wrycoder··on Denmark will plant 1B trees and convert 10% of farmland into forest
Exactly. It only takes a couple of decades for nature to reforest, which is an eyeblink, actually. And only a couple more decades to return to mature forest. No humans or projects needed. There is a lot more forest in New England (USA) now, than a century ago.
wrycoder··on Voyager 1 Breaks Its Silence with NASA via Radio Transmitter Not Used Since 1981
Fission reactor without a moderator!
wrycoder··on Everything Is Just Functions: 1 week with David Beazley and SICP
If he didn’t cover Chapter five on compiling, he didn’t cover SICP’s best part.
wrycoder··on Everything Is Just Functions: Insights from SICP and David Beazley
Yes. But, I prefer the regularity of the Lisp syntax.
wrycoder··on Mitochondria Are Alive
From an article cited in the OP [0],

More than 95% of all proteins located in the mitochondrial compartments are encoded by the nuclear DNA, synthesized in cytoplasmic ribosomes and imported into mitochondria. These include factors that regulate mitochondrial DNA (mtDNA) gene expression such as mtDNA and RNA polymerases, mitochondrial transcription factors, RNA processing and modifying enzymes, transcription termination factors, mitochondrial ribosomal proteins, aminoacyl-tRNA synthetases, and translation factors (1, 2).

It's clear that a mitrochondrial element can't live for long without the presence of the host cells, so, like a virus, it doesn't meet all the requirements to be considered fully living.

wrycoder··on Ham Radio 101: What is WSPR?
Thanks for taking the time to write this up! My own interests are largely related to understanding EM physics and technology - Ham radio provided the conduit, pun intended.
wrycoder··on I attended Google's creator conversation event, and it turned into a funeral
Same for Amazon reviews.

Here is a much more technical paper analyzing Lippmann's photography:

wrycoder··on An Illustrated Guide to Maritime Signal Flags
This is from 100 Rabbits. Great job!!

One of my favorite flag signals is, “Nothing can be done until high tide.”

wrycoder··on Apple's AirPods Pro hearing health features are as good as they sound
Without the new software, there is no boost to external sound in transparency mode, so they are not useful as hearing aids. I’m looking forward to testing the new release.
wrycoder··on Routine dental X-rays are not backed by evidence
In my experience (average teeth), dental insurance doesn't pay out enough to cover the premiums, and it's not worth the bother.
wrycoder··on The mystery of why left-handers are so much rarer (2016)
Nice, except the liver is on the right hand side.
wrycoder··on Black Hole Destroys Star, Goes After Another, NASA Missions Find
A massive black hole has torn apart one star and is now using that stellar wreckage to pummel another star or smaller black hole that used to be in the clear.

Maximum hype, complete with artist's concepts. It's hard to believe that this is the website of an astrophysics project, but it is.

wrycoder··on Math from Three to Seven
Thanks, your comment makes me want to read the book!
wrycoder··on Essential node in global semiconductor supply chain hit by Hurricane Helene
According to Ed Conway, author of Material World: The Six Raw Materials That Shape Modern Civilization. Russia and Brazil also supply high-quality quartz, he says, but “Spruce Pine has far and away the [largest amount] and highest quality.”
wrycoder··on I Am Tired of AI
Just wait until they get saturated with subtle (and not so subtle) advertising. Then, you'll really hate them.
wrycoder··on Hy 1.0 – Lisp dialect for Python
Sure - you are piling another transpilation layer on top of already slow Python.

Why not just use something closer to the metal: Common Lisp, Scheme, Clojure, Racket? Especially, use a compiled language, instead of an interpreter.

wrycoder··on Nothing: Simply Do Nothing
No argument - simple doesn’t mean easy. When the food runs out, only the the most fit (or ruthless) survive.
wrycoder··on Ask HN: What runs L4-related microkernels/hypervisors these days?
You could check out Helios, which is inspired by L4 [0]

wrycoder··on Nothing: Simply Do Nothing
Well, you put on your furs and go hunting. Tracking is easier in the snow. Or you stay in your shelter and eat some jerky. And, I'm not being glib - life was simple and you did what I said.
wrycoder··on The Waterfall Model was a straw man argument from the beginning (2015)
Here's the Royce paper. Check out page three.

wrycoder··on The Waterfall Model was a straw man argument from the beginning (2015)
With Spiral, the iterations explicitly involve the customer. This is important.

With Waterfall, there is an upfront spec, but implementing the whole thing without consultation with the customer can be a bad experience.

With Agile, maybe there's a lot of internal correction. But the key thing is to involve the customer in integration testing. Unless both sides are very experienced, surprises due to miscommunication are the rule.

wrycoder··on Nothing: Simply Do Nothing
Do what humans usually did - hunt some dinner, hang around, maybe go aggravate the neighboring tribe a bit, if you’re feeling feisty.
wrycoder··on Plain Text Accounting (PTA)
This is the big advantage of hledger. It has two ways of translating csv into journal form - one simple and one more complicated, but very flexible.

I find it best to have a separate journal for each downloaded account. I just include them into a master journal (along with a manual entry journal) and generate reports from that.

I also use git so I can roll back the latest import, if something goes wrong - but that hasn’t happened yet.

wrycoder··on OpenSCAD: The Programmer's Solid 3D CAD Modeller
At this point, there are 138 comments, which, as is often the case on HN, are much more informative than the link itself and show that the topic is hardly worn out. If it was, it wouldn’t have made the front page.
wrycoder··on The magic of DC-DC voltage conversion (2023)
Current is analogous to momentum, because electron drift has net momentum.
wrycoder··on iPhone 16 Pro and iPhone 16 Pro Max
I’m still on the X after a $90 battery swap by an Apple shop. I got tired of the small payback doing them myself - and even the iFixit batteries don’t last as long as OEM.
wrycoder··on iPhone 16 Pro and iPhone 16 Pro Max
I use a slim Spigen case, because I find the naked iPhone is too slippery to handle safely. And I don’t have to worry about laying the phone down on its face.
wrycoder··on Japan’s Temple-Builder Kongō Gumi, Has Survived Nearly 1,500 Years
In this case, the company was providing a service that was needed for millennia - building temples.

Their structure seems to have been like a private corporation, with special rules and efforts to maintain their ideology and culture. They had the ability to expand outside the current leading families when necessary, though.

When they hit the recent hard patch, they pivoted, but didn’t scale back enough to survive until the next great leader showed up. They fell into the hands of modern corporations, and we all know how that turns out.

wrycoder··on Sleep on it: How the brain processes many experiences, even when 'offline'
Since this is processing of past events and future possibles during sleep, would it be fair to hypothesize that animals that sleep actively (appear to dream) are conscious when awake?
