you can also make this with onion, and that is what I have made mostly. You can also store it for a reasonable amount of time if not oil fried, and over here (where i belong) we even have a spice which is essentially this onion chip powder

well, minced may not have been the best word. the size should be close to cross section of smaller confetti. Cabbage has very high water content, and if you dont get them small enough, they would not get crispy.

We have a peas and cabbage (essentially cook both of them in a pan/wok with mild spices, you can add carrots, tomatos or onions to your liking to increase the volume or add more textures), you can prepare dim-sums or momos (refined-flour or rice flour sheets filled with vegetables(usually cabbage, carrots; minced) or some meats, steamed). You can pickle the cabbages, or even make chips out of them (mince fine, then sun/oven/microwave/air-fryer drying to a point where they loose about 40-50% by weight/volume of water, then bake or fry to your preferences in mild spices)

it is a black hole

I maybe am completely wrong here, but i think this the article https://jasmine.nao.ac.jp/2024_2/EN/press_release_20241025_en.html

In the figure 3, the doppler shift considered seems way to high to me. If i get it correctly, we should be able to see the ring also also from top and bottom, so the center also should be in the plane of us viewing. the simulations seems to be from POV of someone much closer to BH, but we are really far, and then the effect should not be this much evident (I think).

Anyway, it is not necessarily this image that i am fond of. In a abstract sense. we have the raw image data, and just need a good image encoding algorithm to process this data. The fact that we got this raw data is amazing.

We as in humanity may visit it, but we who are alive right now have a really slim chance

epubs are effectively self contained html files, but the scripting is not there (afaik)

to add to it, you “can” add anything arbitrary, but it is not same as downloading a executable. Due to some really weird reasons, many parties were interested in using pdfs like interactive forms, for example some government forms, where you can fill a field, and you can add scripting to execute upon input and convey back. It is somewhat like javascript for pdfs, and then the onus is on the pdf readers to be compliant enough to execute such scripts, and provide enough access to your system. Many minimal pdf viewers do not implement these features, or for example pdf viewer in firefox has the option to execute, but disabled by default.
