Meetings are where I spend a lot of my time, they’re also one of the things that burn more cash and fatigue people in companies. Yet we repeat habits we know are destructive. This issue is dedicated to exploring ways we can make them better. As always, thanks a lot to everyone who shared the previous issues 🤗. If you’re feeling generous (and a little smarter) by the end of this, share it on Twitter and LinkedIn, and let’s help more people stop burning cash and, worse, time in meetings!

We talk a lot about quality, we rarely stop to explain what we mean. Quality is intrinsically connected with agility, so building effective, agile teams comes from being able to build quality incrementally. Knowing how to measure it is an important step in that way.

What’s Software Quality, after all?

When we’re building our product, we’re passionate about enabling users to do more, empowering them. This passion leads to the creation of more and more ways the users can use our products to better accomplish their goals.

React is improving fast and new versions pack a lot of different cool features built into the library. One of the coolest is the set of tooling around Memoization. In this post, we’ll learn a few tips and tricks on the subject, things I’ve used in production, and helped me speed up heavy renders.

Why it matters

Memoizing is a well-known concept in computer programming, aiming to speed up programs by caching results of expensive function calls and re-using those cached results to avoid repeating those expensive operations:

Like José M. Perez said beautifully in his article Fostering a Web Performance Culture:

Web Performance is not only about understanding what makes a site fast. It’s about creating awareness amongst both developers and non-developers. Performance is a feature and needs to be prioritized as such.

Mainly to get non-developers to buy-in, we need to size how much improving performance impacts business metrics and precisely to what…


Make it a habit to measure your performance. There may be a lot of easy but impactful fixes that you need to do;

A highway because, you know, like, fast things and such

At QuintoAndar we have been working hard on building our Single Page Application, Progressive Web App as a way to improve the experience of our users. As a part of this process, one of the main concerns was to have our web application feel native, providing a smooth and fast 🚀 experience. If you ever built a large javascript application, then you already know how much of a challenge this is.

During that process, we learned a lot about how to maintain good productivity while avoiding most pitfalls that can deteriorate performance. …
