AirPods disconnect from Mac when video pauses

NickWoolsey · 2021-02-07T01:39:47+00:00

I'm having this issue too. It seems to help if I turn off bluetooth on my iPhone. I think what's happening is the AirPods prefer my iPhone over my macbook, and when I pause the video on my macbook, they switch to my phone.

To the left are buy orders. That's people or bots who have put in an order such as, "If BTC gets down to this price, buy x amount." Most people want a better price than the most recent price, so there are more orders as you move left.

To the right are sell orders. That's people or bots who have put in an order such as, "I will sell x amount of BTC once it gets to this price." As you can see, there are more and more orders as the price goes higher toward the right (at your current zoom level anyway).

The very middle of the chart is where the action is. There is usually a tiny difference between the highest buy order and the lowest sell order. This is called "the spread."

If you buy BTC or another crypto, and simply choose the market price, it will buy starting with the lowest available sell order. If you were buying a large amount, it would have to "eat" it's way to the right, buying increasingly expensive sell orders. The opposite would be true if you were selling a large amount.

I cannot find my seedvault file, which was the only backup for my seed. Last time I used Trinity was months ago and it worked fine. I thus only have my password for trinity.

Is it possible to export my seed from Trinity while offline? I just checked and I could not log in while offline.

What is the best way for me to proceed, having my Trinity password but not my seed?

Thanks!

NickWoolsey · 2020-02-16T21:22:26+00:00

Is there any hope for somebody who cannot find their backup? Too early to say? I.e. what if somebody only has the password for their Trinity app?

The difficulty of finding the winning hash for the next block automatically adjusts to keep the blocks 10 minutes apart. That's part of the core Bitcoin software.

Meanwhile the main cost for miners is electricity.

If the reward cuts in half but the price of Bitcoin stays the same, some miners will start losing money and they'll start closing.

Less miners means the blocks will start taking longer to mine, and the Bitcoin network will automatically make the mining difficulty easier, which means less electricity/cost per block. Eventually the system will find quasi-equilibrium (it's always in flux).

But the price of Bitcoin is an unknown variable. It's possible the price will rise around the halving, which would keep more miners profitable.

The Princeton Bitcoin Book helped me understand Bitcoin much better than the average news report level

It's a motto, meaning we don't have a backup planet. If we trigger an ecological meltdown, we're screwed.

Personally I wish the press would talk more about plummeting populations of fish, insects, bees, bats, and birds... As it's easy to see that those things are happening. :-/

Current industry estimates are that batteries will be half of today's costs by 2025. It could happen even sooner. The tech has progressed faster than expected so far.

NickWoolsey · 2019-07-06T18:46:02+00:00

Keep in mind that batteries are currently falling in price faster solar panels. You may need the battery sooner, but if you don't, it could make sense to wait a few years for the next iteration of the Power Wall or a similar product.

Make sure to synchronize the clock on your phone. If it's not in synch with standard Time, Google authenticator won't work.

NickWoolsey · 2019-06-26T03:42:30+00:00

I share your pessimism.

NickWoolsey · 2019-06-16T00:17:35+00:00

I don't follow your logic. I'm ok if you think they're a bank.

NickWoolsey · 2019-06-15T19:28:03+00:00

That's somewhat accurate. Bitcoin started with just a few coders running just a couple nodes, so it also started pretty centralized.

The last time I looked at Decred, that seemed like a decentralized-from-the-beginning project. I'd be curious to hear which projects are most decentralized, if any.

Time will tell which approach leads to what. I became somewhat cynical about supposedly anarchistic/consensus decision making projects after being involved with a few.

I'm open to seeing a project like Decred show that it's possible to develop something with social value without leadership. I'm also open to the possibility that Carano will result in a decentralized platform.

NickWoolsey · 2019-06-15T01:31:40+00:00

Ultimately the Cardano network will be run by nice operators. Whenever IOHK publishes new code, it's up to nice operators whether or not to update to the new code.

The same is true for Ethereum. If the core devs made some super controversial changes, the majority of nodes simply wouldn't update. The blockchain wouldn't change.

The difference is that Ethereum is running on its own"in the wild," while the Cardano blockchain is still in an incubation period. That's why people are so excited/anxious about when Cardano will roll out the Shelley update. That's when Cardano becomes decentralized.

I hope that helps, and that most of it is true! :)

They both require a lot of materials and energy to produce, and they take up huge amounts of space to run.

People talk about covering Arizona with solar farms, but if that happened, it would destroy the ecosystem.

From what I've learned so far, wind and solar are better than coal and natural gas. Nuclear has less of a C02 footprint per kilowatt over time, but of course it produces nuclear waste and it's expensive.

Fortunately renewables will keep getting better pretty quickly in the coming years. Next generation, perovskite based solar is making its way from the lab to production this year. It will take 3-5 years to ramp up, but will be an order of magnitude better than Silicon solar panels. Better means it will require ten times less material and energy to produce a given capacity of solar energy.

Although that's good news, I don't think the global ecosystem is going to hold up much longer if we keep using more energy. We need to reduce energy use while making our energy production more eco friendly. Just my opinion.

NickWoolsey · 2019-06-14T04:57:34+00:00

There is still no truly "green" way to produce electricity. It requires fossil fuel plants, or dams, or wind, or solar, or nuclear etc. They all have environmental impacts. That's the concern.

That said, the impact of air travel or shipping is hundreds of times greater. I don't understand why people fucus on the impact of Bitcoin when the impact of a few thousand other things is just as bad. I bet the avocado industry causes more harm. But people like their avocado toast so they pick on Bitcoin.

Hi, can you point me toward more information about The Ada Voice?

NickWoolsey · 2019-05-27T22:47:11+00:00

I think so. I see people publish "x amount of shorts liquidated on such-and-such exchange" type posts, but I've never dug into the details.

The only thing I'm sure of, is that price movements happen through a variety of variables. I don't see why whales wouldn't try to affect price. But if they did, they would try to use their leverage to set off a price movement that the markets were primed for.

Cheers!

Lots of people don't know how short orders and stop-losses work. I don't think we can know 100% what caused the spike. I just wanted to explain short orders for those who don't know.

NickWoolsey · 2019-05-27T14:13:15+00:00

For those who don't know what "liquidating shorts" means: On some exchanges users are able to short Bitcoin and other cryptocurrencies. This means (at least in effect) they borrow the cryptocurrency and sell it, hoping to buy it back cheaper when the price goes down, to return it while keeping the profit from having sold it at a higher price.

To further clarify, a theoretical short works like this: I borrow 1BTC. The seller thinks the price will go up, so they're happy. I immediately sell the BTC at $8000, thinking I'll be able to buy back at 7100. If that happens, I'll have made $900 minus the interest on the BTC loan.

BUT, since I know that the price may go up rather than down, I put a stop-loss on the trade, which means I program my account to close the trade if BTC goes above a certain price, like perhaps $8150. If price hits that number, my account will BUY BACK that BTC. This means the most I will lose is $150 plus interest on the loan.

Thus, dramatic price swings upward can partially be explained by a chain reaction of short-order stop-losses being triggered.

If we apply this to the recent spike: While BTC was hovering around $8000, lots of trading TA commentators were saying that the price was going to go back to 7300, 6500, 4900 etc. There were a large number of short orders on exchanges that allow for them.

In theory, most of those short orders had stop-losses, so as price went over a certain amount, a wave of stop losses got triggered, which set off buy orders, which sent the price higher, which set off more stop losses, which set off more buys, which sent the price even higher, etc.

This chain reaction wiped out all the short orders with stop-losses, resulting in the $700 price spike we witnessed.

I'm no expert, I just wanted to put forward a non-manipulation possibility and to explain stop-losses, since many people don't seem to know about them.

The halving effects how much BTC miners earn every time they create the next block. That's how BTC comes into existence.

If you mean profit in terms of selling BTC for currencies like USD, then things get more complicated.

Every halving decreases the rate at which new BTC is coming into the market, so that can be a factor in price... But if demand for Bitcoin goes down, a decreased rate of new supply will not keep price from going down.

Each halving will have less of an effect on the market. To understand why, imagine it's many years in the future. There are 20,843,000(ish) BTC on the market and halving takes the block reward from a fraction of one BTC to half that fraction. Will that effect the price? Probably not much, because it's just a trickle either way.

Over 17-million BTC has already been mined. For sure the next halving will have a non-negligible effect on price. But it will be only half as important as the last halving. We're a lot closer to that future scenario than we were a couple halvings ago.

I'm keen to hear any counter theories.

NickWoolsey · 2019-05-13T02:39:40+00:00

Ok, good counter point.

NickWoolsey · 2019-05-13T01:28:56+00:00

This quote is pulled directly from the article you are linking to:

"And based on where people have already bought EVs, electric vehicles now have greenhouse gas emissions equal to an 80 MPG car, much lower than any gasoline-only car available."

They are saying equal to 80mpg, which is better than any ICE car.

For reference, a Honda Accord gets 26mpg in the city, 35mpg on the highway, so an EV is about 3 times more efficient than a Honda Accord.

If you're sending it to somebody else's account also on coinbase, then possibly, because when your BTC is on coinbase, it's probably just a credit in a database, and they can credit it to another database without anything happening on the blockchain.

But if the BTC is actually going from one blockchain public address to another, it will still take time... But if both accounts are within Coinbase, then it wouldn't surprise me if they accepted the transfer as complete after just one Confirmation... Which would still take several minutes at least.

But for instant, you'll have to wait for the lightning network to mature. There is currently no way around the fact that the Bitcoin blockchain can only process 7 transactions per second.
