So if I understand this correctly, the galaxy above in the paper is at Z=14.4 and that means it appears in the sky about as big as if it were a very small Z or roughly 350 megaparsecs away?
I'm not sure a person wrote this website, but FYI on Firefox Nightly the text of the tweet is shown below the blocked tracker in a box labeled "Content from blocked embed". It doesn't have images or longer posts, so not that useful for this specific website, but it's a nice feature. It also gives you a link to the tweet so you can easily open it in a private window or XCancel if you want to.
Wow I didn't see that. Usually it's forbidden in the terms of agreement between the merchant and the payment processor to add a surcharge for using the card so everyone else ends up subsidising it.
Vienna/Austria is such a strange place wrt payment right now. Some places are cashless, many are cash only, many are card only above a certain amount. I had one lady running a ramen restaurant accept instant SEPA.
And it's going to be interesting tax wise when they remove the requirement for receipts on transactions under 35 EUR.
I find the arguments from those who say there is no crisis convincing. Progress doesn’t happen at a constant rate. We made incredible unprecedented progress in the 20th century. The most likely scenario is that to slow down for a while. Perhaps hundreds of years again! Nobody can know. We are still making enormous strides compared to most of scientific history.
Although we do have many more people now working on these problems than any time in the past. That said, science progresses one dead scientist at the time so might still take generations for a new golden era.
Funnily enough I stopped using the Patreon app for podcasts with the big rewrite a while back where it became almost unusable and switched to Overcast instead.
Amazon Prime Video isn't targeting the US market anymore - they made a hard pivot to India [0][1][2], and as such are primarily investing in MX Player.
Back in 2018-19 because their founder Karan Bedi was smart and recognized he could leverage his past corporate experience in Big Media in India in order to make MX Player a streaming platform targeting India2 and India3, and thus build a scalable business.
Lots of companies can make decent apps. And IMO the Prime Video TV/Mobile and Amazon mobile apps are "decent" from a "they do what they're trying to do" standpoint and don't fail all the time.
But they don't really think about things from a "consumer who wants to watch something tonight" vs "shopper who we want to get money from" perspective. So the Prime Video app has been painful to navigate and use. Things like concepts of how people want to interact with TV shows - one top level entry with seasons in it, vs top-level entries per season, which took them forever to change - reflect quick and dirty shoveling of concepts over from how they'd sell box sets or such vs thinking about it from a user-first POV. Or how search will return a match for just about anything because they will happily sell it to you vs having as a default "show any free results first because I'm not looking to spend more right now."
That's a product/vision failure (or just mismatch with what you and I want) not an engineering/engineering culture thing.
This is really easy to answer, with some perspective from the inside, but mostly from public information:
- Amazon has 3 main business lines ("orgs"): Ecommerce, AWS and devices.
- Ecommerce and AWS are (now) cash cows. Devices bleeds money. TV falls into the devices organization.
- Devices was a Bezos bet. Current Amazon couldn't care less honestly.
- The devices organization is (today, after layoffs and people leaving in droves) essentially full of incompetent people, where all the leftovers of the other two orgs end up.
- It's people that was hired to build structure with the sole purpose of some higher-up promotion. They never served any other purpose, neither they have any particularly sophisticated skill.
amazon has mediocre quality talent that they grind to the bone. which worked when the company just needed raw execution. amazon has an operations culture, which was important for:
1. scaling retail
2. keeping the servers running at AWS

As anyone in software development can tell you, this does not compute. You cannot do things this way, and any experienced software engineer can tell you it doesn't work.
Besides, it's not how Amazon worked at all. Amazon is famous for having systematically verified ("mathematically proved") how it's core systems operated. Whereas, for example Google only did that in redesigns when the systems had already collapsed once or twice due to scale, not from early on. And even that is superior to how Microsoft or Oracle did it: they bought Google employees and had them design an iteration of what Google is running (yes, is running, not was running. Google redesigned it's core systems ... and then mostly didn't migrate. Borg was never replaced with Omega and the main large system that they migrated to is Spanner. Kubernetes isn't Borg. Kubernetes grew out of Borg's successor. Except Google never migrated away from Borg)
I'm sure Amazon had entire departments, much larger than core engineering, just like every other company, where it looked like everything was operationally focused. That doesn't mean core engineering doesn't exist, or does nothing.
Publishing a paper (in 2025) about formal verification is miles different than implementing it company wide. Anyone who has talked to an Amazonian SWE knows they’re not building their systems like this.
The Amazon way is to quickly grind something out, and build on as many layers of AWS abstractions as possible. They’re famous for the hustle and grind not the stellar engineering acumen of formal verification.
> A fully renewable energy system is probably always going to be more expensive per unit than a fossil fuel based one.
No probably not at all unless you mean in the short term. The fossil industry gets way way way more financial support. The externalities of fossils are costing us incredible amounts of money, health and lives and will do for many many decades if not centuries to come. Renewables are now cheaper than nearly anything despite decades of suppression by the fossil industry.
