One of the big project from last year for me was to create a nice small homelab. On my previous projects, namely AuroraWatch and my personal document manager, everything was running inside my tiny NAS memory with my even tinier NAS CPU. It was fine for a basic project like aurorawatch that only fetches a website and does some text extraction and analysis. But my personal document manager was too h...
Back on the blog, I have not posted a lot recently, and I want to change that. Some might call it a new year resolution even. I have been busy last year with a myriad of small projects, most of them software related, some in finance, some in electronics, etc... To be fair, I can say that this is mostly due to AI's help to cross some bridges that were keeping me locked because of lack of time to...
I have a ridiculous problem at my home. When official letters come by, be it for taxes, salary, banking stuff, etc… I usually treat the letter, pay, read it, and then, I don’t know what to do with the letter. Can I get rid of it? Should I keep it? Till now, my option was to keep all of it (in case). And so over the years, I have accumulated a grand total of 3 archive binders that are filled with l...
This last year of 2024 was definitely the year of the auroras in Europe and especially in low latitudes such as France and Switzerland. With several nights where the sky turned red, a lot of people were lucky enough to see the phenomenon and photograph it. As you might now, I like the sky and I like photographing stuff in the sky. And yet I missed all those events, always with the same fashion. I ...
I have been following this new stargazer comet since the end of September. It was kind of a gamble to know if this comet would survive passing so close to the sun and survive. But thankfully, it did survive and what a spectacle it is giving us. It might not be as bright as Neowise in 2020, but this time, I have a better camera to capture it and the pictures are just amazing. Too bad the weather wa...
This year at the AKL Conference was prominently marked by discussions on Artificial Intelligence (AI). The rapid advancements in AI, significantly propelled by platforms like OpenAI and ChatGPT, have captured the attention of key decision-makers in leading companies such as Trumpf and Coherent. The plenary talk particularly emphasized the potential applications, implications, and the urgent need f...
This post aims to provide comprehensive guidance on cleaning optical elements. While there is a wealth of information available online, particularly on suppliers' websites, I want to consolidate all the knowledge I've acquired over the years working with lasers, fiber optics, and other optical equipment, including some tips and tricks....
I have started a project that requires the use of a raytracer. Basically, I hope to make a library for rendering optical paths using raytracing and simulate the result that one would get by looking through the optical system. Hopefully, I would like to be able to write somewhere that I will have a couple of lenses here and there, give the parameters such as the refractive index and curvatures and ...
