Patio Pizza and Talks at doloops

Let's enjoy the hopefully last nice days of summer/fall on the doloops rooftop patio! There will be talks and food and drinks. Talks Short Summary of ElixirConf US 2026 by Aaron Cruz Lessons from Optimizing Phoenix Integration Tests by Rodolfo Carvalho Phoenix integration tests provide important coverage for the mix phx.new command that scaffolds new projects and the multiple code generators that ship with the framework (mix phx.gen. tasks). The testing matrix is large, covering different Elixir/OTP versions and multiple flag combinations across distinct database targets: PostgreSQL, MySQL, MSSQL, and SQLite. Running them in CI meant waiting through long opaque runs with little visibility into what was actually taking time. Not anymore. In this talk, Rodolfo shares lessons from recently overhauling Phoenix's integration tests, making them faster, more reliable, and more observable. You will walk away with concrete techniques you can apply to your own projects to speed up slow test suites, fix CI bottlenecks, and understand your tests better. Speaker Bio Rodolfo Carvalho is the founder of [Praia Labs\, advising engineering organizations on system design\, performance\, and developer productivity. He is an active Phoenix Framework contributor\, upstreaming bug fixes and improvements from his work back to the community ([@rhcarvalho](https://github.com/rhcarvalho)). Good enough security by Roman Almeida After experiencing a security incident, I realized I had a blind spot for a particular kind of security risks. How I stopped caring about how I can deliver my next task in world-class quality and embraced the boring suck of processes (not the elixir kind). Speaker Bio Roman is an auto didactically trained developer, who thought he knew enough about tech at 22, studied economics, learned what price signals, incentives and optionality were, thus decided to go back to tech and tries to catch up ever since. Often tries to inject economic concepts into the world of software development, because he has not understood the sunk cost fallacy well enough. --- Thanks again to our host and food/drinks sponsor https://doloops.net, an Elixir/Erlang agency in the beautiful 5th district of Vienna.
