Gravityloss··on Martian chaos terrain
99% of scifi papers over these things. Somehow people always land in nice flat areas. Aliens' ground vehicle was modified from an airport tow truck. Talking about convenient flat land.

Even on Earth, with weather and generous erosion, large portions of land are very dense forests or very rough mountains.

Gravityloss··on Replacement of petroleum based products with plant-based materials (2025)
You're right, I was kind of inspired by the comments and my comment doesn't fit completely.

It's just interesting to think how we end up in these situations and then society is what it is and individuals have limited power to change it on their own. (That said of course individuals also do have power and sometimes blaming society is just an excuse).

Gravityloss··on Replacement of petroleum based products with plant-based materials (2025)
It's generally easier to envision a small amount of changes at once. But for something like walkable or bike or public centric transportation, multiple things need to change before it makes sense.

Ie with a car, you go to grocery store once a week. You buy lots of things.

If you live close to a store in the city, you can just pick up something while coming home, or even when you're cooking you can just run to the store in 2 minutes to get something on-demand.

But you can't gradually go from one to the other so easily. You can't go with car to the local small store. There's nowhere to park etc. You can't go to the big box store in the middle of cooking because it takes an hour for the round trip.

So if you have person doing A, they see B as impractical "where would I park?". Or person B would say A is impractical because "I'd have to know cooking a week in advance". Both arguments are correct, you can't go from A to B or B to A by just changing one thing. You need a whole new big picture.

You can still do a mix sometimes, ie a person can do both, but not in the same situations.

Gravityloss··on Denmark Data Breach Exposes 8.8M People's Personal Data
This probably improves economic efficiency a lot. Want to build something and remember meeting a relevant expert 3 years ago at a party? Easy to find that person and start doing business...
Gravityloss··on What is going on with ceiling fans
I had a car that had non replaceable light bulbs in the rear blinkers, just a strip of led integrated deeply in the tail light assembly. Of course the blinker died. Replaced the whole assembly. (And replaced the whole car later). Apparently some enthusiasts do disassemble them and replace just the led strip, probably requiring soldering etc. This company had designed cars for about 120 years at that point but still seemed to commit easy mistakes...
Gravityloss··on Oxygen-deprived underwater zones may not be “dead zones” but clue to early life
I guess what we often ascribe to diffusion (hot and cold water mixing in a glass) is helped along tremendously by convection. But convection might get more easily started in a glass if the center and the sides are different temperature. Then you get this loop. But it might then not happen in a water heater since there's no lateral temperature differences.
Gravityloss··on Before pixels: Modular industrial dashboards
These designs seem so honest. Ie the maker really tries to communicate to the user.

Compare to most modern UI:s that are all about demos and looks and actually hostile towards users. I can't know what direction is hot and cold in the shower because it's light gray on silver.

Gravityloss··on Everybody’s home. No one’s coming over
But that's also great, meeting in a restaurant or bar. Or perhaps renting a cabinet space in one. Or just going on a picnic or free outdoor concert together. Doesn't need to be someone's home. I feel a lot of these things have shrunk massively.
Gravityloss··on An AI lab Tycoon game
In many good games you start small and there's only a few things available to you and decisions are easier. Ie in Civilization you start with one unit. Or with Railroad Tycoon you are trying to create one train track with one locomotive. It's relatively clear what to do. Then more concepts start arriving once you start making further progress.

It feels like here you already start with a large amount of things available and thus don't really know what to do, there's no gradual start.

Gravityloss··on The problem is not AI code, but not knowing about system architecture or intent
I just today found a term to describe what is happening: gradual disempowerment. I think it's a likely path. Everybody, because of competition, needs to end up giving control to AI.
Gravityloss··on A Model for Winning Survivor
I haven't followed these sort of programs, but aren't they promoting and celebrating psychopathic manipulative behaviour.

In real history, often what's at stake is survival of a community and people want to genuinely work together. Here for some reason it's an arbitrary forced conflict if only one individual can win.

Gravityloss··on EU chief opens door for Canada to become 'associate member'
CE is a tool against protectionism. If a thing is CE stamped, you must allow it to be sold (if you're a member).
Gravityloss··on EU chief opens door for Canada to become 'associate member'
I guess if going in the UK gets tough the royals could move somewhere else to reign. Sigismund was king of Sweden and Poland, though he couldn't maintain both. Maybe we'd need some drama with usurpers and uncles and so on to keep the populace entertained. Without the civil war part...
Gravityloss··on The Beauty of Roundabouts
In Sweden they have these huge roundabouts in the countryside. Very large diameter and gentle curves. You can maintain your speed. Awesome. Saves energy too. I assume there's a huge amount of tried and tested traffic innovation that could be directly just copied.
Gravityloss··on Cartesian – AI 3D Modeling for Design
These all seem backwards.

I like to think in shapes. I like to draw and sketch, as that has the lowest barriers between the mental concepts and physical ones.

I do not like to use cad software. It is painful to express ideas with it. Also same for all kinds of drawing software. It's just very cumbersome.

I hate explaining spatial or shape concepts to people with words. I hate having them explained to me in words.

A photographer doesn't explain his work, he shows photos he has taken.

Adrian Newey used to work with pen and paper while others had been using CAD for a long time, and won F1 championships.

Can we now make the computers less clunky and less about typing or hunting with the mouse. We want low friction to express ideas.

This seems the opposite. You're not expressing your idea, you're asking for the computer's idea.

Gravityloss··on I can't stop thinking about Papua New Guinea
Very nice music. It has the same song three times?
Gravityloss··on iOS 27, iPadOS 27, and macOS 27
At some point I got the damn Chess app every time I wanted to switch to Chrome. You know, typing cmd-space, ch and enter. I've learned I can't remove Chess from my computer. After numerous incantations of various spells and reboots and updates I think it started working normally again.

Breaking interfaces, Linus Torvalds had something to say about it that Apple should heed.

Gravityloss··on People who can't picture anything are rewriting the science of imagination
Hmm turns out I have hyperphantasia?

No wonder it feels it's hard to explain things to people a lot of the time...

Gravityloss··on Can guitar frets perform multiplication?
Those are so called flute sounds or harmonics, ie you don't press the string against the fretboard or fret normally at all. Instead you touch it very gently to force a vibration node there where your finger is. It doesn't work at all on most places along the string, you end up just damping the string. The easiest harmonic is halfway between bridge and nut, or at 12th fret, ie you force the string to vibrate with half the wavelength, or a node in the middle, or double frequency, or one octave higher, compared to free string. Then second easiest is 7th fret and then 5th (which is 2 octaves, ie quadruple frequency) and 9th. So you get less than pentatonic scale if you only use those, but they are useful pointers or anchors anyway.

But this is not exact!

Music harmonics are just about multiples. Ie one note rings at some frequency and another note that sounds nice with it rings at some multiple of it. Or they have some common factor. The twelve note system and the twelvth roots are just approximations for some of these harmonies. There's even very recent innovation like true temperament frets. But I don't think that works with all the different song keys and tunings... Maybe it's another reason why I should buy a guitar for every song key we have!

Gravityloss··on Can guitar frets perform multiplication?
Oh my god, it's a beautiful way to explain how slide rules work. Without spending a single word. Thank you!
Gravityloss··on Icy Moons Are Ocean Worlds
I guess I'm now officially old and cranky, as planetoids receiving glow-ups was just a bit much as a term.
Gravityloss··on 'You Can See Everything' Review: Nathan Fielder's Doc About Elizabeth Holmes
https://xkcd.com/385/

This sort of thing is really hard to avoid. If you've ever spent time as somehow very different in a social setting, you can see this happening all the time. Even in positive ways.

Gravityloss··on Is mathematics about to enter the conservatory?
I think often in families, if a generation is successful with money (for example as engineer or enterpreneur), then next generation often become artists or politicians etc.
Gravityloss··on The largest electric aircraft just flew [video]
But on this flight it did not have a combustion engine, I assume it was fully electric and if so, the title is 100% correct.
Gravityloss··on Audacity 4.0
For some reason, almost all audio apps have very odd scroll and zooming behaviour (and home/end keys also do weird things). Also doing basic things like starting playback or recording from start or from cursor tends to be quite complex in many of them. It would be interesting to know why that is so. Maybe it is so that you don't accidentally trigger it? If you're just doing editing and never recording, you never want to trigger recording with r, only with some complex modifier combo. But if you're a musician, that's about all you do, hit record and stop and playback and stop.
Gravityloss··on What the Hale?
I didn't read the whole thing but how would fizzbuzz or something like that look like in the language? I found lots of writings and examples but some basics are also nice for a person who wouldn't want to invest a lot of time at first.
Gravityloss··on How bicycle coaster brakes work (2018)
I have biked with lots of coaster bikes and lockup has never been a problem. Like with a lot of things, you just need a little bit of humble attitude and trial and error to get the feel and then once you get it, it gets easier and easier. I don't think they lock up easily at all.

Same if you drive an unfamiliar car, it's more bumpy in the beginning but your brain will adapt, especially manual gears. I remember some cars did have terrible clutches and gearboxes and very low torque engines so it felt intimidating as a kid.

Gravityloss··on The startling 1960s theory that Stonehenge was a prehistoric computer

Gravityloss··on Hy4 preview
And I wonder how they actually spoke. Since there was no visual communications medium except for cave art. (Some of which is very excellent. Try drawing 3d curved horns in perspective.) So people would have used verbal communication more. Also no written word. So one would expect there to be quite a lot of oral tradition. Like people reciting poem form epics.

If we assume the time is before farming, population density would have been low and limiting culture. Hunter-gatherers might have travelled a lot more than farmers with a homestead though.

Gravityloss··on Glacier Mice
And while not all the way to Venus, Earth's history has multiple mass extinction catastrophes that have happened. Some have been due to things like asteroids, or volcanism but also just chemical imbalance. An ice age is small beans compared to those...
