Yes, plus, all these meta-studies always seemed to ignore the reasons for the demand shock.

"It's not the permits, it's the demand shock" (the last image in the blog post). The "demand shock", was the economy growing...quickly. And that statement is left hanging in the air like we're supposed to do something about it.

The economic growth is a good thing, we should have a housing system that reacts to it like surge pricing but instead we get a lot of hand-wringing then rezoning 5-10 years too late, so instead of temporary surge pricing, we get permanent ultra-heavy-high-surge pricing.

Woah cool! Any write up’s on this?

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.

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

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]

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.

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.

11 days agodiscuss

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.

"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.

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.

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!

because you have a different vector store for each categorization?

What if the question crosses categories?

“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?

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.

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.

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.

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.

26 days agodiscuss

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

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.

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
