2022-04-30 - Using the getent command
getentis not known to many users but it is very useful when you need to get information about users, groups, or other entities. The command can be used to get information about users, groups, or other entities for example without having to know where the information is stored.
The syntax of the
getentcommand is simple to use as it takes the name of the data source and possibly the name of the entry to retrieve.
2022-04-23 - Removing invalid state from Terraform
Terraform keeps a cache of state files in the
.terraformdirectory stored in Terraform Cloud so that it can be accessed by everyone in the organization. For existing resources Terraform has to import the state for a defined resource otherwise it will fail. Sometimes the state is invalid or an API will return an unexpected code and Terraform will fail to proceed.
The example below passed the error from the Cloudflare API via Terraform Cloud to the user but does not indicate the error. After verifying the state manually some resource records were already removed from the zone and triggered an
81044error. But the state was not removed and Terraform Cloud could not find the resource record to remove from the state database.
2021-12-23 - Migration to Cloudflare Pages
What started as a custom content management system quickly moved to WordPress to improve its maintainability and that solution served its purpose over the years. Having an easy web-based editor to maintain every is a good thing, but sadly also a bad thing. WordPress is a known target for attacks and you have to keep up to not be compromised, but this also means you have to keep up with how WordPress generates its pages otherwise the pages will not be shown correctly.
To reduce time and complexity, another solution was required as deploying WordPress with content every time wasn’t very effective. Most of the content was already in Markdown format to bypass certain limitations the next step came how to deploy them from GitHub. Static website generators like Jekyll, Sphinx, and Pelican came into the picture as they would remove the dependencies for installing code and a database.
2020-10-31 - Start using GitHub Dependabot
GitHub bought a service called Dependabot a while back and is now integrating this service as a GitHub Application into the ecosystem. This allows GitHub users to automatically do dependency management and get alerted when a security-related update has been found. For a while this service was in beta but it is now enabled for all public repositories and can be enabled for private repositories as well.
Let’s start simple and create file
.github/dependabot.ymlin the repository with the content below will tell Dependabot to scan all your GitHub workflows daily for GitHub Actions that are defined and have a newer release available. It will also create a pull request that can be merged when approved.

YouTube is one of the biggest video streaming sites on the Internet and you can find a video for basically everything on it. But in some cases, you can’t find a video anymore or it has been taken down or set to private for some reason. Having a local copy for personal or legal purposes can be useful, but by default YouTube only allows creators to export their content.
With the tool youtube-download, you can download the audio and/or video, and also subtitles in the languages you desire. The example below downloads the audio and video, and subtitles in English and Dutch. Also, it limits the frame size to 1920×1080 and stores everything in an MP4 container.
