It depends on the bar. If you already are well-established socially somewhere, you usually tend to self-select into establishments that kind of cater to those established friend groups.

For recent transplants they roam bars until they find one with more singles and folks looking for social interaction. They do exist, but are probably more rare.

My theory of course is that the latter type of bar morphs over time (decade+) into the prior type of bar as "friend groups" get established at the new place. The new place slowly turns into the old hangout spot.
When you say "The NHS" people think it's a national thing. The discussion in your article isn't a measure being talked about by the NHS, it's a thing being talked about one clinical commissioning group. There are about 135 CCGs in England. Vale of York CCG covers a population of about 360,000 people. (Out of a total of 60 million in the UK).

> If you cannot afford private insurance, you will only have NHS.

Yes, that's the point. If you can't afford private healthcare in the US you have much more limited options.
>some still use paper and pen and a folder.

Things like this are mindboggling to me. I don't understand how people can claim the USA is the greatest country in the world, it's so backward.
Not even that, data-mining reveals data that wasn't directly gathered.

We need to gather data to operate government (in this case healthcare), so there has to be a more realistic approach than "don't gather any data".
The DS also used the ARM7 as a co-processor in DS mode. And the 3DS has an ARM11 as the main processor with an ARM 9 used for crypto and other low level operating system functionality. When playing DS games they also run on the ARM9. Of course the ability to play DS games implies there's also the ARM7, in fact you can (more or less) natively boot GBA games on it!
I think the titanium powerbook was interesting too.
Note that on ARM it is more annoying to get CPU capabilities as there is no straight cpuid equivalent.

I'm not sure where the development experience with Clojure would have been if it wasn't for nREPL, CIDER, Piggieback and the rest of the team. I've used them all via both vim-fireplace and now Conjure. But I'm sure we wouldn't have been in the same place without them.

This is such an important point !

History has many examples of how fatal and disabling diseases were conquered by medicine, giving billions of people healthy lives. Each of these victories is celebrated as human mastery of science, and dominion over its environment.

Fast forward to now, and there is a small but growing rejection of this idea, and instead the concept of individual liberty has become sacrosanct, to a point where it appears to be valued more than public health.

I dont think this is really the case.

I prefer to think that people have become accustomed to living comfortable long lives in excellent health and that people have forgotten how far we've come, and how we got here.

I haven't done empirical research, but most of the sentiment for freedom of choice seems to come from highly developed areas of the world, where people have lived with the expectation of good health and without fear of epidemics, for 2 or maybe 3 generations.

I have yet to read of any such sentiment in developing nations of Africa, Central America, and eastern Europe where they perhaps remain more aware of the dangers of disease spreading in a community.

They were talking about escaping orbit (reaching escape velocity which is ~41% higher than the orbital velocity and requires getting more fuel into orbit), not degrading the orbit so that the satellite burns up in the atmosphere. As the article discusses, the latter has the flaw of putting alumina particles in the upper atmosphere which remain there for many years.
I don’t agree with that (in fact, that specific case is a crime similar to physical aggression in the country where I live).

In many countries, hemp was banned as part of the ban on cannabis. The US effectively banned hemp production prior to WWII, although temporary exceptions were made during WWII due to needing hemp fibre for war time production. Hemp production was only legalised at a federal level in 2018(!).

Why hemp was banned is an open question. Various theories involving the DuPont family, Andrew Mellon, and Randolph Hearst exist, although evidence supporting them is scant. Alternatively, the whole thing may just have been a mistake; cannabis was often called "Indian hemp" back then, and it does contain trace amounts of THC.

In any case, at least as far as the US goes, hemp was competing quite well with cotton (it was a major crop in Kentucky prior to the civil war); the decline was caused by the legal system, not economics.
So watched the talk just now. I've been using C++ as my main language since the early 90s and it pains me to see what it has become. I thought that I might've been missing something all along. Unfortunately, I wasn't.

The talk all but confirmed my lingering assumption that C++ is intentionally designed to be an over-engineered language with no particular regard to the elegance of its construction. Worse yet, Bjarne did it all of his own free will rather than being forced into that by "the committee" (which would've been a weak, but acceptable excuse).

If C++ were created just today, out of thin air and in its current form, there is no way in hell it would've seen any adoption. C++ is basically a long running bait-n-switch scheme. Come try a better C and then see it evolve into the Homer's car, which you have no choice but to use because it's now - surprise - an industry standard.

So, yeah, there you go /rant.
No, those people endanger themselves by going out in public. Instead they could stay inside as much as possible to reduce risks - even indefinitely self quarantining if needed. Or maybe they should only go outside if they’re wearing a full body PPE that is sealed off and has its own air supply.

My point is, those who can’t get vaccinated have choices to keep themselves safe, and their decision not to take on those inconveniences shouldn’t result in OTHERS being coerced to undergo a medical procedure. I think it is disingenuous to place agency on those taking no action by skipping the vaccine.

I feel like the lack of recognition that "the government" means "the people's expressed will" (albeit there's a gap there in representative democracy) is a major problem in society.

Simultaneously said gap between the government and the people is also a massive problem.

It's a tough nut to crack (ie a hard problem) as those in power are generally loathed to close the gap, as that relinquishes power.

Meanwhile the average person send to be something of a political ignoramus prone to manipulation, whither the power and expression of democracy now?!?

> LTO is cool and all but is the "compressed capacity" number really something to repeat with a straight face?

In JavaScript its good practice to check function parameters for errors. TypeScript (TS) fans call this "poor mans type checker". It has however several benefits over TS. Like more simple then extended type declaration:

Vs

type NonEmptyArray<T> = [T, ...T[]];

Or if you need to check if the array has exactly 3 items. How would you do that in TS?

The author confuses Anger (emotion) with the behavioural response to anger. And from there everything goes down the hill. Here are some facts to navigate easier this subject:

//> Anger is a primary emotion; its opposite is Fear.

//> Ager is triggered by "an obstacle to the satisfaction of needs" - not feeling Anger when you encounter an obstacle is problematic, your chances of survival decrease.

//> we experience Anger in many forms, depending on intensity - from mild annoyance to red hot rage

//> the behavioural response to Anger can be productive or not for us: if you hit back the table corner you just hit, there is nothing productive in that

//> the big problem with Anger is the type of behavioural response we use: intrinsic/instinctual - that is usually violent - or intentional - such as setting limits, being firm, withdrawing, etc.

The whole point of justice in society stems from this intentional management of Anger at scale.

Anyway, it's disappointing to see a psychology subject tackled by a philosopher where from the first sentences is clear that they are not familiar with the subject. But that doesn't stop them from talking about it. But I guess knowing something and thinking that you know something feels the same.

I wonder if the US will ever introduce a department like the FDA except for electronics.
Which plan is chosen has a dramatic impact on performance. Various stats tables give clues which plan will be best, but there will always be queries where the stats still don't lead to the optimal plan...

Therefore, I believe all query engines should allow the changing of a plan mid query. Ie., when a query or subquery is not producing matching rows as rapidly as predicted, the query should be paused, a new plan selected, and the query continued with the new plan.

My testing of this on a fork of postgres found some queries can see a 1000x speedup, especially ones with tens of joins.

This leads to some complexity around cursors, but in my view, this complexity is worth it.

Most of these points are just a matter of personal preference. I like Apple laptops but they're not great in terms of repairability, extensibility, modularity and openness.

There are some non-Apple laptops with much better displays BTW, even Lenovo ships 500 nit displays and wide-color gamut ones with some their laptops nowadays. Dell and other manufacturers ship OLED display with some of their gaming laptops, which far outperform any Apple laptop display.

Regarding Aluminium vs. hardened plastic / titanium I'd say it's just a style question, I have never had any issues with my Thinkpads and they're way more resistant to scratching than Apple laptops (a poor colleage of mine badly scratched his new Macbook with his steel wrist watch only days after receiving it).

Regarding upgradability I prefer being able to extend RAM and hard disk as well as easily replace the battery, again Apple is a poor choice in regard to that.

Regarding repairability Apple actively keeps me from being able to repair my machine, take e.g. a look at Louis Rossmans' Youtube channel to learn about some of the crazy stuff Apple does to keep independent repair shops out of the game. Again nothing that I want to encourage.

That said the introduction of the M1 chips is pretty great, I plan to buy a Macbook Air as my second laptop for office work, I'll keep developing on a Thinkpad with Linux though.

Thorium based nuclear power, instead of trying to minimize consumption of dirty (coal/oil/gas) or expensive-limited-impractical (solar/wind/wave) energy. We should (again) focus more on producing energy that's too cheap to meter. I want my flat-rate power subscription, and I want it yesterday!

We've invented this artificial energy scarcity problem by refusing to use the cleanest and safest solution out there, even traditional 60's era nuclear power kills fewer people per unit of energy produces than any other source of energy.

I put this down to virtue-signalling more than anything else, but even so, nuclear energy is what I'm surprised we're not working on more.
>My understanding is that &mut still needs to be a unique alias even when it comes from an UnsafeCell.

That is correct. steveklabnik was not talking about this.

UnsafeCell needs to prevent optimizations that reorder accesses to the `&mut` derived from its `*mut`. If reordering was allowed it could be possible that you write code that creates two `&mut` (or one `&mut` and one `&`) that appear to have distinct lifetimes (which ought to be well-defined) but are nevertheless reordered by the optimizer to overlap (which is aliasing, and thus UB).

It also needs to disable the assumption that a `&Foo` is immutable if `Foo` is `UnsafeCell` or an aggregate that transitively contains `UnsafeCell`.

This special behavior is why UnsafeCell is a lang item.
> The density of flash memory is competitive with magnetic tapes, but the retention time is too low, making flash memory completely unusable for archival storage, even if it would have been as cheap as magnetic tape.

I disagree that it's unusable. You'd end up with a puck the size of a data tape that can archive a petabyte of data and needs to be plugged in to a 5 watt power supply for long term storage. That's not super onerous. Then consider that tapes need to be stored at exactly room temperature with 20-50 percent humidity, while this puck would barely care about environment at all. And you could plug it directly into a computer without a $5k drive. Honestly it sounds pretty good to me. We just need to drop the price of flash by a factor of 20 to make the scenario happen.

I wish people (even physicists) would stop saying that the heat of reentry is from air friction. It isn't. It's from compression. The air cannot get out of the way fast enough, and it compresses, and compressing a gas raises its temperature.

That's why the leading edge, where the air is moving the slowest, is the hottest.
