For #life to develop on a #planet, certain chemical elements are needed in sufficient quantities.

#Phosphorus is vital for the formation of DNA and RNA, which store and transmit genetic information, and for the energy balance of cells.

#Nitrogen is an essential component of proteins, which are needed for the formation, structure, and function of cells.

Without these two elements, no life can develop out of lifeless matter but there are also more profound consequences.

During the formation of a #planet's core, there needs to be exactly the right amount of oxygen present so that phosphorus and nitrogen can remain on the surface of the planet.

This was exactly the case with Earth around 4.6 billion years ago—a stroke of chemical good fortune in the #universe.

When #planets form, they initially develop out of molten rock.

A sorting process occurs during this time: heavy metals such as iron sink down and form the core, while lighter metals form the mantle and the crust.

If there is too little #oxygen present during the formation of the core, phosphorus will fuse with heavy metals such as iron and move to the core.

This element is then no longer available for the development of life.

On the other hand, too much oxygen present during core formation leads to phosphorus remaining in the mantle and #nitrogen being more likely to escape into the #atmosphere, ultimately being lost.

Blacksky has already built their own ATProto stack that's fully independent from Bluesky.

Now Eurosky is making progress as they roll out their own PDS.

I see more independent infrastructure springing up on https://atp.fyi/network, including AppViews.

For anyone hoping that we'll get another wave of people coming to the fediverse once Bluesky folds/enshittifies, that might not necessarily be the case as people will have more options to stay in the Atmosphere.

If there's one thing that unites the #Fediverse and The #ATmosphere it is this: Substack is ⛔👎🏽🙅🏽🚫😒😤

Use Hugo (with ATProto & ActivityPub plugins), WriteAs, Offprint, GreenGale, Pckt, Leaflet, Ghost, WordPress (with AP plugin).

Case in point, from a recent AT Protocol developer call:

> "choose a PDS host" is a surefire way to lose the user

Also interesting, some thoughts on sustainability and funding for ATProto apps:

> "I think eventually there are going to have to be more paid levels of atproto apps. I know I can't logically continue to burn money to support the infra indefinitely."

Reading notes from the event that mention how Twitter was an improvement over RSS in terms of user experience.

Another good example would be people switching from pirating media over to signing up for streaming services. It was the easier option.

With Blacksky recently achieving full independence from Bluesky, and other projects following behind, it'll be interesting to see who will handle federation better.

Change of pace. Now I’m listening to @iameli of Streamplace fame #FOSDEM #ATmosphere #ATProto

Gander Social (pending #Atmosphere /
#Bluesky social network from #Canada 🇨🇦) is losing two individuals due to…differences of opinions‽

👉🏾 Folks, some news to share on Gander Social from [Amber Mac] and me. We are both not involved with Gander as investors or advisors. We respect their ongoing efforts and wish them well in the future. https://www.threads.com/@arlenedickinson/post/DUGMi9CElB-

@arlenedickinson & Amber Mac appear to have parted ways amicably, & Gander (https://gander.social) is raising funds directly from users.

Another day, another social platform embracing the #Atmosphere (it is currently in Beta).

It is called Gander Social, & it is hosted in #Canada 🇨🇦: https://gandersocial.ca/

Unlike #WSocial, Gander Social will use the standard Atmosphere protocol, which means they will be able to easily interact with #Bluesky users. They plan on launching sometime this year.

I am curious as to why they chose Atmosphere over the #Fediverse.

Discovered via @grrlscientist (on their #CounterSocial account).

Interested in setting up an #ATProto account on an instance that's not #Bluesky but can't find any. Do open ATProto instances exist? Is @surf running its own instance on the #ATmosphere?

#decentralize

Hm, so it might actually be powered by ATproto?

Interesting.

What are you looking for in social media? (1/N)

https://privacy.thenexus.today/what-are-you-looking-for-on-social-media/

Since you're seeing this on fedi -- or Bluesky, Blacksy, or elsewhere in the ATmosphere -- you already know the value of alternative social media that's not controlled by techbro white supremacist CEO's who make money by exploiting their users and working with their cronies in authoritarian governments.

But, what we have today is only the tip of the iceberg of what's possible.
