I've read numerous analyses arguing that a small to mid size EV releases less CO2 and other pollution than a similarly sized typical gas car (or even a hybrid) even if the electricity comes from 100% coal.

Coal releases the most CO2 per unit energy. It's almost pure carbon after all. But to compare with a gasoline car you have to consider:

(1) Large power plants are anywhere from 1.5X to 3X more thermally efficient than a small piston engine. How much better depends on whether the power plant is an old school boiler and turbine or a newer supercritical steam or combined cycle plant.

(2) Gasoline is the highly refined and quality controlled end product of a long supply chain. Oil must be drilled, sometimes cracked (for heavy oil), shipped (often more than once), refined (this uses a lot of power), doped with small amounts of manufactured additives, then shipped at least one and sometimes two or three more times to a gas station. Every step of that supply chain uses even more energy, and this must be subtracted to get the overall end-to-end efficiency of a car engine. This makes car engine efficiency from oil well to tailpipe really suck. Coal meanwhile is often shipped only once or twice and requires minimal processing, usually just pulverization and then flue gas scrubbers at the exhaust end.

(3) ICE cars require a lot more maintenance and fluids that have to be changed, etc., and all that has to also be considered in their energy footprint.

EVs are superior in every single way except range and recharge time: complexity of the vehicle, reliability, acceleration and driving experience, urban pollution, overall emissions, and end to end efficiency. They remain superior even in the worst case of a 100% coal fired power grid, and very few regions get their power from only coal. The range and recharge time gap is already small enough to make EVs practical for 90%+ of driving scenarios and the gap is closing. The oil age is over.
>Do we want a society where we cut down the number of male engineering students to match the number of women? Or where we allow women into the course who didn't pass the same standard?

This is precisely what they want.
As a fellow European, I globally agree with you on this matter. However I think some of your assertions are weakening your post.

First things first

> why the US even recognises such a thing as race. To start with, it’s hard to define precisely.

Well this argument is pretty disturbing… besides the tiny and very neat island of abstract and platonic constructs every concepts about the real world are fuzzy. If someone followed your idea completely he could not use such concepts as “green” or “blue”, or even more relevantly, such an argument could also be applied to the concept of “species”.

> is your university really going to be diverse from simply having people with different skin color

I also find this assertion… strange to say the least. The clusters known as “races” cover phenotypical differences that are far wider than just “a different skin tone”. A black albino has a white skin, however no one will ever call him white. I am pretty sure that you could yourself instantly tell apart a black albino from a white just using unconsciously the craniofacial differences. It has also been argued that some of those biological differences could lead to behavioural differences and so give rise to another “default” mental representation of the world. So, even if two students come from the same cultural background, one could argue that their ethno-racial differences help to bring different points of views.

Even if I agree with you on the argument of fairness, the previous points are not at all effective counter-arguments against racial quotas.
You do: those millions are individuals. (And anyway, this was not the point - which still was with individual awareness and choice.)

BTW:

> I don't have any influence ... It would be the height of arrogance

With this you have been convincing: you really must be lazy as you say, pal :)
Add 50 more - to reduce hash rate even more. Announce hard fork right after difficulty adjustment. And then, suddenly, these who have not forked will be stalled for several weeks. Instead of 10 minutes per block, the time will be 30 minutes and possibly more. And to adjust the difficulty those who have not forked would need... a hard fork?

Yes, these 100 miners are pools. But where pool participants will go then? Will pools who have not forked keep pool participation fees low?

Etc.

The game here is not quite simple. It is much more complex than appears at first sight.
Something about the economics of lithium, and other recently important minerals confuses me.

How is a $1.5bn deposit, a major, significant source? That's would be about 10 days worth of oil. The whole global lithium market is just $3bn-$4bn pa. The rare earth market is about $2.5bn annually. Seems super low, relative to headlines/concerns/etc.

How are these materials simultaneously of such importance, and also so economically minor. What am I missing here?

> That leaves the question of crypto; given its oppositional nature to the current paradigm — decentralization, encryption, and ownership — it is clearly something completely new; moreover, the capital chasing returns in crypto is clearly financial capital, not production capital.

> That suggests that crypto will continue to exist in a bit of a parallel universe, which makes sense; it already has its own currencies, after all. That is another way of saying I think that crypto is still very early in its lifecycle; 2017 wasn’t the big crash, nor will the next one be — remember that tech had its own internal boom-and-bust cycles in the three decades between the introduction of the Intel processor and the Dotcom bubble. Nor is this a bearish take: those three decades were exceptionally profitable for everyone involved — including Sequoia, which was founded in 1972. Perhaps its successor, the one that shifts to providing productive capital for crypto companies decades from now, has already been born.
In the book named Binding Time, Mark Halpern wrote of Backus's Turing Award lecture ("Can Programming Be Liberated From the Von Neumann Style")that Backus seemed to be embarrassed that a computer worked by changing its internal states.

My girlfriend didn't read the book, but liked the movie a lot. "Finally a movie that takes its time to show as a different world instead of taking it as a backdrop of the same stories", she said. And I am with her. I like movies that just want to take me to a place instead of firing me up emotionally with cheap tricks while using the scenario as an exchangable backdrop.

I think the perspective that a role model has to be from your ethnicity or needs to look like you is not correct. Especially for young kids.

Not from the US but I believe the current disadvantages are still felt because the civil rights movement wasn't that long ago. Such inequality takes decades to vanish, IF policies actually do address inequality at all. Currently most countries face an increase in inequality.

You can fight fire with fire, but I don't think this applies to racism for numerous other reasons. Such policies even underline an alleged difference between black and white people.

There are also cases where multiple VCS tools are used or where you might want to build from an archived full copy of source+vendored dependencies and might not even have an underlying VCS to speak of.

Reproducible releases should probably _not_ have these commit metadata built in (e.g. imagine reproducible building this 5 years in the future where you've moved off git). Though this is quite useful in debug builds where you might be have installed a number of different builds in the wild and want to be able to quickly figure out the exact version of the code a given binary was generated from.
For what it’s worth you don’t need a mining expert to know that establishing a large scale mining operation will fuck up the local region somewhat.

At the very least, all the demolition and vehicles, fuel, explosives, chemicals.

It’s a no-brainer. Maine is not in the middle of some desert.
Interesting. 1,250 students surveyed and of those 437 were male, 813 female (if I have done my simultaneous equation correctly). Why the discrepancy? - Are white males currently less represented than white females on the surveyed campuses in the USA?

There is probably room here for the stats to vary widely by campus surveyed, potentially even across courses within a single college.

According to Kahneman (Thinking Fast and Slow), sample deficiencies are one of the biggest causes of incorrect deductions. Are there other surveys for comparison?
They got strict in the last month; now if you can't present a pass you might even be refused your salary. There have been demonstrations about this, as you might expect.

I agree that the tracing this summer was less than perfunctory, my brother had your same experience (his girlfriend wasn't even "declared", and nobody checked), and there was no Green Pass at all. Everyone wanted the tourists back so badly that the overall approach was to basically tick checkboxes and leave it at that. They got serious when it became clear the virus would be around all winter because of the Delta variant.

To be pedantic, the world is not mutable, rather, it is a process undergoing a continuous transformation.

Also, machines deal with data - which is encoded information about the world.

So when we say that a thing 'changes' in the world, what we're actually saying is that at time T, something happens to the world and from then on, the data we read back is different.

'Something happened' is new information which is added on top of the state of the world at time T-1.

Eg. the user e-mail does not 'change' to be come X, but rather, it used to be Y, then the user changed it to X on 1st of May.

So we can generalize that the world is a function `f` of some state combined with extra data of what happened at time T, giving us the state at T.
okay, then you’re thinking of Fraternal Orders, which is also something different. I’m aware of what “fraternity” means etymologically, but I’m sure you’re aware that etymology is separate from meaning.

We don't even have to argue anyway. From a dictionary:

> [treated as singular or plural] a group of people sharing a common profession or interests: e.g. “members of the hunting fraternity”.

Frankly it’s very easy to google.
Suppose 150k mile car that averages 30mpg. That is 5,000 gallons of fuel weighing 30,000 pounds. The amount of crude to make that oil varies, so actual oil you have to extract and ship and refine will be a bit more than that, and the refinement process is also dirty.

So compare that 30,000 lbs of oil to the amount of lithium in a Tesla battery pack, which is about 138lbs. 138lbs < 30,000lbs

Then figure in that those 30,000lbs of oil all go into the air producing not only c02 which is changing our climate, but particulates which are bad for our health and cognitive function, vs the lithium in a battery pack which can be recycled and/or re-used

This seemm like a large net win to me.

All of that said, yes, all of the resource extraction industry, from the iron and aluminum to the oil and lithium, has a bad history of responsible stewardship of the lands they exploit, and I support forcing them to do a better job.
No, you trust the majority of people running the code, not just miners: https://news.ycombinator.com/item?id=29012699.
One of my main selection criteria for a coding/terminal font is subjective quality of rendering and legibility at small sizes. The preview has an adjustable point size option but that isn't the whole story. The space taken up when rendered is what's important (i.e. pixel height of Em/line and/or the width of 80 monospaced characters.) Edit: A simple solution is to allow independent setting of Point size for the left and right previews so they can be visually the same size, rather than the same stated Pt.no.

Also missing one of my go-tos "Input Mono"[0]. What's great about it is that it comes with so many custom choices that you can configure specific character shapes and choose a width/weight that renders well for your particular use case.

I didn't read the book and really enjoyed the movie. Afterwards I didn't felt like there was a lot that happened in the movie, but that was not important. What I really enjoyed was the epic yet reduced aesthetics and the feel that this a bigger introduction to a hole new universe that could hold a lot of great stories. I'm thrilled for the following movies, but I don't really want to wait that long. So what I will be doing is start reading the books.

if the nodes don't upgrade their software to the code version with the commented line, they would reject those new blocks, regardless of it being the longest chain.

You would need to control the majority (of the important) nodes to be able to pull this off. If the nodes are incentivised to keep the limit, they will.
Can you go into detail as to how specifically it is not clean, and how it compares to the resource extraction of other things like steel, aluminum, oil, etc.
Very good point and this approach does afford a back-channel with plausible deniability.

After all - data held in a country is subject to the government of that country being able to demand/obtain access.

RESTful is ok for public APIs. If you design both the client and server, you don't need to be stateless.
Lithium is only created in stellar events (Big Bang, super novas). There’s no natural way for it form on Earth.

As a result all lithium deposits we’re created during the formation of the planet as it coalesced out of interstellar dust. Consequently the distribution of Lithium around the planet is pretty even. There’s no “hot spots” of high concentration, and every country has a supply proportional to its land mass.

That, plus the relative abundance of Lithium, means it’s unlikely that fighting a war for Lithium will ever make sense. Much easier and cheaper to just dig in your own backyard, than fight for someone’s backyard that has the same dirt in it.
I'm missing Iosevka.
If the UK is anything like the US the contractor would need to be UK citizens, servers in the UK in special data centers, and most, if not all, of the work would need to be done by UK citizens. There might be some very very high level talks with non UK citizens.

I am curious how it would work using the AWS tech that is probably built by a lot of non UK/US citizens. Maybe the UK will allow work done by US citizens.
> Somehow people have been convinced that it's better to work to build/maintain someone else's property instead of your own.

It is a bit strange, isn't it?

We've transitioned to having both parents work, but then we pay a large percentage of the extra income on child care, house upkeep (cleaning, repairs, improvements, etc), prepared food, etc. -- things that one parent could do if they were at home instead of working for someone else. It seems worse for the kids too, to have both parents working.

It doesn't have to be the mother by the way. But I also don't think the idea of a stay-at-home mom should be as condemned as it is, at least in certain circles. Women should absolutely have the choice to not be a stay-at-home mom, but it should be a choice without stigma attached either way.
Yeah with Dune you sortof just have to ignore the tech. It never makes much sense.

Later on the books get heavy into bio-engineering. Some really strange stuff in the books w/ clones (and multiples/generations of the same clones) etc. The film sorta hinted at it a bit with the spider creature thing (which is not in the original book) but...one of the distinct things about the Dune universe is anything "alien" is really just weird Human bio-engineering.
McDonald's is also enjoyable and enjoyed by millions, it's still not "good food"; as I always say, that sort of reasoning leads to us eating shit because billions of flies cannot be wrong (cit).

The best part of Dune is clearly the worldbuilding rather than the prose. Yes it can be used, and the software is great when you get to know how it works, but there is a learning curve that similar software does not have.

So much? Singapore's GDP per capita is $60k per year so $5k per month. If $2 month's worth of GDP for 1 baby so an entire lifetime of a new citizen is a lot, then I don't even know what to say.

> for something that used to come naturally through cultural forces, then it’s probably not sustainable

Having kids sucks (your mileage may vary, but before ~2-3 years the investment >>> benefits for all but the most dedicated people out there). Kids used to be cheap labor, which is now illegal for good reasons and they could be abused at will for various things, which is also illegal for good reasons. They were also frequently born because women didn't have a say in the matter, which is also becoming illegal for good reasons.

It is sustainable, it just needs to be done properly and respectfully.

Not by treating women like broodmares and kids as slaves to be worked to death and beaten up by adults who don't have any other way to relieve stress.

Can you sit back at the start of a pandemic and wait a year or two, and then slowly start pondering if a few million for a contact tracing app would be worth it?

We have also invested over $350 million in vaccine research and development."

But, seemingly, this one is "The richest known hard rock lithium deposit" so it's got to be worth something, at least it's newsworthy I guess.

Anyway, the article is not about the operation of mining lithium, how to earn money on lithium or even chemical processing, it's about regulation about mining in Maine, the deposit itself just being the driver of the story. It also goes into describing the supply chain around lithium and some other goodies.
I doubt even the MSM believes this. They are throwing stuff at the wall, seeing if something ever sticks. I guess it's the only way they can come up with to save their business.

You can. This is called anthropometry. Many measurements are highly correlated with race. Widely used in all sorts of situations. For example, in legal medicine it helps to identify bodies.
Yes, neither option may be perfect. But just claiming that, therefore, they are equally bad is philistine. It's a full embrace of a talking point even ExxonMobile has retired.
Thanks for the question. Differentiating in the LMS category is definitely not easy - there are many impressive solutions. I think our biggest difference is the way learners are activated in their learning. The ability to run guided peer reviews, discussions etc. If there is a specific product you are thinking of then I might be able to do a more accurate comparison.
