pj_mukh··on The glass backbone: Why the Army's logistics will break in the next war
Woah cool! Any write up’s on this?
pj_mukh··on Mistral's Robostral Navigate: a state of the art robotics navigation model
Would be extremely interesting to build an "Exploration" node of sorts. Solve a sort of Semantic SLAM problem as you go.

So if you can give it an instruction to "Find the elevator on this floor", could it walk around and build a map as it goes so it starts doing what a human would do to find the elevator.

As of now, the way these navigation models are setup, it assumes the instruction writer was intimately aware of useful visual navigational landmarks to give, which is not realistic for most use cases.

pj_mukh··on AI Data Centers Use More Water Than Most Tech Giants Report
tl;dr: Because the power plants they rent power from, and have very little control over, use water too

Is that water cleaned and put back in the environment?

Can the municipalities use the tax cash influx to clean up their power sources?

Not answered or considered which is weird for an org as storied as WSJ.

The bottom line is Heartland re-industrialization will use resources and look different from previous industries.

Can we keep the political focus on the oligcharcal control over our government instead of making something as dry as data centers some kind of new frontline on the Omni-cause

pj_mukh··on Show HN: Claudoro, Pomodoro timer embedded in the Claude Code statusline
Love that it follows you from terminal to terminal, super useful.

Though, if you're following Cal Newport-ian rules, watching over multiple agents doing their work is no longer a 25 minute "deep work" Pomodoro, and god knows Newport has been complaining about it [1]

pj_mukh··on Weave Robotics launches Isaac 1, a $7,999 home robot with Fall 2026 deliveries
Except this is a daily/nightly service?

Atleast in my home, it’s the daily cleanup that’s operationally grating with babies and toddlers. The weekly/monthly deep cleans are downright fun.

pj_mukh··on Weave Robotics launches Isaac 1, a $7,999 home robot with Fall 2026 deliveries
Yea I would hope for sustainable teleop unit economics and then VC money for autonomy.

But I don’t need high percentage autonomy out of the box was my point.

pj_mukh··on Weave Robotics launches Isaac 1, a $7,999 home robot with Fall 2026 deliveries
Do I care? The job gets done and I don’t have to bother with letting someone physically into my home.

As a parent this seems godsent if it works as advertised just for its overnight reset.

Now if they can’t make the autonomy work to maintain the economics then I’d need an exit clause but other than that, have at it boss.

pj_mukh··on Mag 7 starting to underperform [pdf]
"I love how they show OpenRouter’s graph of token usage as if it speaks for usage across the board."

I'm not sure what was said during what looks like a deck of a presentation? I'm hoping it wasn't this, because that's an obvious misfire.

pj_mukh··on Congress Clears Housing Bill, Cementing a Rare Bipartisan Feat
The easiest way to get a higher valuation for your house is to sell to an apartment builder. I realize there are loads of cultural hangups around doing that (the driving force behind NIMBY-ism), but the mathematical truth is that there is a win-win solution here if "Everyone wan'ts the house they sell to be worth more" is the only problem.
pj_mukh··on Congress Clears Housing Bill, Cementing a Rare Bipartisan Feat
We all love the bipartisanship, but this is probably too little too late.

Partly because the federal governments leverage on local politics is very little but majorly because currently the interest rate and the labor/material costs is just too high especially on the coasts and none of that is regulatory burden. The Atlantic had a great breakdown [1].

Congress and/or state governments should work on a preferable interest rates for construction loans scheme and engineers need to bust through Moravecs paradox to get some productivity boosts in construction going, everything else is window dressing.

The ball has moved!

pj_mukh··on Good results fine tuning a local LLM like Qwen 3:0.6B to categorize questions
because you have a different vector store for each categorization?

What if the question crosses categories?

pj_mukh··on Good results fine tuning a local LLM like Qwen 3:0.6B to categorize questions
“As an example, the question “When did we replace our pool pump?” will be mapped to a category called “pool” before querying the Index database.”

Cool write up! Really appreciate it but incidentally how does this categorization help you get better retrieval results?

pj_mukh··on Smashing the NIMBYs created modern capitalism
Yea exactly, OP’s argument is the same as

“if you want the government to pay more taxes you should just personally write a bigger check during tax time”

The underlying optimal game theoretic action is obvious (and therefore common), the problem are the laws that require you to respect the neighbors.

This is why state-wide anti-NIMBY laws can get passed, everyone thinks it won’t come for them so they let it pass. Let’s pass more of those and make em stronger.

pj_mukh··on Wages in America Are Too Low for the 30% Rule to Work for Renters Anymore
Yea,

"We currently have 10 houses renting at $2500 for 15 people who have $2000 to spend on rent. WHAT IF, we gave those 15 people $2500 instead. Housing crisis solved?"

-This article...basically.

pj_mukh··on The UK's Teen Social Media Ban Is Political Theater, Not Child Safety Policy
Barring any real causal studies, I’ll lean on the experience of teachers and school boards [1].

Note if the article called for instituting a school board ban instead of a country-wide ban, I’d support it. But the article is fundamentally questioning the existence of the problem which was a silly over-reaction.

pj_mukh··on The UK's Teen Social Media Ban Is Political Theater, Not Child Safety Policy
The problem is, a classroom full of TikTok zombies doesn’t fit into the 20% more work vs. 80% more work dichotomy. It’s simply spending 40 hours a week talking to an (almost literal) wall.

It’s money sure, and some teachers who don’t care can keep going. But most who do, would be happy to switch to a place where they can make a difference.

This is all a separate conversation to school resources is my point.

pj_mukh··on The UK's Teen Social Media Ban Is Political Theater, Not Child Safety Policy
The original article doesn’t care to explore the difference, it doesn’t even acknowledge there is a problem.

If the article was “instead of a national ban, we should look at school-wide ban”, I would be sympathetic.

FWIW, American states are doing exactly this[1], people still complain

pj_mukh··on The UK's Teen Social Media Ban Is Political Theater, Not Child Safety Policy
Quoted in your article:

“Later this year a ban on mobiles in schools – even for educational use – comes into force.”

It’s obvious to most that taking away the laptop while leaving the TikTok will not have the intended effect.

pj_mukh··on The UK's Teen Social Media Ban Is Political Theater, Not Child Safety Policy
This is not about resources anymore.

What’s especially interesting is that a lot of teachers take a paycut [1] to go teach in private school partly because the kids are better adjusted, rich kids have more comprehensive childcare and don’t need to rely on screens/social media for the gaps in parenting.

For a taste of all these details, go on r/Teachers

pj_mukh··on The UK's Teen Social Media Ban Is Political Theater, Not Child Safety Policy
Article mostly cites self-reported studies ie the kids think that the kids are doing alright, which is a different statement from the kids are actually doing alright.

Most teachers seeing generational changes are raising five alarm fires around how badly the kids are doing. Actually testing kids is showing a startling reverse Flynn effect [1]. I’m curious what the author has in terms of actual evidence here?

pj_mukh··on Peopleless economy? Not technically impossible
Whenever I see headlines like this I have to tap the glass and point to this class article [1].

tl;dr: The most likely scenario is that AI affects us at the scale of the internet. Revolutionary, but nothing that fundamentally gets rid of labor economics (like this article posits).

pj_mukh··on CrankGPT
"Tech companies have quietly abandoned their climate pledges to build gas-burning power plants that feed your favorite AI."

What I love is this quote is super-imposed with a background image that has gas-burning smokestacks but also nuclear cooling towers in the same field.

This is a bit representational of this particular line of protest against AI - just super confused about it all and thrashing out.

Green energy has been (technologically) solved, but instead we want to go back to manual labor as a source of power? Hilarious.

pj_mukh··on The first game engine for robotics
Is there a good Unreal + Physics simulator OOB now that people can try?

I guess Isaac Sim is king?

pj_mukh··on How to earn a billion dollars
"Many cities have enough money to buy or construct social housing for anyone who wants"

This is patently untrue. Especially for superstar cities that people actually want to live in precisely because the cost of housing is too large.

"outsized political influence of existing homeowners; "

Otherwise known as NIMBY's not Airbnb's.

pj_mukh··on The first game engine for robotics
Wondering if it would be better to abstract Vulcan away by Unreal, get even better photo-real quality.

I guess the better question is how much does photo-realism quality matter for this kind of sim2real work? A lot I would wager.

pj_mukh··on How to earn a billion dollars
Or you can get to know me! Visiting from another city. New friends are good! <2% of most cities are Airbnb's, they by no means preclude having permanent neighbors.

And parties are banned on the platform, I know because I had enforcement against me for even having my sister's family over when Airbnb's were legal in New York City.

pj_mukh··on How to earn a billion dollars
It's not a conspiracy, they aren't meeting in smoke-filled rooms. It's just a systemic problem, a classic tragedy of the commons. An individual neighborhood move to protect an old church is noble and courageous, but do that all across society and you basically have a construction standstill that is difficult to visualize and effectively regulate against. So yes, it is a complex problem, but the cause is singular, and because of its multi-dimensionality, I find these causes to be far more insidious than "profit-bad" problems.

I think the second more prominent cause maybe costs, labor, material, interest rates etc. But Airbnb's are far..farrr down the list so as to be completely irrelevant, as the natural experiment in New York has proven out.

pj_mukh··on How to earn a billion dollars
>I don't know about home ownership - but not having random strangers I

I mean, this is just garden variety NIMBY-ism. Having a quiet farmhouse in the middle of midtown would also be a definite improvement just for you, but you're choosing to live in the most economically productive center in the world, and there are practical tradeoffs for that.

pj_mukh··on How to earn a billion dollars
No because Airbnb bans are basically political bike shedding. Yell at the guys sprinkling oil on the fire because taking on the NIMBY's flooding the region with oil is too difficult.

"Multiple causes" is just mealy-mouthed pussy-footing, there is one big cause and then a bunch of other distractions as the numbers now prove.

pj_mukh··on How to earn a billion dollars
"To have illegal hotels that then help keep a generation out of home ownership?"

To solve this, New York City (basically) banned Airbnb's and home ownership is now famously more accessible in the City? I am not even asking for home ownership + rentals to be solved, I am asking whether it got even slightly better because of this ban?

Meanwhile, I can't visit my sister because the regulation cartel..I mean Hotel Lobby has spiked pricing to the high heavens.

Maaaybe we need to revisit some of these easy assumptions on your list?
