🏃♂️ Rewriting the strava summary in erl
Two weeks ago, I implemented a small script that gathers Strava stats and commits weekly to my GitHub profile using GitHub actions and elixir. I love elixir and it’s community, but I also love erlang, and I think we should love each other, so to bring everyone together, I decided to rewrite the strava summary in erlang: To know more visit: https://github.com/gilacost/gilacost/blob/master/ventures/STRAVA_SUMMARY_ERL.md
Elixir Distribution, ELI5
There are a few key points that help Elixir run in distribution. We will setup a cluster locally, and between two machines, and we will discover what the components are!
ThinkingElixir 126: Working at a Software Agency with the Wizards
Episode 126 of Thinking Elixir. As software developers, there are many different types of companies we can work at. We met up with the Elixir Wizards crew to learn more about working at a Software Agency like SmartLogic. We compare what this is like vs working at a product company. Of course, we take the opportunity to learn more about Sundi Myint and Owen Bickford, their journeys to Elixir and the work they are doing now. Sundi shares how becoming an Engineering Manager presented new growth opportunities and Owen goes deeper on the ETL system he’s creating to migrate an MSSQL DB to Postgres and how gets to play with Broadway in the process.
Erlang, Elixir and Friends Devroom @ FOSDEM 2023 (Call for Talks)
FOSDEM 2023 is finally going to be in-person again and we’re excited to announce that the Erlang, Elixir and Friends Devroom got accepted for next year’s edition. FOSDEM is a free conference dedicated to open-source software, one of the largest in the world, and it’s the perfect venue for us showcase the power of the BEAM and get even more people excited about it!
You can find all the information to submit a talk on the dedicated website.
Whether you’re submitting your talk proposal, or you’re just attending the event, we hope to see you in Bruxelles in February!
Adding PostgreSQL Active Connections to Ecto PSQL Extras
While working at Binary Noggin we ran into an issue with over provision database connections while using Oban.
Having active connections available in the Phoenix Live Dashboard helped us troubleshoot over allocating connections to the database. This has the added benefit of seeing all active connections not just our Phoenix application.
Securing Elixir/Phoenix Applications: 5 Tips to Get Started
There are a number of resources online related to Elixir and Phoenix security, however when it comes to securing your own project, determining where to begin is a difficult task. Here are five recommendations to get started improving the security of your application.
Rauversion: the opensource platform for music communities built in Elixir has released version 0.5.0
Hi, we have released Rauversion 0.5.0. It comes with the following:
- Events platform with a ticketing system that lets the community publish Free and Paid Events.
- Stripe integration that allows the community to link their stripe accounts to sell Paid events.
- Streaming event services integration with MUX, TWITCH, STREAM YARD, and ZOOM that allows the community to publish virtual events too!
- Track cover image generated by AI.
TIL: Regex with name bindings
In Elixir, regular expressions can extract a lot of useful information. Using Regex and named_captures/3 function, we can parse the input data based on the prepared regex.
Upgrading to Phoenix 1.7
To celebrate the first release of Phoenix 1.7, we’ll use Chris McCord’s upgrade guide to take an existing application to Phoenix 1.7.
Parser Combinators in Elixir: A Deeper Dive
In the second part of our two-part series, we’ll improve the parser combinator we’ve written. https://blog.appsignal.com/2022/11/15/parser-combinators-in-elixir-a-deeper-dive.html
ThinkingElixir 125: Elixir at the Royal Bank of Canada
Episode 125 of Thinking Elixir. While hearing how Elixir is being used in the Royal Bank of Canada’s Capital Markets, we learned a lot of extra things we didn’t expect! Thanos Vassilakis, head of R&D in the CM group, explained how middle managers talk about “scaling” to mean hiring staff with the goal of using all of their budgets. Not the kind of scaling we typically think about! Thanos identified the biggest problem limiting Elixir’s adoption at large financial institutions and it wasn’t what we expected. He also shared stories of how LiveView greatly out performed React when rendering hundreds of live updating financial charts and, after experimenting with it, the React devs fully adopted LiveView! Lots of great insights and stories in this one!
Elixir, OpenTelemetry, and the Infamous N+1
Alex Koutmos wrote an OpenTelemetry article for Phoenix projects by with an awesome demo repo that visualizes telemetry events with Grafana! It’s also a helpful guide on debugging performance problems like N+1 DB queries!

ThinkingElixir 124: Caching Things Anywhere with Nebulex
Episode 124 of Thinking Elixir. We wanted to go deeper on the caching library Nebulex, so we visited with the creator, Carlos Bolaños, to learn what prompted its creation. Nebulex takes a couple unique approaches to things. It supports a decorator pattern to indicate that a function should be cached without having to write the boilerplate code for reading and writing to the cache. Nebulex was inspired by Ecto, in that it supports multiple adapters to different backends like Redis, Cachex and even Horde! It also supports multiple caching strategies. It’s an interesting project that aims to solve common caching challenges in new ways and we enjoyed learning more about it.
