Acing your CISSP exam, a guide

I recently passed my CISSP exam, after plucking up the courage following a long revision period. I decided not to attend any of the week-long courses as I learn better at my own pace and I would rather cover it part time alongside my work.

I graduated from Makers Academy in August 2018 and it’s now the start of February 2019 and I’ve been a junior engineer here for five months.

Notes from ElixirConf EU 2018 (part 1)

For a deep dive into the Elixir community and ecosystem, last April we packed our laptops and flew over to Warsaw, Poland, to attend ElixirConf EU 2018.

This is the first in a series of posts where we’ll share our notes from some of the most interesting talks at the conference.

Implementing Active/Standby Master Process

Zookeeper has been designed so that we can develop distributed applications easier. For example, we can use it to switch from a failing active process to a standby one, in an active/standby configuration. This is what this blog post is about. It demonstrates the ability to have a process switch from standby to active role, when another active process crashes.

This is the 3rd story on Zookeeper. The previous ones can be found here:

Zookeeper Service Availability

Zookeeper is a service that can be replicated so that one can have multiple servers running on different machines, essentially having a distributed Zookeeper service. This blog post explains, using a Ruby example, when Zookeeper service is available and when not.

This is the 2nd story on our encounter with Zookeeper. If you have not read the first one, you can read it here.
