Well, efficiently, at least.

You can always heat up a hot air balloon and have it yank a system of pulleys, but you're gonna lose a lot of energy that way.

Nuclear gets more expensive. That's worse.

Figuring out grid scale storage isn't easy, but the good thing about it is that you can figure out storage at slightly smaller scales to alleviate the problem somewhat, and build on that success to try to get to daily storage to meet nighttime demand, then up to weekly storage to handle fluctuations in weather, and maybe even seasonal storage to deal with seasonal variation in both supply and demand.

But storage doesn't have to just be chemical batteries, either. Some can be demand shifting, like desalination or water pumping based on excess power supply. Maybe even intermittently powering direct air capture of CO2 if there's so much excess energy they don't know what to do with it. Some can be storage of heat, whether really hot like molten salt that can run turbines for dispatchable electricity, or just at the residential scale with a bunch of distributed hot water tanks, or everything in between. There are also some storage technologies relying on gravity (pumped hydro if the geography supports it), compressed air, flywheels (could be important for maintaining grid inertia for stability).

And there's always curtailment, where you just don't generate the power, and turn off some the panels in the middle of the day.

Way too many birds.

But also I need to know about the maids a milking, the ladies dancing, the lords a leaping, pipers piping, and the drummers drumming. Like, this is a performance where the humans get paid and get to go home afterward, and not like a slave trade situation, right?

Okay, now solve for local transportation and create a single network that's highly optimized for both long distance, medium distance, and last mile solutions.

Why does it need to be a single network? A shipping container can go on ship, train, and truck pretty seamlessly, and that combined multi-modal network can connect sources and destinations that no one method is sufficient for.

And once you design an optimized network under your parameters, it starts to look like a hub and spoke model, with high volume arterial routes connecting the hubs, pretty close to how parcel delivery tends to work. And once you have that, you can optimize specific segments, including using hubs connected by air for time sensitive stuff (same day, next day, 2-day service), waterways or rail for really heavy or bulky stuff, and all sorts of intermediate methods or a variety of last mile delivery needs for the specific needs of any given package.

Probably. I don't even know how I came up with this, but I do love me some logic.

Sometimes 1+1 is 2, like when you're counting stuff.

Sometimes 1+1 is 1, like when you just need a Boolean indicator of whether something is true. Pressing the elevator button multiple times should behave the same way as pressing the elevator button once. Planning out a delivery route requires a stop at every place with at least one item to be delivered, but the route itself doesn't change when a second or third item is added to that stop.

Sometimes 1+1 is 0, like when dealing with certain types of rotations, toggle switches, etc. Doing a 180° rotation twice is the same as doing it zero times. Same with doing a reflection transformation twice.

A good engineer understands the scope of what they're doing, and its limits.

That's why the county level data makes the trend that much more obvious, because the states tend to clump big groups together. Here's an example.

There, you can see that Colorado is special in that its rural counties tend to be low obesity, compared to even its neighbors in the Rockies. You also see a sliver of green following the Appalachian Mountains.

And obviously it isn't the only factor. Poverty is really important, as are lifestyles (and the intentional and unintentional features of any given community in incentivizing or disincentivizing things like walking, regular exercise, eating healthy, etc.).

Altitude is an appetite suppressant.

The trend of altitude being inversely correlated with obesity rates is really obvious from county-level data. That trend persists across multiple countries, but the specific correlation varies from country to country, in a way that suggests that rich countries have a stronger inverse correlation between altitude and obesity.

Contracts can be modified by the bankruptcy code.

In 11 U.S.C. § 365(f)(1):

Except as provided in subsections (b) and (c) of this section, notwithstanding a provision in an executory contract or unexpired lease of the debtor, or in applicable law, that prohibits, restricts, or conditions the assignment of such contract or lease, the trustee may assign such contract or lease under paragraph (2) of this subsection.

So any continuing contract in which there are obligations on both sides, such as a premium account where the accountholder pays a fee and the service provider continues providing access to the service, is assignable in a bankruptcy, even if the contract itself says it's not assignable.

There's a few other bankruptcy principles at play, but that's the main one that jumps out at me.

There's also a classic case where the bankruptcy trustee can sell a bankruptcy debtor's Pittsburgh Steelers season tickets, including the right to renew for the next year on the same terms as all other season tickets holders. Just because the season tickets are revocable by contract doesn't mean that the team has the right to exercise that revocation against a bankruptcy debtor just because they don't like what's happening in the bankruptcy.

Oh, he knows. They took him on an airplane and made him eat food he had just called "poison" for a photo shoot.

He couldn't say no, because of the implication.

The "what is a bank" question is complicated, so "fintechs" have been operating in areas that are in some gray areas in between "definitely a bank" versus "definitely not a bank."

At the most informal, you've got things like a roommate who collects everyone's fair share of rent before sending one payment to the landlord, or a parent who keeps track of their kids' virtual balances of what the kids are allowed to spend. These definitely aren't banks.

Then you've got things like short term balances between people who deal with each other: an employer who keeps track of hours and pays the employee at the end of the pay period, a retail customer who has some store credit from a returned item, a contractor who periodically invoices a customer for work performed, etc. Despite the "credit" and "balances," these aren't bank accounts.

Some gray areas get a little bit more complicated. You have airline mileage and hotel point programs where the miles/points can be used to purchase goods and services, including sometimes those not even being offered by the business where the miles were accumulated.

Then you get into banking-like structures that might be, or might not be banks. Is it banking when you buy something on a periodic payment plan? What about when you put down a deposit to reserve a preorder for something you expect to buy when that product is released? Or give someone a gift card for a specific store? Does it matter if these programs are administered by third parties separate from the buyer or seller?

Even things like Apple Cash or PayPal or Venmo or CashApp perform functions that can be bank-like, or not really bank-like.

Fintechs have looked at the constantly updated rules of what they can or can't do before needing to comply with certain banking regulations, and usually try to avoid accidentally triggering certain rules. And the rules don't divide into just bank versus not bank, as many of the rules apply to non-banks that do certain things, and many of the rules don't apply to even banks that stay out of certain product lines. So it's not a binary yes or no, but a series of complicated areas where some are yes and some are no.

The big problem, where this Synapse bankruptcy is hurting people, is when people worked with an entity that provides certain services, who relied on the back end on a middleman that provides other services, and then the middleman fails. People operating in the gray areas are exposing themselves to systemic risks they might not fully understand.

This isn't about shareholders being wiped out. It's about account holders of what they thought were bank accounts losing everything because their accounts were powered on the back end by a company they'd never heard of or directly dealt with.

Several states have rules that the mail-in ballots have to be dropped in the mail on election day, and the mail can take a few days to be received, confirmed as eligible/valid, and then counted.

Many states have rules that allow for people to submit provisional ballots to be submitted and set aside while the system verified that the voter is eligible, and they don't actually unseal and count the ballot until they confirm the voter's eligibility.

Some even have rules where if a ballot is going to be challenged for not meeting the criteria for voting, such as matching the voter's signature on file, the voter is given an opportunity to cure the defect. This can take weeks.

Significantly, the largest state, California, does all of these. They do 100% absentee voting, which increases the administrative overhead of counting (each envelope must be validated before being opened, many ballots not received by election day, a long process for disqualifying or curing ballots). So they're the slowest. And they have the most. But they also have high voter participation rates, which is the goal of these voter-friendly policies that slow down counting.

These are supposed to have AI facial recognition for matching to government issued IDs, which just sounds like a huge attack surface (or even unintentional bugs).

Cigarette vending machines used to be quite common. Even today, there are some alcohol vending machines in controlled areas (some fancy hotels have 24/7 vending machines stocked with a particular brand of champagne bottles).

According to Wikipedia, about 155.5 million people voted in 2020 and so far, there are about 150.2 votes counted this time (98% of votes counted).

These numbers exclude third parties and independents.

When those are included, 2020 included 158.4 million votes, and the current count so far in 2024 is about 153 million.

Less than 150 million voters in 2024.

It's more than 150 million. The current count is about 153 million, and there's still more left to count in California.

The Republican party is ripe for conspiracy theory targets.

Epstein had close ties with Trump and his attorney general Bill Barr (whose father hired Epstein to teach at a prestigious private high school without a college degree, where he was known for ogling the high school girls and showing up to parties where underage drinking was happening). The waitresses and hostesses at Trump's Mar a Lago were also regularly recruited to work at Epstein's island. Alex Acosta, the federal prosecutor who agreed to a secret plea deal where Epstein served a slap on the wrist in a local jail instead of real prison was later elevated to Trump's cabinet, as Labor Secretary.

Now, Trump has named another child sex trafficker as his nominee for Attorney General.

There are suspicious ties between the Saudi royal family and key members in Trump's orbit, including his son in law Jared Kushner. Elon Musk has been doing sketchy shit with the Saudis and the Russians, as well. Basically everyone in Trump's circle, including his nominee to be the director of national intelligence, has shady ties with foreign adversaries.

There's lots of other little things about financial profiteering by the Trump folks: an SBA COVID bailout that went to huge businesses, a move to privatize or sabotage the public postal service and the weather service to help the private competition, arbitrary or politically motivated regulations to help certain businesses while hurting others, etc.

I mean, it really wouldn't be hard.

Yeah, the IRA and Infrastructure Bill steer about $67 billion to railways, $80 billion to transit systems. And even though a lot of the other spending goes towards the status quo of car-based passenger transportation, electrifying that will go a long way towards reducing carbon emissions.

And there are some more ambitious ideas baked in, too: redesigning cities to require less car infrastructure and overall energy use, etc.

I thought it was a big deal when passed and honestly can't understand why people who care about climate don't acknowledge just how big of a deal it was (and how devastating that so much of the money authorized will now be in control of a Trump administration).
