Dayron is a flexible library to interact with RESTful APIs and map resources to Elixir data structures. It works similar of Ecto.Repo but, instead of retrieving data from a database, it has underlying http clients to retrieve data from external HTTP servers.

Posted the fifth of a continuing series of articles on similarities and differences between Erlang and Elixir. This article covers exception handling in the two languages, demonstrating how closely they’re aligned.

The Merkle hash tree is an incredibly useful data structure used in a wide range of modern applications. Merkle trees are used in the IPFS file system, BitTorrent protocol, Git, Bitcoin, Ethereum, and a number of NoSQL systems like Apache Cassandra and Riak.

Today has been released Eikōn v0.0.2, an image parsing library that provides a read-only interface. PNG and GIF files are now supported !

You can find it on GitHub and Hex.

As the title really, thanks to the Erlang Solutions channel.

As a toy project to learn Elixir, I ported a Markov Chain written in Ruby to Elixir.

It generates funny tweets, like:

iex(1)> ExChain.create_filtered_sentence
{:ok, "I'm not a Food Social Network?", 0.4668037713169559, 4}
iex(2)> ExChain.create_filtered_sentence
{:ok, "I am in churros.", 0.30839889769910056, 2}

Suggestions are welcome.

The source code and instructions on how to use it are on github.com/eljojo/ex_chain

Posted the fourth of a continuing series of articles on similarities and differences between Erlang and Elixir. This article covers variable scoping in the two languages, comparing Elixir’s caret operator with Erlang’s single assignment, and exploring a few surprises in the scoping rules.

edib-tool 1.3.0 now includes a tiny but awesome tool which helps to minimize the image size even further: ExStripZip.

With mix-edib v0.7.0 you can utilize it pretty easily:

$ mix edib --strip

and your images will become up to 40 - 45 % smaller. (If you can squeeze out more, tell me about your success.)

Chris’ Phoenix Chat Example App (with Ecto stuff removed):

The lower barrier is around 10 MB (empty app without any hex dependencies) for stripped releases (unstripped: ~ 18 MB).

Furthermore there is also the option –zip, but you should use it only if you know that there are no NIFs in your app or its dependencies. (The savings of this compression are pretty small and not really worth the effort, as docker images are compressed anyway.)

Happy (tiny) image building!

New version supports “batching”: a batch is a metric aggregator designed to locally aggregate an numeric value and flush the aggregated value only once to the storage, as a single metric.

This is very useful when you have the need to write a high number of metrics in a very short amount of time. Doing so can have a negative impact on the speed of your code and can also cause network packet drops.

Full documentation is available online.

I often see people ask about the difference between Behaviours & Protocols. They exist in the same topic space of bringing polymorphic attributes to Elixir, but they do so by working with different parts of the language.

If you’d like to read more: Behaviours vs Protocols: what’s the difference anyway?
