Some applications might require the same codebase to be tested with different sets of environment variables. This article proposes a simple way to do so.

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

Most web applications that manage data in a database perform at least some form of create, read, update or delete (CRUD) operations on stored records. Moreover, web applications also often expose those operations via a REST API. Most database tables - corresponding to the entities manged by the application - need their own CRUD controller and set of HTTP endpoints. Because of this, large applications can quickly become tedious to develop and maintain. However, the logic for each table is usually quite similar. Auto CRUD has been developed to reduce this workload.

An HDD can be configured to spin down after a certain time via the APM settings which can be managed by smartctl. Unfortunately, those settings do not persist after a reboot. This article presents a solution to the problem

My router needed to be replaced. However, instead of buying an off-the-shelf router, I decided to give pfSense a go and install it on a second-hand desktop computer.

Kong is a popular API gateway that can be used as a reverse proxy for clients to access back-end services. It can be run as a Docker container and, as such, can be deployed to Kubernetes. However, when doing so, requests might be severely impacted by unusually high latency. This can be solved by configuring the order in which Kong resolves DNS records.

With newer versions of Microk8s, its GitLab integration changes slightly. Here are the key differences

I recently replaced the RFID ring reader that I use to unlock my front door with an IoT fingerprint reader. An obvious advantage is that I risk losing my finger way less than a ring.

URL query parameters are a convenient way to store the state of a view so that the user can return to it using the back button after navigating away. This short article introduces a method to add parameters to the current URL.
