I think it's very obvious that vaccines protect against covid. Like that's not even worth a comment. There are many many studies and sources showing this.

An argument worth having could be whether or not that is tied enough to workplace to fall under OSHA.
Health care tied to employment is an invention within our lifetime. Free health care from employers has been a thing for a long time - since the 50s, but the rise in costs to the point where it's untenable to purchase individually is new, driven by laws forcing employers to provide it.

In the 1980s, it was possible for families - Two adults, two kids - To buy health insurance for <$100/mo. https://listwithclever.com/research/healthcare-costs-over-ti... . Prices started spiking in the 90s, but really skyrocketed in the 2010s.
The stats are clear. Back-over accidents are directly correlated with a) large vehicles and b) the high belt-lines and "as close to a truss as we can get away with" body lines that make modern vehicles "safer".

Amtrak milks the North East Corridor to subsidize its woefully expensive and useless service in most of the rest of the country.

There is absolutely no reason anyone should be driving to and from Boston/NYC other than Amtrak being a shit show.

Boston to NYC should be a little more than an hour on real high speed rail. Even assuming you can’t do real high speed rail it should not be more than about 2.5hrs.

And it should be running every hour at most.

Likewise the jabs aimed at the founding fathers by people who have an obvious axe to grind (namely an imperialist one). You'll forgive me if I prefer not to reject constitutionalism because it conflicts with someone's preferred method of exploitation.

qalc[1] is also quite nice if you're looking for a command line calculator; it handles units well, but has some other fancy features, and has a very lax parser which i find to be a huge plus.

In his email, as I understand it he’s addressing people who think like that.
I'm so sick of hearing about COVID-19...

The virus completely endemic at this point, it will never be eradicated. We have a vaccine that is effective and free to all who want it. Breakthrough infections happen, but not often and those who get them usually recover. Will I need to wear a mask for the rest of my life? Will I need to worry about my children staying home from school forever? I want to forget about the virus and get on with my life.
A good example I like to use about how much they are intentionally cultivating these values is to compare the requirements for becoming a citizen vs getting permanent residency:

Citizenship gives you full rights. You can vote, you can’t be deported from the country, you are a Japanese citizen. To qualify for this you need to live and work in the country for five years.

Permanent residency is like citizenship but not as many rights. You don’t necessarily need a job to stay in the country, we promise not to kick you out…unless you do something blatantly anti-social (crime). To qualify for these reduced rights takes…ten years. Twice as long as citizenship would.

But part of the deal with citizenship is you renounce your other nationalities and really commit to becoming Japanese. The government will send a representative to inspect your life; your apartment and social circle, and make sure you are sufficiently integrated. But if you’re willing to commit to Japan, they’re willing to have you after just five years.

But if you’ve been living there for years and still don’t want to commit to the community, they will begrudgingly give you PR, but they’ll make you wait twice as long in protest.

It’s a tough system, but it’s incredibly effective at protecting their cultural values that enables things like Tokyo to exist.

For what it’s worth, while I’ve experienced my fair share of racism there, I’ve also been embraced far more than I’ve been rejected.

I remember eating at the Michelin 3-star sushi restaurant of a famous chef who became infamous for how he was treating/refusing to serve some foreigners. Just getting a reservation as a foreigner was insanity.

But when I showed up (in a new suit, no less) and spoke with him, he kept us by the bar chatting with him all night. He just struggled dealing with non-culturally Japanese people come in, not understand what he was trying to do, and destroying the atmosphere he was dedicating his life to creating.

I knew the rules, and he was an incredibly gracious host to me and my guest as a result.

Japan is far more xenophobic than it is racist, but they’re more so xenophilic once you get a drink into them ;)
> Sounds a lot like Nix's philosophy of totally sandboxed/declarative package builds

They are similar but I think of Nix as being closer to Dockerfiles than to Bazel. Nix describes how to compose and build things, of multiple build systems, in a unixy environment. It sandboxes things and runs commands in those things like `make install` and then pulls the files those commands generates out and uses them for other things. This is very close to how people use Dockerfiles but very different to how someone would go about using Bazel. Bazel's main selling points are that it allows you to describe how your software is built by using application level concepts. Bazel has `library`, `binary`, and `test`. Regardless of what the language we're talking about any two programmers will probably know what these high level concepts mean and, due to conventions in rules, any developer - regardless if they have experience in the language in question - can understand what is going on.

Bazel is also much finer grained than something like Nix. For example, the NixPkg for abseil-py is defined here: https://github.com/NixOS/nixpkgs/blob/nixos-21.05/pkgs/devel...

The BUILD files for abseil-py are found in the repo. Something you'll notice is that there isn't a single build target for all of abseil-py. Instead, each python module or "library" has it's own target: https://github.com/abseil/abseil-py/blob/master/absl/BUILD#L...

This allows for some cool stuff when deploying your software. Suppose you import just the flags module from this repo. That means that your built `py_binary` artifact will only contain just the modules that you're actually importing. You can also see the dependancy graph for all of your source code by talking to Bazel's query API. Find a bug in a library? You can now instantly query every single `binary` that those source files went into without false positives. That's just an example of something you may want to do but really you now have a way to query the dep graph for all languages and tools so the sky is the limit.

> instead of needing a monorepo with every piece of software you can just grab a reproducible build from nixpkgs

You also don't need a monorepo for Bazel to work. You can use `http_archive` or `git_repository` to load specific WORKSPACEs. For example: https://abseil.io/docs/cpp/quickstart#set-up-a-bazel-workspa...

Also bzlmod is being worked on (a package manager that automates this stuff). This also has provisions for running all of the `_test` targets on deps after they're compiled by your toolchain and on your hardware. This validates that all importing and compiling worked as expected (which most build systems can't accommodate).

People frequently mistake "inflation" for "hyperinflation".

Zimbabwe had hyperinflation. Zimbabwe had a $100 trillion dollar bill:

https://www.dallasfed.org/assets/documents/institute/annual/...

If we had 20% inflation per year for the next decade in the US that would be high inflation but wouldn't be hyperinflation. We are nowhere near that.

I wonder if the crypto bubble creates a "wealth effect" that makes people feel richer, spend money, and drive inflation.
> other common ones like the MMR vaccine (components range from 30-90% effectiveness)

That's not what the CDC says. The CDC says [1]:

"One dose of MMR vaccine is 93% effective against measles, 78% effective against mumps, and 97% effective against rubella.

"Two doses of MMR vaccine are 97% effective against measles and 88% effective against mumps."

Very different from either flu vaccines or COVID vaccines. Especially since, when talking about any vaccines except flu and COVID, when the CDC says "effective", they mean "prevents you from getting the disease at all or being able to transmit it to others". The people who could still get the disease or transmit it to others are the few percent for whom the vaccine is not effective.

Whereas, when the CDC talks about COVID vaccines, reducing the severity of illness or reducing (not eliminating) the chance of passing it on to others are what you get if the vaccine is "effective" for you. So not only has the meaning of "vaccine" been changed, the meaning of "effective" has been changed as well.

No, there were no free "servants" in ancient Rome.

Incidentally, even today, "servants" (domestic workers) are often enslaved or work in conditions that are only nominally not slavery. Many are children at an age that is too young to work legally.

>> All of a sudden "An intact servants quarters found in Pompeii's ruins" doesn't sound all that enticing of headline.

The actual headline is not clickbait, if that's what you're suggesting, neither is it spiced up to make it more "enticing", or anything like that. Rather, the headline you propose is an anachronism because there were no free "servants" in ancient Rome. The role of "household servants" (domestic workers) was fulfilled by slaves.
I agree , lived in a few cities, travelled to many, shits on all of them.

I do not want anyone the have the ability to break the cryptographic pairing of my devices without me knowing it.

I do want the ability to swap out parts.

I have no idea how to combine this... it's the same problem as with diffie-hellman key exchange but instead it's in a physical world where you don't have the double asymmetric encryption option since it's not how the physical world works.

Of course a lot of people will be all up in arms about independence and money and power etc. but nobody has had any solution for this yet. I have no idea how to solve those other practical problems without solving this cryptography problem first.

Did MIT actually fire Father Daniel Moloney? Quoting the very top of the linked article about him:

> Two days later, the Archdiocese of Boston forced him to resign because of it.
> By limiting the president's powers to just vetoing legislation

The Irish President cannot veto legislation outright. If they have concerns about the constitutionality of legislation, they can refer it to the Supreme Court for an opinion on its constitutionality; they do not sign the legislation while the Court opinion is pending, but if the Court upholds its constitutionality, they must sign, and then the law enters into force anyway if they refuse.

They also have a never-used power to refer legislation to a national referendum instead of signing it. They cannot exercise this power on their own initiative, only when presented with a petition signed by a significant minority of Parliament. They’ve never been presented with such a petition. If they were, they’d have discretion whether to accept the petition and refer the legislation to a referendum, or ignore it and sign it anyway.

I think, if Australia was to have a directly elected President, we should copy the Irish model and grant the President only this limited veto power. The GG’s current power of veto is rather pointless in that it has never been used and it seems unlikely ever to be used. It is hard to conceive of a scenario in which a GG could use that veto power and survive in their office.

Hacker Superstitions
Asking clarifying questions is a pretty key part of software development. You get a loose requirement the system must do X, you then need to drill into all the details. For this reason I think lots of these coding problems are deliberately under-specified.
I did that for A game in DOS days. It needed a virtual retrace interrupt using a timer interrupt to trigger shortly before retrace, busy waiting until retrace then recalibrating the timer for the next frame.

Pretty soon after that Operating Systems managed memory and interrupts themselves. The added latency on timers made precision tricks like that impractical.
Octothorpe
That might be for historical reasons. (IIRC, mostly, OO was the GUI libraries, and what's layered directly on top of those.) OO is no longer as en vogue, in either Racket or the broader field. In Racket, you'll see a lot of code using `struct`, and without traditional gratuitous use of object classes for everything.

https://docs.racket-lang.org/guide/define-struct.html

> New datatypes are normally created with the struct form, which is the topic of this chapter. The class-based object system, which we defer to Classes and Objects, offers an alternate mechanism for creating new datatypes, but even classes and objects are implemented in terms of structure types.
I wouldn't have supported this a few years ago, but working from home now and surrounded by people operating 2-stroke leaf blowers all day, I'd be pretty happy never to hear one again. It would be better to regulate noise and / or emissions vs the specific technology, but that's probably too much to ask.
>protein assimilability from bread is 40%

This is wrong; the digestibility of gluten is 80-90%. Your friend was probably thinking of the PDCAAS, which is more like 45 for gluten. But this is nutritional quality vs an egg white equivalent as defined by the bioavailability and concentration of essential amino acids (egg = 100 by definition; the score is based on the lowest fraction of any EAA, so gelatin — no tryptophan — has PDCAAS 0), not the fraction absorbed or utilized. For an idea of what utilization looks like see e.g.:

Actually, many mutex implementations first spin in a loop and only then enter wait state. One prominent example is Windows' CRITICAL_SECTION (where the spin count is even configurable). However, I would never call it a spinlock. A mutex might contain a spinlock but not vice versa. After all, the defining property of a spinlock is that it never goes to sleep. One use case outside kernel programming is to protect shared resources in (soft) real time applications where the use of mutexes are forbidden (e.g. real time audio programming). Often you can use atomic variables or lockfree queues instead, but sometimes a spinlock is the only practical solution.
Enforcement might be the reason for that. I never saw anyone get a a jaywalking ticket in the states, but it was an almost weekly occurrence when I lived in Lausanne. Swiss police don’t mess around.

Jay walking also happens a lot in China unless some barrier or traffic warden is involved. This is the case in much of the developing world as well.
Unlike the other examples in this thread, I'll give you credit for that one.

Interestingly the article shows a way for upper-class people to signal upper-class-ness through names. The other kids all have a normal given name, and can easily fly under the radar. But once you start saying all of their first names, it's a clear signal.

(Because it is in line with how many European royals name their children.)

Welcome to Rockfield, from City Skylines
The biggest rule that would make right hand turns safer and quicker for everyone involved is if people respected "Flashing red hand means don't start crossing. If you're not already in the crosswalk, don't start now."

That would give people way more time to clear out the right turn lane each cycle and reduce incidences of people trying to force their way through pedestrians.

But people don't even respect the basic "don't walk" so it's asking a lot...
That's not the point
That seems basically impossible. Salt is really easy to find many places, its taste is _very_ obvious, and it's insanely useful (preserving food).

I'd buy that we don't have great _evidence_ of its harvesting before that, which seems more like what the article says? But that's not really the same thing at all.
For local businesses, I’d agree but the major infrastructure, including trains, are incredibly accessible.

I chatted about it with a coworker who visited in a wheelchair. He couldn’t believe how accessible everything was and said it was the best city he’d ever been to since getting the wheelchair.

Most people have to learn loads of information in a short time and former information doesn't get practiced after. In the span of 5 years, I learned trees at the end of year 1 and a bit at year 2. I didn't need them for anything I did past that. It wasn't until I sat down and practiced a little I was able to think in trees again.

Not everyone covers the same things. Loads of Leetcode tests and interviews apparently cover linked lists and tricks with linked lists. I got zero exercises on linked lists. Some structures require specific approaches, so if you have trouble getting a foot in, you'll fail miserably at any questions related to those structures no matter how simple or difficult.

There are other obvious points, but CS is simply too large a field. What one considers fundamentals is something another never uses, not even in libraries or frameworks. Easier is to prove that the student can learn what is deemed on an equal level as something else, and give them the tools to learn more on their own should they require to do so.

This all assumes the student in question has actually proven to know the material of the course, and the course covers some part of what people consider fundamentals. Things obviously change when considering some people get by despite not having proven they know the material, or CS courses missing these.

I also can't help but feel there is some irony in CS courses trying to accommodate an ever increasing need for more practical skills, ditching CS fundamentals and practicing them to do so, only to be met with interviews which test CS fundamentals despite the work not needing any of it.
