Low-Cost, High-Gain: A Smart Electronic Eyepiece for Capturing the Cosmos
We’ve all seen spectacular pictures of space, and it’s easy to assume that’s how it looks to the naked eye through a nice telescope. But in most cases, that’s simply not true. Space is rather dark, so to make out dim objects, you’ll need to amplify the available light. This can be done with a larger telescope, but that’s an expensive route. Alternatively, you can observe objects for longer periods. This second approach is what [BLANCHARD Jordan] chose, creating a budget electronic eyepiece for his telescope.
This eyepiece is housed in a 3D printed enclosure designed to fit a standard 1.25″ telescope focuser. The sleek, ergonomic enclosure resembles a night vision device, with a 0.39″ screen for real-time observation of what the camera captures through the telescope. The screen isn’t the only way to view — a USB-C video capture module lets you connect a phone or computer to save images as if you were peering through the viewfinder.
The star of this project is the IMX307 camera module, which supports sense-up mode for 1.2-second exposures and increased gain to capture dim objects without post-processing. This sensor, commonly used in low-light security cameras and dash cams, excels at revealing faint celestial details. All combined, this project cost under 200 Euros, an absolute steal in the often pricey world of astronomy.
Don’t have a telescope? Don’t worry, you can build one of those as well.

I enjoyed and appreciated reading this post.
"I realized almost immediately that GNU/Linux and FreeBSD were so similar they were completely different."
This right here.
My initial impression with #FreeBSD in 2006 was quite similar. Of course, #Linux back then was a much different beast than what it has evolved (mutated?) into today.
Had I not pursued Linux system administration as a career, I *probably* would have stuck with FreeBSD.
We can make all the technical comparisons between the two OSes all day long but what drove my interest and enthusiasm are (1) the documentation and (2) the community.

@peacelink ma non sono riuscite ad evitare di sbavare mentre lo dicevano

@stefano Don’t bother filing a bug report. They will act stupid. Probably they are stupid about it. They think it is a bug. Actually the author probably wrote a program he knew was not a solution to the problem but which he could do on deadline and which was good enough for his job at HP.

@stefano Here is something new for you to be upset about, though, which affects everyone, Linux, BSD, illumos alike. I have been upset about it for over 20 years.
Read ‘man 5 fonts-conf’ or whatever your equivalent is. Read it carefully under ‘FONT MATCHING’. What it says is that a font is not chosen as you wished, but instead RANDOMLY. You are only LUCKY if you get the font you wished.
And if you experiment long enough you will find this is true.
Fontconfig is unfixable and must be scrapped.

L'Ucraina ha sviluppato nuovi missili balistici FP-7, analoghi all'ATACMS, ma due volte meno costosi
I test si stanno muovendo verso una nuova fase, i missili saranno testati direttamente in attacchi in Russia

@quinta non solo lo fa, ma se ne vanta pure.
