I want to believe this is a glitch but then again with Tim Cook (and Apple) has shown many times that he'll do whatever it takes for being in the good graces of the administration.

> Five months ago, we rebuilt our warehouse [1] on DuckDB instead of ClickHouse.

Why did they write this post if they had not even allowed things to settle. It sounds like someone wanted to claim victory (and promo?)

https://posthog.com/blog/why-we-rebuilt-our-data-warehouse


The intro to that post is so bad: "PostHog's original data warehouse had a single goal: delay the moment a company needs to hire their first data engineer."

It is not to serve high quality and timely data to make good decisions, is to avoid hiring a specific role, lol. So bad.


Ironically a good data engineer should probably let them avoid needing 3 different data warehouse systems within a year.

Engineers like to experiment and we get the benefit of learning from their experiences. Not sure why you’re upset.

Maybe it's the "me first" mindset you're bringing to engineering?

no ones upset, I think given the quality of technical write ups we see on HN with very detailed analysis that this article felt like a faux tech article to promote a product? But it kind of is a self own as it just looks like they didn't do due diligence with their tech choices.

> Engineers like to experiment

The job of management is to help manage that. Typically, the desire to experiment is constrained to lab environments and so on. Experimenting on your actual users carries a lot of risks - to product stability, customer relations, market perception, etc.


I mean, mostly it just comes off as egregious self-indulgence to try one thing and then jump to "we built the solution ourselves!" when the problem is not novel at all. These things are just tiresome.

This sounds more like a 5 month POC that the engineer should have been able to prove sooner that DucksDB didn’t fit the use case.

Author here. We went past the POC stage to actually make real customer workloads work, which we did. Probably yes, we spent too much time not rethinking our approach but sunken cost fallacy so that's why.

Author here. I admit I kinda left out the context which is important here. We did not replace Clickhouse. Instead we want to move our warehouse product from Clickhouse to another stack which suits the long modeling jobs and multi-tenancy better. We learned through all our early design partners running huge workloads what we need to change.

As much as I'd love to claim victory, we are not there yet :)


This is the same company with intentionally annoying full-wrap bus ads on Muni. They are trying to capture mindshare.

Posthog is a relatively small company, and they have victory-claiming people already.

NGMI


Nothing about Apple has changed. They make incredible hardware, and their CPUs are really good. Just that Apple enthusiasts put them on a pedestal thinking they are one of a kind.

There were just another company, doing a lot of good things, and also doing a lot of bad things. Most people were willingly ignoring the bad parts until now.


How is this any different than terra, sol etc or leopard, yosemite etc, or model x, y, 3, s ..

Don't know about the leopard and model x, but at least in the case of OpenAI luna > Terra > Sol > Astra is a pretty obvious size progression.

But I come from a latin language background, so maybe I'm a bit biased there.


At the risk of taking a geocentric position, my gut feel is Terra -> Luna -> Sol -> Astra. Sorting algorithm is distance from observer.

Size wise Astra is not categorically bigger than Sol, both in absolute terms and the observed size.


Astra is latin for "stars", so basically the Galaxy (or Universe as a whole) which is categorically bigger than Sol, the sun, a single star.

The naming makes perfect sense to me, the sorting algorithm is size, both for the names and for the models themselves. Smaller things represent smaller models, and vice versa.


> the Galaxy (or Universe as a whole) which is categorically bigger than Sol, the sun, a single star.

I would need to be a complete moron to argue with this. Humor me, however. My Latin skills end at remembering "Romani Ite Domum" and English is not my first language.

My layman reading of the names: there is one Terra, one Luna and one Sol => "Astra" is singular.

Now that I googled it, I understand that "Astra" literally means the "Stars" category. I would not have thought that they called a single star "Astrum". On the other hand, I am not sure if it means "Galaxy" in modern sense, but we're entering Roman Astronomy territory, where I am even less knowledgeable than in the language.

Sol is a star, so having a dedicated Stars category on the naming scale makes less sense. Treating Astra as Stars set without Sol, the "distance from observer" argument still kind of makes sense.


> My layman reading of the names: there is one Terra, one Luna and one Sol => "Astra" is singular.

That is incorrect. "Astra" is Latin for "stars" (plural). The singular would be "astrum".


Ad Astra. To the stars.

Yeah, this was my initial thought as well... I guess they didn't ask anyone before choosing the new naming scheme. But that isn't particularly surprising.

It doesn't help that the moon and sun have roughly the same apparent size in the sky

Size is by far the most obvious one, at least for me.

Why on earth (no pun intended) would anyone do this?

Good God, what has happened to people here? You literally wrote that Luna is greater than Terra, Terra is greater than Sol and so on.

Maybe just read this like an arrow?

    Luna  = Moon
    Terra = Earth
    Sol   = Sun
    Astra = Galaxy

I didnt know this but apparently Astra is the plural of astrum (latin for star).

Cannot wait for Universe and Multiverse levels.

Or perhaps they'll release Supernova, then Singularity to market their ASI model.

In the multiverse version, the model isn’t any smarter, but it’s evil.

Only if it has a goatee, which is how we know Robert Downey Jr's Iron Man and Benedict Cumberbatch's Doctor Strange were only the heroes of their own narratives, and nobody else's.

“Let there be light.”

Astra means star, like the Sun

"Stars", if I'm being pedantic.

Not pedantic, the plural is the point. More than one star (Sol).

I went by their illustration of GPT 6 Astra that looks like a spiral galaxy[1].

[1]: https://openai.com/index/gpt-6-astra/


Astra > Sol > Terra > Luna seems clear enough to me

Leopard (10.5) and Yosemite (10.10) both came with clear version numbers

Model X and Model Y are siblings which do not have a clear hierarchical relationship

Gemini 4 Carbon and Gemini 4 Argon are rather difficult for me to tell at a glance


Confusingly, Carbon is another model in the same size class as Argon. Every other lab would have just called it Gemini 4.1 Argon.

AFAIK they are all (Barium, Argon, Carbon) different checkpoints of the same (ongoing) training run

Ideally, Google would have run with:

Argon > Neon > Helium

That would have been the noble thing to do.


Or the other way around! Radon would have been an awesome name.

Luna/Terra/Sol/Astra make perfect sense, it indicates model tier/size with larger celestial body representing larger model.

Same for Anthropic, consistent model tier naming reused across model generations.

Those are just like i3/i5/i7 or M-series Pro/Max/Ultra.

But Carbon seems to be full replacement of Argon announced two weeks ago, they're same price. So Argon doesn't mean anything, they just picked random element.


Both openai and anthropic names feel much more confusing than cpu names to me.

They'd be fine except every named model has multiple numbered versions, with no consistent relatioship between cost or capability corresponding to the version numbers going up or down.


Could it be an alphabetic system like Ubuntu's?

I thought the obvious next one would have been Boron then

FYI, Model S, 3, X, Y is an acronym for S E X Y.

Lol feeling so dumb rn. How have I not noticed that before and how such an unserious guy is the richest man on earth?

The only hindrance for him was that Ford still held an automotive category trademark for Model E, hence Tesla had to go with Model 3.

He is extremely unserious. Did you miss the part where he cheated at Diablo to try to seem to be some kind of dedicated gamer? Or, y'know, the whole Cybertruck? Or the "pedo guy" comment after his harebrained submersible idea went nowhere and a regular diver saved a bunch of Thai kids?

He's always been deeply unserious.


And DOGE

The pedo-guy comment though I think was him being serious, unfortunately.


And all the 420/69 references. And doing "let that sink in" as a live-action bit.

Just that Z was on the market before 3 was, right?

do you mean X?

Fun fact. Model 3, was initially planned as Model E, but ford held rights to "Model E". They were also planning to release it earlier i guess but it got delayed. Took them some time to cut the cost


Oh my god...I just realized SpaceX = Space Sex?

Nah, Elon is well reported to have been crazy about "X.com" since ~2000 and thus it makes sense it got incorporated into SpaceX name

The original was that’s too lame for BitchX.doc and then it got replaced by all sorts of other things. Was an IRC meme before memes were a thing.

Would it have been so hard to call it Gemini 4.1 or 4.5?

Then how would you compete with Anthropic and OAI with such boring names?

Is this was xai isn’t winning because they still use numbers for grok releases?

Do both like OAI and Anthropic do.

terra/sol or opus/haiku give an indication of size (the sun is bigger than the earth, opus is larger than a haiku). Carbon is smaller than argon (periodic table speaking), so that's no longer a helpful way of thinking about the model sizes...

Dont companies always talk in private? Like, Apple having a business meeting with Meta is not nefarious nor out of the ordinary. Companies coordinate on things all the time. Why is that surprising to you?

AAI styles itself as being independent of the companies it's evaluating.

Isnt it about risk?

Just because you saw your friend move to a new country for a job doesnt mean you will make the same choices, even if you are similarly qualified.


I think the confusion is lot of Apple enthusiasts drank the kool-aid the company served them saying touch screen is "yuck". And now they have a touch screen, it takes a while to re-orient themselves.

We saw this with foldables. It was a bad idea, but when Apple did it, it was a great idea all of a sudden.

And if you rewind a while back, you'll see "large phones are bad because one handed use .. blah blah" and then Pro Max.


I really really love uv but this uv-ty post seems "shipping the org chart"?

They could have just said uv now has type chancing capabilities (or whatever it is ..) ty afaik isn't a super popular brand so the post makes people first understand what ty is ..


Why do they need to even do that? They already know the link from the email body. This is some urban myth.

If it is for click tracking there are far efficient ways to do that.


You do realize all companies, including the most "moral" companies advertise - like Apple?
