Whoa, that catalog of oscillators is beautiful! Thanks for taking the time to arrange it with your son and for sharing it with us. Can definitely see the appeal of having a giant w…

Thanks for the kind words whacked_new! I agree entirely with your prediction: spreadsheet programming is different from interactive "control flow" programming... and it should rema…

Have you checked the interface that Google Sheets came up for custom functions? It's in the menu of every spreadsheet in Data > Named Functions. It's pretty good and encourages not…

Thanks! It was the first time I gave a public talk to programmer peers so I was quite nervous :)

Hi all, I'm Eli Parra & I gave this talk at ReClojure 2022 in December 3, 2022. Very happy to see this here in HN! A bit of personal background of the talk: my work over the years …

I think you'll enjoy Andreas Wagner's 2014 Arrival of the Fittest https://amzn.com/B00INIQTA6 The title is of course a play on the (in)famous phrase "survival of the fittest". The …

Whoa, that IS neat. Thanks for sharing! A key part of his reformulation is π = α + β + γ (the sum of the internal angles of a triangle equal 2 right angles). That statement is, fun…

Have you read Mortimer J Adler's How to Read a Book? I just finished it a month ago and your mention of terms, propositions and arguments seems straight out of the book's theory of…

How can you get an irrevocable ledger without solving the "no trust" problem?

I didn't understand the very last part: > Another good contingency measure is for only the CEO to hold a board seat before a significant equity fundraise. That will prevent board d…

This is indeed beautiful. But the author limits itself to a low-level unpacking of the regex and running a few tests cases, all the while remaining mystified as to why this works. …

Yes! I guess I'm experiencing an awe at symbolic prowess comparable to that of only-functionally-literate people staring for the first time at the syntax-colored/indented walls of …

> how to deal conceptually with its immensity in time and space Yes! Dimensions (not even the most objective, physical ones) are not absolutes but subject to changing, creative int…

I have to second this. It took me years to thoroughly grasp some of its parts (and I have a math background) but Diaspora is without a doubt my favorite book of fiction. The first …

I second Karl Schroeder as a worthwhile SF author! His novels can be challenging but his ideas are unique and worth the price of admission: * Ventus , his first novel, is about a w…

If you adapted this to Wikipedia articles (a very nontrivial task) you could highlight "authority": how long has a fragment of an article withstood editors.

Thanks for pointing it out, you're right! I rewrote the summary (the original is still at the linked tweet). So it's ~1-to-1 (usually, that's what I mean with practical) when it's …

Hash functions impose practical mappings between unlike domains. When volatile (~1-to-1) identifying (crypto), when correlated (~n-to-n) perceiving (AI). (Tweet summary of the arti…

Yes, I noticed this a lot with Javascript: I would often have a trailing comma at the last element of an array or object. Most browsers would let it go unremarked but it was stupid…

I'm also quite smitten with Pixelmator: it's full-featured, robust, cheap, fast & native! For my purposes, I honestly prefer it to the much clunkier and much more expensive Photosh…

This was surprisingly beautiful. As a geek in programming/computers/information/mathematics, but only a physics admirer from afar, it is very suggestive, even natural, to explain t…

Credit cards & banking are much less distributed outside the developed world. While in the US, 63% of the 15+ population has a credit card, in Mexico it's barely 13% (in Latin Amer…

On a completely different level of mundanity, here are 3 beautiful compliments: Jon Stewart to SpaceX founder Elon Musk: You have invented a rocket, and a spaceship on the rocket, …
