The author tried a subscription service but found the dashboard to be cumbersome and lacking SSL for database connections. They also highlighted the need for technical knowledge to configure certain aspects, like Traefik tags. A major drawback was the absence of zero downtime deployments, causing pending requests to be killed during app updates. The author had expected a more user-friendly experience similar to Heroku or Vercel but was disappointed. Ultimately, they concluded that for deploying apps on their own VPS, they would prefer alternatives like Kamal or Dokku, which offer zero downtime deployments and additional features like certbot and proxy support.
Top 2 Comment Summary
The author highly recommends Coolify as a superior alternative to Heroku for hosting services, assuming zero downtime deploys are not essential. They have successfully hosted over 100 services for Hack Club on Coolify for three months and describe it as a reliable PHP application. The author suggests viewing Coolify as a user-friendly interface on top of Docker rather than a fully managed service. They note that other options like Dokku and Dokploy do not match Coolify’s maturity level based on their experience.

Total comment counts : 19
Summary
The article details Marca Tatem’s personal journey of recreating Daft Punk’s iconic track “Something About Us” using Ableton Live 12. Tatem describes how, after initially finding Ableton confusing, he discovered version 12 to be a refined tool that became his DAW of choice. He chose to recreate the track as a way to focus on music production techniques rather than songwriting, highlighting its significance within the French Touch movement, which is rooted in the cultural and musical landscape of late ’70s and ’80s France.
Tatem explores the blend of nostalgia and futurism in French Touch music, noting its influences from various cultural sources, including Japanese TV shows and the contributions of earlier electronic music pioneers. The article emphasizes that the unique warmth and texture found in original French Touch tracks are difficult to replicate with modern, high-resolution digital tools, which can strip away the imperfections that contribute to the music’s soul.
As he broke down the production process, Tatem opted for a warmer synth sound to emulate the original’s Wurlitzer electric piano, maintaining a focus on capturing the emotional essence of the piece rather than a strict replica. The article sets the stage for a detailed exploration of his production techniques and personal insights throughout the project.

10. The DDA Algorithm, explained interactively
Total comment counts : 3
Summary
The article discusses the author’s journey to understand the Digital Differential Analyzer (DDA) algorithm, which is used in voxel ray tracing for raycasting. While the author had previously implemented the algorithm by copying code, they found it challenging to grasp the underlying concepts. To clarify for themselves and others, the author presents a detailed explanation of the 2D DDA algorithm.
The DDA algorithm iterates through grid squares that a ray intersects, starting from a given ray origin and direction. The article explains how to derive the algorithm from scratch by defining the ray’s properties and plotting them on a grid. The author emphasizes the importance of understanding the geometric relationships between the ray and the grid lines, specifically how to determine the next grid square to fill based on the distances to the intersections with the grid lines.
Using visualization and basic geometric principles, such as the Pythagorean theorem, the author breaks down the calculations involved in determining these distances (lengthX and lengthY). The narrative progresses towards extending the understanding of these concepts to more complex scenarios, although the article ends abruptly before concluding the exploration of three-dimensional raycasting. Overall, the piece serves as an educational resource for those struggling to comprehend the DDA algorithm.
