Unfortunately, banning possession/distribution doesn't actually make things unavailable, so it fails to prevent this harm too... Though I suppose the knowledge that people are trying to track down and eliminate such content may help the victims in question.
i3 is very expensive, very sophisticatedly engineered, but also very shoddily engineered at the same time.

Despite using a full CFRP body, like that of supercars, mass savings were small.

It is also heavy because of tons of German luxury features that should have no place in an entry level vehicle.

It was also generically marketed on being "sporty" and "fun" to drive, while being one of the more morbid EV around, much like Chinese entry level EVs.

The design suffers from usage of enormous amount of unique, custom made parts and materials.

Basically it is an EV equivalent of Suzuki Mehran on performance and feel, but painted over to make it fit the "New Type Luxury EV" marketing concept.

It's also weird to see lots of "vices" (beer, cigarettes, condoms, etc) in vending machines on the street. Like, when I was in Italy I saw kids buying beer and cigarettes and no one seemed to care!
In my experience the main reason women don't end up in STEM fields is simply because they don't understand what steps to take or (more often) they haven't been exposed to the ideas at all.

Fundamentally (in the US at least) they're simply not shown compilers, CAD, electronics etc as high school students. The few women I met in college who went into engineering and CS did it because someone went out of their way to show them these things or their high school had a special elective program that had them play with the ideas.

If I where you I would show them some simple neat idea that can lead to more complex conversations (Cellular automata is one someone showed me and that ended up being the main component of my first non trivial program I wrote as a teenager. I'm not a woman but I'd imagine this is a human thing and not gender specific.) IMO too many kids are "held by kid gloves" and aren't given the languages and tools to participate in adult conversations so they can see some of the more amazing things in the world (again, for me this was the C programming language, for many other people it was math) If you can give them something interesting (physical or not) to take home and study on their own you'll probably change their lives.
That sounded interesting - until I saw in the paper that:

1 litre of LOHC => 2 kWh

Cool? Except:

1 litre of Petrol => 9.7 kWh

(according to this: https://greennav.wordpress.com/2008/03/03/how-much-energy-in...)

I don't know about the accuracy of it, but I found this:

https://afdc.energy.gov/fuels/fuel_comparison_chart.pdf

...and it says that 33.70 kWh of electricity is the equivalent of 1 gallon of gasoline; since 1 litre is about 0.26 gallons - that's close to the other number (off somewhat though; 8.76 kWh instead of 9.7 kWh).

Regardless - it all seems to point to that either the tanks in a car would need to be 4-6 times larger - or the engines have to change in some manner to deliver the same level of performance with less energy - or something like that. Probably a combination of both.

I'm making the assumption that the LOHC would be carried on-board the vehicle, as that seems (?) like it would be safer and easier than carrying around compressed hydrogen (embrittlement issues, migration issues, consumer aversion perhaps). I don't know, though, if LOHC is more or less dangerous for consumers to handle like gasoline, or if the dehydrogenation process can be done on-board a vehicle; the paper doesn't go into such detail. It does safe it is safe to store and transport via normal methods, so it sounds like it might be ok in that regard for consumers.

Heavy structural materials tend strongly toward local utilisation as transport costs are so prohibitive (water transport possibly excepted). Concrete companies are the canonical anti-monopoly-tending industrial sector example in many econ texts.[1]

So your objection is somewhat like claiming oxygen starvation by fire is impossible since the atmosphere as a whole is 20% oxygen. It's what's near you that matters, and the local impacts of sand and gravel mining are often severe. As the Nature article notes:

Desert sand grains are too smooth to be useful, and most of the angular sand that is suitable for industry comes from rivers (less than 1% of the world’s land).

Riparian ecosystems are generally the most productive of terrestrial (vs. marine) zones, and activities at one point on a river will have major impacts downstream and even offshore.[2]

It was mentioned later in that thread, but the Kona EV also lets you control the AC remotely via its mobile app without leaving the keys in the car. I don't know if it'll run indefinitely, though; my old Chevy Volt would turn off remotely started climate control after 15 minutes or so, and I haven't tried in the Kona yet.

That said, even if it is time-limited, 15 minutes is usually enough to cool down the car without leaving the AC on all day.
Yes! This is it. Thank you!
At the same time, from a driving perspective, the Model 3 systematically outclasses the experience of driving a 3-series. And not by a little. I like both but they are not comparable.

When your competitor has bested you on the primary function of your product; is perceived by consumers as way cooler than you; holds a decisive technology advantage in an area that is perceived as critical to the long-term survival of your product; and your only response is "better fit and finish" -- well, I think this is a very bad place for a luxury car manufacturer to be.

That is a strange delusion on several levels. It looks lik downright psychological projection of issues with fossil fuels - and the fact limited lifetime also applies more so to fuels and hydrogen especially even.

Batteries currently have better effective energy density than hydrogen ironically given how heavy the tanks need to be to contain the metal embrittling escape artist that is hydrogen. Yet the traditional auto manufacturers bizzarely seem to have decided to make hydrogen their hill to die on.

> [...] nearly every brand of ice cream in Europe became part of Unilever’s ugly “Heartbrand” in the late ‘90s. Now anywhere you go, you will just be offered the same Magnum, Solero, Cornetto

This is true, but a bit of an exaggeration.

In the UK and Scandinavia, many small dairies are producing nice ice creams which you can buy in regular supermarkets.

In fact, a favorite thing of mine is trying to find said ice creams without any gelling agents (carrageenan, gum, etc.) which are really harsh to gut biota. There are quite a few.

Obviously, Unilever's is not one of them.

The article mentions that CEOs make 300 times what the typical worker makes. Do they provide 300 times the value to the company? In most instances, I think probably not. However, I would say the amount of responsibility the CEO has is in excess of 300 times the average worker. That responsibility must be worth something, and I think this could justify fat paychecks even in noncompetitive markets.
There are some emerging platforms online for this, but shockingly the available mentors far outnumber the mentees.

> If you want nuclear, you want punitive carbon taxes

I think this is the crux of the issue. Carbon-emitting plants get a free pass on safety and long-term environmental costs, while for nuclear all those things are examined with a fine-tooth comb, then compared to the cost of alternatives without those things.

In any regulatory regime that punished carbon emission the same way it did nuclear waste, nuclear contamination, etc, then coal plants would be unthinkable.

I was going to say "then nuclear would be obvious", but I'll hold judgement there because I don't know how that would compare to other non-carbon-emitting sources (hydro, solar, etc).

The Curious Mystical Text Behind Marianne Williamson’s Presidential Bid
> Mostly I think Prof. Matloff is forgetting that base R is kinda terrible and no one else has done much about it aside from RStudio.

I think he'd disagree with the contention that base R is kinda terrible. Like, I'm pretty sure he's wrong. But this isn't something he's forgotten, it's something he's never believed.

The point about the Tidyverse and RStudio is that RStudio doesn't make any of its revenue from the Tidyverse. They distribute it free. There are no upsells for any of it -- I can't go out and buy ggplot2 add ons, I can't buy dplyr support contracts. There's no money to be made on the Tidyverse, and plenty of resources thrown at it.

So what is RStudio selling? They sell an IDE, they sell servers to host things built in R, they sell a package manager solution, they offer most of these things as a SaaS offering as well (although rstudio.cloud is still in trial and they haven't started charging yet).

In other words, RStudio offers tooling for people who write R. They don't really care what kind of R you're writing, from a financial perspective. They get paid the same if you're using RStudio to write stuff using data.table as they get paid if you use dplyr. RStudio is making a bet that more people will want to write R code if they make R a more pleasant language to work in. And anecdotally, they're absolutely right -- I tried to learn R before the Tidyverse, and I hated every moment of it. I like post-Tidyverse R (although I got into it when people still called it the Hadleyverse). I know several other people with similar experiences to mine.
I think this piece is misguided.

Some background: as a kid, my family boated on the SF Bay. I can remember when cormorants were rare on the bay. There were no porpoises or dolphins in the bay. It was rare for a whale to enter the bay. There were zero brown pelicans. All of those observations are entirely opposite of today's bay. Acts of government have seriously improved water ecosystems.

Now that memory is a data point of one. But we also all should know that the Cuyahoga has not caught fire in 50 years and that's not because of the work of zebra mussels -- they don't consume stuff which is volatile enough to catch fire spontaneously.

In summary, before reading the piece everyone should be aware that waterways have generally been substantially cleaned up in the last 50 years.

With that as background, I have immediate questions: What evidence is there that Erie was cleaned up by mussels and not by new environmental laws? Even if the mussels helped, were they a necessary condition to cleaning this up? Or did they simply advance the cleanup by a few years?

The piece contains good skeptical thinking, but it does not sufficiently lay evidence that Zebra Mussels were a cause of Erie's cleanup, rather than a coincidence. It's pretense at being a factual explanation of history is unearned.
With respect, its laughable to think that anyone working on big-data with R has _not_ heard of `data.table`. When your livelihood depends on it, you tend to find it out one way or the other.

However, I'd claim most folks don't deal with big data or even medium data! [Aside: I chuckled at the 1e5 columns on the plot]. Personally, at the small-to-medium range, all languages are fast enough. It boils down to ergonomics for me. I _detest_ the subscript notation. It slows me down -- not just productivity-wise but also how I read or reason-about my code. Not surprisingly, I prefer `dplyr` over `data.table` (base R or `pandas`)
This makes no sense at all.

First, if you have the ability to engineer a bioweapon like this and spread it around to eliminate cancer in humans, why wouldn't you just genetically engineer the humans to not have cancer (i.e., just bake the ability into people, instead of having an airborne agent which will have much less efficacy since not everyone will catch it)? And secondly, why would you want to give people the suffering that comes with colds?

So, that leaves 2 possibilities:
1) Cold viruses were engineered, but they evolved to their present state where they're actually a big nuisance rather than a big help, or

2) Cold viruses were just a natural evolutionary outcome.

Either way involves cold viruses getting to their present state through evolution (both ways being undesirable to humans), not engineering, and #2 satisfies Occam's Razor better because of what I wrote at the top (i.e., engineering contagious viruses to fix a problem in human biology is a Rube Goldberg-esque solution).

I guess if you really want to get wacky, you could postulate that in this ancient society, they had some sort of religion or philosophy that humans shouldn't be biologically "tampered with", so either most people or at least the authorities would have rejected a straightforward medical solution, so some rogue person or group came up with the virus scheme (somewhat similar to how we can't get everyone to actually update their software to fix security vulnerabilities).
Frankly there was just too much to learn - I remember being totally chuffed I had found a slimline xdm replacement with no dependency on Gnome / KDE and yeah it is good and it is lightweight and I knew where the source code was but ... even if I found a slim lightweight version of every thing on a modern desktop - well I could not even list all the components.

There is a some unix replacement project trying to rewrite major parts "simply". But in the end you just don't understand 90% of what is going on or you have a tiny tiny server.

It's like everything these days is npm - install one thing and suddenly you find there are 900 packages installed including left-pad-0.3.4
But we're going into this story already knowing that 81% were deemed innocent: already wiggled out.
In the meantime, maybe roll your windows down when you get in the car?
I suspect this is exactly it.

MSFT had a similar experience with HCL (I think it was them, one of the large Indian outsourcing firms in any case) when I was working on Vista. All fixes for bugs identified by static analyzers (PREfix/PREfast) were outsourced to contract programmers who had zero familiarity with the Windows source code. The “fixes” they sent back almost invariably introduced new bugs, and the whole back-and-forth process took much more time and effort (and presumably money) than just having the code owners fix the bugs in the first place.
#3 reminds me of self-serve retail checkout kiosks: when I get stuck, or the kiosk gets stuck, a nearby live human approaches and resolves the issue (except when there's no live human nearby in which case I just get to stand there feeling awkward and useless. it's pretty humbling.)
"If Amazon stops serving its customers well it'll go out of business. If it pisses people off it'll go out of business." This is the central myth of the free market. Part and parcel of a massive internet company is having control over the flow of information, how can people protect their rights if they don't even know they're being violated, or if they're being distracted from protecting themselves by lies and manipulation? That is essentially the stated goal of a company's PR, and the sort of technology that goes into actively manipulative practices that we just accept out of tradition (the entire concept of marketing is a violation of "invisible hand") has now reached the level where people stand no chance, the amount of money and research that goes into making you make decisions that are in a large corporation's interests over your own are something any particular individual could never possibly match.
Because they never market it seriously. Where I live, it was a challenge to try one, even harder to find a salesman that can sell you the car. Nearly nobody knows about that car.

It's the only car in the industry that took seriously sustainability. (Sustainable textile, recycled material, end of life reusability and recycling. etc.)

The efficiency is excellent, about 5kwh less per 100km than a tesla. It drives great, it's powerful, fun to drive. I haven't found a i3 owner that didn't like his car yet.

With the range extender it removed range anxiety without add long recharge time on a trip. (granted with more frequent stop)

I bought a used one last week. Maybe it's the honey moon, but it's the best car I have ever own, by far.

The lack of leadership from top executive made the car unpopular, not the car itself. This also led to a lot of employee turnover because the lack of seriousness about the i series.

This is well known.

Why do you think the strongest of the strong bacteria are found in hospitals? Because they do a lot of cleaning and disinfecting. The weak are purged, the few who remain don't have to compete with the weak on other axes, thus they can concentrate on developing resistance.

In your home, where you don't clean as strongly and as frequently, there is a wide variety of bacteria who compete against each other, and can't spend too much on developing resistance.
IMHO previous gen BMW models were stale. But all the new ones that came out in the recent 1-2 year have been good, including current gen 3 series.

My name is Sofia, I want to appreciate the great work of Dr.Isai, I was diagnose of herpes disease 2years ago, and I’ve loose all hope that there is no cure, but then I was taken medication from my doctor just to sustain myself until I got to know about Dr.Isai through a friend who he cured of HIV. I contacted him and he sent me a Herbal Medicine which I took as prescribed for some Weeks. After consuming the Herbal medicine i went for checkup at the hospital Which I was confirmed Herpes Negative after 2 years of being positive, it is indeed a miracle, Dr.Isai is a great man, if you have any issue you can contact him on this Email: drisaiherbalcenter@gmail.com or you whatsapp him on his Number +2349034352176. While I was on his medication I understood that he can also cure HIV/AIDS, ASEPSIS, CANCER, warts, Miscarriage,penis enlargement, Menstruation problem and many more. Contact him today and get your problem solved.
