Check out how I used Wireshark to help reduce the tedium of testing my Elixir-based serializers and parses for the Bitcoin peer-to-peer protocol:

Generating Test Fixtures with Wireshark

Just published first release of harnais_runner.

The package is based on the old code but is almost a complete rewrite.

All the old tests work. Tests are now run concurrently. Also a test can be compared with a “reference” test.

Lots of details and examples in the docs

New release of plymio_codi today incorporating support for plymio_vekil I published yesterday.

In this post I would share with you some experiences about how to develop a web application that can “simply” scale to a distributed system https://medium.com/@GPad/from-web-application-to-distributed-system-prologue-ee61ce2e992e

Just published the first cut of plymio_vekil.

A vekil is a collection (kv store) that associates proxies with forom.

Vekils implement the vekil protocol and forom implement their protocol.

The package include a couples of concrete vekils and four forom to illustrate. Lots of examples as always.

• Complete #{ with }.
• Show whether variable/module attribute usage is read or write.
• Find Usage for call definitions (functions and macros).
• Improved element descriptions, so you can tell alias vs defmodule vs decompiled defmodule with Go To Declaration lookup.
• Full Elixir 1.6 grammar change support.
• erl_abstract_code format Dbgi chunks are decompiled and translated to Elixir from the Erlang Abstract Code.
• Allow zero or more lines after struct name before {.
• Lazily create editor panels for BEAM Chunks Code, ExDc, and Dbgi tabs.
• Allow true: and false: keys in maps/keyword lists.

Distributed transactions are hard and expensive, if you wonder how to pragmatically handle them in a mid-size project— this article is for you. We will discuss how can we use Sagas pattern to run a distributed transaction from Elixir on examples that leverage Sage package. As a bonus, you will see how to use Sagas to organize your domain contexts.
