We’d like to invite you to the 15th Poznań Elixir Meetup!

The plan is to have two interesting presentations but also have some time to grab a beer and pizza, meet people and talk about Elixir programming language.

Schedule:

Yevhenii Kurtov - A correlation between code quality and job satisfaction Adrian Borowski - Fun with Nerves. How to build your own smart home system without sweat and tears Networking & pizza

A full video is now up discussing the stack I would use. I honestly only care about the intro though. Who doesn’t want to be competent, save time and purify their soul? https://youtu.be/Y1wPRAHTE_E

Absinthe and Phoenix are amazing frameworks, but what happens when our requests take a bit too long to encode? In this article we explore how we can use caching and plugs to short-circuit JSON re-encoding of large structures and speed up our responses.

Episode 113 of Thinking Elixir. Livebook Desktop is a recent project that makes it much easier for people to start using Elixir and Livebook. Wojtek Mach joins us to explain what Livebook Desktop is and how it works. We learn who the project is for and the problems it helps solve. We ask if this approach makes sense for other projects and if so, how to get started. Wojtek also shares some cool things in the works that make it possible to load our own Phoenix project into a Livebook!

At SwayDM, we use the fantastic Knock platform for notifications, and Sentry for error reporting. With a bit of custom configuration, you can have them work together nicely. https://milwaukeemaven.blogspot.com/2022/08/fingerprinting-knock-errors-for-sentry.html

In 1996 Google co-founder Larry Page posted in comp.lang.java, Q: Setting User-Agent Field?. 26 years later, you may still need to set the User-Agent in your project. Here are four examples from the Elixir HTTP clients Finch, HTTPoison, Req, and Tesla.

Episode 112 of Thinking Elixir. Google Chrome extension that displays a LiveView and integrates with a web page like Gmail? Steve Bussey shares how he did just that! We learn how it worked, why he did it, the benefits he sees, and how this differs from the conventional approach. He explains the small JS shim used, recommends a library to help when integrating with Gmail and he explains how the user experience is great, particularly when rolling out new versions! Steve goes further to talk about Chrome’s new v3 extension API and targeting multiple browsers.

Code coverage is an effective means to assist software engineers in verifying code quality. The runtime environment’s ability to collect code coverage fully combines black and white box testing capabilities and greatly increases engineers’ confidence in software quality. This article introduces a solution for code coverage collection in the Elixir runtime environment, and provides an in-depth insight into its internal principles.

We just launched mirego/elixir-security-advisories, a new repository to replace the community-maintained (and now archived) dependabot/elixir-security-advisories.

The new repository data is completely automated and sourced from GitHub Advisory Database and is perfect for public usage (while GitHub API requires authentication to fetch security advisories).

In most programming languages we often deal with instructions responsible for handling dependencies. Elixir is no different.

In Elixir, dependency is nothing more than compiled module which for some reason you want to use in another module. There are a couple of instructions that we use in Elixir to either make it easier or possible to interact with modules.

In this blog post Szymon Soppa explains and presents use case examples of four of them:

alias, require, import, use.

This is a thorough guide for SQL experts and newbies alike, so let’s summarize what we’ll talk about in this article:

We’ll explain what the purpose and characteristics of transactions are Then, we’ll outline how to approach them in Elixir, using “the Ecto way” Finally, we’ll get to explain how it feels superior to different ORMs
