This post describes how I discovered that the load time for interactions in background tabs is 22x to 56x slower

In this post I rant a bit about bitwise operators and review common ones.

In this post, I try to reproduce the article "Let's build a Full-Text Search engine" to learn more about full-text search databases and Rust.

For a while now, Redux is working on improving its image with the development of Redux Toolkit. The old conception that redux was too verbose, hard to onboard, hard to learn, and unnecessary for most applications is in fact becoming something of the past. The Redux Toolkit is full of utilities to ease development providing simpler ways to set up a store, create reducers, and deal with immutable updates, allowing you to do more with less code. Some highlight features are:

• RTK Query
• Typescript support
• createSlice
• createAsyncThunk
• createEntityAdapter
• createListenerMiddleware

SRE is what you get when you treat operations as if it’s a software problem. This field originated at Google and spread into the broader software development industry, and other companies subsequently began to employ site reliability engineers. Organizations who have adopted the concept include Airbnb, Dropbox, IBM, LinkedIn, Netflix and Wikimedia.

Summary of what I was experiencing after one year in a master's program.

GitHub Actions was a great addition to GitHub. They streamline the development workflow by keeping all continuous integrations and deployment processes inside the project's repository instead of in an external tool.

The MVP of my second brain.

A write-up on how I imagine my second brain and early proposals on how to build it.

Formalizing to myself the building blocks of the memex.

Data is the cornerstone of many business models today, with this post I start a journey to own and analyze my data.

Does a philosophy of life matter? Stoicism was a philosophical school dedicated to teaching youngs Romans how to live well. Based on the intuition that our society is in a permanent state of decadence, I discuss how ancient philosophy approached the common problems of human living.

For some time I have been trying to become a runner. I think is badass and pretty, and I want that for myself. It doesn’t grow on me the idea of being super fit and run marathons, my goal is to run a 5k without feeling completely drained. I do my runs on a treadmill since I don’t live near a park and the city is dangerous. I also have no coach, besides the built-in programs on my treadmill and conversations with my brother which has a general interest in fitness.

In my quest to populate this blog with relevant content, I'm willing to share the most embarrassing and rookie mistakes I've made (multiple times) during my two-year master's program. My hope is to help some other rookie like me or entertain someone more experienced.

Cryptocurrency is awesome. At some point we all hear about that, the media is talking, our friends are talking and some important people agree that this is the future. So, in the beginning of this year I decided put myself into this and see if the future is really that awesome

This was the result of my scientific research, made in 2015 for the University of Pernambuco.

This week I was in face of a challenge. I had to build a simple desktop application that gives for the user a combinatorial analysis of a number sequence. With the timeline of one day. I ended up doing in Java, using Swing (Yeah, I know, not the best way to do it, but at the moment I just keep thinking simple is always better). Along the way, I find out an awesome platform for build desktop applications call Electron.
