Part 2 of a this 3 part series examines how I created my Pelican blog and migrated my Wordpress content with me.
I've been blogging with Wordpress for the last 5 years on and off. It has some great features and is very easy to use, but it's not for me. This series of posts documents my transition from Wordpress to Pelican.
For the last 9 months, I've been silently working on a little pet project. It's finally ready to be released in to the wild and to be used by one and all for creating Python-based SDN Applications for the HP VAN SDN Controller.
The final installment in this three part series. This covers installing Dokku and publishing your pelican blog to you new Docker-powere mini-Heroku.
I get a lot of emails from people who read my blog asking my how I study. For most people they think I can tell them a magic formula, but the truth of the matter is that there isn’t one. You can also check out my Top 10 Study Tips You need to try all […]

There are a few things about Wordpress that have been bothering me lately
As with anything that relies on server-side scripting, there is performance hit when loading pages. I've been running my blog on a Linode 1024 VPS ($20 per month) and had found that I had to move from Apache to Nginx to get decent performance with Wordpress. Adding Caching to the equation with one of the many caching plugins available has also helped, but this is a rather complex solution. Another performance bottleneck is the database...
Wordpress requires a MySQL database in the back end. I am not a big MySQL fan and would prefer to run Postgres or MariaDB but this isn't officially supported in Wordpress right now. Not only is a performance bottleneck, but it is also another thing that needs to be backed up.
The Backup/Restore capabilities of Wordpress are decent, Continue reading

In Part 1 we saw we can mark prefixes in CEF with certain attributes that might give us interesting things to play with. In Part 2 we found we could track traffic patterns with the traffic_index tag. We will now turn our attention to the qos-group parameters. Let’s say we would like four categories of […]

Recently, one customer prospect asked the Contrail team to build a POC lab using only non-Juniper network gear. The team managed to find a cisco ASR 900 as a loaner device and we had to make that device work as a data-center gateway.
Typically we use the Juniper MX as a the data-center gateway in our clusters. When you use an MX, the system somehow feels dated. It does feel like a 10+ year old design, which it is. But it is incredibly solid and feature rich. So one ends up accepting that it feels a bit dated as a tradeoff to its “swiss army knife” powers.
The cisco ASR 900 belongs to the 1k family and runs IOS as a user space process on Linux. I’d not used IOS in 3 years. My first impression was: this artifact belongs to the Computer History Museum. In fact the CHM (which is a fantastic museum) has several pieces in exhibition that are more recent that 1984, the year IOS debuted.
And IOS (even the version 15 in this loaner box) is a history trip. You get to see a routing table that precedes classes internet addresses, the config still outputs “bgp Continue reading
Before we look at equalization and pre-emphasis, we should examine some fundamentals of waves and signals. A perfect square wave is a really useful way of representing a waveform in the time-domain, but it’s not the only way of looking at … Continue reading
