• How to track Detectron2 experiments in MLflow

    In this blog post, I’ll show you how to integrate MLflow into your ML lifecycle so that you can log artifacts, metrics, and parameters of your model trainings/experiments with Detectron2. As a result, you’ll be able to log training parameters (MODEL.WEIGHTS, OUTPUT_DIR, SOLVER.MAX_ITER, etc), training metrics (AP, duration, loss, etc.), and training artifacts (such as the model itself, training log file, sample images with inference, evaluation results, etc.) to MLflow.

  • Usage of Passport JWT Strategy for Authentication in Socket.IO

    Passport is an authentication middleware for Node.js that provides dozens of pluggable authentication mechanisms. You might already have implemented a Node.js backend with Express (and Passport). And now you’re wondering how you can protect the WebSocket communication between backend and frontend from unauthenticated access? Perhaps you don’t want to implement authentication twice, but want to reuse your existing Passport authentication via JSON Web Tokens (or any other strategy e.g. basic auth)? Then, this blog post is meant for you!

  • How to develop Flutter apps for Windows desktop (August 2020)

  • Run Nextcloud as Docker container with Docker Compose

    I’ve set up my private cloud using Nextcloud. Because I’m a huge fan of Docker, I decided to run Nextcloud as a Docker container. Luckily, there’s an official Docker image and they also provide examples on how to run Nextcloud with a standalone database using Docker Compose.

  • Transfer files using a USB cable to the reMarkable

    I decided to try out a so called digital notepad for university so that I can take notes on my lecture manuscripts. I ended up buying the reMarkable because it seemed to be the most complete concept (there are a lot of hacks available on Github to fix some of the reMarkable’s flaws).

  • How to create user interfaces in Unity for Google Daydream VR apps
