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...
So, 5 months ago, I have written a post about Artificial Intelligence and General Artificial Intelligence. You can see the tone from my first post was very optimistic, a little too much maybe, with the hope that things would accelerate soon. I have been using AI a lot recently and I want to report on my understanding of what AI can and can't do and how to use it as effectively as possible....
Continuing my series of post covering my talk from last Christmas about the use of lasers in space and astronomy. The topic today is adaptative optics. I'll explain the reason why we need it, and how it works in simple terms. Enjoy....
So this post and a bunch after this one are from a talk I presented at the end December on the topic of lasers in space and astronomy. The target the audience was members from astronomy groups in the region with some knowledge of optics but not necessarily lasers and the curious people that might be interested but have a physics background from high school. I tried to make it interesting for a wid...
It was a nice cold morning that day, with two layers of clouds, one at the surface of lake Neuchâtel, and another layer at approx 3000m. Just enough to touch the tip of some summits in the prealps. The sun was rising and started to cast some interesting shadows along the way. It is a phenomenon that is commonly called crepuscular rays....
So that is it. I have been, like many others following what is the biggest paradigm shift of the past hundred years. In my opinion, the true next big step in human history that is being taken right now, as some people might seem to realize it, but also as many others simply ignore....
Genetic algorithms are really interesting in my opinion. Not the most efficient, but rather beautiful in the way they work. I especially like them because of the similarities that they share with life. Genetic algorithms are special kind of algorithms that work by modelling how natural selection works in the real world. I shouldn't need to explain how evolution works, but for the sake of it, here ...
The first image from the James Webb Space Telescope (JWST) was uncover a few days ago [1]. This is truely an incredible image, showing the galactic cluster SMACS 0723, which is slowly becoming the de-facto target for newly deployed space telescopes as it was imaged by Hubble, Planck and Chandra before JWST. This image in particular took the JWST 12.5 hours of exposure to be able to see these objec...
