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 wall tapestry of it. :D Seeing all 43 oscillators all at once

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 remain different! The spreadsheet model of programming

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 only extensive naming but documentation &

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 has involved making internal tools for fast-moving,

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 book's about how n

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, funny enough, equivalent to the parallel postulate. Going on a

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 reading :) Thanks for your review by the way, it

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 disputes during tough decisions, such as in the unlik

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. A high-level description helps makes obvious what's hap

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 text used by programmers. I had to download the

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 chapter of the novel is particularly approachable & wort

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 world that turns accidentally alive (think Gaia) via nanotec

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 volatile. And I'm calling it ~n-to-

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 stupidly a halting error in some versions of IE. Anyway, when I ma

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 Photoshop. Have you tried using Pixelmator actions

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 the deepest physical reality in terms of infor

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 America in general it's only 18%). This is a HUGE

Thanks for your interest. I would love to sell this commercially as a side project but the market is entirely on the US while I'm in Mexico. Cross-country shipping and customs is too much of a pain. The story of my life: I should be in the

For one thing, of course I would add a slot and back drawer, like my current desk ;) And I'm much more fond of wood than steel. I'm guessing the sloping common in old standing desks [1] is a good idea. Legroom requirements are very differen

Ah, I see. Thanks for the tip and the pic. It sounds interesting though somewhat against the simplicity of the current desk. As I detail in another comment, it's not solid wood so it would be pretty easy to create the recessed outlet and a

You should still try asking around, it's a very simple design requiring very straightforward workmanship and few, simple materials. Thanks for your kind remarks! :)
