Comment Re:Welding helmets (Score 1) 90

Welding helmets work, but only if they are at least Shade 12 or darker.

Or if you don't trust ready-made glasses, just grab a bit of mylar (e.g. https://www.amazon.com/Baader-... ) and make your own.

I just bought some shade 13 welding glass plate inserts for helmets. Cost me about $8 each. They work just fine without a helmet, we made cardboard glasses from them for fun with the kids and they can also just be attached/held to a smartphone for easy photography/videos.

Depends greatly what you hold and when. Unsurprised a vax maker would be volatile during covid. You posted it was common. I submit it is not common. You can find volatility if you want, but the majority of stocks trade on actual earnings, and those don't change day to day. Meme stocks on the other hand, like the latest crazy, djt. You can find them, they are in the news. Most stocks are boring on purpose and don't scream look at me.

Are we in Covid now? Because the 5%+ drop was in todays trading.

I would argue the majority of stocks don’t trade on actual earnings any more than that’s what gives a fair amount of people confidence to buy. The reality is all stocks are manipulated by the larger players to the greatest extent possible to get the most money possible from the market, hence the adage the market can remain irrational longer than you can remain solvent.

I hold individual stocks. A 5% change in a day is big, at least with most companies. I just looked, I've got one at .4% down, one at .05% down, one 1.2%up, one at 1.5% up, one unchanged... You get the idea. On a day with an event, say take INTC which I don't hold, it is down 7% due to some very very bad news. I've held INTC in the past though, and a typical day at Intel is less than 1% change.

It’s not that unusual at all. I used to hold MRNA, got in at 130, sold up to @400 and got out my remainder at 130 again. It just dropped 5% today. News that interest rates are changing is quite a time honored cause of stocks changing value quickly.

Difficult to do when a relatively small number of whales are holding onto a significant portion of the available coins and they aren't selling.

Eventually one of them will blink and the price of the tulips will crash again.

Crypto will continue to be a domain that exists mostly to enable criminal activity and a novelty for most other people.

Good luck with that.

At this point a 5% drop in a day makes it a stablecoin. Go look at the stock market, individual stocks bounce like that all the time. I seem to remember a bit over a year ago it peaked at the same price it’s at today. If bitcoin does anything really reliable it’s peak and crash with a period of about 1-2 years. Anyone who bought in at 60 back then near the peak and was called a fool could have sold at 70 just a few days ago and made a reasonable rate of return. If I had to bet I’d say we are either peaked, or close to it and it will hit 80k sometime before the end of 2026. If it’s manipulated they can only maximize gain, not price differently to individuals so by not following the crowd and embracing you missed out and waiting till a trough to gamble they have little they can do if you hold.

There have been a number of cases of "accidentally fell through a window" in Russia that most actually attribute to quite deliberate defenestration.

Nonsense. Why the Russian people are quite fastidious in nature and often expire with a flourish of bravado. Simply shooting oneself in the back of the head a few times, tying themselves up in a sack, and throwing themselves out of a window so as to not inconvenience the elevator riders is just the start. Couthness means proceeding to drive into a body of water and truly embody reticence.

there's apparently a young (also predominantly male) demographic that is embracing manual driving — championing it as retro, much like Gen Z's affinity to typewriters and vintage cameras.

Ok. But:

[Automatic vehicles] chalk up better mileage and drive faster than their stick-shift counterparts. The explanation: automatics select the right gear for the vehicle, usually the highest gear possible. The average manual driver is not always so proficient.

So let me get this straight, people who love retro things, renown for their inefficient use compared to modern solutions, and who love to floor it and play with a physical transmission are going to care about a percent or two in efficiency? When the costs of making an automatic transmission results in more greenhouse gasses up front and these are the people who are going to be flooring it everywhere and get poor mileage anyway?

The costs of modern computer run automatics still can’t beat a driver that shifts with the best mileage in mind, this can simply be displayed as when and how to shift, a decades old technology. What this is about is limiting people’s right to choose, and in places like Europe and elsewhere, be required to pay more money for a car that cost more in a never ending car cost bloat. The average new car in America is nearly 49k now ffs. What we need are engineering decisions and better marketing, or at the very least be honest and not false frame the argument for internet outrage clout.

I have been driving manual for most of my life, and yes I like it much better. In the winter it get much better control in slippery conditions. But:

I think there is is no need for a transmission for EVs. I remember reading about this long ago about how electric vehicles 100+ years ago claimed that as an advantage. Do modern EVs have a transmission ? I kind of doubt it.

EVs have a transmission of sorts, a single gear reduction typically around 4-1. This is because direct drive would require more torque, and thus current and magnetic field density that makes current designs sub optimal. This is possibly changing with modern axial flux motors that are able to more effectively utilize magnetic field density and currents in a small package while also retaining the efficiency and wide operational speed range. It’s important because already dual motor EVs offer complete isolation and torque balance between front and rear, something that costs a lot extra in single engine designs. Further, designs are moving to each wheel having its own motor which allow for precise computer traction control and performance that are simply not feasible due to size and weight constraints using a single engine.

Effective crust thickness changes - from ice loss. Even if no change in gravity, that means the remaining crust must rise to equalise.

Sure, but think of how this happens, the crust is floating on the liquid underneath, all else equal you are just moving the floaty bit from one location to another. That won’t change the level anywhere else. The effect of moving the mass on the surface from the poles toward the equator is far greater than any other redistribution difference makes in the final mass moment.

While the ice at the poles continues to melt at pace, allowing the ground there to rise up, sinking the equator, so thereby driving a faster spin to conserve momentum, it is overpowering the slowing effect of the moon's tidal drag.

And that's what's so jaw dropping about it. Humans are now imparting more force on the planet than the Moon is!

From TFA

Earth’s speeding up because its hot liquid core — “a large ball of molten fluid” — acts in unpredictable ways, with eddies and flows that vary, Agnew said.

Agnew said the core has been triggering a speedup for about 50 years, but rapid melting of ice at the poles since 1990 masked that effect. Melting ice shifts Earth’s mass from the poles to the bulging center, which slows the rotation much like a spinning ice skater slows when extending their arms out to their sides, he said.

This makes sense because when the ice melts there is no significant change in local pressure since gravity stays the same and the total deformation is small compared to the mass moment water moving (generally) toward the equator. Think of it like the way ice floating and melting does not change the water level. It’s the core that’s speeding things up and the water moving toward the equator causes, largely by human caused climate change, was subtracting off that increase. The moon only subtracts 0.0023 seconds per century while the water moving toward the poles is far higher so you are correct we are having a larger effect than the moon, but just a bit differently from your description.
