Amazon Pharmacy sells name brand GLP-1s (Ozempic, Wegovy, Zepbound, etc) for $250-400/month without insurance.
jsjohnst··on Show HN: Run an 80B Qwen in 4.3 GB of RAM on a Mac, and a 35B on an iPhone
> This is why even their single core mobile chips in the budget line Neo

That’s a six core processor. It’s an A18 Pro in the Neo, same chip as on the Iphone 16 Pro

Since the majority shareholder(s) can decide to replace the board of directors, it’s not the board of directors who holds the (ultimate) power, it’s the majority shareholder(s).
jsjohnst··on What Claude Code chooses
> There are competing terms currently being decided on by the market at large: AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization)

It really annoys me the industry seems to be narrowing in on the two worse options rather than AIO.

jsjohnst··on Bitcoin tumbles below $70K, heavy losses in cryptocurrencies in last three weeks
> i'm actually not sure which is more risky: holding bitcoin or real estate

Both can have wild swings in valuation, but at the end of the day, you still hold something by owning real estate.

jsjohnst··on Apple rumored to be working on a smart home operating system version
As someone who has owned every single Apple Watch model/generation and love the hardware, I agree with GP on the terrible UX of the app grid.
jsjohnst··on Adding a feature because ChatGPT incorrectly thinks it exists
> it's also very much not, because it always sounds like it might be authoritative, but you could be reading something hallucinated

I keep hearing this repeated over and over as if it’s a unique problem for AI. This is DEFINITELY true of human generated content too.

jsjohnst··on Adding a feature because ChatGPT incorrectly thinks it exists
> The truth is, if there was no AI tech developed, we would not need to regulate it so that greed does not take over.

Same could be said for the Internet as we know it too. Literally replace AI with Internet above and it reads equally true. Some would argue (me included some days) we are worse off as a society ~30 years later. That’s also a legitimate case that can be made it was a huge benefit to society too. Will the same be said of AI in 2042?

jsjohnst··on OpenAI o3-pro
The level of hallucinations with o3 are no different than the level of hallucinations from most (all?) human sources in my experience. Yes, you definitely need to cross check, but yes, you need to do that for literally everything else, so it feels a bit redundant to keep preaching that as if it’s a failing of the model and not just an inherent property of all free sharing of information between two parties.
jsjohnst··on OpenAI o3-pro
> And nobody outside those companies knows how they work.

I think you meant to say:

And nobody knows how they work.

jsjohnst··on OpenAI o3-pro
The saying goes:

From 90% to 99% is a 10x reduction in error rate, but 99% to 99.999% is a 1000x decrease in error rates.

jsjohnst··on Google is burying the web alive
People (including me) said this for a long time about Yahoo! too. Kinda ironic they both merged and basically died together…

Yawho!?

jsjohnst··on Run LLMs on Apple Neural Engine (ANE)
> The bandwidth between macs isn't enough to do inference effectively.

While it’s certainly no where near the memory bandwidth, 80Gbps is on par with most high end, but still affordable, machine to machine connections. Then add on the fact you can have hundreds of gigabytes of shared ram on each machine.

jsjohnst··on xAI dev leaks API key for private SpaceX, Tesla LLMs
Boring as the noun, not adjective. Also, Tesla was named that before Musk was involved, so it’s not his humor involved in naming both. Nikola Tesla is known for a lot more than just Tesla coils.
jsjohnst··on Spain is about to face the challenge of a "black start"
From source article…

Actually, it’s not if you read the linked article. Try harder with your indignant reply next time to an entirely factual post. Sheesh!

Further, here’s a >one hundred megawatt generator installation (yes, used, but it’s always call for quote otherwise online) for a small fraction of the price of the EUV machine in case I need to further prove my point.

https://www.uspeglobal.com/listings/1705462-used-100-mw-2004...

There’s also multiple GE LMS100 generators installed in Texas and they each provide ~115MW of power. So not unprecedented for installation in the state either!

jsjohnst··on Spain is about to face the challenge of a "black start"
Yep, you did the simple math. 2MW generators are rather common place, they even come in portable (as in on a trailer) form.
jsjohnst··on Spain is about to face the challenge of a "black start"
Thanks for sharing the link! 1.3MW really isn’t that high of a load though. Thats a very straightforward load to be able to support via diesel generators. As an example, a typical large datacenter uses an order of magnitude more power, yet stays online following a grid outage.
jsjohnst··on Advanced Python Features
But the type signature of:

int -> int

Is wrong. At minimum it’s:

Optional[int] -> int

Because you provided a default value so clearly it’s not required to provide an input parameter. It’s also wrong to assume `0` is an int. There’s other valid types it could be. If the default was say `42`, I’d be pushing back a little less (outside of the Optional part), but this contrived example from GP had 0, which is ambiguous on what the inferred typing must be.

jsjohnst··on Advanced Python Features
> and, obviously, the inferred type (int -> int) is correct.

No it’s not. It’s Optional[int] -> int at minimum. There are other completely valid signatures beyond that too.

jsjohnst··on Advanced Python Features
1) the code you wrote isn’t Python.

2) inferring the type is int isn’t guaranteed to be correct in this case

jsjohnst··on Advanced Python Features
Because it shouldn’t in function arguments. The one defining the function should be responsible enough to know what input they want and actually properly type it. Assuming an int or number type here is wrong (it could be optional int for example).
jsjohnst··on Advanced Python Features
So you want strong typing, but then are to lazy to properly type your function definitions?
jsjohnst··on Zoom outage caused by accidental 'shutting down' of the zoom.us domain
Yet you still reply again! Guess you put zero value in your own advice, got it!

Yet you chose to reply-all-unsubscribe line noise further. Maybe take your own advice and move on bro.

Exactly!
jsjohnst··on Zoom outage caused by accidental 'shutting down' of the zoom.us domain
It actually didn’t help at all. Read the part quoted again, OP specifically indicated .us, not “root zone”. The registrar for .us (GoDaddy) is in fact the “root dns for .us”
