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...
I was at AKL 22 a couple of weeks ago: the international laser technology congress at Aachen, Germany. I was present for the interesting technology conference and the live presentations at Fraunhofer ILT....
Time flies: we are already in May, and I haven't got time to even post these pictures in time......
I wrote last year about the effect of CME on the thermospheric density and what are the effects on satellites inside the thermosphere, typically at the altitude of the Starlink satellites. You can find this post here....
So this post is a simple shout-out to some other blog I discovered a few months ago. At the time, I was browsing hacker news and saw this post about optics. Great! I love hacker news for this. They mostly have posts about computers and programming but every now and then, there is a post about something totally unrelated, be it optics, physics, environment, etc... but always some quality content. T...
I have always been interested with optics and vision. My path led me to a more technological approach of optics, aka photonics, but I still am fascinated by the process of vision. How the image is formed in the eye, how it is interpreted in the brain and so on. This led me to learn a few things that apparently are not so well known about our own eyes. One of these things is the subject of this pos...
I know, this comet was seen 1 and a half year ago, but I didn't had a blog then, so I have to do it now......
I wrote about Carrington events here, just a few days before the solar cycle 23 unleashed some strong storm with an X1 flare the 28th October and several other CMEs the next days... Fortunately, the impact on earth was minimal: It was a mostly a miss. But it sparked some wonderful display of aurora in the last days of October. See here and here for some nice images....
