cleansingfire··on Cambrian Explosion: When Complexity Met Complexity
Proposes a structural account of the cambrian explosion. The precambrian was the first life, with evolution dominated by geology alone. The cambrian explosion occurred when life finally became the dominant complexity encountered by other life, causing a feedback loop. https://doi.org/10.5281/zenodo.20682905
cleansingfire··on Acetaminophen vs. ibuprofen
Yup. Try to treat the source of the pain. Of course. But dont act morally superior because you don't need acetaminophen.
cleansingfire··on What nicotine does to your brain
Except that ADHD is older than screens, and exists without drugs or addiction.
cleansingfire··on What Did Medieval Peasants Know? (2022)
The medieval period was called the dark ages largely because of our ignorance of it. The Medieval spans about 1,000 years. There were plagues which made labor immensely more valuable, & wars that lasted generations. Any blanket statement about it is bound to be somewhere between false and meaningless. Including this one.
cleansingfire··on Bull markets make you feel smarter than you are
Day Traders only exist because of this. Bull markets allow them to exist.
cleansingfire··on A Scientific American bolt puzzle
When you twiddle your thumbs, your thumbnails always point the same direction relative to each other. So the bolts relative rotation will maintain that. Imagine a stripe on the face towards us of the bolts, and twiddling action will not rotate the stripe in an absolute or relative sense.

For the two bolts, this is equivalent to rotating both bolts so the stripe stays in the same relative position, as if one were rotated around the other or they were twisted in the same absolute direction. If you are concerned about symmetry violation because of the direction of the threads, you can reverse the threads on both bolts, with the same result. You can try this with a couple of bolts and a couple of rubber bands to keep them in the same relative position. The illustration is a hint that the motion is equivalent to rotating both in the same absolute direction (near side moving up.) Then view that system from the head and note the direction each would be moving, away or towards you.

If you have to undo a bolt or nut from behind, the bolt head moves in a reverse direction from your viewpoint, just as if you were to view a glass clock from behind.

cleansingfire··on Zinc prevents vaginal candidiasis by inhibiting expression of fungal protein
I'm concerned about the same mechanism that causes permanent loss of taste with zinc lozenges, and if it applies here. I don't want to poison the nerves in my genitals. It isn't a common or widespread effect, but it is severe.
cleansingfire··on A Matter of Millimeters: The story of Qantas flight 32
Also demonstrated by the picture in the op of the brick wall. Note that it wasn't smashed or knocked down, but looks as if it was cut.
cleansingfire··on Shane MacGowan has died
He claimed alcohol was a mystic sacrament, in an interview I read long ago. That's an awfully destructive spirituality, but it was very much his choice, whether rationalized addiction or not. Personally, I've seen that destruction too closely to find it anything but tragic, but I'm grateful for his poetry.
cleansingfire··on Why I always hit the crosswalk button (2015)
The button has no downside, with a possible benefit, so always push it. Also refers to discredited Bystander effect nonsense regarding Kitty Genocese murder: "there is no evidence for the presence of 38 witnesses, or that witnesses observed the murder, or that witnesses remained inactive." https://psycnet.apa.org/doiLanding?doi=10.1037%2F0003-066X.6...
cleansingfire··on macOS Sonoma Boot Failures
Only affects Apple silicon chips (intel unaffected) with ProMotion display. Just a quick Exit clause for people with older machines.
cleansingfire··on Toyota’s advanced battery technology roadmap
If they understood significant figures, it would be less suspicious. Besides, when a vendor uses their own special metric, instead of a well known standard, I lose respect for them.
cleansingfire··on Shannon's Mind-Reading Machine

cleansingfire··on Landauer's Principle
Reversible computing cannot lose information or energy. No dissipation allowed.
cleansingfire··on The core problem with hamburger menus
Assuming the bottom is even accesible! I believe it's somewhere in the Amazon ios app where I see a promise of a useful footer that is always pushed off the page by infinitely scrolling things they're pushing at me instead.
cleansingfire··on The Best Pens for 2023: Gel, Ballpoint, Rollerball, and Fountain Pens
Amazon doesn't even organize or allow you to search for SHOES by size. Their search is about forcing crap down your throat and is actively hostile to getting what you want. I wish the reviews were the worst of it.
cleansingfire··on Xylazine, a dangerous new drug fuelling Canada’s opioid crisis
I thought of Krokodil also. Considering that tiny amounts of impurities can cause terrible consequences. MPTP impurities in MPPP caused parkinson's, and bad commercial synthesis of tryptophan by Showa Denko caused EMS, it seems likely that this is real.

cleansingfire··on Clocks and Causality – Ordering Events in Distributed Systems (2022)
Original Lamport paper here https://lamport.azurewebsites.net/pubs/time-clocks.pdf
cleansingfire··on The Anti-Productivity Manifesto
I think this is why the Dunning-Kruger effect exists, and why casinos make money. Unreasonable hope is necessary if you are going to do anything interesting. Failure often teaches more than success. Knowing we will die is intimidating. https://www.google.com/search?q=wood+allen+the+universe+is+e...
cleansingfire··on Show HN: GPT-4 Reverse Turing Test
It is brilliant satire, written as if by a machine claiming to own empathy, while demonstrating none.
cleansingfire··on What happened with the substation attack in North Carolina?
Statistically they were americans. Foreign terrorists are historically negligible compared to domestic.
cleansingfire··on The Globus INK: a mechanical navigation computer for Soviet spaceflight
Wow! An analog dead reckoning computer with a beautiful display. I'm especially intrigued by the cam based CVT (constantly variable transmission.) I'm glad to know this exists. Thank you for sharing the details.
cleansingfire··on Ask HN: What do you think about stickers on laptops?
After reading this https://www.reddit.com/r/tifu/comments/5e4j2i/tifu_when_i_ac... I put a sticker over the logo. Helps me not grab wrong laptop at work too.
cleansingfire··on Meta CTO told employees higher headcount resulted in 'untenable' slow movement
Paraphrasing the title: Management Blames Employees
cleansingfire··on Visually symmetric words
I had to work harder than expected to get this. I interpret the cartoon as distinguishing between meaning and form. Until I read it aloud, I couldn't stop interpreting the strings as

open close open close

in both directions.

cleansingfire··on The leap second’s time is up: world votes to stop pausing clocks
We have a GPS time server (so stratum one) that is set to GPS time, so it's off from UTC by almost twenty seconds because they don't ever apply leap seconds. I love it. Another part of the org pressed me to correct my time to match UTC, but I'm so happy to be done dealing with time changes that I just replied "monotonic time" until they got their own. A few grand to not have those problems is such a bargain!
cleansingfire··on The rabbit hole of adding grain to digital photos
You prompted an idea I find fun: If film grains are randomly or chaotically distributed, and fractal over enough orders of magnitude, grain might not be error but a medium which interprets and conveys information differently, with unique advantages.

But now I'm afraid I sound like an audiophile who buys wooden amp knobs for performance.

cleansingfire··on The rabbit hole of adding grain to digital photos
Noise can improve recognition of marginal signals,so this might not just be aesthetic.

I first learned about this in vision, but it's generally true. https://www.electronicsweekly.com/news/research-news/add-noi...

cleansingfire··on Split Your Overwhelmed Teams: Two teams of five is not same as one team of ten
It's so refreshing to be reminded that much of what we're looking at may just be the equivalent of useless self help books. Nobody goes broke oversimplifying problems and selling cheap fixes, and as technologists who have seen the power of technologies to exceed the power of magic, we're vulnerable to believing too much. Churn is not progress, and easy is rarely right.

Thanks for the reality check.

cleansingfire··on Round-Up AA and AAA Cells (2022): Results and Analysis
I'd like to see these now rated for leakage by monitoring, maybe even shorting half the sample. As far as I can tell, all cells now leak, while before it was some cells and aggravated with constant discharge.

Edit: Because I would like to know if I can trust any (other than rechargeable or perhaps Li) cells not to destroy my toys.
