jackmott42··on NASA says distant exoplanet could have rare water ocean, possible hint of life
Data is open, you can check. Hell you can even propose your own time slot of webb if you want.
jackmott42··on Superbatteries will transform the performance of EVs
The energy density of the battery cells in the first leaf was the same as the chevy bolt today (to close approximation). The cost just got cheaper so they could add more.
jackmott42··on Half of Glaciers Vanish with 1.5 Degrees of Warming
Well since my kids will die with that attitude, I have to say you are a horrible person.
jackmott42··on Half of Glaciers Vanish with 1.5 Degrees of Warming
These are standard talking points that people parrot and both of them are misleading. There did exist a global cooling idea and it was in some pop sci magazines, but it was never a serious prediction by the climate change community. Even in back in the 1970s we had a pretty good idea how much warming would result from adding co2 into the atmosphere:

To your second point, predicting the total heat of the Earth is also easier than predicting what the weather will be at one spot on the globe in any given moment. The former has only a few inputs (the sun) and outputs (back to space!) But how that heat swirls around in the atmosphere and moves to and from the oceans is pretty complicated.

which lie are you referring to specifically?
jackmott42··on Bletchley Park codebreaker Margaret Betts has died
I don't like how much it alters the real history, but if the movie was fun for anyone, get some good books about the same events and you are in for even more fun! It wasn't just "Break the code, done" in real life, there was back and forth math and engineering battles, it was great stuff.
jackmott42··on Bletchley Park codebreaker Margaret Betts has died
Turing talking all weird was also not real, but him being good at running was, in fact he was maybe olympian potential in that era.
jackmott42··on Bletchley Park codebreaker Margaret Betts has died
For those who have seen the movie and her struggles with sexism to get a job there, it is important to note that in real life the way she got in at Bletchley, was they called her immediately because she was known to be one of the best.
jackmott42··on X/Twitter has updated its terms of service to let it use posts for AI training
Threads is really nice, has a web version now, and text search coming very soon. No need to help fund insurrection at twitter.
jackmott42··on Police Seized Innocent Peoples Property, Kept It for Years. What Will SCOTUS Do?
Get ready, because Scotus is writing such a defense right now.
jackmott42··on Shell abandons its plan to offset CO2 emissions
There is no regulation proposed, or method proposed, to substantively reduce how much co2 is emitted when you burn fossil fuels for power. That is why this problem is so hard. You can't put a filter in place like you can for heavy metals or particulates. There is no solution other than switching to nuclear/solar/wind/etc
jackmott42··on Weight-based motor vehicle tax
you mine for battery materials once. with an ICE engine you mine for oil over and over and over again, and you burn more fossil fuels to refine it, and burn more to transport it to you, over and over and over again.
jackmott42··on Weight-based motor vehicle tax
Can you show the total lifecycle math where you worked this all out, or are you just asserting it without evidence?

How much bigger and heavier is an electric SUV vs a regular one? How does a ModelY compare to a Mazda CX-5 for instance?

jackmott42··on Bicyclists Deserve the Right to Free Movement
Maybe since you don't understand it, you should quit asserting why they do it, maybe you should talk to them sometime. I'd be happy to talk to you about it.
jackmott42··on Show HN: Fast vector similarity using Rust and Python
Rust supports SIMD intrinsics
jackmott42··on Chandrayaan-3 Lands on the Moon
Yeah, a lot of people have this idea that you fight misinformation with calm, collected, rational argument.

Well, I guess I need to prepare a cold, calm, collected rational argument about how that isn't at all effective, heh.

jackmott42··on Tesla asked officials to redact info of driver-assistance in use during crashes
More hardware can improve reliability of a few things but doesn't address the fundamental problem, which is that Tesla FSD has no coherent way to deal with novel situations, which happen all the time when driving. IMHO we won't see "Go to sleep and drive somewhere" until there is something like a general reasoning neural net on top of the ones doing the object detection and physics and such.

"That looks like a firetruck" says the object identication net, "but after reasoning about it, it is actually just a mural on the side of a building"

And nobody knows how to build such a thing yet so it might be a long time.

jackmott42··on NY Times Rides in Waymo Robotaxis in SF
We have a shortage of fulfilling jobs too, and a shortage of jobs that pay enough to ever afford a home.

Ever wonder why people are bored enough to make up Qanon conspiracies, believe them, and start an insurrection over total nonsense? Too many people with nothing to do and nothing to live for.

jackmott42··on Xbox’s new “8 strikes” mod rollout judges hate speech 3x worse than cheating
So when I started playing PlayerUnknown's battlegrounds, you started in a lobby, everyone is there and can talk. Almost every time someone would be yelling "Nigger nigger nigger nigger nigger" endlessly.

It was really nice when the game developer took action to get rid of that. I'm not sure I understand your view that this is a bad thing. There are still games with player run servers that can manage things on their own, but some games, like pubg, can't function that way.

Are you just an awful person that is mad you don't get to be awful any more?

jackmott42··on Solar-Powered Electric Motors for EVs That Never Plug In
It doesn't help with being stranded on any normal car. Better off walking.
jackmott42··on Solar-Powered Electric Motors for EVs That Never Plug In
regarding #6:

The Aptera can do pretty well on just solar charging, enough that many people could commute every day and never plug it in (if they can park it in the sun every day, which you can't)

jackmott42··on Moderna CEO made $400M last year–2,435x the median salary of employees
The end game for america is either a few elites living in gated communities with the rest of us living in filth, or revolution ssss
jackmott42··on Fresh evidence of ChatGPT’s political bias: study
Being politically neutral right now when imply you are complete deranged.
jackmott42··on Fresh evidence of ChatGPT’s political bias: study
Good, we don't need the robots being ignorant, racist, insurrectionists also.
jackmott42··on Fresh evidence of ChatGPT’s political bias: study
Current conservative americans have already noted amongst themselves that their policies are problematic because reality has a liberal bias.
jackmott42··on Fusion Foolery
>It's cheaper to install and operate solar than it is just to operate a coal plant.

When you say this you need to also talk about how much it costs to build enough energy storage for solar to become some given percentage of grid power. There is probably some % where it stops being cheaper than coal

jackmott42··on Tesla’s $10k-Cheaper Model S, X Are Software Locked for Less Range: Report
For what use case? I've never had to charge my EV anywhere other than at home unless I'm on a road trip, and I only charged it up to 50%
jackmott42··on Tesla’s $10k-Cheaper Model S, X Are Software Locked for Less Range: Report
There is nothing special about 100% or 80%, for all current chemistries in cars, the battery ages faster the higher you charge it. There is a little bit of a step change around ~60% so keeping it below that is good for days when you can.
jackmott42··on Tesla’s $10k-Cheaper Model S, X Are Software Locked for Less Range: Report
That is the view of a lot of 20 somethings that haven't seen how people really work yet.
jackmott42··on Tesla’s $10k-Cheaper Model S, X Are Software Locked for Less Range: Report
The sensible thing would be for it to stop charging at actual 75% and then as the battery degrades unlock the unused range gradually so it appears like there is no degredation for a decade.

and in 5-10 years your range may match your neighbors with the expensive one.
