I spend some time figuring out how to match Unicode chars in regexes, so I thought I would share: https://dev.to/lasseebert/til-unicode-chars-in-regex-1m9a

While at Tinfoil Security, I wrote and released a small open source lib to help unit test GraphQL query documents against an Absinthe API. It requires no Plug.Conns and removes lots of boilerplate using macros.

You can read more about it here:

Rafal Studnicki (@studzien) and I wrote about a better alternative to Process.sleep/1 for waiting on events in your tests! Make your test cases faster and more deterministic with busy waits: https://well-ironed.com/articles/the-virtue-of-busy-waiting/

There’s a really cool new BEAM language out there called Gleam. It’s super early days for the language, but wht it offers (strong type safety) I think is worth some experimentation for folks that are interested. Lucky enough for those of us currently using Elixir it’s trivially easy to use Gleam code in your Elixir applications, and in this post I show you how.

In this episode of ElixirMix, we talk with Lars Wikman and Emilio Nyaray about using Inky displays with NervesProject devices. We discuss cool things people do with e-ink displays, the satisfaction of hardware hacking, how they started the project, profiling Elixir code and much more!

Put together a small article about writing a super simple bridge between Workplace and Slack. It also uses Honeydew for no real reason. https://www.bobek.cz/blog/2019/workplace2slack-index/

TIL about Enum.map_reduce/3 and I wrote a little something about it :) https://dev.to/lasseebert/enum-mapreduce-3-3n55

LiveView makes it easy to solve some of the most common UI challenges with little to no front-end code. Keep reading to see how you can leverage LiveView’s live navigation tooling to build a sortable table UI. https://elixirschool.com/blog/sorting-a-table-with-live-view-live-links/

Although Elixir is a relatively new programming language, it is gaining popularity thanks to its concurrency, scalability and high fault tolerance.

Many market leaders recognized that potential and are choosing it for their new projects or replacing previous technologies with Elixir.

Broadway is Plataformatec’s fourth attempt at streamlining the retrieval and processing of data in Elixir. This article gives you a glimpse into that journey, provides a deeper understanding of the library, giving you everything you need to build your own Broadway application.

This video tutorial covers setting up Chrome Webdriver, configuring Wallaby to use it and it digs into some of Wallaby’s testing features:

• Scoping down find queries
• Walkthrough of Wallaby.Query source
• Building re-usable queries
• Putting a query into a module attribute

I started to work on this library about a year ago, it was put in production around December 2018. I figured it is time to publish it as a package.

Streams are neat when you are dealing with potentially infinite data sources. For instance, you query a database table and process returned rows as they arrive. Unfortunately, should a network hiccup happen, the entire stream would fail. Naively retrying the query could be expensive. RecoverableStream moves stream evaluation into a separate process, to isolate errors.

Wallaby is a library for running end-to-end integration tests in Elixir (probably Phoenix) apps. This screencast tutorial starts from a freshly installed Phoenix (v 1.4.9) app called “Wally”, installs the needed libraries, configures the app to use them and writes an integration test.

Take a deep-dive into Broadway as we build a simple data pipeline, and then improve its efficiency by using batchers.

Batching for Operations with Elixir and Broadway

In Elixir we deal with dependencies on a daily basis. For many developers, it’s not very clear what the difference is between the instructions we use for this task. Read Szymon’s article to learn more about this topic.
