pj_mukh··on Subway crime plummets as ridership jumps significantly in congestion pricing era
The technicalities of what does or doesn't convey a crime is wholly irrelevant to the voting public. Voting being both at the ballot box, and w/ their dollars towards the MTA.

It's a signal we aren't measuring and it's massively affecting rider behavior.

pj_mukh··on PlayAI's new Dialog model achieves 3:1 preference in human evals
To the founders: Would love to share my audio files with my team before we commit to a payment plan. Is there anyway to share audio files I've generated?

Our whole team is on Elevenlabs and a switch is significant work, but I think the results are worth it! Super awesome work!

pj_mukh··on Andrej Karpathy: Deep Dive into LLMs Like ChatGPT [video]
"Something I could for example give to my parents,"

Not for nothing, Andrej's parents maybe different from mine, but I definitely can't send this to my parents.

I wish we could be more specific about these labels. Whats a “complaint”?

Is that a disagreement over an empty seat or a woman getting burned to death. Are those in the same bucket?

Yes, “mentally ill man made me feel uncomfortable” is definitely underreported, but it’s hard to believe murders and assaults are underreported. And if those are down, this is a huge win.

pj_mukh··on America desperately needs more air traffic controllers
Can I just admit how insane it feels that in the Year of our Lord Automation 2025, air safety basically amounts to:

"Yo watch out for that big plane on your left" and then hope for the best.

pj_mukh··on "A computer can never be held accountable"
Technology has nothing to do with this.

Before technology there was "McKinsey told me to do this". Abrogation of liability is a tale as old as time.

pj_mukh··on Cali's AG Tells AI Companies Almost Everything They're Doing Might Be Illegal
We're splitting hairs here. Open up the ChatGPT window and have it do something nefarious without you touching the keyboard. Then these AG actions would make sense.
pj_mukh··on Cali's AG Tells AI Companies Almost Everything They're Doing Might Be Illegal
You can create all kinds of nefarious artworks that are hurtful to protected classes using a pencil, or adobe creative suite or what have you. Doesn't mean those things are illegal.

Charge the creator not the tool. This seemed immediately obvious to me, but apparently not to most layman (including the California AG, apparently).

pj_mukh··on Discovery Coding
Yea, TIL, I'm a discovery coder. Always found planning early in Greenfield projects kind a pointless. Planning is almost step 3 or 4. I almost always prototype the most difficult/opaque parts, build operations around testing and revising (how do you something is good enough?), and then plan out the rest.
pj_mukh··on Stargate Project: SoftBank, OpenAI, Oracle, MGX to build data centers
I don't think we'll ever have a zero-crime society, neither should we aim to be one. But being left to the vagaries of police (and union) politics, culture and the complications of city budgets is clearly broken.

Example: Cities are being presented a false choice between accepting deadly high speed chases vs zero criminal accountability [1], which in the world of drones seems silly [2]

I don't want the police to have unfettered access to surveil any and all citizens but putting camera access behind a court warrant issued by a civilian elected judge doesn't feel that dystopian to me.

Is that what Ellison was alluding to? I have no idea, but we are no longer in a world where we should disregard this prima facie.

pj_mukh··on OpenAI fails to deliver opt-out system for photographers
Dumb question: Why does Etsy allowed clearly reproduced/copied works? AI or not.

Like selling it for money seems like a clear line crossed, and Etsy is the perfect gatekeeper here.

pj_mukh··on Why is homeschooling becoming fashionable?
I think a better question is: How did the median get so much better over 150 years, and why can't it keep getting better?

150 years ago, the average person was illiterate, poorer (in all senses of the word) and less connected to the world around them. Over a 100 year old grind, schooling fixed all that. Why can't it keep going? So the outlier, super special "phenom" today is the median of tomorrow.

pj_mukh··on Ask HN: How do you prevent the impact of social media on your children?
Right but speed demons don't nullify the need for Stop Signs and Speed limits.
pj_mukh··on Ask HN: How do you prevent the impact of social media on your children?
I do wonder what the dumb hammer of a blanket school ban is going to do. A bunch of states are trying that.
pj_mukh··on Tesla Sales Are Tanking in Europe
Same, and now I'm actually leaning towards a Plug-in hybrid because the legacy brands are so bad (bad range, bad charging network).

What a monumental dissolution in brand. I can only hope its felt quickly enough by Tesla's bottomline so it can a) either be reversed, or b) be an example to future entrepreneurs.

P.S: a) could be accelerated with some demonstrated excellence in Tesla Autopilot, it's possible, that would bring me back.

pj_mukh··on How we used GPT-4o for image detection with 350 similar illustrations
Just 4 images?! Damn. I’ve had to do at least in the 100’s. I guess it depends on the complexity of the segmentation.
pj_mukh··on Plasticlist Report – Data on plastic chemicals in Bay Area foods
Also, is there an aggregate plastic danger metric? It would be great to develop an aggregate metric that combines the different types of plastics and multiplies them by their known potential dangers to the human body. I realize the multiples will change over time as more research comes in, but right now, there's no way to quantify BPA vs DEHP dangers.

This would make the main giant aggregate list: https://www.plasticlist.org a lot more useful.

pj_mukh··on Show HN: I made a web app to bring children's drawings to life
Super cool. If you don't mind me asking, what model are you using?
pj_mukh··on One way to fight loneliness: Germans call it a Stammtisch
In Kolkata where I was born but didn't grow up, this is called "Adda" culture[1] at coffee houses. I guess in Germany they would call this Kaffeekränzchen. Super interesting how this pops up organically in most urban settings. Would love to join a new movement around this in my town.

pj_mukh··on The birth, life, and death of old Penn Station (2017)
Lots of sad, hysteric hand-wringing around landmark preservation. I agree that Old Penn Station was definitely worth preserving and kept away from development, but how deep does the rabbit hole go? Churches [1], sure okay some of them, Gas Stations?![2] You can see how the conversation quickly gets ridiculous. Lets come up with a comprehensive list once, revisit the list every decade, then BURY that NIMBY excu..I mean enlightened argument for all other development.

pj_mukh··on Amazon workers to strike at multiple US warehouses during busy holiday season
Unfortunately, Moravec's paradox has you jammed up. So for now, negotiate they must.
pj_mukh··on Launch HN: Innate (YC F24) – Home robots as easy to program as AI agents
Ohoho no way. Christmas comes early this year!

Edit: Turtlbot 3 Burger I suppose? Or Waffle?

pj_mukh··on Launch HN: Innate (YC F24) – Home robots as easy to program as AI agents
Love this. Thoroughly interested in jumping on this wagon.

Just throwing an idea out there: Instead of re-inventing the proverbial wheeled base, I wonder if it would make sense to build on top of some established wheel bases, like the turtlebot (https://www.turtlebot.com/). And then go ahead and build an array of manipulator/grasper options on top.

It’ll get you an established supply chain (including of replacement parts) and let you focus in on your specialty here: the reconfigurable agentic behavior stack.

It would be a no-brainer for me to jump on this and start building if the base was a turtlebot!

pj_mukh··on A pilot crashed a full passenger jet into the bay, didn't lose his job (2021)
" If the plane had come down in any other part of the bay, such as the 30-foot deep waters to its east or the dry flats to the west, Flight 2 would have either sunk, or likely set ablaze"

Wait wait wait, plane fuselages don't naturally float? I always assumed they did?

pj_mukh··on Elon Musk wanted an OpenAI for-profit
"Basically, people who use Office have extremely specific expectations."

Interesting point, but to OP's point- This wasn't true when Office was first introduced and Office still created a domineering market share. In fact, I'd argue these moat-by-idiosyncracy features are a result of that market share. There is nothing stopping OpenAI from developing their own over time.

pj_mukh··on Assisted dying now accounts for one in 20 Canada deaths
My dad (age 75) got diagnosed with ALS and within a month of the diagnosis opted for MAID. He had only just lost control of one leg, but he knew what was coming. As much as we begged him for more time, he didn't want any of it.

Till his dying breath he kept repeating how thankful he was that he lived in a country that didn't force him to live on when he didn't want to.

He was a clear Track 1 case, and I realize Track 2 cases are more complicated, but just wanted to add my story as reporting on MAID spins out of control in our culture war milieu.

pj_mukh··on Launch HN: Azalea Robotics (YC S24) – Baggage-handling robots for airports
That's not how this works. Most airports are looking to expand, they can keep the same staffing levels with a rapid expansion in throughput with these machines. (Assuming the unions allow it).
pj_mukh··on Launch HN: Azalea Robotics (YC S24) – Baggage-handling robots for airports
Super cool! You are additionally going to be saving a lot of workers from getting chronic back pains. I thought maybe y'all are going too slow, but after looking at some baggage handling videos, it seems like you're at a comparable speed already?

In deployment these things are probably going to be on some kind of cart system, I presume all your algorithms can handle small changes in the XY travel plane (i.e. the robots location w.r.t the end of the belt).

pj_mukh··on GM exits robotaxi market, will bring Cruise operations in house
For reference: "Ford BlueCruise is a hands-free driving assistance feature that allows drivers to take their hands off the wheel on certain preapproved roads"

"It seems like drivers did not find the feature compelling and were not renewing. Interest in autonomous driving appears to be cooling across the board."

No, because BlueCruise sounds like an asinine feature. To make me pay $2450 more for a car for some arbitrary selection roads for that feature to be available doesn't make sense to me.

Cruise really was on to something, well w/e GM's loss!

pj_mukh··on My second year without a job
Stories like this make me the most mad at the Landlords/NIMBY's (sometimes the same people). An $80,000 "investment" into a one person startup should take you much much much farther than this, but it is completely gobbled up by literal rent-seekers.

BAcK iN mY dAy a room in a house would cost $400-$500/mo in most places in the Montreal-Waterloo corridor. Now runways have basically been halved (0.3x'd?) as an extra allowance to the landed gentry.
