OpenProject in Kubernetes

OpenProject is an awesome project management application that can be installed on one's own server. This makes it ideal for users who want to keep control over their data. However, at the time of writing this article, OpenProject does not yet provide installation methods for Kubernetes so I decided to write my own manifest files.

IoT Kernel

Over the years, I have written firmwares for various IoT devices such as lights, locks or heaters. Those firmwares would generally handle a common set of basic functions like managing wifi connection, serving a configuration web interface over HTTP or exchange MQTT messages. However, having to implement and maintain those functions for each individual firmware quickly became tedious work. Consequently, I decided to write a library to handle all those basic functions. This library is used as a base for IoT device firmwares, on top of which device-specific logic can easily be added.

When used for the first time, the device will have no knowledge of what WiFi to connect to. Consequently, the smart outlet will generate its own, prefixed with the name <em>socket.</em>

TDD for an Express application

TDD has been proven to significantly reduce the amount of bugs in software releases. Moreover, with CI/CD systems, tests can be run automatically before the application deployment, preventing a faulty application to reach its end user. This guide goes through the steps required to set up a TDD workflow with an Express application.

File POSTer

Many web applications rely on the upload of files from client to server via a POST request. The content-type of this request is generally multipart/form-data. When developing the server-side of such application, being able to quickly test the upload feature can greatly increase productivity. So, I designed this simple web application that can POST a file to any URL.

Unlocking my apartment with my face

Unlocking my apartment with my face thumbnail
As part of a previous project, I installed an IoT lock on my front door, which allowed me to control it using my smartphone. However, having to take out my smartphone every time I want to unlock the door quickly becomes annoying. To improve on the situation, I installed an RFID reader on the lock, which I used in combination with an RFID ring which now serves as my key. To follow up on this trend of finding new ways to unlock my door, I decided to explore face recognition technologies.

Foreign models are quite in demand in Japan and as such it is not uncommon for foreigners living there to have a side activity in the modeling industry. I had the chance to meet the manager a <a href="https://azs-group.jp/" rel="noopener noreferrer nofollow">AZS entertainment</a> and was told that the agency was currently recruiting. So, since I am always looking for new life experiences, I decided to join.

The other day, I found myself putting on some weight. This rather surprised me as I thought I was having a healthy diet and exercised almost daily. To identify the root of the problem, I decided to start measuring my calorie intake as well as the macronutrients that constitute said intake.
