Developer Productivity I like to think that I am a productivity oriented person. If there is a faster or more efficient way of doing a task, I tend to incorporate that as part of my workflow. This can be small things like being able to jump directly to a certain application without having to do theCMD+Tabdance or being able to run a test without having to leave my editor. →

NFT Attribute Types: A rarity system (but with Maths) We want to pre-generate the metadata for a set of NFTs that will have several attributes, using mathematical distributions. This metadata has information on the traits of that specific NFT, in this case, each attribute type and the respective value. →

Giving TypingDNA API a spin - do we really have typing patterns? Some time ago, we found TypingDNA. It was a different approach to MFA (multi-factor authentication) or SCA (strong customer authentication), and so we got interested in giving it a try between ourselves and see how it works. →Diogo Viana · Development · August 2021
Developing a keyboard heatmap and customizing keys with Karabiner After joining Finiam, I started looking more into how I used my keyboard, and how I could become more efficient with it. So I decided to make a heatmap of my keystrokes using Elixir, and then create aliases or easier configurations for things that I identify as the most used with the help of Karabiner-Elements. →Diogo Viana · Development · June 2021
Ruby and Elixir - A brief comparison In the world of tech startups, time is an essential factor in the success of a company. Who can deliver the best work in the shortest amount of time gains a competitive edge over the competition. Not only that but in a world in constant evolution, the need to quickly change gears and pivot a business idea into another opportunity is of great importance. →Davide Silva · Development · May 2021

Predictable React authentication with the Context API Managing authentication in React might feel like a non-intuitive task for many, due to the difficulty of maintaining global state on React. In this blog post, I make a not-so-deep dive, but still deep enough to make an intro to React's Context API and ways of keeping the global auth state without 3rd party dependencies. →

Quantum computing in the financial world With Quantum Computing we are in a similar phase as Engineers and Computer Scientists were in the '40s or '50s, developing the first classical computers. I don't believe that quantum computers can fully replace our classical ones, but they surely will have a major role in our lives in the future, and we are just at the beginning. →Diogo Viana · Development · February 2021
Simulations with Elixir and the Actor Model A simulation of a game, weather, aerodynamic behavior, or any other action, has intrinsically the same goal - take a peek into the future and see how things will perform in real life. These simulations all require an extent of calculations and variables to take into account, but also a model that will elegantly run through them. Here we'll see how to use Elixir and the Actor Model in an example simulation. →Diogo Viana · Development · January 2021
Next.js and Airtable: a tale of empowering no-code tools Back in June, we received a request to help build a website for an academic non-profit organization (our friends at AAUM), in Braga, Portugal. They needed a website to help spread awareness of the MinhoCovid19 movement, a group of people trying to supply organizations in need (nursery homes, hospitals, etc) with protective materials built by volunteers. →Francisco Sousa · Development · December 2020
Refactoring or: How We Learned to Stop Worrying and Live with Chaos I will be completely transparent and start by saying that this blogpost itself has been rewritten a couple of times since its original idea. Given the topic we are going to discuss, it seems fitting that that happened. In the beginning of 2019, we took over a Rails project. On the surface, it looked like a typical Rails app with an integration to a payment service. The fun began when we started to take a closer look at the codebase. →Davide Silva · Development · December 2020
Reactive Rails applications with StimulusReflex A while ago I made a blog post about the modern web with just Rails (and a few other things). Today I'm going to explore another way of doing awesome things with Rails, in the spirit of the modern, reactive, and real-time, web. Let's explore StimulusReflex, an extension to the amazing library made by Basecamp, to make server-side reactive applications. →Francisco Sousa · Development · September 2020
Spicing up your Rails frontend experience Rails is great. You can still check DHH's 15-minute blog demo and just appreciate the combination of features and ease of use of the framework. Even though there are even easier ways to make a blog nowadays (cough cough Gatsby), Rails is still a rock-solid choice for crafting digital products. →Francisco Sousa · Development · August 2020
Let’s slim down on Javascript The ancient narrative of "Javascript bloat" is ever-present in the tech world. Web developers love Javascript, backend developers hate it and end-users usually don't give a damn about it as long as websites open fast, work as they should, and do not spy on them. Still, web pages have way too much Javascript, especially SPAs, that could be avoided with just a few tips. Let's see how. →Francisco Sousa · Development · July 2020
