When using multiple GitLab accounts (e.g. private account and work account) on the same computer, you can’t use the same SSH key for both. This can become problematic when Git has to decide which key to use to communicate with the distant repository.
More …My blog is based on Jekyll, a static website generator. This means that the pages need to be generated before they’re deployed. Until recently, I used to build the content locally using a Jekyll Docker image, commit and push the generated content to my GitHub repo, SSH to my web server, and pull the changes from the repo.
The process was quite annoying, which is why I decided to set up a CI/CD (Continuous Integration and Delivery) pipeline, using GitLabCI.
More …My home server setup is composed of several Raspberry Pi, where I host different web applications (this blog, an RSS reader, some home IOT apps…). I’ve decided to setup a front gateway, that proxies the request to the right server:
Following my previous article, I’ll explain how to send the temperature data captured by a sensor connected to an ESP8266 to an MQTT server via WiFi, so it can be stored in an InfluxDB database, displayed as a graph, used on your home assistant installation,…
More …In this article, I’ll explain how to make a temperature sensor and display, using an ESP8266 board, a DS18B20 temperature sensor and an I2C LCD display.
The WiFi capabilities of the ESP8266 are not required in this project, but I intent to send the temperature values to an MQTT instance in a future version.
I’ve recently ordered and received a YubiKey Neo, which is a security key that can be used for two-factor authentication. This has motivated me to step up my security with stronger passwords.

A couple of weeks ago, I went to a Redis Meetup in Lille, presented by François Cerbelle. It motivated me to look a bit more into Redis.
Redis is an open-source in-memory key-value database, which supports different kinds of data structures, such as strings, lists, maps, sets, sorted sets…

More …Docker is the world’s leading software container platform. Developers use Docker to eliminate “works on my machine” problems when collaborating on code with co-workers. Operators use Docker to run and manage apps side-by-side in isolated containers to get better compute density. Enterprises use Docker to build agile software delivery pipelines to ship new features faster, more securely and with confidence for both Linux, Windows Server, and Linux-on-mainframe apps.
Kotlin is, as described on the official website, a
Statically typed programming language for modern multiplatform applications
Programiz has a great infographic that explains the interest of learning Kotlin.
