A decent L2 charger should be installable at scale for ~$1K per unit IMHO. I'm basing this on the fact that a singular L2 home charger can be installed for about that. Figure the industrial variant costs a little more, but you get savings from the mass scale of deployment. They probably cost more now, but competition will bring it down as we scale.

Also, not everyone will even need L2 everywhere all the time, because many will be able to charge at home or use fast-chargers in emergencies. You don't have to be near-full at all times. You could deploy them at only 1/N spots, say something closer to 1/4 of all the spots, if even that (apartments might need 1/1, but streets and business parking lots/garages would need far less. You don't need them in any short-term street parking areas, as L2 is mostly-useless unless the car is sitting in place for hours).

You also don't necessarily need to have the raw power to run them all simultaneously: you can have local groups powershare (e.g. deploy 8 chargers with a feed-in that supports 4, and the chargers can coordinate to drop their charge rate as more people plug in).

If those wild assumptions are true ($1k, 1/4 of parking spots), LA's bill drops to $1.5B, which seems much more reasonable. The capacity will build up organically over time as EV adoption grows, starting with corporate and apartment parking lots.

I think in this hypothetical all-EV future, there would be other compensating changes to the city as well. Like, all gas stations would go poof, and their tanks, and the fuel delivery trucks, and most of the refineries, and all of the associated impacts on peoples' health from both the fueling and the car exhausts, etc. There's a lot of potential upside to offset any reasonable electrification costs.
> Viewship is an easy metric to collect but it ignores perceived value

At a previous analytics job we were working for our client, one of the larger streaming platforms as were trying to quantify value, and more importantly attribution.

Attribution was huge and was still being worked out by the data scientists and then re-worked by marketing C-Levels at the platform. By the time I left, If you signed up for the service and immediately watched "Big Movie" as your first watch, or you finished >50% of "Big Movie" within the first of signup then "Big Movie" was the attributed thing that got you in.

This helped drive decisions (or helped "justify" in retrospect) for day-and-date movies (play on the platform + in theaters same-day), or to take what would have been a theatrical and put it only on streaming.
We took the tradeoff in our product due to the strong performance upside.

Our reasoning goes something like - whatever happened approximately at the edge of the power-loss abyss is considered part of the explosion. We have never held out hope that we'd be able to get information to disk up until the last microsecond.

Letting WAL roll us back a few transactions is not a huge deal for our customers. Even if this breaks logical consistency with regard to external systems. We have many degrees of "redo" and the back office is always going to be a thing in our line of business.

We file this under the "edge cases not economically worth targeting" bucket and take our 2 ~free orders of magnitude.
One of the plot-lines is getting the Primer mass produced for the seven float orphanages. The Primer is designed to react to its owner's environment and teach them what they need to know to survive and develop. It can do so by using human actors (in the theatrical sense), but it is not the case that a human is the tutor using the Primer like an encyclopedia, as your post seems to suggest.

I am glad that regulation prohibits human trafficking, despite the 'loss of choice' business owners have as a result. Prohibition is never perfect, but there is certainly a lot less human trafficking than if the market was less 'authoritarian'.

That's clever. We also have a central smart meter in the house. It has a standard port (I believe it's called "P3") that allows you to read out usage. There's devices on the market that plug into this port, connect to your Wifi and then make it available to a mobile app. It reports total power usage in real time and gas usage with a delay of 15 mins.

I would recommend anyone to do such tour of the house. You're very likely to learn a lot and be in for a shock here and there. Totally agree with you that most people are far away from a state of micro managing energy, there's big wins to be had with little sacrifices in convenience.

And yes, that was the background of my question: If I'd save 210$ in electricity per month, my very first question would be why I even use that much in the first place. Could be valid reasons for it, of course.
There are randomised controlled trials of diets (without caloric restriction). They show that some diets are better than others for real clinical endpoints, eg mediterranean vs low fat diet for secondary prevention of cardiac events [1]. The effect size in that example is not small, it is large, despite most participants already being on a statin. This data shows that diets are biologically active and significantly impact health. Therefore, the philosophy you espouse cannot be correct, or at least needs to be heavily modified.

First: I don't go out in snow beyond a couple of blocks, things can wait. But that's me.

Second: Just because the snow stops falling doesn't mean the problem goes away. The snow can take a couple of weeks to melt (essentially until the next rain, or a hot enough day), so stopping and waiting for nature to resolve the situation on its own would shut down the city for a month or so every year.
That doesn’t make sense, a lithium battery is heavier than an engine in the differentials we are talking about.

That’s a script for the reverse-engineering tool Ghidra that uses GPT-3 to de-compile machine code and to write plain English explanations of what a piece of code does.

This one is more recent and lacks that good write-up mentioned above. The script is smaller and it seems to have fewer features.

We evolved as hunter gatherers and have been hunter gatherers for most of our history. Continuously moving while collecting resources, even into old age. Today, most people don't continuously move. They go from bed, to work, to the couch at home, then to bed, with as little physical movement as they can possibly do in between.

Maybe if more people at least simulated how much a hunter gatherer moved a day, we'd see a much healthier population versus continuing this sedentary behavior that we have not evolved to do while remaining healthy. Agriculture which enabled a sedentary lifestyle for many people did not happen long enough ago for our species to be well adapted to this behavior; it was only 10,000 years ago, while our ancestors had been hunting and gathering for at least 2 million years, likely foraging even longer still.

It's not the same. In the SSL case the browser gives you a bypass button, which is fine (if hidden). Here, there is no bypass button unless you have the secret knowledge to open the app in a certain way.

Otherwise the OS entirely refuses to open the app with no bypass button or hint as to how to get around it, while implying "security issues" and "untrustworthiness"
We have plow trucks but we don't have a lot of room to store a huge dedicated fleet.

If you use it right you can absolutely get complete working things like “an HTML file that contains a Preact app that calculates a tip”. You just need to give it more to go on, ideally building it up with a series of questions and answers in one thread. And then you can often ask for the complete thing and it will spit it out perfectly without silly errors like JSX syntax in HTML. I’ve found those kinds of silly errors tend to happen when you give it a very concise request that requires a complex response. Just break it down a bit like you’re dealing with some kind of idiot savant.
Lousy engineering and poor oversight of how the designed systems interact, and lack of KISS solutions such as manual overrides may have contributed. One theory:

The engine surged power because it thought there was a danger of stalling the turbine, and whatever mechanism was supposed to get rid of such potential excess thrust didn't work or wasn't implemented.

Right, a power cut or kernel panic. It's certainly something to be aware of, but there are probably much more likely ways to lose some data (programming errors, etc).
My argument has always been that making unmotivated (it's remedial and annoying work for them), math experts, ie people that probably have never struggled with math in their life, teach entry level math to lots of people who don't "intuitively" get things like the teacher did 20 years ago, has been a huge mistake. These professors never seem to understand what it's like to NOT understand calculus.

The anecdote I always reach for is find someone who has been taught a higher level math subject by both a university professor, and an adjunct or local community college professor who might not have higher level knowledge of math. Many people prefer the "less expert" teacher.

Consider if you have been in software development for a long time, and how hard it is to remember what NOT understanding a variable was like.

As a data point: under carb restriction and fasting, I won't think about food at all until I happen to eat some threshold number of carbs, or I get actual hunger (shaking, weakness, headache --- usually around 20 hours in). Once I cross that carb threshold, I'll be snacky until I go to sleep.

People have different metabolic situations, but if you haven't tried fasting+restriction, it's pretty interesting.

Could always be an auction-based market - you start with a trial and only do a day/week/etc and gauge your results - if they're good you know you can bid more next time. With enough "liquidity" on either side the true price of said ad inventory will naturally come up without any tracking necessary.

> In the past, scientists and the public often thought that those with obesity simply lacked the willpower to lose weight. But evidence is growing that most people’s bodies have a natural size that can be hard to change.

In the context where we have gone from obesity rates of 13 percent to 40, to suggest that people have a natural weight and that's the cause of this seems absurd to me.
The paper specifically discusses that option (making local conform to remote abstractions) but finds it inadequate for various reasons. Stated succinctly: "Rather than encouraging the production of distributed applications, such a model will discourage its own adoption by making all object-based computing more difficult."
Even better the higher volume you go. On DigiKey right now, a reel of 100,000 5K1 resistors is literally $105.00. At two per USB-C port, that's a unit cost of 0.21 cents per device. Literally a fifth of a penny! Plus maybe a few extra seconds spent by the industrial sized pick-n-place machine on each device
That is so obviously untrue that it's hard to accept the statement as good faith. Successful litigation requires that the plaintiff be able to prove not only that harm occurred but that it was directly and exclusively the fault of the defendant (which quite notably does not work for diffuse/delayed/complex environmental harms), against a corporate legal team that often has more information, experience, funding, and patience. Even then justice often comes too late. Such an approach would also result in a court system so large that it would be more burdensome (and subject to corruption) than even the worst regulators today.

Litigation has never been, and will never be, an adequate substitute for judicious regulation. Many harms are very real, and serious, and well recognized as both, without being litigable. To suggest otherwise is tantamount to saying externalities should just be ignored in the name of profit.

It wasn't changed, it's just that there's more than one issue at hand: the earlier decision was that hiQ didn't violate CFAA, the later one was that it did violate LinkedIn's EULA. The November 2022 ruling specifically states that hiQ "accepted LinkedIn’s User Agreement in running advertising and signing up for LinkedIn subscriptions" - keep in mind that LinkedIn profiles haven't been public for a while in a sense that logging in is required to view them, and thus to scrape them.

Hence why OP is saying that this all will lead to increase in paywalls and such, and a reduction in truly public content.
> to escape weight stigma, rather than to serve a true health need

This is an unfair framing by the researchers

For a while I worked in pharma on a drug program for a harmless* "ailment", nail fungus. What I learned is that some people suffer serious psychological consequences, such as marital issues or avoiding situations where they might be barefoot, like the beach. People who have it in their hands may avoid social situations all together, which is even worse and reduces life expectancy.

We have a natural cultural bias in this regard. It's not just the phantom of the opera: in films the hero usually has a clear complexion and the villain often does not (not always to the extent of Darth Vader of course). Now we understand more about disease etiology this bias is no longer helpful, and is in fact destructive.

Losing weight addresses true health needs (increased rates of cancer, cardiac issues etc) but weight stigma has important side effects as well.

* The various fungi that attack skin, scalp, nails etc eat a particular shape of squalene which some people make (referred to unfairly in the medical literature as a "squalene defect"). You're not going to catch it from another person -- there's a good chance you're breathing the spores right now. Either you're genetically predisposed or you're not. And all it does is munch on a tiny amount of your body and causes no other problem.
It depends on what you're trying to do. If you're trying to query revenue then that's usually stored in a third-party system like Stripe. If you're tracking metrics then those can be aggregated into a time series database like Prometheus and viewed through Grafana.

It's definitely a trade-off. Isolation is pretty compelling for a lot of mid-market and enterprise customers but it does come at a cost of making it a pain to query across customers. But then again, that's kinda the point. :)

There's a great concept that I found out about reading Schlock Mercenary (a sci-fi webcomic), about using a gas giant as an interstellar spaceship [1]. It probably originates elsewhere, but it was nicely explained there. You build a "candle" (huge tube) that is inserted into the gas giant on one side, then ignite the gases inside it (iirc the comic uses fusion reactors on both ends, and an intake in the center of the candle). Both ends of the candle are open, "inner" end counteracts the gas giant's gravity to keep the candle from sinking into the core, the other end produces thrust. You put your payload on moons that orbit around the gas giant, and steer by moving the candle. The "thrust end" of the candle also doubles as a light and heat source for the moons, replacing the sun while in interstellar space. There are... some risks involved into the whole operation.

My favorite FAQ
Could you help me understand what it means to "pump entropy out of a system"?

I asked ChatGPT and it claims "It is generally not possible to "pump" entropy out of a system in the same way that it can be added to a system. This is because the second law of thermodynamics states that the total entropy of a closed system will always tend to increase over time."

It feels like if Apple went far enough to make this all visible and great, they’d start getting scrutiny for being imperfect, and missing malware.

It's VERY hard to keep a vehicle run straight with non-mechanically-tied wheels, you'll almost never get a "perfect enough" balance ending up in an engine pushing/pulling against the other.

That's why for instance we do not have much multi-motors EVs without a mechanical coupling...
Having an interest in Sqlite and LiteFS, but not having explored either very much, I wonder what the DB administration aspect looks like?

Say I want to connect a SQL client to my production DB do I expose a port on my production app that speaks the protocol? Or maybe I have a separate container that is basically just the Sqlite replica that I can connect to? Or maybe there is some other approach that I'm just not seeing?

Fly, Sqlite, and LiteFS is definitely an interesting combination but I'm still sort of mentally stuck in the managed (and standalone) DB model.
This is an old paper that is not super meaningful these days. Distributed computing has transformed radically in the past three decades. In the 80s and 90s, there were few useful distributed systems, and we only had a rudimentary idea as to how to build them. Now we run planet-wide distributed systems for billions of users. The lessons from the 90s are no longer very useful.

Does the type of sugar, or type of fat not play a part here?

HFCS is notorious for the bad effects on the body, versus something like honey.

Same for the Intuit, simpler animal fats vs hydrogenated "trans" fats?

I feel like the key difference in their diets is it's not overly processed and full of things we've decided to put in there for cost reasons (corn subsidies making HFCS cheaper than cane sugar, and trans fats are cheaper than more expensive animal products).
I don't think it's half-plausible to compare Hadza or Intuit diets to a Big Mac and a soda. Neither transfats nor processed sugars are in the Hadza diet, just for example.
