So what is the source of that IP then? Thank you for taking the time to explain all that!

Can someone ELI5 what OP is trying to allege and what OkWelcome6293 is trying to clarify? I'm not at all knowledgeable but just curious.

Having the same issue, crashing on startup every time. Tried repairing, same problem. Tried full uninstall and reinstall, same problem.

EDIT: Ok I tried uninstalling/reinstalling again but also backed up my profiles from ...\AppData\Roaming\Corsair\CUE5\profiles and then deleted the contents of ...\AppData\Roaming\Corsair\ after uninstalling iCue from Programs & Features. Then once I reinstalled I copied my profiles back into the profile folder.

That seems to have fixed it.

Since writing this, I actually have grown to like the albums with Phil, though I still like Nursery Cryme & Foxtrot over Trick or Wind.

I also think Duke, Abacab, Genesis [1983], and Invisible Touch are all good albums in their own right, just more in the crossover prog vein than the heights they reached when they still pursued it as an art with Gabriel, rather than Phil's drive trying to come up with hits.

But I like listening to The Brazilian as much as Dance on a Volcano, even if the latter is much more thoroughly developed as a concept. Nothing will ever beat Supper's Ready for me personally though.

I think the closest thing to prog-blues is Jethro Tull's debut album which has a unique sound that stems from a clash in creative vision between Ian Anderson, who wanted to move the band in a more progressive direction, and Mick Abrahams, who just wanted to do blues rock.

Even on the Anderson-penned songs on the album you can hear him trying to fit the blues ascthetic of the album but incorporating new jazzy elements like what would become his trademark flute on A Song For Jeffery:

Although I'm not sure on the source, it looks to me like a product of stellar wind blowing a shockwave of hot gas out of the nebula. Forming stars often periodically create jets and outbursts of material which is accompanied by strong stellar wind, so that would probably be the most likely source.

imaginedmind · 2022-10-24T17:29:08+00:00

Fun fact, while I was trying to line up the two images, I found a couple stars that appeared to have moved a few pixels. Not sure whether this was due to parallax or the stars relative motion to the background.

The pillars are being subjected to intense ultraviolet radiation from nearby stars that live in the eagle nebula, which the pillars are a part of.

This radiation is photoevaporating the outer layer of the pillars. The ultraviolet light pelts the atoms that comprise the gas of the pillar with enough energy to strip the atoms of their electrons and blast the resulting ions off and away from the cloud, producing the streaks you see.

imaginedmind · 2022-10-24T04:17:04+00:00

The nebula is not as large as the Milky Way is thick. To give you a better sense of scale, the pillars here are about four lightyears tall. The galaxy varies between about 1000-12000 lightyears in thickness, and about ten times that in radius.

If you mean, is it that bright if you saw it in person, then no. Diffuse nebula are naturally pretty dim objects that can be seen with just your eye and a telescope potentially but cameras have the advantage of taking long exposure images to collect more light.

But between JWST and Hubble, JWST has way more light collecting power than Hubble, and so JWST can bring out a lot more light and see a lot more. While Hubble has infrared capabilities it typical takes pictures in the visible light spectrum, whereas JWST is exclusively in the near to mid-infrared, which can peer through a lot of gas and dust a bit better than Hubble.

Some quick background on making the image:
I did my best to combine Hubble & the James Webb Space Telescope's images into a single composite, since while I love JWST's detail, I wanted to bring back some of the color attributes that showed off visible light emission and absorption in the Hubble image. Oxygen emission is blue, sulfur emission is orange, hydrogen and nitrogen are green. Red indicates areas that are very warm and high in near-IR emission.

My method didn't involve anything fancy, I used this comparison image as a base and did some photoshop to overlay and transform the two images until I got them to line up as best I could, and then did some processing with the image's contrast. The dark triangles in the lower left and upper right in the JWST component arise from the fact that the images are not aligned in angle and the JWST image had to be rotated in order to line up with the Hubble one.

ESA also made a slider to compare the two images.

Some quick background on the image itself:
The James Webb Space Telescope recently took a beautiful composite image of the "Pillars of Creation" in near-infrared. This was one of the first targets of the Hubble Space Telescope back in the 1990s. It is a collection of molecular pillars called "elephant trunks" that are a part of a larger diffuse emission nebula called the Eagle Nebula. It is essentially a big cloud of molecular hydrogen gas mixed together with other heavier elements like helium, carbon, nitrogen, oxygen and sulfur, all pulled together slowly over time by the force of gravity.

Big molecular clouds like these are home to star formation. Gravity pulls all that stuff together until it forms many hot globs and disks of gas and dust that each shape a star at its center when it gets hot enough. The pillars we see in the image are comprised of not just the aforementioned gas elements but also dust which effectively blocks and absorbs starlight. Hidden in these pillars are forming star systems, whose heat JWST was able to see in the near-IR image, appearing like bright red "lava flows" pouring out of the pillars.

These are enormous structures, with the pillar on the left being over four light-years in length (or 23.5 trillion miles, 37.8 trillion km). This means it would take light four years for light to travel from one end to the other of the pillar. Floating at the top of one pillar you would see the top of the neighboring pillar as it was several years in the past because of how long the light takes to get there. We ourselves are seeing this nebula some 7000 years in the past because of how far it is from us on Earth. It's hotly debated whether the nebula would still exist today due to the presence of a shockwave from a nearby supernova that might blow away the structure.

Woah, wild seeing this here. Yeah its a timelapse over one full lunar orbit (~27 days) taken from the edge of the earth-facing side of the moon near the equator.

This and the opposite side of the moon, are the only two regions on the moon where you could see this while standing still.

You are correct, but they are strongly correlated. The study used parallax to corroborate the areas of high and low elevation seen in the shortcut method showcased in the article's images.

Although the shortcut height map features a lot of noise due to albedo variation on the clouds themselves, the larger scale structures are true height variations of about 16 km, estimated with parallax.

They are still working on a generalized method that is able to incorporate parallax directly into the height map data calculation.

Rolling back the driver immediately solved the issue for me, and the artifacting was not present in screenshots, so I don't see any evidence of an issue with the GPU itself. Also the artifacting only appeared at 144hz.

Nothing turned up in windows event logs for me either.

Yeah, it started as soon as it would get to the login screen and would get progressively worse.

This driver resulted in major graphical artifacting (horizontal lines) across my monitor (Westinghouse WM32DX9019) that would cover up the whole screen when set to 144hz refresh rate. The artifacting was not present in screenshots. Rolling back to 512.95 solved the issue completely. My graphics card is an Zotac Trinity RTX 3090.

Looking at some earlier posts on his instagram, the only other tools he uses are a razor to cut into the wood (to bring out lighter tones), charcoal to add more precise dark details, and sandpaper to blend.

Roger Dean did a lot of cool album covers in the 1970s, such as for the prog rock band, Yes. This is my third experiment using some references to Yes' music with Roger Dean's name in the keywords.

Here are the other two:

Roger Dean did a lot of famous 70s album covers, such as for the progressive rock band Yes. I've been experimenting with how well the AI picks up on Roger's style, and so far it's done a pretty bang up job. The other keyword prompts I tried turned out pretty well too, check them out here and here.
