Codecon 2021

Last week happened Codecon 2021 first edition, which was my debut as co-organizer.

Codecon is a tech event made for developers featuring tech talks, workshops, coding marathon, puzzles, prizes and lots of community interactions.

My role in this edition was mainly developing and taking care of our gamification Discord bot. While it's still not open source, it's heavily based on my other Discord bot Corvo Astral.

To keep the tradition of reporting what has been presented on the tech events I participate, here's what I have summarized.


🎯 Introducing properties tests on C# with FSCheck

By Arthur Fücher / Watch it here (portuguese)

Introducing properties tests on C# with FSCheck

In this talk, Arthur showed us the concept of a different test type: the property one. Compared to unit and integration tests, here we're validating if a given property from the input and output of a method is being satisfied. For example in a Sum function, we check if its commutative property (x + y = y + x) and identity property (x + 0 = x) are being respected with several auto-generated inputs.


🍝 Unspaghetting code: a refactor case

By Camila Campos / Watch it here (portuguese)

Unspaghetting code: a refactor case

Camila talked about a refactor project that she and her team had to do in a Credit Score application and how they managed to "tidy up the house" by aligning their goals with managers and stakeholders and drawing the flux of the application. It's clear that their approach resulted in a big relief and motivation to the team and a faster result delivery.


🌌 Galaxies TDD, how to finally understand and apply the tests universe

By Ana Neri / Watch it here (portuguese)

Galaxies TDD, how to finally understand and apply the tests universe

By presenting the concepts of the Test Driven Development using Star Wars theme, Ana elaborated how to achieve a resilient software with good quality. She also brought the most common mistakes we can make when applying TDD and their solutions.


🔭 From Callback to Observable with RXJS

By Fernando Daciuk / Watch it here (portuguese)

From Callback to Observable with RXJS

With a brief presentation and lots of live coding, Daciuk explained what Callbacks are, their evolution into Promises (kinda) and how we can use Observables in the practice.


👾 Adversary Attacks in Machine Learning

by Flavio Clesio / Watch it here (portuguese)

Adversary Attacks in Machine Learning

Flavio showed us several examples of how a Machine Learning application can be exploited by external agents, such as model poisoning or by internal failures, like unexpected distribution changes.


📈 Clojure is a Java better than Java

By Ana Bastos / Watch it here (portuguese)

Clojure is a Java better than Java

With details and examples, Ana presented Clojure as a programming language that runs on the Java Virtual Machine and being a Lisp derivative. She also pin-pointed its advantages, such as being an easy to learn language with simple syntax, have less code written to do the same as other languages would and all the good stuff that comes with a functional programming language.


⚔️ Kotlin vs Go: The coroutines war

By Alex Rios / Watch it here (portuguese)

Kotlin vs Go: The coroutines war

Alex made clear the difference between Threads and Coroutines and how Go and Kotlin implemented them in their languages. He also showed examples and talked about how useful is to apply the Structured Concurrency when using these features.


🔋 Internet of Things? IOT? What is it?

By Monica Craveiro / Watch it here (portuguese)

Internet's Things? IOT? What is it?

In a very didactic way, Monica explained what is IoT and its applications. She also brought subjects related to its architecture, such as sensors, dev kits, devices, legal aspects, connectivity, cloud and platforms.

Devs Cansados Podcast live recording

We also had a podcast live recording where "tired devs" talked about the programming industry and the devs everyday life.


Workshops

CodeCon21 also had several workshops for affordable prices and with a "buy one and gift or donate another" system.

  • Elixir Introduction (Adolfo Neto)
  • From Relational Modeling to Dimensional Modeling: assembling a DW example (Caroline Dantas)
  • Docker & Docker Compose - A class for starters (Leoni Mella)
  • Software Architecture Foundations (Pedro Castilho)
  • React Foundations (Juliana Gaioso)
  • Laravel + VueJS + Inertial - Develop SPAs without APIs (Thiago Victorino)

Gamification

And the most interactive feature we had was the gamification system distributed into several activies:

Conclusion

CodeCon is certainly the most dynamic and interactive web event I've ever witnessed and I've had a blast helping to organize it. The gamification bot I've coded myself worked better than I thought and this year I want to make it opensource so more communities can make use of.

I want to thanks all the people that have contributed with talks and workshop, PachiCodes for being our host and everyone who participated in the event.

A big thanks for the people who made this event happen: Gabriel Nunes, Galeno de Melo, Eduarda Cristina, Kaio Felipe and Alan Fachini.

We're probably going to have a second edition for this year, so stay tuned!
