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.

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...
Gravityloss··on Benjamin Franklin’s alter egos gave him the most freedom
Thank you for this comment. It is interesting and also beautifully written with no fluff.

For some reason few web pages, blogs or even tweets are written in this style.

Gravityloss··on Europe's last regular standard-gauge steam passenger service
We rode a birch log powered narrow gauge steam train and it was absolutely splendid. There was some smoke but it was nice and adding to the experience. Mostly it was steam clouds. Open and closed carriages were available. It was very slow mind you.
Gravityloss··on Climate change is strengthening El Niño, coral records suggest
I'm thinking of the Ottomans capturing Constantinople. Very much paraphrasing: Since Ottomans had a massive cannon made with new technology. Since Constantinople hadn't hired the cannon inventor. Since Constantinople was poor. Since it was sacked by other christians in the crusades previously. So it was self afflicted by christians.

One can see the climate crisis like that. Only global accords work, otherwise self-limiting CO2 is mostly sacrificing one's economy while others do better. USA will block all international climate accords. Because the president and half of politicians acts like climate change is not real. Because a whole party thinks that. Because voters think that. Because the media tells them that. Because the media treats fossil company propaganda like science. Because it's so cheap for a handful of companies to corrupt media or politics.

What is the epistemology of the majority of voters... scandals, conspiracy theories, UFO:s. What shows on TV or on your feeds. I assume it's child's play for some non-western actor to cause constant infighting in the west, causing billions in economic losses or destruction of alliances. For whole planetary level issues, who's the opponent, working in the shadows? Maybe, after all, the aliens are already here...

In a large part of the world, the people voted for those people.

On the other hand, there's also a market for generating outrage and panic, sometimes justified, sometimes not.

Gravityloss··on Bomb fishing is wreaking havoc on Indonesia's coral reefs
Ah, but minutes (or an hour) don't have any context to a person. "A bomb dropped every two thirds of the duration of a football game, excluding breaks". No, that sounds too mathy. Perhaps "three bombs per two games".
Gravityloss··on Tooltips need a delay, and then they need to skip it
In FPS maps like Quake you only realized how much invisible clip blocks the map makers put in once you play an amateur map that doesn't have them. You hit things, get stuck and can even get crushed and die. Or you can try and play an early version of some popular multiplayer map that doesn't have them and it's way less playable.

A lot of new creators of course will not believe you if you tell you have to do these affordances. I once tested a person's multiplayer map where a door had a central lip that crushed you if you entered off-center. I told them that it should be fixed, but the answer was "you should always go through doors through the center". It's some sort of very enticing idea of purity. "My map will only have real architecture and no affordances." In the end it will self correct.

Gravityloss··on Andreessen Horowitz is investing billions into a bleak future
Sure, there are effects like that power corrupts. But there are differences between powerful people.
Gravityloss··on Flat Chair by Sara Paculdo
A lot of other modern furniture looks like it was just the default in CAD. Ie completely rectangular arm rests with sharp edges etc. I get that a car like Ford Sierra looked featureless and too simple in its time, I guess it seemed like lazy design. Where were all the trims and grilles and fenders and in general the "borders between things"? But I think it didn't hurt its usability.
Gravityloss··on Mycorrhizal Infrastructure Map
Does it correlate with human longevity?
Gravityloss··on Exercise intensity modulates interorgan communication and is associated with
Thought experiment, not completely serious but something worth considering.

This would be 5 h per week, or 250 h per year, or over 10 years, 3.5 months of continuous 24/7 exercise. This is a large amount of training. 4% of your waking time would be spent on exercising. Or 6% of free time. At what point does it turn net negative, ie as time that it eats away from life. You can't attend events or hang out with family since you're always at the gym. I have understood smoking reduces your life span 8%. On the other hand, if you replace watching reels with gym, maybe it's also positive time otherwise.

Gravityloss··on IBM Simon (1994): the original smartphone, explained in its own ad [video]
The ad doesn't show me how the device works, there's just a person talking and making promises. I guess the device's resolution and contrast are so low and it looks a bit underwhelming in general that they didn't go with that first...
Gravityloss··on Tell HN: I never mean to flag anything
Weird, I have the same, I don't remember flagging these stories, though there aren't that many. Maybe on mobile it's easy to misclick...
Gravityloss··on Heart aerospace completes first flight of largest electric aircraft
I've flown from Helsinki to Tampere, under 200 km, long long time ago. The cabin personnel had to push the refreshments trolley uphill and downhill the aisle as there was not much level flight portion. I don't really know why it even existed as a route. National carrier and I assume there was a subsidy involved. Back then there was not much security so there was a lot less overhead. Still, a direct train route and road exists and all, so it was very redundant.
Gravityloss··on Heart aerospace completes first flight of largest electric aircraft
Lots of places have water or mountains preventing car or train travel or making it go the long way around. Ferries are slow. Those would be natural applications for this. Tallinn-Helsinki city pair for example.

I wonder, if this can get approved or certified somehow now, if then modifications and improvements are relatively easy, as long as many aspects like the pilot interface stays the same. Battery technology improves constantly after all.

As an example, going from the current 200 km range to 400 could make it very useful in numerous regions certainly.

Gravityloss··on Tom Stanton's supersonic trebuchet breaks sound barrier with gravity alone
That's absolutely incredible. I would never have thought of that. Thanks!

Gravityloss··on Tom Stanton's supersonic trebuchet breaks sound barrier with gravity alone
There were designs to hurl masses from the Moon also with a sling. Massively less infrastructure than a linear mass driver.
Gravityloss··on São Paulo resident transforms degraded area into urban forest
Sure. Many pines can survive forest fires. But some other trees don't or are short lived anyway. I never suggested trees live forever. But 100 years is not a long time for many.
Gravityloss··on São Paulo resident transforms degraded area into urban forest
It's the asymmetry at play. It takes a few minutes to fell a tree. While it takes decades to grow. To grow an actually fully grown 100 year old tree is a multigenerational project.

How could you foster such things? There's always short-sighted people and generations, it's close to impossible to make this happen. I've seen it personally when relatives have felled century old yard trees planted by our ancestors, for no practical purpose. There is at least one foundation that attempts to preserve forest, with strict rules, which has received already some donated forests. But who knows how that can be corrupted over the time forest actually takes to grow.

Gravityloss··on Claude Is Down
Well, because of this outage, I tried Kimi, and while the instant model works, K3 has "server issue".

Eternal September from here on, ie now the masses are using AI as much as me and we have supply crunch for the next 7 years....

Gravityloss··on 7.1 Earthquake in Japan
I at least can see English translated version of NHK here https://www3.nhk.or.jp/nhkworld/en/live_tv/
Gravityloss··on Is this the end of the once-mighty GoPro?
Many years ago had my first Gopro camera that seriously overheated, sent it for repairs, they said there was nothing wrong with it. It literally turned too hot to handle after taking a few clips and wouldn't work. I think there was some serious hardware issue that caused it to then drain the whole battery.

Gave the brand a second chance some years ago. Couldn't export my videos from the app, it always hanged. So I couldn't share footage. Apparently a common long standing problem on forums.

Woved to never buy anything from them again.

Gravityloss··on Buried Apple feature turns an iPhone into the perfect kids' dumb phone
One can try putting themselves sometimes in the position of an old person. Let's say you have a heavy steel rollator with grocery bags hanging from the handles. You've spent an hour going to the store in the summer heat and are quite exhausted. Now try to enter your building. There's locked door that needs to be held open, and two thresholds, one for the platform in front of the door and one for the door. You can't go over the first threshold with your rollator as that would prevent the door from being opened.

Now, I think the assumed way to get in is to keep the door open with your body while simultaneously lifting the rollator over both thresholds. This requires considerable strength, as you have to reach far with a heavy weight. Maybe an athlete could do it. Not an old exhausted person.

An old person needs to first leave the rollator out, open the door and make it so it stays open with a hook. Involves crouching and working with your hands close to the ground. Then lift the rollator one by one over the steps and go inside. Then come back out and close the door.

A foot operated door stopper and a few slopes could probably ease that up tremendously.
