The point of the Robotaxi use case is it presents a very high duty cycle (multiple full charges per day) but with lower maximum range constraints.

So it’s particularly well suited for a chemistry which provides slightly lower density trade-off for double the total lifetime cycles. Similarly for EV buses and trucks.

Better chemistry at lower cost benefits passenger cars but also public transit and grid storage. It’s a multi-hundred-billion if not trillion dollar market overall.

It has nothing particularly to do with “Musk-moonshot” other than Tesla hyping and accelerating the pace of EV mass adoption, which drives a virtuous cycle for battery chemistry investment.
The vinyl groove is about 25-100 micrometer, and feature sizes on it go down to about 22.5 micrometer [1]. Lasers are extremely cheap today compared to what they were back in the day, and doing laser interferometry to detect features this small is not that difficult. I imagine a hobbyist with the right skill set could hack together a reader for a few hundred bucks at most.

You would think so from the outside but given the current level of technological development today's billionaires would be nothing without us, IT people (I include here everything from devops, to programmers to QA etc etc), without some lawyers and some medical professionals. Even the billionaires' goons are almost nothing without the technological-heavy guns they employ to potentially carry out their goon-related stuff, and said technology depends, like I said, on us, IT people.

It appears that we have already given up. Efficient, low-carbon-emitting natural gas power plants have been replacing coal-fired plants in the USA, largely due to cheap and abundant fuel extracted via fracking. If that were important, we would not be discussing bans on fracking.

> Actually it's not as much as enemies of India. I have seen fairly negative comments about India's accomplishments from neutral folks.

There is quite a bit of historical precedent for this. Indology, which feeds S-Asian reporting and popular knowledge about India, has historically been responsible for both anti-Semitism (etymologies of 'Arya', 'Swastika', should give you a clue), and also for widespread anti-Hinduism. It's not surprising that similar propaganda (as anti-Semitism) tactics are the outcomes of a flawed, ideologically motivated field of study, that has failed to reflect upon its sordid history [1][2].

Its effects are also not just limited to 'white' Europeans; the outcomes are easily visible in 'independent' India itself - the constitution of India, for instance, explicitly denies Hindus constitutional religious freedoms, in order to allow the state a free hand for 'religious reform'. This has led to widespread state capture of temple wealth, destruction of tradition, and widespread cultural genocide - something which no USCIRF or Pew report will talk about [3].

Neutral commentators, sadly, cannot be expected to be familiar with anything other than orthodoxy; the part of their self relating to India has not been challenged yet, as it was after the anti-Semitic pogroms. Sadly, there is no awareness of epistemic uncertainties, either in Humanities, or amongst its jingoistic practitioners, and is perhaps reflective of why some knowledge of probability and philosophy is crucial for everyone.

The answer in this case does not even satisfy that standard.

I think the problem with Haskell are not the concepts per se, but rather the terrible ergonomics (too many cryptic operators, point-free syntax, language extensions) and TERRIBLE learning material.

Monads, for instance, are hard to invent but are easier to use than most libraries. Most people won't come up with Monads and will only consume them. But books and Monad tutorials focus instead on explaining what they are and how they were invented. This is unnecessary.

Another problem is that the coolest things (monads, lenses, syntax extensions) are bolt-on, rather than built-in. So we compromise syntax (and sometimes consistency) in the name of extensibility. Such fundamental things should be in the StdLib. This is the same problem Javascript suffers from.

I strongly believe that a new language with the same semantics but a more approachable syntax and better learning materials (like Python) would be way more successful. Maybe that's OCaml but I'm not too experienced in it.

A completely analog laser scanning solution is entirely practical. There's no reason to sample it digitally.

But honestly, this seems like insane overkill. Vinyl has a ridiculously limited dynamic range, and digital recording at 24/48 is practically transparent even with low-end prosumer equipment. At the high end you have to work quite hard to spend more than $4k on a spectacularly clean and neutral studio-grade ADC/DAC. (You can spend more on madly expensive super-fi, but it's not going to sound any cleaner than a good Burl, Lynx, or Metric box.)

So if you spend $4000 on the turntable/arm/pickup another $4000 on studio grade converters, you can capture recordings that will be absolutely indistinguishable from the vinyl source. And your precious plastic disks can stay in their wrappers.

Pay the professor more money. Top Universities are sitting on tens of billions of dollars of endowments, and are willing to pay football and basketball coaches millions of dollars. They are not insulated from market pricing.

In many cases, a new assistant professor's salary at a top university is lower than than entry level salaries for software engineers in technology. For considerably higher stress, harder work conditions, and less job security until they make tenure.

Compare this with medical doctors at teaching med schools: they are often paid slightly less or competitive with practicing doctors.

Just performed several trials on my OnePlus 6T. It took 4, 14, 1, 1, 5, 3, 8, 4, 19, and 24 seconds for an average of 8.3 seconds over 10 trials. That's more than comparable to the time it takes me to solve one of Google's monstrosities.
What's the point of buying it back, if he can just start another similar company and siphon off many active, disgruntled users? Yeah, you don't get to keep the already registered userbase, or the brand, but I think former users would flock to it if they knew the original people were in charge of this product.

Candidate buyers:

1. Ragers. Not known for their apologies. So screw them. They don't need another tool to communicate their rage.

2. Recipients of rage. Is this so they can offer an apology? Surely nobody believes they need to apologize for their driving frequently enough to buy and install such a device. And if they want to respond to the rager with a plausible defense message, well, that's not going to quell a rager!

3. Those who want to broadcast an undirected opinion. Mod the device to bypass the 50 sanitized preset messages and you can show everyone your political beliefs, meme, or pithy quote. So basically dynamic LED bumper stickers. Free speech, fine, but more distraction. Yawn.
Which 3 white keys? There is a half-step difference between C through E, and D through F, even though both are 3 white key distances. The half step from B to C and E to F ensures that "3 white keys" can not be represented as a single distance.

A half step of a single note (specifically, the 3rd white key spoken of in this keyboard analogy) is all it takes to turn a major chord or scale into a minor one, so it isn't insignificant.
It should be Opt-In.

To stay sane of course. Dying from climate change isn't that different from dying of old age. If every day you remind yourself that you are going to die one day then you are putting yourself under mental stress. If it is hopeless as the title implies and there is nothing you can do to stop it, then thinking about climate change will just make your life worse than it already is.

I'm actually optimistic that it's possible to prevent the worst effects of climate change from a technological standpoint but I have no hope that we can resolve the prisoners dilemma. Making a quick buck is simply too easy.
That seems rather biased, Dan. While the 'daily reminder' bit is snarky dismissing it as mere flamebait or soganeering is unjustified and veers into trying to control the discussion. It's quite relevant considering the context.

There are measures we can take against climate change, they just go against the structural needs of the capitalist system. If governments continue to put the continuation of the system above the needs of the environment, then of course we won't see serious action. The author accepts that this is a permanent state of affairs and attributes it incorrectly to "human nature" when in reality it reflects the present weakness of the anti-capitalist movement. There is hope, but it's not in liberal politicians and eco startups, and I get why you'd be hopeless if that's where you're looking for change to come from.
This sounds like a really bad experience. Another completely different team and manager may be a day and night difference. For example there are many Google projects that work directly in open-source being led by folks that are the top of the given field, so worth checking out.

But yea, things are not always rosy and maybe Google indeed isn't the right fit.
Me: "I am selling this product that does X very well"
Prospect: "Does it do Y and Z?. If it can do Y and Z, I will buy it"

Y and Z is different for each and every client. That's how products becomes bloated. It is demand from real world clients that demands features to be added before they can buy your product.
Nothing here indicates a discharge rate. I'm having trouble finding the actual wattage produced by these cells over the 6 hour discharge time. Also, 6 hours is a longer than the current Tesla will run full charge at highway speeds (350 mile range, 75 mph ~= 4.5 hours). Plus, the current tesla can be re-charged and continue to operate, conditions I don't see mentioned.

If it is similar to existing batteries though... great!
Did you read the article? That's not what it's about at all. The author is saying that we aren't going to "stop" climate change. So instead we should be strategizing how to proactively invest in systems (both natural and man-made) to make them more resilient in the face of changes to come.
What if we replaced reliance on giant corporations with an actually efficient free market in software, content and services?

GitHub/npm (centralized) has been the closest so far for software, and the Web (decentralized) has been the closest for content. But what if we could go further and implement XANADU 2020?

We would at minimum need a globally distributed utility token to allow value transfers without needing to mess around with merchant accounts and international payments.

Here is a progressively more detailed architecture of what something like that would look on a large scale:

If you read it, please share your thoughts and feedback - whether you like some things or would want improvements in other things. Especially interested in whether there is something we missed and the system absolutely won’t work (eg why would companies pay for open source software if they can just clone it and even distribute their fork and have their fork compete with it.)

The most important thing I learned there was that you hire and promote people not so management can tell them what to do, but so they can tell management what to do. I didn’t even realize it at the time but the first post-Google job I had there was some clueless manager trying to set the roadmap and I was like “LOL what is this guy’s problem?” That when I started noticing the reasons that Google succeeds.
Would this be a correct summary of the paper?

1) eliminates Cobalt

2) improves energy density (more range)

3) faster charge rate

4) less SOC (state of charge) swing, meaning less cost & weight

4) 5x longer lifespan
Sort of, but if (and only if) you know what a regular expression formally means, you can disambiguate the equivocation introduced by ambiguous usage.
Jobs program.

It’s either that or keep building cities for no one.

Let me clarify one thing though, I don’t believe they want to assert a global hegemony, but under US pressure they might feel they have no choice but to try to counterbalance us. That would theoretically lead us back to a bipolar world where the PRC takes the place of the USSR.

Here’s the problem with that theory though. No one is taking Russia’s place, and Russia has more nukes and more domestic issues which is saying something. The PRC nuclear arsenal isn’t comparable to the USA’s nuclear arsenal, and the Japanese while not a declared nuclear power, have the capability to be a nuclear power in very short order. So no one is taking the USA’s place either, least of all China under any government when they’re flanked by: Russia, Japan, India, Pakistan, and for an extra dose of fun, an Afghanistan which will soon be back under the Taliban, officially.

At the end of the Cold War, the difference between the #1 and #2 economy was so great that it wasn’t even close. Right now our closest competitors have even more problems than we do, and we went ahead and exhausted a lot of strength and political will to act on the foreign stage fighting in Iraq and Afghanistan. Right now the President of the United States is making peace with the bloody Taliban! After 17 years of trying to replace them with a different government.

It doesn’t make sense for the PRC to build the New Silk Road of their primary policy objectives had anything to do with foreign policy. Any benefits at all to their foreign policy is the gravy to their meat and potatoes of what is the largest domestic jobs program in the world and the infrastructure to strip mine Africa and Central Asia of their natural resources.

Hegemony is what you get when you are the dominant power at the table by a country mile, several country miles really. What they’re doing with the Silk Road is some new form of colonialism we haven’t exactly seen before, but it still reeks of colonialism. It puts them in a nicer position than they might otherwise be, but those contracts with Kenya or Sri Lanka are only as good as the PRC’s ability to enforce them. Given they don’t have the airlift power or a Navy remotely close to the US, that’s a pretty remote possibility. They might as well invade Afghanistan for all the good that has even done anybody, but at least it’s a next door neighbor and not past Taiwan, Singapore and across the Indian Ocean.

No wonder they want US out of “their” neighborhood. In the mean time, it is a very nice jobs program, and it keeps the peoples happy, happy enough to not revolt, even provides a decent source of pride so they can say “we’re out their physically connecting the world while ya’ll are out there talking a good game on free trade and you know, enforcing clear shipping routes and whatnot.”

Maybe the market really is decent at figuring out where and what kinds of railroads should be built, because a railroad to nowhere still goes nowhere.
There are many ways to prepare for climate catastrophe, but here's one you could try:
1) Read Paul Ehrlich's book "The Population Bomb". If you don't have time, just watch the movie "Soylent Green" to get the gist of it.
2) Look around you for any sign of planet-wide famine.
3) ???
4) Profit!

It's bigger than that IMO. I can switch managers at a big company. But if the entire division is inept, it's time to jump companies because it's a tell that the culture is decaying.

For me, the only reason I will never go back to GOOG is blind allocation. IMO that's a bug, not a feature.
Exactly. And this practice is widely followed by basically every BEV car manufacturer. Most of the more recent models even have a bigger battery than specified, and charge only up to 90-95% capacity while providing the specified range.
You're applying the logic of perfect competition(which presupposes total market knowledge) to real-world consumer decisions, which are subject to multiple complicating factors from the paradox of choice to well-documented behavioral quirks.

I’ve been thinking lately that starting a commune might be one way. Think about this: a commune counts as a nonprofit entity. So you don’t have to pay taxes. If you own your land, there is no rent. The commune can run a business, and there’s no payroll tax and no boss, so all the profits can directly be spent on food and supplies. So you can live super cheap. You can have a little fleet of cars and bicycles, free for use, other facilities- and now, you’re not going to lose your job, you’re not going to become homeless because of a medical bill, when things go south you have mutual defense and support. Sounds better than going it alone, doesn’t it?
