Akitando News (codename The M.Akita Chronicles)

I am Fabio Akita, known YouTuber at @Akitando channel. I published videos from the end of 2018 until the beginning of 2024. I also participated in many important Brazilian podcasts such as Flow and Inteligencia LTDA throughout 2024 and 2025. Prior to that I was the former organizer of Rubyconf Brasil from 2008 until 2016. I write at the blog akitaonrails.com since april of 2006 until now. I am also the co-founder of a boutique consultancy in Brazil especialized in team augmentation for USA dev teams called CodeMiner 42.

I am also very active in X.com as @akitaonrails.

Now, I want to try a new project: a Newsletter. This needs to be divided into multiple sub-projects here.

Setup HashiCorp Vault on docker

Vault secures, stores, and tightly controls access to tokens, passwords, certificates, API keys, and other secrets in modern computing. Vault is primarily used in production environments to manage secrets. Vault is a complex system that has many different pieces. There is a clear separation of components that are inside or outside of the security barrier. Only the storage backend and the HTTP API are outside, all other components are inside the barrier.

Figure 1: Architecture of Vault and Spring App (Click to enlarge)

The storage backend is untrusted and is used to durably store encrypted data. When the Vault server is started, it must be provided with a storage backend so that data is available across restarts. The HTTP API similarly must be started by the Vault server on start so that clients can interact with it.

Encrypted dual boot setup with Pop!_OS and Windows 10

How to guide, using LUKS and Bitlocker on Dell XPS 17 9700

This guide is for those who want to use their XPS 17 in dual boot with their (preinstalled) Windows 10 and a new Pop!_OS installation, without giving up Bitlocker Encryption in Windows nor LUKS encryption in Linux.

The only guides that I could find were for Ubuntu, which it should be identical to, but I found the ommission of a few steps to resolve issues that I encountered in my first install attempt. Hoping to save you some trouble, I am sharing the steps that worked for me, linking the original guides that I found useful.

1. Preparation

• 1.1 Of course: Backup all your data! You always do this when people tell you to, right? Maybe this time better be safe than sorry.
• 1.2 Safely note your Bitlocker recovery key somewhere off your XPS. Where to find it
