China is currently subsidizing electric cars pretty heavily and lithium-ion batteries are dropping in costs pretty dramatically over there.
Also with current tax-rebates you can get a chevy bolt for like ~20k. Which is a lot less than such cars used to be with that kind of range.
Prices might have gone up recently but if we compare EV prices from 5 years ago you are getting dramatically more for the money now.
Mostly as heat-exchangers continue to get efficiency gains, electric car prices continue to plummet, and solar continues to become more effective watts/$. While not all of these options will work for everyone, they will work for _most_.
It doesn't make sense to spent billions of dollars securing oil when we can spend millions switching to electrical infrastructure.
Mine stemmed from my quads being significantly more developed than my hamstrings / lower posterior chain. Any imbalance between the front / back of your legs/hips can cause tracking issues, which will then overload your IT band or in the case of walking backwards, your MCL.
Also pressure point therapy using a lacrosse ball right into the hip attachment of the IT band was one of the few things that gave me relief. Good luck.
I don't think we're going to see the performance increases past the ~10-20% each fab cycle now.
Performance per watt and having dedicated HW for video decoding / other tasks(AI?) I think might end up being the answer to the continuation of Moore's law. Especially considering that we are in the era of heterogenous computing.
(essentially condensing down milk products that don't have a large % of heavy metals but this gets condensed down and the heavy metals are more likely to stay behind - 200 liters of milk to make 1kg of protein powder).
The joke that isn't a joke is that you really need a CS degree to use git. It's not wrong.
The git default arguments makes for a very inconsistent experience, agreed.
And then `git checkout .` vs `git reset --hard/soft` vs `git cleanup` are all super similar but very different.
Still love it more than perforce/svn (I did like mercurial a little better back in the day but I doubt that might still be the case).
----- `git reflog` is king and shows you the truth.
Not sure if this is a bash hold over to differentiate ENV_VAR vs local reg_var or like an os/global constant naming hold over.
Generally if you call "env" on your cmd line (all of my)/most keys are ENV_VAR capitalized.
I think this would be one of the few times where I think that's useful. Typefaces take a lot of time and consideration and work to create so just blanket ripping off that work because we all take them for granted is kind of bullshit.
I have conflicting thoughts about this.
But at the end of the day if you only trained on open fonts they just aren't generally as good and the output should be not generally as good as opposed to training on nicer fonts that you technically don't have the rights to (but no one thoughts of this being an issue at the time of design patents / etc ).
But we're now in the world where we will pay money to compute an AI model to design fonts instead of just paying designers to design fonts. The race to the bottom is accelerating at an alarming rate.
Still love map. But reduce can feel very "code golf" real quick.
I hope she managed to keep all her files and didn't lose anything.
I'll provide a relatively simple example.
Just even attempting to design a starfox game clone where the ship goes towards the mouse cursor using euler angles will almost immediately result in gimbol lock and your starfighter locking up tighter than unlubricated car engine going 100mph and unable to move. [0]
The standard solution in games(or at least what I used) has been to use quaternions [1] (Hamilton defined a quaternion as the quotient of two directed lines in a three-dimensional space,[3] or, equivalently, as the quotient of two vectors.) So you essentially dump your 3D coordinate into the 4D quaternion coordinate, apply your matrix rotations, then convert back to 3D space and apply your rotations/transforms.
This was literally just to get my little space ship to go where my mouse cursor was on the screen without it locking up.
So... yeah, I cannot even begin to imagine the complexity of what a Boeing 757 (let alone a 787) is doing under the hood to deal with reality and not causing it to brick up and fall out of the sky.

I think it would be easier to just limit greenhouse gas emissions on earth.
Your point works pretty well considering that Venus has a a dense atmosphere unlike Mars.
The US navy devised a formula based on height age and your neck and waist circumference and was 2-4% accurate for body fat calculation (it's not good for tracking relative changes tho).
You can make generally fairly accurate assumptions about body fat percentage from a few key indices when it comes to general population.
The electrical impedance issue becomes more problematic when you have a higher muscle mass vs fat mass as the scale has a much harder time figuring that out (which is why some of the scales have an "athlete" mode on them).
Most of the good scales also have a handheld impedance sensor on them to track upper and lower body impedance for a more accurate measurement tho.
Python, Ruby, and JavaScript all have exclusively boxed values. "Everything is an object".
I'm not sure what languages you use but that pretty dramatically covers most of the mainstream (top 10 at least).
a 4000 HP train is ~ 2,000 kWatts. The average diesel-electric locomotive uses 3.5-4 kwh / mile of electricity (according to chatgpt). So to go 500 miles we're looking at 53,000lbs / 26.7 tons of _just_ battery (doubled up weight to account for non lithium). The locomotive itself can weigh 120-220 tons. A freight railcar can weigh about 100tons.
For a yard locomotive where they are just moving things around this could be super useful. For hauling freight around it's a potential? You're basically losing a freight car of cargo per 500 miles.
And I would really want this thing to be NOT made of lithium ion cuz if the train derailed it would be fairly destructive.[

If you are a non-us citizen or you're deemed "a terrorist" they can do whatever.
This complicates further with crap like the US spying on say Swedish residents and then forwarding information to Sweden. Technically; Sweden isn't spying on it's citizens, the US is. But it's the same result.
Looking at problems naively it looks simple but it's -really- not that simple if you want it to do WELL.
Having to time holding down left and then double taping it is an exercise in frustration.
Other than that it looks interesting, I enjoyed the moving platforms.
Thanks for bringing that up. Those were good times. And agreed. Would love the source to original EV alone. Gonna take a gander at maelstrom! Thank you!
Put another way; if an emergency team arrives late to another accident because they were tied up on a false positive from an iphone and that results in less effective care, what happens? Do we just front the bill for more emergency workers? Do we hold apple accountable for false positives? Do we hold the user accountable for false positives (I guarantee most people are gonna start turning it off then).
Seems like emergency response centers are a little mixed in how they feel about the feature. But this last point is especially important as to why false positives are pretty irresponsible.
"An automated call from Crash Detection could cost responders as much as $10,000, and they have a limited budget."
