In Memoriam: Jon Portnoy (avenj)

Occasionally folks come into large IRC channels and ask some variant of “anybody alive?”. Sometimes I would reply, “No, we are all ghosts in the shell”.

Today, I logged onto IRC and found out that we did indeed have a ghost in our midst.

Jon “avenj” Portnoy is the type of dude on IRC who always says “hey” back no matter the time. Sometimes I thought the dude never slept. An avid Perl programmer¬†he made me see beauty in a language where I only saw gibberish. #otw will never be the same again but I hope the rest of us can keep the spirit of it alive.

In his memory, I have made a donation to The Perl Foundation. If you wish to do so as well, you can do so from here.

Rest in peace, friend.

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
