ALEx makes it easy to write AI Agents for Atari 2600 games in Elixir using the ALE Framework.

I am converting a Rails app to Phoenix and have to convert a number of CSV reports, so I searched but did not find an easy to use library to generate CSV files. I wanted something a bit like Ecto.Schema , so CsvGenerate was born, https://hex.pm/packages/csv_generator

During this difficult times of Corona Pandemic, I am helping my local community of drivers, daily wagers, homemaids who are financially affected by loss of jobs. Their lives are threatened with no financial means to meet out their basic needs of their families.

To help them, 100% sales of my books https://shankardevy.com/phoenix-book/ will go towards helping people financially affected by COVID until further notice.

Part 6 of the Simple Phoenix LiveView App series.

In this episode, we’ll start converting the new users page and form into live views. In the process, we’ll get to see LiveView and Phoenix form validations in action.

Part 5 of the Simple Phoenix LiveView App series.

In this episode, we’ll add some PubSub functions to the Accounts Context for user-related LiveViews. Then we’ll write a LiveView for the users index page.

A few thoughts and opinions about uses for GenServers in web development. Summary: use them for simple recurring background jobs and sparingly otherwise!

Part 5 of the Simple Phoenix LiveView App series.

This episode we’ll use generators to scaffold the following for users, podcast episodes and comments:

• contexts
• schemas
• migrations
• controllers
• views
• templates

We’ll also set up a few basic validations.

Epidemic Mitigation in Elixir using a Genetic Algorithm to eliminate most impactful connections in a graph.

LiveView click event and offsetX, offsetY coordinates

I made a tiny tiny contribution to the Phoenix LiveView project (just two lines of code available from release 0.5.0), which adds offsetX and offsetY coordinates to the click event metadata.

These coordinates are useful to know exactly where the click happened inside the element. In this article I show how to use phx-click and offsetX,Y coordinates, letting users interact with SVG elements

Thanks to the lockdown I’m working in my free time on a project to have a curated chronology of the official announcement related with the COVID-19 on Ecuador.

The repository lives here: https://github.com/mijailr/alertas.ec

The tech stack is:

• Elixir
• GraphQL
• Typescript
• React
• Docker
• Heroku
• GitHub Actions

You can see the prod environment on Alertas.EC

Any feedback, suggestions or help, is welcome.

In today’s post, we’ll learn what gRPC is, when you should reach for such a tool, and some of the pros and cons of using it.

Lately, I’ve been thinking about the idea of creating a web app for storing and visualizing my cycle rides.

In this blog post, I would like to present my findings on how to store and visualize GPX tracks using Elixir/Phoenix, PostgreSQL and a little bit of JavaScript. The plan is to parse the GPX file and extract track data. Save it in PostgreSQL as a geometry type, which comes with PostGIS. Finally, visualize track using an interactive web map.

GenRMQ is a set of behaviours meant to be used to create RabbitMQ consumers and publishers.

Changelog:

• Deprecate uri config attribute and introduce connection option for Consumer and Publisher

• Handle redeclaration errors from the broker

This is an app I built last weekend while stuck indoors. It’s called The Bell; a way to stay connected when you’re apart.

For my fellow mixologists, it’s a Phoenix app with channels, hosted on Gigalixir. 💜 Elixir!

Do you work on Elixir projects that need to handle file uploads from users?

Waffle is a flexible library, developed by one of our engineers — Boris Kuznetsov — which does the hard work of handling file uploads for you, whilst providing easy integration with storage services such as Amazon S3, Google Cloud Storage, Azure, RackSpace Cloud, as well as image manipulation tools such as ImageMagick, so that uploaded files can be optimised on-the-fly!

Waffle grew out of a fork of a now-unsupported library, to which we’ve added complete documentation, fixed outstanding issues, merged open pull requests, added integrations with other parts of the Elixir ecosystem (in particular Phoenix and Ecto). We’ve also working on new features, such as file validation based upon content rather than the type supplied by the browser.

This release of Waffle is v1.0.0. If you’ve previously used Arc, you’ll find the transition to Waffle very straightforward, although note that the dependencies have been upgraded, and Poison has been removed in favour of Jason.
