I'm not sure I've ever used anything more complex than Algebra 1 from IIRC freshman year of high school. Ever. Certainly I'm more likely to go beyond that doing house projects, than at work.

I think I've used trig once or twice for house projects, but by "used" I mean "plugged some numbers into the relevant calculator, without needing to actually know the formula", and if that counts I guess I also do advanced cryptography and all kinds of other crazy stuff daily, like when I used GPS or access a web page over SSL.

Far and away the most useful math I was taught in school was the memorization of basic "math facts" (e.g. multiplication tables), including and especially the ability to do mental math with fractions and percentages. This is the stuff (rote memorization) that professional mathematicians seem to hate and want to get rid of or downplay, even calling it "not actually math" et c. Easily the best use of my time in any math class, ever, though I didn't know it at the time.

As far as any utility it had in "shaping my mind", my four semesters of college French were at least as useful for that as my... oh, I dunno, 28 semesters of math? Youtube and reading blogs has been more useful for developing my mind in the way people usually mean when they say that's what learning math's good for, even if you don't use it. I also never use that [edit: the French, I mean] unfortunately, so like math, I've lost almost all of it.

I'd guess 99% of the math I use in a given year could be done by an average 5th grader. Every now and then I take a stab at (re-)learning some math, but it's just so hard to justify the time. What am I going to do with it, really, unless I put in thousands of study-hours to get really good at some niche? Nothing. So I usually end up distracted by some fun-but-not-enlightening recreational math, which is fine, but about as improving as solving Sudoku puzzles.

>"If rich people knew the only way to get good schooling for their kids is to make schooling better entirely, then we'd have better schools."

This is a dramatic oversimplification, to the point of being entirely misleading. Money =/= better schooling. Parental involvement, cultural attitudes about education, and not using a one-size-fits-all approach is what makes schooling improve. Is the implication is that if we forced rich people to send their kids to public schools, they'd use their rich person influence to raise taxes on themselves in order to get more funding?

The problem is we don’t let the market fix it. Instead we continue to pile on regulations that decentivize competition for better health outcomes. Blame the socialist democrats and conservatives that continue to strengthen the monopolies on healthcare because there’s no question about it, too much regulation is the culprit

This is absolutely what happened to the Incan empire predatory to its subjugation to a few hundred conquistadors led by Francisco Pizarro. For those interested check out Last Days of the Incas.
I find it ironic to call something wrong and then proceeding to make speculative statements.
This is the best answer and the article is extremely well written.
Is school about bringing the best up or is it about educating the general populace? Public education in the US is about offering a minimum level of education and acculturation to students. It is _not_ about producing elites.

A contrast to this is Soviet education policy which explicitly tried to select for talent from a young age and funnel them up. In the Soviet Union though, poorer students had full employment guarantees, so the danger of falling through the education system was a lot lower.
My job is split between maintaining a giant legacy perl codebase and doing new dev work in python. I vastly prefer python overall, but perl's still the best when you need quick one-off scripts to tear through log files or do some quick regex subs on a bunch of files.

I don't think python has an equivalent of 'perl -p -i.bak -e 's/foo/bar/g' *', for example (which will do in-place regex substitutions on whichever files are passed in, additionally copying the original files to 'original.ext.bak').

The regex syntax is also bit more streamlined in perl, so I find it quicker and easier to throw together a script that's just doing regex stuff in it. A simple example:

>> $string =~ m/(pattern)/i;

>> my $match_text = $1 || '';

>> $string =~ s/pattern//gi;

>> import re

>> match_obj = re.find(r'(pattern)', string, flags=re.I)

>> match_text = ''

>> if match_obj is not None:

>> match_text = match.group(1)

>> string = re.sub(r'pattern', '', string, flags=re.I)

Of course, the same magic that makes perl great for those one-off kinds of scripts makes it less than ideal for complex or long-living scripts that need to be maintained by multiple people, in my opinion.
For me it was the "fists clenched, looking down, I let out a scream" -- super weird behavior if you ask me.
A lot of people are nitpicking or saying irrelevant shit in response to this, so I wanted to say I think you hit the nail square on the head.

There's a lot of countries with a vaccine uptake in the single digits, and if global health was a real concern we'd be doing something about it, or at least talking about it. Instead, as an example, Ireland's government are implementing a vaccine passport and buying 5x as many booster shots as the entire population... Ireland has a 90% vaccination rate.

Our pundits are talking mad shit about the 10% of unvaccinated people, blaming them for the whole virus, while other countries have a 99+% unvaccinated rate. There's sensible 'putting on your own oxygen mask first', then there's selfishness, and then there's bizarro-world whatever-the-fuck this is; beyond delusion and greed and terror.
It's terrible branding because it makes other parents jealous and then this happens.
I had something similiar -- Got so far ahead of the other students in 5th grade math that I got tossed into a computer lab with a bunch of original IBM PCs and several years backlog of PC Magazine and Byte to read through. I learned so much from those years.
I think the key is density in Europe vs North America. Europe was living in densely packed cities with domesticated animals in close proximity, while North America had smaller communities and less domestication. As a general rule, this makes disease spread and zoonotic viruses much less likely.
> they should be relabeled as the study harders

Not the same thing. Orthogonal, in point of fact. You can have both gifted and non-gifted who work hard or do not work hard.

Some people are just born stronger, or with more energy, or with more social skill. Some people are just quicker about patterns and facts. And some people are unflagging about whatever they put their mind to.
> Cars are a great example, because we absolutely weigh their costs and benefits.

Exactly. You're SO RIGHT about government weighing the costs and benefits.

Which is why the founding fathers made gun rights the second amendment!

Isn't it great!?

The founding fathers weighed their costs vs benefits and found that the benefits outweighed the costs to such a degree that they deserved a entire amendment.

I'm glad we're in agreement about cost vs benefits.

Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety.
> Not open-source yet

Will it eventually be open sourced?
They saved the world already. It's just not evenly distributed yet. It's a bit like me saying, "hey, you know climate change? that's an exceptional circumstance, well why don't you go live a hunter gather existence like our ancestors did to reduce your carbon footprint as much as possible?"
I think you have to think about your own personal experiences in education. It's a shared burden that most people in this country have to go through a terrible K-12 system, and for many, being separated into a group of kids that at least try compared to the bottom of the barrel, and having a curriculum that is at least a minor attempt to be a challenge, makes a huge difference mentally and physically. I think trying to make the public education work for everyone across the board by lowering the bar at the top is the absolute dumbest way possible to try and improve the system and is going to be a complete failure. I may come across as an asshole for this but I don't really care, I think it's far better to reward the top percentage for trying than to throw them in the shitter with the kids that don't care at all and make them suffer 12 years of their youth learning worthless drivel far below their capabilities. That is closer to torture than whatever problem these people are trying to fix.

There are some who think that if the First Nations weren’t “the first”, that diminishes modern day claims and grievances, making it easier for modern day Canada and the USA to ignore legitimate claims, and treat us as they’ve always wanted to treat us. So, this sort of research is important for many.
The only part of that which is dumb is the ill-advised label, which can easily be changed. Everything else makes sense. Borderline intellectually disabled people and Terence Tao-level prodigies should not be in the same class. That is the dumbest fucking idea ever.

On the flip side VR is just 1 UX innovation away from blowing up.

The rate of gains in mobile computing (M1x), mobile vision (pixel 6 pro) and mobile sensors will make the technical and monetary barriers to VR dissapear within the next 5 years.

Most of the time, Europeans fought one tribe at a time, rather than a large alliance of Native Americans.

Then, in many cases, they made natives fight each other, and they recruited "auxiliary indians".

The siege of Tenochtitlan involved 200,000 Tlaxcalans fighting on the European side.

In other cases, such as the Battle of Cajamarca, they used their horse + armor advantage to kidnap the leader and ask everyone else to stand down.

If natives had fought together as an alliance since the beginning, they would have time to adapt and catch up. Like the Mapuche did (they won the Arauco war).
Also, the guns the conquistadors had kinda sucked and at that time not massively better than bow and arrow (they required less strength and skill, but skilled archers were just as good, and the conquistadors could’ve sent them instead). Arguably the steel swords and armor, plus horses, were much more important.

Huh? Did we read the same book? You know, the one where one of the main characters remembers her father being beat to death for refusing to recant his belief in Einstein's theory of relativity during a CCP struggle session?

She made something appealing to hundreds of millions of people, and they willing gave her money for it. The horror.
They are doing stuff like that, but it doesn't make for sexy clickbait, so nobody posts it. For example, last week Microsoft released a patch for an exchange server exploit that NSA discovered and reported.
Conflating two entirely different things to try to muddy the waters, well done.
Got what you mean, I'll work on the letter ring.

What I actually meant by "all users when they look at the same clock at the same time" is all users in different locations would see that time is the same in letters. For example everybody worldwide would see that time now is R:24.

I agree on the last piece as well. I think using it for some time will prove what would be better for the UTC ring, letters or numbers. Each has its own benefits and flaws as you mentioned.

Would you like to give hTime a go and test it for some days? I'd love to hear some more valuable feedback.
Yep, and then these top percentile will leave the country or state and all of the value they create will go to another country or state. We can take, for example, Tesla leaving California for Texas.

Alright, you've convinced me that it would be a real sacrifice, but it's still so obviously worth it. There's very little I wouldn't sacrifice to do what Moderna could do right now. The worst case scenario seems to be that Moderna employees with "helped develop the most effective Covid vaccine on the planet" on their resumes have to get new jobs, and new treatments based on their technology are developed more quickly now that the whole world can experiment with it.

If they can't communicate their process quickly enough because of the tribal knowledge, then no harm done, and at least they tried.

This is just wrong. Tracking is needed to optimize outcomes across all levels of performance. I hate to sound rude but you have no clue what you’re talking about, in all due respect. Public education, if you think it should exist, must track students. There is no alternative and nobody disagrees about that.

> It isn't. It's the same idea expressed with different words.

But one is "backwards" and one is not?

Unambigious is quite a claim.

Is 3.0 and 3 the same symbol on your view? Depending on context they might denote the same idea (the number three). Other times maybe 3 is an integer and 3.0 is a float and their types are important.

Sometimes my computer spits out 10 to mean the sixtenth natural number, sometimes the second natural number, sometimes the tenth natural number. Its all the same physical thing, however what other physical things its equivalent to depends on context.

A true metaverse will be very difficult to create until we have brain-computer interfaces.

All VR devs are entirely focused on the visual/audio output of devices but one very important detail that is missing is the illusory sixth sense, the kinesthetic receptors.

You can solve x-y axis movement with treadmills, but how do you simulate z axis movement without anyone getting sick ?

This is why a lot of people get nauseous on VR roller-coasters. I personally cannot use a VR device for more than 30 minutes without getting ill.

Personally, I think the steps of XR evolution will go like this:

(1) VR restricted to stationary games that don't require a lot of movement. The stage we're at right now.

(2) AR goggles/glasses are most likely to be more desirable than VR within the next 100 years because they're improvements on the existing world rather than replacements. Workplace tools, heart rate metrics, etc. Basically the first working versions of these will be porting the main apps of iWatch to a glasses interface.

(3) Lateral (x-y axis) VR could be improved to provide more immersive entertainment and games. Still nothing groundbreaking, and you're going to be restricted to using a very expensive treadmill.

(4) Once brain/computer interfaces are successfully developed and approved by government regulating bodies for production and release, then people can plug into the "metaverse". I'm guessing this is at least 100 years or more away (that might be optimistic too)

Also an important thing to note is that the infrastructure needed to support a living metaverse is very important. There is a big question mark on what this is going to look like coming out of a megacorp (especially one as greedy as FB). The internet had the luxury of being open/free/ad-free in the beginning, and had a strong developer community. Apple was successfully able to build a dev community for their iPhone but them and Android are really the only good examples I can think of.

People even avoid developing on Microsoft's OS for less restrictive open-source alternatives.
True. I'm actually fine with that. Main thing is we find a good way to get rid of time zone math! :)

It is an absolutely trivial thing. Nobody should be making decisions about whether to use FreeBSD based on such trivialities.

That said, it really was damned annoying. I like to port my software to AIX, FreeBSD, Linux/glibc, Linux/musl, NetBSD, macOS, OpenBSD, and Solaris. All of them use a Bourne-like root shell except FreeBSD, and every time I go to upgrade a FreeBSD VM or build a new one I seem to always trip over that at some point. If I used FreeBSD regularly I wouldn't care as much--I'd change the default, or know how to achieve what I want more directly. But not being familiar with FreeBSD, I always end up in a root shell poking around trying to remember how upgrades work, which tools I need to find documentation for, etc, and end up cursing csh for compounding the mental burden.

From my perspective, changing the default root shell is a benefit, albeit very minor. Though, if FreeBSD (and NetBSD and OpenBSD, for that matter) began publishing official VM images, that'd be worth so much more to me.
