ThinkingElixir 127: Ecto gets Lively in Livebook

Episode 127 of Thinking Elixir. We talked with Spawnfest competitors Filipe Cabaço & Joel Carlbark about their entry “Lively”. Lively was all about doing cool things with Ecto in Livebook. The project, later renamed to KinoEcto does 4 cool things around Ecto in Livebook. It builds Entity Relationship diagrams from the Ecto Schemas in your Elixir project. It can visualize the dense Postgres explain output and highlight a problem like when a full table scan is performed. It includes a ChangesetValidator SmartCell, and a QueryBuilder that uses NimbleParsec to parse a raw SQL query and do the initial work of turning that into an Ecto query. We talk about what the 48-hour competition was like, what they accomplished and what they plan to do next!

🏃‍♂️ 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.

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.
