Today we will continue exploring techniques for debugging and tracing Elixir code that are so important for running and understanding production systems. In the past, we have discussed: how to debug your application how to trace systems with Erlyberly how to use the observer to introspect applications. The examples above always connected to systems running locally. Given Elixirâs and the Erlang VM

When writing Elixir apps youâll typically find yourself building up state in a map. Typically these maps contain deep nesting. Updating anything deeply nested means you have to write something like: my_map = %{ foo: %{ bar: %{ baz: "my value" } } } new_bar_map = my_map |> Map.get(:foo) |> Map.get(:bar) |> Map.put(:baz, "new value") new_foo_map = my_map |> Map.get(:foo) |> Map.put(:bar, new_bar_map
Once youâre ready to deploy your Elixir application to multiple servers, youâll want to take advantage of the distributed features that the runtime offers. For example, if you are using Phoenix channels, youâll want broadcasts to be sent across the cluster. You can setup your deployment as a cluster in a few simple steps: Start by creating a new sys.config file in your project. Weâll conventionall

In this third in a trilogy of talks on autonomous robots, I present my latest re-design of a Society of Mind (i.e. multi-actor-based) implementation of Predictive Processing on Lego robots. I completely
First off, the md5 and sha1 cryptographic hash functions should only be used when security is not a requirement or when compatibility with legacy applications is needed. md5 was physically broken a very long time ago, and sha1 was theoretically broken back in 2005. When you need a hash for secure purposes, use a hash from the sha2 set (at least until sha3 starts appearing in libraries). Versioning

Short review of packages Recommend packages to try Deeper coverage of the recommended packages This is a short guide on getting started with Elixir and setting up a development environment using the Atom Editor. I chose Atom because it is OpenSource, free, cross-platform, highly hackable and pretty d
The Little Elixir & OTP Guidebook gets you started programming applications with Elixir and OTP. You begin with a quick overview of the Elixir language syntax, along with just enough functional programming to use it effectively. Then, you'll dive straight into OTP and learn how it helps you build scalable, fault-tolerant and distributed applications through several fun examples. about the technolo
Using Recursion In Elixir To Break Your OO Brain September 04, 2015 | I have to start out each post this way: I have no idea what I'm doing, but dammit am I having fun. In the fist few posts I ham-handedly threw some code against the wall to see what would ... stick? Anyway It worked, but I realized (as I did with Ruby, wonderfully) that there just has to be a better way. I don't want to diminish
