CORDIC is not based on radians or turns; it is based on decomposing the angle into a sum of:

phi_n = atan(2^-n)

and then using an abbreviated sum formula where computing cos(theta + phi_n) depends only on sums and bitshifts.

The small-angle approximations sin(x) ≈ x and cos(x) ≈ 1-x^2/2 are the real killer feature of radians, though, because when you can deal with the loss of accuracy you get to avoid using any loops whatsoever. They're also fundamental to understanding simple physical systems like a pendulum.
Class issues and racial issues intersect. If you skew too far toward class issues, you wind up in class reductionism (the demonstrably false notion that creating economic equality will solve racism). If you skew too far toward race issues, you get... I'm not sure what the term for it is, but it's essentially trying to achieve racial equality by building up a class of Black entrepreneurs and ignoring everyone else.

An interesting thing I've found (anecdotally) is that corporate and nonprofit efforts for "racial justice" skew very heavily toward the latter, but community aid and grassroots racial justice groups strike much more of a balance.
> We did not manage to solve even one none technical problem since we came down the trees. But that's nothing unexpected actually given we're a horde of apes. I'm old enough to know that nothing will ever change as we had already more than enough time to easily mange at least some "humanity scale" issues by now. But we as a species are seemingly bound to our ape nature.

Counter-example: The use of slavery as an energy source replaced by the use of electricity as an energy source.

When you want to listen to music, you open up Youtube (or Spotify, or your carefully curated collection of FLAC files, or whatever) and press play.

When Romans wanted to listen to music, they would tell the slaves to pick up the instrument and start playing.

That's a significant change, IMO.

M-x shell and simple variations (https://github.com/pjj/Emacs-nsh) allow for infinite scrollback, separate histories, comint-based or plain emacs navigation, and ease the manipulation of arbitrary output. Occasionally I close a shell buffer if the output has exceeded a GB or so, but they typically last weeks or months and I never lost info. They are not full terminals, so not everything works and I bind a lot of terminal-only commands (htop, nvtop) to execute in vterm.

Came to use trig functions quite frequently while playing video games, and that was a big surprise to me. Not to assume you've played it, but I've recently discovered that Stormworks is a programmer's game - you can write microcontroller code in LUA for your vehicle designs. And, wow, does it ever use my trig knowledge everywhere.

Realized the transponder beeps can be triangulated, tick being 1/60th of a sec and that's a distance estimate resolution of up to 5-10 km. And that's when cos and sin came back to be useful because you can do intersection of circles and figure out where to do a sea rescue more precisely. So video games, trig. Who would've thought?

I'm not sure what he means by the naive scientific method. It has always been a fundamentally adversarial process, nothing new is being discovered here.

The scientific method as it has always existed requires two heuristics from you, the scientist: a hypothesis generator, a test generator (and an all important simplicity measure). The point of the method is that by making these things work adversarially, we can turn our very messy, fallible creativity, ie these heuristics, into facts about what the model isn't. Moreover no additional hypothesis of what the model is, or test which contradicts it, can derive a false fact of this form, relegating the entire concept of adversary to the meta who-gets-their-name-on-the-paper game.

If Daniel has only
recently started "using science adversarially", then he has only recently started doing science.
I suspect there are hundreds to thousands of such workarounds in a lot of hardware, driver and software considering the billions of lines of code they could be in, much of which is proprietry. I have done quite a few workarounds that fixed odd problems but ultimately lead to worse performance once its fixed. I did my best at the time to try and limit when they applied but there is no easy way to detect the platform in a lot of cases to limit the application or to see into the future, especially when its working around a bug in the operating system and no fix has been released in any reasonable period of time. You can document them as well as you like we don't have a standard for how to deal with these types of things when it impacts common code. So I suspect there are lots of legacy workarounds causing performance degradation all over the place.

> My theory is that physics is stuck in a local minima where it's not sufficient to change just one, or even two or three fundamental things to get unstuck. That's too big a leap via traditional incremental publishing of new theories. Any one change to the status quo won't work, and is rejected.

>the Monarchy serve no real purpose in modern societies

There may be a bit of a Chesterton's fence thing going on. You say these idiots have no function but one underrated function is preventing other idiots taking the ruler for life role. See eg:

Germany - got rid of the monarchy in 1918, got Hitler as ruler for life

Russia - got rid of theirs early C20th, got Stalin, Putin

France - got Napoleon. etc

on the other hand

Thailand - kept the monarchy - only Asian country that was never colonized/occupied by the West partly because the people would object to the kind being dissed.

As another comment said, you’re referring to Verizon’s CDMA network. Which did not use GSM and this did not use SIM cards. Literally, no SIM cards. It wasn’t until their LTE network they supported SIM cards in any meaningful way. Their handsets were locked to their network and only worked on their network. Occasionally, an “international” phone would be sold that had CDMA + GSM so their customers could use it overseas but the SIM card slot did literally nothing here in the states since those phones wouldn’t have supported T-Mobile or AT&T’s network frequencies.

And just because nothing prevents a phone company from offering them, doesn’t mean they will. Having the ability to just move a SIM card is very pro-consumer in a way I don’t think esims will ever be (unless the EU regulates it).

You can slightly tilt the yoke to make the horizontal lines more horizontal (although then vertical lines will be less vertical, tradeoffs everywhere)
> people can choose to use a framework that handles auth competently, such Django or Rails, no need to roll their own

The problem is there's a trend to prefer hyped-up languages with little/no battle-tested frameworks like those so this is literally not an option for a lot of companies where their "backend" is a pile of hand-rolled shit on top of Express.js, FastAPI or other minimalistic framework.

It might be a technically possible option to switch over to one of those, but too many people would have to lose face (at multiple levels, from individual developers all the way to investors) so it will never happen.

> Engage with why you feel so strongly that anything other than rigid adherence to tradition is sacrilege

Who’s saying that? Inventing good notation is a big part of mathematics (and that also frequently gets criticized on HN because it may introduce ambiguities)

Also, there’s nothing wrong with texts that target an audience with a certain level of understanding.

It’s not as if adding, for example, “By Hermetian matrix we mean a complex square matrix that is equal to its own conjugate transpose” will make a paper much easier to understand, just as adding a comment “this is where the program starts running” doesn’t help much in understanding your average C program, or adding a definition of “monarchy” to a history paper.

In the end, any scientific paper has to be read critically, and that means making a serious effort in understanding it. A history paper, for example, may claim that Foo wrote “bar” but implied “baz”. A critical reader will have read thousands of pages, and (especially if they disagree with the claim) then think about that for a while, and may even walk to their bookshelf or the library to consult other sources before continuing reading.

remembering vs understanding is uncompressed vs compressed storage:

If I tell you a sequence of numbers:
1,2,4,8,16,32,64,128

And you try to remember them, having never seen these numbers before, you have to remember each individually and it will not be so easy.

But if you, before trying to remember them, apply a little computing power to figure out that its a sequence of powers of two, starting from 2^0 going up to 2^7, then you have compressed the information I gave you. You understood (presumely) the source of the information and you will be able to remember the numbers much easier.

One strategy I see people applying to unknown data they want to remember is to try to establish links to already known information or made up stories. For example when given the sequence of numbers above but not knowing about exponentials some people would try the follwing:

* 1: the first number is one (as on the number line)
* 2: the second number is two (same)
* 4: I have four friends
* 8: I ate lunch with my friends
* 16: my sister was also there, she is 16 years old
* 32: the house number of the restaurant was 32
* 64: we ate sushi, my dad also likes sushi, he is 64 years old
* 128: one-two-eight sounds a bit like "want to eat" and yeah I also like to eat

By doing so some people seem to achieve quit good memory of an unknown topic. But from my point of view they are only re-encoding the information to sort it into already existing bins in their memory instead of compressing it. The amount of information is not reduced but increased and it seems harder to reconstruct the original encoding/information. Additional without compressing the numbers to their generating algorithm it is not possible to use the "learned" knowledge for anything but reciting.

This all leads to Solomonoff's theory of inductive inference.
Like most here, I've learned and forgotton lots of trig and calculus.

However, I still remember that "eureka!" moment of realizing that radians were special, that the small angle approximation of sin(x) = x, and many related math rules, work only when x is expressed in radians. I guess that's a credit to my math teacher, who basically led the class in deriving mathematical formulas rather than just presenting them to us.

I think the article is still valid and interesting, as "turns" in some use cases might improve performance and accuracy. But radians aren't at all "arbitrary" - if we ever encounter technologically advanced aliens, they certainly won't use degrees, but they will understand radians.

For me act works fairly well, though it isn't exactly the same as Github. Matrix builds didn't work properly (just noticed it has been fixed now), and the base images aren't quite the same.

Github should send a bunch of money to the act developer - I know I wouldn't have used Github actions at all without act existing, I'm sure other people must be in the same situation. (Though I'm not paying Github either, so perhaps I'm not a target customer...)

The concept of Internet Time is genius. Swatch even wanted to send a satellite to space and with that be able to synchronize the time on all the watches.

As others have said, I also think the issue was basing the time on Biel (GMT+1). If it had been done on another timezone, it would have worked better.

Mr. Hayek (the Swatch founder) was a genius ahead of his time.
> I'm currently traveling a lot and in daily life I see a huge difference to how people treat you when attractive. In The Netherlands I'm at best average in attractiveness (I've asked for brutal feedback from multiple people, and I'm averaging 6 out of 10). However, in other countries I'm seen as slightly more attractive because I'm about 190 cm, which is 6.23 feet/inches (whatever you Americans use).

Thank you for an interesting self-assessment. While you're closer to the the average reported height there, I would think that height, as a desirable trait tops out at around 6'7" (~200cm) as back problems or bumping into doorframes becomes more likely.

And given what you've said about yourself, what height, build, and features are considered attractive in the Netherlands? Any notable differences between the men and women there in traits they find desirable whether stated or actual? What about along the along the lines of age groups and marital status (i.e. single, in a relationship, married, divorced)?

Who would be a common example of the "societally attractive" 10/10 in the Netherlands?

What emotional traits are considered desirable(e.g. stoic, relaxed, agressive, etc.)?

How "loose" are the people in Amsterdam? Popular culture stateside exaggerates it out to be a libertine utopia with an unlimited supply of sex drugs, but from what I've read through first- and second-hand accounts, many of them tend to be "shy" (at least relative to Americans) or "friendly, but reserved".

Reminds me of this article I just read: http://paulgraham.com/lesson.html
In commercial world there are whole teams of people to filter reports as not to distract devs from their jobs. In the open source world, bad bug reports really are a drain with negative value. Someone has to read them at the end of the day. Nobody expects the amount to be 0%, but at the same time nobody has time for 200 mysterious reports of "i did something unspecified, and it did something i didnt expect, but im not going to tell you what it did, what i thought it should do, or what version im running"
It wasn't an anti-pattern years ago, but I have a similar gut feeling today. There's a tendency in this industry for yesterday's best practices to become today or tomorrow's anti-patterns as the market evolves to exploit whatever people think are best practices to turn them upside down and shake.
Thanks, that is one way to do it. But if you don’t know about par2 (sorry, I can’t tell from what you’ve said) it’s worth chasing down. It is way, way beyond checksums in what it can do.

It’s an old project and information on the internet is getting thin but the math is sound, the tool works, and there is a wikipedia page:

https://en.m.wikipedia.org/wiki/Parchive

Edit: btw use of par2 files can be added on as an extra step with minimal storage overhead, without replacing anything you have now.
To clarify my objection is with this statement

> no one ever writes down numbers in the unit of radians, they already convert to half rotations or full rotations by scaling with pi

That statement is true only if you are talking about geometry, If you are working in any other domain the trigonometric functions operate on real numbers and have nothing to with rotations or angles and if I call sin(1) I expect to get back 0.7847 not 0

Well the question I responded to was "What does oauth have to tho with authentication".

I fully agree with the move away from plain passwords in this case, given that it's no longer "just" the password to a mail account, but to much, much more.

Now while I think OAuth adds some features that can be useful in certain settings, I'll be inclined to agree that requiring OAuth isn't the best move.

However the alternatives would probably require a lot of extra work on Microsoft's behalf, like being able to set up device-specific passwords or similar.

So, given the need to move away from plain account passwords, I can understand why they wouldn't want to do that and just use what they already had.
I don't think it's so simple, HFCS has industrial advantages over sucrose in addition to the subsidies. So if HFCS were made more expensive it's unclear to me if sucrose would even be an acceptable substitute for all the ways HFCS is (ab)used due to its sweetness, stability, and ease of use advantages over sucrose.

They put HFCS in practically everything processed on store shelves because it's so cheap and checks many boxes from preservative to browning agent, and I'm sure myriad other effects I know nothing about.

That's sometimes true but I think my point still stands.

When I'm studying a foreign language, I learn some words and they stick, but I'm exposed to a bunch more that I don't remember next time. I forget those meanings, but the ones that stuck are now vivid and with me, brighter.

When I'm studying Kubernetes, I end up reading a ton of information that's irrelevant to the task at hand, and lots of it doesn't make that much sense because I'm new to it. The next day, when I come back, the things that I actually understood remain, ready to be the foundation for new learning, which they couldn't have been when they were mere data points in an overwhelmed brain. I don't remember the parts I was confused about yesterday, just this stuff that now makes sense.
