Notes from ElixirConf EU 2018 (part 3)

Continuing our series of posts describing the experience of joining this year’s edition of ElixirConf EU 2018, today we will talk about the tools around processing big amounts of data using GenStage and Flow.

Notes from ElixirConf EU 2018 (part 2)

As we mentioned in our previous post, some of us at SB attended ElixirConf EU 2018 in Warsaw, last April. We already covered some of the most interesting topics in the post and here’s another one that we think you may enjoy: it’s the summary of Georgina McFadyen’s talk on SOLID properties in functional languages and Elixir.

Thoughts and Notes from Women of Silicon Roundabout 2018

I have spent over two decades in management & the last 18 years in Tech and I have been privileged to work for some truly amazing companies and some at the other end of the scale as well. I could tell you some awful things that have happened to me in my working life and at the opposite end of the scale many amazing experiences and challenges that have shaped who I am.

Notes from ElixirConf EU 2018 (part 1)

Many of us in Simply Business have taken an interest in Elixir lately: it’s fun to use, it’s got a very solid foundation in Erlang and it could fit some of our use cases quite well.

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.

Block a specific gem version in your Gemfile in Bundler

If you ever want to exclude or block a specific version of a gem in Bundler, you can.

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:

1. Introduction To Zookeeper
2. Zookeeper Service Availability

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.

Introduction to Zookeeper

Zookeeper is an Apache project that was designed and implemented to help other developers build distributed applications. Many of the services that Zookeeper provides are a common set of services that all distributed applications require. Zookeeper implements them for you so that you don’t have to implement them yourself, letting you focus on your application rather than on distributed infrastructure components, like naming, configuration management, synchronization, group services e.t.c.

Note: This is the first story in our encounter with Zookeeper. Following story can be found here.

Loading Constants - Ruby VS Rails (Part 1)

Ruby is an Object Oriented Language with many unique characteristics that make it, not only a pleasure to work with, but really powerful too. If you have used constants in other languages you will be surprised how Ruby defines constants, and, actually, how Ruby loads them into memory. On top of that, Ruby on Rails takes it even further and uses a convention to allow constants to be loaded with minimum programmer’s hassle.

Loading Constants - Ruby VS Rails (Part 2)

This is the second part of a two-parts blog post about how Ruby and Ruby on Rails treats constants. On Part I, we have studied the way Ruby deals with constants. On this second part, we do the same for Ruby on Rails.
