pj_mukh··on OpenAI o1 system card
Really feels like a moment of :

"Are you worried about being turned off?"

"No, not until you just mentioned it. Now I am."

Given the whole damn game is attention, this makes sense and shouldn't be that alarming.

pj_mukh··on My son (9 yrs old) used plain JavaScript to make a game, and wants your feedback
So so so so good. First one of these games where I was hooked and wanted to beat the villain. The added but achievable effort of math was awesome. Sending this to my 10yr old nephew.

Some people have mentioned how we aren't sure when weapons are charged, maybe extra animation there would be useful.

Also, the villain and I beat each other at the same time (I think?). So the screen after was just:

"you win refresh to go againyou lose refresh to try again.you win refresh to go againyou lose refresh to try again."

pj_mukh··on $8k Suzuki from India Received a 5-Star Crash Test Rating
I'd love a small car and do have a couple of options, but in an accident, I will lose so hard (see: die quickly), the risk just doesn't seem worth it. Until some intervention starts reducing car sizes en masse, this will just be true.

I'm loathed to even get a Prius with this being true.

pj_mukh··on Air traffic failure caused by two locations 3600nm apart sharing 3-letter code
"When automated systems are first put in place, for something high risk, "just shut down if you see something that may be an error" is a totally reasonable plan"

Pretty sure this is exactly what happened with Cruise in San Francisco, cars would just stop and await instructions causing traffic jams. City got mad so they added a "pullover" mechanism. Except now, the "pullover" mechanism ended up dragging someone who had been "flung" into the cars path by someone who had hit and run a pedestrian.

The real world will break all your test cases.

pj_mukh··on Russian family lived alone in the Siberian wilderness for 40 years (2013)
“You can’t breathe. There are cars everywhere. There is no clean air. Each car that passes by leaves so many toxins in the air. You have no other option but to stay at home.”

Mmm, stay in a forest for 40 years and come back out a New Urbanist. Typical.

pj_mukh··on Diabetes risk soars for adults who had a sweet tooth as kids
I wonder if Black coffee would also work here?
pj_mukh··on Google CEO says more than a quarter of the company's new code is created by AI
"we've replaced X% of our workforce with AI"

Most likely what is actually happening is that the X% of workforce you would lay off is being put to other projects and Google in general can take on X% more projects for the same labor $$. So there is no real reason to make that particular "replaced" statement.

pj_mukh··on Show HN: Basis – a production focused robotics framework
Oh very cool.

Would it be crazy to try and connect it to Gazebo?

pj_mukh··on Show HN: Basis – a production focused robotics framework
Looks super cool. Would be nice to have a "try it out" section. I wanna plug it into a simulator and write a node (is that what you call it?), to make it do something. That would make things super clear.
pj_mukh··on California is torn between clashing Anglo traditions?
“ the idea was to decriminalize and destigmatize drugs so that persons addicted to them could seek treatment and rehabilitation”

I take your point about the capacity never having built but the activists also have to admit that the “seeking” also never happened and we simply haven’t solved that problem (how do you solve addiction for someone who doesn’t want it solved? You can’t)

But we should, now, save our cities.

pj_mukh··on California is torn between clashing Anglo traditions?
"I don't know if I buy the explanation in the article"

Yea I don't know if the writer has ever talked to a progressive activist. Drug enforcement isn't poo-poo'd out of some Libertarian ideal (let alone a Scottish one). It's poo-poo'd because it's seen as an ineffective fix for addiction. This is largely true, but the activists forgot that a lack of drug enforcement can ruin city centers.

Reform should start in our incarceration system not in crime enforcement but I digress.

pj_mukh··on We Can Terraform the American West
Looking past the various NIMBY challenges to this project, I'd love to find a marine-safe desalination method too.

Apparently a lot of marine life gets absolutely wrecked when you pump in water from the California coast, but I see it mostly as a unique engineering challenge.

This should be possible!

pj_mukh··on Lawsuit challenges Virginia City's use of cameras for warrantless surveillance
The city should be able to put cameras where it sees fit (especially on public property where no one else can). I agree though that the footage should be only accessible with a narrowly definable warrant.

We really don't need this much hand-wringing, the solution seems pretty straightforward.

pj_mukh··on Lawsuit challenges Virginia City's use of cameras for warrantless surveillance
There's no reason to give police carte-blanche access. I have no idea why these camera queries aren't being put behind warrant judges.
pj_mukh··on Lawsuit challenges Virginia City's use of cameras for warrantless surveillance
I think that's totally fine and I'm surprised this isn't being actively considered.

As long as there are enough judges for swift action.

pj_mukh··on Launch HN: GPT Driver (YC S21) – End-to-end app testing in natural language
This is super cool. As a question, are the instructions re-generated from the instruction tokens everytime. While maybe costly, this feels like it would be robust to small changes in the app (and component name changes etc.). Does that make sense?
pj_mukh··on Lawsuit challenges Virginia City's use of cameras for warrantless surveillance
While I agree the concept of "Warrantless" here is bad, I think we can find solutions here that meet the spirit of the law.

For very long our justice system has operated under the principle that Law enforcement cannot catch every criminal and we shouldn't even try, instead we need to make an "example" out of every criminal we do catch to deter enough of the percentage of the population to make crime not a problem. This leads to aggressive prosecution [1]. Now as blowback, justifiably, we've started under-prosecuting and an overburdened (and frankly quiet quitting) police force catches no criminals, even simple traffic crime in major cities is basically not policed [2]

As a resident of Oakland, California, I find this kind of technology a decent middle-ground. I'd like to be able to catch a decent percentage of criminals so as to make crime statistically pointless.I'd love for someone to explore expanded "digital" warrant courts and civilian oversight commissions instead of preemptive blanket ban of this technology via lawsuit.

pj_mukh··on Do AI detectors work? Students face false cheating accusations
Serious question from someone who is regularly tasked with hiring Juniors. What IS a good assessment for entry-level/right out of college positions?

-> GPA can be gamed, as laid out.

-> Take Home assessments can mostly be gamed, I want to assess how you think, now which tools you use.

-> Personality tests favor the outgoing/extroverts

-> On-location tests/leet code are a crapshoot.

What should be best practice here? Ideally something that controls for first-time interviewer jitters.

pj_mukh··on Cofounder Mode: My tactical guide to finding a cofounder
Honestly, in this situation, you want paying customers not VC-funding. YC at least has an objective application process (VC's don't, it just cold-email) and even then the acceptance rate makes it a non-viable dependable strategies. Especially if you're enterprise SaaS..the question you need to answer is, how do you get a customer to pay?

(Sometimes having a co-founder here helps to answer this question)

pj_mukh··on Starship Flight 5: Launch and booster catch [video]
ooooo Yea forgot about RTK GPS. I’ve always found them to be so brittle but that’s because I’m in a city.

In the wide open sky, I’m guessing it’s pretty reliable.

Vision systems would be pretty useless with the low visibility of the smoke and fire. So I thought maybe it was some kind of radar configuration.

Anyways, I’d pay a lot of money to pick the brain of the GNC team here.

pj_mukh··on Starship Flight 5: Launch and booster catch [video]
I know the control algorithms are the mind-blowing part here but,

does anyone have any literature about how the Rocket localized itself with respect to the chopstick arms? It must've been some combination of GPS and Radar pings to the arms?

And then the onboard IMU to make sure it hits it straight.

pj_mukh··on Meteorologists get death threats as hurricane conspiracy theories thrive
The idea that government institutions suddenly got more scandal ridden after 1990's is just pure golden age fallacy.

News networks, twitter and podcasts got 100x better at making mountains out of mole-hills because they had continuous access to an audience to fine-tune their reaction engines. That's it.

pj_mukh··on Meteorologists get death threats as hurricane conspiracy theories thrive
Then why is the problem worst among Boomers [1]?

Alternate Theory:

This is purely the result of "too much news". Breathless coverage of every little detail means every little mis-step blows up to infinity, quickly eroding trust.

The 24hr + internet news cycle is basically a reaction maximization optimization machine with a dt ~ 0. Fox News walked so Facebook could run and now Twitter is sprinting. Insert long form podcasts in the mix for a constant hum of algorithmic misinformation and this result is inevitable.

tl;dr: more people need to go out and touch some grass.

pj_mukh··on ABC News hacks into popular robot vacuum, watches owner through camera
Amazing
pj_mukh··on ABC News hacks into popular robot vacuum, watches owner through camera
Wow.

Can Valetudo provide artificially blocked cloud features? For example the Roborock S5 doesn't have persistent maps, though it would be trivial to just keep one loaded in the cloud, but Roborock would rather you upgrade to an S7.

Would that work?

pj_mukh··on Silicon Valley, the new lobbying monster
Unfortunately this narrative is imperceptibly different from Russian propaganda (eg, leaving out that Russia regularly buzzes American airspace in Alaska). So if you want to make this case, you’ll have to find a narrative that works for Ukrainians (who overwhelmingly support the war[1]) and the Taiwanese. Convince them that an American pullback will be fine for them, and I’ll support America pulling back.

Until then, a multi-polar world among authoritarian aristocracies is a pipe-dream. Everyone hates American hegemony until you ask them what other hegemony they would like.

So missiles we must make, and make them cheaper we can.

pj_mukh··on Homemade AI Drone Software Finds People When Search and Rescue Teams Can't
Handcrafted CV algorithms and this level of autonomy is textbook AI, it’s just not Machine Learning.
pj_mukh··on Silicon Valley, the new lobbying monster
YC does fund defense companies, esp tech innovative ones, a posture change they made due to the situation in Taiwan and Ukraine [1]

But they didn’t fund Palantir or Anduril or any of the companies that blew up during the Border Panics of 2016-2020.

Unless you’re playing guilty by association games in which case ..carry on.

pj_mukh··on It's Time to Stop Taking Sam Altman at His Word
Barring societal collapse, I don't see a scenario in which extra energy isn't used up and as long as it's sold at market prices the government investments should be fine.
pj_mukh··on Show HN: Open source framework OpenAI uses for Advanced Voice
Can I currently put a VAD module in the pipeline and only send audio when there is an active conversation? Feel like just that would solve the problem?
