When you add the constraint of sensitive data or specific hardware requirements, this complexity can grow. Fortunately, tools like VSCode, Docker, and SSH are here to simplify our lives. In this post, we'll walk through setting up a development environment that leverages a virtual machine (VM) remotely, providing both security and flexibility.Tue, 03 Oct 2023 11:48:00 GMThttps://www.daangeijs.nl/posts/cell-counting-geopandas/https://www.daangeijs.nl/posts/cell-counting-geopandas/We all know that digital pathology demands efficient handling of large-scale images. However, I hadn't anticipated that the sheer volume of cell detections would significantly impact the performance of my cell density calculations within these images. This article combines the ease of WholeSlideData, shapely, rasterio, and geopandas to achieve this in a fast and simple way.Wed, 27 Sep 2023 11:48:00 GMThttps://www.daangeijs.nl/posts/umami-netlify/https://www.daangeijs.nl/posts/umami-netlify/Umami is a sleek, open-source analytics tool that provides an alternative to mainstream solutions like Google Analytics.

It all began when I realized that my [website](https://dekeukenvandael.nl) images weren't optimized as I had expected. I had been relying on the PaperMod and PaperModX themes in Hugo to handle image optimization. Everything seemed to be in place, but my images were still bulky and slow to load. The problem was evident, but the cause? Not so much.Wed, 09 Aug 2023 20:48:00 GMThttps://www.daangeijs.nl/posts/github-partials-shortcodes/https://www.daangeijs.nl/posts/github-partials-shortcodes/I code a lot, and GitHub is where I share my work.
