This comment is hilariously on the nose for how a lot of math texts read (at least in my experience)

$SIMPLE_CONCEPT that you’re trying your best to understand is easy if you think of it as a specific example of $MORE_COMPLICATED_CONCEPT that you surely can’t understand without understanding $SIMPLE_CONCEPT
I mean, this all sounds sort of like a reasonable complaint... until you get to the sample size: 3 clicks.

It appears arguably reasonable that geotargeting isn't exact, nor is it clear that these clicks weren't actually real and valuable. If he's trying to make the point that the trend is disturbing, well, then: make that point with something akin to a real sample (at least 1000 clicks, spread over more than a week?)
Isn't the English word Quixotic?
Thanks for the clarification: that, at least, makes more sense than my original reading.

Still seems weird Internet Society would move from maintaining .org to investing for no real gain, but at least it's not "preposterous" as I originally claimed.
> how I always find maths and particularly statistics - I always just want to answer ‘but why’ and then people lose interest in explaining after a while.

Unless you try to solve more problems yourself, you won't understand the advantages or disadvantages of some methods in solving the problems. So the real answer is: construct the examples, compute and compare, don't approach it "philosophically."

All the methods used today survived because they were the solutions to some problems. It doesn't mean that everybody applies them properly: for that you have to get some experience yourself.

Learning about the historical development of the methods is also for me satisfying experience: e.g. logarithms aren't a concept devised for philosophical purposes, Napier developed them to save astronomers time and limit "slippery errors" of (their) calculations:

A clear example of how speech on Facebook has everything to do with power and money and nothing to do with the principled defending of speech because (as Zuck said) “The ability to speak freely has been central in the fight for democracy worldwide".

Facebook might have actually had its hands tied here, but the point is that content on Facebook is subject to the influence of power and money, not the influence of principles.

At least the notice is "X says Y is false" rather than "Y is false".
Is it 'long-form' content or is it a series of points in an overall thread, most of which focus on an image? It could almost be a gallery of images with captions, but I think it would seem very out of place on imgur, for example.

I can’t think of a much better alternative, really. Maybe Medium, but I’d expect something there to be more content than this, with more rewriting and editing. This is more like a 'stream of thoughts'. Is there a specific harm in it being posted on Twitter?
If you are using sonnets to decide that, everybody would be better off if you did study Laplace transformations instead. It is harder to be confused with real life.
It's kind of problematic that they roll back the time on user comments as well. This kind of "rewriting history" can lead to all sorts of issues.

> In fact, I'm sure that you're lying too: every time you Ctrl+Z in between commits, you're removing parts of your audit log. Choosing when to commit is telling a story.

And I disagree here. The way I view it, my editor is my sandbox, I keep playing in it until I have something that I want to enter into record. When I commit work, I enter it into record, with a commit message explaining what the piece of work is.

But to be honest, my repo clone is sort of my own sandbox too, I don't consider Git a fully append-only log, so I'd sometimes do commit editing on my local repo. But once published, I consider it immutable.

(Or rather I'd prefer to; the team in the main project I'm working on right now has a rebase-heavy workflow.)

On a practical note, I'm fine with history cleanup done on the spot. E.g. I've committed three things in the past hour, I squash them together. Or I rearrange stuff I made over the course of the day. But I don't like attempts at messing with history that's many days old (or more), because at that point the person doing the cleanup doesn't have the context of the work in their minds anymore, so history edits throw away valuable information.

Wait till you get into Theoretical Physics, where the same thing is being explained by people who don't even have a firm grasp of $MORE_COMPLICATED_CONCEPT, but know just enough to be dangerous with it.

E.g.: I distinctly remember that many of the original articles about the Amplituhedron spent like a page explaining what a triangle was, then jumped straight into functions over higher-dimensional analogues without explaining any of the intermediate steps. Something-something-logarithm-of-a-simplex.

I can grok what a simplex is, but they literally just hand-waved over the bit where they take a logarithm of it in some way.

The page of explanation of what a triangle is was of zero assistance.

I regret being so cynical about this post and the book I mentioned.

It's a really nice book. Lots of beautiful illustrations and interesting ideas with code snippets for generating those illustrations. I found it fascinating as a kid. The message wasn't too important for me, and I didn't really have the background to draw my own conclusions from it anyway.

Someone on IRC, who was a big fan, introduced it to me.

I actually started programming with this very book, copying the examples from it into Python and then Scheme (introduced to me by that same guy) and Common Lisp. I respect Wolfram's dedication. It's the type of dedication that brings us things like Mathematica and TempleOS.

The guy who introduced me to this book and then Scheme had contacts at Wolfram Research and later sorted me out with a free copy of Mathematica. I could never have afforded that with my pocket money, and I wasn't at university yet. He was a big underdog in the community and had his own problems too. What a great guy.

He's still going strong today: http://xahlee.org/

There's something to be taken even from book like this. It would be good to revisit and re-evaluate the book as someone who now has a semblance of an education in the area. I wish I didn't sell it.

For over a decade, I have run a successful tutoring center focused on math and science for elementary school students in a developing country. Our students won numerous awards both at the national and international levels.

We usually employ teachers with degrees in math or science, or sometimes engineering. Occasionally for early elementary levels (grades 1-3), some teachers have a degree in another discipline. Regardless of major, we always test them for math aptitude. The test includes competitive exam questions focused on mathematical understanding and problem solving skills, rather than advanced math knowledge. (The other part of teacher selection is interviewing for teaching skills and trial teaching with student and expert evaluation.)

Somewhat surprisingly, even some PhD candidates in engineering may fail these tests, while a few liberal arts degree grads passed the lower levels of these tests. So math aptitude is not limited to those who majored in math, science, or engineering. (Note that many of our elementary school students who have studied with us for a couple of years also pass them at a high level.)

It seems that countries with successful math programs, like Singapore, also utilize a rigorous teacher selection process that favors subject matter specialists even for teaching at an elementary level.

This is crucial for math, which is particularly hard to catch up later on with shaky foundation.

(In fact, kids are great at absorbing their teacher’s attitude toward the subject. It is no surprise many kids may sense “math fear” from their teacher. Having a teacher with positive attitude toward the subject they teach is essential!)

> You should easily be able to update tens, if not hundreds of thousands of DOM nodes, assuming you aren't doing anything weird like blocking on layout in one of them

Last I tried that was back in 2013. Haven't tried that particular benchmark since, but have tried others, and I don't believe things have changed much to move that particular needle.

The benchmark was updating the translate3d(random, random, 1px) of multiple 20x20 divs with a black background. It would increase the number of divs until we'd start to have dropped frames.

Obviously no re-layout, no repaint, practically no time spent on the script, and no GC. Compositor only.

Chrome on Windows on a beefed up PC maxed out at around 400 squares (divs).

So no, hundreds of thousands of divs would not be possible. Not on Blink's architecture at least. WebRender is trying to change that, but it's still too early to tell.

I tried the same benchmark with hand-written WebGL, and made sure that the black squares are drawn one-by-one to simulate how Chrome did it (no batched draw calls).

That maxed out at around 1k squares. Obviously all that time was being wasted back-and-forthing between the script and the GPU.

Then tried batching the draw calls (square coords on a large typed array), and that got me to, iirc, millions.

> That someone possibly had the mistaken belief that this was peak performance for a hand-rolled WebGL codebase shows how low and out-of-touch our expectations for performance really are.

True. It is mathematically impossible for react to beat hand-optimized WebGL. I'd guess it won't come close to 1/100 of the raw throughput. It would require a different programming model. And then it would no longer be React.

anything-org.us, anything-org.xyz, anything-org.com, or even just disregard bothering with .org entirely since it literally has no meaning; there's no enforcement on the soft policy that it represent non-profits. For example, slashdot.org is owned by BizX.

Old-guard nerds have nostalgic attachment to the .org TLD's history; that's it. It's hardly a case that it's a monopoly.

I’m building a side project that has an enterprise customer, and the Enterprise Ready website was a good intro to the concepts that enterprises value: https://www.enterpriseready.io

From my (limited) experience, one thing that enterprises love is asking you to fill out a 30 page security questionnaire. They take an age to complete so be aware of this if you’re thinking of going down the enterprise-sales path. I think it’s one of the big reasons that “contact us for pricing” exists for very large customers.

> the theoretical results and incomplete evidence are persuasive enough

In the quoted example, "direct evidence" from that paper was not necessary to confirm that the other calculations and models match. The achievement presented in that paper was to measure the specific neutrino flux, but there were many other measurements before that matched the developed models and weren't less convincing.

It's always good to read more than only journalist's interpretation. Here's from the paper itself:

Eve before "solar neutrinos from secondary processes have been observed, proving the nuclear origin of the Sun’s energy and contributing to the discovery of neutrino oscillations."

Only "those from proton–proton fusion have hitherto eluded direct detection."

https://www.nature.com/articles/nature13702

The paper itself stated that the reactions in the Sun were already proved.

HN is a bubble.

I've been running PPC ads for highly targeted keywords for the last 5 years which have generated a ridiculous return. In general ppc is steady and reliable once you have you're keywords and ads running for a while and are well optimized.

On the other hand, I've recently been trying dropshipping, advertising the product on Facebook.

I did a small test for a unique product, I sourced it from China for around 5 usd and sold them for 25 usd.

People actually bought them on site even though Amazon has them at a much lower price.

Facebook literally knows people who are high spenders / frequent purchasers and will put your ads in front of them. It's actually stupidly powerful.

It excludes websites. And nowadays you dont want to block ads on websites viewed on mobile devices. You want to block Android ad fraud apps. Google blocked the possibility to do it. Essencially making fraud apps creators extremely easy and luxurious.

And as you can expect, Google has 10 times stricter requirements for websites showing their ads, than for Android apps...

Yes. You might find interesting some very rated ideas as this article - Bayesian Brain. In this view, the brain is a complex system that learns to adapt to and predict its environment, similar to other complex systems like even companies.
Try asking the average western student the same question. Most people -be they young or old- aren't able to do that. Nor is that a skill you actually need in real life.

You should also think about if it's more important (to the people you're telling that message) to get a good wage or if they're fine taking a few years to catch up.

"Understanding" concepts is great and all, but unless they're doing that additionally to training the simple application, they'll most likely start having issues once the tests are up.

Having good grades (and being able to prove their ability on the spot) is definitely correlated with good starting wages. Not so much later on, but it's a massive difference at the start.

The Golgi case seems dubious. Golgi was wrong about the nervous system being continuous, but he did masses of other pioneering work in neurobiology and cell biology. He discovered the Golgi apparatus, which continues to baffle undergraduates to this day. He developed the staining technique which Ramón y Cajal eventually used to prove him wrong! I don't think the Nobel was given specifically for the idea that he nervous system is continuous, so it seems justified even today.

> Bits can't rot in HDD or SSD outside of firmware bugs or transmission errors

The entire photography community begs to differ.

Gradual degradation of stored image data across HDDs of all vendors is very well documented, mainly because the bit rot is very easy to spot when working with visual data.

Bit flips are persistent and they occur on the media itself, not in transmission. There are plenty of theories, including one that argues that bits are flipped by stray neutrinos, but nobody knows for sure.

Here's a WebGL+WASM experiment I did a little while ago, all object positions are CPU updated. It goes to a million objects at 60Hz without breaking a sweat on the desktop machine I'm testing here (1 million is where the demo stops adding objects), all very simple and straightforward single-threaded code.

There are some stuttering frames every 300k objects or so, I guess this is when WebGL needs to grow buffers under the hood. Hoping for WebGPU to fix those problems.

https://floooh.github.io/oryol/wasm/Instancing.html

No matter how you look at it, moving a few thousand things around on screen really isn't all that impressive, you just have to know the weaknesses of the platform (WebGL's is a high draw call overhead) and work around them.
