Searching a category of files can be done in many ways. For example, a script that searches for a phrase in all GitHub Actions workflows on a computer could take only around a dozen lines of code in most languages. The best way overall I’ve found so far is with rg (ripgrep) in a bash script. It’s great because writing it doesn’t take long, the output formatting is useful, and it’s easy to adjust the output without changing the script....
Running a terminal command with Python usually looks like this: import subprocess subprocess.run(["git", "init"], check=True) Using check=True will make subprocess.run throw an exception if the command fails. If you don’t use check=True, you should probably check the return code yourself or the command could fail silently. You can catch errors like this: try: subprocess.run(["git", "init"], check=True) except subprocess.CalledProcessError as err: print(f"git init failed with return code {err.returncode}") To get any error messages that may be in stderr, you can use capture_output=True and text=True....
Whether a Docker container is healthy is not just about whether it’s running. A service could stop working properly without crashing. Docker can detect some of those kinds of invalid states when we define custom healthchecks. healthcheck in Docker Compose | Docker Docs HEALTHCHECK in Dockerfile | Docker Docs The way it works is you define a command for Docker to periodically run inside the container, and Docker uses that command’s exit code to determine whether the service is healthy....
I built something that makes my life a little easier, maybe: a tiny mental math quiz: Daily Math. I want to maintain a little bit of mental math skills with minimal effort, and I heard one of the best ways is to pick two random numbers and then add, subtract, multiply, and divide them. Daily Math takes care of coming up with two random numbers and checking whether your answers are correct....
PDFs can be generated programmatically in several ways. A common use case is converting a website to PDF, but some of the tools listed below work for other use cases too. Converting a website to PDF If you’re okay with text not being selectable or searchable, you could use html-to-image to turn the site into images, and then put the images into a new PDF with jsPDF. Use JPEGs so the resulting file isn’t too big....
Restic and Time Machine (TM) are backup programs that complement each other with their different strengths and weaknesses. I now use both: Restic for remote backups and Time Machine for most local backups. Platforms TM is only available for MacOS while Restic runs almost anywhere. Ease of use TM is much easier to use than Restic. When you connect an external drive to your computer, a popup will appear asking if you want to back up your computer to that drive....
Here’s a way to install Ansible that’s easier and more likely to work than the official instructions. Install uv if you haven’t already uv tool install ansible-core That’s it. You should now be able to use commands such as ansible, ansible-playbook, etc.
Immich is a self-hosted alternative to Google Photos. I’ve been running an instance for a few months now, and it’s great. Immich’s docs has a sample NGINX config, but there are a few changes you’ll probably want to make to it. Prevent indexing In the location / { ... } block, you should probably add a line that says add_header X-Robots-Tag "noindex, nofollow"; to prevent search engine crawlers from indexing your site....
On 2025-12-9, I tested the cross-compilation of the official Svelte template of Wails v2.11.0, a desktop app framework for Go, on my amd64 laptop running Ubuntu 24 with Go v1.25.5. Of course, the results may change in the future as Wails and Go are being improved. Go is known for making cross-compilation much easier than most other languages, and that is mostly still true when using frameworks like Wails. Creating executable files and/or installers for each of several platforms is sometimes as simple as listing those platforms in a command:...
A software project generator sets up the starting boilerplate for a project, filling in the new project’s name and other details in various places throughout the new files. Project generators make starting new projects much faster and lowers the barrier to quickly trying an idea. Their output can be much more reliable than that of LLMs. Like all tools, they are useful in some situations and less so in others....
