Inspired from the qz article: Samsung is accused of Volkswagening its TVs to oversell their energy efficiencyhttps://thatmlopsguy.github.io/posts/gitops-bridge/Sun, 16 Feb 2025 00:00:00 +0000https://thatmlopsguy.github.io/posts/gitops-bridge/As I reflect on my journey implementing the GitOps Bridge pattern, I’ve learned that it’s not just another technical solution, it’s a fundamental shift in how we manage our Kubernetes infrastructure. My experience began with a simple goal: to bridge the gap between creating Kubernetes clusters and managing them through GitOps. Traditional approaches to Kubernetes management often create a disconnect between two critical phases: the infrastructure provisioning, where you create and configure the Kubernetes clusters using an IaC tool like terraform, and the addons/application management, where you deploy the required applications within those clusters: monitoring, compliance and security addons.https://thatmlopsguy.github.io/posts/predictions/Sat, 04 Jan 2025 00:00:00 +0000https://thatmlopsguy.github.io/posts/predictions/As we navigate the complexities of our rapidly changing world, it’s more important than ever to engage in thoughtful discussions about what’s to come. Today, I’m excited to launch a new initiative called “Future Perspectives” – a indie web movement dedicated to publishing predictions and sparking meaningful conversations about the future. Building on the success of initiatives like the /about, /ideas, /now, and /uses pages, I propose introducing a /predictions page for each blogger.https://thatmlopsguy.github.io/notes/github-ssh/Sun, 29 Sep 2024 00:00:00 +0000https://thatmlopsguy.github.io/notes/github-ssh/Github stores public keys for each profile at https://github.com/<username>.keyshttps://thatmlopsguy.github.io/notes/energy-slaves/Sun, 08 Sep 2024 00:00:00 +0000https://thatmlopsguy.github.io/notes/energy-slaves/I reveal that if an average human being was placed on a rowing machine (or exercise bike, or treadmill…) for a year of 250 eight-hour shifts, the total amount of energy that the person could expend into the machine would be 500 megajoules. How much is 500 megajoules? It is roughly equivalent to the energy stored within 14 litres of gasoline (petrol).

In recent years, the DORA metrics, including “Time to Restore Service” or MTTR, have become a staple among software engineers aiming to measure the efficiency of software delivery processes. However, Courtney Nash challenged this conventional wisdom in her article “MTTR is a Misleading Metric—Now What?https://thatmlopsguy.github.io/notes/pytorch-docker/Tue, 13 Aug 2024 00:00:00 +0000https://thatmlopsguy.github.io/notes/pytorch-docker/You don’t need CUDA runtime because PyTorch includes all the necessary CUDA binaries, so you can save space by switching to a lighter base image.

This isn’t just another blog post; it’s a deeply personal exploration of how embracing constraints can lead to creativity and innovation. My fascination with the Small Web Movement began with a simple observation: the web is becoming too cluttered, too slow, and too inaccessible for many users.https://thatmlopsguy.github.io/posts/dockerignore/Mon, 01 Jul 2024 00:00:00 +0000https://thatmlopsguy.github.io/posts/dockerignore/When you’re using .dockerignore to ignore files within directories, it works a little differently than .gitignore. To ignore a file across all subdirectories, prefix the filename with **. For example, to ignore the file file.txt in all subdirectories, add the following to .dockerignore: **file.txt To ignore a specific file extension across all subdirectories, prefix the file extension with **/*. In this example, all files with the .txt extension will be ignored by Docker:https://thatmlopsguy.github.io/posts/devbox/Tue, 21 May 2024 00:00:00 +0000https://thatmlopsguy.github.io/posts/devbox/In the last years, I used a combination of homebrew and asdf to manage some developer tools (eg. terraform, hadolint, ShellCheck, …) Recently I discovered devbox, a wrapper around NixOS package manager.
