jackmott··on Kickstarter shuts down campaign for Unstable Diffusion amid changing guidelines
People weaponizing “non consensual porn” to attack this are going to also need to ban pencils, keyboards, and police thoughts. good luck!

and merry christmas

jackmott··on The cold hard truth about electric vehicles in winter
You only need a 220volt plug, then its fine.

You can also leave it overnight just fine. I think plugging a 110v during the cold is kind of an edge case, the car tries to charge but it makes thing worse. Maybe a software update would cure that.

jackmott··on The cold hard truth about electric vehicles in winter
My father in laws truck wouldn’t start this winter in texas because the diesel froze. My EV worked great and thanks to the low temps the battery will be degrading a bit slower with age for a few days.

But yes I take a 15% range hit

jackmott··on Are Progressives in Denial About Progress? Yes, but So Is Almost Everyone Else
I am a progressive and I think the speech codes are silly and sometimes even harmful.
jackmott··on How the McMurtry Electric Fan Car Clocked a 7.9-Second Quarter-Mile
Never has a car elicited such emotion from the crowd, it is amazing to see
jackmott··on How the McMurtry Electric Fan Car Clocked a 7.9-Second Quarter-Mile
The track still wasnt dry, you can see the moisture
jackmott··on Kia’s new EV6, driven
EVs don’t normally have a transmission to break. just reduction gears which are beefy.
jackmott··on Highway EV charging will soon need a ton of power
solar cells can have a decent impact on very exotic efficient designs like the aptera. On a normal sedan it is better to put the solar panel elsewhere than the car
jackmott··on Neuralink faces federal probe, employee backlash over animal tests
plenty of accurate ways to critique elon, no need to make yourself look foolish by suggesting tesla and spacex and other ventures are just ponzi schemes.
jackmott··on Tesla Semi, a Deep Dive
you can reverse engineer how big the battery is from stated range and efficiency. around 900kwh plus or minus 50
jackmott··on Author warns about 'epidemic of self-censorship'
But you forget to mention that the disagreements are things like: “I think you dont have the right to exist because you are gay or black or non christian “ or “nevermind democracy trump should be president even though he lost”

People aren’t getting cancelled because they think taxes are 5% too high

jackmott··on Why are male testosterone levels falling?
You are making strong assertions that are not strongly supported by evidence. Strong emotional reactions can happen for all kinds of hormonal disruptions including both added testosterone and all of the indirect consequences of using it (such as excess estrogen or other imbalances of that may result)

Absolutely some people can do massive amounts of steroids and have no aggressive tendencies, but other people immediately have problems. Its rather notable in some circles, like masters sports where lots of men are on TRT

and who knows what subtle psychological effects are at play, decisions being swayed by your new hormone makeup. Would make for fascinating research delving deeper

jackmott··on Russia strikes nuclear plant in south Ukraine, damaging power plant buildings
“good, leave. invading another people is abhorrent”

The invasion is the war crime and should have been enough for the whole world to respond en masse to refuse allow it.

The world should do the same if the USA ever invades anywhere again as well.

jackmott··on Why car wheels are so flat these days
Gearbox serves more purpose than just getting the power to the wheel, it also improves the efficiency of the motor and\or expands and optimizes the usable speed range of the motor.

Also cars can stop way harder than any regen can, massive amounts of energy will be at play and likely any solution is more complex than just grabbing a rotor, which is a more direct way to heat dump

jackmott··on Why car wheels are so flat these days
Well the fragility of low profile wheel/tire packages is true at least
jackmott··on EV adoption in US is happening faster than predicted
Privacy reasons? All the privacy concerns are going into both types of cars.
jackmott··on Declining quality of consumer-grade products – 2009 fridge compressor autopsy
Could it be because the information age causes companies to compete on price much more aggressively? You can’t easily prove that your fridge really will last longer, but easy to price the price is low.
jackmott··on Why aren't smart people happier?
Seems like the correlations between IQ tests and life outcomes related to this ill defined questions does imply a degree of crossover in rotating shape skill and dealing with the ambiguities of life. However that is probably genetic or due to early development , not something where practicing shape rotation to improve it further will improve your marriage or relationship with your kids.
jackmott··on “Autistic people can’t acknowledge when they’re wrong”
Yeah it is either a fantastic bit of art or hilarious lack of awareness of the irony. The guy actually reminds me of a coworker that I like a lot who is on the spectrum. Once in a meeting a manager was describing why we needed to do some task. Autistic coworker: “oh so we need to do it for political reasons”. and manager starts to freak out and backpedal trying to say its more than just political reasons. Autistic coworker, calmly: “oh no its ok, political reasons is fine!”
jackmott··on Counterfeits, fraud, and theft: Why Silca changed its return policy
Josh is a great person and the internet is also full of in depth aerodynamic and rolling resistance information thanks to him.
jackmott··on New third-generation Formula E car is fastest ever electric racer
It is all electric rear wheel drive with two fans that suck it to the ground, and the skirt lasts a long time!
jackmott··on Mission to reach and operate at the focal region of the solar gravitational lens
These are all easily solved problems we are familiar with compared to getting spaceships there accurately. But yes usually these plans call for a swarm of these ships
jackmott··on Tesla remotely converts battery pack, cutting 1/3 of range
All cars are doing this stuff, it isn’t EV specific
jackmott··on Tesla remotely converts battery pack, cutting 1/3 of range
It certainly echos the approach of other tech companies like google and apple. Save money and reduce risk by not giving your employees any power or freedom to think on their own. Or not having employees even exist when possible. The customer suffers but the customer is also the sucker who used your service because it was the cheapest or free.

its all gross and unnecessary

jackmott··on Two weeks in, the Webb Space Telescope is reshaping astronomy
It isn’t uncalled for, what is uncalled for is how in the modern era you can’t talk about fucking anything without a conspiratorial interjection like yours, always without evidence, derailing fucking every conversation and every attempt to do something good. stop.

jackmott··on Quick Tips for Fast Code on the JVM
>.(I usually write apis that are utilized by end user apis).

When that is the case you need to think long and hard about performance, because it needs to not just be fast enough for you, on your machine, but on any conceivable end users machine, for any conceivable end users idea of what responsive enough performance is, for any conceivable end uer's work load, which might be vastly different or larger than anything you intended.

further I don't think it is always the case that faster code is less simple. Often the faster option is more simple. Avoiding unnecessary complexity is often a win for performance too, and understanding memory locality and how the garbage collector work allows you to make smarter default choices which often have no net impact on simplicity

jackmott··on Some excerpts from recent Alan Kay emails
> I also suspect that programming languages have not advanced in any significant way since around 1990

I would have said not much since 1970? 1950? What big new things have their been?

they don't teach excel in the comp sci department at Rice.
jackmott··on BMW delivers its 100,000th electrified vehicle this year
>but it's basically so misleading as to be a flat out lie that those cars are electric.

If plug in hybrids count but non plug in hybrids do not, then I disagree with you.
