In episode 96 of Thinking Elixir, José Valim returns for part 4 in our 5 part series as we count down to the 10 year anniversary of the Elixir project we know and love! In Part 4, we talk through the Elixir releases of 1.10, 1.11, and 1.12. We go deeper on the philosophy of “explicit vs implicit” and how that informs many design decisions about the language. We learn about how Elixir and Erlang loggers were unified, how matching on map keys in guards enabled receives block enhancements, how common date sorting bugs were solved with Enum.sort improvements (that you should really listen to), the improvements to application config, how exceptions work in Erlang and Elixir and much more! A packed episode!

In this post, we explore three profiling tools you can use to find performance issues in Elixir — cprof, eprof, and fprof: https://blog.appsignal.com/2022/04/26/using-profiling-in-elixir-to-improve-performance.html

In November 2021, we decided to give the Spandex library a try after reading an interview with its author on the Datadog website. After a successful initial setup, we identified one main improvement that needed to be done, which was to be able to distinguish the different layers. Also, there were a few issues: a lack of links between traces and logs, incorrect Datadog statuses with HTTP errors, and trace losses in asynchronous tasks. In this article, we will describe how we fixed these issues using existing pull requests, reported issues, and articles written by Spandex maintainers. https://medium.com/wttj-tech/adding-traceability-to-elixir-applications-with-spandex-our-experience-1b97978146e2

If you are tired of calling recompile within the interactive elixir shell and want to have a similar experience as with phoenix, give lettuce a try!

I know it’s a mouthful, but hear me out:

I’ve been looking for an autocomplete field that worked for my purposes (lookup in the database, not in memory, and support multiselect and the ability to limit the number of items a field could support.

Since it couldn’t find it and being the dumb dev that i am, i obviously wrote my own.

Plausible Analytics is of course built with Elixir and I’ve wanted to poke it for a long time. I don’t do any analytics on my site though so this one is for you all out there that might be eyeing Google suspiciously or simply trying to obey the law.

In episode 95 of Thinking Elixir, we talk with Philip Sampaio to understand the Rustler Precompiled project he created and what problem it helps solve. The project helps lower the bar for using Rust libraries for NIFs in Elixir making it possible to see more libraries using Rustler in the future. He explains what prompted the work initially and how projects can benefit from it. We discuss what it means for internal company projects and especially for libraries. He explains how the project addresses the many architecture and platform combinations too. We end with learning about his sample CI project that shows us how to set up our own CI systems to use it.
