Firewatch and SUPERHOT: A Tale of Two Games

This past weekend I played two games: Firewatch and SUPERHOT. This post is not intended to be a review of the two games but a look at the polar differences between the two and why one gets a lot of flack for its perceived lack of content and why the other is praised for its mechanical purity.

Now you might ask, “Sadiq, why does this matter? These are two entirely separate games in two entirely different genres!”. To that I answer:

  1. Humour me, I need to flex my writing muscles.
  2. Do the words “value proposition” sound important to you? If so, you are in for a treat.
  3. The voices in my head say interesting things sometimes and I would like to write this down.

Let us jump in shall we?

An overview of OS support for IPv6 resolver distribution methods

In this post I will be going over the various levels of support for IPv6 resolver distribution for popular operating systems. Focus on desktop and mobile versions of OSes as those are the ones where we are usually automatically distributing resolver information. Dual stack is implied but IPv6 only functionality can be gleaned from said information as well.

CCIE Lab Diary – EIGRP Lab

Overview/Goals

Implement EIGRP in a 9 router network with frame relay as the underlying L2 encapsulation to demonstrate protocol behaviours in a NBMA environment. Also involves tweaking of various parameters using summarization, redistribution, various stub types, distribute lists etc.

Technologies involved:

  • Serial interfaces
  • Ethernet interfaces
  • Frame Relay
  • EIGRP

Logical topology

Pitfalls/Things to watch out for

  • Frame Relay PVC issues
  • EIGRP timers on “slow” links, might want to tune them

CCIE Lab Diary – Layer 2 Lab

This is going to be a series of posts regarding the labs from the CCIE Routing and Switching class at UOIT.

I feel like these labs are complex enough for such posts to be interesting.

Overview/Goals

As the title of the post suggest this is a lab that incorporates various L2 technologies to implement.

Technologies involved:

  • Ethernet interfaces
  • Serial interfaces
  • VLANs
  • STP
  • LAGG (EtherChannel)
  • PPP with CHAP/PAP authentication
  • Frame Relay (ugh.)

Logical topology

Pitfalls/Things to watch out for

  • The lab requires you to configure VLAN pruning on trunk links appropriately. Make sure to take a look at both the physical and logical topology to figure that out. Do this right the first time, you don’t want to backtrack later to fix issues with that later.
  • Frame relay is just as annoying as it was during the CCNA labs. Lack of practice with it does not help. Not all the DLCIs shown in the logical topology actually need to be used.
