Our sun is getting a little faster these days, and maybe we’re rewarded The best screensaver image ever taken. Incredibly detailed photo of sunlight in January by Daniel K. The Inoi Solar Telescope is a 4 meter device with adaptive optics that can capture the sun from near-infrared to visible wavelengths and fix surface details up to 20. Km Photo of distinct “eye of sorone” shape, showing massive convection cells around dark sunlight; The accompanying animation shows the motion of the plasma through the oppressed lines of the magnetic flux causing the formation of sunlight. It’s worth seeing, and it’s more interesting about the technology that went into capturing it.
With the dust around GitHub YouTube-DL DCMA removal in the minds of the open source community, GitHub Universe 2020 An interesting discussion about maintaining open source software projects It is a must see. The challenges that YouTube-DL administrators face in operating the device and their efforts affect the people and groups who depend on them.

Video is Inigo quilts, and goes through the basics of rendering images using remarkable SDFs or signed remote functions. At first, it seemed like a bit Drawing an owl, But it is interesting to note that his descriptions of mathematics and each element of the animation are just a different formula. What’s more, there it is A live rendering tool There you can check and edit the code. Alas, my changes made things worse, but it was fun and instructive to play with.
