«Today, in the US alone there are 5,000 amateurs who knap fresh arrowhead points by hand. They meet on weekends, exchange tips in flint-knapping clubs, and sell their points to souvenir brokers. John Whittaker, a professional archeologist and flint-knapper himself, has studied these amateurs and estimated that they produce over one million brand new spear and arrow points per year. These new points are indistinguishable, even to experts like Whittaker, from authentic ancient ones.» #link https://kk.org/thetechnium/immortal-techno/

«I worked on a unique HFT system which was capable of starting the response packet before the incoming packet's final byte had arrived. Negative latency. If it mispredicted the future, it would simply scramble the trailer and cause the packet to fail UDP checksum.

It didn't make money in the real world because the quality of decision that could be made at that speed wasn't good enough.»

It's sort of fun when a major media outlet states the obvious which used to be tacit so far: «[American] Atheists Are Sometimes More Religious Than Christians» #link: https://getpocket.com/explore/item/atheists-are-sometimes-more-religious-than-christians (The Atlantic, Pocket avoids the paywall.)

«As it turns out, “American ‘nones’ are as religious as—or even more religious than—Christians in several European countries, including France, Germany, and the U.K.»

I long assumed that the social justice holy wars on Twitter and other social media, mostly waged by American users, are religious in nature. Similarly, pop / rock concert ecstasy and sports fans ecstasy seem similar to religious ecstasy (no, not the chemical one). There's a ton of socially accepted and widespread behavior which one normally would associate with organized religion, happening without any reference to the supernatural. «It’s #religion, minus all the God stuff.»

«Something like Schrondinger's equation is a PDE where the number of dimensions is the number of observables so it can get very high dimensional very fast. Classical methods don't necessarily scale that well in high dimensions (curse of dimensionality: cost is exponential in dimensions), but using neural networks does very well. This gives rise to the physics-informed neural network and deep backwards stochastic differential equation approaches» https://news.ycombinator.com/item?id=23907612 #link #rapprochement

@mujawwad, I remember you didn't like the PDE legwork of science.

 ‎· 9000
Comment

^ PDE legwork of physics, maybe; but actually, once you go into purely geometric things which deal with PDE systems and differ from them because they carry some exotic structures like the boundary conditions that do not matter (in the sense that there are infinitely many solutions to them), you can find an extremely surprising way of applicable reasoning - the possibilities of purely algebraic solutions and the "incorporations" of them into another, more pure, "genuine" solutions - that's what h-principle is about, the deformations of possible solutions. So I kinda want to say that it's not the limitations of classic methods that is disturbing (I admit that I may not be a fan of them from the personal point of view), but it doesn't mean you can't dig into and find something cool or whatever (like with homotopy principle)

 ‎· mujawwad 1
Comment

and perhaps I have to reiterate again that everything that sounds like "well PDE is boring as hell and should not exist" is more of a half-meme in mathematical community; there is no doubt some part of the camp mindset but neither I nor anyone I know (except for some extreme cases) actually thinks this way, because if taken seriously, the interconnections of mathematical knowledge are hardly explored (in the sense "it's hard, much harder than mathematics itself sometimes"). there are levels to metaknowledge somehow resembling n-level voters frameview from voting theory, but one also could think about it pairwise: there are (meta)levels of mathematical knowledge, and each level of its complexity carries its own levels hierarchy of "inner" complexity

 ‎· mujawwad 2
Comment

@mujawwad: PDEs should exist, they are an important tool! But anything that makes solving them easier, numerically or analytically, is useful, I hope. This is one such thing. (And I like the idea " harder than mathematics itself" and the levels.)

«Scrum is all process, but few of them. XP has fewer processes than Scrum, but way more practices. Practices, by the way, that I've heard asserted more than once are the difference between a successful or a failed Scrum team - that successful Scrum teams are using half of XP. In other words, Scrum is simply underreporting the number and variety of success factors, making it look much simpler than it really is.» #programming #quote #link https://news.ycombinator.com/item?id=23909934

«Hydrogen leaks in an oxygen atmosphere (like the one here on earth) are pretty dangerous, as they are effectively invisible in daylight, due to almost all the energy going directly to infrared. Due to that NASA test engineers used to walk with a broom in front of them in areas where hydrogen leaks could happen. If the broom suddenly caught fire, there was a burning hydrogen leak in front of the engineer!

Чтобы он был заметен, задуманное должно быть колоссальным.» (2) «Discounts found to follow hyperbolic geometry and thus to add up as velocities in special relativity.
