supernovae··on ‘Things are going to break’: Texas power plants are running nonstop
We never transitioned, wind was just the most economical growth opportunity for generation and it works really well in that regard. Just because we have increased wind doesn’t mean we don’t need to increase base generation. Not sure why you frame it like this.
supernovae··on ‘Things are going to break’: Texas power plants are running nonstop
no idea, but turning them off saved 1,500mw - our senators have been working hard to get more to move down here. It’s all power arbitration to me anyway.
supernovae··on ‘Things are going to break’: Texas power plants are running nonstop
the thing is, wind in general has far surpassed its expectations.
supernovae··on ‘Things are going to break’: Texas power plants are running nonstop
1,500 megawatt is what i heard, so about 2% of grid and growing.
supernovae··on ‘Things are going to break’: Texas power plants are running nonstop
it’s unfortunate many local utilities in Texas actually punish for solar. It’s a good thing off grid solar and battery storage is really coming down in price.

we haven’t even hit our hottest month and yet and this week alone the grid hit an effective 100% utilization rate and was only saved by asking manufacturers and crypto miners to shutdown. Toyota has to close their plants by 2pm. That’s pretty messed up

The simple answer is simply because of the physics of the scope, the support arms cause diffraction spikes. The hubble has them too but is a smaller mirror and different support arrangement. Super common on consumer scopes such as RCs, Newts and big tube scopes that aren't RASAs

supernovae··on Inflation rose 9.1% in June, even more than expected
Prices are dropping or being moved around.

For example - amazon goods - prices haven't really changed much but its so affordable to buy at amazon because of the negligible shipping. 5 years ago it would have cost you $150 bucks to same day/overnight a package. Today i can order batteries, dog food and cleaning supplies and have it show up by 3pm. So pricing has "changed" if you ask me - you don't get the cheapest goods compared to other stores but the overall price is low because it shows up to my front door super quick and saves me time/money in other places.

Beyond that - i'm seeing pricing settle. I build lifepo batteries, prices were way up but coming down. Construction goods are trending down. Lumber is up and down variable on supply but coming down.

Dining out prices have gone through the roof though... just had a terrible meal the other day and for crappy food it was 48 bucks for 2 people. So I'm just gonna cut out dining out unless i know i'm paying for premium. I'd rather spend 150 bucks for a meal i'll never forgot that is a 3 hour experience than 50 bucks for something thrown in a microwave and slapped on the table. So there is the value vs reward thing to think of here..

but other things - 3d printing is cheap, hobbies are cheap... cars? expensive, I invested in an EV bcause electricity is cheap and speaking of electricity Solar and home battery systems are so cheap now compared to before that i offset some costs of cooling by just buying new AC, new efficient appliances and using new panels.

what prices are you seeing stay up? even fuel is below 4 bucks a gallon and struggling to stay up

supernovae··on Inflation rose 9.1% in June, even more than expected
I find this disappointing because it basically says "anyone who works for a W2 will cause inflation if they are successful"

That shows to me that capitalism is broken if success means inflation. We should be able to swim in cash reserves and safety and not be penalized for it.

I use PixInsight myself, but you can do a lot on photoshop and a lot of people will take the output of PixInsight to touch up in photoshop.

Modern sensors are amazingly low noise. 10 years ago, I used to have to calibrate out darks, bias and flats just to remove my sensor noise. Now with modern CMOS sensors, people still do that but it isn't as necessary and you can overcome much of the sensor noise by capturing enough data - and that's where JWST just dominates. THere is nothing impeeding the data causing noise.

Shot noise is easily removed by integration, Read noise on modern sensors is almost non existent and easily calibrated out, dark current is extremely low, bias, hot and cold pixels are all things that can be removed with calibration and integration and with space telescopes cosmic rays are probably the most annoying thing but if you stack enough images they integrate right out.

But back to photoshop, the final images are just publishing art. I use pixinsight myself for all the heavy lifting, pixel math, integration and calibration but sometimes go out to photoshop for cleanup - especially for web/print.

We already calculated the gravity and mapped it out. Here is a paper on some of the research: https://www.kiss.caltech.edu/papers/darkmatter/papers/the_da...

What i think is pretty cool is that the gravity lens actually allowed hubble to see galaxies it may have not ever seen had there not been a gravity lens and now that we have JWST we see many more distant galaxies (and more of the same galaxy reflected in more positions)

supernovae··on James Webb first images – complete set of high resolution shots now live
The mind blowing part is that many of those smeared galaxies are the same galaxy just "smeared" around the curvature of space so it shows up in multiple places as we perceive it since its been warped by the gravitational mass/dark matter so strongly.

Visible light looks like this: https://www.adamblockphotos.com/ngc-3372-carina-nebula.html

But that's with a telescope and long exposure & image stacking. But still in RGB as humans would see it.

I guess there would be a point that if you were not so far away, but still far enough away - it would light up the sky. This is emission nebula after all.

BUt if you were in it, it would be so diffuse that you wouldn't know it... perhaps a weird glow if you were near some of the forming stars.

While the JWST uses the red end of the human visual spectrum and narrow filters these objects are still broadband and can be imaged as such. Adam did an excellent job on widefield https://www.adamblockphotos.com/ngc-3372-carina-nebula.html and there are lots of deep field images in RGB on Astro imaging sites. The detail is phenomenal with JWST but a lot of people are saying one wouldn't see this with their eyes or with a color cam - and they're "wrong" (its complex). Your eyes just don't "collect" photons like a camera, but a color camera would see this nebula beautifully... We use NB in hobby Astro imaging a lot just to reduce the impact of light pollution.

supernovae··on Private equity may be heading for a fall
No, they weren't. By 2006 home sales were already down 10%, Homeowner ship was down in 2006 vs 2005, manufactured homes were down 11%, even apartment dweellings were down 2.4% from 2005 and new construction on apartments was down 5.9%.

2006 was nothing but four quarters of constant decline in housing.

We haven't seen quarter after quarter decline yet and leading up to 2008 it was ~3 years of quarter after quarter declines.

What we have seen is huge market corrections and we're now seeing healthy price corrections in real estate and a slowdown in home buying/selling. Job market still showed growth, retirement savings are down over peak, but still largely doing well over trend.

I'd be fine with consumer confidence shrinking to force pricing back down. I see gas is < $4.00 a gallon here in Austin now (yay).

Corrections are great...

The only way we'll see another 2008 is if it turns out the market was fake to begin with. The only fake market i've seen is crypto. If people back out of that, that won't hurt USD much (it could help) and if people re-invest in crypto well then they re-invest in USD for everything necessary to support crypto (markets, electricity, GPUs/ASICs so on and so forth)

supernovae··on Private equity may be heading for a fall
I'm not seeing that trend. We haven't even seen down side in pricing or a full downaward trend in in new construction and most of the modern developments are doing mixed developments of retail, business and living spaces.

There were a few % points drop at times - but most of that was supply dynamics and supply pricing.

so much demand for commercial real estate that prices are up 24%

It's probably a good thing for the market to cool

supernovae··on Problems at Roblox
I love my kids, but at the roblox age, kids are assholes. Self Centered. Egotistical assholes. Their brains don't know any better and while you can teach them everything you could hope they learn, they have this chemical in their body that basically says "my parents are idiots and I know better" and they're going to make mistakes and do stupid things. The amount of unfettered mistakes and stupidity one can do on the internet is boundless. I didn't grow up with such boundless access to the world.

These roblox systems do not reflect reality at all as we used to know it. Kids used to draw something that their parents would hang on the fridge and they didn't make 350 bucks from it, nor did the entire world have access to my fridge to see their creations. If we played D&D it was with 4 kids in the same street or same neighborhood - our worlds were much smaller/finite. If some rando approached us - it was weird and we knew to say "no thanks" and move on - bit in the context of the internet - everyone is a rando.

At first, it was kind of cool to see kids create roblox groups, then use those groups to sell things and distribute the funds - but they became infiltrated and before long kids were addicted and they had to login and they had to create and they had to work.. and they stopped being kids... and old farts manipulated and took over these communities to profit off child labor.

But.. from a parents perspective. It just meant turning the roblox off. Pulling it cold turkey. You can block chat - then they hop on discord. And discord just makes things infinitely worse. Block discord and they're on twitter, instagram, pinterest, facebook, snapchat, tiktok.

THat desire for instant gratification and community at all costs then has them looking for other people in similar situations and that usually means self diagnosing things, searching for aesthetics or trying to define themselves in really weird ways with such fluidity that no one can keep up. Not even them.

So yeah, you can't teach this to kids.. Parents aren't equipped to handle it either.

You know, from having lived through the 80s and several crashes in between I'd say what sucks today isn't the financial/jobs markets or economy but rather the people and how terrible we've become politically divisive. That's what I see.

That 20% market drop from high just seems to be a correction and it was needed because that market high was based on crazy stuff anyway. But that 20% didn't do jack to 99% of the country. We didn't win when it went up, but inversely, we haven't really lost on its way down.

Sure, inflation sucks but if you ask me - stalling our insatiable appetite to consume is probably a good thing.

What's the concern with commercial real estate?
supernovae··on Private equity may be heading for a fall
These groups of people already have a negative discretionary spending capability, they're not going to swing the markets. The markets don't even really jive with working class/normal citizens anyway.

I don't see any areas of the economy where there will be wide spread layoffs besides crypto markets and even then, those people will be swallowed up elsehwere.

supernovae··on Tech layoffs keep stacking up
Sure, there are differences... but in the 80s, i remember people burning their houses down to collect insurance money because of things like high interest rates, high inflation and the savings and loan scandal amongst following a huge energy crisis, a huge escallation in the cold war, political strife and so much more.

As for the fed, they're raising interest rates to cool things off - hopefully people are investing in ibonds and just maybe savings accounts will see more than 5th of 1% again so there are some upsides.

Layoffs? they're happening but unemployment still went down.

supernovae··on Tech layoffs keep stacking up
Amazon recently stated they're going to run into an issue of having to re-hire people they fired/let go - the workforce isn't that diverse.

The best thing that could happen to Amazon is unionization. Stability in their massive churn and perhaps more stability as a company.

Netflix isn't an NFT and just because they have competition now doesn't devalue them as first mover with millions of subs.

I don't see this at all in the tech industry. Companies are actually scouting for talent.

Heck, my family in service industry says anyone with a pulse is hired these days.

The 80s,90s and 2000s would like a word with you.
supernovae··on Tech layoffs keep stacking up
the only parallel to 2001 i see is crypto. The rest of tech is on pretty sound footing all things considered.

The thing is, We don’t have fewer options. We’re just exploding over with talking heads telling us we can or can’t do something.
supernovae··on Cancelling Student Debt Is Unforgivable
I’ve never gone to college or had any student debt and I believe we should cancel many of the loans.

I don’t know why people feel in opposition to helping people who have gone to school.
