pj_mukh··on Pokémon Go Scans Trained the Navigation Tech for Military Drones
Pokémon Go being a military base opsec psyop is certainly a possibility. Just not what the original article is talking about.
pj_mukh··on Pokémon Go Scans Trained the Navigation Tech for Military Drones
Good thing we’re not selling this data to the Russians?
pj_mukh··on Pokémon Go Scans Trained the Navigation Tech for Military Drones
No the tech doesn’t work like that AFAIK. The most common use case is exactly localization (think “HD maps” for autonomous cars).

It almost 1-1 data correlation, n-phone Pokémon go scans of a location helping a drone locate itself in the same location in correlation with Maxar’s satellite data.

There maybe some hyper corner case uses. Maybe the billion scans in New York City help them generalize across different phone lenses characteristics, but phone and drone lenses are so different.

Would love to hear some specifics if I’m wrong here.

"The Middle-east" isn't a war zone. Even the parts of the middle-east that are, don't have any drone deployments. Lebanon maybe? Reports are thin.

Maxar is/was primarily a satellite data company, and to say Pokemon data would add any major value in any of today's active drone deployments with the level of Satellite coverage Maxar already has is a wide stretch.

Moreover, ground forces in the area would need pretty heavy jamming tech in place too for this kind of data to be useful. It's a sliver of a sliver of a sliver situation.

Which of those are active theaters of war? Pokemon Go wasn't that big in Iran or Lebanon and even there, there aren't any reports of significant drones deployed there.

The only place I can imagine is maybe Ukrainian drones in Russia. Still, not a tonne of data there to be useful (as compared to say Tokyo or New York).

pj_mukh··on Pokémon Go Scans Trained the Navigation Tech for Military Drones
As someone who works in this space, the headline is a bit of a stretch. The overlap in the locations of Pokemon Go Player data and any active Drone heavy theaters of war is a tiny sliver (or zero?).

The military contractor (Vantar/Maxar) in question basically admits so but just "reserves the right" to use the data which is the political battle line ala Claude and DoD.

This is mostly an ideological battle.

pj_mukh··on Ask HN: Why is the HN crowd so anti-AI?
"largest user of electricity"

Compared to what? More than all heavy industry? All residential usage for a given sector? Seems like a tall ask requiring some modeling.

pj_mukh··on Meta's ships facial recognition on smart glasses
But they are not "privacy invasion glasses", data isn't uploaded unless I explicitly tell it to. "Oh But he's definitely lieing", yes yes, I know, and the moment there is evidence for that, I can switch to other glasses and the Meta glasses are dead, so I'd love for him to try (unlike FB or Insta, there is no network effect here to hold me).

Either way I'm not a glasshole, I'm just a dad.

There is no point arguing about the value of photographs.

pj_mukh··on Ask HN: Why is the HN crowd so anti-AI?
You think we’ve built that many data centers next to coal fired power plants that the emissions have gotten anywhere close to the emissions of all the iron smelters and the billions of people that commute in gas cars?

We could triple the data centers since 2023 and run them all on coal or natural gas and then maybe they’d even show up as a significant slice on these pie charts.

Our bubbles have blinded us to the scale of the real problem.

pj_mukh··on Ask HN: Why is the HN crowd so anti-AI?
To OP's point, I am curious why a tech forward crowd would consider AI-training/inference anywhere close to a significant contributor of greenhouse gasses? Datacenters are like a tiny blip on emissions plots [1]

I think AI is a convenient foil to get people whipped up and out to vote, but I know HN is not the forum for that. The technical data clearly says that closed-loop water coolers don't use that much water and energy use is a function of a counties energy infrastructure choices not the existence of demand.

But instead we're going straight to destruction of planet as the exact verbiage, which seems way out of whack.

This would make you anti-OpenAI, not anti-AI given the explosion of local models. Two different ideas.
pj_mukh··on Meta's ships facial recognition on smart glasses
Fine in the crib, out in the open at a critical moment when your kid runs into your arms, screw image quality, you want that moment captured and with active kids there's about 2-3 of these moments every day. "the best camera is the one you have with you".

If I don't like something about my hot frog pot, I'll just switch to the Apple glasses when they come out [1] ¯\_(ツ)_/¯ . Zuck doesn't have much room to maneuver without shooting himself in the foot.

My larger point stands, not all who wear cameras deserve to be maligned.

pj_mukh··on India's surprise baby bust
Agreed with all of this but,

"cost of an apartment needs to be at-or-below the cost to build that apartment"

That's not true, its that the cost to build the apartment is far too high and the cost is totally passed on to a the public, thereby hovering up any disposable income that might go towards having a child.

There can be a profit margin, but the cost needs to be low.

pj_mukh··on Meta's ships facial recognition on smart glasses
Author has the word "dormant" in the headline and HN doesn't. Critical word. Let's not just support headlines when they confirm our biases.
pj_mukh··on Meta's ships facial recognition on smart glasses
This is screaming and downvoting into a void.

Parents have enough to carry around just because you don’t like a feature that is default off unless you ask for cloud analysis.

I don’t care what happens to Zuck, cancel him to all hell for all I care but maybe be a little more curious about why people use the tech they do past “people are stupid”.

pj_mukh··on Meta's ships facial recognition on smart glasses
How about Dad! I use them to film my toddler doing cute things without having to pull out the phone constantly and being more present. It'd be nice if people didn't call me names for doing so :)
pj_mukh··on Meta's ships facial recognition on smart glasses
Headline should be modded, these models aren't actively wired in anywhere. No idea why they'd be shipping these but the HN headline doesn't even match the blog headline.
pj_mukh··on Google Employees Internally Share Memes About How Its AI Sucks
I don't think "these are nuanced ways AI coding tools can be improved" is 404Media's play here.
pj_mukh··on Google employees internally share memes about how its AI sucks
Excel users complain about using Excel still [1]. They even make memes about it! Some of them work at Microsoft!

404media, please, take a deep breath. Your jobs are safe, your trauma is valid. Your corruption coverage is so good, but this 'employees make memes' editorial decision-making is exposing some deep insecurity I can't quite triangulate.

pj_mukh··on Mathematicians issue warning as AI rapidly gains ground
I'm not sure the similarities hold. The best comparison I've found is the construction unions in San Francisco. They frequently block housing that is factory built somewhere else in the Bay area even though that would make it possible to build tonnes of new housing in the city at a fraction of the cost.

"But Jobs" they scream and hijack the council to block new housing. I'm sorry folks, the point of housing isn't the jobs it creates, the point of housing is housing! New jobs ARE actually created, they are just higher leverage ones in the house factory.

Mathematicians are now facing the same... calculation (pun intended). And I think they are empowered to create a lot more leverage, and they shouldn't be afraid of it. A lot of them are catching on to this [1]

pj_mukh··on Mathematicians issue warning as AI rapidly gains ground
Ehh, I've had the opposite experience, with lots of writers and artists in my circle.

The markets that have replaced writers and artists with slop never valued them in the first place, and the markets that do will never replace them with AI, and I say this as an AI engineer.

Writing movies, writing theater, creating clearly original illustrations for various purposes, these are all tasks AI will never threaten, because there is just no point. And also, the market sizes for this kind of thing are a rounding error compared to say coding or back office automation which is incidentally the bulk of the token spend right now, confirming all this.

pj_mukh··on Martin Scorsese Is Embracing A.I.
Well said
pj_mukh··on Martin Scorsese Is Embracing A.I.
I am also curious whether a knee-jerk reaction to seeing the word A.I and assuming the worst will age well. It's not just you, this is media writ large now.

Martin Scorsese is using AI to build better pre-viz tools not create scenes and write scripts, but that detail is completely lost on the literati. The reactions roll in.

pj_mukh··on Trump signs downsized AI order after weeks of reversals
"The final text asks some AI companies to submit their powerful new models to a voluntary government review 30 days before releasing the products to the public, a pause that would give federal agencies some time to gauge what threats the products may pose to sensitive financial, national security and other computer systems."

How specifically does that review work? I want to give federal agency Opus 4.8 now, while 4.7 has been out for a while (leaving Mythos aside for now). They have 30 days to figure out whether it poses a threat.

How do you do that? Is there an eval for this and if there is why can't they just make it public? What is the agencies objective (but proprietary?) analysis here?

pj_mukh··on Can the stockmarket swallow Anthropic, SpaceX and OpenAI?
Okay before we set off the alarm though, can someone tell me What percentage of these index funds will be SPCX and TSLA?

Like if both these stocks become penny stocks what happens to the indices?

Isn’t the whole point that they are hedged across the whole market?

pj_mukh··on Meta launches Instagram, Facebook, and WhatsApp subscriptions
I mean, I'm paying about that for Google to hold onto all my personal memories via Photos, and all that I could actually use self-hosting for.

Meanwhile, FB has all my network that I can't recreate or self-host so yes, I would pay that.

pj_mukh··on Meta launches Instagram, Facebook, and WhatsApp subscriptions
This is exactly what I want Facebook for. The network has all this value baked in, but they'll have to look past its obsession with ads and slop.
pj_mukh··on Meta launches Instagram, Facebook, and WhatsApp subscriptions
Ehhh, what I'm paying for is FB/Insta's ability to bring everyone onto one platform and encourage them to post regularly. RSS, AOL Messenger etc, never were able to do that with any decent success.

That they went past that to just kill their own golden goose is what is now reversible via a payment plan. That might be their only saving grace on this now managed decline.

pj_mukh··on Meta launches Instagram, Facebook, and WhatsApp subscriptions
I would pay $49.99/mo for an unlimited plan that brings me only my friends' status updates (not their hyper-political likes and comments), just their life updates. Daily stories are great too. But JUST that, no influencers, no ads.

I realize Meta's data shows that our user revealed preferences tells them that we like all the dopamine hijacking garbage but that's like saying "Well users like drugs, so we gave them more". Let me pay you to give me just the vitamins, and none of the sugar.

pj_mukh··on The Structural Barriers to AI Lawyers
Literally an example of Jevons paradox in the original comment with data happening within the last 3 years.

America is the most litigious country known to man, it seems hyper implausible that as the cost of lawyers comes down with increased AI driven productivity, people won’t be reaching for their lawyers in infinitely more situations. Most legal issues involve no jail time.

Whether you believe the paradox will apply widely is purely a function of your algorithmic feed bubbles and the amount of AI panic on them. And that’s it.
