Food manager
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.
Force IE to use its latest version
Depending on the settings, Internet Explorer can decide to render webpages using a lower version, which can result in compatibility issues.
GPS tracker
When I was in the army, we would often have exercises where we need to setup some equipment in the field and establish a security perimeter around to prevent access from unauthorized personnel. During those exercises, the sergeants and lieutenants would sometimes disguise themselves as enemies and try to access the equipment to see how successful we would be at stopping them. I didn't like the idea of staying alert for long periods of time and instead wanted to receive some kind of warning whenever a superior would be arriving in our vicinity so I designed a GPS tracker that I intended to put on his car.
General purpose IoT button
Over the years, I have built multiple IoT devices ranging from AC controllers to ceiling lights. Usually, I would control those devices using my smartphone or computer but sometimes a physical button can be more convenient. Thus, I designed this simple IoT button which publishes MQTT messages when pressed.
Generating certificates for an Aruba Instant AP using pfSense
Aruba IAP can use custom certificates when serving the Web UI over HTTPS. Those certificates can be generated, among others, using pfSense. This can be useful when trying to get rid of browser warnings regarding untrusted HTTPS connections
Generic Kubernetes manifest for web application deployment
Deployment name, container registry and service port are externalized, making this manifest general-purpose
Getting Python's requests library to use a local DNS (Core-DNS, Docker-compose, etc.) while behind a proxy
When using Python's requests library, the requests are send through the proxy set as environment variables. Consequently, if the DNS to be used comes before said proxy, the host might not be resolved. This typically happens when resolving a host in Kubernetes using Core-DNS. If the request first leaves the Kubernetes cluster to reach the proxy, then the DNS server becomes unreachable, making the request fail.
Git store credentials
Having to enter one's credentials for every push to a remote can be annoying. Here is to have git save those credentials for future uses.
GitLab CI
GitLab CI is a feature of GitLab that allows users to have actions triggered upon pushing a repository to it's remote. For example, it can be used to execute all tests defined in the code, containerize the application and deploy it. A popular alternative to GitLab CI is Jenkins.
GitLab CI Microk8s integration
GitLab provides Kubernetes integration out of the box, which means that GitLab CI/CD Pipelines can be used to deploy applications in Kubernetes easily. This guide presents how to integrate a Kubernetes cluster in a GitLab Project and follows Gitlab documentation. For this particular case, the cluster will be that of a Microk8s Kubernetes distribution.
