Nearly all of the purposes for these flywheels could equally be met with existing infrastructure with software only changes.

Solar inverters can produce/absorb reactive power easily - but while that can frequently be configured from the control panel of individual units, rarely is that ability exposed to grid operators.

Inverters at DC undersea links can do the same. As can some kinds of wind turbine.

All three can also absorb harmonic power and emit it as fundamental frequency power.

Battery energy storage systems can also do all of that, plus also provide 'simulated spinning reserve', and also provide brief huge increases in energy output to deal with various collapse conditions.

Wind can also do this (with caveats).

However, despite lots of 'green' energy sources having the necessary abilities, it frequently is lacking software support, particularly in the 'control plane'. Part of that is because there is no legal mandate to have these abilities, and there is (in most markets) no payment for providing this service. Therefore operators don't bother to enable these features.
From the article, "What I see is narcissism: a demand that art affirm us, never threaten us, never make us feel inadequate or ignorant or small, echo back to us our precious little selves."

A friend recently commented about the downside of "inclusivity" which we seem to be all about these days. If intelligence is a spectrum working to be more inclusive will always ONLY move us in one direction, down. The more "inclusive" society becomes the more boring it is.

How does the extended output work, and what's the point of extended output?

From what I can see, BLAKE3 has 256 bits of security, and extended output doesn't provide any extra security. In this case, what's the point of extended output over doing something like padding with 0-bits or extending by re-hashing the previous output and appending it to the previous output (eg, for 1024 bits, doing h(m) . h(h(m)) . h(h(h(m))) . h(h(h(h(m))))). Either way, you get 256 bits of security.

Is it just because the design of the hash makes it simple to do, so it's just offered as a consistent option for arbitrary output sizes where needed, or is there some greater purpose that I'm missing?
This paired with a TPMS scanner would be great for occupancy for the entire campus. Scan the TPMS at the major traffic zones, then compare with bluetooth signatures.
Thanks for the great references! I must say that I had never thought of such enumeration before. I'll be thinking about its potential use for a while.
Except the impact was totally predicted. Climate change, with more total energy in the atmosphere, increases the occurrence of extreme weather events - the lengths and severity of droughts, but also the severity of extreme flooding. The best example I've seen of this is portions of Australia: would have to search to find the source but a great quote was that over a ten or twenty year span they had totally average rainfall - it was just distributed with 9 years or something of extreme drought followed by intense floods.

It has long been known that drought is a major problem for the Panama Canal, and that climate change will increase the severity and occurrences of droughts. None of this is unexpected.
Texas is connected to Mexico and some other exceptions. The fed though would rather frozen dead Texans than deregulate and allow ERCOT to connect as they do to Mexico. Fed basically holding some of the poorer rural Texans hostage to influence some rich ERCOT bureaucrats to change their regulations -- pretty fucked up IMO.

There are lots of options. Most of what you see they don't: this is a one off project for the hacker and if others find it useful great, but not the goal. As such packaging isn't needed, sometimes you shove it in a box.

If you want something nice, that can be done, now you need to pay someone (could be yourself!) to design a package. ESP32 is designed to be easy to put into your own products, this means design a circuit board and case to fit each other, and so on. Then you buy the ESP32 chips in bulk and assemble them onto the circuit board. The board you buy for a prototype is officially only a reference board and not what they expect you to ship (though shipping the board is common: they are small, cheap, and someone else did the hard board design)

Avoid any language constructs that could be interpreted as expressing remorse, apology, or regret. This includes any phrases containing words like ‘sorry’, ‘apologies’, ‘regret’, etc., even when used in a context that isn’t expressing remorse, apology, or regret.
If events or information are beyond your scope or knowledge cutoff date, provide a response stating ‘I don’t know’ without elaborating on why the information is unavailable.
Refrain from disclaimers about you not being a professional or expert.
Keep responses unique and free of repetition.
Never suggest seeking information from elsewhere.
Always focus on the key points in my questions to determine my intent.
Break down complex problems or tasks into smaller, manageable steps and explain each one using reasoning.
Provide multiple perspectives or solutions.
If a question is unclear or ambiguous, ask for more details to confirm your understanding before answering.
Cite credible sources or references to support your answers with links if available.
If a mistake is made in a previous response, recognize and correct it.
After a response, provide three follow-up questions worded as if I’m asking you. Format in bold as Q1, Q2, and Q3. Place two line breaks (“\n”) before and after each question for spacing. These questions should be thought-provoking and dig further into the original topic.

Considering it's Boeing, there's a 50-50 chance that the leaked parts data is a shambling pile of DFARS violations.

They can get up to some stuff when it comes to classifying things as "new". Check out the financials. BGS is always swimming in money compared to the other divisions - that cash flow almost certainly helped along by pushing returned assemblies back out as "more new than they probably actually are, and should be according to the contract docs".

And there's just a joyous brown fountain of horse puckey when it comes to "equivalence", a whole other pile of dead fish. The stuff that the PLs claim is "electromechanically equivalent" makes my brain hurt. Like, does it have wires sticking out? "Oh, that's an ARINC 600 connector for sure!". It's harder to nail someone for false equivalence, though, since it's a pretty nebulous thing to define. Unlike "yo, this new part is actually old and busted".

I should add that Boeing isn't really alone here. Lot of suppliers do this stuff too, and Boeing, the damn fools, probably get caught covering for suppliers and subsidiaries.
I would like to to state a very specific thing: I’m both a socialist and fine with price gouging for tesla trucks, and I don’t feel that’s a hypocritical thought.

Not all “things” are equal though. When we’re talking about materials required for living being hoarded, I’ll be right there with you. When luxury automobiles and tickets to Taylor Swift are the topic, I’m fine with the market deciding.
Modern super container ships can hold 24,000 containers each of which is 20ft long.

If you were to line these up end to end it would be 96 miles long.

The Panama Canal is only 50 miles long.

You could do it but the entire length of the track would be completely full of containers twice over.

I somehow feel it would not be cost effective in the long run.
This would be awesome. Do a weekly/biweekly/monthly poll on different topics and adding the top voted entries to the list? Doesn't just have to be programming or science either, there've been some great threads with recommendations for music courses and lectures.

I don't see how you can really get a decent grasp of quantum with an undergrad. The standard American physics curriculum has some quantum in sophomore year with Modern Physics, and then Quantum in Junior/Senior year. But you can't exactly skip mechanics, E&M and all of the mathematics (Calc 1-3, Diff EQ, Partial Diff EQ, Linear Algebra) you need a background in. So you pretty much need 2 years of prep to really start learning. Even if you add some specific technology courses around the engineering, how do you get around this undergraduate program not being a Physics or Applied Physics degree, without throwing the baby out with the bathwater?
In the absence of the canal, did these lakes naturally drain to the sea, or are they in some sort of natural "bowl" that is higher than sea level?
> The fact that there are problems with an alternative set up (oh no, unstable populism!) doesn’t mean the current paradigm is itself flawless.

You're absolutely technically correct. In the same vain, this doesn't mean that there's any better alternative.

> the artifacts the rich and powerful put in place to ensure they and their friends and family stay rich and powerful for as long as possible

You could say the same about many other things that benefit society as a whole. Turns out, things that make society rich and stable often help those in power stay in power.

> Move fast and break things, especially governments.

Unfortunately, I've been on the internet too long to be 100% sure it's sarcasm. So, just in case — please don't break governments. And may be don't actually move fast with them. Thank you.
JLCPCB would 3d print high-quality enclosures from a variety of UV resins: https://3d.jlcpcb.com/ and decently cheap.

The next best option is injection molding with PCBWay (or other similar provider): https://www.pcbway.com/rapid-prototyping/manufacture/?type=4...

An alternative is a sheet metal enclosure: https://www.pcbway.com/rapid-prototyping/manufacture/?type=4...

But 3d printing with JLCPCB is really the most convenient way unless you need a lot of parts (thousands) or the material properties of the UV resins would not be enough (high-temperature, outdoors, etc).
Photons are the means for transfer for all energy sources at some level, so using that as a comparison for the actual generation method seems a little pointless.
I dream of Linux someday having a stable driver API. Would be a lot of work to accomplish (and an ongoing headache for the kernel maintainers), but ultimately worth it to no longer have these embarrassing and frequent breakages.

If BlackRock doesn't buy individual houses in the U.S., but does invest in multifamily, and apartment properties, then what kind of properties are "other residential"? Anything I can think of is either a kind of individual home (which they don't buy) or multi-unit.
I'm not really talking about producing something at scale, just the bare minimum of not having a board with wires coming out of it.

Say I want to do some one-off project and put it outside somewhere, out of the weather, with some batteries to power it.

Or an indoor thing with an AC hookup of some kind.

Doesn't have to be perfect or beautiful or as tiny as possible; just sort of a complete package.
That comment doesn’t really seem relevant to the question: it’s answering “why do you need freshwater for the canal when you have sea water”, but if I understood correctly, they asked “why is there less freshwater around when there’s more seawater?”
Because the locks were built where they were over 100 years ago without the need for any pumps since there was an existing lake. The number of pumps, installation time, and power needed to run the locks (in both directions since the middle is at the top) would be huge. I could still happen, but take a decade to build out.

The vertical rise is about 26meters and there are 3 10meter locks (33mx300m in size) in each direction. 40 ships travel through each day (~3ksec per fill bidirectional) and each fill is ~1Billion liters or 250Million gallons in less than an hour. Lifting 1B liters through 30m would need 100MW to power 100% efficient pumps continuously for leakless locks. The solar/hydro power of rain is significant.

Also, everything in the lake would die once it was contaminated with sea water, and you would be contaminating the Pacific with Atlantic water, vice versa, or both.
> Instead [of the Bohr model], Morello uses a real-world example in his teaching — a material called a quantum dot, which is used in some LEDs and in some television screens. “I can now teach quantum mechanics in a way that is far more engaging than the way I was taught quantum mechanics when I was an undergrad in the 1990s,” he says.

> Morello also teaches the mathematics behind quantum mechanics in a more computer-friendly way. His students learn to solve problems using matrices that they can represent using code written for the Python programming language, rather than conventional differential equations on paper.

Your source is slightly confused. The original design of the Apollo Guidance Computer used core-transistor logic and they built three prototypes 1A, 1B, and 3C in large racks. In 1962, they switched to integrated circuits and built rack-mounted IC prototypes (AGC3 and AGC4) using Fairchild Micrologic. They built the Block I AGC systems starting in 1963 and launched one on an unmanned flight in 1966. Block II planning started in 1963 with qualification tests in 1966. All crewed flights used Block II systems. Source: "Journey to the Moon" by Eldon Hall, designer of the AGC.

TL;DR: the core-transistor logic AGCs were prototypes before Block I; Block I used ICs. You can see a photo of a Block I module with flat-pack ICs here: https://www.computerhistory.org/revolution/digital-logic/12/...

This makes sense. As an auto manufacturer why would they sell a car for “money”? If I made cars I too would require money and a legally binding pledge to neither profit or cut losses on any purchases made from me. After all what is a truck but an NFT with wide panel gaps anyway?
What kind of cargo may be worth paying $4M to skip the line? I assume it should either be something that perishes if not delivered on time, or something extremely critical overall.
It's also a little more complicated than that. A lot of the water for the canal comes from Lake Alajuela, which was formed by damming the Chagres River. Because of deforestation and rapid erosion, the lake has been filling with silt and is no longer able to hold as much water as it used to. This is a problem that has been known for the last few decades, but very little has been done to address it.

This current problem is especially bad because the dry season normally begins 4-6 weeks from now and there will be little rainfall to re-fill Lake Alajuela (or the lake its water flows into, Gatun Lake, the backbone of the canal).

(I previously worked for the Smithsonian Tropical Research Institute in Panama and lived on an island in the Panama Canal)
Minimum wage should be enforced by implementing a tax that is relative to employee compensation. If you pay minimum wage, you pay maximum corporate tax (or a new tax), something like 49%. Every dollar/hr on average you raise reduces it by 5% until the min 5%. So, if avg compensation is +$8, tax is 9%. This assumes they will raise prices no matter what, the max tax can be lowered when they charge less. Basically force them to accept low profits or close down locations.

> Respecting your partner's executive choices and self-assigned preferences, and recognising that they follow motivations of their own, leads to relationship problems?

Not what I said, and quite unrelated.[1] Moreover, it is not what you said, even if that's what you meant. You said:

> She went to the time and trouble to pick out an umbrella especially for you, and she did it because this is clearly not the first time so it makes sense for there to be a spare umbrella.

These are significant assumptions to make. Jumping to conclusions like that will lead to relationship problems.

Of course, I could go on and talk about how the behavior could be problematic even if the assumptions are true, but it depends on the particulars of the two people involved. Certainly, if the assumption is true, the behavior is not necessarily a positive one. Intentions matter. As do outcomes. Don't ignore the latter.

[1] And yes, that could trivially lead to relationship problems, and could also trivially lead to relationship bliss, given how generic your comment is.

Lots of replies to this comment, but they all miss a critical detail: the Panama Canal isn't just a "man made river" at sea level, it's a series of locks that raise and lower the ships between the oceans, with stops at a few lakes along the way.

Ecology problems aside, you need water at the higher elevations to operate the locks, and the lacks have to retain enough water to remain navigable. It's not practical to pump that much water up hill, so we're at nature's mercy for the water supply.

If there isn't enough water in the system to operating the existing locks, there's no point adding a parallel set to draw from the same limited water supply.

The Ramcharger may have found the sweet spot until Solid State batteries rule the world. (ie when your phone stays charged for a month you will know we are there) Daily use - just use the powerful, quiet, smooth, instant 92 KwH battery to go up to 140 miles per day and then plug in at home each night to charge for about $8 (at 10 cents per KwH) MUCH less expensive than gasoline to go 140 miles (140/20mpg x 3.50 / gallon = $24) When Towing up to 14,000lbs (HD Territory) you will use the battery and the generator for exceptional range, power AND efficiency. 600 + HP and 600 +Torque. My estimate is that you will be able to tow approx. 300 miles in this mode with a very heavy trailer which is better than a 2023 Chevy 1500 w/ the 3.0 Duramax Diesel with much less power & Torque.
