"Could not contact node rabbit@[machine_name]" after upgrading to RabbitMQ 3.6.5

October 13, 2016

This error kept me busy for almost two days, so i thought it would be best to describe the steps i took to fix it Make sure that the erlang cookie file (.erlang.cookie) is configured correctly in all places. i.e. %HOMEDRIVE%%HOMEPATH% and %SYSTEMROOT%. it should contain the same value in all places Open the RabbitMQ command prompt with Administrator privileges Remove the RabbitMQ service by using the command: rabbitmq-service remove  Navigate to %APPDATA%\RabbitMQ\db Delete everything (make sure you have a backup just in case) Go back to the command promp and install the service with the command:...

Using Autofac Aggregate Services

September 13, 2016

I really like using Autofac, it’s one of the most productive libraries I know, and it’s so much fun to discover new features. Aggregate Services is Autofac feature that allows you to wrap a set of dependencies into a single aggregate without the need to implement a concrete type for it. Consider the following case where you have a base class that has dependencies on a few other services, and two derived classes: class BaseLicenseGenerator:ILicenseGenerator { //members public BaseLicenseGenerator(ILogger logger, IUserRepository userRepository, ILicenseRepository licenseRepository) { ...

New speaking engagement – Copenhagen .NET User Group

June 30, 2016

I’m very excited and greatful to be invited to speak at the Copenhagen .NET User Group (CNUG) on August 25th. If you’re around, come and meet me. You can register at:  I’ll do two sessions during the meetup: Reactive Extensions (Rx) 101 Reactive applications are designed to handle asynchronous events in a way that maximizes responsiveness, resiliency, and elasticity. Reactive Extensions (Rx) is a library that abstracts away the sources of events and provides tools to handle them in a reactive way. With Rx, filtering events, composing event sources, transforming events, and dealing with errors all...

Giving more memory space to 32bit process

January 20, 2016

Its fair to say that the standard CPU architecture that we all use these days is 64bit. But even though everyone has 64bit processor and 64bit windows, some processes are still 32bit. I’m currently working on a project that uses some 32bit 3rd party package, and because of that must also be build in 32bit. This project does a very heavy simulation and uses some very big geometric models that can take a large amount of memory. Because of the large models that the application needs to work with, there were times that we got OutOfMemoryExceptions.Obviously we...
