I’m not able to spend as much time looking after Ace as I would like and am looking for some help.

GO.Exchange is a cryptocurrency exchange which adopt Elixir in production. I’ve worked on this product for almost 2 years. I think would benefit to share what I’ve learnt in this journey.

I’ve been using alchemist and its built-in functions to work with mix tasks from Emacs: to execute a specific test, to execute tests in a file, to list all tasks etc. They work ok if you don’t work with umbrella apps. Umbrella project is an application split into multiple subprojects. alchemist uses custom Elixir app under the hood. This Elixir app is initialized only for a specific application. So it’s either initialized for a subproject or an umbrella project. Maybe there are customizable variables that allow you to work with umbrella projects and subprojects at the same time but I couldn’t find any.

I spend my days writing Elixir code and sometimes I want to execute a Mix task from the root directory for the whole project (for example, to run a credo check) and sometimes I want to execute a task from a subproject (for example, to fetch deps only for this subproject). mix.el allows you to do it. Also, it allows you to add additional parameters before executing a mix task.

In this episode of ElixirMix, we talk with David Bernheisel about the power in Ecto. Coming from ActiveRecord, Ecto and Changesets were a wonderful alternative! We cover David’s blog post where he shares tips and tricks for working with Changesets. We cover, Ecto.Multi, how to compose Changesets, “embedded” schemas, and much more!

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.

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

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.
