  • The unintuitive latency over throughput problem | tkowal
    2017-05-18 wordpress.com

    Blog

    Since 15.01.2015, I am teaching a course about Elixir programming language. It is created by José Valim, who is Rails Core Team Member. He knew, that Erlang virtual machine easily solves problems, that are hard to solve in Ruby, mainly concurrency. During my first presentation, I had couple of slides, that showed, what is so great about Erlang VM, that José picked it for implementing the Ruby successor.   https://tkowal.wordpress.com/2015/01/27/the-unintuitive-latency-over-throu ...

  • Intro to Elixir for non Ruby programmers – A PHP and Javascript perspective
    2017-05-11 ryanwinchester.ca

    Blog

    I come from the land of PHP and Javascript, with very little Ruby experience. I have seen quite a few posts around the interwebs introducing Elixir from a Rubyist’s perspective but I haven’t really seen any from a perspective I can relate to. The syntax of Elixir is kind of foreign to most people outside of Ruby-land, so I hope to help push people a little bit over the initial hump with some examples using PHP and Javascript (ES2015) along with the Elixir examples. My goal with this post ...

  • Event Sourcing in Elixir
    2017-05-11 zilverline.com

    Blog

    In this post we will explore how we can use some of Elixir’s more interesting features to implement event sourcing. OTP is the star of this show, enabling us to do some very nice tricks that would be practically impossible with Ruby. OTP stands for Open Telecom Platform, and is Erlang’s answer to the problem of concurrency. OTP relies on immutability of data to provide some very nice abstractions that make working with it very easy. https://tech.zilverline.com/2017/04/07/elixir_event_sour ...

  • Lasp: a little further down the Erlang rabbithole – This is not a Monad tutorial
    2017-05-10 notamonadtutorial.com

    Blog

    A few years ago I found Lasp: “a suite of libraries aimed at providing a comprehensive programming system for planetary scale Elixir and Erlang applications”. At this point it should come as no surprise for you to learn that here at Not a Monad Tutorial we are are interested in distributed systems and Erlang. After playing a little bit with Lasp I watched a few talks by its creator: Christopher Meiklejohn. After watching his talk “Distributed, Eventually Consistent Computations” I decide ...

  • Phoenix, Ecto and time zones | Michał Łusiak
    2017-05-09 mlusiak.com

    Blog

    In the previous episode, I calculated the distance of flight. I will use it later for gathering statistics. Another metric, I would like to have is a time of flight. Usually, flight departure and arrival times are presented in local time. So it gets a bit tricky to get the time length when the journey spans across few time zones.   https://mlusiak.com/2017/05/07/phoenix-ecto-and-time-zones/ ...

  • Using an Elixir Umbrella | 8th Light
    2017-05-09 8thlight.com

    Blog

    In Elixir, an application is a component implementing some specific functionality. It is a unit that can be run independently, thus started and stopped. It can also be reused by other applications, much like a library. https://8thlight.com/blog/georgina-mcfadyen/2017/05/01/elixir-umbrella-projects.html ...

  • Ask HN: Looking for the best Phoenix/Elixir/Erlang Tutorials | Hacker News
    2017-05-09 ycombinator.com

    Blog

    Hi. I am just starting out in web development and am looking for any tutorials on Phoenix/Elixir/Erlang. I am not familiar enough in the language to a) know if a tutorial will actually compile (I have had issues with this in the past) and b) how recent the tutorial needs to be given the latest updates to the language builds. Any and all tutorials where I can build an actual thing would be very useful to me as would resources such as "this in x minutes" that gives snippets of code that do someth ...

  • Lists, Maps and Commas – Erlang Battleground – Medium
    2017-05-08 medium.com

    Blog

    How Many Maps? Quick question: how many maps do we have in the following list? [#{a => 1}, #{b => 2} #{c => 3}]. 1 2 3 That doesn’t even compile! People following the erlang-questions mailing list might know already, but the correct answer is not 3, nor a compile error. It’s 2. Why not 3? Well, there is a missing comma in the second row. But why does it compile, then? Because what’s written there is a perfectly valid expression, of course. ...
