Hey, that's an interesting and uncommon question that I had not seen elsewhere --

They did not release or talk in much technical detail of how the images were assembled, which I'm sure will be done at some point.

I do not think the colors do correspond (at least not deliberately), for 2 reasons:

First is that the image of the Deep Field ("SMACS") contains galaxies at a range of redshifts. For example there may be galaxies quite near us (redshift z = 0 or close to 0) while others are more distant (the arced galaxies in the image being lensed that this image is famous for, at redshift z = 0.39), where redshift is the measure (1+z) of how much the wavelength light has been multiplied.

So regardless of what color mapping you chose, it would not be a perfect fit for all objects in the field of view. For the galaxies near us in the image (z=0), the wavelengths being converted to RGB don't correspond to what we would see in the optical.

Secondly, if it were remapped especially for the galaxy cluster of interest in this image, I don't think the colors are specifically tuned for that either.

In more detail:

Consider the optical color spectrum we see, ROYGBIV, or let me reverse it in order of increasing wavelength VIBGYOR -- and take the "RGB" 3 colors that might make up an image, or BGR to use that ordering -- this spans a wavelength range of say 400nm, 600nm, 800nm.

The imaging filters available on the NIRCam span 900nm to 4400nm (4.4 micron) and there are 29 of them [0]. Researchers choose which filters to use based on what they wish to study. And recall that the imaging sensor actually outputs grayscale only, it is the filters that give it a color view and individual images in each filter are assembled to create a color composite.

According to an example science program designed to take such images[1], the filters selected to be imaged might be 900nm, 1150nm, 1500nm.

If you applied the redshift of the galaxies (divide by 1.39 from the above info about the cluster of galaxies), the above sampled wavelengths in the image would still correspond to redder parts of the spectrum compared to what is visible if we were seeing the galaxies now: 647, 827, 1079nm.

So, no I don't think the color mapping was chosen to be accurate in a scientific sense of seeing what you would see if the galaxies were brought to the "original" view.

I'd like to counter that with the opinion that for most people, controlling their own keys isn't a priority. These are the people that don't even know there isn't any gold backing the dollar, or where money comes from. For these people, Bitcoin offers the option of digitally native money that is well suited for a rapidly digitizing world. They won't feel any problems holding their bitcoin in a walled garden maintained by banks or money transfer companies, and won't consider the counterparty-risk as something they need to be worried about.
CP/M was a lot like MS-DOS. People used the Wordstar word processor on it, you could run a BASIC interpreter and compiler on it. There was an upgraded version called ZCPR3 that was used on a BBS server in my town where you could log in and use the command line.
Look into Taproot.

Once adoption and implementation spreads, you'll realize you can open multiple channels with one on-chain transaction.

This is an evolving space and scaling happens already.

But sure, you can stick to the traditional monetary system where only a select few control the rules.

You are free to adopt Bitcoin. No one will force you :)
Me too. I used it only for copying floppy disks. I didn't know better at the time.
It’s not anti-China propaganda when 1) it’s not propaganda. And 2) it’s about the CCP not China.

But calling it anti-China is a typical tactic to attempt to discredit people.

China credit is the only one knocking on doors and wanting ports to be built by paying off governments to push things through when the courts are saying it’s not a good deal and it has non favourable clauses with the end result of china getting to control the port they built at the cost of the government.
MagicLinks are a mobile nightmare. Mobile email clients use their own browser and cookie jar which consume the session cookie you're trying to put into the user's main browser. This results in users 'never staying signed in' and a lot of frustration.

Sending a one-time code via email fixes this, and is in practice about as easy to use as a link on desktop.

In our app (Loomio) we default to magic/codes, but let users use passwords if they prefer.

This is not the only case. It harms not only performance, but also conformance, e.g. https://developercommunity.visualstudio.com/t/unable-to-move....

Microsoft is stupid enough since the first decision of the implementation impacting the ABI is made. There was no one enforcing such bad decisions shipped into the productions at the very beginning.
Both libstdc++ and libc++ have more flexible rules to preventing ABI breakage.
Have you always tried to run it on the same network? Might be something in your setup. I agree that it can sometimes be flaky, but usually adjusting the settings for the daemon solves the issue for me, either it's connected to too many peers (basically saturating all my available bandwidth) or too few.

Looking around, some projects (like https://estuary.tech/) seems to have successfully stored around ~160 TiB of data on Filecoin (via IPFS), so there are setups where it does work successfully.
Not everyone has a static ip.
Most ISPs prohibit dedicated hosting on a private contract.
Email from dynamic address is usually blocked and rightly so.
Mixing business with private service is not a good idea.
Throughput at home is usually way less and so is reliability.
You’re thinking digitally. PAL and NTSC are analogue formats. In fact that link you cited even says that’s VHS stores the PAL or NTSC signal verbatim and what I described is exactly how PAL and NTSC store audio.

To quote:

> Each of the diagonal-angled tracks is a complete TV picture field, lasting 1/60 of a second (1/50 on PAL) on the display. One tape head records an entire picture field. The adjacent track, recorded by the second tape head, is another 1/60 or 1/50 of a second TV picture field, and so on. Thus one complete head rotation records an entire NTSC or PAL frame of two fields.

Edit: This a diagram here https://en.m.wikipedia.org/wiki/NTSC that illustrates how each transmissions frequency is divided up for different aspects of the broadcast.
AB5 was one of the worst laws I've even seen written then to put icing on the case Uber&Lyft (the ones who there were trying to target) got themselves an exception by going straight to the voters (prop 22) so everyone else needs to deal with the fallout of a shitty law except the target.

The state should work to move benefits away from the employer employee relationship rather then make damn sure you need to work until you die to keep benefits. In a lot of ways it really feels like CA is just trying to offload their job onto private companies.
Once I click the link, it takes me away from my email inbox. That means I have to go back and clean them up later. That's extra work for something that should be ephemeral. No thanks.

I can't quite put my finger on why it's different from having SMS 2FA codes in my Signal inbox, but it feels like more clutter.

> On the opposite end of the spectrum is Elliott Carter. He intentionally tried to avoid repetition in his works.

Aha! So this is what the local classical radio station was playing during its avant garde sets.

Elliott Carter - String Quartet No. 1 is, I find, a deeply deeply irritating work, moreover its advocates are pretentious in the same vein that avant garde jazz muzos are, witness the comment, "Carter always wrote such visceral, intense music for strings. I suspect he really loved the physicality of string instruments." Yeah, right, sure. Call me a philistine, I don't care. Spare me.
Again, please specify exact quantities, I did, it's the least you can do.

No, a body accountable to Congress (the Fed) which publishes quarterly audits is responsible for the currency. They act on behalf of the American people. As opposed to an un-elected, un-accountable cluster of core contributors and mining pools who seem to operate principally to the benefit of North Korea, ransomware operators, Ponzi schemers and various other kinds of criminals - financial and otherwise.

Three Arrows Capital Blew Up and Set Off a Crypto Contagion
But you're approaching it from the wrong perspective: the idea isn't to use the crypto you implement yourself, the idea is to gain a better understanding of how the "magic" works. Of course my hand-rolled RSA/AES crypto is breakable, I know that because that's the default assumption.

It's akin to saying, "you're not allowed to build your own smoke detector because it will be unsafe!". Of course I know that, I want to understand the differences between a photoelectric and ionization smoke detector, how they work in practice, because reading some PDF schematics just doesn't cut it for me.

I honestly don't understand the line of reasoning of all this crypto gatekeeping.

Fun fact: while I was doing my crypto deep dive in 2015, my language of choice being Haskell, I found issues in several libraries, specifically around entropy, and even one library with modulo bias [1]. They were acknowledged and addressed. It was a super fun learning exercise, and seeing all these comments how it's supposedly almost illegal to do this misses the point of people exploring and learning in their own ways.

Why would the dollar be backed by gold? You know that ended in 1933 right? I'd say 89 years is long enough for folks to have figured it out, but I'm always open to surprises.
Trying to write optimized Huffman decompression code for the PlayStation 1 (which by total coincidence happens to be MIPS R3000-based) taught me this. C can go very far if you know how to optimize it, but at some point you are going to run into roadblocks anyway since the compiler will not generate the exact code you want it to generate. It will generate code that _looks_ compact and fast, but can't hold a candle to properly hand-rolled assembly that takes pipelining and asynchronous behavior into account.

And of course this gets worse with CPUs that were not designed to be a target for compiled code in the first place, i.e. the vast majority of 8-bit architectures which for better or worse still dominate the low-end microcontroller market.
I've unfortunately at least tired of "Halcyon" because the youtube algorithm just won't stop playing it to me when I have autoplay on.
The Liquid network comes to mind. Basically, any sort of system that allows users to swap coins and settle back to bitcoin is a layer 2 solution.

Banks could build an SQL database, generate a single Bitcoin address, and tell everyone to deposit there and prove they owned the originating address(es). You get credited in SQLcoins, which are centrally managed by a federation of banks. Once you want to go out, they send coins to an address of your choice.

If one of these layers becomes large enough, it might win the netwerk effect war and become the defacto layer 2 because everyone is on it.
Interesting - thanks for sharing!
> The only scaling solution is MySQL, just like the Bastion of Bitcoin, El Salvador is doing. Always was.

Channel-based scaling is hard, sure. But optimistic and ZK rollups on other chains have both proven to be strong scaling alternatives.
I don't know... Einstein had a lot of love affairs and debated about philosophy with some friends and was very politically active (e.g. he wrote pro-socialism articles for newspapers). In the context of theoretical physics all of this sounds like wasting time to me. Some brains are just exceptionally wired and people are able to accomplish amazing things, given the right mindset and tenacity.
I wish there was a way to read all cookies of the current site and create a bookmarklet that sets them again.

So I could log into GitHub and save the cookies in a bookmarklet.

Then every time I want to use GitHub, I click the bookmarklet and it sets the cookies, so I am logged in.

I dabbled with the idea a bit, but it seems not straight forward. Maybe due to some metadata that cookies carry. They are not just key:value pairs.

For example here on HN, when I type "document.cookie" into the console, I get back an empty string.

That's great for the environment, but in the long term of vanishing block subsidies, not so great for Bitcoin's security, as the costs of 51% or censorship attacks also decrease.
Maybe you are missing the point in regards to what “money” you put in your bank. Coiners can also use MySQL but they just won’t be recording entries relative to another master MySQL database of the central bank and that does seem like a decentralized system with government removed. Technologically it is an upgrade, even if eventually, yes, people will need banks for everyone to use it. But guess what they don’t need anymore …
I think the idea is to stop mail providers automatically scannings the link, which would work until they start scanning the images for QR codes and scanning the links.
I'm the complete opposite. Playing music on repeat ruins it. But if I listen to a song/album relatively rarely, it feels just as good every time. I also notice new subtle details once in a while, and that makes it even better.

I have songs that I absolutely love and have loved for years now. I just make sure not to overdo it.
Two exhausted armies battling for eastern Ukraine. Can there be a decisive blow?
Another relatively new problem with magic links specifically on mobile is that your email client will likely open the link in an embedded browser which is typically isolated from the main browser app and doesn't share the cookies with it.

There are some workarounds for this but they don't seem very secure, plus they add some complexity. E.g. once the backend validates the magic link click, it logs the user in also in the browser that initiated the email send. I think a sort of a phishing attack is possible here. Also the page that initiated it should periodically refresh itself to see if the session was validated somewhere else.

I haven't been able to find any more secure or simpler solutions to this problem. Any thoughts?

Depends on the problem. Sometimes the locality of every state inside the function you write is beneficial, other times it makes it much easier to just not care about the state of a given thing, and let the encapsulation do its job. I just want to use it as per its contract.

> A country ought to feed its people, provide basic services like power and medical facilities on its own, without depending on imports.

Ah, wouldn't that be nice!

I live in the UK, a country that hasn't been able to feed itself using only its own produce for centuries; Napoleon called us a "nation of shopkeepers" because we couldn't survive without trade. Our staple is wheat; but our wheat isn't as good as North American wheat, and anyway we are far from self-sufficient.

We used to export coal, oil and gas; but the North Sea has largely dried up, the coal mines are mostly closed, and anyway coal is sort of un-hip these days.

I wish the NHS would stop putting services out to open tender. Private (overseas) medical companies bid for the business, so that more and more of our health services are provided privately, by US medical companies. We're perfectly capable of looking after the health of our population without overseas help; but apparently our politicians don't think it's a good idea.
It'd be ok, if there is (yet) another factor for doing this, e.g. SMS, time based tokens, and you'd need 2 of them to reset the 3rd. Cumbersome to put it mildly.
If you'd take a passwordless login with FIDO2 (now promoted "Passkeys" by Apple and Google) it would mainly require to use FaceID / Windows Hello / Fingerprint / PIN ... or whatever your devices deem necessary. Could be used on any and cross-device.

You seem to have a very US centric worldview. Maybe ask some Turkish savers how they feel, or any number of endless examples worldwide where saving in their own government fiat isn’t a good idea.
> As opposed to an un-elected, un-accountable cluster of core contributors and mining pools.

These people don't control bitcoin. Developers and mining pool operators have their purposes in the network (designing new features and timestamping transactions respectively), but it's the users and node operators that validate the rules of the system. A code change to inflate bitcoin by 100% will never be adopted by node operators unless nakamoto consensus is reached.

> Even a few years later, it still surprises me that people in the Bay normalize this type of activity but I guess Stockholm syndrome is strong in the average person.

California born and raised: California was never safe since it's inception as it was always the most renown frontier in the US; it's just where fortunes could be made in a person's lifetime. If you are honest with yourself you also came for the money/title/status and told yourself that because you live in a certain zip code with billionaires it also somehow confers some sort of safety on to you... I saw this play out during COVID and so many who thought that they were somehow residually part of the elite got a rude wakeup call when all the riots and crime shot up. The smart ones took their real estate exit money and left for good.

If I'm honest it's like a form of Stockholm syndrome, but it's more like a trophy wife staying in a toxic relationship because she'd have to get used to real life once she ventured outside of a very persuasive bubble existence--at least in the bubble she can take all the xanax and cosmo chasers to normalize the craziness around them. Their is a reason why Cyberpunk 2077 was based in California, the lore just lends itself so well to it and it's why I think it resonated so well for those from there.

I also left, and now live on the other side of the World, and I really have no desire of going back until <50% of you people leave so I can finally go back home.

>Studies of brain damage: If 10 percent of the brain is normally used, then damage to other areas should not impair performance

This is unbelievably naive to use as some sort of proof, using 10% does not imply that its 10% of the physical organ. Rather 10% compared to what one could do with better training, improved lifestyle, etc. And this does not have to be purely intellectual, it can be imagination capabilities, communication skills or hundreds of other things which a particular individual did not develop fully.

Bitcoin’s security has not changed.
The main reason we don’t see a lot innovation in this space from the streaming services, is that using the music inside an interactive experience such as a game requires a different license.

It would be fairly simple to make a tap/swipe/press game with a similar experience to rock-band, automatically for all music on a service. But having looked into this, together with a few major music services, the license cost made it almost impossible in practice.
I have similar thoughts but they can be broken into two distinct feelings:

Ideally everyone would routinely have their attention called to the sword of Damocles, or at least listen to Dan Carlin's Destroyer of World's once every few years. So I should take what I can get from the NYC ad...but having one produced seemingly apropos of nothing with the tone of an Ad Council billboard creeps me out too.

I also want people to be respectfully fearful but fear populations who are afraid.

Please re-read my post. I specifically speak of people using money without being aware of all the specifics. Noting that the dollar is not backed by gold.

How do you handle the tax implications of streaming sats?

As far as I know, every payment with Bitcoin triggers a taxable event?

Do you record a gazillion log entrys "Paid $0.0000145 for listening podcasts, Paid $0.000142 for listening podcasts ...", crunch all the numbers and then at the end of the year put that gigantic list into your tax declaration?
