Thankfully the author of Marked allowed for such an eventuality with the "Custom Processor" option.

To use this tick the box, put in your fully qualified path to pandoc and add your arguments and bob is your proverbial uncle. The quickest way to find out where pandoc is installed on your Mac is to type the following from the terminal.

Increase the Awesome

I’m sitting at my desk right now (9pm Sydney time), waiting for my 3am change window that I need to be onsite at the data centre for. Now I am supposed to be working on a presentation I am giving on Friday entitled “Automation, Orchestration, and SDN”. I’ve been given about 20 minutes to cover these topics, so I’m spending quite a bit of time trying to get the right mix of content without geeking out too far for the intended audience (C-levels, project managers and lead engineers).

While trying to get the mix just right, my mind keeps going back to a comment I made last week on the “APAC Virtualization Roundtable” podcast (Episode 74 “SDN & Virtualisation from a Network Engineers perspective”)…

“Increase the awesome, remove the mundane!”

While initially sounding facetious, this comment is kind of where my brain has been going of late when trying to work out where I should focus my energies. While I’m thinking of ways to apply this idea to many aspects of my life, I would like to present them in the context of the presentation I am about to give (and the same context to which Continue reading

DCCP – Datagram Congestion Control Protocol

How does the internet work - We know what is networking

DCCP transport layer protocol is used to control the datagram congestion. It provides an excellent procedure to stop the internet fall down, if it is caused by the congestion. In fact, this protocol is a brilliant competitor to be used as a substitute of UDP protocol. DCCP account DCCP congestion control trait by means of a reliable acknowledgments delivery (in form […]

Agile Writing – Week 1 – Getting Started with JIRA, GreenHopper and Markdown

I finished reading The Phoenix Project at the beginning of May and it has had a profound affect on my outlook towards work. Not only was this a great read, but while I was reading I kept getting ideas on how I could implement the three ways at work. This diary documents the transition to an Agile Writing workflow.

Why bother?

Before I start covering the how, I thought I would spend a little time on the why. Agile is something that is usually associated with Software Development and you might be thinking "What has this got to do with writing?". I write technical documentation for a living, but I've been a long time have-a-go programmer and I recently had the pleasure of working on a professional software project. One of the things that amazed me was how Agile mad them so much more efficient.

• Scope creep was eliminated through issue and requirements management
• Many application releases gets product in the customer's hands sooner
• Team maintains a constant velocity and is always striving to be more efficient
• Everything that can be automated, is.

It is actually quite easy to draw parallels between application development and writing technical documentation. A Continue reading

Consider an International Relocation

Over three years ago I saw an opportunity to take an assignment to my company HQ in Seattle. After debating this for some time with my wife we took the plunge and moved to the US. The question is, “was it worth it?”. For me the answer is an overwhelming ‘yes’.  I’m moving back to […]

Using Pandoc with Marked app

I recently changed from MultiMarkdown to Pandoc. But I still wanted to use Marked app to preview my work…

Why I switched from MultiMarkdown to Pandoc

For the last 6 months I've been using Markdown where I can. Since embarking on the path towards a more Agile approach to writing, it has been necessary to use Markdown more and more. This has led me towards using Pandoc Markdown rather than MultMarkdown as my dialect of choice and I hope to explain why.

Route Distinguishers and Route Targets

People new to MPLS VPN are often unclear on what functions route distinguishers and route targets serve, and the difference between the two. Let's see if we can clear up some of that confusion. If you could use a refresher on VRF fundamentals, I encourage you to first check out my earlier articles on the topic, Intro to VRF lite and Inter-VRF Routing with VRF Lite.

Route Distinguisher

As you know, VRFs allow IP address space to be reused among isolated routing domains. For example, assume you have to connect to three customer sites, all of which are using 192.168.0.0/24 as their local network. We can assign each customer its own VRF so that the overlapping networks are kept isolated from one another in their respective routing domains.

This works well, but we need a way to keep track of which 192.168.0.0/24 route belongs to which customer. This is where route distinguishers come in. As its name implies, a route distinguisher (RD) distinguishes one set of routes (one VRF) from another. It is a unique number prepended to each route within a VRF to identify it as belonging to that particular VRF or customer. Continue reading
