Lab: Consul and Network Partitions

  • Questions:
    • How does Consul behave in the different parts of a cluster during a network partition? Will it recover by itself when the partition is gone?
    • Would Consul change the Raft Leader if the current leader won't be able to communicate with some nodes while some other node will?
    • How does Consul perform in a lossy network?
  • Requirements: Vagrant, VirtualBox

Effective F#, tips and tricks

Architecture

  • Use Onion architecture

    • Dependencies go inwards. That is, the Core domain doesn't know about outside layers
  • Use pipeline model to implement workflows/use-cases/stories

    • Business logic makes decisions
    • IO does storage with minimal logic
    • Keep Business logic and IO separate
  • Keep IO at edges

DDD in golang

This is my response to an email asking about Domain-Driven Design in golang project.

Thank you for getting in touch. Below you will find my thoughts on how golang works with DDD, changing it. This is merely a perception of how things worked out for us in a single project.

That project has a relatively well-known domain. My colleagues on this project are very knowledgeable, thoughtful and invested in quality design. The story spelled out below is a result of countless hours spent discussing and refining the approach.

Conclusions could be very different, if there was a different project, team or a story-teller.

Routing tips for VPNs on OS X

Routing tips for VPNs on OS X

When VPNs Just Work™, they're a fantastic way of allowing access to a private network from remote locations. When they don't work it can be an experience in frustration. I've had situations where I can connect to a VPN from my Mac, but various networking situations cause routing conflicts. Here are a couple of cases and how I've been able to get around them.

Specific cases

Case 1: conflicting additional routes.

In this example the VPN we are connecting to has a subnet that does not conflict with our local IP, but has additional routes that conflict in some way with our local network's routing. In my example the remote subnet is 10.0.x.0/24, my local subnet is 10.0.y.0/24, and the conflicting route is 10.0.0.0/8. Without the later route, I can't access all hosts on the VPN without manually adding the route after connecting to the VPN:
