows: 1. Download this package in Virtual Machine(Kali linux) " http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2010-06-26-p.tar.bz2" 2.Unzip this package in terminal i.e navigate to place where you have downloaded this file , say desktop then type : cd Desktop for unzip type : tar -jxvf compat-wireless-2010-06-26-p.tar.bz2 3. Navigate into the uncompressed directory and type: i."make unload" (only words within the quotes are the commands) ii."make load" Done! now airmon-ng should have the list of the required devices.
