Are you seriously suggesting that every mention of a negative issue needs to be a self contained and cited polemic piece? Stop being absurd. If you want to talk specifics, make a specific objection, or at least narrow in on an issue you wan

Congratulations, you've discovered that I'm commenting on an internet forum rather than submitting something for publication. My assessment is based on my own reading, and on being involved in conservation efforts and trying to st

That's some excellent wishful thinking, and I hope you're right. Meanwhile, I've read plenty of articles suggesting that we're likely in for unavoidable and hugely disruptive warming, at the very least, and I don't

I'm not 100% sure what you're getting at, but I don't think it really addresses my point. Much of what you've said could be read as just a descriptive reason why the human world is the way it is - no objection there, exc

More cynical take: because most societies have to go through this experience, most societies don't make it to "advanced". That's one of the ideas behind the "Great Filter" hypothesis.

Pick an area of science which intersects with human development and I'll find you something - the underlying truth is that we can't hope to disrupt such a huge percentage of our biosphere without nasty consequences, and we can&#x2

The near universal consensus of people who study natural systems is that we’re way, way, way behind. Unfortunately the science is pretty bleak.

This isn’t an issue of fashion, it’s an issue of cognitive load. Bad audio is distracting, and requires more mental work to process. It’s fatiguing, and as someone who spends an absurd amount of time doing video conferencing, it makes a

But what if we drop the word comprehension, and we just go with “functional approximation X -> Y, computed from a finite dataset, which minimizes a predictive risk “? It’s unclear why compression is necessary there, except as a practical

It’s not binary is the point.

What’s the issue with newer EdgeOS? I thought the cloud crap could be disabled.

I think you're missing the bitterness that comes from growing up with a set of coping mechanisms and losing them. Moderate Christianity, taught by moral and good people, nevertheless can lead one to use the thought of eternal life as a

It also just seems sooooo slow. I also drop to the terminal for these tasks 100% of the time - including search. I’ll Google for software, and then dnf search to find the specific package if it’s offered.

Astrophotography is less like photography and more like scientific data acquisition. To specifically answer your question though, this is "1250 hours of exposures" and not "a 1250 hour exposure".

This is true, but it's also true that making faint features visible (like the dark, dusty regions) often requires the use of local contrast, sharpening, and masks. Also, in the case of this specific image, I think it's important t

by gbrown 6y ago
In astrophotography there's (almost) no such thing as "natural". It's definitely an aesthetic, but it's based on "real" data.

I use it with Fedora happily, and for work I have to use Zoom daily. I did have to replace a fan with one from Aliexpress due to rattle, but haven’t had issues since.

To be more pedantic, you are incorrect that this is only true for Andromeda. Several other galaxies are visible with the naked eye under excellent conditions, though they can certainly be challenging. These include M81 and M33.

That misses the point - jets are one mechanism whereby the matter can lose some energy and fall in, but they occur due to the high energy of accreting matter, and their existance does not solve the problem of the growth rate of these things

Mirror size is the issue - until we can easily manufacture huge, incredibly precise mirrors in-situ, space based will never replace ground based astronomy.

Not starless, surely. Stars like Sirius and Betelgeuse should be visible just about anywhere, and that gets you 8-500ish years back at least.

No, it means what it says - the growth rate is too high for known mechanisms, so they’re looking for explanations. The mass in the universe isn’t the issue, it’s that there are limits on the growth rate of black holes which grow through acc

Well anyone can see a few million years back in time just by going outside on a dark night and looking at one of the nearby visible galaxies with their eyes. Knowing that this is what is happening is indeed a great achievement.
