"The surface of the Earth is the shore of the cosmic ocean. On this shore, we've learned most of what we know. Recently, we've waded a little way out, maybe ankle-deep, and the water seems inviting. Some part of our being knows this is where we came from. We long to return, and we can, because the cosmos is also within us. We're made of star stuff. We are a way for the cosmos to know itself." -- Carl Sagan

z2··on AI companies in race to demonstrate their model most threatening to humanity
Here's a relevant article by the Onion from the summer of 2022, before ChatGPT. https://theonion.com/ceos-warn-against-the-dangers-of-artifi...
z2··on Fixing the Portobello Police Station Clock
I've embraced postmodernism and my latest hobby is using LLMs to connect ESP32s to random stuff in my house, so I can unironically WiFi-enable everything from my toaster oven to my 1950s 4-chime doorbell.
z2··on Bonsai 2 27B: Near-Lossless Compression in a 9x Smaller Footprint
I'd love to see a Bonsai model start with a 100B+ parameter model and get that down to <30 GB. But maybe at that point we call it Topiary?
z2··on Why Does the Universe Expand?
I've always thought it would be interesting if the universe also operated on the principles of lazy evaluation, and the deeper you point the telescope, the more is rendered.

That or that it's all a fractal!

z2··on Mexican student creates an acoustic fire extinguisher to put out fire in seconds
Granted, as another post noted: https://patents.google.com/patent/US10569115B2/en
z2··on OpenAI Agents API
After being burned by the rug-pull of OpenAI retiring the Assistants API in favor of Responses last year, I swore off using heavily stateful APIs for language model access. I could be totally wrong, but at this point I'm more willing to use a proprietary harness headless than to abstract it into an API.
z2··on Show HN: Algo-Trading-Skills - 501 agent skills for trading infrastructure
My question is how many tokens were used to generate this and the 20,291 test cases, and could the electricity have been better spent baking a few hundred pizzas.
z2··on GPS glitched across the US by as much as 33 feet
Whoops I don't know how I missed that in your links!

The weird part to me is that Glonass was not approved either, yet it's as openly as allowed as Galileo that went through a tedious FCC approval process that was invented later. Grandfathered or not, we're clearly not in a worse place using Russian tech for the last 15 years.

z2··on GPS glitched across the US by as much as 33 feet
It decreases dependency on GPS and thus it decreases risk because if there's an attack on a GPS system by an adversary, it's likely that they will not be attacking their own system at the same time. I'd rather have my enemy's open source, perfectly functional clock in my back pocket than be without the time. Enjoying that the competing clock has a sub second display is optional.
z2··on GPS glitched across the US by as much as 33 feet
For resiliency reasons alone, it's been proposed to allow (stop software-disabling) BeiDou in the US, but the last time this was brought up, the administration ran out of time. It's a shame, because when there is precise coverage, it enables things like lane-level city navigation.

z2··on Nvidia agrees to acquire Hugging Face for $13B
Everyone's got a noble goal until they get a buyout offer promising to make them a billionaire

Edit: Just discovered via this post that hn posts, like the exchanges, filter out emoji

z2··on Kusama Yayoi has died
Highly recommend watching her speak, for instance in the below interview. I've found her to be very eloquent and expressive verbally too.

z2··on Anthropic's best AI model struggles to attract users as cheaper tools thrive
The analogy is apt because I feel this is exactly what keeps Anthropic and OpenAI's owners up at night -- becoming the utility company the People want them to be. Ironically their behavior may accelerate their fears. And yes, the so-called safety features are ridiculously invasive and the worst is agreeing to have surveillance cameras installed in every room that occasionally detect any attempt to grow plants with LED strips as a pot farm. After a false alarm of almost having my ChatGPT account terminated for cybersecurity abuse and appeals auto-denied twice (I did nothing even close to hacking), I have started doing everything I can to decrease switching costs and thus the bargaining power of the suppliers and I'm doing the same for my company.
z2··on New Casio F-B100W – Upgrade to the iconic F-91W after 40 years
I had the same thought--speculating, perhaps it's like you say and we'll see a disclosure somewhere that it's "Up to 2 years, with 1 weekly Bluetooth pairing, 1 second of backlight use per day, no step counter."

Though, the CR2016 is a pretty big battery vs typical watch batteries, and in some other Casio watches are used as 10-year batteries.

z2··on How does IKEA come up with names for its products?
Yeah, given they sell to every continent, I find it utterly impossible they truly tested this with each of the dozens to hundreds of languages their customers speak.
z2··on Cerebras CS-4
For now you can rig an adapter to your nearest DC EV charging station, but make sure it's near a body of water for the cooling.
z2··on Memory prices climb 500% in 12 months
And that's the really fun part of all this, that weak substitutes will also become more expensive. But on the bright side, I've got dozens of sticks of DDR3 RAM that I'm hoarding like Pokémon cards. Any day now, we'll get desperate enough to start using them again!
z2··on Mushroom behind 'tiny people' hallucinations identified
I think this first example is spot on. Though a sibling comment's Wikipedia link doesn't mention it, there is a diminutive or hypocorism use that I feel is best translated into English with the -y or -ie suffix.

And it kind of works for verbs too: 看看 [take a] looky

z2··on World Train Map – 1247 train routes around the world
I was about to say the same thing, having just coincidentally been looking at China's map https://en.wikipedia.org/wiki/Rail_transport_in_China#/media...
z2··on Should you wash your solar panels?
Given the angle of a panel should match its latitude and average sun angle, the panels might generate noticeably more by being pitched steeper at over 30 degrees. Eyeballing this, it appears closer to 25 degrees right now which doesn't even make sense for the summer sun in the UK. I could be wrong as it also appears these are on a slope!
z2··on Medici family mystery may be solved after more than 400 years
Yeah, we're talking hundreds to thousands of mosquitoes per 1/10 of an acre, many or most of which are actually not actively flying, right? I can only see this working for dragonflies where the mosquito is the energy source.
z2··on SpaceX bond worth 10% less than issue price – heading for junk bond status
Putting one's money where their mouth is in expressing that a company's stock appears overvalued is very low on my list of "things that exploit the proletariat."
z2··on Apple's new SpeechAnalyzer API, benchmarked against Whisper and its predecessor
I don’t know how Apple divides computation between the GPU and the Neural Engine, but one major benefit, especially for real-time transcription on laptops, is the improved power and thermal efficiency. I noticed better accuracy after switching my app to SpeechAnalyzer, and I suspect part of that improvement for me came from the microphone no longer having to compete with jet-engine fan noise.
z2··on ChatGPT Work
So will the new ChatGPT (Codex) refuse to respond at all after the 5-hour quota or weekly quota is used up? It always felt that 5.5 on the website was a lot more generous than the Codex version. And at least the website/old app could downgrade you to a lower model if you used up that quota.
z2··on China sentences official to death for taking $325M in bribes
I don't think this makes any sense, what you argue would imply that the external historians would say that Japanese history starts in 1947 or that French history starts in 1958, but I'm not sure if they nor people of those countries would agree with that.

The point is, there's a lot more to history than political organization. A continuous culture and language is a big part of why civilizations extend far beyond the current governing regime.

z2··on Apple raises prices of MacBooks, iPads
Same here, reserved a 48GB M5 Pro shortly after seeing the news, and now I see the same retailer raised the price by over $1000. If they honor the sale, then this will be the most short term value I've gotten out of an HN submission ever.
z2··on Show HN: Ideate a trading strategy with an Ex-Citadel Trader
Will the coming wave of AI-assisted amateur traders make markets more efficient especially as they are more motivated to seek value in less liquid places, or will it be like sending children with candy into the playground that the bullies can easily steal? Or is it both? Asking for a friend.
z2··on Japanese symbols that speak without words
Both have pretty enjoyable design language. The US signs follow colors, red for prohibition, white for rules, yellow for hazards, green for directional and blue for service. For Europe or the Vienna convention that much of the world uses, in respective order it's red for prohibition, circles for rules, triangle for hazards.
z2··on Job application asked for my SAT scores
And the meaning of the score changes over the years based on the test itself changing. Same goes for the company's GPA requirements where there have clearly been shifts across schools on the amount of grade inflation allowed or even encouraged.

As an aside, I'm not sure if I or the College Board can prove my score at this point.

z2··on How many of the 170k English words do you know?
In particular, I got a bunch of guesses correct because there's a pattern that several options are often related to each other, and either only one is different, (e.g., "Do good", "Do bad", "Be evil") -- in which case the answer is obvious -- or at least there's a contrasting pair which narrows it down to a 50% chance.
