I have been working on a language learning app for myself, and I am using a textbook that I like as the basis for an Anki inspired “learning tree”. This is working pretty well because I can build progressions from the original table of contents.

Yes, generally if you get a decent progression from an LLM, I find it's copying directly from a source, like a book or course. Giving it a progression helps a lot.

A huge chunk of SoaceX value in their filing is attributed to their AI technology (aka Grok). I believe it’s 90% or more… Now, it seems they’re leasing the infrastructure required for Grok to scale to Anthropic and Google. I wonder how that math works…

But what is xAI? I thought that was the company that had the compute + Grok, the AI company? Since when does SpaceX (which I thought was a space company?) own AI-compute hardware and/or can do model hosting? Are all of Musks companies just one big thing now where the names no longer matter, or how is it supposed to work?

Edit: seems I'm just a bit behind: "xAI — now part of SpaceX ", seems really strange for a space company to buy an AI company, but I guess rather that, than the other way around.


I think some justify it as SpaceX plans to offer hosting in space, and then use Starlink to distribute it.

That's what the IPO salesman and pamphlet said anyway.

Can you provide a good example of something that is currently hosted in space and distributed via satellite?

GPS..

You believe that GPS is hosted on servers in space?

Technically, yes. Obviously stretches the normal definition of a server, but it is a computer controlled system "serving" a mostly digital signal.

https://www.baesystems.com/en-us/article/gps-iii-satellite-l...


What people are describing here is the colloquial definition of "server", being compute hosted in space. Not a broadcast signal that is interpreted on Earth.

Musk sold Twitter into xAI which he then sold into SpaceX as a financial engineering effort to lessen the impact of massive debts and cash burn. The IPO and some clever structuring is the final step in the process.

It's really just a debt transfer to make one company look good while the other is saddled with debt. Should be illegal

I.e., fraud.


Next up Tesla and SpaceX are going to merge and that will another round of synergies where Tesla and Vision AI (in FSD) and xAI.

Not really strange... if the goal is to go to mars, you probably need robots, those need intelligence -> ai. It fits pretty well, especially because you want to own all the core technologies as a company.

Wow…sounds like some kindergarten stuff

Why 4-5 companies instead of one then? I thought the goal of SpaceX was to get to Mars, why does xAI need to have that same goal? Or he didn't think xAI was suitable for that goal, then changed his mind so merged the companies?

You are overthinking this. The whole purpose of the SpaceX / xAI merger is for Musk to launder his failing companies to make them more palatable to the public. Not unlike the complex Mortgage Backed Securities of the GFC era which had a ton of low quality debt but yet were somehow assigned spotless credit ratings. Twitter is also being rolled up into SpaceX for the same reason.

I sure wish my company were failing the same way Musk’s allegedly are.

Personally I can go without owing money to Saudi royals.

Yeah, there are too many people happy to sacrifice principles for a buck...

The stated goal is to "go to mars", the real goal is to make money.

He sold his failing but hype business to his soon-to-IPO successful but kinda boring business.

It's a way of laundering the debt and dumping into investors as he pitted different indexes against each other to force his way into one of them, and have people's 401k buy into them. Its a ton of money.

I wouldn't be surprised if Tesla is bought into spaceX in the future.


He’s a drug addict and sociopath. Also has very thin skin (and hair) so he does stupid shit. Somehow we are all left holding the bag on his BS.

And Africa is left holding a larger bag of Ebola.

It has nothing to do with Grok, at least not the current iteration. SpaceX is the only company that can concievably launch large scale orbital compute.

I’m out of the loop, why is compute better /after/ being launched into space? Is the idea just to be co-located within the ISP to reduce round trip time to the LLMs?

There would be some benefits, assuming you could do it for a reasonable cost. For one, you have effectively uninterruptible power using solar panels in space. And it's free, too, once you have the hardware in place.

And you don't have to deal with any of the site selection stuff you have for terrestrial data centers. No NIMBYs. No politicians trying to extort bribes. No water problems.

In space there are no earthquakes, tornadoes, or floods.

I'm still skeptical. It's hard to believe it costs so much to build a data center on the ground that putting it into orbit is an economically viable alternative.


Yeah, launch costs alone make it infeasible, and power being "free" exacerbates the cost (gotta get all those panels up there). Cooling is also dramatically harder, plus shielding, and it makes repair/upgrade basically impossible.

I'm not going to assert that large scale space compute will never happen, but I feel confident saying it won't happen this decade or next.


When they get the kinks out of Starship, launch costs will be dramatically lower than we're used to thinking. They'll probably be using it to launch Starlink sats in earnest next year, so I don't think that would be the long leg.

I used to think heat would be a problem, too, but I've come around. It's a consideration, but it's doable. Remember we already have some pretty high power sats up there, so it's not something we haven't already been working around.

IMO the big cash drain will end up being maintenance, as in, you can't do it. If you have a box or a power supply fail on the ground you can swap it out. Anything in orbit would have to be replaced.


Things to think about: the russian satellites currently already in orbit and being tested to jam global GPS signals: https://youtu.be/tz23G_UXCGA?si=Jkg7hYnwER39-FXf (Veritasium). In all these sci-fi space datacentre scenarios, has anybody considered that astrolaw is in no way currently equipped to deal with datacenters in space? Neither are international relations.

> launch costs alone make it infeasible

Last time I did the math, launch costs were well balanced against permitting delays (mediated by interest rates). The break even rests almost entirely on radiator mass efficiency (which is, admittedly, a function of launch costs).

Like, if everyone’s terrestrial datacenter projects start getting blocked, and demand for AI continues, the price a rational buyer would pay for in-orbit compute could get ridiculous enough to break even on current kit. And current kit in launch vehicles, radiators and solar panels is advancing.

I don’t think the thesis is met yet. But it’s less ridiculous than I thought it was before I sat down with pen and paper.


Wouldn’t it be easier and cheaper simply to focus building your data centers in other poorer countries where your permits won’t be blocked? Why would the next most logical choice be “let’s put it in orbit”?

Grokipedia would be way better launched into space.

The risk is getting our planet annihilated if something stumbles upon it.

Yeah, but then it’s either an arduous manual review or incurring a bunch of token usage to review something that may be slop.

Hi! I'm Her and I have 6+years experience as a QA. I'm currently work as an Agile Delivery Lead and QA Lead for my clients based in AU, EU and UK. I've also worked with tech companies and startups spanning from different industries (Fintech, Banking, Mobile Apps, AI, Cloud) including IBM. I would like to bring my expertise to help you in your company provide quality products to your everyday users. Looking forward to working together!

Inbox Zero is filtering cold emails btw

Big dreamers, which is awesome, but they need a disciplined PM type team member to bring them down to Earth (ROI analysis on their roadmap).


> ROI analysis on their roadmap

I think we've developed software with "ROI" in mind for so long, that by now most people forgot how it was to use devices and interfaces that were made with passion and by taking your time, experimenting and finding the right way, rather than just rushing through stuff and optimizing everything for money.

I remember Flipper Zero had a ton of doubters early on too, myself included. I think I'm now willing to give them more slack to actually experiment and create something even more ambitious, as they successfully executed it the first time most doubted them.


I've worked in startups long enough to see many founders build without considering ROI.

It's not rare at all.

The reason you don't see those projects is because they don't make it very far. Big projects take a lot of effort and people and most people expect compensation for their effort. You can't compensate them without ROI.

As an open-source project they have some benefit of getting contributors to do some of the work. The hardware still needs ROI to exist. Making those custom parts requires up-front capital, which is going to need ROI to pay back.


For a preview of how this will go, take a look at this:

Here’s what’s crazy: by making this widely available to SMB, they will soon have enough training data to beat this benchmark —- in probably less than a year is my guess.


True! Between improving training data and figuring out how to provide better context to the LLM, there will be rapid improvement within a year


I tend to agree, but the gains will come at the expense of the early adopters. Then again, this has been the case in so many industries throughout history.


Wish they would update it with the newest models. Probably still fails but would be interesting to see the mistakes getting fewer.


Overkill in what way exactly? The LOC of the project shouldn't have any bearing on most people's usage of the project. SQLite is one of the well tested and mature projects in the world. What exactly would motivate someone to use PeakSlab instead? What problem are you solving?


Read the comment. He's using it in WASM form and doesn't want users to have to download 1.2MB of SQLite every time they visit the page.


Client caches are a thing, so this is most relevant for cold-start customers. In that case PeakSlab’s download size is an advantage.

Fwiw LocalStorage is a SQLite db on most browsers, with a kv api. It’s be interesting to have the actual API available.


Even on warm start PeakSlab is twice as fast. It's not just download size, it's execution speed, zero copy, database decompression, etc.

That's why PeakSlab is written in c, because what's faster than casting the whole database to a struct? ;-P


I think web sqlite was originally an (experimental) thing


I'm solving a simpler problem. Just making cross platform dictionary progressive web apps with indexes and full text search and HTML tags and uppercase letters inserted back into the text on render so they don't interfere with search.

SQLite is 1.2mb in combined wasm and JavaScript and not really designed for my use case, so I would have to add all the things i need anyway like compression and HTML tag insertion. For my use case which is just for pwas SQLite takes too long to load and the files are too big and the search isn't tailored. So I made something else in 38kb instead


Got it, thanks.


For someone complaining about slop, I found this unreadable.


A job from hell is a bad job by definition.


We can thank RFK for anti-vaccine leadership leading to changes to the childhood vaccine schedule which make preventable diseases harder to stop. You can celebrate more cures all you want, but as most people know, prevention is the best medicine, and the guy is lukewarm on one of our best defenses when it comes to keeping kids safe (vaccines).

And, let's not forget that RFK said: “every Black kid is now, just as a standard, put on adderall, [selective serotonin reuptake inhibitors], benzos, which are known to induce violence. And those kids are going to have a chance to go somewhere and get re-parented, to live in a community where there’ll be no cell phones, no screens, you’ll actually have to talk to people."

So yeah, according to RFK, every black kid in America deserves "re-parenting". He should resign today.
